Waste Into Treasure, Waste Battery Into Lighting Street Light

2019-05-24

If the used alkaline battery is not properly disposed, it will cause great damage to the environment. In order to encourage people to concentrate the waste alkaline batteries, some designers have designed such a street lamp that fully utilizes the [waste heat" of used batteries. The bottom of the street lamp is equipped with a plurality of holes of different sizes, which can be adapted to different types of batteries. Since the LEDs are provided with high-efficiency LED lights, the remaining power in the battery can be fully consumed, and the user only needs to use the used waste. Place the battery in the appropriate hole. It is also convenient to recycle after the power is completely exhausted.

Road lights The road is the artery of the city. The main lighting is a street light, which is a lighting device that is set on the road to provide necessary visibility for the vehicle and pedestrians at night. (between: 0667744.com). (Cement guardrail road lights can improve traffic conditions, reduce driver fatigue, and help improve road traffic capacity and ensure traffic safety. Garden Lights, Landscape Lights and street lights form a three-dimensional lighting pattern, enhance the road decoration effect, beautify the city night scene, also Can make up for the lack of Road Light illumination. Road lamps need reasonable light distribution, and their light sources have the best longevity, and they are used for years without maintenance. High luminous efficiency, good color rendering, and the ability to start normal work instantly under ultra-low temperature conditions. Currently, incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, low-pressure sodium lamps, electrodeless lamps, metal halide lamps, and fluorescent lamps are common among road lamps. At present, the main products of street light sources are still high-pressure sodium lamps. In recent years, the state has vigorously promoted energy-saving and emission reduction, and electrodeless lamps are new light sources compared to traditional light sources. Electrodeless lamps can achieve better road surface uniformity. Road lights should use light energy rationally to prevent glare. The light emitted by it should be irradiated along the required angle and fall onto the road to be a specified pattern. The light is evenly distributed, the road surface is bright and the glare is small. To reduce glare, light distribution can be controlled above the maximum light intensity. According to the form of the road section, the width, the situation of the vehicle and pedestrians, the road lights can be symmetrically arranged on both sides of the road, staggered on both sides, and arranged on one side and centrally suspended on the road. In general, roads and welcome roads with a width of more than 20 meters can be symmetrically arranged on both sides; where the width of the road is more than 15 meters, staggered arrangements on both sides can be considered; narrower roads can be arranged on one side. At road intersections, corners, ramps, railroad crossings, crosswalks and other special locations, road lights are generally required to facilitate the identification of road conditions by drivers and pedestrians. Illumination in the transitional sections between the inner and outer sections of the tunnel and from the urban streets to the suburban roads requires consideration of the adaptability of the driver`s eyes to light changes. The power, installation height and vertical spacing of road lights are important parameters for the design of light distribution. Combine these three factors to get a satisfactory lighting effect. Solar street light This system uses sunlight as the energy source for daytime charging and night use. It eliminates the need for complex and expensive pipeline laying. It can freely adjust the layout of the lamps. Safe, energy-saving and non-polluting. The charging and on/off process uses intelligent control, automatic switching, and no manual operation. It is stable and reliable, saves electricity, and is maintenance-free. It is suitable for road lighting and decoration in public places such as residential quarters, villas, parks and squares. The design uses metal, engineering plastics and other materials die-casting lamps, novel design, beautiful appearance, simple and neat. The lamp post is spray-sprayed and anti-corrosion-treated. It is durable, pleasing to the viewer, practical and integrated. Working principle: the sun shines on the current generated by the solar battery plate to charge the battery through the controller, and the battery electricity is used by the controller to become a direct current supply (electrical load), or to be used as an alternating current for the load by the inverter. The solar photovoltaic system consists of a solar panel (group), a solar controller, and a battery (group). If the output power is AC 220V or 110V, an inverter must also be configured. In the specific design of system engineering, the following factors should be considered: 1. The actual total power and usage time of the load (electrical appliances) should be set aside for the normal working time of the system; 2, the local effective sunshine hours; 3, the local weather data, such as continuous rainy days; 4. The location of the construction system must be open. There must be no tall buildings or other things blocking the sunlight when installing solar arrays; The conventional configuration of our company's panel components: solar cells are a single power generation device, which is equivalent to a battery with a voltage of about 0.5v; and the panel component is equivalent to a battery with multiple batteries connected in series or in parallel. . The number of solar panel components is usually determined by the system voltage (battery voltage), which is usually 1.4 to 1.5 times the battery voltage. For example: The battery voltage is 12v, the module working voltage is generally between 16.8-18v, then the battery piece quantity is 18v/0.5v, namely is 36 pieces. Therefore, the number of commonly used cells is 36 or 40, and the number of high-power components is 72. (Note: The specific parameters should be based on local weather conditions and user requirements) High Pole Lights High pole lamp: generally refers to a new type of lighting device consisting of a steel column pole with a height of 15 meters and a high-power modular lampshade. It consists of a lamp cap, internal lighting electrical, rod body and basic parts. Lamp shape can be based on user requirements, the surrounding environment, lighting needs and specific; internal lamps and floodlights, floodlights, NG400 high pressure sodium lamp, lighting radius of 60 meters. The rod body is generally a cylindrical body structure, which is made of rolled steel plates. The height of 25-40 meters refers to a new type of lighting device consisting of a steel column pole with a height of 25 meters or more and a high-power modular lamphouse. It consists of a lamp cap, internal lighting electrical, rod body and basic parts. The shape of the lamp base can be determined according to the requirements of the user, the surrounding environment and the lighting needs; the internal lamps and lanterns are mostly composed of floodlights and floodlights, and the light sources generally use high-pressure sodium lamps and metal halide lamps. The lighting radius is up to 60 meters. The rod body is generally a cylindrical body structure, which is made of steel plate and has a height of 15-40 meters. High pole lamp configuration 1. The light pole is an octagonal or dodecagonal tapered rod body, which is cut, bent, and automatically welded by high-strength and high-quality steel plate. The height is generally 25, 30, 35, etc. The design maximum wind resistance is up to 60 meters. /sec, each specification consists of 3 to 4 plugs. With flanged steel chassis, diameter 1 to 1.2 meters, thickness 30 mm to 40 mm. 2. The main function of the framework structure, there are also mainly decorative materials to steel through, steel-based, lampposts, lamp pan hot dip galvanized. 3. Electric lift system consists of electric motor, hoist, three groups of hot dip galvanized wire ropes and cables. The lamp post is installed inside the body, and the lifting speed is 3 to 5 meters per minute. 4. The guiding and unloading system consists of guide wheels and guide arms to ensure that the lamp pan does not move laterally during lifting. When the lamp pan is lifted into position, the lamp pan can be automatically released and locked by the hook. 5. The lighting electrical system is set up with 6-2 4 4 0 0 w-1 10 0 w gold halide (white light), cast light, floodlights, computer time controller can automatically control the switch light time and part of the lighting or full illumination. 6. Lightening protection system: 1.5 m long lightning rods are installed at the top of the lamp, and a 1 m long grounding line is installed at the underground foundation and welded with the underground bolts. High pole lamp use place The use of pole lights: city squares, stations, docks, freight yards, highways, stadiums, overpasses. High pole lamp classification Generally can be divided into lifting and non-lift type. Lifting height of the main pole is generally more than 18 meters, electric lifting operation is convenient, after the lamp pan rose to the working position, it can automatically take off the disc, hanging ditch, wire rope unloading. Elevating mast lamp is provided with manual and electric two lifting control modes, so that the lamp panel can be safely and reliably lowered to 2.5 meters from the ground, which is convenient for maintenance work. The length of the lead wire of the manual remote control device is 10 meters. The operator can remotely control the rise and fall of the lamp panel at 5 meters, so as to ensure the safety of the operator. The elevating mast lamp is also equipped with a spare cable. When the lamp panel is lowered to the lowest position, one end of the cable is inserted into the socket of the electrical control system, and the other end is inserted into the junction box on the lamp panel so that the lamp panel can be directly powered. , repair lamps. All the lamps and lanterns of the lifting pole lamp are sealed to the IP65 international standard to prevent dust and rain from immersing and ensure the service life of the bulb. The material of the lamps and lanterns is generally made of aluminum alloy plate and stainless steel with good corrosion resistance. High pole lamp lifting principle In the rectangular cavity at the bottom of the elevating mast lamp, a lifting system such as a motor is installed in addition to the electrical control system. The electric control system is installed inside the lamp pole to avoid the malfunction of the lifting and lowering movement caused by the harsh outdoor environment. Various circuit overload protection devices are provided in the electrical control system. Copper-based silver plating is widely used for the electrical conductors of the circuits in the system to ensure good electrical contact. The elevating mast lamp lifting system drives the lamp pan to move up and down by means of electric motors, (electromagnetic brake) worm gear reducers, safety couplings, main steel ropes, auxiliary steel ropes, rope separators, and moving pulley blocks. The worm gear reducer has a strong self-locking ability, a compact drive, and a large transmission ratio. In order to reduce the gear ratio of the worm gear and the worm, the rise torque is reduced, and a set of moving pulleys is added, so that the speed of the lamp pan is less than 0.2 m/s. . The main steel wire rope is connected with the lamp pan deputy steel wire rope through the rope separator, so as to avoid the winding of the auxiliary steel wire due to the stretching of the main steel wire. The main and auxiliary steel wire ropes are made of high-strength corrosion-resistant 6*19 non-rotating galvanized steel wire ropes. Lifting pulleys are all made of hot-dip galvanized A3 steel brackets, stainless steel shafts, and copper pulleys to ensure that they do not rust and run smoothly under normal atmospheric conditions. Various fasteners washers, collars and other parts are also used hot dip galvanized or stainless steel. There are 6 sets of guide pulley blocks and more than 3 sets of braking devices on the lamp pan. The guide rollers with a 120-degree distribution during the lifting or lowering of the lamp pan roll along the surface of the lamp post to ensure that the lamp pan does not oscillate. The surface of the working part of the guide wheel of the lamp pan in contact with the surface of the lamp stem adopts a rubber heat pressing process. In order to fully ensure that the lamp panel automatically stops when it reaches the limit position, the lamp pans are equipped with reliable limit switches for rising and falling motions and are equipped with over travel protection. The lifting of the high-pole lamp panel is achieved by changing the direction of rotation of the motor. For security and security, the rectangular cavity is equipped with a sealed door and a special door lock is mounted on the sealed door.

First, the type of street light There are various types of street lamps. According to the light source, LED lights can be divided into LED street lamps, induction lamps, energy-saving lamps, high-pressure sodium lamps, metal halide lamps, etc. According to the occasion, they can be divided into ordinary street lamps, high-post street lamps, courtyard street lamps and landscape street lamps. Others can be divided into single-arm street lights, dual-arm street lights, combined street lights, solar street lights, and so on. Second, street light source The street light source has LED light, induction lamp, ordinary energy-saving lamp, high-pressure sodium lamp, metal halide lamp, etc. Which kind of street light source is good? Metal halide lamps and ordinary energy-saving lamps are not costly, have a long service life, and are easy to maintain. However, such street lamps have relatively high power consumption and are not recommended. High-pressure sodium lamps have a good fog-passing performance and are a type of street light source commonly used in the past. However, its life and energy efficiency are relatively poor, so the street light source is not recommended to choose high-pressure sodium lamp; the electrodeless lamp is also a kind of energy-saving lamp, the theoretical life is also quite long, but the cost is high, the maintenance is not easy, such light source is not recommended; Street light LED light source is the most used light source in recent years, high efficiency, energy saving, environmental protection, long life, convenient maintenance, and the price is not expensive, and many countries and regions are vigorously promoting LED, street light source selection recommended LED, LED street light is the road Lighting is preferred. Third, the street light interval The street lamp spacing is also the street lamp spacing, which is determined by various factors such as the lighting power of the street lamp, the height of the street lamp, and the width of the road. The street lamp spacing is typically 3.8-4 times the height of the pole. The longitudinal spacing of street lamps is generally 30 meters to 50 meters. When there are power poles or other poles, the spacing is 40 meters to 50 meters. Try to combine the power supply pole with the lighting pole to save investment. If the underground cable is used for power supply, the spacing should be small, which is conducive to the uniformity of illumination, and the spacing is usually 30 meters to 40 meters. Fourth, the height of the street light The height of the street lamp (the height of the street lamp pole) is generally 6 meters, 8 meters, 10 meters, 12 meters, 15 meters, etc. The specific use of the street light height depends on the width of the road surface. Generally, if the single side light is on, the height of the street light is the same as the width of the road surface. Or the height of the street light is less than 1 meter of the width of the road. The relationship between the common Led Street Lamp power and the pole height is generally: 30~60W street lamp height is less than 6 meters, 60~100W street lamp height is below 8 meters, and 100~150W street lamp height is below 10 meters. 5. About the street lamp The street lamp management office is a sub-disciplinary full-budget institution. The main responsibility is to be responsible for the planning, construction, management and maintenance of county road lighting. It is responsible for the lighting management of public places and scenic spots in the county, and is responsible for the energy-saving utilization of road lighting products. The county roads are brightened and the supporting construction of buildings (structures) and the construction of street lamps in towns and towns. Six, LED street light manufacturers According to the statistics of global LED street lamp installations in 2014, the current global installation of street lamps is about 200 million , of which about 65 million in Europe, accounting for more than 30%, and about 44 million in the United States, accounting for more than 20%. About 4 million baht, China is about 33 million baht, accounting for more than 16% of the world. In 2015, the global LED lighting market will reach US$21.7 billion. By 2015, China's LED street lighting market will be about 23 billion yuan. The overall market penetration rate of China's LED road lighting products will exceed 45%. The global LED street lamp market has experienced rapid growth since 2010, with a compound growth rate of 97.75% from 2009 to 2013. In 2013, the global LED street lamp market reached US$2.159 billion. Along with the rapid growth of LED market and LED street lamp market, traditional street lamp enterprises have transformed LED street lamps, and the development of new LED street lamp enterprises has also risen like a spring shoot. Everyone has also considered the choice of LED street lamp manufacturers.

Analysis on the development of outdoor street light pole LED display market prospects

2018-07-29

In recent years, with the development of the LED display industry and the increasingly fierce competition in the industry, in order to seize market share, LED display companies are seeking breakthroughs in the application of the product. In today`s big screen, what can LED display screens be? Do you have a place in the outdoor advertising market? LED lights bar screen to deduct, jackpotting Due to the popularity of LED large screens in outdoor advertising media, high-quality screen installation locations are becoming scarce resources for outdoor advertising. In addition to the negative impact of adverse factors such as light pollution caused by LED large screen on urban management, the approval process for LED large-screen outdoor installation location has become more and more complicated and difficult. In recent years, the negative impact of the global economic slump has had a greater impact on digital media other than landmark digital media. In 2014, LED advertising screen advertising declined generally. Under the circumstance of such background factors, the constraints of the development of outdoor video media have gradually become prominent, and the demand for small-area outdoor streetlight LED displays is gradually emerging. Compared to traditional lightbox advertising, video playback is better than video playback. The appearance of outdoor LED light pole screens is mainly to replace the commercial light pole light box advertisements. At present, light box advertisements on the market, double-sided emission advertisements, can discharge up to two advertisements, and the customer group has to change once in a few months, the number of advertisements placed is limited, and the LED light pole display can discharge advertisements without restriction, and The LED light pole screen can place dozens of advertisements at the same time, so the utilization rate of the light pole advertisements is correspondingly increased. On the other hand, in terms of visual impact, the light box advertising plane advertisement, while the LED light pole display can display dynamic video advertisements, and the form of delivery is also more attractive. In comparison, dynamic advertisements have stories and plots, and no one is watching them. As long as they are broadcast, there will always be people paying attention. The static advertisement is a picture. One or two sentences often do not express the meaning to be elaborated. This will attract fewer eyeballs, especially in the rush of the road. The audience will pass by and may still return. I didn't have time to pay attention to the existence of advertising. Therefore, the advantages of the outdoor street light pole LED display are obvious. National road traffic planning, market prospects are expected in the future Statistics show that as of the end of 2014, the total length of roads nationwide reached 4,463,900 kilometers, including 11,19 kilometers of highways, and the mileage scale ranked first in the world. Moreover, with the acceleration of the pace of urbanization development, it is foreseeable that in the next few years, in order to narrow the gap between urban and rural areas and urban development, the investment in road transportation planning in China will inevitably become even larger. The coming of 2016 means that China's "13th Five-Year Plan" has entered a new period of practice. According to reports, manufacturing upgrades, information economy, and modern service industries are expected to become the three main lines of the 13th Five-Year Plan. The state's emphasis on manufacturing shows that the future of new products LED pole screens is endless. According to the light main line every 50 meters, there is a light pole to calculate, there are 100 million light poles in the road of nearly 5 million kilometers in China. At present, the application of outdoor street light pole LED display can not reach 10% of all street lamps. If all the previous light box plane advertisements are replaced by LED light pole screens, plus the street lights position of new highways, then the LED light pole screens The market outlook is considerable. As a new thing, the LED light pole display needs to be explored step by step and explore a broader development opportunity in the exploration. Whether it is its own advantages or the unlimited market space provided by the national road traffic planning, I believe that the LED light pole screen can be favored by more advertisers!

Selection criteria for LED street light source and pole for different road grades

2018-07-29

In the EMC project, the general government or the manufacturer will mention the implementation of the test section in the negotiation with the government. What are the selection requirements for the test section? How can we implement a test section that is qualified and satisfactory to the local government? Let's explore it here. First, the test section should select typical road sections that are representative of the spacing, height, overhang, elevation and consistency of the light source. 1, spacing The street light spacing should be as small as possible. The preferred spacing is no more than 40 meters. It is best to choose a road with a 35 meter pole distance. National Standard "CJJ45-2006 Urban Road Lighting Design Standard" Street Light Pitch Reference Value: The height of the light pole of the cut-off type lamp is about 3 times the distance. Select the straight road and do not choose the curve or intersection. The cantilever length of the luminaire should not exceed 1/4 of the installation height, and the elevation angle of the luminaire should not exceed 15°; 2, road width The road width is preferably two-way four lanes (about 15 meters), and the road surface is flat and wide. 3, the height of the pole The height of the pole is preferably 8-10 meters, and the second choice is no more than 12 meters (the pole height directly affects the angle of light emission, which affects the uniformity of illumination). The cantilever hole of the lamp is preferably ¢60mm in diameter. National Road Standard Reference: The relationship between the type and arrangement of light distribution of lamps and the installation height and spacing of lamps Note: Weff is the effective width of the road (m) Need to pay attention to the above table, here is the point. Since the country has a specification for the distribution of street lamps, there will be different lighting options for different lamps in different test sections. For example: a large road is 18 meters wide, and the middle green belt is 2 meters two-way four lanes. How to judge the road as a test road section in the light pole and light distribution? solution: (1) Road qualitative main road 1, must use cut-off lamps 2. According to the above table, the distribution of the poles of this road is (1) Double-sided staggered lamp: The height of the pole is more than 12 meters, and the distance between the poles is ≤ 36 meters, which meets the requirements of the national and test sections. (2) Double-sided symmetrical cloth lights: the height of the pole is more than 9 meters, and the distance between the poles is ≤ 27 meters, which meets the requirements of the national and test sections. (2) The road is characterized as the secondary road 1. It can be used for light-cut or half-cut type street lamps (such as the use of cut-off type street lamps and the above conditions) 2. If a half-cut type street light is used, according to the above, the lamp pole distribution of this road is (1) Double-sided staggered lamp: The height of the pole is more than 14 meters, and the distance between the poles is ≤ 50 meters, which meets the requirements of the national and test sections. (2) Double-sided symmetrical cloth lights: the height of the pole is more than 11 meters, and the distance between the poles is ≤ 39 meters, which meets the requirements of the national and test sections. Conclusion: If you choose this section as the test section, then it is best to use LED cut-off type lamps, the best way to distribute light is TypeIIShort or Medium (please add, for the light distribution, please refer to the discussion about the light distribution of the lamps in my log. The basic formula when choosing the light distribution is: the height of the rod is H, the width of the road is W, and the quotient between them is equal to 1 to select Type I light distribution, less than 1 to 0.25 to select Type II, less than or equal to 0.25 to select Type III, and cast light The length is based on the width of the pole. (3) Way of lighting The conventional lighting method should be adopted, and the layout of the street lamp pole is called the best in both sides; The order of selection of lighting methods: Five basic ways of arranging conventional lighting fixtures (a) one-sided arrangement; (b) double-sided staggered arrangement; (c) bilaterally symmetric arrangement; (d) centrally symmetric arrangement; (e) lateral suspension arrangement (4) The replaced light source is preferably a high pressure sodium lamp: the higher the power of the light source, the better, the single lamp power is better at 400W or above, and the second is 250W or 150W. (5) It is better to test the obstructions and shades on both sides of the roads , and not to hinder the normal lighting of the street lamps; (6) It is better to choose secondary trunk roads or branch roads ; (7) Selecting the road section with less external auxiliary light source , which can reflect the lighting effect of LED street lighting. (8) Without any energy-saving devices , the voltage is relatively stable; (9) Road sections with less traffic flow and less traffic and good road conditions To sum up, with the government departments to do street lighting energy-saving renovation projects, we must first consider the energy-saving benefits of energy-using units as the primary consideration and strictly implement national standards. Secondly, it is necessary to reduce the investment risk of the energy service company and recover the investment income as soon as possible. The replacement principle of all luminaires must be based on these two points.
