Future development of LED street light manufacturers
The production of our LED street lamps must meet the following requirements in order to better meet the needs of users. First, the LED street lamp production requirements LED street lamp is the most widely used street lamp so far, because it is more energy-efficient and cheaper than traditional street lamps, so we are widely used. The production of our LED street lamps must meet the following requirements in order to better meet the needs of users. 1. The conversion rate of light is 17%, (1000W per square meter of solar energy, the actual utilization efficiency is 170W). 2. At present, the street lamp lens material is an improved optical material with a transmittance of 93% and a temperature resistance of -38 to +90 degrees. 3. LED street light lens, mainly used for LED street light lens, the spot is rectangular, the material is PMMA optical material, the transmittance is 93%, the temperature is -38 to +90 degrees, the anti-UV ultraviolet yellowing rate is unchanged for 3w hours. Wait. 4. The average illuminance of road surface illumination uniformity is 0.48. The spot ratio is 1:2. 5. Meet the road illumination. (The actual 1/2 center spot reaches 25 LUX, the 1/4 center light intensity reaches 15 LUX, the lowest light intensity 4 LUX at 16 meters, and the overlapping light intensity is about 6 LUX. 6. It has a very good application prospect in new urban lighting. Deep dimming, and color and other characteristics will not change due to dimming. 7. Adapt to humidity: 95% 8. Quality assurance: 2 years. 2. Product advantages of LED street lamps Street lamps are an indispensable part of our lives. In order to meet our daily needs, our street lamps have gradually changed from the original ordinary street lamps to the current LED street lamps. LED street lamps have more advantages than ordinary street lamps. Let us briefly introduce them to you. The power LED cold light source does not damage the irradiated object; the light source of different colors can be selected according to the need; the usage is the same as that of the traditional spotlight, no need to change the interface; it can be used in the harsh environment such as open air and high temperature and high humidity; low power consumption, environmental protection Energy saving, long service life and maintenance-free. High brightness: Solar cell module is used as the lighting system of the lamp and the optimal angle design of the solar panel provides sufficient energy for high-power LED High life: The life of solar modules and LEDs is up to 20 years. Energy-efficient: Solar cells are used to convert solar radiant energy into electrical energy without additional energy supply, zero emissions, no pollution. High intelligence: all switches are realized Automatic control, solar secondary road lights can reduce the output power of the light source to save energy when there are few pedestrians at night. High safety: low-voltage products, no harm to the human body. High-intensity connection between lamp bodies, wind resistance High. High convenience: easy to install, no need for trenching wiring, can be installed arbitrarily. Our company's LED street light adopts high-power LED, with bright colors, uniform brightness, low power consumption, long time-to-failure and easy installation. The future development of LED street lights With the acceleration of urbanization, LED street lights have already entered people's field of vision. Today, LED street lights are everywhere in the streets and streets of big cities. It is dotted with the night sky of the city. However, it still does not get the fullest. The use is nothing more than because of its own limitations. In order to ensure the LED road Lights can play more roles in our lives. In the future research, production, and promotion, we should solve these problems first: the shape and structure of the lamps. The shape of traditional street lamps is basically the same, generally For the light source and electrical appliances, but because of the special characteristics of LED light source and the different light distribution methods, the shape of LED street light fixtures can be described as numerous. Many of them can not meet the operational requirements, and even some enterprises are The internal standard is applied to outdoor street lamps. Second: There is a problem in the connection between LED lamps and poles. At present, almost all LED street lamps are fixed by screws, and few hoop bolts are fixed. Thus, for the safe operation of lamps There are great hidden dangers. The limitations of LED street lights themselves restrict their development: the replaceability of luminaire components. LED street light components generally have LED chips, power supplies (drivers), and lamp housings. The most vulnerable parts are power supplies and chips. In general, LED luminaire chips cannot be replaced, and the power supply (driver) can be replaced. However, many products are not convenient enough to replace the power supply (driver), and replacement is time consuming. As we all know, the life of LED lamps can reach 350,000 hours. If the LED chip cannot be replaced, it means that replacing the entire fixture will also result in waste. The fourth is the life of the power supply (driver). The power supply (driver) is a very critical component of current LED luminaires. But currently the market generally only guarantees the quality of the LED chip, and the life of the power supply (driver) is another matter. The average manufacturer promises to guarantee 2 years is not bad. This is ultimately because the development of LED street lights has encountered a new bottleneck - the quality of the power supply (driver) is not guaranteed, it restricts the development of LED street lights. The power saving effect of LED street lights. In theory, power saving, but in practical applications, LED street lights are not more energy efficient than high-pressure sodium lamps. Under the premise of lighting quality standards, high-pressure sodium lamp high-power lamps (250 to 400W) light efficiency, up to 130 to 140 1m / W. The high-power LED street lamp uses 1W LED tube. In theory, its light efficiency is similar to that of high-pressure sodium lamp. However, considering the three factors of ballast loss, lamp efficiency and track utilization, considering the current energy efficiency of LED than high-pressure sodium lamp Lower. The low-power LED street light (150W) is 10% more energy efficient than the high-pressure sodium lamp.
