Briefly describe the future production and promotion of LED street lights

With the acceleration of urbanization, street lamp manufacturers have already entered people's horizons. Now, LED street lamps can be seen everywhere in the streets and lanes of big cities, which decorate the night sky of the city. However, it still has not been used to the fullest, but it is because of its own limitations. In order to ensure that LED street lights can play more roles in our lives, in the future research, production and promotion, we should deal with these problems. First: the shape and structure of the lamp. The appearance of traditional street lamp lamps is basically the same, generally divided into two parts: light source and electrical appliances. However, due to the particularity of LED light source and the difference in light distribution methods, the appearance of LED street lamp lamps can be described as diverse, and many of them cannot To satisfy the requirements of operation, some companies even apply the indoor standard to outdoor street lights. Second: There is a problem with the connection between the LED lamp and the light pole. At present, almost all LED street lights are fixed by screws, and rarely with hoop bolts. In this way, there is a great danger regarding the safe operation of lamps. The limitations of LED street lights restrict their development. Third: the replacement of lighting components. LED street lamp components generally include LED chips, power supplies (drivers) and lamp housings. The vulnerable parts are mainly power supply and chip. Generally speaking, the LED lamp chip cannot be replaced by the electronic heat sink, and the power supply (driver) can be replaced. However, it is not convenient to replace the power supply (driver) in many products and the replacement is too time-consuming. As we all know, the life span of LED lamps can reach 30,000 to 50,000 hours. If the LED chip cannot be replaced, it means replacing the entire lamp, which will also cause waste. The fourth is the life span of the power supply (drive). The power supply (driver) is now a very critical component of LED lamps. But now the market generally only guarantees the quality of the LED chip, and the life span of the power supply (driver) is another matter. Generally, manufacturers promise to ensure that 2 years is good. In the final analysis, this is because the development of LED street lamps has encountered a new bottleneck-the quality of the power supply (driver) cannot be ensured, which limits the development of LED street lamps. The power saving effect of LED street lights. In theory, it saves electricity, but in practice, LED street lamps are not as energy-saving as high-pressure sodium lamps. Under the premise of lighting quality specifications, the luminous efficiency of high-power high-pressure sodium lamps (250~400W) can reach 130~140 1m/W. High-power LED street lights mostly use 1W LED tubes. Theoretically, their luminous efficiency is similar to that of high-pressure sodium lamps. However, considering the three elements of ballast loss, lamp power and light channel utilization, and general considerations, LEDs are now more energy efficient than high-pressure sodium lamps. Lower. Low-power LED street lights (≤150W) save 10% energy than high-pressure sodium lamps.
