LED street lamp production and promotion in the future

With the speeding up of urbanization process, the LED street light has entered people's field of vision. Manufacturer of LED lights ED street lamp light is higher than high pressure sodium lamp many color, high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can, on average, more than 20% lower than the high-pressure sodium lamp. LED street light along with the rapid growth of the national economy, the contradiction between supply and demand of energy in our country, start there is a serious shortage of electricity supply situation, saving energy that is an urgent need to solve the problem. Therefore, the development of new type of high efficiency, energy saving, long life, high color rendering index, environmental protection of the LED street lamp for city lighting energy saving is of great significance. Now, LED street light can be seen everywhere in big cities, dotted with the night sky of the city. However, due to its own limitations, it has not been fully utilized. In order to ensure that the LED street lamp in our life play a more important role, we should be in the future research, production and promotion to solve these problems. First of all, the shape of the light structure is a problem. The shape of the traditional street lamps and small street lamp shape basic same, generally divided into two parts, light source and electrical appliances, and even some enterprises in indoor standard applied to outdoor lamps. Second: there was a problem with the connection between the leds and light. At present, almost all of the LED lights are fixed by screws, there are few coupling bolt. Therefore, there is a big hidden trouble to the safe operation of lamps and lanterns. The limitation of the LED street lamp itself constrains the development of the third part: the variability of lamps and lanterns component. LED street lamp components generally have LED chip, the power supply ( Drive) And the shell parts of lamps and lanterns. Main part is power and chip. In general, the LED chip cannot be replaced by electronic radiator, power supply ( Drive) Can also be replaced. However, there are many products is not convenient to replace power supply ( Drive) 。 Change is too time consuming. It is well known that the LED life can reach 30000 to 50000 hours. If the LED chip can't change, it means that replaced the lamps and lanterns can cause waste. Four is power supply ( Drive) Life. Power supply ( Drive) Is the key components of the LED lights. But at present, the market generally only guarantee the quality of the LED chip, and the power supply ( Drive) Life is another matter. General manufacturers committed to provide two years warranty. In the end, the development of LED street lamp met a new bottleneck - — Power supply ( Drive) Quality cannot be guaranteed, restricting the development of LED street light. LED street lamp power saving effect. In theory, the LED street lamp in practice is not more effective than high pressure sodium lamp. On the premise of lighting quality standards, high pressure sodium lamp high-power lamp ( 250×400 W) Theory of up to 130 x 1401 m. W, the light efficiency of high power LED street lamp and high pressure sodium lamp basic same, but considering the ballast loss, light utilization efficiency and light road, LED energy efficiency under high pressure sodium lamp. Low power LED street light, ≤150 W) 10% energy saving than the high-pressure sodium lamp.
