What power LED street lights are commonly used in China and how long is their life?

As a new way of road lighting, led street lights not only save energy, but also enhance the image of the local night. Because of its high brightness, it is more convenient for people to travel at night.

The specific power of the led street light needs to be determined according to the specific conditions of the road. The street light poles of different heights use different powers, just like the meter adopts the lamp between W~W, the meter adopts the lamp between W~W, and the professional LED street lamp The manufacturer will give a plan that meets the standard after surveying the road conditions.

The theoretical life of led light sources is very long, but the overall life of a lamp is not simply the life of the light source. The lamp also includes the influence of the driver and the lens. Therefore, the life of the street lamp should be limited to the shortest life of all lamp components. At present, the lifespan of the good driving power supply and the lens made of silicon material can reach hours.

This part of power saving. Take the LED lamp of w instead of the high-pressure sodium lamp of w as an example. The actual power of the high-pressure sodium lamp needs to be multiplied by the coefficient of the ballast, calculated by. The actual power is .w. There are also reactive power losses, line losses, transformer losses, etc. on the entire lamp circuit, which will not be added here, only the lower value in theory is compared. The entire lamp power of the LED u003d the power of the light source + the power loss, and the driving efficiency of the LEDs of good manufacturers can reach about %, which is almost negligible. Taking a street lamp lighting h as an example, the daily power consumption of the high-pressure sodium lamp u003d.*/*u003ddegrees. LED daily power consumptionu003d*/*u003ddegrees. If you add the intelligent dimming of LED street lights, the overall energy saving rate is at least more than %.

Generally speaking, LED street lights have higher brightness than traditional high-pressure sodium lamps of the same power. When configuring LED light sources, they cannot be configured according to the old concept. At the same time, it saves electricity and energy more than high-pressure sodium lamps, although at present, the price of led street lamps is higher.
