LED street light

Guide: How about LED street lights, everyone must pay attention to when they go home from work. Now the LED street lights on the roadside are getting more and more beautiful, and they are getting more and more beautiful. The white light hits the road and presents a soft beauty. LED street lights are different from ordinary street lights. What are the specific parameters of LEDs? Can you use such LED lights at home? If you want to know how LED street lights are, follow them along with Xiaobian!

How about LED street lights?

LED street light refers to street lamps made with LED lamps. How about LED street lamps, it has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index, etc. It is of great significance for urban lighting energy saving. LED street light is different from conventional street light. LED light source is low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow. It is efficient, safe, energy-saving, environmentally friendly, long life and fast response. The unique advantages of high color rendering index can be widely applied to roads. The cover can be made with high temperature resistance up to 135 degrees and low temperature resistance up to -45 degrees.

LED street light is different from ordinary street light

LED street light is different from ordinary street light. LED street light is led light bulb. The current is directly generated by the pn junction, and the energy loss is the least. The ordinary street lamp generally uses high-pressure sodium lamp, high-pressure gas discharge lamp, one more process than led, and the direction of the light source. Can not be oriented, radiating to the surrounding, so the energy loss is relatively large, the power consumption is different, LED street lights are more expensive than ordinary street lights, but the cost performance is better. Durable time is also relatively long. In terms of quality, LED is more practical. At the same power, the LED will be brighter and less lossy, so the power will be used less, saving more power than ordinary street lights, which means that LED street lights will save more money.

What are the disadvantages of LED street lights?

LED street light

1. Single LED power is low. In order to obtain high power, multiple parallel connections are required.

2, low color rendering. The color displayed under the LED illumination is not as true as the incandescent lamp, which is analyzed from the spectral distribution and is a technical problem.

3, light spots. Due to defects in the manufacturing process of the white LED itself and the matching error with the reflective cup or lens, the "yellow circle" problem is easily caused.

4, LED illumination uniformity problem. If the secondary optical design is not carried out, the illumination of the LED is relatively concentrated, so the secondary optical design must be carried out so that the light intensity distribution map is bat-shaped.

5, LED light fade problem. Compared to low-power LEDs, the light decay of high-power LED street lights is much better. However, low-power LED heat dissipation is small. The high-power LED is a problem that there is no way to solve the problem of heat dissipation, and the brightness will be significantly reduced after heating, so the power cannot be made large. The largest Spark LED street light sold in the market is 360W.
