How the solar garden lights
4, LED street lamp light color than high pressure sodium lamp much higher, high pressure sodium lamp color rendering index is only 23 or so, and LED road lamp color rendering index of 75 or more, from the visual psychological point of view, to achieve the same brightness, LED lamp
And the luminous efficiency of high-pressure sodium lamp is increased with the power to increase, therefore, the overall effect of light-emitting LED lamp than the high pressure sodium lamp; (the overall light effect is theoretically, in fact more than 250W high pressure sodium lamp light efficiency than the LED
3, LED light source efficiency has now reached 90-110LM / W, but also a lot of room for development, the theoretical value of 250lm / W.
2, LED street lamp has a unique secondary optical design, the LED light will be light to the desired lighting area, to further improve the efficiency of light to achieve energy-saving purposes.
1, LED street lamp itself, the characteristics of light unidirectional, no light diffusion, to ensure the efficiency of light.
