2. LED street lamp has a unique secondary optical design, which irradiates the light of LED street lamp to the required lighting area, further improving the lighting efficiency, so as to achieve the purpose of energy saving.
3, LED has reached 110-130lm/W, and there is a lot of space for development, the theoretical value of 360lm/W. The luminous efficiency of high-pressure sodium lamp is increased with the increase of power, therefore, the overall light efficiency of LED street lamp is stronger than the high-pressure sodium lamp; (This overall light efficiency is theoretical, in fact, above 250W high pressure sodium lamp light efficiency is higher than LED lamp).
4, LED street light color is much higher than high pressure sodium lamp, high pressure sodium lamp color index is only about 23, and LED street light color index is more than 75, from the perspective of visual psychology, to the same brightness, LED street light illuminance can be reduced by more than 20% than the average high pressure sodium lamp.
