the LED street lamp 【 LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Large-scale promotion, color temperature ( Light color) Become the focus of the industry. The speech by analyzing the physiological and psychological properties of color temperature, discuss it with bright, According to) Degree, the relationship between comfort, combined with the LED street lamp test, puts forward relevant to current color temperature range of the technical level of the LED street lamp.

from lighting perspective LED street lamps, lights, light distribution and light main failure, color temperature ( Light color) And so on four big problems. In recent years, LED street lamp technology, optical performance improve soon. From our recent organization LED street lamp test results, 27 LED street lamps in the existing six whole lighting effect of more than 70 lm/W, up to 81. 5 lm / W; Compared with light level is greatly improved, evenness and high pressure sodium lamp has advantage; Obviously improved droop problem, compared to other light sources are not inferior.

in this background, the color temperature problem surfaced, rise as one of the main contradiction of LED lights, has become the focus of the industry recently. Indeed, street lamp is night of city 'light', 'impression', the color temperature is determined by night is closely related to citizens' daily life. Therefore, the LED street light color temperature problem to be solved before scale application, or may become a big obstacle to promote. At present, this kind of situation has appeared in some cities, also will be fulfilled in more cities.

Wu Chunhai will be at the meeting through the analysis of the physiological and psychological properties of color temperature, discuss it with bright, According to) Degree, the relationship between comfort, combined with the LED street lamp test, puts forward relevant to current technical level of color temperature range.
