A) color space uniformity evaluation to evaluate the existence of LED lamps with different observation angle color differences.

The characteristics of a single emitter of a traditional light source are different, the LED lamp used by LED luminaire is composed of multiple emitters and glows, there is color difference between the emitters in the LED luminaire, and the spatial distribution of the color of the LED luminaire needs to be evaluated by using the color space uniformity evaluation.

b) Use life to evaluate the durability of LED luminaires. The measurement and evaluation of the life performance of traditional light source has been standardized and interchangeable, so the life of traditional light source lamps can meet the requirements by replacing the damaged light source and the control device of the lamp designed by the life of 10, so the life of the traditional light source lamp is generally not evaluated. LED lamps life and led their own life, led drivers and lamps provided to the LED environment and many other factors, and at present, there are more LED lamp forms, in addition to the LED with standard lamp head, other LED lamps do not have interchangeability, so for different LED lamps, Its life span can only be determined by the relevant life evaluation.

When evaluating the life of LED lamps, it is necessary to claim not only optical pass maintenance Life (LX), but also failure rate (FX). c) The evaluation parameters of the luminous flux ratio that can be used by luminaires are different from those of traditional lamps.

Traditional lighting lamps are evaluated with luminaire efficiency, while led luminaires use light efficiency evaluation. D) Unlike traditional lighting sources can be used alone photometric testing, photometric measurement can use the relative method, led light source on the temperature is extremely sensitive, not suitable for the LED light source from the luminaire separation out of the individual measurement, photometric measurement should be used absolute method to the luminaire as a whole photometric test.
