LED floor lamp and the difference between traditional lights
At present, LED floor lamps and traditional light source lamps on the performance, evaluation and design there are many different places.
1. Color space uniformity evaluation to evaluate the presence of LED lamps at different viewing angle color differences.
Traditional light source of a single light different characteristics of the LED lamps used in the LED lights are composed of multiple luminous body and light, LED floor lamp in the light between the color difference between the need to use color space uniformity evaluation to evaluate the LED lighting color The spatial distribution of the situation.
2. Evaluation of the durability of LED lamps with life.
The life and performance of traditional light sources has been standardized and interchangeable. Therefore, the life of traditional light source lamps can meet the requirements by replacing the damaged light source and the lamp control device designed for 10 years. The life of traditional light source lamps. LED lamp life and LED life itself, led drivers and lighting provided to the LED environment and many other factors, and the current LED floor lamp form more, in addition to the standard lamp with LED floor lamp, the other LED lights do not have interchangeability, so For different LED floor lamps, its life can only be determined by the relevant life evaluation. In the evaluation of LED lamp life, not only to claim the luminous maintenance life (LX), but also claimed failure rate (FX).
3. Lamps can be used in the luminous flux ratio of the evaluation parameters and traditional lamps are different. The traditional lighting fixtures with lamp efficiency to evaluate, and LED lighting use of light evaluation.
4. Do not like the traditional light source can be a separate photometric test, photometric measurement can use the relative method, led light source is extremely sensitive to the temperature, not suitable for LED floor lamp light source separated from the lamp separately measured, photometric measurement should be used absolutely The luminosity of the fixture as a whole.
