Three key technology of LED panel lights

Light performance: the optical performance of the LED panel lights are mainly related to luminosity, spectral and color and other aspects of performance requirements. According to the latest industry standard "semiconductor light-emitting diode test method", the main emission peak wavelength, spectral radiation bandwidth axial luminous intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity and dominant wavelength, color rendering index and other parameters. LED panel lights commonly used white LED, color temperature, color rendering index and illuminance is particularly important, it is an important indicator of the atmosphere and lighting effects, and color purity and dominant wavelength is generally not required.


LED mainstream practice within the industry is later packaged LED chip light source or light source module is formed in the lamps made when further light, this approach is used in the existing traditional light sources, because the traditional light source is a 360 ° light. If you want the light guide to the application end, Philips is currently the best of a traditional lamp to do, loss of light has reached 40%. The lamp optical parameters of our many domestic manufacturers of LED panel light applications are in fact the optical parameters of the chip or the light source, instead of the optical parameters of the overall lighting of the indicators.

How to better improve the performance of light, it is the world's latest technology in the chip package to do with light, a light guide out of the chip, to maintain maximum light output, so that light loss rate of only 5% -10%. As technology continues to improve, more and more light loss rate will be low, the light source efficiency will be higher. Also with such a light source lamp without having to do with light, relative lamp efficiency will be
