Problems solved by technology

[0005] Since COB packaged LEDs are mainly used for lighting, they have the highest sensitivity to color temperature, and the COB light source has a large area, resulting in uneven coating of phosphor powder, resulting in large differences in color temperature of the same batch of light sources.

Therefore, it is generally necessary to detect the color temperature and luminous flux of each COB-packaged LED in real time during the production process. If the color temperature is unreasonable, it is necessary to replenish the powder (add phosphor powder) in real time, and the color temperature can only be shipped out of the factory within an appropriate tolerance range. The packaging itself has different dimensions and needs to be adapted to different fixtures, which brings difficulties to the powder replenishment and testing. Therefore, unlike the traditional LED spectrometer, the COB package LED technology requires a new type of LED testing equipment to detect the COB package.
