Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a high-performance four-chip LED spectrum optimization technology method. Background technique [0002] Multi-chip LED (Multi-chips of LED or Multi-packages of LED) is an important type of white LED, but due to the inconsistent light attenuation of each single chip, it causes the problem of light color consistency, making it suitable for functional lighting applications It is not as extensive as PC LED (Phosphor converted LED), and at the same time, the advantage of multi-chip LED spectrum flexibility cannot be brought into play, which greatly limits its application. In addition, for the application of white LEDs, most of the research only focuses on the efficiency and color rendering performance of white LEDs, and it is not enough to focus on these properties. For example, some studies have shown that inappropriate spectral forms of light sources will cause health hazards. Ca...
