Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED packaging method, a packaging device, a light adjustment method and a system. Background technique [0002] Compared with traditional lighting sources, LED light-emitting devices have many significant advantages, such as lower power requirements, better driving characteristics, faster response speed, higher shock resistance, longer service life, green environmental protection, etc. Therefore, the market demand for LED light-emitting devices continues to grow, gradually replacing traditional lighting sources. [0003] For traditional white LED devices, the usual packaging method is to coat a single-color LED chip with a phosphor to mix light. This packaging light combination lacks the necessary light elements, resulting in low color rendering. In order to solve this problem, some people mix and coat several colors of phosphors on the single-color LED chip for light mixing. Al...

Problems solved by technology

[0003] For traditional white LED devices, the usual packaging method is to coat a single-color LED chip with a phosphor to mix light. This packaging light combination lacks the necessary light elements, resulting in low color rendering. In order to solve this problem, some people mix and coat several colors of phosphors on the single-color LED chip for light mixing. Although the color rendering is improved to a certain extent, the mixed coating of phosphors leads to a low light conversion rate. , the light uniformity is low. At the same time, the above packaging methods cannot realize the adjustment of the brightness, color rendering and color temperature of LED packaging devices.

For traditional color LED devices, it is usually achieved by directly using a single-color LED chip, or combining multiple single-color LED chips. The color LED device made of a single-color LED chip has a narrow spectral range. Changing the hue of other colors on the surface of the object can easily cause color imbalance and make people feel uncomfortable. Although the combination of multiple single-color LED chips can be adjusted through the dimming circuit, this The combination method cannot achieve a reasonable light mixing effect, and the spectral components are single or discontinuous
