Abstract

The invention discloses a multi-color LED module manufacturing method. The method comprises the steps the steps that (1) a LED chipset is mounted on a substrate, wherein the LED chipset comprises a number of LED chips; (2) phosphor layers of different colors are coated on different LED chips; and (3) a light-transmitting layer is coated on the LED chipset processed in the step (2). According to the invention, the phosphors layers of many colors can be coated to realize the effect of multi-color luminescence; the luminescence effect of the LED chips is improved; and light spots are avoided.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a method for manufacturing a multi-color LED module. Background technique [0002] The existing multi-color LED module manufacturing method is generally to respectively mount the LED white light device and the LED chip coated with phosphor powder on the substrate, and then pot the fluorescent colloid as a whole. like figure 1 The multi-color LED module shown in the prior art has cumbersome processing technology, numerous procedures, low production efficiency and high cost. The white light device itself is a packaged product. After being mounted into a module, the overall light output density is not high, the light output efficiency and illuminance are low, the color mixing is uneven, and there are spots. It is difficult to apply to high-demand lighting occasions. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Contents of ...
