LED light source module and packaging method thereof

Abstract

Disclosed are an LED light source module and a packaging method thereof. The LED light source module comprises a substrate, a first-level cold-white LED chip, a first-level red LED chip, a first-level green LED chip, a first-level blue LED chip, and a first-level warm-white LED chip, wherein the first-level cold-white LED chip, the first-level red LED chip, the first-level green LED chip, the first-level blue LED chip, and the first-level warm-white LED chip are all uniformly distributed on the substrate; the first-level cold-white LED chip is located in the middle of the substrate; and the first-level red LED chip, the first-level green LED chip, and the first-level blue LED chip are alternatively connected to form a first-level RGB color wheel structure, which is externally located on the first-level cold-white LED chip. The first-level warm-white LED chip is of a cyclic structure and is externally arranged on the RGB color wheel structure, and the first-level cold-white LED chip, the first-level RGB color wheel structure, and the first-level warm-white LED chip are coaxial. According to the invention, a light source endless belt composition benefits excellent color-mixing effect; the color temperature of the light source is accurate, continuous, and adjustable; color rendering of the light source is ensured; and light quality of high-saturated light color is obtained.

Description

technical field [0001] The invention relates to an LED light source component and a packaging method thereof. Background technique [0002] In commercial lighting, merchants expect to display products better through lighting. Relevant research shows that appropriately increasing the color saturation of objects can enhance consumers' desire to buy. NIST (National Institute of Standards and Technology) of the United States also proposed to use CQS (ColorQualityScale) color quality to evaluate the quality of the color of the light source, and selected 15 kinds of saturated colors as new color samples, and changed the sample color into a continuous partial saturated change , making color rendering measurements more accurate. High saturation light color light source is one of the trends of future lighting development. [0003] The existing LED light source has the following problems: the color quality is poor, although the light source with continuously adjustable color tempera...

AI Technical Summary

Problems solved by technology

[0003] The existing LED light source has the following problems: the color quality is poor, although the light source with continuously adjustable color temperature is obtained, the color rendering of the obtained light source is not ideal, which deviates from the expected effect; the light spot of the light source is uneven, and light and dark light spots appear Or color cast spot, light distribution curve is not ideal
