Embodiment Construction

[0031] The purpose of this specific embodiment is to provide a method for improving the color rendering index of an LED light source module, and an LED light source module produced by this method, for the problems existing in the existing LED light source module. While having high color rendering index and high luminous efficacy, the group can also effectively reduce costs.

[0032] Through our latest research, it is found that a special type of white LED is compensated by a suitable red LED, and the manufactured LED light source module has a particularly outstanding ability to improve the color rendering index. Therefore, the basic idea of ​​this specific embodiment is to use a type of white LED with special specifications as the basic light source, and then use a red LED to perform spectral compensation in a certain proportion.

Abstract

An LED light source module and a method for improving the color rendering index of an LED light source. The method includes: S1) selecting or preparing a white LED and a red LED; S2) taking the white LED as a basic light source, utilizing the red LED to compensate the spectrum of the white LED, and constituting the LED light source module. The module includes a white LED and a red LED for compensating the spectrum of the white LED. The LED light source module has a simple structure and achieves a low cost for controlling the color rendering index.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED light source module and a method for improving the color rendering index of the LED light source module. Background technique [0002] As a new type of high-efficiency light source, LED is changing the way of human lighting with its advantages of low energy consumption and long life. However, the white light LED used as living lighting is subject to the constraints of current technology, and there are still many problems, which need to be continuously improved. The original white light LED is obtained by using a blue LED chip to emit blue light to excite a single phosphor to obtain a white light LED. Although this white light LED can obtain high luminous efficiency, it has obvious spectral missing phenomenon in some visible light bands, so its spectrum is a an intermittent spectrum. Due to the defect of missing spectrum, it is difficult for the color rendering index...
