Abstract

The invention discloses a high-color-rendering white-light LED lamp structure which comprises a support and blue-light LED light sources. The support is provided with a light-emitting face, and the blue-light LED light sources are mounted and arranged along the light-emitting face. The light-emitting face is separated into a red-light chamber and a green-light chamber through two wedge-shaped circumferential walls, and the red-light chamber and the green-light chamber constitute a light-emitting unit emitting light towards the same side. The surface of the blue-light LED light source located in the red-light chamber is coated with red fluorescent powder, and the surface of the blue-light LED light source located in the green-light chamber is coated with green fluorescent powder. The red-light chamber and the green-light chamber form different light-emitting angles through the wedge-shaped circumferential walls, and the light-emitting angles of the red-light chamber and the green-lightchamber are mutually overlapped. According to the high-color-rendering white-light LED lamp structure provided by the invention, the color-rendering index is not obtained through adjusting of the fluorescent powder proportion, thus the light effect of blue LED chips cannot be greatly influenced, and the high color-rendering index and the high light effect are ensured.

Description

technical field [0001] The invention relates to an LED lamp structure, in particular to a high color rendering white LED lamp structure. Background technique [0002] As we all know, white light in nature is composed of a complete spectrum, and white LED lights need to simulate and restore the natural light spectrum through a combination of light sources or phosphors of various colors, and the degree of reduction of the spectrum also determines the color rendering of the light source product. index. Existing mainstream white LED lamps usually use blue LED chips to excite yellow phosphors to produce white light, and adjust the concentration of red phosphors to improve the color rendering index. This light source structure sacrifices part of the LED lighting effect while obtaining a high color rendering index. Under the same packaging conditions, the color rendering index is increased from 80 to 90, and the light efficiency of the LED lamp is reduced by about 15%. Light sour...
