Light emitting diode (LED) white lamp with red light chip

Abstract

The invention relates to a light emitting diode (LED) white lamp with a red light chip and mainly solves the problems of single light spectrum, poor colour rendering and poorer light quality because a white light of the conventional LED white lamp is formed by mixing a blue light and a yellow light. The LED white lamp with the red light chip comprises a circuit board, wherein a light-shading part is arranged on the circuit board; a circular hole is formed in the middle of the light-shading part; a blue light chip which is connected with the circuit board is arranged at the bottom of the circular hole; and the red light chip is also arranged at the bottom of the circular hole. The LED white lamp with the red light chip has the advantages that: the red light chip is added into the conventional white lamp which has only the blue light chip; the colour rendering property of the LED white light is improved, so light spectrum components of the white light are relatively rich, the white light is more approximate to a natural light, and the light spectrum is almost a continuous light spectrum; and the LED white lamp can be applied to lighting of fields with high colour-rendering requirement on a light source such as a cafe, an evening party and a hotel.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an LED white lamp with a red chip and good color rendering. Background technique [0002] Because the traditional LED white light uses the blue light chip to excite the phosphor to produce yellow light or yellow-green light, so that blue light and yellow light or yellow-green light are mixed in a certain proportion to produce white light. This white light only contains blue light and yellow light or yellow-green light. The color is poor, the color rendering index is only about 70-75, and the light quality is poor. This kind of light source can only be used in general lighting occasions, and cannot be used in places that require high quality light, such as coffee shops and evening parties Site lighting, hotel lighting, medical lighting, camera lighting and other scenes that require high color rendering of the light source. For example, the authorized announcement number is CN201100557Y,...
