Problems solved by technology

[0005] However, due to problems such as errors in the manufacturing process of light-emitting diodes, there is still a problem that the light-emitting wavelength is not easy to be controlled. It complies with the lighting regulations, and the color of the light is closer to the Planck curve, which is one of the current important topics

Abstract

The invention discloses a light-emitting device comprising a base plate, a light-emitting unit and a first color temperature adjusting light-emitting unit, wherein the light-emitting unit and the first color temperature adjusting light-emitting unit are respectively arranged on the base plate. The light-emitting unit emits a first light ray, and the first color temperature adjusting light-emitting unit emits a first color temperature adjusting light ray. The first light ray and the first color temperature adjusting light ray are synthesized to generate a first synthetic light ray, and the color temperature of the first synthetic light ray is in a color temperature error allowable range on a chromaticity coordinate.

Description

【Technical field】 [0001] The invention relates to a light emitting device, in particular to a light emitting device using a light emitting diode as a light emitting element. 【Background technique】 [0002] Because light-emitting diodes (Light-Emitting Diode, LED) have quite a lot of advantages, such as no warm-up time (idling time), fast response (about 10-9 seconds), small size, power saving, long life and low pollution , and with the substantial improvement of epitaxy and packaging technology, light-emitting diodes are easily made into extremely small or array-type components to meet the needs of applications, such as automobiles, communications industries, computers, traffic signs and displays, etc. field. Therefore, light-emitting diodes gradually replace cold-cathode tubes, incandescent lamps and fluorescent lamps, and become the most popular light-emitting components at present. [0003] At present, the light source used for lighting is mainly white light-emitting di...
