LED (light-emitting diode) spotlight capable of improving color rendering index through adjusting

Abstract

The invention provides an LED (light-emitting diode) spotlight capable of improving the color rendering index through adjusting. The LED spotlight comprises a circuit board, a light source module, a lamp cover for light distribution, a high heat conduction device, a radiator and a control circuit for controlling the color rendering index of a light source module, wherein the light source module is arranged on the circuit board; the circuit board is connected with a radiator, the radiator is provided with the high heat conduction device, and the light source module comprises a white light source module and a red light source module; the control circuit comprises a main light source circuit for controlling the white light source module and a secondary light source circuit for controlling the red light source module. The LED spotlight provided by the invention has the advantages of being capable of emitting warm color light and providing high color rendering, meanwhile, the defects such as low efficiency and high heating value of the traditional lamp are overcome, and the LED spotlight belongs to a lamp product which is energy-saving and environment-friendly, and has high color rendering index.

Description

technical field [0001] The invention relates to an LED spotlight which can adjust and improve the color rendering index. Background technique [0002] The color rendering ability of a light source to an object is called color rendering, which is a comparison of the appearance color of an object with a reference or reference light source of the same color temperature, incandescent lamp or painting light. The spectral content of the light emitted determines the light color of the light source, but the same light color can be formed by many, a few or even only two monochromatic light waves, and the color rendering of each color is also very different. Light sources with the same light color will have different spectral compositions, and light sources with wider spectral compositions are more likely to provide better color rendering quality. When there is little or no main wave reflected by the object under the reference light source in the light source spectrum, the col...
