The invention provides a lighting module with adjustable color temperature. The lighting module includes a color temperature light source and an adjustment light source group. The color temperature light source includes a first color temperature point with discontinuous color temperature on a Planck blackbody radiation curve. The lighting module adjusts a brightness ratio of the color temperaturelight source to the adjustment light source group by taking the first color temperature point as a reference so as to obtain a mixed light source. The mixed light source includes a second color temperature point and a third color temperature point which are located on the two sides of the first color temperature point. The second color temperature point and the third color temperature point are both on the Planck blackbody radiation curve. The lighting module with adjustable color temperature and the color temperature adjustment method of the same solve the technical problem of partial spectral loss caused by a process problem of an LED lamp.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to a lighting module with adjustable color temperature and a method for adjusting the color temperature of the lighting module. Background technique [0002] With its advantages of environmental protection, energy saving and long life, LED lights have gradually replaced traditional light sources such as incandescent lamps and halogen lamps with high energy consumption and short life in most lighting fields. For conventional LED lights, blue light chips generally excite yellow-red phosphors to emit light. However, due to technological conditions and other issues, the spectrum of LED lights will lack part of the spectrum compared to the real solar spectrum, and it is on the Planck black body radiation curve. , the color temperature points of LED lights are not continuous, and the human body adapts to activities in the solar spectrum environment, such as the sun spectrum environment i...
