A surface light source light guide color mixing structure and a lighting lamp with the light guide color mixing structure

Abstract

The invention provides a light guiding color mixing structure of an area source, and an illuminating lamp with the light guiding color mixing structure. The cost is low, the color and the brightness of a light source can be adjusted at the same time, high-efficiency, energy-saving and stable simulation of an illuminating light source in the solar spectrum at different times can be achieved, and the object of enabling eyes to be safe and feel comfortable is effectively achieved. The light guiding color mixing structure of the area source comprises low light sources and a light guiding structure, at least one low light source is integrated on the side surface of the light guiding structure, and each low light source is connected to a program control circuit structure.

[0002] Long-term evolution has made the human eye most adaptable to natural light (sunlight), but now widely used lighting sources, such as fluorescent lamps, electronic energy-saving lamps, and LED lights, have different spectra from natural light, and some lights are very bright and white, which is particularly dazzling , some so-called three primary color light sources are actually only similar in color. Many LED light sources feel very bright but the chromaticity is very uncomfortable; will change, the above-mentioned light sources cannot simulate the natural light that is comfortable for the human eye, and work and live in this light source environment for a long time, the color perceived by the human eye is obviously distorted, and the eyes are prone to fatigue and damage

[0003] For example, in the radiation calibration of optical remote sensors, the light source used in calibration in the past was a halogen lamp. Although the halogen lamp has a rich spectrum and stable color temperature, it is a thermal light source with high power consumption. It is easily damaged after being opened and closed many times. Heat also leads to an increase in equipment maintenance costs, and an ideal light source can be adjusted in color according to people's needs, but the spectrum of halogen lamps is fixed, it is difficult to achieve adjustable spectrum, and cannot match the real solar spectrum, and The general adjustable light sources on the market can only simply adjust the brightness or change the color, and cannot adjust the color and brightness at the same time, so it is impossible to simulate the lighting source of the solar spectrum in various environments and at different times.
