Plane light source and plane light source device for realizing various standard spectrums and spectral data monitoring

Abstract

The invention discloses a plane light source for realizing various standard spectrums and spectral data monitoring. The plane light source sequentially comprises an outer frame, a front diffusion plate, a light guide plate, a rear diffusion plate, an outer bottom plate and an outer cover plate from top to bottom; a plurality of points are carved on the front face and the back face of the light guide plate and used for reflecting and evenly mixing light emitted by the LED lamp beads; side light bars are arranged on the four sides of the light guide plate, and a plurality of types of LED lamp beads needed for achieving standard light are integrated on the side light bars; and a projection hole of the micro spectrometer is formed in the outer bottom plate, and the micro spectrometer is installed on the outer cover plate, located on the side edge of the light-emitting face of the light source and used for reading and monitoring spectral data in real time. The invention further discloses aplane light source device for realizing various standard spectrums and spectral data monitoring. According to the invention, various light source spectrums (A light, D50 and D65) meeting the CIE standard can be obtained, the actual color temperature, illumination and spectral data of the light source can be monitored in real time, and the accuracy is high.

Description

technical field [0001] The invention relates to the field of light sources, in particular to a planar light source and a device thereof for realizing monitoring of various standard spectra and spectral data. Background technique [0002] Light sources are generally divided into two types: natural light sources and artificial light sources. The former mainly refers to sunlight, and the latter mainly refers to light sources manufactured according to the spectrum of sunlight. It is known that the wavelength of the sunlight spectrum is approximately from ultraviolet light of 300nm to infrared light of 2600nm, wherein the wavelength of visible light is approximately between 380nm and 780nm. At the same time, the visible light spectrum is also commonly known as the visible full spectrum. [0003] In modern industry, all walks of life need to identify the color of products. The color standard is based on natural light, but affected by time, climate, season, latitude and other fact...
