Description

Technical Field

[0001] The utility model relates to the technical field of light sources, in particular to an infrared plane opening light source. Background Art

[0002] Infrared light sources are widely used in non-dispersive infrared (NDIR) gas sensor modules. The black body radiation layer is heated by heating electrodes to emit broad-spectrum thermal radiation infrared light. After being filtered by infrared filters, infrared light of a specific wavelength is emitted. When passing through the gas to be measured, it is absorbed and attenuated. According to the Beer-Lambert law: I = I0·exp(-μCL), the concentration of the gas to be measured is calculated by comparing the light intensity before and after attenuation. Among them, I is the infrared light intensity reaching the detector when there is gas absorption, I0 is the infrared light intensity reaching the detector when there is no gas absorption, C is the gas concentration in the chamber, L is the chamber length or infrared light path, and μ is the gas absorption coefficient.

The utility model utilizes the LED light group in combination with the diffusion plate to achieve a high-uniform large-format light source; by installing a strip-shaped support plate at the upper end of the edges around the bottom plate, and installing a corresponding matching diffusion plate at the upper end of the support plate, since the support plate is an aluminum alloy profile, its structure is strong and the heat dissipation effect is good, so that the light source has strong stability; therefore, the utility model has the advantages of novel design, simple structure, achieving a high-uniform large-format light source, and improving the shooting effect of large-format products.
