Abstract

The invention relates to an infrared light source with an adjustable outgoing angle. The infrared light source is characterized by comprising a cooling fan, a cooling fin, an integrated large-power infrared LED light source, a diffusion plate, a condensing cup, a condensing lens, a driving circuit and a shell, wherein the cooling fan is located at the bottom of the cooling fin and adopts blowing forced cooling; and the integrated large-power LED light source is mounted on the cooling fin, and the condensing cup and the condensing lens are mounted in front of the integrated large-power LED. Light rays emitted by the integrated large-power LED light source comprise paraxial parts and non-paraxial parts, the paraxial light rays are directly emitted through the condensing lens, and the non-paraxial light rays are collected by the condensing cup and are emitted after being converged to the condensing lens. According to the invention, by adopting the combination of the large-power integrated LED light source, the condensing cup and the condensing lens, light emitted by the integrated large-power infrared LED light source is effectively graded, the infrared light source with the adjustable outgoing angle is obtained, and the evenness of outgoing light is effectively improved.

Description

technical field [0001] The invention relates to the field of lighting, in particular to designing an infrared light source device for night vision monitoring. Background technique [0002] Infrared night vision technology is a kind of photoelectric technology that realizes night observation by means of photoelectric imaging devices. It is a night vision technology that realizes observation by actively illuminating and using the target to reflect infrared light. Rapid development; the corresponding equipment is infrared light source and infrared camera equipment. [0003] In the outdoor environment, in order to fill the light with a longer distance, the industry generally uses multiple in-line LED light sources for fill light. Due to the limitation of in-line LED performance, the effect is not ideal at long distances. And when the field of view is small, there is a problem of uneven light spots in the illumination of multiple LEDs. [0004] To sum up, the effect of the inf...
