Abstract

The invention discloses a far infrared light source based on a carbon fiber and a preparation method, relating to an infrared technique. The infrared light source comprises a pipe base, a pipe foot, a parabolic reflecting cup, an optical window and an infrared light source chip. The pipe foot is located on the upper surface of the pipe base, the parabolic reflecting cup is fixedly connected on the upper surface of the pipe base, and the front end of the parabolic reflecting cup is fixedly connected with the optical window; the infrared light source chip is fixedly connected on the upper surface of the pipe base and located at the focus of the parabolic reflecting cup, wherein the infrared light source chip comprises a supporting framework, a carbon fiber heating body and an electrode pressure welding block. The upper surface of the supporting framework is fixedly connected with the electrode pressure welding block; the carbon fiber heating body is integrally aligned at the upper part of a through hole of the supporting framework, and both ends of the carbon fiber heating body are respectively contacted with the electrode pressure welding block; the electrode pressure welding block is connected with the pipe foot through a pressure welding metal wire. The far infrared light source based on the carbon fiber is small in volume, low in power consumption and high in modulating frequency and middle and far infrared emitting efficiency. The preparation method can realize the preparation with low cost and large volume.

Description

Technical field [0001] The invention relates to the field of infrared technology, in particular to a carbon fiber-based infrared light source and a preparation method. Background technique [0002] Infrared technology has been widely used in fire alarm, vehicle, personnel detection, CO 2 , CH 4 And other aspects of gas detection and temperature measurement. [0003] A broad-band infrared light source that is currently widely used uses a heated spiral metal filament (mostly nickel-chromium wire) to emit infrared light. Adding infrared radiation materials such as ceramics to the spiral filament can improve the luminous efficiency of the light source. However, this kind of light source consumes a lot of power, emits uneven infrared light, and has a short life span. These traditional infrared light sources have large heat capacity and low modulation frequency due to the large heat capacity of the heating element (filament). In many occasions, more complicated mechanical chopper devic...
