Abstract

it's a new type of infrared radiation source, which involves an infrared radiation source. The objective of the invention is to solve the problem that the heat dissipation of the current infrared LED has certain defects. it is largely affected by the temperature, the bandwidth of the light source is small, the temperature control system of the black body is complicated, and the light source of the halogen tungsten lamp has a narrow bandwidth. A new type of infrared radiation source includes a light source base, a pin sintered groove, a light source pin, a heating wire, an insulation coating, a protective coating, and a fixing wire. Advantages: First, it uses infrared heat radiation as the light mechanism and inputs a fixed current through the light source to obtain broadband infrared spectrum. Second, with insulation coating and protective coating, it has the function of heat preservation and shaping; Fixed wires are welded to the pin which has increased the anti- seismic performance of the light source; Fourth, it has a compact structure and low power consumption. it's also easy to realize production. The invention is mainly used for preparing infrared radiation sources.

Description

technical field [0001] The invention relates to a source of infrared radiation. Background technique [0002] Due to the absorption of infrared radiation by the atmosphere, it can be characterized by discrete bands composed of overlapping spectral lines of various intensities, the degree of overlap depends on the half-width of the spectral lines, and the distribution of these spectral lines throughout the absorption band depends on the absorption Molecules, because of different absorption bands, most gases in the atmosphere have absorption peaks in the infrared band, such as carbon monoxide has an absorption band at 4.8 μm; carbon dioxide has three strong absorption bands at 2.7 μm, 4.3 μm and 15 μm; water Vapor, ozone, nitric oxide, methane, etc. all have absorption bands. According to this absorption band, select the corresponding infrared radiation source to form a gas sensor. This type of sensor is called NDIR. Compared with electrochemical sensors, this type of sensor ...
