Problems solved by technology

The light source with this structure will have two inherent defects: one is that the thermal radiation of the lamp and the thermal radiation of the power supply affect each other's thermal stability, thus affecting the luminous stability of the lamp; in addition, a fan is used in the same cavity to cool the lamp When connected to the power supply, the cooling air may not be smooth and affect the cooling effect
These two defects will affect the stability of the lamp and the power supply, thereby affecting the stability of the light emission of the lamp
In addition, the heat of the uninsulated external environment can affect the operation of the light source
[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention is suitable for material analysis light sources and provides a heat-stability light source. The heat-stability light source comprises a machine shell, a light output interface, a power source located in the machine shell and a light source body. A lamp cavity component, an air inlet pipe and an air outlet pipe are arranged in the machine shell. The light source body is fixed in a cavity of the lamp cavity component, and the lamp cavity component is connected with the light output interface. The air inlet pipe is connected with the lamp cavity component and a first air inlet formed in the machine shell. The air outlet pipe is connected with the lamp cavity component and a first air outlet formed in the machine shell. The first air outlet is provided with a fan. The air inlet pipe, the inner cavity of the lamp cavity component and the air outlet pipe are communicated and form an airflow passage. The machine shell is further provided with a second air inlet and a second air outlet provided with a fan. The second air inlet, the inner cavity of the machine shell and the second air outlet are communicated and form an airflow passage. The heat-stability light source has the characteristics that the double air passages are designed, so that the interplay between lamp heat radiation and power source heat radiation are effectively reduced, and the heat stability of the light source and the stability of light output are improved; in addition, heat in external environment is also isolated from the light source, so that the work of the light source is not influenced.

Description

technical field [0001] The invention relates to a light source for material analysis, and more specifically relates to a thermally stable light source for spectral analysis and measurement with the feature of double air duct heat insulation design. Background technique [0002] At present, light sources commonly used in spectral analysis on the market such as figure 1 As shown, a casing 101 , an optical output interface (such as an SMA905 optical fiber connector, etc.) 102 , a lamp 103 , a power supply 104 , a fan 105 , and an air inlet 106 . In this type of light source, the lamp 103 (such as tungsten lamp and deuterium tungsten lamp, etc.) and the power supply 104 are placed in a casing 101, and convection is used (by opening the air hole 106 on the casing to make the air flow naturally or using a fan 105 Realized) and thermal conduction (realized by using the case) cooling. The light source with this structure will have two inherent defects: one is that the thermal radi...
