Therefore, the support 106 is only used to support the first filament 101 and the second filament 101. Two filaments 102. Specifically, one support 106 can support multiple first filaments 101 and multiple second filaments 102 , and one support 106 can also support one first filament 101 or one second filament 102 .

In this embodiment, the number of the first filament 101 is four, and the number of the second filament 102 is four as an example for schematic illustration. In fact, the first filament 101 and the second filament in the infrared light source The number of the two filaments 102 is not limited, and can be designed according to actual needs.

In one embodiment, the range of the gap between adjacent first filaments 101 and second filaments 102 is greater than 6 millimeters and less than 15 millimeters. The significance of selecting the gap between the first filaments 101 and second filaments 102 is: if The gap between the first filament 101 and the second filament 102 is greater than 15 mm, so that the unheated cold area between the first filament 101 and the second filament 102 is relatively large, which is not conducive to improving the uniformity of heating of the infrared light source; If the gap between the first filament 101 and the second filament 102 is less than 6 mm, it will be more difficult to manufacture.
