It can be seen that the structure of the utility model is divided into an upper part and a lower part, wherein the lower part is a linear light source part, the strip-shaped base 11 is used as a supporting base, the strip-shaped lamp panel 12 is installed to form a strip-shaped light source, and a light gathering part is also arranged on the strip-shaped base 11 to gather the light emitted by the strip-shaped lamp panel 12 to form high-brightness light; on the top is a coaxial light source part, and it should be noted that in the present utility model, the light of the coaxial light source part originates from a linear light source, and the housing 21 of the coaxial light source part is covered at the end of the linear light source, so that the light can be emitted from the first light outlet 22 and the second light outlet 23.
The utility model adopts a bolt connection mode in connection and fixation between the linear light source and the coaxial light source. Specifically, the housing 21 of the coaxial light source is partially fastened to the outer side of the bar-shaped base 11, and then is fixed by bolting. When the linear light source is required to be used independently, the front shell 21 part is removed, and when the linear coaxial light source is required to be matched for detection, the shell 21 part is installed. Regarding the installation between the housing 21 and the base, besides the bolt fixing connection, the installation can also be performed by adopting a mode of fastening connection or matching connection of a boss and a chute, and the purpose of the installation is to facilitate the disassembly between the housing 21 and the bar-shaped base 11.
