[0030] Example 1

[0031] like Figure 1 As shown, the laser source housing provided by this utility model is used to install the laser source, and the laser source can generate laser light when it is working.

[0032] Specifically, the outer casing includes a box body 210 and a box cover 220. The box body 210 is roughly rectangular in shape with an open top. The top of the box body 210 has an open opening, which is roughly rectangular in shape. The shape and area of ​​the open opening are set so that the laser light source can pass through.

[0033] The housing 210 has a certain depth, and the lid 220 covers the opening. The housing 210 and lid 220 form a cavity for accommodating the laser source. The lid 220 is light-transmitting. "Light-transmitting" means that the material does not absorb the laser light emitted by the laser source (light in the wavelength range of the laser), allowing stray light (10+% of the light emitted by the laser source is stray light) to pass through the light-transmitting material and reach the outside of the lid 220, thereby reducing the thermal load on the housing 210. Stray light generated by the laser source during operation can be transmitted through the light-transmitting lid 220, preventing it from accumulating inside the housing 210.

[0034] The box body 210 is made of a highly reflective material, or the inner wall of the box body 210 is provided with a highly reflective film, such as a gold-plated film. The bottom surface of the box cover 220 is provided with an anti-reflective film, which can make more stray light reflect towards the box cover 220 and then pass out from the box cover 220.

[0035] The material used to prepare the lid 220 includes an antistatic agent or a nano-active agent, or both an antistatic agent and a nano-active agent. Alternatively, a dustproof film is provided on the top surface of the lid 220, and the dustproof film is transparent to light. Or, a micro-nano structure with dustproof function is etched on the top surface of the lid 220. By setting the above-mentioned dustproof structure, dust adhesion is reduced. With less dust adhering, dust accumulation on the lid can be avoided.

[0036] In the field of surface dust prevention, the use of antistatic agents or nano-active agents, dustproof films, and micro / nano structures are all existing technologies.

[0037] Example 2

[0038] like Figure 2 As shown, the difference from Embodiment 1 is that the lid 220 has an upward protrusion 221. The area below the protrusion 221 is the main area where stray light is generated. The protrusion 221 can be strip-shaped and extends along the length of the lid 220. The protrusion 221 is integrally formed with the lid 220. The stray light transmitted from bottom to top into the lid 220 can enter the protrusion 221 and then be repeatedly reflected between the left and right side walls of the protrusion 221 before being transmitted out, thus preventing the stray light from being reflected back into the box body 210 by the outer wall of the lid 220.

[0039] In one embodiment, the protrusion 221 is disposed on the top of the light-dense region; wherein the light-dense region includes, but is not limited to, the main optical path and the chip.

[0040] Example 3

[0041] like Figure 3 As shown, the difference from Embodiment 1 is that the top surface of the cover 220 is inclined relative to the horizontal plane, and the inclination direction is towards the cooling fan 400. The cover 220 can be set to be entirely inclined relative to the horizontal plane, or only the top surface of the cover 220 can be inclined, i.e., the longitudinal section of the cover 220 is wedge-shaped. The airflow from the cooling fan 400, used for cooling the laser 200, blowing horizontally is blocked by the inclined top surface of the cover 220, resulting in a larger surface area for airflow to reach dust on the top surface of the cover 220, making it easier for the dust to be blown away.

[0042] The cooling fan 400 is located outside the laser source housing and is used to dissipate heat from the laser source housing.

[0043] Specifically, the top surface of the cover 220 is inclined relative to the horizontal plane, and the inclination direction is towards the cooling fan 400. This can be achieved by the following: the height of the horizontal plane where the first side of the top surface is located is lower than the height of the horizontal plane where the second side of the top surface is located; wherein, the first side of the top surface is the side of the top surface closer to the cooling fan 400, and the second side of the top surface is the side of the top surface away from the cooling fan 400.

[0044] The laser 200 provided by this utility model includes the aforementioned laser source housing. Because the laser 200 provided by this utility model incorporates the aforementioned laser source housing, it also possesses the advantages of a laser source housing.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
