Problems solved by technology

[0002] The existing laser module is composed of a front housing with a focusing lens and a rear housing with the laser diode. Usually, an image lens is arranged between the front housing and the rear housing through the The light beam projected by the laser diode has a specific pattern, but it cannot effectively prevent water vapor from intruding into the laser module, which often causes foggy water vapor in the image lens, which greatly reduces the use efficiency of the laser module, and even more and cannot effectively detect the temperature generated when the laser diode is working

Embodiment Construction

[0039] In order to describe the laser module proposed by the present invention more clearly, it will be described in detail below with reference to the drawings.

[0040] see figure 1 , Figure 2A , Figure 2B , Figure 2C As shown, wherein, the laser module 1 is connected to a circuit board 2, which includes: a cylindrical body 11, a focusing lens 12, a laser diode 13, a housing 14, an airtight structure 15, a temperature The sensing element 16 , a temperature control board 17 , and an image lens 9 . The main body 11 further includes: a front open end 111 , a rear open end 112 , and an inner wall 113 . A concave step 1131 is formed on the inner wall 113 adjacent to the front opening 111 . The airtight structure 15 is used to prevent outside moisture from intruding into the laser module 1, thereby affecting the projection effect of the image lens 9, and it further includes: a pressure ring 151, a plurality of sealing rubber rings 152, And a seal glue 153. In the first p...

Abstract

Provided is a laser module which is connected to a circuit board. The laser module comprises a main body, a focusing lens, a housing, a laser diode, an image lens and an airtight structure. The main body comprises a front opening end, a rear opening end and an inner wall. The focusing lens is combined in the front opening end of the main body. The housing coats the external of the main body. A through hole is arranged at one end of the housing at a position that corresponds to the focusing lens, while the other end of the housing is provided with an opening which allows the main body to extend into the housing. The laser diode is combined with the inner wall of the main body by packing through the rear opening end of the main body and corresponds to the focusing lens. The laser diode is further electrically connected to the circuit board. The image lens is arranged inside the through hole and corresponds to the focusing lens. The airtight structure is used to enclose the image lens inside the housing.

Description

technical field [0001] The invention relates to a laser module, in particular to a laser module which uses an airtight structure to seal an image mirror in the laser module to become a waterproof and moisture-proof laser module. Background technique [0002] The existing laser module is composed of a front housing with a focusing lens and a rear housing with the laser diode. Usually, an image lens is arranged between the front housing and the rear housing through the The light beam projected by the laser diode has a specific pattern, but it cannot effectively prevent water vapor from intruding into the laser module, which often causes the image lens to produce foggy water vapor, which greatly reduces the use efficiency of the laser module, and even more And the temperature generated when the laser diode is working cannot be effectively detected. [0003] Therefore, the present invention uses an airtight structure to seal and combine the front housing and the rear housing to...
