Referring to fig. 8, the light source 3113 is generally cylindrical, and a light emitting surface 31131 is formed on an end surface of the light source 3113 remote from the substrate assembly 3111, and laser light is emitted from the light emitting surface 31131, and the light emitting surface 31131 faces the collimating element 3114. The light source 3113 is secured to the substrate assembly 3111, and in particular, the light source 3113 may be bonded to the substrate assembly 3111 by a sealant 3117, such as a side of the light source 3113 opposite the light emitting side 31131, bonded to the substrate assembly 3111. Referring to fig. 7 and 9, the side 31132 of the light source 3113 may be adhered to the substrate assembly 3111, the sealant 3117 may wrap around the side 31132, or only one surface of the side 31132 may be adhered to the substrate assembly 3111 or several surfaces may be adhered to the substrate assembly 3111. At this time, the sealant 3117 may be a heat conductive adhesive, so as to conduct heat generated by the operation of the light source 3113 into the substrate assembly 3111.

Referring to fig. 7, the diffractive optical element 3115 is carried on the top wall 31122 and is housed in the protective cover 3116. Opposite sides of the diffractive optical element 3115 respectively abut the protective cover 3116 and the top wall 31122, the baffle 31162 includes an abutting surface 31163 adjacent to the light-passing hole 31125, and the diffractive optical element 3115 abuts the abutting surface 31163.

Specifically, the diffractive optical element 3115 includes a diffraction entrance face 31152 and a diffraction exit face 31154 that are opposite. The diffractive optical element 3115 is carried on the top wall 31122, the diffractive exit face 31154 abuts a surface (abutting face 31163) of the baffle 31162 adjacent to the light-passing aperture 31125, and the diffractive entrance face 31152 abuts the top wall 362. The light through holes 31125 are aligned with the receiving cavity 31121 and the light exit through holes 31160 are aligned with the light through holes 31125. The top wall 31122, the annular side wall 31164 and the baffle 31162 interfere with the diffractive optical element 3115, thereby preventing the diffractive optical element 3115 from falling out of the protective cover 3116 in the light exit direction. In certain embodiments, the protective cover 3116 is adhered to the top wall 31122 by glue.

The light source 3113 of the laser projection module 311 adopts an edge-emitting laser, which has smaller temperature drift than the VCSEL array on one hand, and has a single-point light-emitting structure on the other hand, the edge-emitting laser does not need to be designed into an array structure, so that the manufacturing is simple, and the light source cost of the laser projection module 311 is lower.

When the laser of the distributed feedback laser propagates, the gain of the power is obtained through the feedback of the grating structure. To increase the power of the distributed feedback laser, it is necessary to increase the injection current and/or increase the length of the distributed feedback laser, and since increasing the injection current increases the power consumption of the distributed feedback laser and causes serious heat generation, in order to ensure that the distributed feedback laser can work normally, the length of the distributed feedback laser needs to be increased, which results in the distributed feedback laser generally having an elongated structure. When the light emitting surface 31131 of the edge emitting laser faces the collimating element 3114, the edge emitting laser is vertically placed, and since the edge emitting laser is in an elongated structure, the edge emitting laser is prone to falling, shifting or shaking and other accidents, and therefore the edge emitting laser can be fixed by the arrangement of the sealing glue 3117, and falling, shifting or shaking and other accidents of the edge emitting laser are prevented.

Referring to fig. 7 and 10, in some embodiments, the light source 3113 may also be secured to the substrate assembly 3111 using a securing arrangement as shown in fig. 10. Specifically, the laser projection module 311 includes a plurality of support blocks 3118, the support blocks 3118 may be fixed on the substrate assembly 3111, the plurality of support blocks 3118 collectively enclose the light source 3113, and the light source 3113 may be mounted directly between the plurality of support blocks 3118 when mounted. In one example, the plurality of support blocks 3118 collectively clamp the light source 3113 to further prevent the light source 3113 from rocking.

In some embodiments, the protective cover 3116 may be omitted, where the diffractive optical element 3115 may be disposed in the accommodating cavity 31121, the diffractive exit surface 31154 of the diffractive optical element 3115 may abut the top wall 31122, and the laser light passes through the diffractive optical element 3115 and then passes out of the light-transmitting aperture 31125. In this way, the diffractive optical element 3115 is not easily detached.

In some embodiments, the substrate 31111 may be omitted and the light source 3113 may be directly affixed to the circuit board 31112 to reduce the overall thickness of the laser projection module 311.
