Detailed Description

The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1-4, the laser module of the present invention includes a bracket 2 and a circuit board 1, wherein a protrusion and a fixing post are disposed on the lower portion of the bracket 2, and a groove and a fixing hole are correspondingly formed on the circuit board 1. The bracket 2 is fixedly connected with the groove and the fixing hole on the circuit board 1 through the bulge and the fixing column. The connecting mode saves common fixing screws, directly fixes the bracket 2 and the circuit board 1, and saves material cost and later-stage assembly cost. In this embodiment, the material of the bracket 2 is plastic.

The inside front end of support 2 is provided with the mounting groove, installs lens 6 in the mounting groove, and inside lens 6 was installed the mounting groove again along vertical installation. The front end of the bracket 2 is provided with an opening, the position of the opening is opposite to that of the lens 6, and the opening and the axis of the lens 6 are positioned on the same straight line.

The lamp pearl 3 is installed to the inside rear end of support 2, and the axis of lamp pearl 3 and anterior lens 6 is located the collinear. The lamp bead 3 is clamped by the fixing block 4 and the heat conducting fin 5.

Fixed block 4 is located lamp pearl 3 tops, fixed block 4 and support 2 fixed connection. In this embodiment, the fixing block 4 and the bracket 2 are fixed by glue. The fixing block 4 can ensure smooth assembly and also can ensure stable assembly of the lamp bead 3.

The conducting strip 5 is located the 3 below of lamp pearl, and the upper portion of conducting strip 5 contacts with two protruding portions of 3 sides of lamp pearl, derives the heat on the lamp pearl 3, avoids lamp pearl 3 to use the in-process for a long time, because of the high temperature damage. The lower part of the heat conducting sheet 5 is fixedly connected with the circuit board 1, and the heat conducted from the lamp beads 3 is transferred to the circuit board 1.

The upper portion of the support 2 is provided with a heat dissipation hole 7 and an adjusting hole 8, the heat dissipation hole 7 is used for dissipating heat of the internal structure of the support 2, and the adjusting hole 8 is used for adjusting the position of the lens 6.

According to the laser module, the copper pipe wall and the plastic wall are omitted, the thickness of the whole module is reduced, the spring and the copper pipe are also omitted, and the manufacturing cost and the assembling cost are saved. When the lamp beads are fixed, the combination of the fixing blocks and the heat conducting fins is adopted, so that the lamp beads can be fixed and can also be radiated, and further, the service life of equipment can be prolonged.

Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
