[0029] The following describes the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the utility model discloses a lighting module, including a circuit board 10, a lens assembly 20 and a heat sink assembly 30.

[0031] Among them, a light source is arranged on the circuit board 10, and the specific type of the light source is not limited here. A matrix light source can be used, and the matrix light source can improve the lighting effect. The lens assembly 20 is arranged in the light emitting direction of the light source, and the light emitted by the light source is emitted after the lens assembly 20 for lighting. The heat sink assembly 30 is arranged on the side of the circuit board 10 away from the lens assembly 20, and is used for heat dissipation of the circuit board 10. Specifically, the heat sink assembly 30 can be connected to the circuit board 10 by screws. One of the lens assembly 20 and the heat sink assembly 30 is provided with a sliding member 40, and the other is provided with a slide groove 50, and the slide groove 50 extends along the light emitting direction of the light source. The sliding member 40 and the slide groove 50 are slidably matched so that the lens assembly 20 can move along the light emitting direction to adjust the distance between the lens assembly 20 and the light source, so that a clear image can be obtained, high-pixel lighting can be achieved, and the resolution is improved to meet the lighting requirements. The lens assembly 20 includes a lens, and the lens can be made into any shape to meet the focusing requirements of various types of lenses.

[0032] like Figure 3As shown, in a specific embodiment of the present utility model, the sliding member 40 is arranged on the heat sink assembly 30, the slide groove 50 is arranged on the lens assembly 20, and a through hole for the sliding member 40 to pass through is opened on the circuit board 10. Specifically, the number of the slide grooves 50 is set to two, and the two slide grooves 50 are respectively arranged on the side of the lens assembly 20, and the sliding member 40 corresponds to the slide grooves 50 one by one.

[0033] In a specific embodiment, the sliding member 40 is a slider, and the slide groove 50 is a groove-shaped structure that slides with the slider. In a specific embodiment, the slider fits the side wall of the slide groove 50, and the slide groove 50 is away from the side wall of the lens assembly 20. A waist-shaped hole extending along the axial direction of the lens assembly 20 is provided on the slider, and a threaded hole is provided on the slide groove 50. After focusing is completed, the lens assembly 20 can be locked by passing a fastener through the waist-shaped hole and threadedly cooperating with the threaded hole.

[0034] In another specific embodiment, Figure 4-Figure 6 As shown, the slide groove 50 is a cylindrical structure, the sliding member 40 is a slide rod, the light source and the heat sink assembly 30 are fixed, and the slide groove 50 moves along the slide rod, so that the lens assembly 20 moves along the light emitting direction. The slide rod plays a guiding role when moving. Specifically, the radius of the slide rod is the same as the inner diameter of the slide groove 50, so that the circumference of the slide rod fits with the slide groove 50, as shown in FIG. Figure 4-Figure 6 As shown, during the focusing process and locking, the slide bar and the slide groove are in close contact. In order to ensure that the sliding member 40 and the slide groove 50 fit better, the cross section of the slide groove 50 perpendicular to the axis direction of the lens assembly 20 is greater than or equal to a semicircle.

[0035] After the focusing is completed, in order to lock the lens assembly 20, a fastener 60 is also included. Specifically, the sliding member 40 is provided with a waist-shaped hole extending along the light-emitting direction (i.e., extending along the axis direction of the lens assembly 20), and the slide groove 50 is provided with a threaded hole. The fastener 60 passes through the waist-shaped hole and is threadedly engaged with the threaded hole. The setting of the waist-shaped hole makes the distance between the lens assembly 20 and the light source adjustable.

[0036] In another specific embodiment, a waist-shaped hole extending along the axial direction of the lens assembly 20 is opened on the side wall of the slide groove 50, and threaded holes are opened on the sliding member 40 at equal intervals. The fastener passes through the waist-shaped hole and is threadedly engaged with the threaded hole to achieve distance adjustment between the lens assembly 20 and the light source.

[0037] When the focus needs to be adjusted, the fastener 60 is removed, and the sliding member 40 is slid along the slide groove 50 until the projected image is clear, and then the fastener is passed through the waist-shaped hole and threadedly engaged with the threaded hole to fix and lock the sliding member 40 and the slide groove 50, so that the position of the lens assembly 20 is fixed. The distance can be adjusted by setting the waist-shaped hole, which has a simple structure, convenient operation, and flexible adjustment.

[0038] In order to ensure the sealing of the lens assembly 20 , the lighting module disclosed in the embodiment of the utility model is provided with a sealing ring 70 between the lens assembly 20 and the circuit board 10 . Specifically, the sealing ring 70 is made of silicone.

[0039] The lighting module disclosed in the embodiment of the utility model can have a lens in a circular shape, a square shape or other shapes. The lens assembly 20 and the heat sink assembly 30 are slidably matched to meet the focusing requirements of various lenses and have a wider range of applications.
