[0024] A lens light-emitting mechanism includes a housing 100; a light-emitting component 300 is provided inside the housing 100; the housing 100 is generally a thin-shell structure with a relatively large accommodation space inside. The housing 100 is vertically penetrated, and a light-transmitting plate 140 is installed at the opening at the top to protect the lens component 200 located inside the housing 100 from dust and water; the opening at the bottom of the housing 100 is used to install a heat dissipation component 500, which can achieve the sealing of the bottom of the housing 100; the heat dissipation component 500 includes a radiator 510; a heat dissipation fan 520 is provided at the bottom of the radiator 510; a protective cover 530 fixedly connected to the radiator 510 is provided at the bottom of the heat dissipation fan 520; the radiator 510 is generally the common radiator 510 structure in the art; a heat dissipation plane 511 is formed at the top of the radiator 510, and heat dissipation fins are arranged at intervals at the bottom of the heat dissipation plane 511; in one embodiment, a receiving cavity 512 is recessed in the heat dissipation plane 511; the receiving cavity 512 can be used to accommodate part of the lead screw motor 410, so as to reduce the occupation of the internal space of the housing 100 by the lead screw motor 410, and the lens component 200 can have more movable space; it can also be understood that when ensuring that the lens component 200 has sufficient movable space, the housing 100 can be set to a smaller size, so as to improve the effective utilization of the internal space of the housing 100;

[0025] The light-emitting component 300 is installed on the heat dissipation component 500; a plurality of lifting components 400 are fixedly connected to the light-emitting component 300; the movable end of the lifting component 400 is fixedly connected to the lens component 200 to realize the position adjustment of the lens component 200; in one embodiment, four lifting components 400 are provided; the lifting component 400 includes a lead screw motor 410 fixedly connected to the light-emitting component 300; one end of the lead screw 420 of the lead screw motor 410 is fixedly connected to the lens component 200 to drive the movement of the lens component 200; the lead screw motor 410 drives the lead screw 420 to move in a straight line direction; the movable end is one end of the lead screw 420, and usually the movable end is the top of the lead screw 420, which is arranged close to the lens component 200;

[0026] The heat dissipation component 500 is provided at the bottom of the light-emitting component 300; the light-emitting component 300 includes a circuit board 310; a plurality of light-emitting units 320 are uniformly provided on the circuit board 310; the light-emitting units 320 protrude from the circuit board 310; light is emitted from the top of the light-emitting units 320; the circuit board 310 is closely attached to the heat dissipation plane 511. The circuit board 310 generally refers to a light-emitting circuit board 310, that is, a circuit board 310 on which light-emitting units 320 are installed. Its close attachment to the heat dissipation plane 511 can achieve a better heat dissipation effect and ensure the normal operation of the light-emitting units 320;

[0027] The lens assembly 200 includes a mounting bracket 210, on which a plurality of light-shielding grooves 211 extending along the moving direction of the lens assembly 200 are evenly distributed; a lens 220 is provided at the top of the light-shielding groove 211; the lens 220 is fixedly connected to the mounting bracket 210 through a pressing plate 230; the bottom of the light-shielding groove 211 is disposed opposite to the light-emitting unit 320 in the light-emitting assembly 300; the depth of the light-shielding groove 211 is greater than the thickness of the lens 220, so that the light-shielding groove 211 has a certain depth to better shield the light-emitting unit 320 and reduce the light mixing between adjacent light-emitting units 320; the light-shielding groove 211 is usually integrally formed; a pressing edge portion is formed at the edge of the lens 220, and the pressing edge portion is abutted above through the pressing plate 230, and the pressing plate 230 is fixedly connected to the mounting bracket 210 to fix the lens 220;

[0028] In an embodiment of the present invention, a limiting portion 110 is formed inside the housing 100; the housing 100 is usually a thin-shell structure, and the limiting portion 110 is preferably a limiting portion 110 bent and protruding into the housing 100; an inner concave portion 212 opposite to the limiting portion 110 is provided on the mounting bracket 210; the inner concave portion 212 cooperates with the limiting portion 110, and usually the inner concave portion 212 is used to cooperate with the limiting portion 110 for avoiding position and saving space. When the limiting of the lens assembly 200 fails, the cooperation between the inner concave portion 212 and the limiting portion 110 can also ensure that the lens assembly 200 will not collide with the light-emitting assembly 300; as Figure 2 shown, the inner concave portion 212 is formed by hollowing out half of the light-shielding groove 211 area at the edge of the mounting bracket 210. Therefore, while ensuring the number of light-emitting units 320 remains unchanged, the occupation of the internal space is reduced; the limiting portion 110 is provided on both sides in the length direction of the housing 100 and is located in the middle of the housing 100, so that convex portions 120 and concave portions 130 are respectively formed on both sides of the housing 100 at the limiting portion 110; the light-emitting assembly 300 is disposed in the internal cavity where the concave portion 130 is located; usually, when ensuring the same number of light-emitting units 320, the housing 100 needs to be made according to the size of the convex portion 120, that is, each light-emitting unit 320 needs to correspond to a light-shielding groove 211, and the size of the complete light-shielding groove 211 is equivalent to the size between the convex portions 120 and cannot be further reduced; while in the present invention, the inner concave portion 212 is formed by hollowing out the light-shielding groove 211 at the edge, which not only ensures that each light-emitting unit 320 can correspond to a light-shielding groove 211 to ensure the independence of light output, but also reduces the volume, that is, the lower part of the housing 100 can be produced according to the size between the concave portions 130, reducing the cost; the limiting portion 110 formed by the concave portion 130 can also be in limiting cooperation with the inner concave portion 212, and when the limiting of the lens assembly 200 fails, mechanical structure is used for limiting, and the reliability is stronger.

[0029] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present utility model.
