DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-6 As shown, a high-brightness SMD light source lamp with adjustable light output angle includes a lamp holder 10 and a strip frame 20. The lamp holder 10 includes mounting seats 12 arranged on both sides of the strip frame 20 and a connecting plate 13 connecting the two mounting seats 12. The mounting seats 12 are provided with assembly holes. The SMD light source lamp fixes the lamp holder 10 at a desired position by fasteners.

[0028] The strip frame 20 is rotatably mounted on the lamp holder 10 via a rotating shaft 30, and the connecting plate 13 is arranged at the upper end of the rotating shaft 30. Specifically, a support block 21 which rotates synchronously with the rotating shaft 30 is provided at the upper end of the strip frame 20, and a reduction motor 60 connected to the rotating shaft 30 is installed in the block on one side of the lamp holder 10. The reduction motor 60 is controlled by a control switch to drive the strip frame 20 and the lighting assembly 40 arranged in the strip frame 20 to rotate relative to the lamp holder 10, thereby adjusting the light emission direction of the lighting assembly 40.

[0029] The strip frame 20 is divided into an upper chamber and a lower chamber by a partition 24. A lighting assembly 40 is arranged in the lower chamber. The lighting assembly 40 includes a PCB board 41, a plurality of SMD light sources 42 mounted on the PCB board 41, and a fin heat sink 43 arranged on the inner side of the PCB board 41. The partition 24 is provided with a channel for the fin heat sink 43 to extend into the upper chamber. A cooling fan 50 is arranged in the upper chamber. The strip frame 20 is provided with an air inlet and an air outlet. By setting a heat dissipation structure, a large amount of heat generated by the SMD can be quickly taken away, thereby effectively improving the service life of the high-brightness SMD light source 42 lamp.

[0030] The cooling fans 50 are provided in two groups, and the two cooling fans 50 are respectively arranged on both sides of the fin radiator 43. The upper chamber is provided with an air guide cover 22, and the air guide cover 22 includes a left side portion, a middle portion and a right side portion, wherein the left air guide cover 22 is inclined from top to bottom, and the middle air guide cover 22 is used to transfer the cooling air to the right air guide cover 22, and the right air guide cover 22 is inclined from bottom to top. The purpose of this setting is to guide the cooling air to the fin radiator 43, thereby effectively dissipating the heat of the fin radiator 43.

[0031] The fin length direction of the fin heat sink 43 is on the same side as the length direction of the strip frame 20. The purpose of this arrangement is to prevent the fins of the fin heat sink 43 from blocking the cooling air from blowing toward the air outlet. Furthermore, the cooling fan 50 is an axial flow fan.

[0032] An adjustment positioning mechanism 70 is provided between the support block 21 and the block body, and the rotating shaft 30 is positioned at the position after rotation by the adjustment positioning mechanism 70. That is to say, the purpose of setting the adjustment positioning mechanism 70 is to stably position the lighting lamp group after the adjustment position to prevent it from rotating again and affecting its light output angle.

[0033] The adjustment and positioning mechanism 70 includes a fixing block 71 fixedly connected to the lamp holder 10 and a fixing ring 72 fixedly installed on the end surface of the support block 21. The outer periphery of the fixing ring 72 is provided with a ratchet portion 721 that can be elastically deformed. The fixing block 71 is provided with an inner gear ring 711 that accommodates the fixing ring 72. The inner gear ring 711 is meshed with the ratchet portion 721. A through hole is provided in the center of the fixing ring 72 for the rotation shaft 30 to pass through. The ratchet portion 721 includes an elastic arm 7211 and a tooth portion 7212 formed on the outer periphery of the elastic arm 7211. The elastic arm 7211 is formed on the fixing A through groove 7213 is provided on the outer periphery of the ring 72 and between the ring 72 and the fixed ring 72, so that the ratchet portion 721 can be elastically deformed relative to the fixed ring 72. When the reduction motor 60 drives the rotating shaft 30 and the support block 21 to rotate, the fixed ring 72 will be equivalent to the rotation of the fixed block 71. Since the ratchet portion 721 has a certain elastic deformation, it can be ensured that the ratchet portion 721 can be equivalent to the rotation of the inner ring gear 711. When the reduction motor 60 stops running, the ratchet portion 721 will be locked and positioned with the inner ring gear 711, thereby effectively positioning the lighting assembly 40 in the adjusted position.

[0034] The fixing ring 72 is provided with a plurality of circumferentially arranged positioning pins 722 on one side adjacent to the support block 21, and the support block 21 is provided with positioning grooves for positioning and cooperating with the positioning pins 722. The other end of the fixing ring 72 relative to the positioning pins 722 contacts the inner end surface of the fixing block 71. Through this arrangement, the fixing ring 72 and the support block 21 can be rotated. At the same time, compared with the screw fixed connection, its assembly is more convenient and quick, and its processing is also more convenient.

[0035] The lamp holder 10 is provided with an arc-shaped guide groove 11 on one side corresponding to the strip frame 20, and the arc-shaped guide groove 11 is arranged with the rotating shaft 30 as the axis. The side end of the strip frame 20 is provided with a guide column 23, through which a guiding role can be played, so that the operation of the strip frame 20 is more stable and smooth. At the same time, the guide column 23 can play a certain supporting role and share the pressure on the rotating shaft 30.

[0036] Furthermore, an aspherical cylindrical lens 80 is provided at the bottom of the strip frame 20 corresponding to the lighting assembly 40 , and the aspherical cylindrical lens 80 is arranged along the length direction of the strip frame 20 .

[0037] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
