DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] A light-cutting lamp that can be rotated to adjust the irradiation angle, referring to Figure 1-3 , including a rail head 1, which is slidably inserted on the external powered rail, and a conductive magnet 101 is arranged on the top of the rail head 1. The conductive magnet 101 is magnetically attracted to the power connection plate of the external power supply in the external powered rail. Through the cooperation of the conductive magnet 101 and the power connection plate, the rail head 1 can be magnetically attracted and electrically connected to the external powered rail to provide a power source for the lighting component.

[0022] Among them, the powered track is a commonly used accessory for existing track lights, and the specific structure will not be described again.

[0023] Furthermore, it also includes a lighting assembly, which is arranged below the track head 1. The lighting assembly includes a heat sink 9, a light source assembly and a light cutting mechanism 5 arranged in front of the light source assembly. The light cutting mechanism 5 includes a mounting ring 56, a first cylinder 52 and a second cylinder 55 threadedly connected to the first cylinder 52, which are arranged in sequence. The first cylinder 52 and the second cylinder 55 respectively accommodate a first plano-convex mirror 57 and a second plano-convex mirror 54. By rotating the second cylinder 55 outward or inward, the distance between the plano-convex mirrors in the first cylinder 52 and the second cylinder 55 can be adjusted. According to the change in the spacing between the first plano-convex mirror 57 and the second plano-convex mirror 54, the range of light irradiation and the brightness of the light can be adjusted, so that the illuminated area or object can be well displayed under perfect lighting.

[0024] Furthermore, it also includes an angle adjustment component, which is arranged between the rail head 1 and the radiator 9. The angle adjustment component includes an L-shaped frame 3, an upper segment 2 and a lower segment 8. One end of the upper segment 2 and the lower segment 8 are respectively fixed to the upper horizontal part and the lower vertical part of the L-shaped frame 3, and the other ends of the upper segment 2 and the lower segment 8 are respectively rotatably connected to the rail head 1 and the radiator 9. By designing the upper segment 2 and the lower segment 8 movably connected to the lighting component and the rail head 1 on the L-shaped frame 3, the overall structure is simple, and the horizontal and upper and lower angles of the lighting component can be adjusted at will, so that the light projection can be concentrated on a certain object (area).

[0025] Furthermore, gaskets 6 are provided at the connections between the upper and lower segments 2, 8 and the rail head 1 and the radiator 9. The gaskets 6 can increase the damping of the connections between the upper and lower segments 2, 8 and the rail head 1 and the radiator 9, thereby ensuring the stability of the connections between the upper and lower segments 2, 8 and the rail head 1 and the radiator 9.

[0026] Furthermore, a mounting ring 56 is mounted on the bottom of the radiator 9, and a plurality of strip holes are provided in the circumferential direction of the mounting ring 56, in which a shading plate 53 is inserted, which can swing in the strip holes under force and can extend into the interior of the mounting ring 56, and a light emitting area is formed between the plurality of shading plates 53. External force acts on the shading plates 53 to move the shading plates 53 in the strip holes, thereby adjusting the size and shape of the light emitting area formed between the shading plates 53. Anti-slip strips for positioning the shading plates 53 are provided at the upper and lower ends of the strip holes, and a paddle 51 extends from the outer end of the shading plate 53 to the outside of the strip holes, and the outer end of the paddle 51 is covered with a silicone sleeve, and the shading plate 53 can be moved by the paddle 51, and the size and shape of the emitted light spot can be adjusted according to the actual needs of the user. When the emitted light spot is irradiated on the desired area (object), the display effect will be clearer and more vivid.

[0027] Furthermore, the light source assembly includes a COB light source 10 and a light source bracket 4. The COB light source 10 is fixed inside the radiator 9 through the light source bracket 4. The COB light source 10 emits light evenly, which can directly overcome the shortcoming of high-power and dazzling LEDs on the market. Secondly, the precise packaging process of the COB light source 10 allows the chip to be fully cooled to ensure the quality of the chip and extend its life.

[0028] Furthermore, the heat sink 9 accommodates a driving power supply (not shown in the figure) electrically connected to the conductive magnet 101. The upper end of the heat sink 9 is detachably mounted with a rear cover 7, and a plurality of ventilation holes are opened circumferentially on the rear cover 7. The driving power supply is electrically connected to the COB light source 10. The driving power supply is separately integrated in the lighting assembly, and each lamp body can be separately controlled by its own driving power supply (multiple lamp bodies can be installed on the track according to actual needs), thereby increasing the overall functionality. The ventilation holes on the rear cover 7 can also assist in heat dissipation needs.

[0029] Furthermore, the heat sink 9 is made of aluminum alloy as a whole, and a plurality of heat dissipation fins are arranged on the inner circumference of the heat sink 9. The heat generated by the COB light source 10 and the driving power supply can be discharged outward through the heat sink 9, thereby satisfying the normal operation of the lighting component.
