In particular, the heat sink 2 can change the gear position through a gear adjustment component, so that the heat sink 2 can adjust its height up and down along the lifting bracket to change the irradiation position of the light source chip 21.

[0033] like Figure 6-7As shown, preferably, the panel assembly is detachably connected to the lamp holder 1, and the panel assembly includes a reflective panel 12 and a polarizing panel 13, and a plurality of snap buckles 14 are provided on the reflective panel 12 and the polarizing panel 13; a second annular groove 15 is provided on the inner side wall of the lamp holder 1, and a plurality of snap buckles 14 can be snap-connected to the second annular groove 15 so as to install the reflective panel 12 or the polarizing panel 13 on the lamp holder 1. In the conventional lighting mode of the present invention, the reflective panel 12 is used to enhance the illumination effect of the light source chip 12, and when used as a wall washer or an atmosphere lamp, the snap buckles 14 can be used to realize quick disassembly and assembly to replace the polarizing panel 13.

[0034] In particular, the panel assembly is usually square or circular, and the shapes of the reflective panel 12 and the polarizing panel 13 are adapted to the inner shape of the lamp holder 1 .

[0035] Furthermore, if Figure 5 As shown, the optical assembly is detachably connected to the heat sink 2, and the optical assembly includes an adapter pressure ring 33 and a lens 34. A screw ring 25 is provided at the lower end of the heat sink 2, and the light source chip 21 is arranged in the screw ring 25 and connected to the heat sink 2 through a fixing frame 26; the adapter pressure ring 33 is screwed together with the screw ring 25, so that the lens 34 is paired and arranged on the light source chip 21.

The swivel bracket 3 is rotatably matched with the first annular groove 11 by the marble 32, so that the heat sink 2 can be horizontally rotated on the lamp holder 1 through the swivel bracket 3. It can be understood that an elastic pad is arranged in the ball hole 31, and the outer diameter of the swivel bracket 3 is smaller than the inner diameter of the upper port of the lamp holder 1 so that there is a clearance fit between the two, and the marble 32 protrudes from the outer edge surface of the swivel bracket 3 so that it can be snapped on the first annular groove 11. When the swivel bracket 3 is installed in the lamp holder 1, the marble 32 is squeezed to compress the elastic pad and shrink it into the ball hole 31. When the marble 32 is matched with the first annular groove 11, the elastic pad touches the marble 32 to protrude from the swivel bracket 3, so that the swivel bracket 3 can be rotatably arranged in the upper port of the lamp holder 1. The connection strength between the marble 32 and the first annular groove 11 is sufficient to support the overall weight of the heat sink 2. Of course, when disassembling, a large force is applied to the heat sink 2 to allow the marble 32 to slide out of the first annular groove 11.

[0038] like Figure 3 , 8 -11, the lifting bracket includes two connecting pieces 4, and the lower end of the connecting piece 4 is rotatably connected to the rotating bracket 3 through an axial screw 41; the radiator 2 is arranged between the two connecting pieces 4, and the radiator 2 is slidably connected to the connecting piece 4, and the gear adjustment component is arranged on the radiator 2, and the gear adjustment component is respectively connected with the two connecting pieces 4.

The spring 51 contacts the self-locking bracket 5 to make the gear bolt 52 buckle on the slot 44. When the gear bolt 52 on the self-locking bracket 5 is buckled on the slot 44, the radiator 2 is locked in a vertical position through the self-locking bracket 5 and the connecting piece 4, and the locking is limited by the spring 51. The spring 51 drives the gear bolt 52 on the self-locking bracket 5 to lock on the slot 44. Furthermore, when the self-locking bracket 5 overcomes the force of the spring 51, the gear bolt 52 is detached from one of the slots 44, so that the radiator 2 can move up and down along the connecting piece 4 to adjust the gear position, and the gear bolt 52 can slide in the gear slot 45 to select the corresponding slot 44. The self-locking bracket 5 is released, and the gear bolt 52 on it is buckled in another slot 44 to lock the height of the radiator 2.

[0041] The connecting piece 4 of the present invention is provided with two slots 44 , that is, the radiator 2 has two adjustment modes, high gear and low gear. When there are two slots 44 , they form a “C”-shaped structure with the gear slot 45 .

[0042] Alternatively, three slots 44 are provided on the connecting plate 4, that is, the radiator 2 has three adjustment modes: high-range, medium-range and low-range. When there are three slots 44, they form an "E"-shaped structure with the gear slot 45. Of course, the number of slots 44 can be more.

[0043] The action cavity 22 passes through the upper end surface of the radiator 2. A cover plate 23 is provided on the radiator 2. The cover plate 23 is covered on the action cavity 22 so that the self-locking bracket 5 can slide horizontally in the action cavity 22. A lock hole 24 is provided on the side wall of the radiator 2.
