[0039] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0040] Please refer to Figure 1-Figure 6A lamp comprises a radiator 1, a first light-emitting component 2 and a second light-emitting component 3; the radiator 1 has a main light-emitting cavity 11 and an annular light-emitting cavity 12; the first light-emitting component 2 is arranged in the main light-emitting cavity 11, the second light-emitting component 3 is installed in the annular light-emitting cavity 12, and the second light-emitting component 3 is arranged around the first light-emitting component 2; the second light-emitting component 3 comprises a reflector 31, a light guide 32 and an annular light-emitting component 33; the reflector 31 is connected to the radiator 1, the annular light-emitting component 33 is arranged around the annular light-emitting cavity 12 and is arranged opposite to the reflector 31, and the light guide 32 is embedded in the light-emitting end of the annular light-emitting cavity 12.

[0041] It is understandable that by setting the first light-emitting component 2 and the second light-emitting component 3, different areas of the lamp can be independently illuminated. According to the different requirements of the user for illumination, it is selected to let the first light-emitting component 2 or the second light-emitting component 3 emit light independently, or to let the first light-emitting component 2 and the second light-emitting component 3 emit light at the same time, that is, when the first light-emitting component 2 and the second light-emitting component 3 emit light at the same time, the brightness of the lamp is the greatest; when the first light-emitting component 2 emits light independently and the second light-emitting component 3 does not emit light, the brightness of the lamp is second; when the first light-emitting component 2 does not emit light and the second light-emitting component 3 emits light independently, the brightness of the lamp is the weakest. Since the reflector 31 is arranged between the main light-emitting cavity 11 and the annular light-emitting cavity 12, it plays a role in blocking the propagation of light, reduces light scattering and light energy loss, and ensures the illumination when the light propagates outward. Since the first light-emitting component 2 and the second light-emitting component 3 are respectively arranged in two independent cavities, the utility model meets the use requirements of different scenes.

[0042] In some embodiments, the first light-emitting assembly 2 includes a diffusion cover 21, a main light-emitting element 22 and a light-transmitting cover 23; the light-transmitting cover 23 is disposed outside the main light-emitting element 22; the diffusion cover 21 is disposed on the main light-emitting cavity 11 and is engaged with the reflector 31. The diffusion cover 21 is provided to diffuse the light and improve the softness and diffusion effect of the light. The light-transmitting cover 23 is provided to protect the main light-emitting element 22 and should be made of a transparent material. The main light-emitting element 22 is an LED light board.

[0043] In some embodiments, at least two clamping platforms 311 are provided on the side wall of the reflector 31 away from the main light emitting element 22; the clamping platform 311 is gradually away from the light emitting end of the reflector 31 along the circumference of the reflector 31. A clamping groove 313 is provided on the guiding inclined surface 312; a clamping block 211 capable of clamping with the clamping platform 311 is provided on the side of the diffuser 21 facing the main light emitting element 22. A limiting block 314 is provided at the highest point of the guiding inclined surface 312; and the clamping block 211 can be pressed against the limiting block 314 in the circumference of the reflector 31. The cooperation between the clamping platform 311 and the clamping block 211 enables the diffuser 21 and the reflector 31 to be disassembled and connected in a rotating manner. Specifically, the clamping block 211 is provided with a protrusion 212 that matches the clamping groove 313. During the relative rotation of the reflector 31 and the diffuser 21, the protrusion 212 will move relative to the guide slope 312 until the protrusion 212 is embedded in the clamping groove 313, and the clamping block 211 will also be pressed against the limit block 314. The setting of the protrusion 212 enables the reflector 31 to be locked with the diffuser 21, thereby improving stability. The setting of the limit block 314 is used to limit the clamping block 211 at the end of the travel of the guide slope 312, thereby improving the positioning accuracy of the protrusion 212 and the clamping groove 313.

[0044] In some embodiments, all the clamping platforms 311 are arranged at equal intervals. Optionally, two, three, four or more clamping platforms 311 and clamping blocks 211 are respectively arranged.

[0046] In some embodiments, in the axial direction of the heat sink 1, two symmetrically arranged springs 6 are arranged on one side of the heat sink 1 away from the first light-emitting assembly 2; the two springs 6 are arranged at both ends of the heat sink 1 in the radial direction. The arrangement of the springs 6 is used to enable the heat sink 1 to be connected to the Halo tube.

[0047] In some embodiments, a slide groove 13 for sliding connection with the bolt 4 is provided on the side of the heat sink 1 away from the first light-emitting component 2; at least two slide grooves 13 are provided, and all the slide grooves 13 are arranged along the radial direction of the heat sink 1. Preferably, multiple groups of slide grooves 13 can be provided, and each group is provided with two centrally symmetrical slide grooves 13, so that the slide groove 13 is connected to the corresponding bolt 4 in a rotational manner. Specifically, the slide groove 13 has a first through hole 131 and a second through hole 132 that are connected in sequence, wherein the aperture of the first through hole 131 is smaller than the aperture of the second through hole 132, and the bolt 4 is inserted through the second through hole 132 and can slide into the first through hole 131 for fixing, so that the heat sink 1 is connected to the octagonal box 5 through the bolt 4, enriching the connection method of the lamp so that the lamp can be assembled in different scenes.

[0048] In some embodiments, the heat sink 1 has a heat dissipation cavity 14, and the heat dissipation cavity 14 is arranged around the annular light-emitting cavity 12 to expand the heat dissipation area and improve the heat dissipation effect.
