[0007] Furthermore, the first light source is a COB light source, and the second light source is an LED light source.

[0008] Furthermore, the COB light source is fixed to the inner top surface of the first groove through a COB bracket. The bottom edge of the first heat sink is also provided with a ring-shaped aluminum substrate, which extends around the circumference of the first groove, and the LED light source is arranged on the aluminum substrate.

[0009] Furthermore, the bottom wall of the reflector is plate-shaped, and the first reflector and the second reflector protrude upward from the bottom wall of the reflector.

[0010] Furthermore, the first reflector and the second reflector are in the shape of a truncated cone with diameters gradually decreasing from bottom to top, and the first reflector and the second reflector are in a hollow shape penetrating from top to bottom.

[0011] Furthermore, the bottom wall of the lens is plate-shaped, and the first lens and the second lens protrude upward from the bottom wall of the lens; the lens angle of the first lens is 24°±3°, and the lens angle of the second lens is 50°±3°.

[0012] Furthermore, the first lens and the second lens are frustum-shaped with diameters gradually decreasing from bottom to top, the top of the first lens is provided with a second groove that cooperates with the first light source, the bottom of the first lens is provided with a third groove, and the top of the second reflector is provided with a fourth groove that cooperates with the second light source.

[0013] Furthermore, a second heat sink is sleeved on the outside of the first heat sink, the top wall of the second heat sink is connected and fixed to the top wall of the first heat sink, and the bottom edge of the second heat sink extends downward to the edge of the lens.

[0014] Furthermore, a metal lampshade is provided on the outside of the second radiator, the top wall of the metal lampshade is connected and fixed to the top wall of the second radiator, and the bottom edge of the metal lampshade extends outward in an umbrella shape; a connecting pipe is provided in the middle of the top of the second radiator, which passes upward through the metal lampshade, and the connecting pipe is connected to the tail rod.

[0015] In summary, the technical solution of the present invention has the following beneficial effects: The structural design of the present invention is reasonable. (1) The first radiator is provided with a first light source in the middle of the bottom of the first radiator, and a plurality of second light sources are provided at the bottom edge of the first radiator; a reflector is provided below the first radiator, a first reflector is provided in the middle of the reflector, and a plurality of second reflectors are provided at the edge of the reflector.

(3) The lens angle of the first lens is smaller than the lens angle of the second lens; thus, two groups of light sources can be used to correspond to two lens angles, such as a 24° middle lens and a 50° angle for the six small lenses on the periphery (of course, other corresponding angles are also possible). A three-speed power switch can be used to switch and select the first and second light sources, thereby switching and selecting the lens angles, and further adjusting the light spot size (i.e., focusing function). From the above analysis, it can be seen that when used in dining pendant light scenes: Scene 1: When there are few people, a small angle can be selected, the lighting range is small, and precise lighting can be achieved; Scene 2: When there are many people, a large and small angle can be selected first, the lighting range is large, and floodlighting can be achieved; therefore, the utility model can replace manual adjustment of the zoom to achieve the light spot size, saving the difficulty of installation and adjustment, and the lighting can be selected in multiple scenes, with convenient operation and high cost performance.

[0028] Specifically, a first groove 101 that is recessed upward is provided in the middle of the bottom of the first heat sink 1. A first light source 2 is disposed on the inner top surface of the first groove 101. A plurality of second light sources 3 are distributed sequentially around the circumference of the first groove 101, with the first light source 2 being higher than the second light sources 3. Function: By having the first light source 2 be higher than the second light source 3, the first light source cooperates with the first lens, and the second light source cooperates with the second lens, thereby better adjusting the light spot size (i.e., focusing function). Preferably, the number of first light sources is one, and the number of second light sources is six, but other numbers are also possible.

[0029] Specifically, the first light source 2 is a COB light source, and the second light source 3 is an LED light source. Purpose: Choosing this type of light source provides sufficient brightness and facilitates integration with lenses and reflectors.

[0032] Specifically, the first and second reflectors 401, 402 are truncated cones with diameters gradually decreasing from bottom to top. They are hollow and extend vertically through the first and second reflectors 401, 402. Function: The first and second light sources 2, 3 extend into the hollow spaces of the first and second reflectors 401, 402, while the truncated cones 401, 402 provide a better reflective effect.

[0033] Specifically, the bottom wall of lens 5 is plate-shaped, with first lens 501 and second lens 502 protruding upward from the bottom wall. The lens angle of first lens 501 is 24°±3°, and the lens angle of second lens 502 is 50°±3°. Function: The upward protrusion of the lens provides a better refraction effect for first light source 2 and second light source 3. This angle arrangement is suitable for the combination of first lens 501 and second lens 502, making it convenient for daily use.

[0034] Specifically, the first lens 501 and the second lens 502 are frustoconical in shape, with diameters gradually decreasing from bottom to top.

[0035] Specifically, a second heat sink 8 is sheathed around the exterior of the first heat sink 1. The top wall of the second heat sink 8 is fixedly connected to the top wall of the first heat sink 1, and the bottom edge of the second heat sink 8 extends downward to the edge of the lens 5. Function: The combination of the first heat sink 1 and the second heat sink 8 can enhance heat dissipation. Preferably, the first heat sink 1 and the second heat sink 8 are aluminum heat sinks.

[0036] Specifically, a metal lampshade 9 is sheathed around the exterior of the second radiator 8. The top wall of the metal lampshade 9 is fixedly connected to the top wall of the second radiator 8, and the bottom edge of the metal lampshade 9 extends outward in an umbrella shape.
