Abstract

A light emitting diode (LED) cup light includes a base, a substrate, a LED light source and a fixing structure. The base includes a frame and a carrying member. The frame is surroundingly coupled to a periphery of the carrying member. The carrying member has a through hole. The substrate is disposed on the carrying member of the base. The LED light source is disposed on the substrate. The fixing structure presses on substrate and is engaged with a bottom surface of the carrying member of the base through the through hole.

Claims

1. A light emitting diode (LED) cup light, comprising:

a base comprising a frame and a carrying member, wherein the frame is surroundingly coupled to a periphery of the carrying member, and the carrying member has a through hole;

a substrate disposed on the carrying member of the base, the substrate comprising a first plate member and a second plate member disposed on the first plate member;

a LED light source disposed on the first plate member, wherein the second plate member surrounds a periphery of the LED light source; and

a fixing structure, which presses on the substrate and is engaged with a bottom surface of the carrying member of the base through the through hole.

2. The LED cup light according to claim 1, wherein the fixing structure comprises:

a pressing plate pressing on the substrate; and

a hook, which is coupled to the pressing plate, extends through the through hole from the pressing plate, and is engaged with the bottom surface of the carrying member.

3. The LED cup light according to claim 2, wherein:

the first plate member disposed on the carrying member of the base, and the pressing plate presses on the first plate member and surrounds a periphery of the second plate member.

4. The LED cup light according to claim 3, wherein an outer sidewall of the second plate member has a salient, an inner sidewall of the pressing plate has a notch, and the salient is accommodated within the notch.

5. The LED cup light according to claim 3, wherein a bottom surface of the pressing plate has a recess, and the substrate comprises:

an electrical pad disposed on the first plate member at a position corresponding to a position of the recess; and

a wire having one end, which is connected to the electrical pad and disposed in the recess.

6. The LED cup light according to claim 2, wherein the frame has an accommodating slot, which communicates with the through hole and accommodates the hook.

7. The LED cup light according to claim 2, wherein the fixing structure comprises two hooks.

8. The LED cup light according to claim 7, wherein hooking bodies of the two hooks face opposite directions.

9. The LED cup light according to claim 1, wherein the base is made of a metallic, plastic or composite material.

10. The LED cup light according to claim 1, wherein the fixing structure is made of a metallic, plastic or composite material.

11. The LED cup light according to claim 1, further comprising:

a thermoconductive insulating layer disposed between the substrate and the carrying member of the base.
