Abstract

A lighting apparatus includes a light source, a driver module and a surface rim. The light source includes multiple LED modules and a power electrode. The driver module includes a driver box and a first driver circuit. The first driver circuit is stored in the driver box. The first driver circuit is electrically connected to the power electrode of the light source for providing a driving current to the LED modules. The surface rim has a central portion and a peripheral portion. The light source is disposed to the central portion. The driver box is concealed at least partially by the peripheral portion.

First claim

The invention claimed is:

1. A lighting apparatus, comprising:
a light source comprising a plurality of LED modules and a power electrode;
a driver module comprising a driver box and a first driver circuit, the first driver circuit being stored in the driver box, the first driver circuit being electrically connected to the power electrode of the light source for providing a driving current to the LED modules;
a back plate; and
a surface rim having a central portion and a peripheral portion, the light source being disposed to the central portion and emitting a light to a central opening of the central portion, the driver box being concealed at least partially by the peripheral portion, the back plate being connected to the surface rim, the driver box being placed between the peripheral portion and the back plate, the peripheral portion having a surrounding side wall, the surrounding side wall having a container hole, the driver box having a lateral wall fitting the container hole, the surrounding side wall and the lateral wall together surrounding the central portion and the light source.

2. The lighting apparatus of claim 1 , wherein the driver box is disposed on a driver base for connecting to an external power source.

3. The lighting apparatus of claim 2 , wherein the peripheral portion has a container space, the driver box is kept in a portion of the container space.

4. The lighting apparatus of claim 3 , wherein the driver box has a sector shape.

5. The lighting apparatus of claim 3 , wherein the lateral wall of the driver box aligns with the surrounding wall of the peripheral portion of the surface rim so that the lateral wall appears as a part of the surrounding wall.

6. The lighting apparatus of claim 1 , wherein there are multiple types of the first driver circuit placed in the same shape of the driver box to be replaced to correspond to different types of the light source.

7. The lighting apparatus of claim 1 , wherein the electrode is plugging to a connector for receiving the driving current from the first driver circuit.

8. The lighting apparatus of claim 1 , wherein an augmented device is placed outside the lateral wall of the driver box, exposed toward the central opening.

9. The lighting apparatus of claim 8 , wherein the augmented device is an antenna used by the first driver circuit.

10. The lighting apparatus of claim 8 , wherein the augmented device is a sensor for collecting an environment status.

11. The lighting apparatus of claim 1 , wherein the peripheral portion of the surface rim provides a second container for storing an extended box.

12. The lighting apparatus of claim 11 , wherein the extended box contains a second driver circuit working together with the first driver circuit.

13. The lighting apparatus of claim 11 , wherein the extended box contains a function module for adding a function of the lighting apparatus.

14. The lighting apparatus of claim 13 , wherein the extended box contains a wireless hub circuit providing a wireless hotspot service.

15. The lighting apparatus of claim 13 , wherein the extended box contains a speaker for playing audio information.

16. The lighting apparatus of claim 11 , wherein the extended box is detachable from the peripheral portion of the surface rim.

17. The lighting apparatus of claim 11 , wherein the extended box provides an extended light source emitting light in addition to the light source.

18. The lighting apparatus of claim 1 , wherein the driver box is inserted into a container via the central opening and the container hole.

19. The lighting apparatus of claim 18 , wherein the driver box has a plugging structure to fix to the peripheral portion of the surface rim by plugging.

20. The lighting apparatus of claim 19 , wherein when the driver box is plugged into the container, the first circuit is electrically connected to an external power source and the light source when the driver box is plugged to the plugging structure.
