Abstract

The lighting apparatus has a wire box, a driver module, a light source and a light housing. The wire box is made of a heat dissipation material. The wire box is for placing a portion of an external wire. The driver module electrically connects to an electrode of the portion of the external wire. The light housing has a top cover and a surrounding wall. The top cover and the surrounding wall form a container space. The top cover has an inner side and an exterior side. The light source is thermally and structurally connected to the inner side for emitting a light via a light opening of the container space. The wire box is connected to the top cover of the light housing. Heat of the light source is transmitted to the wire box for heat dissipation via the back cover.

First claim

The invention claimed is:

1. A lighting apparatus comprising:
a wire box made of a heat dissipation material for placing a portion of an external wire;
a driver module for electrically connecting to an electrode of the portion of the external wire;
a light source; and
a light housing having a top cover and a surrounding wall forming a container space, the top cover having an inner side and an exterior side, the light source being thermally and structurally connected to the inner side for emitting a light via a light opening of the container space, the wire box being connected to the top cover of the light housing, heat of the light source being transmitted to the wire box for heat dissipation via the back cover, wherein the wiring box has a connector for elastically connecting two side wings, the two side wings are levers defining an expandable diameter for inserting into an installation cavity and keeping the lighting apparatus to the installation cavity, wherein an antenna is disposed on the side wings, the antenna is electrically connected to a wireless circuit of the driver, wherein the wiring box has multiple installation slots for installing multiple slot modules, the driver is made as one slot module, wherein the driver has a main module selectively integrated with selected function modules, the function module is made as one slot module, wherein wiring box has a conductive path, when the driver is installed to the wiring box, the driver is plugged to the wiring box and uses the conductive path for electrically connecting to external wire and the light source.

2. The lighting apparatus of claim 1 , wherein the exterior side of the top cover of the light housing is connected to a bottom cover of the wiring box, the light source comprises a light source plate mounted with multiple LED chips, heat of the LED chips is transmitted to the light source plate, the top cover of the light housing and the bottom cover of the wiring box.

3. The lighting apparatus of claim 1 , wherein the two side wings are elastic levers with a central spring connected to the wiring box.

4. The lighting apparatus of claim 1 , wherein the wiring box has a U shape structure connected to the side wing with a spring.

5. The lighting apparatus of claim 1 , wherein the side wings are heat conducted to the wiring box.

6. The lighting apparatus of claim 1 , wherein the driver has a box housing and a driver circuit, the driver circuit is enclosed in the box housing, the box housing has a side attached to an inner wall of the wiring box.

7. The lighting apparatus of claim 6 , wherein the box housing is attached to a top side of the wiring box away from the light housing.

8. The lighting apparatus of claim 1 , wherein the wiring box is a metal box.

9. The lighting apparatus of claim 1 , wherein the wiring box has a fan and a gas exit for moving away heat in the wiring box.

10. The lighting apparatus of claim 9 , wherein the fan is selectively inserted to the wiring box, the driver provides a fan current to drive the fan.

11. The lighting apparatus of claim 1 , wherein the wiring box has a plugging interface for connecting the external wire.

12. The lighting apparatus of claim 1 , wherein the wiring box has multiple fins folded from a surface of the wiring box forming multiple corresponding openings.

13. The lighting apparatus of claim 1 , wherein a connection part between the lighting housing and the wiring box is filled with heat dissipation gel.
