Abstract

A lighting apparatus includes a driver, a bottom cover, a light source module, a lens module, a light passing cover and a base plate. The bottom cover has a first central opening a driver container for storing the driver. The light source module has multiple LED modules and a second central opening. The lens module has a third central opening and multiple diffusion lenses respectively placed above the multiple LED modules. The lens module is fixed to the bottom cover to make the light source module, the driver, the lens module and the bottom cover as a portable module. The first central opening, the second central opening and the third central opening together form a main central opening. The base plate may be fixed to an installation platform.

First claim

The invention claimed is:

a light passing cover; and
a base plate for fixing to an installation platform, wherein the the bottom cover is fixed to the base plate, the base plate has multiple connectors for detachably connecting the light passing cover, wherein a smart control module is electrically connected to the driver and is placed in the main central opening.

2. The lighting apparatus of claim 1 , further comprising a heat dissipation plate, wherein the heat dissipation plate is placed between the driver and the light source module, the heat dissipation plate has a fourth central opening, the fourth central opening corresponding to the main central opening.

3. The lighting apparatus of claim 1 , wherein the lens module is a transparent plastic plate, the multiple diffusion lenses are formed directly on the transparent plastic plate.

4. The lighting apparatus of claim 1 , wherein at least some of the LED modules have two types of LED chips.

5. The lighting apparatus of claim 1 , wherein the light source module has multiple light source sectors.

6. The lighting apparatus of claim 1 , wherein the driver has a first driver connector to attach to a second driver connector disposed on the bottom cover to fix driver to the bottom cover.

7. The lighting apparatus of claim 1 , wherein the multiple connectors comprises a buckle plate and two rotation buckle pins.

8. The lighting apparatus of claim 1 , wherein the bottom cover has an inner wall defining the first central opening, the base plate has at least a central protruding unit for aligning the inner wall of the bottom cover.

9. The lighting apparatus of claim 1 , wherein a battery is detachably disposed in a container space between the bottom cover and the light source module.

10. The lighting apparatus of claim 1 , wherein there are tilt angles for placing the LED modules respect to the light passing cover for directing lights of the LED modules evenly on the light passing cover.

11. The lighting apparatus of claim 1 , wherein the smart control module is detachable connected to a extending terminal disposed on an inner wall of the bottom cover.

12. The lighting apparatus of claim 3 , wherein the lens module has a buckle structure to fix to the bottom cover for concealing the driver and the light source module.

13. The lighting apparatus of claim 5 , wherein the multiple light sources have buckle units for connecting the multiple light source sectors.

14. The lighting apparatus of claim 6 , wherein the bottom cover has a conductive path for electrically connecting the driver to the light source module.

15. The lighting apparatus of claim 8 , wherein there are multiple central protruding units, each central protruding unit has an elastic hook for deforming when inserting the bottom cover to the base plate and for holding the bottom cover to the base plate with elastic force of the multiple central protruding units.
