Lighting apparatus

1. A lighting apparatus, comprising:

a top cover having a top surface, a slope surface and an inner wall, wherein the slope surface and an inner wall form a cavity below the top surface, the inner wall has a light opening;

a light source for emitting a light with a first direction via the light opening of the top cover, wherein the light is guided by the slope surface to move with a second direction to escape from the top surface of the top cover, wherein the light source comprises a LED module and a driver for generating a driving current supplied to the LED module to emit the light;

a bottom cover to be plugged to fix to the top cover; and

a sensor coupled to the driver for detecting an external event to change a setting of the driver to control the LED module, wherein the sensor comprises a motion sensor to detect a movement of an object for the driver to determine whether to turn on or turn off the LED module.

2. The lighting apparatus of claim 1 , wherein the top cover and the bottom cover are fixed together with a buckle structure.

3. The lighting apparatus of claim 1 , wherein the light source has a diffusion lens for diffusing the light of the LED module before being emitting to the slope surface.

4. The lighting apparatus of claim 1 , wherein the bottom cover has a battery container for loading a battery, the driving current is supplied by the battery.

5. The lighting apparatus of claim 4 , wherein a bottom surface of the bottom cover has a battery opening for inserting the battery.

6. The lighting apparatus of claim 1 , wherein the inner wall has an installation side disposed with the light opening, the light opening faces to the slope surface of the top cover for reflecting light, the LED module is disposed behind the light opening of the inner wall.

7. The lighting apparatus of claim 6 , wherein the LED module is disposed on a first circuit board mounted on a second circuit board, the second circuit board is disposed on a platform of bottom cover for aligning the LED module to the light opening of the top cover.

8. The lighting apparatus of claim 6 , wherein a reflective layer is disposed on the slope surface.

9. The lighting apparatus of claim 8 , wherein the reflective layer is detachable attached to the slope surface to be manually replaced with another reflective layer.

10. The lighting apparatus of claim 8 , wherein the reflective layer has multiple wave structures.

11. The lighting apparatus of claim 6 , wherein a light guide plate is placed on the slope surface, the LED module emits the light into a lateral side of the lateral guide plate for the light to escape from a main surface of the light guide plate.

12. The lighting apparatus of claim 1 , wherein the LED module is connected to a rotatable structure so as to adjust the first direction of the LED module to the slope surface.

13. The lighting apparatus of claim 1 , wherein the bottom cover has an electrical plug to be plugged to an external electrical socket to receive a power supply to the driver.

14. The lighting apparatus of claim 1 , further comprising a manual switch disposed on a surface of the top cover, wherein the manual switch is operated to instruct the driver to change a setting to the LED module.

15. The lighting apparatus of claim 1 , wherein the sensor comprises a light sensor to detect an ambient light level for the driver to automatically determine whether to turn on or turn off the LED module according to the ambient light level.

16. The lighting apparatus of claim 1 , wherein the slope surface is attached with a touch input device coupled to the driver to control the LED module.

17. The lighting apparatus of claim 1 , wherein the slope surface is attached with touch input device coupled to the driver to wirelessly control another light device.

18. The lighting apparatus of claim 1 , wherein multiple function modules are detachably stacked to the top cover to add functions of the multiple function modules.
