Abstract

A wireless light board is disclosed herein. The present invention comprises a baseplate, a backlight module, a power module, a proximity sensor module, a control module, at least one bottom cover, and a top cover. The baseplate has a recess and a power source accommodation hole to respectively accommodate the backlight module and the power module. The control module is arranged on a circuit board and electrically connected with the backlight module and the proximity sensor module to turn on/off the backlight module. The bottom cover removably covers the power source accommodation hole. The top cover covers at least the backlight module and the power module and has a first light-permeable region above the backlight module. Thereby, the wireless light board is slim, waterproof, power-saving, easy to install, and convenient for battery replacement.

Claims

1. A wireless light board comprising

a baseplate having an upper surface and a lower surface, wherein said upper surface has at least one recess, and wherein at least one side of said recess has a power source accommodation hole, and wherein a positioning portion is defined on at least one side of said baseplate;

a backlight module accommodated by said recess and having at least one circuit board;

a power module including at least one battery and at least one conductive strip, wherein said battery is arranged inside said power source accommodation hole, and wherein said conductive strip is used to electrically connect said battery and said circuit board;

a proximity sensor module arranged on said circuit board and used to sense an induction signal;

a control module arranged on said circuit board, electrically connected with said backlight module and said proximity sensor module, and used to turn on/off said backlight module according to said induction signal;

at least one bottom cover removably covering said power source accommodation hole from said lower surface of said baseplate; and

a top cover arranged on said upper surface of said baseplate, covering at least said backlight module and said power module, and having at least one light-permeable region above said backlight module.

2. The wireless light board according to claim 1, wherein at least one snap-fit hole is arranged at said positioning portion.

3. The wireless light board according to claim 2, wherein a light board fixing component is arranged below said snap-fit hole and fixed to said snap-fit hole detachably.

4. The wireless light board according to claim 3, wherein at least one snap-fit hook protrudes from an upper surface of said light board fixing component, snap-fitted into said snap-fit hole and fastening said light board fixing component and said baseplate together.

5. The wireless light board according to claim 1, wherein said backlight module includes a light-guide plate and a plurality of light-emitting elements, wherein said light-guide plate is arranged above said circuit board, and said light-emitting elements are arranged on said circuit board and at two sides of said light-guide plate.

6. The wireless light board according to claim 1, wherein said proximity sensor module is an inductive proximity sensor, a capacitive proximity sensor, a photoelectric proximity sensor, a contactless touch sensor, or a magnetic sensor.

7. The wireless light board according to claim 6, wherein said proximity sensor module is said magnetic sensor, and a magnet is installed in the door of the vehicle or in said wireless light board.

8. The wireless light board according to claim 1, wherein a flange is arranged along a rim of said power source accommodation hole on said lower surface and protrudes downward, and wherein said bottom cover has a sealing groove to snap fit to said flange.

9. The wireless light board according to claim 1, wherein said top cover is a digitally-printed inscription plate.

10. The wireless light board according to claim 1 further comprising a laser-optical plastic board arranged above said top cover, wherein a stainless steel board is arranged on said baseplate to expose a portion of said laser-optical plastic board.

11. The wireless light board according to claim 1, wherein overall thickness of said wireless light board is smaller than 5 mm and greater than 3 mm.

12. The wireless light board according to claim 1, wherein a level difference is formed between a lower surface of the main body of said baseplate and a lower surface of said recess.
