Abstract

A ceiling fan light LED assembly device, wherein a plurality of light-emitting bodies are disposed within light tubes, and a drive circuit within a mount disc directly actuates the light-emitting bodies to emit light. Furthermore, a reflecting protective cover having a light focusing and refracting effect is disposed on the mount disc, which is not only able to transmit light emitted by the light-emitting bodies H through the reflecting protective cover F 6, but is also able to transmit the light through an arched surface of the transparent shade I, thereby enhancing illumination effectiveness of the refracted light rays.

Claims (15)

1. A ceiling fan light LED assembly device comprising:

a light body having:

a) a locking disc;

b) a mount disc having:

i) a holding space;

ii) a drive circuit located in the holding space; and

iii) a pull chain switch located in the holding space and controlling the drive circuit;

c) a reflecting protective cover connected to a bottom of the mount disc;

d) a circular light mount connected to the bottom of the mount disc and having a groove;

e) a plurality of light emitting bodies located in the groove of the circular light mount, the plurality of light emitting bodies are electrically connected to and controlled by the drive circuit; and

f) a transparent shade connected to the bottom of the mount disc.

2. The ceiling fan light LED assembly device according to claim 1 , wherein the plurality of light emitting bodies transmit a light through the reflecting protective cover and the transparent shade.

3. The ceiling fan light LED assembly device according to claim 1 , wherein the circular light mount and the plurality of light emitting bodies are configured as a device selected from a group consisting of an emergency illumination light, a street light, and a desk light.

4. The ceiling fan light LED assembly device according to claim 1 , wherein the circular light mount is configured as a light-emitting light tube selected from a group consisting of a circular light tube, a curved light tube, a cylindrical light tube, a helical light tube, and a 2U/3U/4U light tube.

5. The ceiling fan light LED assembly device according to claim 1 , wherein the plurality of light emitting bodies display dynamic light emitting states selected from a group consisting of a prolonged constant light state, a gradually dimming and brightening varied light state, and a successively flashing bright and dim light state.
