Abstract

A ventilator illumination device, including a light-emitting module for housing a light-emitting unit and a power box module for housing a power supply supplying direct current for the light-emitting unit, wherein an anti-reversal installation structure is provided on the light-emitting module and the power box module, the anti-reversal installation structure limiting the light-emitting unit to be installed only in a state that the light-emitting unit faces towards one predetermined direction. The illumination device is easy to install and prevents inversion of the light-emitting unit, thus ensuring proper brightness of the light irradiated by the light-emitting unit into the room.

First claim

What is claimed is:

1. A ventilator illumination device, comprising a light-emitting module for housing a light-emitting unit and a power box module for housing a power supply supplying direct current for the light-emitting unit, wherein,
an anti-reversal installation structure is provided on the light-emitting module and the power box module, the anti-reversal installation structure limiting the light-emitting unit to be installed only in a state that the light-emitting unit faces towards one predetermined direction,
wherein the light-emitting unit includes a lamp holder, a lamp tube and light-emitting chips arranged on one surface of the lamp tube, and the power box module comprises a power box body and a socket provided in the power box body for insertion of the lamp holder of the light-emitting unit;
the anti-reversal installation structure comprises a half-circle flange provided on the lamp holder of the light-emitting unit near to the lamp tube and protruding lugs provided on one surface of the power box body near to the light-emitting module,
wherein a positioning element, which extends towards the light-emitting module over a distance shorter than the protruding lugs, is disposed on the bottom of the one surface of the power box body near the light-emitting module, and an empty gap separates the positioning element from the flange of the lamp holder of the light-emitting unit when the lamp holder of the light-emitting unit is inserted into the socket;
wherein both the positioning element and the protruding lugs hold the lamp holder.

2. The ventilator illumination device according to claim 1 , wherein the flange is located at the bottom of the lamp holder of the light-emitting unit, the protruding lugs are provided at the top of the power box body, and a projection of the protruding lugs in a horizontal projection plane extends over a projection of the power box body in the horizontal projection plane.

3. The ventilator illumination device according to claim 1 , wherein the flange is located at the top of the lamp holder of the light-emitting unit, the protruding lugs are provided at the bottom of the power box body, and a projection of the protruding lugs in a horizontal projection plane extends over a projection of the power box body in the horizontal projection plane.

4. The ventilator illumination device according to claim 1 , wherein the anti-reversal installation structure comprises a protrusion provided on a surface of the lamp holder of the light-emitting unit opposite to the socket and a recess or opening provided in the socket and configured to correspond to the protrusion.

5. The ventilator illumination device according to claim 1 , wherein the anti-reversal installation structure comprises a recess or opening provided in a surface of the lamp holder of the light-emitting unit opposite to the socket and a protrusion provided on the socket and configured to be snapped into the recess or opening.

6. The ventilator illumination device according to claim 1 , wherein the flange is formed in a discontinuous form.

7. The ventilator illumination device according to claim 2 , wherein the flange is formed in a discontinuous form.

8. The ventilator illumination device according to claim 3 , wherein the flange is formed in a discontinuous form.

9. The ventilator illumination device according to claim 1 , wherein the half-circle flange is formed on an exterior surface of the light-emitting module.

10. The ventilator illumination device according to claim 1 , wherein the protruding lugs and the positioning element each extends from said one surface of the power box body.
