Abstract

The present disclosure relates to an illuminating apparatus which is received at the back of an outer surface and which includes: a lighting part having a front surface, through which the light is irradiated, and a rear surface, which is the back side of the front surface; an electric connector electrically connected to the lighting part and coupled to a power supply at the back of the outer surface; and a length-adjustable shaft provided between the lighting part and the electric connector and bringing the rear surface of the lighting part into contact with the outer surface.

Claims

1. An illuminating apparatus, which is received at the back of an outer surface, wherein the illuminating apparatus comprises:

a lighting part having a front surface, through which the light is irradiated, and a rear surface, which is the back side of the front surface;

an electric connector electrically connected to the lighting part and coupled to a power supply at the back of the outer surface; and

a length-adjustable shaft disposed between the lighting part and the electric connector and bringing the rear surface of the lighting part into contact with the outer surface,

wherein the length-adjustable shaft comprises a lower shaft part coupled to the rear surface and an upper shaft part coupled to the electric connector, and wherein the lower shaft part is urged by a spring to move toward the upper shaft part, whereby the length of the length-adjustable shaft is adjusted.

2. The illuminating apparatus as claimed in claim 1, wherein the relative movement of the lower shaft part to the upper shaft part is guided by a projection and a projection guide slot.

3. The illuminating apparatus as claimed in claim 1, wherein the illuminating apparatus further comprises a stopper for stopping the relative movement of the lower shaft part to the upper shaft part.

4. The illuminating apparatus as claimed in claim 3, wherein the stopper stops the relative movement through the relative rotation of the lower shaft part to the upper shaft part.

5. The illuminating apparatus as claimed in claim 4, wherein the electric connector is a socket base rotatably coupled to the power supply, and wherein the direction of the relative rotation is opposite to the rotational direction of the socket base.

6. The illuminating apparatus as claimed in claim 2, wherein the illuminating apparatus further comprises a projection receiving part which communicates with the projection guide slot and receives the projection during the relative rotation of the lower shaft part to the upper shaft part.

7. The illuminating apparatus as claimed in claim 6, wherein the illuminating apparatus further comprises a projection hooking part disposed between the projection guide slot and the projection receiving part.

8. The illuminating apparatus as claimed in claim 7, wherein the electric connector is a socket base rotatably coupled to the power supply, and wherein the direction of the relative rotation is opposite to the rotational direction of the socket base.

9. The illuminating apparatus as claimed in claim 8, wherein the lighting part is an LED lighting part.
