Abstract

A lighting device includes a housing including a hole; a light source body including a light emitting module with a terminal; and electrical connection means including a portion projecting through the hole and having a connector electrically connected to the terminal and physically connecting the housing with the light source body.

First claim

The invention claimed is:

1. A lighting device comprising:
a housing having a hole;
a light source body which is disposed under the housing and includes a terminal;
a light emitting module which is disposed in the light source body; and
a socket which at least one portion is coupled to the hole of the housing and comprises a connector electrically connected to the terminal,
wherein the light source body includes a top surface, a bottom surface, and a first side between the top surface and the bottom surface,
wherein the light emitting module is provided on the bottom surface of the light source body,
wherein the lighting device further includes an end cap coupled to the first side of the light source body, and
wherein the end cap has an opening, and wherein the at least one portion of the socket is provided in the opening of the end cap.

2. The lighting device of claim 1 , wherein the light source body has a recess having a shape corresponding to the socket, wherein the terminal of the light source body is disposed within the recess, and wherein the socket comprises a hook which is coupled to the hole of the housing.

3. The lighting device of claim 1 , wherein the socket comprises:
a catching projection which is disposed in the light source body; and
a connecting portion which is disposed perpendicular to the catching projection.

4. The lighting device of claim 1 , further comprising a clip which is disposed on the housing, projects inwardly from the housing and fixes the light source body to the housing.

5. The lighting device of claim 1 , further comprising a connecting means which physically connects the housing with the light source body, wherein the light source body comprises a lower body and an upper body disposed on the lower body, wherein the connecting means is a coupler, wherein the coupler comprises a horizontal portion and a vertical portion which has a screw shape and is disposed perpendicular to the center of the horizontal portion, wherein the lower body has a horizontal recess in which the horizontal portion of the coupler is disposed, wherein the upper body has a through-hole through which the vertical portion of the coupler passes, and wherein the vertical portion of the coupler is screw-coupled to housing, so that the light source body is coupled to the housing.

6. The lighting device of claim 1 , further comprising a connecting means which physically connects the housing with the light source body, wherein an insertion member is disposed on one side of the light source body, wherein the connecting means is a fixing box, wherein the fixing box is disposed on the housing and comprises an elastic body and a support, wherein the insertion member is coupled to the fixing box and contacts with the elastic body of the fixing box, and wherein the support supports the insertion member.

7. The lighting device of claim 1 , further comprising a connecting means which physically connects the housing with the light source body, wherein the light source body comprises a catching projection formed on both sides thereof, wherein the connecting means is a fastener, wherein the fastener comprises a rotating member comprising a first hinge and a second hinge, a fixing member coupled to the first hinge and the housing, and a settling member of which one end is coupled to the second hinge and of which the other end is coupled to the light source body, and wherein the fastener is disposed on both sides of the light source body.

8. The lighting device of claim 1 , further comprising a connecting means which physically connects the housing with the light source body, wherein the connecting means is a fastener, wherein the fastener comprises a first coupling portion coupled to a side of the light source body, a second coupling portion coupled to the housing, and a connecting portion connecting the first coupling portion with the second coupling portion, wherein the second coupling portion has a horizontal hole, wherein an opening is disposed in the housing, wherein the housing comprises a projection disposed in the opening of the housing, wherein the fastener is disposed on both sides of the light source body, and wherein the projection has a shape corresponding to the horizontal hole and is coupled to the horizontal hole.

9. The lighting device of claim 1 , further comprising a connecting means which physically connects the housing with the light source body, wherein the connecting means is a connection member, wherein the connection member comprises a lower member coupled to the side of the light source body, an upper member coupled to the housing, and a connection portion which connects the lower member with the upper member, and wherein the housing has a hole extending in one direction.

10. The lighting device of claim 1 , wherein the socket comprises a horizontal portion which is disposed on the top surface of the housing, and a vertical projection which is connected to the horizontal portion and passes through the hole of the housing and then is connected to the light source body, and wherein the connector is disposed in the vertical projection of the socket.

11. The lighting device of claim 10 , wherein a plurality of the light source bodies are provided, and wherein the end cap is coupled to the first sides of the plurality of the light source bodies, and wherein the vertical projection of the socket is connected to the opening, and then is electrically connected to the terminal.

12. The lighting device of claim 10 , wherein the terminal of the light source body has a projecting shape, wherein the vertical projection of the socket has a receiving recess in which the terminal is disposed, and wherein the connector is disposed in the receiving recess.

13. The lighting device of claim 1 , wherein the light emitting module comprises:
a first light emitting module which is disposed in the light source body; and
a second light emitting module which is disposed adjacent to the first light emitting module,
wherein an optical efficiency of the first light emitting module is better than that of the second first light emitting module.

14. The lighting device of claim 13 , wherein the light source body further comprises a heat radiating structure, and wherein the heat radiating structure is disposed on the first light emitting module.

15. The lighting device of claim 13 , wherein the light source body comprises a first heat radiating structure and a second heat radiating structure, wherein the first heat radiating structure is arranged on the first light emitting module, and the second heat radiating structure is arranged on the second first light emitting module, and wherein an arrangement density of the first heat radiating structure is higher than that of the second heat radiating structure.

16. A lighting device comprising:
a housing having a hole;
a light source body which is disposed under the housing and includes a terminal;
a light emitting module which is disposed in the light source body; and
a socket comprising a first part inserted into the hole of the housing, a second part extended from the first part and disposed on the housing, and a third part coupled to the first part and disposed in the housing,
wherein the socket comprises a connector electrically connected to the terminal of the light source body and disposed in the third part,
