Abstract

A lighting apparatus may include a body having a substrate, and a light emitting module with a light emitting diode (LED) mounted to the substrate. A connection member may be provided to the body, and a support member may be mounted to the connection member at a predetermined tilt angle thereto to adjust a light directing angle of the body.

Claims

1. A lighting apparatus comprising:

a body having a substrate, a light emitting module with a light emitting diode (LED) mounted to the substrate, and a heat sink to dissipate heat from the light emitting module;

a connection member provided to the body; and

a support member mounted to the connection member at a predetermined tilt angle,

wherein the connection member includes a first stopper to prevent the body from moving beyond a first tilt position relative to the support member, and the connection member includes a second stopper to prevent the body from moving beyond a second tilt position relative to the support member, wherein the light emitting module to provide the light in a first light direction when the body is in the first tilt position relative to the support member, and the light emitting module to provide light in a second light direction when the body is in the second tilt position relative to the support member.

2. The lighting apparatus of claim 1, wherein the support member includes:

a first contact to contact the first stopper and to prevent the body from moving beyond the first tilt position relative to the support member, and

a second contact to contact the second stopper and to prevent the body from moving beyond the second tilt position relative to the support member.

3. The lighting apparatus of claim 1, wherein the first stopper and the second stopper have different slope angles.

4. The lighting apparatus of claim 1, wherein the connection member further includes a first projection portion, and the support member further includes a second projection portion to engage with the first projection portion for adjusting a position of the body relative to the support member.

5. The lighting apparatus of claim 4, wherein the first projection portion includes a first plurality of projections spaced at intervals on the connection member, and the second projection portion includes a second plurality of projections spaced at intervals on the support member.

6. The lighting apparatus of claim 5, wherein the first plurality of projections includes a first total number of projections and the second plurality of projections includes a second total number of projections.

7. The lighting apparatus of claim 1, wherein one of the connection member and the support member includes an inserting projection, and the other one of the connection member and the support member includes a recess to engage with the inserting projection for adjusting a position of the body relative to the support member.

8. The lighting apparatus of claim 1, wherein the connection member includes a first recess and an inserting projection provided in the first recess, and

the support member includes a surrounding projection to be provided in the first recess, and a second recess provided within the surrounding projection, the second recess to receive the inserting projection.

9. The lighting apparatus of claim 8, further comprising a screw that passes through the second recess and attaches to the inserting projection.

10. The lighting apparatus of claim 8, wherein a first contact and a second contact are provided on surfaces of the support member that extend from the surrounding projection, the first contact and the second contact for contacting the first stopper and the second stopper, respectively.

11. The lighting apparatus of claim 10, wherein the first stopper is provided on a first surface of the first recess and the second stopper is provided on a second surface of the first recess.

12. The lighting apparatus of claim 10, wherein the first stopper and the second stopper have different slope angles.

13. The lighting apparatus of claim 1, further comprising a power supply unit to electrically connect to the light emitting module, and

a cable to pass through the connection member and the support member to connect the power supply unit to the light emitting module.

14. A lighting apparatus comprising:

a body having a light emitting module with a light emitting diode (LED);

a connection member to couple to the body, the connection member including a first stopper and a second stopper; and

a support member to couple to the connection member and provide the body at a specific tilt angle, the support member including a first contact and a second contact,

wherein the first stopper stops movement of the body relative to the support member when the first stopper contacts the first contact, and the second stopper stops movement of the body relative to the support member when the second stopper contacts the second contact, wherein the light emitting module to provide light in a first light direction when the body is in a first tilt position relative to the support member, and the light emitting module to provide light in a second light direction when the body is in a second tilt position relative to the support member.

15. The lighting apparatus of claim 14, wherein the connection member further includes a first plurality of projections, and the support member further includes a second plurality of projections to engage with the first plurality of projections for adjusting a position of the body relative to the support member.

16. The lighting apparatus of claim 15, wherein the first projection portion includes a first plurality of projections spaced at intervals on the connection member, and the second projection portion includes a second plurality of projections spaced at intervals on the support member.

17. The lighting apparatus of claim 14, wherein the connection member includes a first recess and an inserting projection provided in the first recess, and the support member includes a surrounding projection and a second recess provided within the surrounding projection, the second recess to receive the inserting projection.

18. The lighting apparatus of claim 17, further comprising a screw that passes through the second recess and attaches to the inserting projection.

19. The lighting apparatus of claim 17, wherein the first contact and the second contact are provided on surfaces of the support member that extend from the surrounding projection, the first contact and the second contact for contacting the first stopper and the second stopper, respectively.

20. The lighting apparatus of claim 14, further comprising power supply unit to electrically connect to the light emitting module, and

a cable to pass through the connection member and the support member to connect the power supply unit to the light emitting module.
