Abstract

An LED lamp is provided. The LED lamp includes a heat radiation member having a cavity therein; an LED module disposed in the cavity; a mounting frame disposed in the cavity and being above the LED module; and a lens mounted on the mounting frame.

Claims

1. An LED lamp, comprising:

a heat radiation member defining a cavity therein;

an LED module disposed in the cavity;

a mounting frame disposed in the cavity and being above the LED module;

a lens mounted on the mounting frame, comprising;

an upper ring;

a bottom plate having a through slot penetrated therethrough along an up and down direction; and

a plurality of connection rods each defining an upper end connected with the upper ring and a lower end connected with the bottom plate, the plurality of connection rods being spaced apart from each other along a circumferential direction of the mounting frame; and

a hook disposed on an outer circumferential surface of the lens for catching the mounting frame so as to mount the lens on the mounting frame, the hook being inserted between adjacent connection rods so as to catch the upper ring.

2. The LED lamp as set forth in claim 1, wherein the mounting frame has a mounting cavity therein, and the lens is mounted in the mounting cavity.

3. The LED lamp as set forth in claim 2, wherein a bottom surface of the lens is spaced apart from a bottom wall of the mounting cavity by a predetermined distance.

4. The LED lamp as set forth in claim 2, wherein a groove is formed in a circumferential wall of a top end of the cavity, an upper end of the lens is upwardly extended out of the mounting cavity, and an outer circumferential edge of the upper end of the lens is fitted in the groove.

5. The LED lamp as set forth in claim 4, wherein the upper end of the lens has a flange extended along a radial direction and fitted in the groove.

6. The LED lamp as set forth in claim 1, wherein the hook is V-shaped.

7. The LED lamp as set forth in claim 1, wherein a plurality of the hooks are provided and evenly spaced apart from each other along a circumferential direction of the lens.

8. The LED lamp as set forth in claim 1, wherein the hook and the lens are integral with each other.

9. The LED lamp as set forth in claim 1, wherein the hook abuts against each of the adjacent connection rods.

10. The LED lamp as set forth in claim 1, wherein the hook catches a lower surface of the upper ring,

wherein a contact surface of the hook contacting the lower surface of the upper ring, a bottom surface of the lens and the bottom plate are parallel with one another.

11. The LED lamp as set forth in claim 1, wherein the plurality of the connection rods, the upper ring and the bottom plate are integrally formed from a plastic material.

12. The LED lamp as set forth in claim 1, wherein a bottom wall of the cavity has a first wire hole penetrated therethrough in the up and down direction,

wherein the bottom plate has a second wire hole penetrated therethrough in the up and down direction and is corresponded to the first wire hole,

wherein a first wire groove is formed in an upper surface of the bottom plate communicated with the second wire hole.

13. The LED lamp as set forth in claim 12, wherein a column is disposed on a lower surface of the bottom plate and fitted within the first wire hole, and the second wire hole is penetrated through the column.

14. The LED lamp as set forth in claim 10, wherein a wire passing extension is disposed on an inner wall of the through slot and extended towards a center of the through slot,

wherein a second wire groove is formed in an upper surface of the wire passing extension and communicated with the first wire groove.

15. The LED lamp as set forth in claim 12, wherein a holding groove is formed in the bottom wall of the cavity,

a portion of the bottom plate is recessed downwardly with respect to a remaining portion of the bottom plate so as to form a first boss on a lower surface of the bottom plate and to form the first wire groove,

a portion of the wire passing extension is recessed downwardly with respect to a remaining portion of the wire passing extension so as to form a second boss on a lower surface of the wire passing extension and to form the second wire groove,

wherein the first boss and the second boss are received in the holding groove.

16. An LED lamp, comprising:

a heat radiation member defining a cavity therein;

an LED module disposed in the cavity;

a mounting frame disposed in the cavity and being above the LED module; and

a lens mounted on the mounting frame, wherein the mounting frame has a mounting cavity therein, and the lens is mounted in the mounting cavity, a bottom surface of the lens is spaced apart from a bottom wall of the mounting cavity by a predetermined distance.

17. The LED lamp as set forth in claim 16, wherein a groove is formed in a circumferential wall of a top end of the cavity, an upper end of the lens is upwardly extended out of the mounting cavity, and an outer circumferential edge of the upper end of the lens is fitted in the groove.

18. The LED lamp as set forth in claim 17, wherein the upper end of the lens has a flange extended along a radial direction and fitted in the groove.

19. The LED lamp as set forth in claim 16, further comprising at least one hook disposed on an outer circumferential surface of the lens for catching the mounting frame so as to mount the lens on the mounting frame, wherein the hook is V-shaped.

20. The LED lamp as set forth in claim 19, wherein the at least one hook comprises a plurality of the hooks, which are evenly spaced apart from each other along a circumferential direction of the lens, wherein the plurality of hooks and the lens are integral with each other.
