Abstract

A LED lamp includes an LED module and thermo-conductive members. The LED module has a transparent base, a plurality of LEDs mounted on the transparent base and a transparent film covering the LEDs. The transparent base has thermo-conductive sections and electro-conductive sections. The thermo-conductive members are attached on the thermo-conductive sections. Thereby, the invention can omnidirectionally emit light and has great effect of heat dissipation.

Claims

1. A light emitting diode (LED) lamp with a heat dissipation structure, comprising:

an LED module, having a transparent base, a plurality of LEDs mounted on the transparent base and a transparent film covering the LEDs, wherein the transparent base comprises thermo-conductive sections and electro-conductive sections; and

a plurality of thermo-conductive members, attached on the thermo-conductive sections.

2. The LED lamp of claim 1, further comprising thermo-conductive films attached on the thermo-conductive sections, wherein the thermo-conductive members are separately attached on the thermo-conductive films.

3. The LED lamp of claim 1, wherein each of the thermo-conductive members comprises clamps separately fastening on the thermo-conductive sections of the transparent base.

4. The LED lamp of claim 3, wherein the clamp comprises a pair of clamping sheets and an extension sheet connecting the clamping sheets, and an insertion space is formed between the clamping sheets for receiving the transparent base.

5. The LED lamp of claim 4, wherein the extension sheet is perpendicular to the transparent base to dispose a surface of the LEDs.

6. The LED lamp of claim 1, wherein the thermo-conductive member comprises a fin module and clamps connected to the fin module, and the clamps are attached on the thermo-conductive sections of the transparent base.

7. The LED lamp of claim 6, wherein the fin module is formed with an aperture corresponding to the LED module, and the LED module is secured in the aperture by the clamps.

8. The LED lamp of claim 6, wherein the clamp comprises a pair of clamping sheets and an extension sheet connecting the clamping sheets of the transparent base, and the transparent base is clamped between the clamping sheets

9. The LED lamp of claim 8, wherein the extension sheet is parallel to the transparent base to dispose a surface of the LEDs.

10. The LED lamp of claim 8, wherein the extension sheet is formed with open holes, the fin module is formed with connecting holes, and the LED module is fixed in the fin module by separately securing fasteners in the open holes and the connecting holes.

11. The LED lamp of claim 1, further comprising a thermo-conductive silver layer which is formed on the thermo-conductive sections, and the thermo-conductive member is attached on the thermo-conductive silver layer.

12. The LED lamp of claim 1, wherein the thermo-conductive member is made of metal or glass fiber, the thermo-conductive member is provided with an opening, and the transparent base is fixed on the thermo-conductive member and the thermo-conductive sections are beside the opening.

13. The LED lamp of claim 12, wherein the LED module is multiple in number, and the opening corresponds to the LED modules in number and position.

14. The LED lamp of claim 13, the thermo-conductive member is provided with wires which electrically connect to the electro-conductive sections.

15. The LED lamp of claim 1, further comprising a reflector and a seat, the reflector surrounds the LED module, and the seat covers the reflector and the thermo-conductive member.

16. The LED lamp of claim 15, wherein the reflector comprises reflective cups corresponding to the LED modules in arrangement.

17. The LED lamp of claim 15, wherein the seat comprises an outer cover and a bottom cover connected thereto, the outer cover is formed with a hollow corresponding to the reflector, and the bottom cover is formed with a slot corresponding to the LED module.
