Abstract

An LED lamp assembly includes an LED lamp and a driving circuit module mounted on the LED lamp. The LED lamp includes an airproof chamber. A plurality of LED modules is received in the airproof chamber. A gasbag is located at the driving circuit module and communicates with the airproof chamber of the LED lamp. The gasbag receives air from the airproof chamber when the LED modules are activated to lighten and heat the airproof chamber.

Claims

1. An LED lamp assembly comprising:

an LED lamp comprising an airproof chamber, a plurality of LED modules received in the airproof chamber; and

a driving circuit module mounted on the LED lamp, a gasbag located at the driving circuit module and communicating with the airproof chamber of the LED lamp, the gasbag receiving air from the airproof chamber when the LED modules are activated to lighten.

2. The LED lamp assembly as claimed in claim 1, wherein the driving circuit module comprises a hermetical first chamber communicating with the airproof chamber of the LED lamp and a second chamber communicating with ambient air, the gasbag being located at the second chamber of the driving circuit module and communicating with the first chamber.

3. The LED lamp assembly as claimed in claim 2, wherein the driving portion comprises an annular main body and an engaging plate fittingly received in the main body to divide the main body into two opposite portions, one baffling plate being closed to one portion of the main body to define the first chamber with the engaging plate, another baffling plate being closed to another portion of the main body to define the second chamber with the engaging plate.

4. The LED lamp assembly as claimed in claim 3, wherein a plurality of slots is defined in the main body corresponding to the second chamber to make the second chamber communicate with the ambient air.

5. The LED lamp assembly as claimed in claim 3, wherein a tube extends through the engaging plate and connects the first chamber with the gasbag.

6. The LED lamp assembly as claimed in claim 3, wherein a driving module is mounted in the first chamber of the driving portion of the driving circuit module to electronically connect with the LED modules.

7. The LED lamp assembly as claimed in claim 3, wherein the driving circuit module further comprises a connecting portion extending from the driving portion and hermetically connecting with the airproof chamber of the LED lamp.

8. The LED lamp assembly as claimed in claim 7, wherein the connecting portion defines a through hole therein to make the connecting portion communicate with the first chamber of the driving portion and the airproof chamber of the LED lamp via the connecting portion.

9. The LED lamp assembly as claimed in claim 1, wherein the LED lamp comprises a heat sink, a frame mounted on the heat sink, a cover mounted in frame, and a pressing member pressing the cover to the frame, the LED modules being mounted on the heat sink, and the heat sink, the frame, the cover, and the pressing member cooperatively defining the airproof chamber.

10. The LED lamp assembly as claimed in claim 9, wherein the driving circuit module is mounted on a side of the heat sink and communicates with the airproof chamber of the LED lamp.
