Description

Technical Field

[0002] LED lights typically consist of a lamp holder, a lamp board, a driver, and a lamp cover. They offer advantages such as high luminous efficiency, long lifespan, low power consumption, environmental friendliness, and small size.

[0003] However, in the existing technology, the lamp board and the driver power supply are electrically connected and directly installed inside the LED lamp. Both the driver power supply and the lamp board generate heat during operation. Since the lamp board and the driver power supply are in the same cavity, the heat inside the LED lamp accumulates in the cavity and cannot be dissipated in time. This causes the LED lamp chip to be affected by heat and temperature, which can easily lead to light decay or even damage to the LED lamp chip, thereby affecting the lifespan of the LED lamp and reducing its practicality.

[0004] Therefore, this utility model provides an isolated heat-conducting LED lamp. Utility Model Content

[0024] In this embodiment, a groove is formed inside the top of the isolation plate 2. The groove is located on the top of the heat-conducting plate 7, and a driving power supply 6 is installed inside the groove. The driving power supply 6 is electrically connected to the lamp holder 1 through a wire. The isolation plate 2 is made of polyamide plastic material, and the lamp cover 3 is made of PC material. The driving power supply 6 is located on the top of the heat-conducting plate 7, and a first thermally conductive silicone sheet 12 is fixedly installed between the bottom of the driving power supply 6 and the heat-conducting plate 7.

[0026] In this embodiment, an inner groove is formed inside the bottom end of the heat-conducting sleeve 10. The top end of the lampshade 3 is inserted into the inner groove by adhesive.

This facilitates the timely discharge of heat generated inside the LED lamp, preventing the heat inside the LED lamp from affecting the driver power supply 6 and the lamp board 9, and avoiding any impact on the lamp board 9 and the LED chips and driver power supply 6 on its surface, thereby ensuring the lifespan of the LED lamp and improving its practicality; the insulating tube 13 has wires installed inside, and the driver power supply 6 and the lamp board 9 are electrically connected through the wires.
