[0005] In the plastic-coated aluminum LED lamp, the upper cap is a plastic-coated aluminum shell, an outer layer of the shell being a plastic element, an inner layer thereof being an aluminum cup, and an inner side of an outer edge of the aluminum cup being provided with an L-shaped step for accommodating the LED lamp panel.

[0006] In the plastic-coated aluminum LED lamp, the LED lamp panel and the aluminum cup are connected by interference fit.

[0007] In the plastic-coated aluminum LED lamp, a joint between the LED lamp panel and the aluminum cup is provided with glue.

[0008] In the plastic-coated aluminum LED lamp, the LED lamp panel comprises an aluminum substrate and LED beads adhered on the aluminum substrate.

[0009] In the plastic-coated aluminum LED lamp, the bulb shell is clamped on the plastic element of the upper cap.

[0010] In the plastic-coated aluminum LED lamp, the bulb shell is adhered on the plastic element of the upper cap.

[0011] The LED lamp according to the present invention has simple and reliable structure, is conveniently to assemble, has high efficiency, and is suitable for automation and large-scale production. Therefore, the costs of materials and production may be greatly reduced, and large-scale application of energy-saving and environmentally-friendly illumination is greatly promoted.

DETAILED DESCRIPTION

[0014] The present invention is further described with reference to the accompanying drawings.

[0015] A plastic-coated aluminum LED lamp comprises: a lamp holder 1, an upper cap 2, a bulb shell 3, an LED lamp panel 6 and a drive power supply 8, the lamp holder 1 being thread-connected to the upper cap 2, wherein the LED lamp panel 6 is provided with a small separator 7, two ends above the small separator 7 being each provided with a rib 13, the rib 13 being provided with a slot 14 for accommodating a PCB of the drive power supply, two barbs 16 each having an open slot 17 being provided beneath the small separator 7 and being inserted in jacks on the LED lamp panel, thereby fixing the drive power supply; and the small separator located in the middle of the open slot 17 is provided with wiring holes 15, and for reduce the processes, and the drive power supply is connected to the LED lamp panel by two pins (pins 11 of the electrolytic capacitor) of an electrolytic capacitor 9 on the PCB of the drive power through the wiring hole.

[0016] The upper cap 2 according to the present invention is a plastic-coated aluminum shell, an outer layer of the shell being a plastic member 4, and an inner layer thereof being an aluminum cup 5. The LED lamp panel and the aluminum cup are connected by interference fit through an L-shaped step arranged on an inner side of an outer edge of the aluminum cup, and a joint between the LED lamp panel 6 and the aluminum cup may be provided with glue 12 to enhance the stability thereof; wherein the bulb shell is clamped or adhered on the plastic element of the upper cap.

[0017] The LED lamp panel according to the present invention comprises an aluminum substrate and LED beads adhered on the aluminum substrate.

[0018] During assembly, the small separator is clamped on the LED lamp panel through the barbs, the PCB of the drive power supply is inserted into the slot on the small separator, two pins of the electrolytic capacitor are made pass through the wiring holes in the barbs of the small separator, the two pins are afterwards tipped over and then welded on the LED lamp panel, and then the LED lamp panel is tightly pressed into the aluminum cup of the upper cap and then glue is applied thereto. Finally, the lamp holder is assembled and the bulb shell is clamped thereto. In this case, the assembly of the entire lamp is complete.
