Abstract: A heat dissipation structure for LED lamp includes at least one mounting plate connected to and between a top and a bottom locating plate, and a roll-shaped heat radiating member arranged beneath the top locating plate. The mounting plate and the top and bottom locating plates each are provided with a metal layer, to which LEDs are welded. When the heat dissipation structure is assembled to a lamp holder to form an LED lamp and the LEDs are lightened, heat produced by the LEDs is radiated from the metal layers and the heat radiating member, which together provide a large heat radiating area; meanwhile, perforations on the top locating plate allow convection of air in the LED lamp, and openings provided on the lamp holder allow exchange of air inside and outside the LED lamp, allowing the LED lamp to have reduced volume and increased heat dissipation efficiency.

Abstract: A light-emitting-diode (LED) lamp includes a control circuit board having a control circuit and a plurality of insertion holes provided thereon; a plurality of LED units, each of which including a circuit board, a plurality of LEDs mounted on the circuit board, and terminals provided at an end of the circuit board for plugging into the insertion holes on the control circuit board to thereby electrically assemble the LED unit to the control circuit board; and a glass bulb or tube for receiving the assembled control circuit board and LED units to complete the LED lamp that can be mounted to a general lamp holder. When electricity is supplied to the LED lamp, the LEDs are driven by the control circuit to emit light for illumination. The number of LED units and of the LEDs may be adjusted according to desired illuminance.
