Abstract
An LED-based lamp comprises a contact base, an LED support plate, a circuit board supported by the LED support plate, LEDs mounted to the circuit board, a heat transferring structure, a heat dissipating structure, a reflector and a bulb cover enclosing the circuit board, the LEDs, the LED support plate and the reflector. The LED support plate and the heat dissipating structure each dissipate a portion of the heat generated by LEDs. The heat transferring structure thermally couples the LED support plate to the heat dissipating structure and distributes the heat dissipation between them. The LEDs are oriented to project light in a first direction along a vertical axis of the LED-based lamp. A reflector is positioned in the first direction to diffuse light from the LEDs such that a majority portion of the light is directed in a second direction away from the first direction.
