Patent ID: 8164237

Claim:
A light emitting diode (LED) lamp with a flow guide function, for guiding an external air to dissipate heat from the LED lamp, and the LED lamp comprising: a lamp base, having a containing space, and a plurality of heat dissipating holes formed on the lamp base; a heat dissipating body, installed in the containing space, and including a plurality of heat dissipating fins, a heat dissipating passage defined between any two fins, and the heat dissipating passages being installed corresponding to the heat dissipating holes respectively; a heat dissipating plate, attached and coupled onto the heat dissipating body, and including a plurality of openings formed around the heat dissipating plate, and a flow guide plate formed at a lateral edge of each opening and extended from the heat dissipating plate, and provided for guiding external air into the heat dissipating passage and out from the heat dissipating holes; and an LED module, including a printed circuit board in a thermal contact with the heat dissipating plate and a plurality of LEDs electrically coupled to the printed circuit board.
