Patent ID: 8172425

Claim:
A low-profile light-emitting diode (LED) lamp, comprising: a base, which forms a base opening, the base having an inner surface that forms a first rib and holes, the first rib extending around and located outboard the base opening, the holes being located outboard the first rib, the base having an outer surface on which a second rib that is set around and located outboard the base opening is formed; a cover, which forms a cover opening corresponding to the base opening, the cover having an inner surface which defines a first slot corresponding to the first rib and forms posts respectively corresponding to the holes for mating each other, the base and the cover being fixed together by mating the holes and the posts to each other, the inner surface of the cover forming a third slot that extends along and located between the cover opening and the first slot; a heat dissipation plate, which has an inner surface that forms a second slot corresponding to and mating the second rib, the heat dissipation plate having an outer surface that forms a plurality of raised portions, a convection chamber being formed between each of the raised portions and the outer surface of the heat dissipation plate; an LED module, which comprises a carrier board and at least one LED element mounted to the carrier board, the carrier board being set on the inner surface of the heat dissipation plate and retained within the base opening; a circuit board, which forms a plurality of through holes corresponding to the LED elements to respectively receive the LED elements therethrough, the circuit board being set inside the first rib of the base, the LED module and the circuit board being electrically connected to each other; and a light guide hood, which comprises a light guide section and a flange formed on a circumference of the light guide section, the flange forming a third rib corresponding to and mating the third slot of the cover.
