Patent ID: 8354780

Claim:
A lamp device comprising: a housing having opposite first and second sides, and formed with a plurality of heat-dissipating holes; a conductive connecting head mounted on said first side of said housing; a first heat-conducting member mounted on said second side of said housing, said first heat-conducting member having a first side surface exposed outward of said housing, and a second side surface opposite to said first side surface and disposed in said housing; a lighting unit thermally contacting and mounted on a said first side surface of said first heat-conducting member; a first heat-dissipating layer made of an infrared radiating material, said first heat-dissipating layer thermally contacting and being disposed on said second side surface of said first heat-conducting member; and a transparent cap body mounted on said second side of said housing for covering said lighting unit; wherein heat generated by said lighting unit is transmitted by said first heat-conducting member to said first heat-dissipating layer, and is dissipated by said first heat-dissipating layer through said heat-dissipating holes in said housing.
