ABSTRACT:
An illumination apparatus includes a heat-conductive tubular housing. A lighting device includes: a heat dissipating plate positioned in the housing and disposed adjacent to an open front end of the housing; lighting units, each having a light emitting diode mounted on a circuit board in thermal contact with the heat dissipating plate, and a condensing member mounted on the circuit board and disposed around the light emitting diode; and a driving unit disposed fixedly in the housing, connected electrically to the circuit board, and coupled electrically to an external power source for activating the light emitting diodes. A seal washer is disposed among and abuts against the housing, a transparent plate in front of the lighting units, and an annular cap mounted on the front end of the housing, so as to establish a liquid-tight seal thereamong.
