LIGHTING DEVICE AND CABINET

摘要

A lighting device is provided with a circuit board, a light source disposed on a lower surface of the circuit board, and a longitudinal light guide member. The light guide member has a light entrance portion formed on the upper end portion of the light guide member, and a light exit portion formed on the front surface of the light guide member. The lighting device is configured so that light emitted from the light source is introduced from the light entrance portion and reflected to the front side so as to be emitted from the light exit portion. The lighting device is additionally provided with a heat dissipating unit which is disposed along the circuit board and is thermally connected to the circuit board. At least a portion of the top surface of the heat dissipating unit is a heat dissipating surface that is not covered by the circuit board.
