Title:
SPOT LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP3910543
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a spot lighting fixture whose light emitting diode has improved luminance since the heat generated in the light emitting diode is radiated to the outside effectively.
SOLUTION: The spot lighting fixture A has the light emitting diode 110 which is mounted on a substrate 100, an inverse cone shape reflecting plate 200 holding the light emitting diode 110 inside, which reflects the light of the light emitting diode 110 forward, and a thermally conductive member 300 which is mounted between the substrate 100 and the reflecting plate 200. Radiating fins 240 which radiate the heat conducted from the light emitting diode 110 via the substrate 100 and the heat conductive member 300 are formed on an outer periphery of the reflecting plate 200.
