LIGHTING APPARATUS USING LIGHT EMITTING DIODE

摘要

PURPOSE: A lighting device using a light emitting diode is provided to implement illumination like an incandescent lamp with low power by forming a diffused reflection surface in the central part of the lighting device. CONSTITUTION: A light emitting diode(10) is mounted on a printed circuit board. A light guide(20) includes an accommodating chamber and a supporting part. The light guide transmits the light generated from the light emitting diode. A diffusion lens(30) includes a first surface and a second surface. The second surface has a diffused surface(33).
