ILLUMINATION DEVICE AND PROJECTION TYPE DISPLAY DEVICE

摘要

PURPOSE: A light device is provided to increase the amount of output light by reflecting and reflecting light of light sources again. CONSTITUTION: At least one light source includes a light emitting layer(12-3) and a light reflecting layer(12-2). A reflecting cover is made of an inner surface with the reflecting layer. At least one light source is mounted on the inner surface. The reflecting cover surrounds at least one light source to reflect and reflect light again. A dichroic coating layer(14) selectively reflects light of a specific wavelength. A wavelength converting layer(13) converts the first wavelength of incident light into a second wavelength.
