LASER LIGHTING DEVICE

摘要

The present invention relates to a laser lighting device. The device includes a laser diode (10) generating a light source having strong directivity; a filter (20) penetrating blue light (not more than 460mm) in the light source from the laser diode (10); a color transformation plate (30) emitting light in both directions by transforming the color of the light source passing through the filter; and a reflecting plate (40) surrounding the filter (20) to correspond to an emission direction of the light, and controlling a direction in which the light, transformed by the color transformation plate (30), goes forward. According to the present invention, the color transformation plate is placed on a rear surface of a short-wavelength penetration filter, and the blue light emitted from the light source passes through the filter to form the color transformation by the color transformation plate, but the blue light goes forward through the short-wavelength penetration filter and a shape of the beam is controlled by the reflecting plate, and therefore, candela of the lighting device is improved, and as a semiconductor light emitting element uses laser to the light source generating light, more excited light is collected than an LED so that higher brightness and output are possible for the lighting device.
