Abstract

An illumination apparatus for vehicle including at least one light source, a light valve, an optical wavelength conversion layer, and a projection lens set is provided. The at least one light source provides a light beam. The light valve is disposed on the transmission path of the light beam. The light valve controls a light shape of at least a portion of the light beam. The optical wavelength conversion layer is disposed on the transmission path of the at least a portion of the light beam and includes a plurality of optical wavelength conversion units for converting the at least a portion of the light beam into an illumination light beam. The projection lens set is disposed on a transmission path of the illumination beam and configured to project the illumination beam. The optical wavelength conversion layer is located between the light valve and the projection lens set.

Description

Technical field [0001] The present invention relates to a lighting device, and in particular to a vehicle lighting device. Background technique [0002] Recently, headlights based on solid-state light sources such as light-emitting diodes (LEDs) and laser diodes (laserdiodes) have gradually gained a place in the market. The luminous efficiency of light-emitting diodes is between 5%-8%, which has different color temperatures to choose from and has excellent power saving benefits. On the other hand, because laser diodes have a luminous efficiency higher than about 20%, in order to break through the light source limitation of light-emitting diodes, laser light sources are gradually developed to excite phosphors to produce applicable high-efficiency light sources. These two forms are the current mainstream light sources of solid-state lighting. [0003] In addition, the headlight light source module using the laser light source can not only use the laser light source to excite the ph...
