SOLID STATE LIGHT SOURCE DEVICE, AUTOMOTIVE LIGHTING USING SAME, IMAGE DISPLAY DEVICE, AND DRIVE METHOD FOR SOLID STATE LIGHT SOURCE DEVICE

摘要

A solid state light source device includes N (an integer of two or more) sets of solid state light source assemblies having a plurality of solid state light source cells arranged in a matrix pattern a multiple lens block including N incidence faces facing the N sets of solid state light source assemblies and causing light emitted from the solid state light source cells to be incident through multiple lens cells of a matrix pattern and one emission face composing the light incident from the N incidence faces and a dichroic filter that is obliquely arranged on the incidence faces inside the multiple lens block and selectively reflects or transmits incident light based on the incident light wavelength. Light distribution characteristics and color temperature of light exiting the emission face of the multiple lens block are controlled by a ratio of power supplied to the solid state light source cells.

1. A solid state light source device using solid state light sources as light emitting bodies, the solid state light source device comprising:
N (here, N is an integer of two or more) sets of solid state light source assemblies in which a plurality of solid state light source cells are arranged in a matrix pattern; a multiple lens block that includes N incidence faces facing the N sets of solid state light source assemblies and causing light emitted from the solid state light source cells to be incident through multiple lens cells of a matrix pattern and one emission face composing the light incident from the N incidence faces and causing composed light to exit through multiple lens cells of a matrix pattern; and a dichroic filter that is obliquely arranged on the incidence faces inside the multiple lens block and selectively reflects or transmits incident light based on a wavelength of the incident light, wherein light distribution characteristics and a color temperature of light exiting from the emission face of the multiple lens block to a light receiving unit are controlled by controlling a ratio of power supplied to the solid state light source cells.
