Title:
LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2005174982
Kind Code:
A
Abstract:
To provide a lighting device in an integral structure in which generation of heat of a control unit does not affect a laser composite optical system.
Laser beams emitted from a plurality of laser light sources generating the laser beams different in wavelengths are synthesized in the laser composite optical system. The laser beam in the desired wavelength among the synthesized laser beams can be selected by an acoustic optical element 10. A driver 17 and a control substrate 19 for controlling the acoustic optical element 10 are thermally separated from the laser composite optical system and the acoustic optical element 10 and they are made into a unit.
