| 摘要 |
White light that was emitted from a white light source and converged through a condenser lens enters a light guide with a maximum incidence angle alpha. Since excitation light emitted from an excitation light source is adjusted by the adjustment optical system for its beam diameter, it enters the light guide with a maximum incidence angle beta (beta<alpha) after being converged by the condenser lens. Then, a motion mechanism displaces a second lens in an adjustment optical system in the direction of the optical axis to vary the beam diameter and the maximum incidence angle beta of the excitation light, whereby a divergence angle of the excitation light emitted through a light distribution lens is made to correspond to the divergence angle of the visible light. |
