SURFACE LIGHT EMITTING APPARATUS EMITTING LASER LIGHT |
摘要 |
A surface light emitting apparatus capable of providing uniform illumination while efficiently using a laser light. The apparatus comprises a light source section that includes at least one light source which emits laser beam; an optical guiding section that guides from an incidence surface of the optical guiding section the laser beam emitted from the light source section and emits the laser beam from a radiation surface of the optical guiding section; and an optical element section that includes at least one beam shaping optical element with a powered surface which converts an intensity distribution of the laser beam emitted from the light source section at the incidence surface of the optical guiding section to a uniform intensity distribution.
