ActiveUS20090086466A1High directivityEffectively focusIlluminated signsNon-linear opticsDirectivityLight guide
A planar light emitting element is capable of outputting light having high directivity in at least one direction. The planar light emitting element has a light guide plate and first and second low refractive index layers. Light incident on the light guide plate is totally reflected on the interface between the light guide plate and the second low refractive index layer, propagates in the light guide plate, and is output from the light guide plate to the first low refractive index layer through a light output opening section. When a refractive index of the first low refractive index layer is sufficiently smaller than a refractive index of the light guide plate, the light propagates in the light guide plate at a large angle with respect to a light output surface of the light guide plate. When the difference between the refractive indexes of the first and second low refractive index layers is small, a spreading angle of light output to the first low refractive index layer is small. The light having high directivity is reflected on a reflective mirror and output from the planar light emitting element.
