    摘要： A lighting device including a light guide plate, a light source unit disposed on the side of the light guide plate and a polarization separation element disposed between the light guide plate and the light source unit. The polarization separation element is used for transmitting linearly polarized light in a first polarized direction and reflecting linearly polarized light in a polarized direction normal to the first polarized direction. The light source unit includes a pillar-shaped light guide which light exits at a first side surface, a spot light emission source disposed on the end surface of the pillar-shaped light guide, and a reflecting layer disposed on a second side surface of a prism surface opposed to the first side surface for reflecting light from the spot light emission source.

    摘要： A prismatic light-guide plate has a prismatic surface, which is provided with a plurality of prisms that reflect light that is incident from a light-incident end thereof, and an emission surface opposite to the prismatic surface, which completely reflects the light that is incident thereto to propagate the same, and which also emits emitted light that is reflected from the prisms. The prismatic light-guide plate has scattering portions provided in a region of the emission surface that emits the emitted light at a high density, for scattering the emitted light and broadening an angle of view of light.

    摘要： A light guide member illuminates with uniform light intensity distribution using the point light source light. On the lower end of the light guide member having a pair of side faces disposed oppositely, a groove is provided for receiving light output from each point light source and diffusing the above received light to at least three directions from the incident side toward the output side. Light components having directions using side-face reflection are generated in the light guide member, enabling light output to multiple directions from the cylindrical-shaped light guide member, and uniform illumination over a wide range. By using the ring-shaped light guide member, cost reduction is effectively achieved, and miniaturization of the illumination mechanism and the image capturing mechanism can also be attained.
