An illumination device can include a light source; and a light guiding lens for receiving light from the light source. The light guiding lens includes a light emission portion that extends in a predetermined direction and has a main surface with reflecting cuts, and a light guiding portion provided to the light emission portion at an end portion thereof in the predetermined direction. The light guiding portion is configured to project more than the light emission portion in a thickness direction of the light emission portion and extend along the end portion of the light emission portion. The light source is disposed to face to an end face of the light guiding portion in an extending direction of the light guiding portion, the end face projecting more than the light emission portion. An end face of the light guiding portion has reflecting cuts arranged in the extending direction.

Illumination device

A vehicle lamp includes a plurality of light sources and a light guide plate configured to guide light from the plurality of light sources, the light guide plate has a light diffuser configured to diffuse the light, the light diffuser has a plurality of hole sections, the hole section passes through the light guide plate in a thickness direction thereof and includes a light guide emission surface and a light guide incident surface opposite to each other in a direction in which the light entering from one end surface advances, and a plurality of concave stripe section formed in parallel to a direction crossing with the direction in which the light advances is provided at the light guide emission surface and the light guide incident surface.

Vehicle lamp

A vehicle lamp includes a plurality of light sources and a light guide plate, the plurality of light sources are disposed in parallel along one end surface of the light guide plate, the light guide plate has a light reflection section formed at a first surface of the light guide plate and configured to reflect light entered from the one end surface toward a second surface of the light guide plate, the light reflection section includes a plurality of parabolic reflection surfaces, and the parabolic reflection surfaces protrude from the first surface and have shapes curved along a direction in which the light entering from the one end surface advances and a direction crossing with the direction in which the light entering from the one end surface advances.

A vehicle lamp includes first and second lamp units separated by a gap, each having a housing and an outer lens defining a chamber, and a band-shaped light emission portion separated by the gap. The band-shaped light emission portion of the first lamp unit includes a light guiding body having an inclined end face, an incident end face proximate a light source, and a light guiding body between the inclined end face and the incident end face. A reflector, positioned behind the inclined end face, is configured to extend around and behind portions of the second housing and the second outer lens of the second lamp unit. Light from the light source is projected into the incident end face, conducted by the light guiding body to the inclined end face, and reflected by the inclined end face rearward towards the reflector which then reflects the light forward to illuminate the gap between the band-shaped light emission portions.
