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 lighting fixture can achieve uniform projection of light while being capable of providing improved luxurious sense of projected light. The vehicle lighting fixture can include a housing, an outer lens configured to cover an opening of the housing to define a lighting chamber; and a light source and a light guiding lens located in the lighting chamber. The light guiding lens is configured so as to receive light from the light source and guide the light to a light exiting surface thereof for light projection. The light guiding lens has a functional surface which is opposite to the light exiting surface and can include a plurality of flute cuts configured to diffuse light and a plurality of prism cuts configured to reflect light. The plurality of prism cuts are arranged at random on the functional surface.

Vehicle lighting fixture

A vehicle lighting unit can distribute light in a wider area than the conventional lighting unit without increasing the number of parts. The vehicle lighting unit can include: a light source; a light guiding member configured to have a side portion to receive light from the light source from the side portion and guide the light, and have an inclined face formed obliquely rearward in a light guiding path of the light; and a reflection face inclined forward and disposed to face to the inclined face with a gap between the reflection face and the inclined face of the light guiding member.

Vehicle lighting unit

A lighting fixture projects light sideward and has no restriction in design. The lighting fixture can include an LED; a primary lens disposed in an optical axis of the LED, the primary lens being configured to form a main light distribution; an auxiliary lens disposed on an outer peripheral side of the primary lens around the optical axis of the LED; and a reflecting portion configured to reflect part of light emitted from the LED to substantially an entire area of the auxiliary lens on an inner peripheral surface side thereof. The reflecting portion can be formed integrally with the primary lens and include an incident surface on which part of light emitted from the LED can be incident, a reflecting surface configured to reflect light having entered through the incident surface, and a light-exiting surface configured to allow the light reflected by the reflecting surface to exit.
