Abstract
A vehicle interior lighting system includes: a designed cover 10 attached to a ceiling wall in an inside of a vehicle compartment; and a light source unit 20 arranged in the rear of the designed cover. In this system, a light beam emitted from an emission port 25 of the light source unit illuminates the inside of the vehicle compartment through two irradiation holes 15 for spot illumination, which are provided in the designed cover. A light guide 50 is arranged between the emission port 25 of the light source unit and the two irradiation holes 15 of the designed cover. The light guide 50 is configured to divide the light beam emitted from the light source unit into two directions, and to guide the thus-divided light beams to the respective irradiation holes.
Claims7
A vehicle interior lighting system, comprising:
- a designed cover attached to a ceiling wall in an inside of a vehicle compartment;
- and
- a light source unit arranged in a rear of the designed cover, wherein
- a light beam emitted from an emission port of the light source unit illuminates the inside of the vehicle compartment through a plurality of illuminators provided in the designed cover;
- and
- a light guide is arranged between the emission port of the light source unit and the plurality of illuminators in the designed cover, the light guide being configured to divide the light beam emitted from the emission port of the light source unit into a plurality of light beams which travel in different directions and thereby to guide the light beams thus divided to the respective plurality of illuminators.
A vehicle interior lighting system, comprising:
- a designed cover attached to a ceiling wall in an inside of a vehicle compartment;
- and
- a light source unit arranged in a rear of the designed cover, wherein
- a light beam emitted from an emission port of the light source unit illuminates the inside of the vehicle compartment through a single illuminator provided in the designed cover;
- and
- a prism-shaped light guide is arranged between the emission port of the light source unit and the single illuminator in the designed cover, the light guide being configured to divide the light beam from the emission port of the light source unit into a plurality of light beams which travel in different directions, and thus to emit the light beams thus divided in the different directions through the single illuminator.
