Abstract
A light source unit of a vehicle lighting system includes: a light source to emit excitation light; a light generating unit including a luminescent layer to emit generation light by being irradiated with the excitation light and a holding member holding the luminescent layer; and a lens member to output generation light from the luminescent layer toward the front, with the light source unit mounted on the vehicle.
Claims12
A light source unit of a vehicle lighting system, the light source unit comprising:
- a light source that emits blue excitation light;
- a light generating unit that
- includes a luminescent layer to emit red generation light by being irradiated with the blue excitation light, a flexible holding member that holds the luminescent layer and a flexible sealer for sealing the luminescent layer, and
- generates the red generation light that is obtained by surface emitting of a luminescent surface of the luminescent layer;
- and
- a lens member that outputs the red generation light generated by the light generating unit toward a front, the lens member transmitting red light and absorbing list which is different from red light,
- wherein the light source is disposed under the light generating unit and the lens member in a vertical direction, and
- the flexible sealer transmits the blue excitation light and the red generation light.
A light source unit of a vehicle lighting system, the light source unit comprising:
- a light source that emits blue excitation light;
- a light generating unit that
- includes a luminescent layer to emit red generation light by being irradiated with the blue excitation light, a flexible holding member that holds the luminescent layer and a flexible sealer for sealing the luminescent layer, and
- generates the red generation light that is obtained by surface emitting of a luminescent surface of the luminescent layer;
- and
- a lens member that outputs the red generation light generated by the hot generating unit toward a front, the lens member transmitting red light and absorbing light which is different from red light, wherein
- the light generating unit includes a reflective layer that reflects the red generation light toward a front, and
- the flexible sealer transmits the blue excitation light and the red generation light.
