    摘要： A laser diode includes a laser diode emitting light due to an electrical signal; a wavelength conversion plate for shifting the wavelength of the light emitted from the laser diode; a reflecting part for reflecting the light emitted from the laser diode towards the wavelength conversion plate; and a projecting part for emitting, in the forward direction, the light shifted by the wavelength conversion plate. The laser diode can provide a high-power but small-sized laser light source device, and a narrow emission angle can be achieved using the laser diode.

    摘要： A lighting device for a vehicle includes a light source device; a main lens; a reflective fluorescent body configured to reflect and convert wavelengths of incident beams; and a prism arranged between the main lens and the reflective fluorescent body. The prism is configured to: reflect beams emitted from the light source device to be incident on the reflective fluorescent body; and transmit, through the prism and to the main lens, beams reflected from the reflective fluorescent body. The prism includes: a first surface facing the reflective fluorescent body; a second surface through which beams are incident; and a third surface forming an acute angle with the first surface. The prism is configured such that the beams incident through the second surface of the prism form angles of incidence, with respect to the third surface of the prism, that are greater than a critical angle of the prism.

    摘要： Provided is a head up display for a vehicle. The head up display for the vehicle may include an imaging mechanism for emitting a linearly-polarized light in a first direction and a linearly-polarized light in a second direction orthogonal to the first direction, a first reflection mirror for reflecting a light to a windshield of the vehicle, a polarization reflection mirror spaced apart from the first reflection mirror wherein the polarization reflection mirror transmits the linearly-polarized light in the first direction and reflects the linearly-polarized light in the second direction, and a second reflection mirror spaced apart from the polarization reflection mirror wherein the second reflection mirror reflects the light transmitted through the polarization reflection mirror to the polarization reflection mirror. The imaging mechanism may include a separating partition for preventing mutual interference between the linearly-polarized light in the first direction and the linearly-polarized light in the second direction.
