Disclosed is a LiDAR window integrated optical filter that includes a window of a polymer material for absorbing a visible light band and transmitting a near-infrared band; and an upper reflective layer and a lower reflective layer formed on the upper surface and the lower surface of the window. The upper reflective layer and the lower reflective layer may be formed in a thin film including titanium dioxide (TiO) and silicon dioxide (SiO).

LiDAR window integrated optical filter

A backlight unit for blind spot warning lighting includes a printed circuit board (PCB) mounted with a light-emitting diode (LED), a bottom case having the PCB embedded on a lower portion thereof, and having an opened front surface, and a top case comprising a front plate covering a the front surface of the bottom case, and a guide protrusion formed to protrude backward from a rear surface of the front plate to guide the light from the LED to the front plate, and an object of the present disclosure is to provide a backlight unit, which can uniformly emit light while unifying the number of reflection and diffusion layers, and be advantageous for applying a hot wire, thereby improving visibility.
