  • Patent number: 10018341
    Abstract: A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board assembly (PCBA) containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The lens may include a first pair of opposing surfaces forming a first focus and a second pair of opposing surfaces forming a second focus. The first and second foci may cause light to be subtended into one or more of collimated light focused light, diffused light, and shifted light. The carrier may include an obstruction extending toward the PCBA.

  • Patent number: 9964278
    Abstract: A reflecting surface of a reflector has a structure where a plurality of reflecting elements are arranged in rows in an up-and-down direction, and the reflecting elements are arranged as a plurality of sets in a left-and-right direction. The surface of each reflecting element is composed of a curved surface having a horizontal section curvature larger than a vertical section curvature. Thus, a horizontally long light distribution pattern may be easily formed by light reflecting from each reflecting element. Each reflecting element is connected to each of four reflecting elements which are adjacent thereto in the left-and-right direction and are shifted therefrom in the up-and-down direction, through a boundary line extending from a vertical plane in an inclined direction in the left-and-right direction. Thus, the horizontally long light distribution pattern formed by the light reflecting from each reflecting element becomes a bright light distribution pattern having four chipped corners.

  • Patent number: 9964683
    Abstract: The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.
