  • Patent number: 11357173
    Abstract: A method and apparatus for a horticultural light that projects either a substantially uniform target illuminance onto a flat surface or an increasing target illuminance onto a flat surface. The horticultural light uses a refractor to receive the raw light distribution from one or more LEDs and then distributes an optically varied distribution having a minimized intensity at centerbeam with an increasing beam intensity as the beam width increases. The horticultural light utilizes both ultraviolet (UV) LEDs and non-UV LEDs arranged as an array to produce the optically varied distribution. A lens array is disposed in relation to the LED array and is comprised of UV compatible lenses and non-UV compatible lenses. A device may be disposed in relation to the UV compatible lenses to disallow incidence of UV radiation onto non-UV compatible lenses.

    Abstract: A display apparatus including a light emitting body to improve external appearance thereof. The light emitting body is disposed inside a bezel to emit light. The bezel has a reflective surface to reflect light emitted from the light emitting body in front of the display apparatus. The bezel also has a light interruption groove to prevent light emitted from the light emitting body from affecting an image formed on the display module. The light emitting body is operatively connected to a user interface unit. A user manipulates a manipulation panel or a remote control to set an operation mode of the light emitting body from a menu item on an on screen display, and the light emitting body emits light in various forms based on the set mode.

    Abstract: A light guide (201) including a transparent element is presented. The transparent element includes an optical diverter section (204) including one or more reflective surfaces (205) forming walls of a notch (206) extending into the diverter section, where the reflective surfaces provide total reflections for directing light into directions lateral with respect to an arrival direction of the light. The transparent element includes an optical channel section (208) for receiving the light from a light source and for directing the light to the optical diverter section. The optical channel section includes a side surface (209) shaped to provide total reflections for directing light to the optical diverter section. The optical channel section makes it possible to place the light source a distance apart from the optical diverter section and also to prevent or at least to reduce direct propagation of light from the light source to the lateral directions.
