摘要:
Materials and optical components formed thereof that are suitable for use in a lighting apparatus to impart a color filtering effect to visible light. At least a portion of such an optical component is formed of a composite material comprising a polymeric matrix material and an inorganic particulate material that contributes a color filtering effect to visible light passing through the composite material, and the particulate material comprises a neodymium compound containing Nd3+ ions.
摘要:
A lighting system and method electrically control optics of light generated by a light source. The light source generates a light defined by a light distribution. An electro-active optical component changes the light distribution responsive to a change in an electric potential applied across the electro-active optical component by an electronic control system.
摘要:
The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module configured to generate a visible light such as white light, and at least one component such as an optical component comprising multiple (two or more) compounds, each containing neodymium (Nd) and at least one compound including fluorine (F) for imparting a desired color filtering effect to provide a desired light spectrum, where a color of the desired light spectrum in a color space is determined by relative amounts of the two or more compounds in the at least one component.
摘要:
Provided is an LED retrofit lamp interfacing with a high intensity discharge (HID) ballast that includes a lighting source having a plurality of light emitting diodes (LEDs), one or more heat sink components dissipating heat generated by the LEDs, and an LED driver configured to operate the LEDs.
