摘要： Systems for apparatuses formed of light emitting devices. Solutions for controlling the off-state appearance of lighting system designs is disclosed. Thermochromic materials are selected in accordance with a desired off-state of an LED device. The thermochromic materials are applied to a structure that is in a light path of light emitted by the LED device. In the off-state the LED device produces a desired off-state colored appearance. When the LED device is in the on-state, the thermochromic materials heat up and become more and more transparent. The light emitted from the device in its on-state does not suffer from color shifting due to the presence of the thermochromic materials. Furthermore, light emitted from the LED device in its on-state does not suffer from attenuation due to the presence of the thermochromic materials. Techniques to select and position thermochromic materials in or around LED apparatuses are presented.

摘要： A light fixture includes a housing defining a recessed cavity. The housing has a top, a first side, and a second side each extending at an angle from a first end of the housing to a second end of the housing, the first end being substantially orthogonal relative to a first plane. One or more lamp units are positioned in the housing to emit light therefrom, wherein the emitted light is prevented from leaving the housing in a direction parallel to the first plane.

摘要： A system can comprise tabs and notches or a twist-and-lock mount for detachably mounting components adjacent a light emitting diode that is utilized for illumination, for example in a luminaire. Representative mounted components can include protective covers and optics for managing light emitted by the light emitting diode. The tabs and notches can be located rear of an aperture in a recessed lighting fixture or in a cover of a luminaire, for example. That cover, or another cover that may not utilize a releasable mount, can extend circumferentially about a periphery of a light emitting diode to cover and protect wiring for the light emitting diode and to hide the wiring from view by people occupying an illuminated space.
