Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. The waveguide includes a light extraction component. The waveguide transmits light from a light source to the light extraction component by total internal reflection (TIR). The light extraction component includes one or more reversibly moveable surfaces for altering illuminance distribution patterns of the luminaire in response to one or more forces applied to the light extraction component by a force application assembly of the luminaire.

In one aspect, optic assemblies are provided comprising a collimating optic directing light along a collimation axis and light redirection elements comprising facets for redirecting a portion of the light in one or more directions away from the collimation axis.

Optic assemblies and applications thereof

Sensor housings, modules, and luminaires comprising the same are provided. The sensor housings and modules set forth herein have improved heat sinking abilities for dissipating heat from a sensor while simultaneously facilitating thermal isolation of the sensor. Briefly, a sensor housing described herein comprises a cavity for housing a sensor and a heat sink. The heat sink is configured to dissipate heat from the sensor housing and thermally isolate the sensor housing from other heat generating components, such as other portions of a luminaire.

A lighting fixture appears as a skylight and is referred to as a skylight fixture. The skylight fixture has a sky-resembling assembly and a plurality of sun-resembling assemblies. The sky-resembling assembly has a sky-resembling optical assembly and a sky-specific light source, wherein light from the sky-specific light source exits a planar interior surface of the sky-resembling light optical assembly as skylight light. The plurality of sun-resembling assemblies are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly. Each of the plurality of sun-resembling assemblies has a sun-resembling optical assembly and a sun-specific light source, wherein light from the sun-specific light source exits a planar interior surface of the sun-resembling optical assembly as sunlight light.

In view of delamination and other failure mechanisms, bonded assemblies are described herein comprising one or more reinforcement members reducing deflection of the assemblies under applied flexural loads, wherein the reinforcement members do not materially interfere with the functionality of the bonded assemblies. In one aspect, waveguide assemblies are provided. A waveguide assembly, in some embodiments, comprises a waveguide body and light extraction elements bonded to the waveguide body, wherein at least one reinforcement member is coupled to the waveguide assembly at one or more locations to reduce deflection of the waveguide assembly under an applied flexural load.

Bonded optical systems and applications thereof

According to an aspect of the present disclosure, a luminaire comprises a plurality of waveguides, a light source arranged to direct light into the plurality of waveguides, and a plurality of extraction feature patterns. The luminaire contemplated by the present disclosure is arranged with the plurality of waveguides are aligned such that an extraction feature pattern extracts light out of a first waveguide of the plurality of waveguides and a second extraction feature pattern extracts light out of a second waveguide of the plurality of waveguides. Further, in accordance with this aspect, the light extracted out of the first waveguide is directed through the second waveguide to develop an appearance of depth.

A compact and efficient LED array lighting component comprising a circuit board with an array of LED chips mounted on it and electrically interconnected. A plurality of primary lenses is included, each of which is formed directly over each LED chip and/or a sub-group of the LED chips. A heat sink is included with the circuit board mounted to the heat sink so that heat from the LED chips spreads into the heat sink. In some embodiments the circuit board can be thermally conductive and electrically insulating. Method of forming an LED component are also disclosed utilizing chip-on-board mounting techniques for mounting the LED chips on the circuit board, and molding of the primary lenses directly over the LED chips individually or in sub-groups of LED chips.

According to one example aspect, a device for venting a luminaire compartment comprises a luminaire compartment disposed between first and second luminaire components and one or more luminaire gaskets maintaining a weather-proof seal about the luminaire compartment. The device further comprises one or more venting tubes traversing the one or more luminaire gaskets such that the one or more venting tubes extend into the luminaire compartment and the one or more venting tubes equalize one or more environmental parameters of the luminaire compartment with one or more environmental parameters of the ambient environment.

Emitter packages are disclosed that can include an insulating layer covering the emitter, such as between the emitter's primary emission surface and a lens or encapsulant. The packages can comprise a submount with an emitter flip-chip mounted such that the diode region is between the emitter's non-insulating and/or conductive substrate and the submount. The submount can then be covered with a thin insulating layer. The same or another insulating layer can cover other electrically active surfaces on the submount. By insulating the electrically active surfaces of the emitter and, in some embodiments, other electrically active surfaces, the package can meet UL8750 class 4 enclosure standards even if it does not meet the lens adhesion criteria. This can enable the use of cheaper and/or more optically efficient materials at the fixture level, since the package itself meets class 4 standards.
