Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Silicone optics

Certain examples involve a circadian effect light fixture. The circadian effect light fixture includes a controller to receive a modifying factor based on a circadian impact profile. The modifying factor includes an indication of an intensity value, a correlated color temperature value, and a color value over a range of time. The circadian effect light fixture also includes a first lighting element controlled by the controller to produce a first light output having a first intensity, a first correlated color temperature, and a first color value. Further, the circadian effect light fixture includes a second lighting element controlled by the controller to produce a second light output having a second intensity, a second correlated color temperature, and a second color value. A combined light output of the first lighting element and the second lighting element tracks the modifying factor over the range of time.

Systems and methods to provide circadian impact

Certain examples involve controlling a circadian impact of a lighting system. For instance, a lighting system includes a first lighting fixture. The first lighting fixture includes at least one lighting element to illuminate a first space and a first controller to control a first light output of the at least one lighting element. Additionally, the lighting system includes a first background circadian system that provides a first modifying factor to the first controller of the first lighting fixture. The first modifying factor is associated with a first circadian impact profile that specifies a first circadian impact level in the first space. Further, the first controller of the first lighting fixture controls the first light output based on the first modifying factor.

A light fixture includes a flexible shroud, an outer housing, and a light source within a light engine. The light engine couples within the outer housing so as to define a gap between the light engine and an inner perimeter of the outer housing. The flexible shroud forms at least first and second edge portions. The light engine couples with the first edge portion, and the inner perimeter of the outer housing couples with the second edge portion, so that the flexible shroud covers at least part of the gap. A shroud for a light fixture may include a flexible shroud that defines one or more edges. The shroud may include one or more coupling features along the one or more edges. The flexible shroud may form a thickness variation at the coupling feature, to engage a corresponding coupling feature of a light fixture.

Optics over a light source, such as, but not limited to, an LED on a circuit board. The optic does not entirely encapsulate the LED but rather includes an inner surface such that an air gap exists between the optic and the LED. The optic may include a lens and may conform to the shape of the circuit board.

Optic for a light source

A lighting fixture may provide a proximal lighting effect and a distal lighting effect. In some cases, the lighting fixture may include a multi-channel driver and multiple groups of LEDs. Based on an adjustable input level, the driver may provide current to subgroups of the LEDs, arranged at various areas of the lighting fixture. Responsive to the level of the input, the driver may provide current to various LED subgroups at the various areas, such that a particular proximal effect is provided at a particular area of the lighting fixture based on the particular value of the input level. In addition, the distal lighting effect may have a stable value across the adjustments to the input level, and the corresponding adjustments to the proximal effects. The distal effect may be perceivable at a location remote from the lighting fixture, such as a work surface.

Lighting fixture configured to provide multiple lighting effects

A luminaire may include a plurality of different light engines. Light engines having different light distributions can be included in a single luminaire and a subset of the light engines selectively driven to dynamically change the light distribution of the luminaire. In this way, a single luminaire is capable of illuminating an area with a variety of different light distributions.

Adaptive optical distribution system

A system allows a light fixture to have a wider range of color temperatures (CCT) while limiting the warmest temperature reached at full intensity. The CCT of the light output may be controlled independently of intensity across a certain range of CCT and dependent on intensity across another range. In an implementation, both intensity and CCT may be adjusted from a single handle, where the interface positions may be divided into multiple zones. In another implementation, intensity may be adjusted from a first handle, while CCT may be adjusted from a second handle. The CCT of the light output may be limited to cooler levels when the intensity is higher, and/or the intensity of the light may be limited to lower levels when the CCT is warmer.

Method for controlling a tunable white fixture using a single handle

A processing device can digitally control lighting fixtures by receiving a request to generate light at a correlated color temperature ('CCT') level in an environment. The environment can include a first lighting fixture having a first range of generatable CCT values and a second lighting fixture having a second range of generatable CCT values. The processing device can determine a first CCT value based on the request and the first range. The processing device can further determine a second CCT value based on the first CCT value and the second range. The processing device can further transmit a first digital signal to the first lighting fixture to cause the first lighting fixture to generate light at the first CCT value. The processing device can further transmit a second digital signal to the second lighting fixture to cause the second lighting fixture to generate light at the second CCT value.
