A display for emitting display light comprising: (a) a light source for emitting a source light; and (b) a filter positioned in the path of said source light, said filter comprising at least short, medium and long filters, wherein said short filter is configured to transmit short-primary light from said source light, said short-primary light comprising a violet portion having wavelengths from 400 to 440 nm and at least a second portion having wavelengths above 440 nm such that said short-primary light is perceptually blue, said short-primary light having a short-primary SPD having a short-primary power between 380-780 nm and a blue power between 440-500 nm, wherein said blue power is less than 5% of said short-primary power.

Low blue light displays

In one embodiment, a method comprising: (a) receiving a set of physiological data associated with at least one health condition of an animal subject; (b) receiving a set of environmental data associated with one or more environment conditions to which the subject is or has been exposed; (c) determining a set of operating parameters for at least one environmental device based at least partially on at least a portion of the set of physiological data and at least a portion of the set of environmental data; and (d) transmitting the set of operating parameters to the at least one environmental device to at least partially control at least one controlled environmental condition to which the subject is exposed to thereby at partially control the at least one health condition.

Controlling physiological conditions by controlling environmental conditions

Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

Circadian-friendly LED light source

A light source for emitting emitted light having an SPD comprising: (a) a plurality of light emitters including at least one violet solid-state emitter; (b) at least one phosphor; wherein said light emitters and said at least one phosphor being configured such that: at least 25% of the power within the SPD is in the range 390-420 nm, and the emitted light has a chromaticity which is within a Duv distance of less than 5 points from the Planckian locus.

Bacterial light source with high quality of light

LED lamp systems having improved light quality are disclosed. The lamps emit more than 500 lm and more than 2% of the power in the spectral power distribution is emitted within a wavelength range from about 390 nm to about 430 nm.

LED lamps with improved quality of light

An LED pump light with multiple phosphors is described. LEDs emitting radiation at violet and/or ultraviolet wavelengths are used to pump phosphor materials that emit other colors. The LEDs operating in different wavelength ranges are arranged to reduce light re-absorption and improve light output efficiency.

System and method for selected pump LEDs with multiple phosphors

Circadian-friendly LED light sources

A gallium and nitrogen containing optical device has a base region and no more than three major planar side regions configured in a triangular arrangement provided from the base region.

Gallium and nitrogen containing triangular or diamond-shaped configuration for optical devices

Accessories for LED lamp systems and methods of attaching accessories to illumination sources (e.g., LED lamps) are disclosed. A beam shaping accessories mechanically affixed to the LED lamp. The lens is designed to adapt to a first fixture that is mechanically attached to the lens. Accessories are designed to have a second fixture for mating to the first fixture such that the first fixture and the second fixture are configured to produce a retaining force between the first accessory and the lens. The retaining force is a mechanical force that is accomplished by mechanical mating of mechanical fixtures, or the retaining force is a magnetic force and is accomplished by magnetic fixtures configured to have attracting magnetic forces. In some embodiments, the accessory is treated to modulate an emanated light pattern (e.g., a rectangular, or square, or oval, or circular or diffused emanated light pattern). A USB connector is also provided.
