Abstract: A ultraviolet (UV) intensity indicator might use a UV responsive lumiphore to provide a converted, visible light level proportional to received UV light intensity for comparison to a visible brightness reference. For a desired UV intensity, the converted light should normally appear at least as bright as the reference light. For undesired UV, e.g. in a harmful wavelength range, the converted light should appear dimmer than the reference for normal operation and/or appear as bright as or brighter than the reference during excessive emission of the potentially hazardous UV emission. Alternatively, saturable lumiphores may provide different color outputs responsive to UV intensities for comparison to a multi-colored reference. Other examples contemplate use of a lumiphore to convert UV light to provide a visible light input to a visible light meter, such that an illuminance or brightness measurement by the meter gives a proportional representation of intensity of the UV light.

Abstract: A lighting fixture for powering multiple LED groups to generate a selectable color temperature. The lighting fixture provides varying amounts of power to each group of LEDs to achieve a selected color temperature. Current from a driver may be divided between the LED groups based on a selected operational state, which is selected using a switch or other configurable input. The operational states may turn the LED groups on or off or may control an amount of current received by the LED groups. In some configurations, all of the LED groups are always at least partially powered.

Abstract: Certain aspects involve a lighting fixture including multiple de-saturated color LED groups and in which the color temperature and intensity of the generated light can be selectively modified. The lighting fixture is driven by a multi-channel driver that independently controls the multiple de-saturated color LED groups. In one example, the de-saturated color LED groups are made with the same Indium gallium nitride (InGaN) LED, as to maintain all electrical/thermal characteristics. The color temperature and intensity of the lighting fixture are adjusted by managing the intensity of each of the de-saturated color LED groups according to a lookup table or a formula describing the relationship between the intensities of the de-saturated color LED groups and the color temperature and intensity of the lighting fixture. Because de-saturated color LEDs are used in the lighting fixture, dynamic dimming or “warm dim” can be achieved to replicate the effect of an incandescent lamp.
