20230332762 · 2023-10-19 ·

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

Lighting device having a vivid and dulling light source with controlled duty cycling thereof

A lighting device is disclosed operating a vivid source having a first duty cycle and a dulling source with second duty cycle. The vivid source and the dulling source operate at alternating time intervals where the intensity of one wavelength segment or block is emphasized in the vivid source and absent or de-emphasized in the dulling source. The operation provides the user with an emphasis on objects that reflect or absorb the emphasized wavelength segment.
