Abstract
The present disclosure relates to a device that includes a blue-emitting light emitting diode (LED) capable of emitting blue light at a first intensity and a non-blue-emitting LED capable of emitting light having a color other than blue, at a second intensity, where the first intensity is variable.
Claims20
A device comprising:
- a blue-emitting light emitting diode (LED) capable of emitting blue light at a first intensity;
- and
- a non-blue-emitting LED capable of emitting light having a color other than blue, at a second intensity, wherein:
- the first intensity is variable.
1 more element
A method comprising:
- mixing a blue light with a second light that is in the visible spectrum and not blue;
- and
- varying an intensity of the blue light, wherein:
- the mixing and the varying result in a light having a property comprising at least one of a color temperature, a color-rendering index, a wavelength distribution, or a total intensity, and
- the property meets at least one of a tolerance level of local wildlife or a value set by a local regulation.
