Abstract
Systems and methods for pulsing high intensity narrow spectrum light are provided. In one example embodiment, a lighting system includes can include one or more high intensity narrow spectrum light sources configured to emit high intensity narrow spectrum light. The lighting system can further include a power circuit configured to provide power to the one or more high intensity narrow spectrum light sources and a pulsing circuit configured to control delivery of power to the one or more high intensity narrow spectrum light sources so as to pulse the emission of high intensity narrow spectrum light from the one or more high intensity narrow spectrum light sources.
Claims20
A lighting system, comprising:
- one or more high intensity narrow spectrum (HINS) light sources configured to emit HINS light;
- one or more non-HINS light sources configured to emit non-HINS light in the visible spectrum;
- a power circuit configured to provide power to both the one or more HINS light sources and the non-HINS light sources;
- a control circuit configured to control delivery of power to the one or more HINS light sources and the one or more non-HINS light sources to pulse the emission of light according to a pulsing scheme the pulsing scheme comprising a first pulse and a second pulse, the first pulse associated with a first duration and a first intensity and the second pulse associated with a second duration and a second intensity,
- wherein the first duration and the second duration are different durations,
- wherein both the first pulse and the second pulse of the pulsing scheme are applied to one HINS light selected from the one or more HINS lights, and selectively cause the one HINS light selected from the one or more HINS lights to emit HINS light according to the pulsing scheme, and
- wherein the one or more non-HINS lights emits non-HINS light in the visible spectrum independently of the one or more HINS lights.
A method of controlling one or more high intensity narrow spectrum (HINS) lighting sources and one or more non-HINS lighting sources, the method comprising:
- providing, by one or more power circuits a multichannel driver circuit having a first channel and a second channel, power to one or more of the HINS lighting sources and the non-HINS lighting sources;
- obtaining, by one or more control circuits, data indicative of a pulsing scheme, the pulsing scheme comprising a first pulse and a second pulse, the first pulse associated with a first duration and a first intensity and the second pulse associated with a second duration and a second intensity, wherein the first duration and the second duration are different durations;
- controlling, by the one or more control circuits, power provided by the one or more power circuits to the one or more HINS lighting sources and the non-HINS lighting sources based at least in part on the data indicative of the pulsing scheme so as to pulse the emission of HINS light from the one or more HINS lighting sources,
- wherein both the first pulse and the second pulse of the pulsing scheme are applied to one HINS light selected from the one or more HINS lights, and configured to selectively cause the one HINS light selected from the one or more HINS lights to be emitting HINS light for at least part of a period during which non-HINS light in the visible spectrum is being emitted and not emitting HINS light for at least part of the period during which non-HINS light in the visible spectrum is being emitted.
