Abstract
A lighting arrangement for providing visible light and radiation in another spectrum that is medically beneficial is provided. The lighting arrangement comprises a light source adapted to emit visible light; a radiation source adapted to emit radiation in a predetermined spectrum, and a driver circuit adapted to provide a first driving current that is pulsed and has a duty cycle of not greater than 20%. The predetermined spectrum is preferably in the range 760-1400 nm. The lighting arrangement is adapted to provide the first driving current to the radiation source but not the light source. Corresponding method and products employing such lighting arrangement are also provided.
Claims25
A lighting arrangement for general lighting, comprising:
- a light source capable of emitting visible light suitable for general lighting, the visible light being white light;
- a radiation source capable of emitting radiation in a predetermined spectrum, wherein the predetermined spectrum is in a range 760-1400 nm;
- and
- a driver circuit capable of providing a first driving current that is pulsed;
- wherein the lighting arrangement is configured to provide the first driving current to the radiation source but not the light source;
- and
- wherein, in use, the light source is configured to emit at least 250 lumens,
- wherein a peak emission power of the radiation source receiving the pulsed first driving current enables a power density of 0.4-50 mW/cm2, measured at a common average distance of between 0.2 and 5 m from the radiation source.
