Abstract

Bioactive display systems for displaying digital content. The display systems have one or more LED-based lighting channels adapted to generate one or more of a long red near infrared (LRNE) red light, a circadian-inducing blue light output in first operational mode and a less-circadian-inducing blue light output in a second operational mode. The bioactive lighting can have a first circadian-stimulating energy characteristic related to the associated first spectral power distributions of light generated in the first operational mode, and the non-circadian-inducing blue light can have a second circadian-stimulating energy characteristic related to the associated second spectral power distribution of light generated in the second operational mode. Disclosure methods of generating digital display content with the display systems described herein. The methods can generate a circadian-inducing blue light output in first operational mode and one of a LRNE output and a less-circadian-inducing blue light output in a second operational mode.

Claims (13)

1 . A display system comprising:

one or more LED-based lighting channels adapted to emit light in different modes,

a first mode in which a relatively high circadian-stimulating energy (CSE) light is emitted, output

a second mode in which a relatively low CSE light is emitted,

a third mode in which long red near infrared energy (LRNE) light is emitted,

a controller configured to control said one or more LED-based lighting channels in any combination of said first, second, and third modes,

wherein in said third mode, said LRNE light is pulsed.

2 . The display of claim 1 , wherein said controller is configured to pulse said LRNE light at certain frequency.

3 . The display of claim 2 , wherein said certain frequency comprises micro-pulses of less than a tenth of a second.

4 . The display of claim 3 , wherein said micro-pulses have a duration of less than 100 ms, with a frequency between 10 Hz and 0.5 mHz.

5 . The display of claim 1 , wherein said controller is configured to pulse said relatively high CSE at certain frequency.

6 . The display of claim 5 , wherein said certain frequency comprises micro-pulses of less than a tenth of a second.

7 . The display of claim 6 , wherein said micro-pulses have a duration of less than 100 ms, with a frequency between 10 Hz and 0.5 mHz.
