Abstract
A lighting apparatus comprises a controller and three lights sources each with a different color temperature. The controller turns on the second light source and the third light source alternately at a strobing frequency between 30 Hz and 65 Hz, resulting in a strobing light (out of the second light source and the third light source) with a combined color temperature approximating the color temperature of the first light source. Alternatively, the lighting apparatus includes a controller and two light sources. The first light source and the second light source operate at different frequencies, resulting in a superimposed light with an operating frequency equal to the difference of these two frequencies. Alternatively, the lighting apparatus turns off one of the two light sources periodically for a short period of time to induce the brain of a subject to better recognize the frequency of the superimposed light.
