Abstract: A lighting apparatus includes a first light source with a first color temperature, a second light source with a second color temperature, and a control module. The control module operates the lighting apparatus in two modes. In the first mode, the control module operates the lighting apparatus in a first linear combination of two light sources, resulting in a first operating color temperature for the lighting apparatus. In the second mode, the control module operates the lighting apparatus in a second linear combination of two light sources, resulting in a second operating color temperature. The control module is configured to alternate the operation of the lighting apparatus between the first mode and the second mode at a frequency between 35 to 45 Hz, resulting in a blended color. Additional technical features a are introduced to minimize the light output difference of the first light source and the second light source.

Abstract: A gamma stimulation apparatus comprises a rectifier, a control module, a first modulation operation switch (MOS), a second MOS, and first and second light sources. The control module operates the first light source at a first operating frequency (OF1) via the first MOS, and the second light source at a second frequency (OF2) via the second MOS. The first and second light outputs superimpose each other to form a superimposed light having a superimposed frequency equal to OF2?OF1 and between 20 Hz and 45 Hz. For every fixed period of a recalibration cycle, the control module is configured to operate only one of the two light sources or operate two light sources at a same frequency.

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.

Abstract: A self-disinfecting photocatalyst sheet includes a substrate material, a photocatalyst layer, and a primer. The photocatalyst layer comprises a primary photocatalyst and a secondary photocatalyst. The primary photocatalyst is anatase titanium dioxide and the secondary photocatalyst comprises a metallic photocatalyst. The secondary photocatalyst absorbs a visible light energy, transfers the energy to the primary photocatalyst, thus activating the primary photocatalyst as the primary disinfecting agent. The substrate material binds the photocatalyst layer by either connecting the primary photocatalyst and/or the secondary photocatalyst through two oxygen atoms of a carboxyl group (COO) comprising the primer, or by forming hydrogen bonds between the carbonyl group and a surface hydroxyl group (OH—) of the primary photocatalyst. The self-disinfecting photocatalyst sheet is activatable by a visible light and can self-disinfect against bacteria and viruses.
