Abstract: A therapeutic lighting apparatus includes two white light sources each with a different color temperature and a controller. The controller operates the lighting apparatus in either a color temperature fusion mode or a color temperature flickering mode or both simultaneously such that the color temperature flickering mode can be used for treating a patient with Alzheimer's disease. The lighting apparatus can be enhanced with a green light source for supporting a green light mode for treating migraine headache. Similarly, the lighting apparatus can be enhanced with a red light source for supporting a red light mode for tissue repairing. Alternatively, the lighting apparatus can be enhanced with a near-infrared (IR) radiation source for supporting a near-IR mode for lowering the heartbeat, uplifting the mood, and improving the immunization system of a subject.

Abstract: A self-disinfecting photocatalyst sheet includes a substrate material and a photocatalyst layer with a primary photocatalyst and a secondary photocatalyst. The primary photocatalyst is a metal oxide photocatalyst, whereas the secondary photocatalyst is a metallic photocatalyst. The substrate material binds the photocatalyst layer by either connecting a metal ion of the primary photocatalyst and/or the secondary photocatalyst through two oxygen atoms of a carboxyl group (COO), or by forming hydrogen bonds between a 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.

Abstract: A lighting device comprises a light head, two light sources, and a safeguard mechanism. The light head houses the two light sources. The first light source emits predominantly ultraviolet (UV) light ( 400 nm) for general lighting. The lighting device may operate in two modes. The first operation mode is the general lighting mode, where the second light source is on for providing general lighting. The second operation mode is the germicidal lighting mode, where the first light source is on for providing germicidal lighting. The safeguard mechanism prevents the first light source in the germicidal lighting mode from turning on and causing accidental human exposure to the UV light from the first light source.

Abstract: An anti-bacterial lighting device includes a translucent housing, a first light source, a second light source, an air-inflow port, and an air circulation mechanism. The translucent housing is air-permeable and coated with an anti-bacterial photocatalyst on its surface. The first light source is a visible light source emitting a visible light with a spectral power distribution (SPD)>95% in a visible light wavelength range (>400 nm). The second light source is a far-UVC light source emitting a non-visible light with an SPD>90% in a 200 nm˜230 nm wavelength range. The lights of the first light source and the second light source shine through the translucent housing and activates the anti-bacterial photocatalyst on the housing. The air circulation mechanism sucks an ambient air into the housing through the air-inflow port and forces the air out through the air-permeable housing.

Abstract: A circadian lighting apparatus includes a housing, two light sources, and a control logic. The first light source is a blue-enriched light source for stimulating human to a high circadian mode. The second light source is a blue-depleted light source for calming down human to a low circadian mode. The criteria of a good circadian lighting apparatus are identified. When coated with an anti-bacterial photocatalytic coating on the exterior, the circadian lighting apparatus becomes a disinfecting equipment that can kill the airborne bacteria and viruses that make contact to its anti-bacterial photocatalytic coated surface.

Abstract: A photocatalytic device includes one transparent or translucent carrier and at least one photocatalytic film. The carrier is in the form of a sheet with two opposite surface. At least one of the two surfaces of the carrier is at least partially coated with the photocatalytic film. The photocatalytic film is photocatalytic activated by visible light with wavelength>400 nm for providing the antibacterial functionality. In some situation, only the outer surface of the carrier is coated with the photocatalytic film. In other situation, only the inner surface of the carrier is coated with the photocatalytic film. There are situations where both surfaces of the carrier are coated with the photocatalytic film. The carrier has an attaching mechanism for attaching the carrier to the external solid object, and the carrier is attachable to and detachable from the external solid object hands of a user without using a tool.

Abstract: An omnidirectional lighting device may include a driver base and a plurality of elongated light sources. The driver base may include a driver configured to convert an external alternating-current (AC) power to a direct-current (DC) power and supply the DC power to the plurality of elongated light sources. Each of the plurality of elongated light sources protrudes independently out of a second side of the driver base, and each source is enclosed with a cylindrical lens. The plurality of the cylindrical lenses are aligned in parallel and of the same length. An aggregate lighting angle of the plurality of elongated light source may be 360 degrees.

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 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.
