Abstract: A lighting device that comprises a housing, a first visible light source, a second visible light source, an air filter, an airway, and an air circulation mechanism for each airway. The first visible light source contributes to the light output of the device, whereas the second visible light source is responsible for germicidal irradiation by activating a visible-light activatable photocatalytic coating on the air filter. The airway has an air inlet and an air outlet. The air circulation mechanism sucks an ambient air through the air inlet, forces the air through the air filter, and releases the air through the air outlet. The air filter traps airborne particles. The second visible light source is disposed adjacent to the air filter and activates a photocatalyst material in the antiviral photocatalytic coating. Airborne microbials trapped by the air filter are decomposed by the activated photocatalyst material in the antiviral photocatalytic coating.

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 entrainment enhancement device includes a housing, a first directional light source, a second directional light source, and a driver. During daytime, the driver turns on the first directional light source with a high melanopic ratio to enhance the daytime circadian entrainment of a user. During nighttime, the driver turns on the second directional light source with a low melanopic ratio to enhance the nighttime circadian entrainment of a user. A more advanced version of the present disclosure uses a light sensor, a memory module, and a computation module to calculate the necessary light output of the device by factoring the ambient light level into consideration. An even more advanced version of the present disclosure uses a distance sensor to adjust the light level of the light sources according to the distance between the device and the user.

Abstract: A lighting device that comprises a housing, two light sources, at least one airway, an air filter in each airway, and an air circulation mechanism for each airway. The air filter is coated with an antiviral photocatalytic coating. The first light source contributes to the light output of the device, whereas the second light source activates the photocatalyst material in the antiviral photocatalytic coating on the air filter.

The short leg is rotatable about the long leg. The button is movable to a blocking position to block the short leg from rotation about the long leg, and to an unblocking position to permit the rotation of the short leg about the long leg. The key-operated lock core is configured to drive the button in one direction to the blocking position and in a reverse direction to the unblocking position. The indicator is movable with respect to the key-operated lock core and the button. The indicator is movable from an original position, toward a first horizontal level that is tangent to the vertex of the arch section of the shackle, to an indicative position outside the shell.
