摘要： A light tube apparatus includes a tubular housing, a first light source, a second light source, a driver and a controller. The tubular housing having a first light passing window and a second light passing window. The first light source is for emitting a white light from the first light passing window in an illuminating mode. The second light source is for emitting an ultraviolet light from the second light passing window in a sanitizing mode. The driver is for converting an external power source to a first driving current to the first light source and a second driving current to the second light source. The controller is for determining when to enter the sanitizing mode or the illuminating mode based on a stored criterion.

摘要： A light bulb includes a bulb shell, a light source, a driver, a head housing and a bottom switch. The light source is enclosed by the bulb shell for emitting a light through the bulb shell. The driver converts an external power to a driving current supplied to the light source. The head housing has an Edison cap. The head housing is coupled to the bulb shell. The driver is enclosed by the head housing. The Edison cap is plugged to an Edison socket for receiving the external power source. The bottom switch is disposed on the bottom of the Edison cap for changing a setting of the driver.

摘要： A lighting apparatus includes a light source plate, a surface rim and a light passing cover. The light source plate is mounted with a light source. The light source plate is placed upon the support plate. The surface rim has an inner wall and an exterior wall. The inner wall has a top part and a bottom part. A bottom diameter of the bottom part is smaller than a top diameter of the top part. The light source is placed closer to the bottom part of the inner wall and surrounded by the bottom part of the inner wall. The light passing cover is attached to the top part of the inner wall. An exterior edge of the exterior wall is attached to a peripheral edge of the support plate.

摘要： A light bulb apparatus includes a bulb shell, a flexible filament, a driver circuit and a bulb cap. The bulb shell has a top area and a lateral area. The flexible filament has a top portion and a lateral portion. The flexible filament is twisted as a spiral shape. More than 50% of a first light emitted from the lateral portion passes through the lateral area. More than 50% of a second light emitted from the top portion passes through the top area of the bulb shell. The driver circuit converts an external power source to a driving current supplied to the flexible filament. The bulb cap encloses the driver circuit for connecting to the external power source. The top area of the bulb shell and the bulb cap are located at two opposite sides of the lateral area of the bulb shell.

摘要： A light box includes a LED light tube including a first cap, a second cap, a first light body and a second light body. The first light body has a first main light emitting direction and the second light body has a second main light emitting direction. The first cap and the second cap each have two pins. The first cap and the second cap is fixed at two ends of the first light body providing a power to the first light body and the second light body. The angle between first main light emitting direction and the second main light emitting direction is adjustable by adjusting a relative position between the first light body and the second light body.

摘要： A lighting apparatus includes a light source plate, a LED module, a first wire, a second wire and a terminal housing. The light source plate has a first connector and a second connector. The LED module is mounted on a first side of the light source plate to be electrically connected to the first connector and the second connector. The first wire passes through a first passage on the light source plate from a second side of the light source plate to the first side of the light source plate to engage the first connector. The second wire passes through a second passage of the light source plate from the second side of the light source plate to the first side of the light source plate to engage the second connector. The terminal housing encloses the first wire and the second wire.

摘要： The back plate has four lateral walls and a bottom plate. A back side of the bottom plate includes multiple sets of folding hooks. Each set corresponds a different installation platform. One of the multiple sets of folding hooks is folded to be used for hooking to a corresponding installation platform. The light source module has multiple LED modules disposed on the bottom plate. Each LED module has a LED device and a lens. The lens diffuses a light of the LED device to be evenly emitted from the lens and broadening an output angle of the light via the lens. The diffusion plate with a peripheral edge is fixed to the four lateral walls of the back plate. The driver cover is attached to an external side of one of the four walls of the back plate. The driver cover defines a container cavity for concealing the driver module.
