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： A lighting apparatus includes a light source, a rectifier circuit, a DC-DC converter, an adjustment circuit and a controller. The rectifier circuit converts an AC power to a raw direct current. The adjustment circuit provides an adjustment signal corresponding a light intensity setting of the light source. The controller is coupled to the DC-DC converter and the adjustment circuit. The controller receives the adjustment signal for generating a first PWM signal. The DC-DC converter receives the first PWM signal. The DC-DC converter converts the raw direct current to an output current according to a first duty ratio of the first PWM signal. The output current is supplied to the light source corresponding to the light intensity setting.

摘要： A light bulb apparatus includes a cap connector, a light source, a heat sink module, a bulb shell and a reflective layer. The cap connector is used for connecting to an external power source. The bulb shell has a bottom part and a neck part. The reflective layer is disposed at the bottom part of the bulb shell for guiding a first light emitted from the LED module on the reflective layer to escape from the neck part of the bulb shell.

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.

摘要： A lighting apparatus includes a LED strip having an elongated substrate and multiple LED modules. A light passing cover enclosing the LED strip. The light passing cover have an extending linear surface with a main portion and a transition portion. A first cap and a second cap connect to the light passing cover. The first cap has a first connecting surface, a first contacting surface, and a first side surface. The second cap has a second connecting surface, a second contacting surface, and a second side surface. The first connecting surface and the second connecting surface provide a bridge connecting to the light passing cover. The first contacting surface and the second contacting surface have a transmission between an inner area and an external area of the light passing cover. The first side surface and the second side surface support a structure of the light passing cover.
