A LED light apparatus is designed to being connected to an external power source via a host connector. The light source has a LED light source, a light housing, a driver circuit and a plastic device connector housing. The plastic device connector housing has a receiver socket for detachably receiving a corresponding plastic plug of the host connector. When the plastic plug of the host connector is inserted into the receiver socket, metal terminals of the host connector engage elongate flat front ends fixed to the plastic device connector housing.

A lighting unit comprises a mount for rotating a plasma light source within a cylinder of metal gauze that provides a primary Faraday cage for shielding against radio-frequency radiation from the light source. The shielding is extended using a parabolic reflector for the emitted light in combination with a gauze to establish a secondary Faraday shield enclosing the primary cage. The gauze covers a ring that is sealed between the rim of the front open-mouth of the reflector and a slide-in cassette of the lighting unit, and can be of a metallic honeycomb configuration enhancing the operation and light output from the unit.

A plant illumination optical device includes two LED lamp bodies. Each of the LED lamp bodies includes a reflector and an LED lamp located at an inner side of the reflector, and an angle between the central light rays of the two LED lamp bodies is adjustable. A plant cultivation device contains the plant illumination optical device. The plant illumination optical device and the plant cultivation device can reflect the light beyond the planting area to the planting area and can supplement the illumination on both sides of the illumination centerline, thereby avoiding light waste, improving energy efficiency, improving the illumination uniformity in the planting area, and improving planting quality of the planting area.

An edge-lit plate-form lamp includes a plate-form bottom casing, a plate-form top casing, an illuminating component and a plug. The plate-form bottom casing has a cavity disposed within. The plate-form top casing detachably engages with the bottom casing. The plate-form top casing includes a window. The illuminating component is disposed within the cavity. The window allows light emission from the illuminating component within an emission area defined by the window. The plug extends across the plate-form bottom casing. Also, the plug is electrically coupled to the illuminating component. In addition, the plug relays power to the illuminating component while being electrically coupled to an external power source.

Light fixtures often have bright spots caused by the light sources that can be unpleasant or uncomfortable to look at. A light system is provided that diffuses the light. The light system includes an exterior body defining a void therein and an internal structure positioned within the void. The internal structure comprises at least a web and a flange extending from the web, and one or more lights positioned along the length of the web. The internal structure supports the exterior body.
