Said lighting device is made up of lighting elements (L1, L2, . . . , L20) arranged on a mounting board (PS1, PS2, etc.). The one or more boards are arranged so as to supply light with a predetermined coverage. The boards comprise a plugging system (C1, C2, C3, P1, P2, P3) for connecting said lighting elements. The mounting of such a device using a threaded rod 7 makes it possible to obtain easy maintenance of the device of the invention. This device can easily be used to form striplights. Use: Lighting of car parks, meeting rooms.

A LED based lighting apparatus is disclosed. The light engine used in the lighting apparatus may use printed circuit board and have a plurality of LED groups that are independently controllable by a control unit. The power supply input and return paths connected to each LED group may be implemented on different layers to allow a compact footprint that may be used with traditional fluorescent encasements with relatively little modification. The LEDs may comprise a subset of LEDs having a first color and a subset of LEDs having a second color different from said first color intertwined on the light engine.

A lamp-equipped tent shelf, comprising a shelf, an LED lighting assembly, and a plurality of hooks is provided. The hooks are connected to the shelf. The LED lighting assembly is disposed on the shelf. The LED assembly comprises a power source, an LED light source and a switch. The LED light source is connected to the power source and the switch control the LED light source to turn on and off. The tent shelf can be hung directly to the tent frame and serves as an illumination source.
