A modular LED light, in particular for explosive areas, has at least one LED module and one central power supply module. At least the LED module is detachably attached to a housing module. The housing module has two arrangement planes in the vertical direction, wherein at least power supply connectors for the LED lights and connection lines to the central power supply module and to the LED module are arranged in the upper arrangement plane and the LED module and a driver device on an LED module receiving element or on the central power supply module are arranged in the lower arrangement plane. The housing module has at least one LED module receiving unit that is arranged lateral to the central power supply module and in which an LED power supply interface for supplying electrical power to the LED module in its usage position is arranged in the LED module receiving element.

The present invention relates to an ambiance lighting system that uses more than one translucent panel. The translucent panels are aligned, absent occlusions along the surface, and interconnected or inserted into a luminary wrap. A light control panel comprises one or more light-emitting diodes (LED), a power source, and selectively a GPS, audio-video interface, and a communication interface. The light control panel is orientated to illuminate and project light through the translucent panel creating an ambiance lighting effect. A box spinner, box panels, post adapter, colored lens, accessory sleeves, ornamental accessories, and/or a retractable tether can be used with the ambiance lighting system. The GPS, audio-video interface, and communication interface can be used in geofencing and digital media streaming applications.
