Abstract: Provided are a solid-state lighting apparatus composed of a plurality of solid-state lighting units. Each solid-state lighting unit includes inter-unit communication modules, each module located on a corresponding side of the solid-state lighting unit and configured to communicate and interlock with an inter-unit communication module of a corresponding adjacent lighting unit connected to the lighting unit on the corresponding side. The invention allows flexible combination and convenient installation/rearrangement of lighting equipment to satisfy requirements for different lighting areas and working modes.

Abstract: Provided are a solid-state lighting apparatus composed of a plurality of solid-state lighting units and a method of operating the same. Each solid-state lighting unit includes inter-unit communication modules, each module located on a corresponding side of the solid-state lighting unit and configured to communicate with an inter-unit communication module of a corresponding adjacent lighting unit connected to the lighting unit on the corresponding side. Each inter-unit communication module includes: a presence detector for detecting presence of the corresponding adjacent lighting unit; a presence indicator for indicating presence of a lighting unit to the corresponding adjacent lighting unit; an optical transceiver for communicating with corresponding optical transceivers in the corresponding adjacent lighting units. The solid-state lighting apparatus is operable to work in either a synchronous or a chain-effect mode.

Abstract: The invention relates to an electrical mobile event lamp. The object of the invention is to design a mobile electrical event lamp for hiring for events, such that same can be used alternatively for permanently wired and battery-powered operation. According to the invention, this is achieved by integrated rechargeable batteries for power supply and a connection for a wiring of the lamp provided for an alternative power supply, as well as a blocking function implemented in the electronic controller of the lamp for access to the integrated battery implemented in the electronic controller of the lamp, and a data connection for activating or deactivating the blocking function by means of an external data synchronization.
