A light-emitting device comprises a casing including an upper surface portion having one or more first through holes, and a front surface portion having an opening; a transparent member that closes off the one or more first through holes; one or more light-emitting elements that face the one or more first through holes, respectively, within the casing; and a lid member provided so as to close off the opening, wherein the casing is integrally formed using one material.

The present invention relates to a replacement LED light module with a plurality of LED lights on a PCB board is attached to a heat sink, providing good heat dissipation and provide an easy installation mechanism using magnetic supports that can be quickly put in place to difficult locations, such as ceiling, where there is suitable magnetic flat surface for the magnetic attraction to take effect. The power wires, along with the wire nuts, provide a sort of “back up” tensile support in the event where the magnetic connection may lose its pulling power.

Retrofit kits for retrofitting LED light engines into existing light fixture housings. The retrofit kit includes a hook bracket that may be mounted in the housing and from which an end of the LED light engine can be suspended so as to permit an installer to electrically connect the LED light engine. The retrofit kit also includes a mounting bracket to secure the free end of the LED light engine into the housing after the LED light engine has been rotated upwardly into the housing from the hanging position.

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 lighting device (10) for operating from a main power supply or from an auxiliary power supply (25), in co-operation with a switching device transmitting a wireless control signal indicative of a power condition of the main power supply. The lighting device (10) accommodates in a single housing (11) a light emitting module (20), the auxiliary power supply (25) and a control circuit (30) for monitoring the wireless control signal and a power condition of the main power supply at the lighting device (10). The control circuit (30) is to operate the lighting device from the auxiliary power supply if both the monitored power condition and the control signal indicate absence of power, and is to deactivate the powering from the auxiliary power supply (25) if the monitoring reveals presence of power of the main power supply.
