The LDM emergency control gear has been designed to be used with most LED Driver powered luminaires so that the luminaire can operate normally with mains power and provide the optimum battery powered light output in the event of a mains failure. With Lithium Iron Phosphate (LiFePO₄) batteries now fitted as standard its small design is well suited for luminaires as they become more compact. The LDM can be provided as a kit and has been designed to be installed inside a luminaire with the other control gear. Alternatively there is a kit option for the LDM to be used remotely from the luminaire when there is not enough space internally.
The LDM emergency LED control gear allows maintained operation of high-power LED modules, when used in conjunction with the standard mains voltage LED driver making it ideal for luminaires that need emergency conversions. The emergency control gear incorporates a module/charger and a high temperature LiFePO₄ battery. In the event of a mains failure an integral 2-pole relay disconnects the LED lighting load from the mains LED driver and then connects it to the emergency control gear which operates the LED module at an optimum light output for the rated duration.
