Problems solved by technology

Setting up two drives is disadvantageous for cost and space reasons
Additionally, the need for a separate driver to drive the LED light unit from the battery in emergency mode makes it difficult to add emergency mode functionality to existing lighting systems

Embodiment Construction

[0014] figure 1 Elements of a lighting device providing both a normal mode and an emergency lighting mode are schematically shown. Direct power line AC power 1 provides power in normal mode to a drive 3 optimized for power line power 1 (eg 230 Volts, 50 Hz for EU).

[0015] When the power line relay 7 is closed, power is supplied to the driver 3 at the power line input 4 . The control unit 8 monitors the power line AC power supply 1 . If the control section 8 detects that the powerline AC source 1 is interrupted, or if it determines that it is malfunctioning (operating outside acceptable values), the control section 8 may provide an appropriate signal to the relay control line 9 to open the powerline relay 7 and Close emergency relay 11. The emergency relay 11 allows the lamp 5 to be driven in emergency mode. The driver 3 is preferably an independent driver connected to mains AC power through a mains relay 7 which closes only when mains AC power is available. In a preferr...

Abstract

A power supply system for illuminating an LED lamp unit 5, having a normal mode of operation in which a mains input 4 of a driver 3 of the LED lamp unit is supplied by mains power 1, and an emergency mode of operation, in which the LED lamp unit is supplied by a charge storage device 19, is disclosed. The system includes an emergency mode converter 21 operable to step-up the voltage from the charge storage device and to supply the mains driver input for illuminating the LED lamp unit.

Description

technical field [0001] The present invention relates to a power supply system and method for lighting an LED lamp unit having: a normal operating mode in which the power line input of a driver of the LED lamp unit is powered by mains power; The LED light unit supplies power. Background technique [0002] Various devices are known for lighting systems providing both conventional and emergency lighting. This emergency lighting is intended to be activated when conventional lighting is no longer functional because direct power line power to conventional lighting is no longer available or has failed. Emergency lighting is usually powered by batteries or other energy storage devices. Conventional lighting is controlled by a switch, and the user (or the control system) can control whether to turn on the lighting through the switch. In general, emergency lighting is intended to come on automatically when the absence or failure of mains power for conventional lighting is detected ...
