Abstract

A Led lighting system comprises LEDs 111,112, an electronic driver 13 and an emergency socket 14 that is directly connected to the LEDs, bypassing driver 13 and allows the LEDs to be driven by an external emergency power supply in the event of a power cut. The emergency supply comprises batteries 22 and a circuit 21 that detects a power cut and drives the LEDs using the battery as a source. The battery can be rechargeable and the emergency pack can contain a battery management circuit to control its charge and discharge and an LED to indicate the battery status. The status indicator LED 112 can be fixed to the lighting system and a circuit board 11 and driven through the socket 14. By the addition of a plugged-in emergency module a lighting system that runs on mains voltage can be converted to an emergency LED lighting system.

Description

Description:
A complete self-contained LED lighting system enabling a LED lighting system to become a Maintained Emergency LED Lighting system without modifications being made to the components, circuitry or wiring of the original lighting system.
[a] Background to the Invention
Previously the conventional way to convert a standard mains voltage light fitting [luminaire] to an emergency maintained unit required the luminaire wiring and components to be modified and or added to [cables removed, replaced, changed and added, creating a new wiring loom]. In addition for most conversions additional components were needed to be added to the existing electrical circuit. These modifications are not of the type that can be done easily or at all on site to previously installed luminaires.
[b] Detailed Description of Invention
[a] An LED self contained Lighting system consisting of a control tray fitted with the LED's and control gear and relevant circuitry and cabling to run as a conventional mains powered luminaire. In addition, circuitry to run the control tray in an emergency lighting state, is fitted, which is activated by the "plug in" emergency dedicated module. No additional circuitry or modifications to the existing circuitry is required.
[c] Examples:
An example of the invention will now be described by referring to the accompanying drawings Fig I and 2 Figure 1 illustrates a typical arrangement of the current invention. The luminaire [fig 1] in the form of a LED down light is a self-contained LED lighting system, it consists of: a LED circuit board [11], which include one or more LEDs [111] that are for the illumination purposes and a green LED indicator [112]; A heat sink [12] that is closely attached to the LED circuit board for heat dissipation; A Electronic LED driver [13] with its input to be connected to mains supply and output adequate current to driver the LEDs (not including the green LED indicator); 4-wire cable and emergency socket [14], that is connected directly to the LED circuit board [11] by-passing the LED driver [13], this cable allows the LEDs [111] and LED [112] indicator can be driven by external sources, such as the plug in emergency pack [fig 2]; Optical lens [15] fixed to the front of the LED5; and the luminaire body [16]. Once wired to the mains usually via a switch, this luminare [figi] is fully operational as an integrated LED down light.
To convert such LED luminaire [fig 1] into a maintained Emergency LED luminaire, an external Emergency Pack [fig 2] need to be plugged to the Emergency Socket [14] on the LED luminaire. The said Emergency Pack [fig 2] consists of Emergency control module [21], which has the functions of, a) battery management. b) Driving LEDs through batteries in the case of power cut c) Driving LED indicator for the indication of battery status, this module connects to un-switched mains supply with the live and neutral cable; battery [22]; 4-wire cable and plug [23] that connects the emergency socket, via which the LEDs [111] and LED indicator [112] can be controlled by the emergency pack. Configuring the self-contained LED luminaire [fig 1] and the emergency pack [fig 2] to become a maintained Emergency LED lighting system involves the following steps: 1. Connect Live of the Luminaire to switched Live.
2. Connect the both neutral (luminaire and Emergency pack) to mains neutral 3. Connect the Live of the Emergency Pack to un-switched live 4. Plug-in the emergency pack to the emergency socket of the LED luminaire.
In the normal operation mode: the Luminaire [fig 1] can be turned on and off through a switch connected to the switched live, and the emergency module [21] keeps the battery [22] fully charged, and lights the green LED indicator [112] showing the battery [22] in good status. In the case of power cut, the emergency pack switches to emergency mode and lights up the LED's [111]with the batteries [22] and its built-in driver, the LED indicator [112] is not illuminated in this case. a
