Abstract
An off-mains lighting display comprises a plurality of electro-luminescent lamps (ELs) connected in parallel across a rechargeable battery that is connected to the ELs through an inverter. A solar panel device recharges the battery. Electroluminescent lamps for use in light strings are produced by cutting decorative shapes from existing electroluminescent material and mounting them back to back, in receptacles connected to electric wiring as in conventional light strings. For greater protection and ease of use the lamps may be mounted inside a length of clear plastic tubing, or may be laminated within layers of plastic material.
Claims5
A lighting display system comprising:
- a plurality of electroluminescent lamps;
- a battery for powering the system;
- a controller for connecting the lamps to the battery and for varying the operation of the system between different modes having different requirements for electrical power;
- a voltage monitor connected to monitor the output voltage of the battery;
- the controller responding to a fall in the output voltage of the battery sensed by the voltage monitor to switch the operating mode of the system to a reduced power consumption mode.
A lighting display system comprising:
- a battery for supplying electrical power;
- an inverter for converting DC current from the battery to AC;
- a plurality of low power electric lamps adapted to be powered by the battery;
- a micro-controller for controlling the supply of electricity from the battery to the lamps and for controlling the lamps;
- a voltage regulator for monitoring the output voltage of the battery and to provide
- a signal to the micro-controller when the output voltage drops below a predetermined amount.
