Abstract

A bi-voltage emergency lighting system that works as a normal fluorescent lamp in normal conditions and work as a emergency lamp during power failure, comprising a safety fuse (1), a transformer (2) connected to a rectification unit (3) and switches (5, 6) for changing the power supply from the external voltage to an emergency battery (7), the circuit being connected via nverter (8) to a fluorescent lamp (9).

Description

BI-VOLTAGE EMERGENCY LIGHTING SYSTEM TECHNICAL FIELD
The present invention relates generally to the technical field of electronic equipment and more specifically to the field of lighting devices A bi-voltage emergency lighting system that works as a normal fluorescent lamp in normal conditions and work as a emergency lamp in a power failure.
BACKGROUND ART
The state of art comprise fluorescent lamps that work with a voltage only. In case of power failures emergency lighting is used. This emergency lighting is an independent equipment so the user as to buy two different lighting systems, one for normal use and another for emergency situations.
The present invention relates to a lighting system that conjugate in a single device a normal lighting system and emergency lighting system and provide continuous ilumination without interruption. This system presents a electronic circuit capable of operating in a wide range of voltages, equipped with a battery whose capacity is function of the time it must maintain the emergency light on (at least eight hours). When the energy supplie is normal the circuit use it to feed the lamp and to charge the emergency battery. When the energy supplie is interrupted for any reason the circuit changes automatically to the emergency mode beggining to use the battery as voltage source to feed the lamp. The light will stop only when the battery is empty or if the user turn it off in the interrupter. Once the energy returns the batery will again be charged.
The invention uses the electrical instalation of the buiding without any need to perform adaptations in the wiring. Other option of instalation is the circuit be installed far from the lamp, that could be fixed in a lamp holder or equivalent means, also the invention has the advantage of does not need fluorescent lamp reactors. BRIEF DESCRIPTION OF THE DRAWINGS FIG.1 is a scheme of the circuit of the invention.
BEST MODE FOR CARRYING OUT THE INVENTION Referring to the FIG.1 the bi-voltage emergency lighting system have a safety fuse (1) a transformer (2) with primary to 110V or 220 V and secondary with current and voltage outputs suitable to the circuit. The transformer (2) is connected to a rectification unit with diodes (3) e capacitors (4) that change the alternate current in continuous current. Switches (5 e 6) changing the power supply from the external voltage to the battery (7). The circuit is connected for an inverter (8) to a fluorescent lamp (9). When there are external voltage and current the circuit alouds the feeding of the lamp (9) and the charge of the battery (7). To prevent the involuntary discharge of the battery (7) a inverted diode (10) is connected to the switch (6) avoiding the return of current.
Today this invention could be use only with fluorescent lamps, but in the future with the development of really compact batteries with proper values of power it could be use in any building with any kind of lamps.

Claims

WHAT IS CLAIMED IS: 1- A BI-VOLTAGE EMERGENCY LIGHTING SYSTEM comprising a safety fuse (1 ) a transformer (2) with primary to 110V or 220 V and secondary with current and voltage outputs suitable to the circuit, the transformer (2) connected to a rectification unit with diodes (3) e capacitors (4), the circuit using switches (5 e 6) to changing the power supply from the external voltage to the battery (7) and the lamp (9) connected for an inverter (8) to the circuit, to prevent the involuntary discharge of the battery (7) an inverted diode (10) connected to the switch (6) to avoid the return of current and discharge of the battery (7).
