Device for emergency lighting refers to lighting technology, particularly to electroluminescent (EL) lighting devices. And can be used for emergency lighting in industrial, public and residential buildings and different objects.

Well-known and widely used system for emergency lighting, consisting of individual lighting fixtures and light signs attached to the power supply, not connected with the network working lighting, or powered from an independent external or local source (battery, diesel generator set and so on), not used in the normal mode to the power working lighting.

Their disadvantage is that when turning on the lighting system lighting and pointers is always turned on and the energy supply is consumed inefficiently.

Known closest in technical essence is a system for emergency lighting on the basis of fluorescent lamps with electronic controller ballast company "Dodeka", for example type EU (supplemental information company "Dodeka", company website http : //www.dodeca.ru). A functional diagram is shown in figure 1.

It contains a power source (battery) 1, which is connected with lamps 2. Each lamp is included lighting fixture (fluorescent lamp) 3, directly connected to the power source 1 through the controller electronic ballast 4 with the voltage Converter emergency source to the supply voltage of the lighting unit (generator voltage) 5 from the control circuit 6.

The disadvantage is that when turning on the lighting system lighting 3 is always turned on and the energy supply is consumed inefficiently. The controller 4 allows you to turn on the lights 2 sequentially or in any desired sequence, for example, creating the effect of a traveling wave in the direction to exit from the premises. However, this requires the use of additional control circuit connected to the input of the control circuits 6 each lamp 2 separate wire that leads to the complication of the installation of the lighting system and additional costs for wire management.

The present invention aims at increasing the efficiency of emergency lighting. This is achieved in that the device for emergency lighting, containing the power source and the lamps, which include lighting device connected to the power source through the voltage Converter source voltage of the lighting unit, and the control circuit of the Converter, according to offer the mu invention additionally introduced delay circuit and pulse generators included in each lamp between the power source and control circuit of the Converter.

The introduction of new elements and relationships between them provide a solution to the task.

Figure 2 presents a structural diagram of the device.

The device contains a power source (battery) 1 and the lamps 2, comprises a lighting device 3, the inverter 4 voltage source to a power supply voltage of the lighting device, the control circuit of the Converter 5, a delay circuit 6, a pulse generator 7. When the power source 1 is connected to each of the lamps 2 Converter 4 voltage source to a power supply voltage of the lighting device 3 and to the input of the delay circuit 6, the output of the delay circuit 6 is connected through a pulse generator 7 to the input circuit 5 to the inverter 4, and the output of the Converter 4 is connected to the lighting device 3.

Figure 3 presents the timing diagram of the operation of the device.

A device for emergency lighting in the following way. At time t1power supply 1 and includes a delay circuit 6 in all lamps 2. At time t2after a period of time τ after turning on the power supply 1 output signal of the delay circuit 6 includes a pulse generator 7 first St. the 2 of these lamps, and its signal through the control circuit 5 includes a Converter 4 voltage source 1 to the power supply voltage of the lighting device 3. The lighting device 3 is switched on at the time τ. Duration τ pulse generator 7 is determined by the required duration of the illumination of one of the lighting unit, and the repetition period of pulses T is the number of consecutively included lamps 2. In the second lamp 2 delay the moment of switching on of the lighting device 3 is 2 τin the third - 3 τ and so on. In other respects the operation of the lamps 2 are similar. This series connection of lamps 2 can create, for example, the effect of the traveling wave in the direction to exit from the premises. If necessary, create different lighting effects, the ratio of the time delay and duty cycle of the lamps may be different.

The proposed device allows to increase the efficiency of the system emergency lighting due to alternately activate the lamps. When all the lamps are connected to a power source, two-wire communication line. Thanks to emerging lighting effects do not require the use of special light signs of evacuation direction.

Device for emergency lighting, containing the power source and the lamps in composition to the which includes a lighting device, connected to the power source through the voltage Converter source voltage of the lighting unit, and the control circuit of the Converter, characterized in that, to improve profitability, it additionally introduced delay circuit and the pulse generator included in each lamp between the power source and control circuit of the Converter.
