Definitions

  • the present invention relates to a flashing beacon for alarm systems with a light source containing at least one light emitting diode and a driving this circuit having a power supply, a current transformer and a flash control.
  • Such flashing lights are together with the hazard detectors on the detector bus of the alarm system, for example, together with the fire alarms on the detector bus a fire alarm system.
  • Known flashing lights have a relatively high power consumption of about ten times a scattered light smoke detector. It would therefore be advantageous to use flashing lights with the lowest possible power consumption at a certain effective light intensity. It is obvious that the effective light intensity must not fall below a certain lower limit, for example, when mounting the flashing lights in long corridors, this is often seen at a shallow angle, so that the perceived by the eye light intensity can be very small.
  • the invention will now be given a flashing light of the type mentioned, which has the lowest possible power consumption and thus improved efficiency.
  • the converter current flows through the light-emitting diodes, which is very important because it reduces the power consumption.
  • Another advantage of the inventive solution is that the efficiency is improved by about a factor of 2 and the current and thus the light emission of the flashing light over a large Voltage range of about 12 to 30 V can be kept relatively constant.
  • a first preferred embodiment of the flashing beacon according to the invention is characterized in that the current transformer has a control unit, and that this is connected in series with an inductance, an induction barrier and a resistor.
  • the resistor in connection with the control unit keeps the current to the light source constant during the lighting time.
  • the figure shows in the middle part of a six light-emitting diodes (LEDs) 1 containing light source L, in the upper half of their supply and a current transformer W and the lower part of the designated as flash control B control electronics of the light source 1.
  • the six light source L forming light-emitting diodes 1 arranged in two parallel branches to three LEDs 1.
  • Flashing lights of the type described are often used in combination with an acoustic alarm, such combined acoustic / optical alarms as a "sounder beacon", or in German “Blitzsummer” are called.
  • the flashing light or the flash buzzer is preferably mounted on the ceiling and has a similar shape as the fire alarm.
  • the supply includes a voltage source 2, which supplies a voltage of, for example, 12 and 30 V, and a current limiter 3 for limiting the current supplied by the voltage source 2 to 3 mA.
  • the reference numeral 5 denotes a current memory formed by a capacitor.
  • the current transformer W contains a control unit 4, an inductance 6, a diode acting as an induction lock for the inductance 6 and a diode 7 acting as a current limiter resistor 8, at whose output the light source L is located.
  • the control unit 4, the inductor 6, the diode 7 and the resistor 8 are connected in series.
  • the current flowing to the light source L is kept constant during the lighting time to a certain value of, for example, 280 mA. Once this value is reached, the power supply is interrupted in the current transformer W, switched on again after a few hundred milliseconds, and so on. In this way, the interaction of the resistor 8, the inductor 6 and the current transformer 4 results in a significant reduction of the power consumption of the light source L and thus an improvement of the efficiency by about a factor of 2.
  • the flash controller B essentially comprises a microprocessor 9, which is connected, for example via an ASIC to the detector bus of a fire alarm system and from this an operating voltage of 3 V and all required alarm data relates, and two switches 10 for switching on and off the light source L.
  • the microprocessor 9 controls in case of alarm, the two switches 10 so that the LEDs 1, for example, each for 20 ms and then switched off for 1.2 s.
  • the duration of the switch-on time depends on the temperature. For example, the Switch-on time of the LEDs at a temperature of -20 ° 15 ms, at + 20 ° 20 ms and at + 70 ° 27 ms. This means that the pulse width increases with temperature.
  • This temperature response of the luminous intensity of the light-emitting diodes 1 is corrected by a sensor contained in the microprocessor 9, for example a diode (not shown) for measuring the ambient temperature.
  • a sensor contained in the microprocessor 9 for example a diode (not shown) for measuring the ambient temperature.
  • the ability to drive the LEDs 1 by the flash controller B in certain pulse shapes also contributes to the reduction of power consumption. You can also interpret the pulse shapes for the control of the light emitting diodes 1 according to the degree of attention to be achieved.
  • the two branches with the light-emitting diodes 1 can be alternately turned on and off to give the impression of a moving light source L, or the strobe light can flash sequentially, with pre-flash and main flash.
  • the flashing light described has the advantage of low power consumption, improved efficiency and a fairly constant light emission over a wide voltage range of 12 to 30 V. It has the maximum effective light intensity for a given power consumption and can also in places where they only under one relatively flat angle is seen, which alert there present reliably.
