摘要： While a power supply line from a main power section to a light-emitting section in a xenon flash lamp is provided with a diode in order to prevent a current from flowing into the main power section, there has been a problem that the diode generates heat due to a large current passing therethrough upon power supply at the time of light emission and breaks. When diodes are connected in parallel, the large current can be dispersed, whereby the diodes can be restrained from raising temperature in excess.

摘要： A flashing light warning apparatus, which includes a voltage source (U), a main gate transformer (HW), a flash tube (R), an ignition device (Z), at least one storage condenser (K), and an electrical switching device (S), can be switched to provide light energy for daytime flashes and nighttime flashes in an uncomplicated, cost effective system which produces dependable light flashes. The night flashes have a light energy such that they can be seen from afar only with night vision apparatus. When the switching device turns off voltage production of the main gate transformer or further transmission of voltage from the at least one storage condenser, the ignition device is coupled to an auxiliary gate transformer (ZW) for carrying out light flash production by means of high frequency ignition voltage produced by the ignition device.

摘要： The microprocessor controlled lamp flashing system includes a plurality of flash lamp assemblies for providing lighting effects in response to input control signals from a central processor. The control signals are provided in a data packet with intensity and address signals, and each flash lamp assembly includes a microprocessor which controls a flash control circuit for a flash lamp. Each microprocessor is connected to a preset address circuit which causes the microprocessor to respond to a unique address signal in the data packet and register the intensity signal associated with the unique address signal. The microprocessor controls cooldown of the flash lamp by registering intensity values and deactivating the flash control circuit for a determined cooldown time when the intensity values registered in a time period exceed a predetermined threshold value.

摘要： A gas discharge tube is controlled in intensity and in the length along such tube that is illuminated by providing digital control signals to an analog drive circuit connected to the high-voltage energization device for the tube. A pulse-width modulated digital control signal containing illumination length and intensity information is converted to ramp-shaped analog drive pulse that control the voltage at a high-voltage transformer secondary to which the gas discharge tube is connected. A manually actuatable keypad permits the user to enter the information that is then converted to the pulse-width modulated signal.

摘要： A variable color lighting device employs two gases having different ionization potentials and sealed in a lamp tube. A cathode and anode are disposed inside the lamp tube opposed to each other and connected to a power supply source for varying applied voltages thereto to vary light emitting ratio of the two gases for different color light generation, in accordance with the applied voltages. A variable color lighting can be realized at relatively low voltages with a simple and economical control circuit, and an increased light emission output can be attained to render the device utilizable as a main lighting source.

摘要： A high voltage power source for supplying a DC high voltage to a discharge tube, can detect an abnormality when created at the discharge tube side and stop its output. The high voltage power source is provided with a detector circuit which detects when the DC high voltage is larger than a predetermined reference value and a control circuit which cuts off the output of the DC high voltage in response to the above detection. When an abnormality occurs at the discharge tube, for example, non-operation or unstable operation occurs, since a load becomes lighter than normal, and the DC high voltage to be supplied to the discharge tube becomes higher than normal and is detected by the detector circuit so that the control circuit responds to the detected high voltage and cuts off the output of the DC high voltage.

摘要： A pulse generating apparatus includes a base current supply section for generating a constant DC current having a first prescribed current level for turning on a xenon lamp, and a pulse current section for adding a pulse current having a second current level greater than the first current level and a prescribed pulse duration within a prescribed repetition period to the constant DC current. The base current supply section and pulse current section should satisfy the following equations:1.4.ltoreq.Imax/Imini.ltoreq.60.2.ltoreq.t/T.ltoreq.0.7T.ltoreq.1/40Where Imax is the sum of the first and the second prescribed current levels, Imini is the first prescribed current level, T is the prescribed repetition period, and t is the prescribed pulse duration.When the pulse current added to the DC current is supplied to a xenon lamp, the xenon lamp outputs a strong light during the pulse duration of the pulse current, and a feeble light during the absence of the pulse current.
