Description of the invention (4) However, the discharge is normal. However, when lighting, for example, about 125V, because the voltage is about the same, the parts need to be large. For the gate between b 100, it is necessary to make the capacitor but the problem is also identified according to the same. In addition, the same. In addition, when the voltage is always turned on other than the voltage, and the conditions 〇1, 〇 are not normally discharged, and any discharge lamp is not it's the same, it can prevent the abnormal discharge from continuing to operate in the above configuration at the rapid start. Capacitors, which constitute a sharp and expensive peak-to-peak voltage, must be appropriate. Two voltages of 50 to 50 are at a normal partial voltage ratio to make the voltage across the discharge lamps 6, 10, and about 95v in a normal moving fluorescent lamp 40W. In the voltage detection circuit p100 of the voltage between the 32WHF device and the electric peak between the two ends of the discharge lamp 6, 10, the voltage detection circuit P100, because of the voltage of a100 and the voltage Act on the gate fluid 6 2 Select the capacitance ratio between capacitor 51 and capacitor 50.

Explanation of the invention (5) The voltage of the secondary winding is also the problem that the peak voltage also changes when the discharge lamp of the inverter's electric load circuit is abnormally lit. The present invention In order to solve the problem of cheap and small parts of the circuit, the present invention is not provided. The output power of the circuit is measured during normal lighting, and the protection circuit is also provided. The present invention is provided for the normal lighting and abnormal voltage of multiple discharges. The difference and the installation change can be the same. The present invention is set to be useful for the difference between the output voltage of the positive test circuit of the discharge lamp under multiple branches. Among the third lamps that operate at different times and different pressures, all the conditions of the lamp-like condition are checked. The fourth discharge lamp is often lit. The purpose is to improve the reliability with respect to the outside when lighting is often performed. The purpose is to remove the condition of the peak discharge lamp of a certain state and measure the abnormal state. The purpose is to remove the and abnormal lighting and install all the voltage measuring circuits. When the detection is reduced, the driving voltage of the switching elements 2 and 3 is reduced, the oscillation frequency of the circuit is changed, and the residual discharge lamp current is also changed. As a result, it has voltage detection circuits P1 00 and P11 0 during normal lighting and between values. The first purpose of the obtained electricity is to provide the spike-to-peak voltage detection obtained by constituting the peak-to-peak voltage for a discharge lamp lighting installation. §Fl has sufficient margin for a discharge-lamp lighting installation to detect the remaining There is no difference in the detection voltage between the output conditions of the voltage detection circuit between the discharge lamps. For one type of discharge lamp, one can be installed, and the detection of the condition of the discharge lamp between the peak-to-peak voltage detection of the remaining state should be simple and convenient.

Instead, it becomes conductive, and when the voltage rises at the end of the life of the discharge lamp, the voltage obtained by the capacitor 158 becomes conductive. If the gate fluid 62 becomes conductive, the current flowing through the secondary windings 5b, 9b of the reactive current coils 5 and 9 to the gate of the switching element 3 via the resistors 1 3 and 15 passes through the pole body 6 3 and the gate fluid 6 2 Bypassing, the switching element 3 becomes non-conducting, and the inverter circuit stops oscillating. Also, "Stop Vibration" also keeps the current flowing to the brake fluid 62 through the resistor 64, and maintains this state until the DC power source is turned off and then on again. This prevents the discharge lamp 6 from operating in a state where abnormal discharge continues. In addition, as described above, the case where the discharge lamp 6 is not normally discharged, but the case where the discharge lamp 10 is not normally discharged and the case where any of the discharge lamps are not ^ 4 discharge, can also prevent the abnormal discharge from continuing.

Description of the invention (17) The bipolar body 152, the newly inserted thunder, and the resistance 71 between the resistance 70 and the resistance \ ^^ and the secondary winding 5b of the fish. # 电 令 为The connection point of 151 and the resistance 7 of the secondary winding 9b are at 0 = two, and the input of the peak-to-peak voltage detection circuit P12〇 passes through ; The secondary winding 5 and 9b of the current coils 5 and 9 are installed at the end of the electric current 〇, the right discharge lamp 6 is normally lit and the discharge lamp 10 becomes a life ί2〇; The detection circuit points the other person on the anode of the diode 1 56 when the normal lighting is abnormal and abnormal 6 1. Mouth 0: 2: peak-to-peak voltage 'if the Zener diode is properly selected Φ 5ΛΗ1 ηη a resistance 5 9 When all the discharge lamps are normally lit, the protection lamp I will not operate. Only when the discharge lamp 6 is normally lit and the discharge lamp 10 becomes 芎; when the abnormal lighting such as 1 period, the protection circuit H100 is activated. Make the frequency converter stop the oscillation of the circuit. It is only normal to strictly protect the discharge lamp 10 from the abnormal discharge of the discharge lamp 6 at the end of its life and the discharge lamp 10, and the hoisting of the discharge lamp, and all the discharge lamps become abnormally lit. The circuit H1 〇〇 action can stop the inverter circuit-it is not necessary to correspond to the discharge lamp load circuits L100, L110, respectively, corresponding to the sighing peak-to-peak voltage detection circuit, which can be made small and cheap. 550976 Schematic illustration Fig. 1 shows a first embodiment of the present invention.
