At night φ, 4 ′, the value of resistors 52 and 57 is selected to be equal, then this midpoint q /; 5: Γ becomes zero. That is, the voltage of the capacitor 54 is as shown in Fig. 9 C c). The outline is as follows: η sample 丨 The mountain is zero, because the discharge lamp 11 is also normally lit, and the weight of the pole body 50 is on the capacitor 53. The obtained voltage V53 and the over: pole body 5 = and the voltage V58 obtained from the capacitor 58 is shown in Figure 9 (a). It can be compared to a voltage that is roughly equal and has a different polarity. The capacitor &amp; voltage V54 is such as The outline shown in FIG. 9 (c) is zero. That is, in the modal operation, let the voltage V54 of the capacitor 54 which is the output of the P detection circuit P100 be ', zero. In the holding circuit Hi 10, the voltage v54 of the capacitor 54 input to the connection point between the cathode of the diode 47 and the anode of the diode 49 satisfies the following formula (3).

2004219 41 Fifth invention description (29) However, the symbol of formula (3) represents the following V54 (modal 1): capacitor 5 4 in the dynamic voltage condition of modal 1 in Fig. 9 and V s 1, V s 2 is expressed by the above (1) and the input voltage of the holding circuit Η110 satisfying the above formula (2). In the condition of the NPN transistor 43 and the PNP transistor 44, the oscillation stop terminal s of the oscillation control circuit 4 cannot be ON, and the oscillation operation of the oscillation circuit 4 continues, and the discharge lamp 7 gates = Quasi-all oscillation control electricity. The 11 and 11 series continue to be normally placed in the above description. It is obvious that in the state where the discharge lamp is in a positive &amp; operating state without depending on the type of the discharge lamp, the periodic discharge voltage is a voltage that is roughly equal to a voltage of zero. Identified as the normal discharge state energy 54 to the oscillation of the circuit. "Things can continue to be reversed." In Fig. 9 ", the discharge substance of coupling person a of discharge lamp 7 is consumed, and the discharge lamp u is constant: = wire to explain. The period of operation description of mode 2 is The discharge substance from the filament is considered to have been consumed. In this action: Valley: 6 side 9 (b) of t21 ~ t22 (ΐ22 is an inverting circuit as described later), the negative half cycle of the discharge lamp 7 The discharge is :: The discharge voltage of the second cycle is larger. That is, the 9 + voltage is positive than the + phase, because the voltage with the capacitor 53 is the absolute value of the voltage V58.

9 (c) becomes the negative potential D. Here, if the Zener voltage of the Zener diode 46 of the holding circuit H1 丨 0 can be satisfied by the above formula (2), it is because When the negative voltage Vs2 is small (the negative absolute value is larger), the pNp transistor ^ system becomes ⑽ ▲, k, and $ ground evaluation N transistor 43 also becomes 0N. Therefore, the oscillation stop terminal S of the oscillation control circuit 4 system It goes to a low level and the oscillation operation is stopped. When the oscillation operation of the oscillation control circuit 4 is stopped, the oscillation operation of the inverter circuit is also stopped (time t22) 'and the discharge lamps 7 and AU are turned off. In this case, the PNP transistor 44 and the NpN transistor 43 are driven from the control circuit.

Next, in Fig. 9, an operation in which the discharge substance of the filament on the negative side of the DC power supply 1 of the discharge lamp 7 is in a consumed state and the discharge lamp 11 is in a normal mode Su 3 will be described. The operation period of the mode 3 is from the time 13 to 14 in the figure. At the time t31 in the middle of the period, the discharge substance of the filament on the negative side of the DC power supply 1 of the discharge lamp 7 is regarded as consumed. In this operating state, as in ^ from 131 to t3 2 in FIG. 9 (a) (t32 is the stop of the inverting circuit 2 as described later; time), the discharge of the positive half cycle of the discharge lamp 7 is not performed. The voltage is greater than the discharge voltage of the negative $ period. That is, because the absolute value of the voltage V53 of the capacitor 53 compared to the voltage V58 of the capacitor 58 = the voltage V54 of the container 54 is a positive potential. The voltage is large here, because if the Zener voltage of the holding circuit 丨 丨 〇 is selected to be full; 1 When the above formula is selected, the NPN transistor 43 will become 0N when it is larger than VS1 beforehand. Continue The ground p = also becomes 0N, so the vibration control of the vibration control circuit 4 stops the electric power, and the vibration exhaustion is stopped. If the "control circuit" becomes low, the oscillation operation of the inverter circuit also stops = the operation is to stop the lamp 7, and the U series lamp. Moreover, at this time, because: (2): and the discharge NM transistor 43 is driven by the control circuit driving voltage ^^ = 44 and the current flows, so this state is continued to the second plant of the direct production resistance 40 and stopped The control circuit drives the voltage VCC until the supply. &quot; L power supply 1 is disconnected and stopped in the above 5 children's instructions, although the discharge substance of the discharge lamp 7 is consumed and the discharge lamp η pole side ν ι $% of the total sum 2004219 41 V. Description of the invention ( 32) Ming ', but even if the discharge lamp 7 is normal and the discharge lamp 丨 丨 The filament weaving discharge substance on the negative side of the DC power supply 1 is consumed or the discharge substance on the filament side of the negative side of the DC power supply 1 of any discharge lamp is already In the case of consumption, it is obvious that the capacitor 54 can be obtained so that the NPN transistor 43 of the holding circuit hi 1 〇 can be given 0N (continuously, the PNP transistor 44 can also be given 0N). The positive voltage is V + 54. In the above description, it is obvious that in the operation state of the mode 3, when the discharge substance of the filament on the negative side of the DC power source 1 of the discharge lamp does not depend on the type of the discharge I, the capacitor 54 is used. It is possible to obtain a positive voltage V + 54 that satisfies the above formula (1), and output the low level from the holding circuit HU0 and stop the operation of the inverter circuit, and the abnormality of the discharge lamp can be avoided. The type of the lamp and the voltage of the capacitor 54 of ± p check P1 00 is if any discharge lamp is normal π "roughly zero, the coupling power of at least one of the discharge force _, 仟 discharge material is consumed The voltage of V-54 can be obtained as Α κ, and the voltage of the formula, and the discharge substance of the filament on the negative side of at least one of the discharge lamps ^ 1 is consumed and the electric current is used as V + 5 4 which satisfies the voltage of the above formula (1), and the oscillation operation can be continued when the discharge lamp of the reverse phase &amp; ^ 糸 available section is normal.

As described above, "If the rated current of the discharge lamp is roughly equal according to the fourth embodiment of the present invention, the amount is $," because of the E force). The discharge lamps of different plural types are at the same point.

Therefore, it is not necessary to optimally select the circuit constant of 010 $ for each type of discharge lamp, which can reduce the types of parts used in the production of lighting devices and the types of in-house management machines. It is optional. In the present embodiment, although the case where the discharge lamp is two lamps is used, two, ^^ Needless to say, even when the discharge lamp is one lamp, it is not necessary.

Moreover, although the ± ρ detection circuit P100 is provided in common for the discharge lamps 7 and 丨 丨, it is obvious that this can also be set individually for each discharge lamp, and its output can be passed through the diode It is connected to a wired OR gate and output to the holding circuit H110. Moreover, since the ± p detection circuits are individually provided to correspond to the respective discharge lamps, even if, for example, the discharge substance of the discharge lamp 7 is connected to the filament of the capacitor 6 side, the discharge substance is the same as that of the discharge lamp. When the consumption of the discharge substance of the filament connected to the negative side of the DC power supply 1 occurs in a very rare occurrence at the same time, the ± p detection circuit can be installed individually. Therefore, it is installed from the discharge lamp 7 Among them: the tp detection circuit can obtain a negative detection voltage, and a positive detection voltage can be obtained from the ± p detection circuit provided in the discharge lamp 11, and the holding circuit Hi 1 0 can be reliably acted to perform a protective action. Moreover, if the resistances 52 and 57 are selected to be equal, although the voltage V54 of the capacitor 54 when the normal discharge lamp is installed is roughly zero, because if-

Description of the invention (36) When the lamp is lit, the voltage of capacitor 97 is R 9 5 · Resistance value of resistor 9 5: Resistance value of resistance 52 V53n: Voltage of lightning arrester 7 and 53, 11 Any one of the lamps is the capacitor point at the time of normal discharge. The discharge lamp of at least one of the discharge lamps 7, 11 is the voltage of the capacitor 53 when the lamp is turned on. The discharge lamp is not 7.11V. —It is explained by the tactics, but it is obvious that because the discharge substance of the filament at the end of the life of the discharge lamp is a consumed discharge lamp phase circuit = = = the ground is reversed, so the two, σ, 鏖, and 员 members are omitted. The open circuit to the direct power supply 1 is shown in Fig. 10: and the operation mode 4 is explained. If the circuit 4 is to be switched to the direct power supply 1, the lighting can be achieved by the oscillation control system. And 3 series are driven by high frequency and discharge lamp discharge lamp, there are 4 :, :::, between the period shown, and the time "1 in the cycle is roughly :, and two reasons and its discharge voltage In order to prevent the voltage between the positive and negative half voltages V53, as shown in Figure 11 U, (b), although the negative polarity of the capacitor 53 is 60, the voltage V58 corresponds to the positive and negative half cycles and is positive.

T ^ is opposite and the absolute value is roughly equal. The magnitude A of the absolute value is larger than the normal lightning # k, 4 ^ The impedance becomes larger and ^ This is because the discharge lamp has an equivalent oscillation action in order to not discharge the electric lamp load circuit The sharpness of the end of the vibration becomes large and the spectrum vibration is used to show, = so. In such operation mode 4, the voltage V54 which is not 54 as shown in FIG. 11 (c) is roughly zero, and the inverting circuit cannot be turned on. Page 41 2148.6139-PF (N2); Ahddub.ptd 2004219 41 V. Explanation of the invention (37) Stop the vibration surplus. Test electricity = = Test circuit V0v1, the container 97 is integrated: = with electricity_, and the cathode of electricity, so if you will; electricity; _ zener diode The body ㈣ * t Μ Λ, h, g. Then in the output of the overvoltage detection circuit Vovl 00: "Large soup batch than the predetermined„ v97abn: Λ surplus of circuit 4, stop. That is, the discharge lamp 7 絚, and Continue the cricket-like evil until the DC power source is disconnected. ',, I The ratio of the positive and negative half-cycles of the voltage ratio I is roughly equal and / or the size is larger than the positive book 4, as shown in Figure 丨 (d) As shown, the continuous time T1 (t41 ~ t42) until the phase circuit is stopped is the capacitance value of 1§53, which can be expressed by the above equations (4) to (6). 2 Zener diode 98 The Zener voltage Vz98, the resistance 95, and the resistance value are set. For example, the capacitance value of the capacitor 5 3 is zero (the same as the capacitor 5 3 is removed). At this time, T1 is zero, and when the value predetermined by the above formulas (4) to (6) is satisfied, the operation of the inverter circuit can be stopped without a time delay. Moreover, if the capacitor 53 is appropriately selected, The capacity value can correspond to the capacity value of the electric valley is 5 3 to stop the vibration of the inverter circuit

The time until now is delayed. T As described above, 'if according to the fifth embodiment of the present invention, because the positive and negative imbalance of the discharge voltage of the discharge lamp is detected, the ρ detection circuit P1 0 0 and the overvoltage detection circuit that detects the magnitude of the discharge voltage ν〇V1 0 0 The two detection voltages are used as the input voltage of the holding circuit Η1 2 0 to identify the discharge

If the discharge is constant, the inverter circuit can be continued Oscillation stops. If any discharge lamp is $, the vibration of the inverter circuit can be stopped. '' Therefore, even when the rated currents of the discharge lamps are roughly equal and the rated voltages (rated power) are different types of discharge lamps that are lit by the same stringent device, a simple circuit configuration is used. To detect the abnormal state of the end of the life of the type of discharge lamp and the occurrence of cracks in the discharge lamp, the operation of the inverter circuit can be stopped. Therefore, it is not necessary to select the type of the discharge lamp to optimally select the circuit constant of the holding circuit H12, and it is possible to reduce the number of types of parts used for the production of the lighting device and the type of the in-house management machine. Further, in the above description, although the case where the discharge lamp is two lamps is explained, it is obvious that the case where the discharge lamp is two lamps is possible, even if it is three lamps or more. And, ± P detection circuit? 1 00. The overvoltage detection circuit Vov100 and the holding circuit H120 are not limited to the structures described above, and needless to say, even other structures having equivalent functions may be used. In addition, although the overvoltage detection circuit Vovl 00 is configured to input the voltage of the capacitor 53 of the ± p detection circuit, even if this is divided into ^ and inputted to the holding circuit hi2〇 through a zener diode ^ The same effect can be obtained at the base of the electric body 44. Embodiment 6: Connection / 1! Is a diagram showing electricity of a discharge lamp lighting device according to Embodiment 6 of the present invention: a diagram. In Fig. 12, components and constituent elements having the same functions as those in Fig. 6 of the fourth embodiment are given the same reference numerals, and description thereof is omitted. Page 43 2148-6139-PF (N2); Ahddub.ptd 2004219 41 V. Description of the invention (39) The present yoke-shaped evil system is in the fourth embodiment, in which all the discharge lamps are unsafe and light, In the case of a lamp device, the oscillation of the inverter circuit is stopped, and in the case of a discharge lamp with at least one lamp on the female I, the detection circuit Lal is installed in the discharge lamp with a vibratory action of the inverter circuit. 〇. . In Fig. 12, 'the presence or absence of a discharge lamp detection circuit La 丨 〇〇 is connected to the capacitor 53 of the ± p detection circuit P100 in parallel with a series circuit of resistance 101 and 102, which is not the same as the NPN transistor 103. The base is connected to the resistor ιοί; [〇2 of the connection, the emitter is connected to the negative pole of the DC power supply i, the collector is connected to the control circuit drive voltage Vcc through the resistor 105, and the NpN transistor is respectively The earth pole is the collector of the NPN transistor 103, the emitter is connected to the negative pole of the DC power source 1, and the collector is connected to the cathode of the diode 仏 of the holding circuit HU0. =, To add to Mara Capacitors 6 and 10, to connect resistors 106 and 107 in parallel, and to connect resistor 108 to the switching element 2. Xichunqi: ow: The operation of the sixth embodiment of the present invention will be described with reference to FIG. 12. Any of the lamps 詈 mr? 7, and 11 have not been installed in the discharge lamp lighting. Whenever the DC power supply 1 is turned on, the control circuit driving voltage Vcc is omitted by omitting. Because any discharge system is zero. Therefore, because the discharge lamp has: installed the second power ^ H103 ^ ^ OFF. NPN t ^ ^ 1 After all the discharge is strict and the lamp is oscillated to start, then if all the discharges are pulled out, and the same vibration Lu stopped. Next, a case where only the discharge lamp 7 is mounted will be described. as long as-

2004219 41, description of the invention (40) __ When the DC power supply 1 is turned on, the circuit drives the voltage Vcc by omitting the illustration. The capacitor 53 is connected to the DC power source i, the control circuit 108, the anti-current coil 5, the resistor 106, the resistance of the discharge lamp 7, the resistance wire, the resistor 92, and the diode 51 to flow and charge electricity. The lamp of 1 V53. At this voltage V53, the transistor 103 is used as the voltage: Shi Sheng sets the constants of each component, and the transistor i 04 series becomes 0FF = Chen Shi ^ Also select the oscillation stop terminal S of the circuit 4 to a high level, The reverse electrician 1 is also oscillated by the discharge substance of the filament. At the end of the life, the action of the ± P detection circuit P1 00 makes the oscillation == the vibration stop terminal S of the circuit 4 to a low level, and the state is the same as the second state and the fourth state. In the fourth embodiment, 'the DC power supply 1 is disconnected in order to remove n from this state, and the discharge lamp 7 is exchanged with a normal product and then re-injected: a direct current, but a plurality of discharge devices and other In the case of electrical equipment, the power supply to the two electrical equipment is disconnected. I # 糸, in this way, even if the DC power is turned on as usual, if the defective discharge lamp 7 is removed from the discharge lamp production device, it will be driven from the control circuit because the NpN transistor 104 is ^ = 0N. The voltage Vcc continues to flow through the PNP transistor 44 and the NPN transistor 43 through the resistor 40. The current flows through the NPN transistor 104 and the NPN transistor 104 cannot maintain the ON state, while the pNp transistor μ and NPN Each of the transistor 43 series became OFF. Second, if the positive # discharge lamp 7 is installed, the swollen transistor 104 becomes 0FF and the inverter circuit ^ oscillates again. Also back ”In the above description, although the discharge lamp 7 is only 1 lamp,

2148-6139-PF (N2); Ahddub.ptd Page 45 2004219 41 Description of the invention (41) The operation to the discharge lamp lighting device or the place where it is unplugged is explained. When the discharge lamp 11 is installed, it is very Obviously, even if it is a discharge lamp; 2 of 7, and 11 lamps, and 3 or more discharge lamps are possible. Further, it is obvious that the overvoltage detection circuit v 丨 00 described in the fifth embodiment can be added to the sixth embodiment of the present invention. In addition, the discharge lamp has an I = built-in detection circuit, which is not limited to the structure described above. Needless to say, even if it is' = other structures having equivalent functions, it may be used. Moreover, although it is not shown in the figure: After the abnormal state of the discharge lamp is detected, when the discharge lamp has been unplugged in order to exchange it with a normal product, if the NPN transistor 10 is used as ⑽, the two oscillations are controlled. If the circuit's warm-up timer is reset, the warm-up timer can be activated at a specified time when restarting. τ 'As described above, if according to the sixth embodiment of the present invention, since the discharge lamp lighting device is installed with at least one discharge lamp, it is possible to oscillate the inverter circuit, so it can be oscillated. The discharge-prevention lamp is an undesired operation when all are not installed. In addition, even when the vibration of the inverter circuit is stopped by detecting the failure of the discharge lamp, the DC power supply 1 does not need to be disconnected. After the discharge lamp is removed, if the discharge lamp is normal, it can be re-used. The inverter circuit is started, so the operation of other electrical equipment connected to the same power supply system as the current lighting device can be performed without any change in the discharge lamp. , ~
