In order to facilitate understanding of the present invention, a detailed description of exemplary embodiments of the present invention will now be described with reference to the accompanying circular.

In FIG. 1, a basic lamp 10 includes a high efficiency small I
Equipped with l'HxD light source and a light source lamp/
J is equipped with an arc-tight blue tube.

The arc tube 711 has spaced apart electrodes 14 extending therethrough in a sealed manner such that a discharge state of [il] is maintained between the electrodes. Also provided is an incandescent tungsten filament stabilizing element lt having two ends 20, here a and here b. This '1j! In the embodiment, one filament stabilizing element with different resistance values is provided, so that the integrated light source can be lit with one illumination intensity of different levels. The filament stabilizing elements lIt and I (ID rung l) are both housed in a light-transparent outer tube. It is desirable to reduce the pressure inside this outer tube. One end of the filament stabilizing element /1 is connected to one input terminal of the aftereffect rectifier J6. The other end of the filament stabilizer/1 JJa, and here b
and the other output terminal J0 of the full-wave rectifier Ko4 are connected to the input terminals J41 and JAI) and JK of the integrated light source, respectively, and these input terminals are connected to AC R/20V, 40Hts household connected to an AC power source.

The high-voltage rung starting pulse generator 0 can be operated by alternating current voltage and has an output terminal forming a high-voltage electrode terminal that terminates in the vicinity of the HID rung. The pulse generator 410 responds to the AC voltage applied between the input terminals JAIL and JOB and 31 when the HID lamp 1 is not lit, and generates a signal in the arc-sealed tube 1 of the lamp/J from H. Generates high voltage pulses large enough to ionize the atmosphere. When rung l- lights up from ①, the pulse generator 〇 will no longer operate in response to lamp lighting parameters such as voltage drop.

The low impedance path means is connected in parallel with input terminals 1 and Jo of the full-wave rectifier.・When the rung/J is lit from ■, this low impedance path means is connected to a predetermined voltage generated between the input terminals Jf and Jo of the full wave rectifier Ra for every half cycle of the AC voltage. In response to the voltage, a low resistance path is formed in parallel with these input terminals Jt and JaK. Since the predetermined voltage that activates this low impedance path qPR+1- is greater than the maximum voltage between the input terminals t and JO of the full-wave rectifier 1 when one lamp is lit, a -H arc occurs within the lamp 1. Then, the low impedance path means 4I-da becomes inoperative. As will be described later, the pulse generation circuit operates according to the time sequence immediately before the activation of the low impedance path, so when an arc occurs between the rung electrodes, the low impedance path + step path becomes inactive. .

The HID x) lighting maintenance device 414 is operated by an AC energizing power source, and is connected to full-wave rectified 4S output terminals J and 3.
It has output terminals t and go which are connected to the output terminals. This lighting maintenance device 6 operates to maintain the lighting of the l1lD rung during the minimum energization period of the full-wave rectifier. In other devices for lighting such a light source, the output of the full-wave rectifier is normally A large-capacity electrolytic capacitor is connected between the terminals to supply current during the minimum energization period of the full-wave rectifier, but the full power efficiency of the device is poor due to the current flowing into the capacitor. .

The circuit shown in detail in Figure 2 is designed to ignite a JO watt high pressure sodium arc discharge lamp, in which incandescent stabilizing filaments/1 are connected in parallel with each other, each filament having a rated/JO watt. , intersection i11/JO
This circuit O input terminals J4 and yt can be replaced with other filaments of different wattages to change the amount of light from the integrated light source. The lamp jJ connected to the AC power supply has the above-mentioned relationship with the arc-sealed tube 1 and the electrode 14.

The incandescent filament stabilizing element 1g also has two ends J0 and a bottom, as described above.

The full-wave rectifier roller has two input terminals (L), 30 (30) and one output terminal (J): 2. Diode bridge with J* (D
/-Dl), and the filament stabilizer /l
The O end 0 is the input terminal 2t of the diode bridge 14.
The other end of the filament stabilizing element/1 is connected to the input terminal J41 of the composite light source (the other input terminal JO of the full-wave rectifier is connected to the other input terminal J4 of the integrated light source). Connected to input terminal Jt.

The high-voltage rung starting pulse generator 3 is operable with alternating current voltage, has an output terminal constituting a high-voltage electrode 41J that terminates near the discharge rung J-O arc tube, and is activated by field effect. Ionizes the atmosphere inside the arc tube. In this example, in order to boost the voltage used in the pulse generation good event, the booster consists of a transformer @T/, capacitors O/, 0, diodes DJ, DJ, and voltage drop resistors R/ and R. The device is in use.

Pulse generation S is connected to diode D and resistor RJ-
energized through a voltage divider consisting of Rj to capacitor OJ
to charge. When the capacitor OJ is charged with *ovl, the diac 81 becomes conductive and triggers the thyristor (try book) 8-, so the thyristor 8J discharges the capacitors 0da and Oj". Therefore, the pulse transformer lever is approximately The 0 pulse generator 〇 generates an ooovo pulse, and this O pulse is applied to a field effect electrode, that is, a high voltage electrode, and ionizes the atmosphere inside the arc bud/II. Become.

The low impedance path means is basically connected in parallel with the pulse generator 4IO, and consists of a voltage divider consisting of resistors R4-Rt, a diac 8J, a thyristor (triac) B, and a capacitor C. . When the capacitor is charged to a predetermined value, the diac BJ becomes conductive and triggers the thyristor θ. This causes the thyristor 8 to substantially connect the input terminal 2 of the full-wave rectifier 1 and the input terminal 2 of the full-wave rectifier
Short circuits on both sides of O. To explain the operation of the pulse generation 〇 and low impedance path means reference in the embodiment shown in Fig. 2, the H/L/S generation a 〇 operates immediately before the operation of the low impedance path + stage goo. It has become.

When the peak voltage is /JOv, the low impedance path 91I
Generally, this device is set so that the pulse generation function 〇 is activated when R is activated and the peak voltage is 0V. When an arc occurs in the discharge lamp S, the voltage between the input terminals of the full wave rectifier 24 and 317 does not rise to a sufficient voltage to energize the low impedance path+stage 411. . Once the low impedance path means 4I4I is activated, it short-circuits the input terminal of the full-wave rectifier No. 2 and the circuit across 300, and the filament stabilizing element /1 is energized for the remaining half cycle to complete the circuit. It becomes incandescent.

As mentioned above, in a device using a large-capacity capacitor connected in parallel with the output end of the full-wave rectifier No. 2, the power factor is originally relatively low due to the current flowing into the capacitor. Since such a capacitor is omitted in the design of the present invention, a current source must be provided to keep the rung/# lit during the minimum energization period of the full-wave rectifier roller. Capacitors 01 and 09 and diodes Di and D? constitute a voltage doubler for terminals J4 and St. achieved by. The output of this O voltage doubler circuit is the current limiting resistor R.

It is continued.

To summarize the operation of the embodiment shown in FIG. 1, first, after power is turned on, any one of a number of brightness levels determined according to the incandescent filament provided in the circuit can be selected. In the half cycle, a high voltage pulse is applied to the high voltage electrode for starting the field effect outside the arc tube/41. In case of cO, the main current flow is through full wave rectifier-6. During the minimum energization period of the full-wave rectifier, the rung current is maintained at the minimum value for maintaining lighting by the minimum value for maintaining lighting.

If the power is temporarily cut off after the lamp has reached the operating temperature, the filament stabilizing element connected directly to the power line by the action of a low impedance path means for voltage detection
The low impedance path through which the light is emitted from stage 4 and the pulse generator are both activated every half cycle of the energizing voltage, so that the electronic circuit repeatedly attempts to restart the warm discharge lamp. When the lamp is restarted in a cool condition, the pulse generator DA0 and the low impedance path means Q are automatically deenergized. Once the discharge in rung j is started, rung j- and filament stabilizing element it are in series. Since the voltage generated across the discharge lamp jJ is low, the filament stabilizing element it initially becomes incandescent with high brightness, but as the lamp warms up and the voltage across it increases, the filament stabilizing element /l becomes incandescent. As the light output from - increases, it becomes progressively dimmer.

A greatly simplified device is shown combined into one unit. When a voltage above the breakover point is applied, the voltage sensing switch element is turned on through the negative resistance region to a low voltage on state. The conduction with the next current continues until the current is cut off or falls below the required holding current value. Therefore, O is applied once every half cycle, and the switch element becomes conductive at a predetermined voltage, and this conductive state is maintained until the current reaches its minimum value. This switch element is sold under the trade name Cydac (B-0-M0) by Tetsukar Electronics, Dallas, Texas, USA.

The circuit shown in FIG.
The D-rang consists of a sealed arc tube 14I, and one electrode 6 passes through this arc tube 14I in a sealed manner, during which a high-intensity discharge is maintained.

The incandescent filament stabilizing element /la has two ends J0 and here, and the full-wave rectifier rILS has one input terminal 2.
1 and 30, and one output terminal here and 3 terminals. One end of the filament stabilizing element /1& is connected to the input terminal 2g of the full-wave rectifier Koro, and the other end 2 of the filament stabilizing element lt1 and the other input terminal 30 of the full-wave rectifier @24 are connected to the light source input. It is connected to both ends of the terminals 36 and 3t, respectively.

The above-mentioned low impedance path means is the switch 14, and the voltage at both ends is /0-/JO1.
The zero pulse generator, which becomes conductive when lK, is coupled to the switching element j1 and consists of a pulse transformer 3 and a capacitor O10.

When the side switch element conducts, capacitor 01
0 discharges and generates one high voltage pulse every half cycle of the energizing voltage O. This high voltage pulse is applied to the field effect electrode. Lang! Regardless of whether the switch starts or not, the incandescent filament stabilized element /1* closes the switch element j1 during the remaining half-cycle because it forms a very low impedance path. When S6 pauses again, it becomes incandescent.

When considering the operation of this circuit, the nominal voltage of the power supply is /7V (effective value), /4jV (peak value), and the output capacitor 0/ of the current source for starting assistance and lighting maintenance is fully charged ( The discharge rung 3 is in a cooled state, and the nominal breakover voltage of the SIDAC switch element 36 is set to 7301. When the power supply voltage increases sinusoidally, capacitor 010 is charged to a voltage approximately equal to the power supply voltage. Power supply voltage is /J

If short-circuited by 6, the lamp current cannot flow from the full wave rectifier @2b.10 By appropriately selecting Oli products in the auxiliary current source, the arc tube/da It can conduct electricity even during the minimum energization period. At this minimum point, switch element j4 returns and the rectified supply voltage R1 passes through the currently conducting discharge rung during the next half cycle. The role of the auxiliary current source O after this rung start is the same as that of the embodiment shown in FIG. That is, the purpose is to supply a "lighting maintenance" power R1, to the discharge lamp while the power supply is stopped. When the discharge rung is lit, the starter or low impedance path is in the dormant layer because the voltage at the "discharge rung input line" is not high enough to cause breakover and conduction of the SIDUCK switch element j4. A more realistic shape m for rung starting is the initial discharge shape [
