Abstract

An ignitor is proposed, and can be applied to various types of high intensive discharge lamps, wherein electricity is inputted from a power source to a voltage level controller and a pulse modulator of the ignitor. When the voltage level controller becomes loop-closed upon receiving the inputted electricity, the pulse modulator initiates a charging process. If a charging voltage of the pulse modulator is larger than a breakover voltage of a trigger electronic element in a pulse generator, the trigger electronic element becomes conductive to produce and transmit a breakdown voltage to the pulse modulator where the breakdown voltage is flexibly modulated. The modulated breakdown voltage is elevated by a self-couple voltage transformer associated with a discharge lamp until making the discharge lamp become conductive. When the trigger electronic element conducts, the voltage level controller connected to the trigger electronic element is allowed to obtain excess charge and served as a discharge capacitor. Thereby, as the trigger electronic element produces a breakdown voltage, another pulse voltage is accordingly inputted to the pulse modulator. As a result, the ignitor of the invention is advantageous of providing flexibly modulated pulses in compliance with the start-up conditions for a multiplicity of high intensive discharge lamps.

Description of the invention (1) [Field of the invention] The present invention relates to an electric lamp triggering device, and more specifically, it relates to an electric lamp triggering device capable of activating various high-pressure gas discharge lamps. BACKGROUND OF THE INVENTION For homes, office buildings, streets, parks, squares and other places, lamps have become indispensable lighting equipment. Due to the rapid development of technology, light sources have been introduced from the early tungsten light bulbs, fluorescent lamps, energy-saving bulbs, etc., and the high-intensity light sources that are more commonly used include high-pressure sodium lamps, complex metal lamps, and high-pressure mercury lamps. Among them, the complex metal lamp It belongs to high pressure φ gas discharge lamp (High Intensive Discharge; HID). It is added with a variety of metal compounds in order to emit light.

In this way, even if the lamps produced by different manufacturers have the same power, they cannot be started smoothly through the same trigger. ; On the other hand, even if the lamp and the trigger match, if the new lamp or the lamp is aging, different starting characteristics will be produced. Therefore, the general trigger design is based on the pulse width and pulse height required by the aging degree of the lamp to respond to the start of the high-pressure gas discharge lamp. Among them, the types of triggers produced by the trigger manufacturer can range from dozens of types to hundreds of times, so as to match the lamps of the lamp production plant. The current technology of juice triggers includes: high-pulse triggers (5 KV to 15KV high voltage is generally applied), multi-pulse triggers (generally 2 to 3 pulses are generated for each pulse shape), and high-frequency triggers (applied electronic High-frequency pulses are generated in the circuit), and I back-EMF triggers (high-voltage back-electromotive force generated by the application of electronic circuits) are used. However, among these methods, the replacement of the new lamp is likely to be caused by excessive voltage bombardment. Damage to its electrodes accelerates the aging of the lamp. Please refer to FIG. 1, which is a circuit diagram for explaining a conventional three-wire trigger. The three-wire trigger includes at least a voltage dividing capacitor C4, a discharge capacitor C5, a pulse generator 11, an autotransformer 12, and a Buffer 14. The pulse generator 11 is composed of a diode AC switch (DIAC, also known as a bidirectional trigger diode; BIAC). The working principle of the three-wire trigger is that the voltage-dividing capacitor C4 is

The surge voltage causes the pulse generator to generate a pulse voltage, which is input to one of the first-stage coils of the self-coupling dust converter 12 to read through the second-stage coil L4 of one of the white-coupling transformers 12 The pulse voltage is increased by -5 and input to a high-pressure gas discharge lamp 13 so that a trigger is generated between the gas elements (none shown) filled in the lamp f ^ and the discharge frequency of the discharge capacitor C5 is turned on. And the characteristics of the pulse generator are also fixed. Therefore, it cannot respond to: = the characteristics of the trigger pulse, the starting operation cannot be smooth.

However, the long-term failure of the lamp causes damage to the buffer 14 and loses the effectiveness of the protection system, thus reducing the conduction.

[Objective and Summary of the Invention] In view of the shortcomings of the conventional technology described above, the main object of the present invention is to provide an electric light trigger device that can be used with various high-pressure gas discharge lamps, and can not respond to the lamps.

As shown in FIG. 3, the electric light trigger device 2 includes a level controller 20, a dual pulse generator 21, a pulse intensity modulator 22, a self-resolving transformer 23, and an isolator. 24. Among them, the dual-acting pulse generator 21 is composed of the first and first DIACs (SD1, SD2) connected in parallel; the isolator 24 is composed of two diodes (D1, D2) connected in parallel with opposite poles. . $ 特 高 ^ (L wheel into the electric capacitor pole body (t far greater% is used to teach the capacitor will not be in a flat state & the controller integral speed $ (please enter the lamp pressure input with 'N) respectively through C3, Dl D2) Discharges C3 and II are generated in the shunt current and the ^ -pole body, so 20 will be used with a degree of 'dipolar capacity' to state 1 3 in the initial state to turn on the lamp, such as level control, and then connect it through it. The container C2, (Dl, D2 pulses, this pole body (D1 shunts the capacitor to determine the body (D1, the state is generally in a cold state, so it needs to be turned on by 1 3).

Invent Peng Ming (8) D2) At the same time as forming a loop state, the capacitor C1 of the pulse intensity modulator 22 starts to charge (that is, the integration operation), and when the charging voltage of the capacitor C1 is high When the first and second DIACs (SD1, SD2) are turned on, the first and second DIACs (SD1, SD2) will generate a breakdown voltage and input it to the capacitor C1, and the capacitor C1 will receive the The input voltage is transmitted to the first-stage coil L1 in the autotransformer 23. It should be noted here that the number of inductive turns of the first-stage coil L1 and the second-stage coil L2 of the auto-transformer 23 in this embodiment. The ratio is equal to the step-up ratio, and the ratio between the two is 1:18. Therefore, thousands of volts of standby voltage will be generated at the second-stage coil L2 and the terminal 13 Lp of the lamp tube 13 to turn on the lamp tube 13. When the lamp is successfully started, the lamp $ 13 is reduced to less than 200 volts (actually depends on the different lamps, about 100 volts to 200 volts). At this time, the bus current passes through the The lamp tube 13 constitutes a loop. In addition to stopping the capacitor C1 from integrating, the dual-actuator pulse generator 21, the level controller 20, and the isolator 24 are all in a level state, that is, the electric lamp. The triggering device stops the triggering work and completes the failing work of the lamp 13. In addition, since the first DIAC (SD1) or the second DIAC (SD2) is turned on, the balancing capacitor C3 will obtain an excessive charge supply, so it can act as a discharge capacitor, thereby making the first 1) 4 (; (81 ) 1) or the second DIAC (SD2) owner collapses the voltage and inputs the resulting pulse voltage into the miscellaneous capacitor C1, so that another trigger pulse will be input to the first-stage coil L1 of the autotransformer 23 in.

Therefore, the voltage obtained by the capacitor C1 for integration can be calculated, and the pulse width is wide. It is not very helpful for the original two sons to be excited, but for the ionized bar of the atom ^ y phase field dish, the number of left atom is greatly increased, the lamp tube 3 required ^ The ignition potential will be significantly reduced, this kind of pulse, the startup of the lamp tube Non-food is important.

When the pulse voltage generated by the invention (SD) (SD2) enters the capacitor Cl, an accumulation phenomenon occurs, thus forming 240 volts than the first DIAC (SD1) or the second DIAC (SD2) The higher voltage value is input to the first-stage coil u. Instead, please refer to the pulse waveform A3 shown in FIG. 4 (C). The pulse waveform A3 has a part larger than 2000 volts and a part smaller than 3 500 volts. It can be seen that when the first DIAC ( When the pulse voltage generated by SD1) or the second DIAC (SD2) enters the capacitor C1, the pulse voltage is attenuated by the capacitor and input to the first-stage coil L1.
