The utility model comprises a filtering capacitance (c-[1]), an inductance (l-[2]), a pulse capacitance (c-[2]), a silicon switch circuit (1), a pulse transformer (l-[3]) and a housing (2), a dysprosium lamp of the utility model is connected to a circuit, and when a power supply is opened, the dysprosium lamp can be kindled reliably according to the condition of the dysprosium lamp, thus ensuring that the dysprosium lamp tube can work safely. The utility model has the advantage of long service life.
Description
The utility model relates to a kind of starting switch circuit arrangement of lighting gas discharge lamp tube.Specifically, be a kind of electronic trigger of lighting dysprosium lamp.
Dysprosium lamp is the new gas discharge lamp of a kind of high light efficiency, high colour developing, and it is applicable to the illumination in places such as airport, harbour, station, square and construction site, is particularly suitable for the live television coverage illumination in entertainment, physical culture place.Yet, because dysprosium lamp when opening, must apply high voltage in lamp tube ends, just can excite gas discharge in the pipe, light fluorescent tube, in case and the fluorescent tube starting point, institute adds high pressure and should promptly disappear.Otherwise, influence lamp tube service life.For this reason, use the dysprosium lamp trigger, realize the trouble free service of dysprosium lamp.
Existing dysprosium lamp trigger all is to use the inductance oscillator, and the continuous vibration by oscillator makes the connecting and disconnecting constantly of its contact, thereby makes capacitor C on the LC loop by the oscillator contact, through the primary coil discharge of pulse transformer, through transformer " L
3" boosting produces high-voltage pulse and superpose with the power supply transient voltage and put on lamp tube ends, makes the dysprosium lamp starting point.After making the fluorescent tube starting point, just remove the high-voltage pulse that is applied, existing trigger has been adorned the connecting and disconnecting that a manual switch or the time relay are controlled inductance oscillator coil in addition, promptly control the switch in high-voltage pulse loop, be called switch control high-voltage pulse loop trigger and time relay control high-voltage pulse loop trigger.The shortcoming of above-mentioned two kinds of triggers is oscillator contacts because of the long-term oxidation deactivation that uses, and particularly uses the oscillator contact more fragile in occasion moist, the gas that is corrosive.In addition, the coil of the time relay also will stand impacting with high pressure and the qualitative reason of itself, often will damage, lose efficacy, thereby burn out the oscillator coil; More again, owing to the timing of the time relay can not arbitrarily be changed, and dysprosium lamp Guan Ze like this, in use for some time, just can not light fluorescent tube the long triggered time reliably because of aging the needs; It should be appreciated that,, increased the cost of trigger significantly owing to relay service time.For the trigger of switch control high tension loop, cost is lower, and can control the work in high-voltage pulse loop at any time,, just inconvenient in the occasion operation of a plurality of dysprosium lamp illuminations, particularly when coliseum uses, every dysprosium lamp all will be provided with a cover control loop, and expense is risen.
The purpose of this utility model provides that a kind of cost is low, simple structure, and can trigger the electronic trigger of starting point dysprosium lamp automatically.
The utility model is to implement like this: adopt the reverse-blocking tetrode thyristor circuit to substitute the contact of the inductance oscillator in the existing dysprosium lamp trigger, thereby, can save the manual switch or the time relay and reach to produce automatically and trigger the starting point high-voltage pulse according to the working condition of dysprosium lamp.Be that the utility model is by filter capacitor " C
1", inductance " L
2", pulsed capacitance " C
2", reverse-blocking tetrode thyristor circuit " 1 ", pulse transformer " L
3" and support and insulation crust " 2 " composition, And has three external connection ports " A ", " B " and " C ".The utility model is inserted behind the dysprosium lamp circuit because the silicon controlled switching characteristic can realize triggering automatically starting point according to the working condition of dysprosium lamp.
The utility model has the advantages that: 1. owing to save the time relay, greatly reduce cost and improved the reliability that the triggering dysprosium lamp is lighted; 2. owing to do not use the contact of inductance oscillator, avoided being suitable for using under the various environmental conditions because of caused faults such as contact oxidation, corrosion; 3. the utility model useful life is long-life dysprosium lamp trigger more than the prior art height.
