Description

Be used to control the circuit arrangement of illuminating lamp voltage

Technical field:

The utility model relates to a kind of circuit arrangement that is used to control illuminating lamp voltage.

Background technology:

According to statistics, the electric weight of China's illuminating lamp waste at present is equivalent to the generated energy of three Ge Zhou Bas, so, reduce the energy consumption of illuminating lamp, its meaning and not second to building the generated energy that the Ge Zhou Ba obtains.The voltage of exporting owing to power supply network can reduce along with the increase of consumer use amount, it is the use amount that the output voltage of power supply network is controlled by consumer, in the ordinary course of things, in order to prevent consumer fail to start under the lower situation of line voltage, its output voltage will be higher than ratings, and is random variation.Yet the voltage of this variation can bring the influence of two aspects to illuminating lamp: waste electric energy when an aspect is overtension, and build-up of luminance not during brownout; Another aspect is the serviceable life that the voltage of fluctuation can shorten illuminating lamp.

In the prior art, reduce the energy consumption of illuminating lamp and mainly take two approach, the one, the low illumination effect of employing power consumption is 5 times a new light sources with the capacity illuminating lamp, but its price is higher, and existing also do not have large tracts of land to promote the use of; Another approach is to want to cut down the consumption of energy by the mode that reduces the illuminating lamp input voltage, as adopting controllable silicon and transformer step-down.Though controllable silicon can be adjusted economize on electricity continuously and press,, because of controllable silicon can produce a large amount of harmonic waves in the pressure regulation process, not only electrical network is polluted, but also the serviceable life that can reduce illuminating lamp; And adopting the transformer step-down, its output voltage also can fluctuate along with the fluctuation of line voltage.

For this reason, the name of No. 2751507 Granted publications of Chinese patent is called " illuminating energy-saving voltage stabilizing control device " and provides a solution.This patent adopts two powerful transformers, control two powerful transformers by 6 contactors, and the input end of each contactor is controlled by a relay respectively.Though this device can be energy-conservation to realize for the lower voltage of illuminating lamp input, but, because contactor and relay all are touch switch parts, and the touch switch parts can send dry sound at work, and serviceable life is shorter relatively, simultaneously also need to consume a part of electric energy, so the control device of this kind structure awaits further to improve.

Summary of the invention:

Task of the present utility model provides a kind of mode of utilizing contactless control and solves power consumption and noise, and serviceable life etc. problem the circuit arrangement that is used to control illuminating lamp voltage.

The circuit arrangement that the utility model proposed is used to control illuminating lamp voltage comprises the transformer device that is installed in the housing and the non-contact type switch block that is electrically connected with lead terminal that the input end of this transformer device is drawn, and the pulsed trigger element that is used to control the conducting of non-contact type switch block or ends.

Described transformer device comprises the transformer of two polyphones, one of them transformer elementary is provided with at least two lead terminals, and be electrically connected with a contactless switch block on the lead terminal respectively, and be connected with two and the non-contact type switch block that connects on the elementary terminal of another transformer.Described non-contact type switch block is made of thyristor or bidirectional thyristor.

Described pulsed trigger element comprises a single-chip microcomputer and by this monolithic processor controlled pulse signal generation device, this pulse signal generation device has and the corresponding triggering output terminal of the quantity of non-contact type switch block.

The non-contact type switch block that the circuit arrangement employing that the utility model proposed is made of thyristor or bidirectional thyristor comes the output voltage of control transformer, so, can not make a noise in this device busy, and serviceable life is longer; Simultaneously, this installs gradable adjusting output voltage, thereby reaches economize on electricity; In addition, because the non-contact type switch block is selected relatively low thyristor of cost or bidirectional thyristor for use, so this device can reduce cost of manufacture.

Accompanying drawing 1 is the circuit theory diagrams of the circuit arrangement that proposes of the utility model;

Accompanying drawing 2 is circuit theory diagrams of pulsed trigger element.

Embodiment:

Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide that the utility model proposes is used to control the circuit theory diagrams of an embodiment of circuit arrangement of illuminating lamp voltage.As can be seen from the figure, this device comprises transformer device and non-contact type switch block, and these three parts of pulsed trigger element.What propose in the present embodiment that the non-contact type switch block selects for use is bidirectional thyristor.

Transformer device comprises the transformer T1 and the T2 of two polyphones, and source current is held through transformer T1 and T2 by A, and load RL to N end flows out.Transformer T1 elementary has four lead terminal B, C, D, E, wherein, lead terminal B is electrically connected with two opposite polarity bidirectional thyristor KS1, KS2, and lead terminal C and D are electrically connected with a bidirectional thyristor KS3 and KS4 respectively, and lead terminal E directly is connected with the N end of power supply; And elementary two opposite polarity bidirectional thyristor KS5 and the KS6 of being provided with of transformer T2, and the input end of bidirectional thyristor KS5 is connected with the A end of power supply, the input end of bidirectional thyristor KS6 is connected with the N of power supply end.

The pulsed trigger element comprises a single-chip microprocessor MCU and the pulse signal generation device MSU that is controlled by this single-chip microprocessor MCU, this pulse signal generation device MSU can adopt the silicon controlled toggle of KC04 type, and makes it have six lead-out terminal K1, K2, K 3, K4, K5, K6 that are used to trigger bidirectional thyristor.Conversion detects and exports control signal to pulse signal generation device MSU to single-chip microprocessor MCU to main power voltage, send control signal by pulse signal generation device MSU to bidirectional thyristor again, be that K1, K2, K3, K4 in the pulse signal generation device MSU output terminal is the instrument that is respectively applied for control bidirectional thyristor KS1, KS2, KS3, KS4 trigger angle, and bidirectional thyristor KS1, KS2, KS3, KS4 have only one of them bidirectional thyristor conducting when work.And K5, the K6 of pulse signal generation device MSU output terminal are the instruments that is respectively applied for control bidirectional thyristor KS5 and KS6 trigger angle, and bidirectional thyristor KS5, KS6 can only have a conducting equally.

To have only bidirectional thyristor KS1 conducting, the fixed voltage of the secondary output of transformer T1 is set at the X volt, and following two kinds of operating modes can appear in this device:
