Abstract
The utility model discloses a device which adopts the AC power and controllable silicon for light adjustment control. The model consists of an adjustment table, a silicon box and a lamp. Every control silicon circuit includes a bidirectional silicon in a silicon box, the equipment can generate independently controlled and reverse and forward alternate current pulse sequence under the action of two control pulses and are connected to two channels of independent lamps via reverse parallel connection, so a control circuit can control the brightness change of two channels of lamps. Therefore, the circuit device is high in utilization rate, overcomes the bugs of current technology such as using a plurality of electronic parts and cables and high installation cost.
Description
The utility model relates to a kind of places such as stage, television stadio, arenas theater that are used for and adopts AC power and controllable silicon to carry out the device of brightness adjustment control.
The existing light modulation equipment that is used for places such as stage, television stadio, arenas theater generally changes the silicon case that the brightness adjustment control silicon road of controlled alternating current is combined into into by the weak electric signal that provides the Control Console that sends light control luminance signal, Control Console is sent and is constituted.It is on all four that the lamp brightness of each controllable silicon control that the loop connects changes, having different brightness just need be connected to different controllable silicon loops gets on, therefore this device needs numerous controllable silicon loops could form the lighting environment of satisfying the demand, therefore each silicon road can not be fully utilized, the whole system serious waste of resources, and it is many to have stube cable, defectives such as installation cost height.
The purpose of this utility model just is to provide a kind of light modulating device that can improve system resource utilization efficient.
The purpose of this utility model is achieved in that it is made up of Control Console, silicon case and light fixture.Each control silicon road adopts bidirectional triode thyristor to form in the silicon case, and two input is accepted two signals outputs of Control Console, and the output on control silicon road links to each other with the diode of reverse parallel connection, each diode again with one the tunnel independently light fixture be connected.Silicon road in the said apparatus can produce the forward and two kinds of different current pulse sequence that oppositely replace of independent control under two control signal effects, two kinds of current pulse sequence are by the diode of reverse parallel connection, lead on the two independent light fixture respectively, a road lighting lantern wherein receives the forward current pulse, and another road lighting lantern reception is reverse current pulses.Because what each road lighting lantern received all is the unidirectional pulse electric current, therefore one road controllable silicon can independently be controlled two-way light.
The bidirectional triode thyristor that use on control silicon road can be replaced by a pair of controllable silicon that is reversed parallel connection, and each silicon controlled input is accepted a signal output of Control Console, the current pulse sequence that produces forward and oppositely replace.
The utility model with prior art relatively, the technical scheme that it adopts can make each the silicon road in the silicon case that two independently brightness adjustment control passages are provided, under the constant situation of silicon road total amount, can provide brightness to change the more lighting environment of horn of plenty, can also dynamically reduce simultaneously the way of silicon according to the situation at scene, therefore cost of use, installation cost, cable consumption are all reduced accordingly, and provide an approach easily for the transformation of outmoded light modulation equipment.
By the following examples and in conjunction with the accompanying drawings the utility model is further described.
Fig. 1 is the structural representation of device.
Silicon case 2 among Fig. 1 has trigger module 3 and several control silicon roads 4, and trigger module 3 makes dim signal convert the trigger impulse on corresponding control silicon road 4 to, controls silicon road 4 by two oppositely parallel controllable silicons 5,6 that connect, coil 7, and circuit breaker 8 is formed.Two kinds of luminance signals of Control Console 1 output are transported in the trigger module 3, two kinds of two kinds of trigger impulses that luminance signal produced are input to the controllable silicon of controlling in the silicon road 45,6 input, make a control silicon road 4 produce the forward and two kinds of different current pulse sequence that oppositely replace of independent control, two kinds of current pulse sequence are input to the diode 9 of reverse parallel connection, 10, diode 9,10 outputs are communicated with one tunnel light fixture 11 independently respectively, 12, a road lighting lantern 11 wherein receives only the forward current pulse, and another road lighting lantern 12 receives is reverse current pulses, and therefore one road controllable silicon can independently be controlled two-way light.
