Abstract
The utility model relates to a silicon controlled rectifier (SCR) dimmer with relays controlled in parallel, comprising SCR, a relay, an inductance coil and a control panel. The SCR is connected with the relay in parallel; the control grid of the SCR and a coil end of the relay are respectively connected with the control panel, the control panel can effectively choose the SCR or the relay to work so as to realize the regulation of various lighting fixtures. For example, when the lighting fixture is non-gas discharge lighting fixture, by controlling a control closed relay of the control panel, the lighting fixture can be regulated by SCR; when the lighting fixture is gas discharge lighting fixture, the relay is working by controlling the SCR of the control panel; gas discharge lighting fixture is regulated to avoid that the output electric current turns into DC when a thyristor in the SCR is broken, thereby leading the damage of a ballast of the gas discharge lighting fixture, thus overcoming the shortages in prior art and realizing effective protection to the gas discharge lighting fixture.
Description
Technical field
The utility model relates to the dimmer art, refers in particular to a kind of controllable silicon dimmer that is fit to the relay Parallel Control that the polytype light fixture regulates and control.
Background technology
Dimmer is a kind of be used for the changing luminous flux of light source in the lighting device, electric device of adjusting illumination level, and its basic principle is to change the current effective value of input light source to reach the purpose of light modulation.Dimmer can be divided into resistance dimmer, voltage-control dimming device, magnetic amplification reactance dimmer and electronic light modulator by its control mode.
At present, known controllable silicon dimmer is a kind of of aforementioned electronic dimmer, and it is composed in series by controllable silicon, inductance coil and input/output interface end.Controllable silicon is as controlling element, but in voltage zero-cross successor one equal triggering and conducting constantly, when by the silicon controlled current over-zero and there is not the next controllable silicon of prerequisite of triggering signal to automatically shut down.Therefore, utilize this characteristic of controllable silicon, controllable silicon inserts sine wave alternating current, a certain moment after the sine wave alternating current zero passage, add a trigger impulse in SCR control on extremely, and make the controllable silicon conducting.From the electric current of controllable silicon output, the rise time that increases load current by inductance coil to be reducing electromagnetic interference again, thereby realizes all types of light fixtures are controlled.
Yet when the output load was the gas discharge light fixture, if when inner one of them thyristor of controllable silicon damages, output current became direct current, will cause the ballast of gaseous discharge lamp to damage.
The utility model content
The utility model is at the disappearance of prior art existence, and main purpose provides a kind of controllable silicon dimmer of relay Parallel Control, and it can realize that the polytype light fixture regulates and control.
For achieving the above object, the utility model adopts following technical scheme:
A kind of controllable silicon dimmer of relay Parallel Control, comprise controllable silicon, relay, inductance coil and control panel, this controllable silicon is in parallel with relay, its input inserts sine wave alternating current, and output is connected with inductance coil, and this inductance coil connects output interface, provides load to connect by this output interface; The coil-end of the above-mentioned silicon controlled control utmost point and relay is connected respectively on the control panel, and this control panel is used for receiving and handling external control signal, selects controllable silicon or relay work to control different loads by control panel and regulates and control.
Above-mentioned load comprises gas discharge light fixture or non-pneumatic Discharging lamps and lanterns.
The utility model compared with prior art, its beneficial effect is: the relay in parallel at the controllable silicon two ends, select controllable silicon or relay work effectively by control panel then, realize that the polytype light fixture regulates and control.For example, when light fixture is the non-pneumatic Discharging lamps and lanterns, controllable silicon can be regulated and control to light fixture by the control closed relay of control panel; When light fixture is the gas discharge light fixture; close controllable silicon and only make relay carry out work by the control of control panel; the gas discharge light fixture is regulated and control; when avoiding because of one of them thyristor damage of controllable silicon inside; output current becomes direct current; cause the ballast of gaseous discharge lamp to damage, overcome the deficiency of prior art, realize effective protection of gas discharge light fixture.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Show the circuit structure of the embodiment of the utility model with reference to Fig. 1, as seen from the figure, comprise controllable silicon V, relay J, inductance coil L1 and control panel, this controllable silicon V is in parallel with relay J, its input inserts sine wave alternating current, and output is connected with inductance coil L1, and this inductance coil L1 connection output interface, provides load light fixture A to connect by this output interface; The control utmost point of above-mentioned controllable silicon V and the coil-end of relay J are connected respectively on the control panel, and this control panel is used for receiving and handling external control signal, select controllable silicon V or relay J work to control different light fixture loads by control panel and regulate and control.
Operation principle of the present utility model is as follows:
Control panel inserts power supply and starts working, and receives and handle the control signal from the outside, and controllable silicon or relay is sent instruction control.
When light fixture A is the non-pneumatic Discharging lamps and lanterns, by the control closed relay J of control panel controllable silicon V can be regulated and control to light fixture A, electric current was flowed through and was flowed into inductance coil L1 behind the controllable silicon V this moment, flow through light fixture A again, the rise time that inductance coil L1 is used for increasing load current is so realized the control to light fixture A to reduce electromagnetic interference.
When light fixture A is the gas discharge light fixture, close controllable silicon V and only make relay J carry out work by the control of control panel, electric current was flowed through and was flowed into inductance coil L1 after the relay J this moment, flow through light fixture A again, the rise time that same inductance coil L1 is used for increasing load current is realized the control to light fixture A to reduce electromagnetic interference.
Of the present utility model focusing on: the relay in parallel at the controllable silicon two ends, select controllable silicon or relay work effectively by control panel then, realization polytype light fixture is regulated and control.For example, when light fixture is the non-pneumatic Discharging lamps and lanterns, controllable silicon can be regulated and control to light fixture by the control closed relay of control panel; When light fixture is the gas discharge light fixture; close controllable silicon and only make relay carry out work by the control of control panel; the gas discharge light fixture is regulated and control; when avoiding because of one of them thyristor damage of controllable silicon inside; output current becomes direct current; cause the ballast of gaseous discharge lamp to damage, overcome the deficiency of prior art, realize effective protection of gas discharge light fixture.
