Description

A kind of controllable silicon dimmer equipment based on KNX buses

Technical field

The utility model is related to the light modulation field of lighting system, more particularly, to a kind of thyristor regulating based on KNX buses Light device equipment.

Background technology

In the illumination system, light modulation is critically important.A more comfortable environment is obtained between two parties not only for being in, For today, unnecessary light is reduced, is important something with the purpose for further realizing energy-saving and emission-reduction.It is and right For LED light source, light modulation is also to be easier to realize than other fluorescent lamps, energy-saving lamp, high-pressure sodium lamp etc., so more should be each Plus the function of light modulation in the LED lamp of type.Light modulation is a general orientation of LED actuation techniques development, in technology realization There are silicon-controlled and two kinds of dimming modes of PWM.It is silicon-controlled that advantage is had much in alternative, and PWM more meets people and LED is dimmed The requirement of precision, efficiency and effect.Difference based on principle, the two have different design considerations.

A kind of dimming mode that thyristor regulating is just generally used in incandescent lamp and energy-saving lamp application at present.Its work It is that the output voltage waveforms of certain angle of flow are generated after the waveform of input voltage is cut wave by the angle of flow as principle. Using the principle of the angle of flow, the virtual value of output voltage can be reduced, the power of normal load (ohmic load) is reduced with this.It can The advantages of control silicon light modulation, is that working efficiency is higher, and performance is stablized.But based on its operation principle, in application, there is also some Design defect, having its source in after controlled silicon conducting for defect need one electric current is maintained to be held on, otherwise can be restored to and cut Only state.Different silicon-controlled maintenance electric currents is different, and usually in several mA between tens mA, some is even up to 50mA.And work( Rate is bigger, and the maintenance electric current needed is bigger, if maintained, electric current is inadequate, and the angle of flow is unstable, and the waveform of output can not yet Uniformly, and trembling and spike can be generated, just will appear flicker when such unstable output is added on LED.Before Incandescent lamp is due to being linear load, and operating current all can be more than generally 50mA, so the phenomenon that being not in flicker, therefore LED product is not directly applied for suitable for the controllable silicon dimmer of incandescent lamp on the market at present, needs to be designed it improvement To meet the working characteristics of LED.

Market is there are also many silicon-controlled light modulators, but many light modulators are all independent manual local controls System, it is impossible to carry out long-range Background control and function is relatively simple.A part of equipment have the characteristics that it is intelligentized, using being incorporated to Light current power grid controls the mode of forceful electric power circuit, these equipment are based on RS485 or CAN bus networking carries out Background control, into This is relatively low, and comparing has price advantage, however, be RS485 or CAN bus, there is presently no unified bus protocol standard, Each producer is all to carry out networking to module using custom protocol, and the equipment of different manufacturers can not be general, and substitutability is not By force, once stopping producing by producer, equipment will cannot get post-sale support.In addition current also some equipment is in silicon-controlled base On plinth, using with international, uniquely suitable for family and the KNX agreements of building automation field open-standards, equipment can be big Scale networking, the KNX products of different manufacturers also have good interoperability.

By retrieval, China Patent Publication No. discloses a kind of indoor LED illumination brightness adjustment control dress for CN104853484B It puts and method, including intensity of illumination acquisition module, Synchronous signal acquisition module, signal processing and operation module, unit effect mould Block and remote control module.For the inadequate hommization of interior lighting system, intelligence and it is energy saving the problem of, microcontroller is used to match for core Share silicon-controlled controlled interior lighting system and the optimization design of technology.Light regulating technology is introduced interior lighting system, It by the comparison to a variety of LED light regulating technologies, selects to optimize controllable silicon light modulation technology, realizes the brightness control to LED light System.In order to realize specific control effect, the Acquisition Circuit of synchronizing signal and natural light intensity is designed.In view of traditional switch makes Inconvenience in is added to remote control module, and new function is developed in the module in design.But the utility model makes It is the control that IR remote controller carries out system, it is impossible to, can not can be by background client terminal with other equipment networking Row monitors and controls, and does not meet the requirement of era development.
