Description
技术领域 technical field
本实用新型涉及调光器领域技术，尤其是指一种可适合多种类型灯具进行调控之继电器并联控制的可控硅调光器。The utility model relates to the technology in the field of dimmers, in particular to a thyristor dimmer which is controlled in parallel by relays and is suitable for regulation and control of various types of lamps.
背景技术 Background technique
调光器是一种用来改变照明装置中光源的光通量、调节照度水平的电气装置，它的基本原理是改变输入光源的电流有效值以达到调光的目的。调光器按其控制方式可以分为电阻调光器、调压调光器、磁放大电抗调光器和电子调光器。A dimmer is an electrical device used to change the luminous flux of the light source in the lighting device and adjust the illuminance level. Its basic principle is to change the effective value of the current input to the light source to achieve the purpose of dimming. Dimmers can be divided into resistance dimmers, voltage dimmers, magnetic amplified reactance dimmers and electronic dimmers according to their control methods.
目前，公知之可控硅调光器是前述电子调光器的一种，其由可控硅、电感线圈及输入/输出接口端串联组成。可控硅作为调控元件，在电压过零后任一时刻均可触发导通，当通过可控硅的电流过零并且没有触发信号的前提下则可控硅将自动关断。因此，利用可控硅这一特性，可控硅接入正弦波交流电，当正弦波交流电过零后的某一时刻，在可控硅控制极上加一触发脉冲，使可控硅导通。从可控硅输出的电流，再通过电感线圈来增加负载电流的上升时间以减少电磁干扰，从而实现对各类型灯具进行控制。At present, the known thyristor dimmer is one of the above-mentioned electronic dimmers, which is composed of a thyristor, an inductance coil, and an input/output interface connected in series. As a control element, the thyristor can be triggered to conduct at any time after the voltage crosses zero. When the current passing through the thyristor crosses zero and there is no trigger signal, the thyristor will automatically turn off. Therefore, using the characteristic of the thyristor, the thyristor is connected to the sine wave alternating current, and at a certain moment after the sine wave alternating current crosses zero, a trigger pulse is added to the control electrode of the thyristor to turn on the thyristor. The current output from the thyristor is then passed through the inductance coil to increase the rise time of the load current to reduce electromagnetic interference, thereby realizing the control of various types of lamps.
然而，当输出端负载为气体放电灯具时，如果可控硅内部其中一个晶闸管损坏时，输出电流变为直流，将导致气体放电灯的镇流器损坏。However, when the load at the output end is a gas discharge lamp, if one of the thyristors inside the thyristor is damaged, the output current becomes DC, which will cause damage to the ballast of the gas discharge lamp.
