Description

LED dimming controller

Technical Field

The invention relates to the field of dimming controllers, in particular to an LED dimming controller.

Background

A dimmer is an electrical device that varies the luminous flux of a light source in a lighting device, adjusting the level of illumination. A large capacity and constituting a system is called a dimming device. The basic principle is to change the effective value of the current of the input light source to achieve the aim of dimming. The purpose of the dimmer is to adjust the light to different intensities. The different intensities of light output produced by the average power lamp light are encouraged by reducing or increasing the RMS voltage. While variable voltage devices can be used for various purposes, such regulation is intended to control lighting. The range of the dimmer is: the normal-sized light switch of a small unit is used for household lighting and large theaters or building lighting facilities used by high-power units. Small unit dimmers are typically controlled directly, while high power units employ remote control systems. Modern professional dimmers typically employ digital control systems like DMX or ethernet. Dimmers can be classified by control mode and application. The LED lamp can be divided into a resistance dimmer, a voltage-regulating dimmer, a magnetic amplification reactance dimmer and an electronic dimmer according to a control mode; the system is divided into a civil dimmer, a movie and stage dimmer, an airport light dimmer and a daylight comprehensive control system according to the use occasions. The resistance dimmer connects the resistance in series between the incandescent light source and the power supply, and the current in the light source can be adjusted by changing the resistance value, thereby achieving the purpose of dimming. Its advantages are high energy consumption, low efficiency, large size and inconvenient control. Can be used in the illumination of laboratories, electrified education demonstrations and ship navigation equipment. Voltage-regulating light modulator, an autotransformer. The secondary voltage is changed by adjusting the contact position of the brush with the coil wound outside the yoke of the transformer. The LED lamp has the advantages of low energy consumption, high efficiency and no influence on the original dimming degree due to the increase of the load within the rated power. The disadvantages are that the device is only suitable for AC power supply, heavy, consumes more colored and ferrous metal, and can not be controlled remotely. The magnetic amplifying reactance dimmer changes the inductive reactance of an alternating current winding by changing the current in a direct current winding wound on an iron yoke. It has good dimming performance and is convenient to control, but is bulky and heavy, and has been replaced by electronic dimmers. Electronic dimmers have early used thyristors as switching elements and later thyristors. The dimmer has the advantages of light weight, small volume, high efficiency, easy remote control and the like, and is widely used. It has the disadvantage that radio interference occurs without effective filtering measures and dimming is cumbersome for gas discharge light sources such as fluorescent lamps, high intensity gas discharge lamps, etc. Dimmers employing high power transistors or fets may overcome this disadvantage. . The existing LED dimming controller mostly uses a knob to adjust, and due to the fact that no corresponding protection structure exists, the LED dimming controller is easily touched by mistake in the actual using process, and then the light intensity of the LED lamp is changed unintentionally, and the normal use of the LED lamp is finally influenced.
