The first light dimmer switch is invented in the year of 1890. Early light dimmer is a large plate directly controlled by manual operation. There are inconvenience and potential risk especially when the system has a large number of channels. According to the control mode and the application field, lights dimmer can be classified into different types. According to the control mode, light dimmer can be classified into resistance dimmers, regulating dimmers, magnetic amplifier reactance dimmers and electronic lights dimmers. According to using occasions, light dimmers can be classified into civilian light dimmers, stage lights dimmer, airport lighting dimmers and daylight integrated control system. Here I am going to give a brief introduction on some of them.

1. Resistance dimmer. Concatenate a resistor in the middle of an incandescent light source and power supply. We can change the resistance value of the current source to achieve dimming purposes. AC and DC power supply can both be used and there is no radio interference if we use resistance light dimmer.

2. Stage dimmable LED driver. There are two types of stage lights dimmer. They are single loop and multi-loop stage light dimmer and each circuit has larger capacity. Multi-loop and large capacity constitutes a system which is known as the dimming device. Control methods are manual control and computer control. According to different sessions and times, the brightness information can be set previously in the computer. According to the special requirements on stage lighting, there has been the emergence of new varieties of tone control and dimmer control programs.

3. Daylight integrated control system. It is a kind of automatically adjustable optical-intensity system with microcomputer system. It is usually used in many offices. The centralized control is related to the indoor work time schedule to achieve the goal of unattended operation and save power. It uses the photoelectric control, time program and computer technology to make the LED controller reaching the required level. The system includes daylight dimming, time sequence control and alarm control dimming. Most of the light dimmers load for incandescent lamp, a few for fluorescent lamp.
