Non-dimming and dimming lights classification and control

Non-dimming light classification and control

1) The so-called adjustable light means that the brightness of the light can be adjusted, that is, the brightness of the light can be adjusted to any value from 0% to 100%. As the name suggests, non-dimmable is the light intensity of the light can not be adjusted, that is, the brightness of the light is either 0%, or 100%.

2) Fluorescent lamps are non-dimmable lamps commonly used in daily life. Traditional fluorescent lamps, namely low-pressure mercury lamps, use the low-pressure mercury vapor to release ultraviolet rays after being energized, so that the phosphor emits visible light, and therefore it belongs to low pressure. Arc discharge light source. The electrodeless fluorescent lamp is an electrodeless lamp. It eliminates the filaments and electrodes of conventional fluorescent lamps and uses the principle of electromagnetic coupling to excite the mercury atoms from the original state to the excited state. Its light emission principle is similar to that of a conventional fluorescent lamp, and has a long life and high light efficiency. Good color rendering and other advantages. Common fluorescent lamps include straight-tube fluorescent lamps, colored straight-tube fluorescent lamps, circular fluorescent lamps, and single-ended compact fluorescent lamps.

There are two common control methods for non-dimmable lamps: one method is manual control through a non-dimmer switch (non-dimming mechanical switch); one method is through a smart home control software, using a smart terminal such as a PAD, a mobile phone, etc. Smart control (wireless touch switch).

There are also many types of non-dimmable lamps. Here, only fluorescent lamps are used as examples. Others are not listed one by one.

Dimming light classification and control

Incandescent lamps and metal halide lamps are widely used in dimming applications. However, with the continuous promotion of energy-saving and emission-reduction policies, LED dimmable light has begun to show development trends after it overcomes the dimming technical difficulties.

There are many methods for classifying metal halide lamps, which can be divided into four types according to the fillers: Sodium Indium, Indium, Strontium, and Halides.

According to the structure of the lights can be divided into 3 categories:

1 The quartz arc tube contains two main electrodes and one starting electrode, and a metal halide lamp with a rigid glass bulb (with straight tube shape and ellipsoid shape) is installed on the outside;

2 Straight tube-shaped arc tube is equipped with a pair of electrodes, without external glass bulb, instead of straight tube metal halide lamp, used for flood lighting in stadiums and other areas;

3 Short-arc spherical metal halide lamps, single-ended or double-ended ellipsoidal metal halide lamps without outer bulbs.

There are two common control methods for the dimming lamp: One method is to control through a dimming switch; the other method is to use a smart home control software to intelligently control using a smart terminal such as a PAD or a mobile phone.

With the improvement of living standards, people are inseparable from light, but also can not do without the requirements of the quality of light. Dimming needs can be roughly divided into the following three categories:

1) The need for functional light adjustments, such as entrances, meeting rooms, etc.

2) The expression of comfort and life style in home life, such as the matching of light and darkness of the lighting, and the warm and cold color temperature, which can be adjusted according to the needs of the environment, and can also play a role in the atmosphere.

3) The need for environmental protection and energy conservation, such as energy-saving needs in public places, parking lot lighting, shopping mall lighting, road lighting, etc. The dimmer switch can meet people's different requirements for light brightness at different times, and can directly replace the existing wall switch, and is suitable for family rooms, apartments, hotels, hospitals and other public places.
