The development of LED lamp has many functions, one of which is dimming function. The realization of this function can change the lighting method, such as changing the scene lighting, which makes the lighting more sensitive and warm, and more cost-effective from the perspective of energy saving. So how is it dimming?

Now there are two dimming methods

The first is the common low-voltage dimming, which is dimming through a voltage of 0-10V. The method is that the main power supply gathers power and controls multiple LED tubes for dimming. The advantage is that the LED tubes are simple and do not need to be built-in. Generally, 12 light beads are used to supply 36V power supply. 36V power supply generally adopts switching power supply with constant voltage function.

The second is thyristor dimming, the most common dimming method. Thyristor dimming only needs to replace the power switch with thyristor dimming switch. The brightness can be adjusted by adjusting the knob of the dimmer to meet the requirements of different illuminance, and its brightness can be adjusted continuously by 0-100%. The advantage of this dimming method is simple and useful. Only one thyristor dimmer needs to be replaced. The power of common panel thyristor dimmer switch is 200W, and the device size is the same. There is also a 1-2kw dimmer. It must be noted that dimming can only be realized by purchasing corresponding dimming LED tubes. General LED tubes do not have this function. It should also be noted that the general dimming switch has power requirements and cannot exceed its total power, otherwise it is easy to be damaged.

The third kind of general switch dimming is dimming through the power switch. There is no need to add any dimmer. Just press the power switch repeatedly, and the dimming of the lighting LED tube can be reached through the number of switches. To achieve the required brightness. This dimming method has low cost. When it is selected, it can be used normally only by changing a corresponding dimming LED lamp without circuit change and increasing any cost. The dimming principle is that the brightness of dimming LED tube changes by 25% every time it is turned on and off. The brightness change order is 100% on - 75% - 50% - 25% - off. We should also pay attention to the purchase o f lamps with corresponding dimming functions. This kind of lamp is called three-stage dimming LED lamp. Therefore, when buying LED tubes, you must clarify the functions of the tubes, otherwise you can' t use them when you buy them. This is very crucial.
