How to realize dimming of dimming led tube

The development of led lamps currently has many functions, one of which is dimming. The realization of this function can change the way of lighting, such as changing the scene lighting, making the lighting more flexible and warm, and from the perspective of energy saving, it is more cost-effective. So how does it dim?

There are many dimming methods at present

1. TRIAC dimming, this is one of the most common dimming methods. The thyristor dimming method usually only needs to replace the original power switch with a thyristor dimming switch when in use. The knob of the dimmer to achieve different brightness. The advantages of this dimming method are simple and practical, and the overall installation cost is relatively low, and only a thyristor dimmer needs to be added. It must be noted that the dimming can only be achieved by purchasing the corresponding dimming led tube. Ordinary LED tubes do not have this function. It should also be noted that the general dimmer switch has power requirements and cannot exceed its total power, otherwise it will be easily damaged.

2. Ordinary switch dimming is dimming through the power switch of the original lamp. There is no need to add any dimmer during installation. As long as the number and speed of pressing the original power switch are constantly pressed, the lighting can be adjusted. Light to meet the different brightness of individual needs. This kind of dimming method is relatively low-cost among all dimming methods. It can be used normally by replacing with a corresponding dimming LED tube when selecting it, and there is no need for line changes and additional installation costs. The dimming principle is that the brightness of the dimming led tube changes by 25% every time it is turned on or off. The brightness change sequence is 100% on-75%-50%-25%-off. Also note that you need to buy a lamp with the corresponding dimming function. This kind of lamp is called a three-stage dimming led lamp. Therefore, when purchasing an led tube, you must explain the function of the tube, otherwise you cannot use it when you buy it. This is very important.
