Principle of automatic light-filling LED fluorescent tube
The latest product of Benwei company-automatic light-filling led fluorescent tube, the alias of automatic light-filling led fluorescent tube is also called dimming led tube, light control led tube, light induction led tube, the main purpose is to realize the control of led light by natural light Tube brightness, realize automatic fill light.
Usually LED fluorescent lamps are controlled by switches, either directly on or off, or dimming, or inductive dimming. These LED tubes are not as convenient as LED fluorescent tubes that automatically fill light.
Working principle of automatic light-filling LED fluorescent tube
1. When the light is strong, the brightness of the auto-filled LED fluorescent tube will be reduced, and this dimming is continuous
2. When the ambient light is weakened, the brightness of the auto-filled LED fluorescent tube will gradually increase, and the light intensity will also be continuous
3. Of course, when not in use, there is a switch that can be turned off directly
How is the automatic fill light LED fluorescent tube realized?
Utilize the light-sensitive original to the light, adopt the principle of light control to directly control the power supply of the led tube to realize constant current regulation. Commonly used control methods are: regulation of voltage and regulation of current.
When the ambient brightness is lower than the required illuminance, the LED fill light tube will automatically start to work, on the contrary, it will automatically turn off, fully realizing automatic continuous dimming, so that the ambient light illuminance is always in a reasonable and comfortable state.
The LED supplemental light tube relies on a small current to drive semiconductor devices to emit light. It is an environmentally friendly product with low energy consumption and high brightness, and can be used in many occasions. For example, it is used to fill light when the light is insufficient. Home interior lighting, office lighting, night landscape background color lighting, road or street night lighting, as well as various silver screen backlight fill light, not only shooting photos, etc.
The led fill light tube is generally used to increase the lack of light on the front of the object and use a light supplement method. Suitable for large area automatic fill light
