The working principle of three kinds of 1.2m induction led tube
Benwei 1.2m induction led tube is completely independent research and development, high stability, no false trigger, sensitive response, accurate delay, and small error. In particular, the isolation-type outlet 1.2m induction led tube has passed CE and tested the electromagnetic compatibility index EN5510, which has been well received by customers.
1. The principle of induction 1.2m led tube:
1. Principle of infrared induction led tube: using Fresnel lens, multilateral. When an electromagnetic wave with a specific infrared wavelength is sensed by the lens, for example, it is counted as A, and a waveform is reflected at the same time, which is counted as B. The two will produce a waveform difference, that is, AB=C, then this C value will make the infrared pyrosensor directly sense this variable and produce a current change. This current change will trigger the chip to work, so as to control the power supply. jobs. For example, when the delay is over, let the led tube work again.
2. Radar induction led tube: There is also a principle called microwave induction: the radar model exists in the form of microwave, with an extremely short wavelength, and its wavelength is lower than visible light and lower than infrared. From the perspective of wave-particle binomial, it belongs to particle nature, with a certain amount of energy, and a certain degree of penetration and reflection. Based on this feature, it is widely used in a variety of industries, such as radar, missile, distance detection, etc. The principle is: when the radar antenna emits radar waves, that is, microwaves, the microwaves will be reflected back when they meet the object. At this time, the antenna will collect the microwaves, which will also produce a difference, relying on this small change to control The CPU is the central processing unit of the computer, allowing the power supply to work. The led tube can also be controlled to work as required.
3. The working principle of the sound-controlled induction led tube: sound waves have energy and rely on air vibration to transfer energy. The collection of sound waves is done by a sound wave sensor. The voice-activated LED tube uses a sensor usually called a microphone to work. Its sensitivity is relatively high. Generally, it can achieve -60dB, even if it is all installed in the aluminum tube of the lamp, the voice control function can be realized.
