What is the principle of induction lamp?
The principle of the induction lamp is what kind of infrared induction lamp, then this kind of induction lamp is also set by sensing the infrared of the human body. Because the average human temperature is about 37 °, and a fixed wavelength of about 10 microns of infrared light will be emitted.
What is the principle of led induction light bulb? The LED body sensor lamp uses the thermal infrared radiation produced by human beings.
Electromagnetic induction lamp is a kind of lamp made by electromagnetic principle. This kind of lamp can be induced by battery and can emit light by sensing gas and sound in the air.
Induction lights generally use infrared to sense the heat released by the human body, not only people, as long as there is a temperature object can be sensed, once the induction lamp detects heat, it will release a current signal, thus issuing an order to turn on the LED lamp.
The principle of the touch induction lamp is that the electronic touch ic is installed internally and the electrode piece at the touch place of the lamp forms a control loop.
The principle of the induction lamp is to use infrared light to sense the heat energy released by the human body. Most objects with temperature can be detected. After the induction lamp detects the heat energy, it will release a signal and issue instructions to the LED lamp.

The proper name of this thing on the market is the infrared human body sensor switch. When the human body walks within the distance that can be sensed by the induction switch, the circuit makes the relay absorb 220V through processing, and the light will come on. If the human activity is sensed again between the lights, the time continues to increase.
The sensor transmits the measured values of temperature, pressure and flow to the computer through the cable so that the operator can see the actual value of the site in the office.
When the unidirectional thyristor is turned on, the lamp will brighten normally. When the sound signal disappears, the diode turns off, the Triode ② and Triode 9015 no longer work, but through capacitive discharge, the Triode ③ can still be turned on for a period of time and provide current to the unidirectional thyristor.
The current produced by a photosensitive diode illuminated by light of general illumination is called photocurrent. If the load is connected to the external circuit, the electrical signal is obtained on the load, and the electrical signal changes accordingly with the change of light. Photosensitive diodes and phototransistors are widely used in electronic circuits.
As the name implies, a thermistor is a resistance that is sensitive to heat, and the function of a resistor is to limit the current passing through and change the voltage on both sides of the resistor. You can use either one, but it must be the same as the unit. So sensors that accept temperature changes can be divided into current and voltage. Take the current if the current sensor is to be used.

Infrared human body induction lamp, principle: using one send and receive active infrared technology, integrated codec transmission, decoding reception, control output, 8-bit single-chip microcomputer production function is powerful, using industrial district-level chip, wide load capacity, strong anti-interference ability, suitable for any place.
Principle: it is actually an automatic switch control circuit, there are many types, the way of closing (that is, turning on the light) of the switch is “voice control”, “trigger”, “induction”, “light control” and so on. The way of opening is basically the same. controlled by a delay circuit (automatically disconnected after working for a period of time).
