How is the infrared 1.2m led tube produced?
Principle of infrared 1.2m led tube: Adopt pyro-infrared sensor head, also called sensor. The induction of a specific infrared frequency controls the constant current power supply of the led, thereby controlling the work of the infrared led tube.
Infrared 1.2m led tube structure:
1. T8 aluminum, length 1175+1175PC lampshade.
2. Aluminum substrate, with 2835led lampshade affixed to it for easy heat dissipation
3. Power supply, the key component of infrared LED tube. It is divided into two parts, one is the power control part, by adjusting the control current, the total power of the led tube can be changed to control the work of the led string. The other part, the induction head part, has an induction sensor inside, and an induction collector. The PCB board can adjust the charging and discharging time, that is, the RC circuit. By adjusting this circuit, you can control and change the delay time from 30 seconds to 2 minutes. Realize the delay function. Regarding the sensing distance, it is determined by the sensor. The sensitivity of the led tube depends on the size of the sensor window. The window is large, the collected signal is strong, and it is more sensitive. The general distance is 5-8 meters.
4. Process tips: Infrared LED tubes have an effect on strong light. During the production process, pay attention to blocking the light of the led lamp beads at the bottom of the sensor head. Otherwise, it will affect the sensitivity of the led tube.
Infrared 1.2m led tube test and use:
Note: During the test, the object (person) should be cut along the sensor head, not towards the sensor head. The installation density is too large, and it also affects each other.
Infrared 1.2m LED tube application:
It is widely used in underground garages, aisles and other occasions that require automatic control.
