Introduction of infrared ray to tube principle

When the infrared ray is emitted to control the corresponding controlled device, the control distance is proportional to the transmitted power. In order to increase the control distance of infrared ray, the infrared generator tube works in the pulse state, because the effective transmission distance of pulse light (modulating light) is proportional to the peak current of the pulse, the transmission distance of infrared ray can be increased by improving the peak Ip as far as possible.
