Abstract

The invention discloses a battery-powered portable optical fiber light source driving device. The device comprises a built-in battery power supply unit, a constant current output circuit, a temperature control circuit and a light source driving state indication unit. A lithium ion battery can be used for power supply of the device, and normal work can be driven without a boosting switching circuit. The constant current output circuit provides precise and adjustable stable current to drive a tube core of a light source to emit light; the temperature control circuit detects the state of the light source and regulates temperature control current to adjust the temperature of the tube core based on a pulse width modulation principle, and the driving state indication unit reflects state information including light source constant current, lithium battery charging and tube core temperature comprehensively through external light change and a buzzer. The device is portable, small in size, high in temperature control efficiency, capable of effectively eliminating power frequency interference, and capable of being widely applied to detection, driving and quick system failure checking of sensing and communication optical fiber sources.

Description

technical field [0001] The invention relates to the technical field of driving a light source used in the field of optical fiber sensing and communication. In particular, it relates to a battery-powered light source driving and indicating device with constant current output and constant temperature control. The device is portable and compact, and can be widely used in the detection of optical fiber sensing light sources, and solve practical problems such as rapid troubleshooting and the influence of power grid instability. Background technique [0002] Optical fiber sensing technology can realize accurate sensing of sound, light, force, heat, electricity, displacement and other physical quantities, and plays an important role in aerospace, military, metrology and other fields. Since optical fiber sensing must have a stable light source, the light source driving device needs to provide constant driving current and stable temperature control for the optical fiber sensing ligh...
