The invention belongs to the technical field of illumination, and particularly discloses a multi-tube laser conduction illumination system adopting echo infrared detection. The multi-tube laser conduction illumination system comprises the multi-tube laser conduction illumination system, an infrared detection system, a control circuit and a power supply unit, optical fiber conduction is adopted, photoelectric separation is achieved, and illumination safety is improved; transmission-type excitation is adopted, so that the light extraction efficiency is improved, the service life of blue-light LDs is prolonged, and meanwhile, the safety is also improved; the plurality of blue-light LDs are adopted, so that the single-fiber energy can be effectively improved, the number of optical fibers is reduced, and the construction cost is saved; and the infrared detection system is adopted, an independent infrared optical fiber is adopted, the light extraction condition can be monitored in time, if a transmission optical fiber is broken, a photoelectric element PD cannot receive red light reflected by a third light filtering system, and therefore an instruction of cutting off a power source is given, and safety is improved. The multi-tube laser conduction illumination system adopting echo infrared detection has the advantages of being high in light extraction efficiency, high in safety and the like.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a multi-tube laser conduction lighting system using echo infrared detection. Background technique [0002] Traditional lighting mainly adopts the method of arranging electricity in the area that needs to be illuminated, and then converts the electrical energy into light through a photoelectric conversion chip, and then performs lighting after photoelectric conversion. This kind of lighting is easy to cause safety accidents because the photoelectric conversion is in the lighting area, while laser light Conducted lighting mainly uses remote photoelectric conversion, and then transmits the light of a specific wavelength to the place where it needs to be applied through an optical fiber, and then converts the light of a specific wavelength into the required white light through phosphor technology, so as to achieve no electricity in the use area. , to achieve photoelectri...

AI Technical Summary

Problems solved by technology

[0003]Laser light transmission lighting mainly uses light transmission. Since the optical fiber is made of silica fiber with a small core, the optical fiber may break under the action of external force. After the optical fiber breaks, the entire lighting is in a state of no lighting. If the power is not cut off in time, the light of a specific wavelength will be on for a long time at the broken position, and the broken position is in a closed state, and the energy cannot be fully released. If the heat reaches a certain level, it will cause damage to the entire lighting system, and if the heat is too high, it will cause fire or damage to surrounding materials
