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

Description

technical field [0001] The invention belongs to the technical field of illumination, and in particular relates to an echo detection multi-tube laser conduction illumination system. 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 photoelectric sepa...
