Optical fiber lighting adopts the technology of blue light LD + long-distance optical fiber transmission + terminal white light excitation. Different from LED, the laser light source LD (Laser Diode) replaces the semiconductor light source with a laser light source to achieve electro-optical separation.Laser has multiple advantages over LED, including high power and low loss. In particular, its high collimation characteristic is highly compatible with the characteristics of optical fiber coupling and light guiding.LD light guiding lighting mainly solves the unavoidable one-to-one transmission mode of LED light guiding. It uses energy optical fibers and gradually distributes the energy in the main trunk to the lamps at the end of the branches through a dendritic light guiding network.It solves the material waste caused by multi-line laying on the one hand, and reduces the loss during light transmission and improves energy utilization efficiency on the other hand.

1）1.Electro-optical separation: the electro-optical host is placed at the back end, and transmission optical fibers are used to transmit light to the remote end, where white light is excited for illumination.
2）The LD light source has obvious advantages over the LED light source
· High power
· Low loss
· High collimation
It is highly compatible with the characteristics of optical fiber coupling and light guiding, with the advantages of long projection distance, high brightness, energy saving and compact structure.
3） High-efficiency LD optical fiber coupling technology and packaging process
It couples laser into optical fibers for transmission with high efficiency, and the coupling efficiency has reached 92%：
· Beam shaping: optimize beam quality to facilitate laser beam coupling;
· Beam convergence: converge the originally wide laser beam into a light spot with a diameter of about 50m, which matches the cross-sectional area of the multimode optical fiber core. Meanwhile, the angle is not larger than the fiber numerical aperture, meeting the conditions for high-efficiency coupling;Power flattening: make the power distribution of the light spot with a diameter of about 50m uniform.
4）Light Only, No Electricity
Optical fibers are non-electrified and heat-free, which can completely avoid the fire risk caused by lighting electrical equipment and circuits. In addition, no heat is generated during transmission, and the heat at the light output end is only one third of that of ordinary LED lamps.
5）Electromagnetically Interference-free
Electrical equipment is isolated through electro-optical separation, which can effectively avoid interference with sophisticated equipment in medical, scientific research and other fields.
6）Data Transmission
Optical sensing, LiFi technology and other technologies realize safety supervision while providing lighting.
7）Centralized Management
The photoelectric box is designed independently, which is suitable for heat dissipation and installed outside the warehouse for centralized management.

Different from traditional lighting methods, optical fiber lighting is a brand-new safe lighting method with the characteristics of non-electrification, non-heat conduction and no electromagnetic radiation at the transmission section and light output end.The optical fiber light guiding lighting system mainly consists of three parts: light engine, optical fiber and back end.It couples the light energy emitted by the LD light source into the light guiding optical fiber or light guide pipe and transmits it to the remote end, thus realizing the separation of the light source and the lighting area. The biggest advantage of this lighting method is electro-optical separation. Its emergence solves the lighting pain points of warehouses, mines, underwater and other places with high flammability and explosion risks.There is no need to worry about safety problems caused by power grid access, which truly realizes the vision of science and technology benefiting mankind and changing life.This type of product achieves intrinsic safety in the true sense.
