Description

Technical Field

[0002] With the reduction of fossil energy such as oil and coal, the research and development of new energy and new materials is a feasible strategy to promote green and energy-saving transformation of cities and towns. Among them, photoelectric separation safety lighting technology is an advanced lighting technology. It converts electrical energy into light energy and uses transmission media such as optical fiber to transmit light energy to lighting equipment, thereby achieving photoelectric separation and ensuring the electrical safety of the lighting system. The safety and reliability of photoelectric separation are usually used in tunnels, mines, forest lighting, etc.

[0003] Traditional lighting technology generally uses halogen lamp lighting and plastic fiber optic lighting; halogen lamp lighting is a light source composed of gas discharge lamps. It is used in many fields because of its good color rendering, strong penetration and low energy consumption. However, the heat dissipation effect is poor, which causes damage to the inside of the lamp and reduces its service life; and because a power cord is set at one end of the halogen lamp, the power cord is hot and easy to age, leading to dangers such as electric shock and leakage. Plastic fiber optic lighting is composed of a light source, optical fiber and a drive device. Plastic fiber optic lighting is based on the phenomenon of total reflection of light. The light from the light source generator is transmitted to the designated area through the optical fiber to achieve lighting. Due to the non-conductivity of the optical fiber, it is safer in flammable and explosive environments. However, plastic fiber optic lighting is prone to oxidative degradation in high temperature environments, affecting its service life and stability.
