Optical fiber transmission lighting device

Abstract

The invention provides an optical fiber transmission lighting device. By means of a circuit control system and a cooling system, a lasing diode is controlled to output 450 nm blue single-frequency lasers stably and continuously, the 450 nm blue single-frequency lasers are coupled into transmission optical fiber by an optical fiber coupler, a laser headlight receives parallel beams transmitted by optical fiber, after beam expansion is conducted, the parallel beams are in motivating reaction with a yellow phosphorus filter inside the laser headlight so as to be switched into 540 nm yellow light, mixing light with blue light and the yellow light being 1:3 is formed finally, and white-light illumination with high luminance is achieved. Due to the fact that optical fiber transmission is adopted in the device, separation of light and electricity is conducted, the optical fiber transmission lighting device is an safe, energy-saving, non-pollution, green and outdoor lighting device, and the problems that the energy consumption outdoor lighting is large, detection and maintenance are troublesome, and the potential safety hazard is large are solved.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to an optical fiber transmission lighting device. Background technique [0002] With the development of the economy and the improvement of living standards, people not only pursue high quality of life, but also pay attention to the rational use of resources, ecological protection of the environment, safety and humanization of devices. Outdoor lighting devices provide us with light in the dark night, and can be used for road lighting, industrial traffic lighting, and sports lighting. [0003] At present, outdoor lighting devices mainly include high-pressure sodium lamp lighting devices and LED lamp lighting devices. The former is the mainstream lighting device for outdoor lighting today, and the latter is a new type of energy-saving light source, which is gradually being applied to outdoor lighting projects and is developing rapidly. Both have their own advantages and application o...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides an optical fiber transmission lighting device, which controls the laser diode to stably and continuously output 450nm blue single-frequency laser through the circuit control system and the cooling system, and is efficiently coupled to the transmission by the fiber coupler. In the optical fiber, the laser headlight receives the parallel beam transmitted by the optical fiber, and after the beam is expanded, it undergoes an excitation reaction with the yellow phosphorus filter inside the laser headlight and converts it into 540nm yellow light, finally forming a 1:3 mixed light of blue light and yellow light , to achieve white light lighting with high brightness, because the device uses optical fiber transmission, and the photoelectricity is separated. It is a safe, energy-saving, and pollution-free green outdoor lighting equipment, which solves the problem of high energy consumption, troublesome inspection and maintenance of existing outdoor lighting technology, and safety.
