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. Big hidden problem

Embodiment 1

[0037] like figure 1 It is a schematic structural diagram of a single group of outdoor lighting devices, and the optical fiber coupling device 9 and the transmission optical fiber 5 are located in the lamp post 7; such as Figure 5 As shown, the laser headlight 8 includes a yellow phosphor filter 82, a reflection bowl 83 and a laser beam expander 84. The parallel blue light is outputted from the output end and then enters the laser beam expander 84 of the laser headlight 8, and the blue laser is uniformly irradiated to the laser beam expander 84 of the laser headlight 8. On the yellow phosphorus filter 82, a part of the blue laser and the yellow phosphorus filter 82 are excited and reacted to generate yellow light, and a part of the blue light is mixed with the yellow light generated by the excitation. The mixing ratio of blue and yellow light is 1:3, and the high efficiency white light is uniformly output To provide white light illumination for the road, the remaining part of...

Embodiment 2

[0040] like figure 2It is a schematic diagram of the structure of multiple groups of outdoor lighting devices. High-power laser diodes 2 can be used to output control street lights in series. The fiber coupling device 9 and part of the transmission fiber 5 are located outside the lamp post 7. The fiber coupling device 9 and the transmission fiber 5 are the corresponding two groups. , the beam splitter 6 divides the laser into two beams, one beam is transmitted to the laser headlight 8 through the transmission fiber 5, and the other beam is transmitted to the next beam splitter for splitting again, and so on, the beam splitter 6 only It is necessary to separate 6W of laser energy to provide enough energy to meet the brightness requirements of outdoor lighting areas;

[0041] like Image 6 As shown, the laser headlight 8 includes two groups of reflectors 81, a yellow phosphor filter 82 and a reflector bowl 83. The surface of the reflector 81 is coated with an all-dielectric re...

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 a high quality of life, but also pay attention to the rational use of resources, ecological protection of the environment, and the safety and humanization of devices. Outdoor lighting installations provide us with light in the dark night, and can be used for road lighting, industrial traffic lighting and sports venue 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 advanta...
