Optical fiber luminous line fluorescent illumination setting method convenient for fire-fighting lifesaving illumination

Abstract

The invention provides an optical fiber luminous line fluorescent illumination setting method convenient for fire-fighting lifesaving illumination, and relates to the technical field of lifesaving illumination lines, comprising the following steps: selecting a first preset current value and a second preset current value; when the electrifying current of the optical fiber light source is a first preset current value and a second preset current value respectively, carrying out a brightness experiment under the matching of multiple groups of protective leather sheaths to obtain a first brightness expression and a second brightness expression; a first weight factor and a second weight factor are introduced through verification; and according to the target surface brightness of the protective leather sheath, calculating to obtain the optimal fluorescent powder concentration and the thickness of the protective leather sheath. Fluorescence is excited by the optical fiber light-emitting line for illumination, the total mass of the illumination line is effectively reduced, the illumination line can extend to a longer rescue channel for illumination, photoelectric separation can be achieved in the optical fiber illumination line, the illumination line is in a power-free state during use, safety is high, fluorescence excitation is sufficient, and illumination brightness of the illumination line is high; and the service life can be effectively prolonged by optical fiber luminescence.

Description

technical field [0001] The present invention relates to the technical field of lifesaving lighting lines, and in particular, the present invention relates to a method for setting fluorescent lighting of optical fiber light-emitting lines that is convenient for firefighting and lifesaving lighting. Background technique [0002] The life-saving lighting line is a facility that provides lighting and indicates the direction of evacuation after the power line is cut off in the event of a fire or other accident. [0003] At present, the line body of the fire-fighting and life-saving lighting line is a fluorescent light-emitting line, with an EL cold light source embedded in it, which can be excited into any color by fluorescence. For example, Chinese patent utility model patent CN209245761U discloses a life-saving lighting line, which includes a light-emitting line and emits light. The light is flatly wound on the wheeled rubber plate, and there are several transparent sleeves wit...

Problems solved by technology

[0004] However, the above-mentioned life-saving lighting lines still have the following defects: 1. According to market research, the phosphor concentration ratio of the current lighting lines is about 0.3%. Not less than 10cd / m2, the quality of the line body is not greater than 13kg and other parameters, the longer the length, the lower the luminous brightness, and the heavier the line body quality, resulting in the longest specification of the existing lighting line being 200 meters, which is far lower than the actual situation of rescuers. Use requirements; 2. The light source in the lighting line is usually an EL electroluminescent line. When the 12V DC power supply is changed to a 110V high-voltage AC power by the driver for a long distance, the line body emits light. When it is in use, it is powered all the way, and there are certain safety hazards; 3. EL The luminous efficiency of the light source is low, resulting in low luminous brightness, which is also an important reason for the limitation of the distance of the lighting line; 4. The average service life of the EL electroluminescent line is 3000-5000 hours, which makes the service life of the lighting line relatively low
