Definitions

  • the invention relates to light source for active safety clothing equipment or a means of line irradiation with a side-emitting light guide enclosed in a textile sheath provided with at least one fastening means for attachment to a carrier element or clothing on at least part of the length of the light guide while the light source is connectable with a source of electrical energy.
  • passive retro-reflective elements and/or actively light-emitting elements positioned on the outer side of the clothing that are used most often.
  • the actively light-emitting elements are typically based on battery-powered groups of lighting units, particularly LEDs, which are mounted onto the surface of a carrier means.
  • the advantage of the passive retro-reflective elements is their zero energy consumption and high mechanical resistance.
  • the advantage of the actively light-emitting elements is their functionality even without external irradiation which is possible due to internal power supply.
  • the greatest drawback of the use of the passive retro-reflective elements is the fact that their functionality is limited only to situations when the element is irradiated by an external source of light (e.g. car lights, etc.). This is unfavourable especially in situations, such as when a person moving along the road or in its vicinity is not irradiated by the headlights of a car until at a certain moment, and is therefore seen by the driver later than could have been seen, which applies especially to bends and other less clear sections of the road.
  • an external source of light e.g. car lights, etc.
  • the greatest disadvantage of actively radiating elements is the necessity of ensuring their power supply, usually by using batteries, whereby for highlighting a larger area it is necessary to use a plurality of light-emitting elements (units), e.g. LEDs, which then consume a greater amount of energy.
  • this arrangement occupies a relatively vast area and is therefore hardly suitable for clothing, also because it is bulky and inflexible or, in other words, has limited flexibility, and, last but not least, each of the illuminating elements is dependent on power supply delivered directly into it, which is from the technical point of view considerably demanding, especially when trying to achieve a high quality and durability.
  • a line source of light that is used (fluorescent tubes), or a row of point sources of light arranged behind one another (bulbs, LEDs). This relates especially to the illumination within corridors or hallways, creating light direction indicators or the light marking of obstacles in a path, the light marking of outlines of objects, the highlighting of edges, such as stairs, emergency exits, etc.
  • LEDs arranged in a band seem to be more advantageous than bulbs, discharge lamps and fluorescent tubes, LEDs exhibit a high light intensity, which often even dazzles and must be attenuated by various filters, which makes their use more expensive.
  • Another shortcoming is the fact that the construction of a band of a group of LEDs leads to formation of a longitudinal element with a relatively limited flexibility.
  • a common disadvantage of bulbs, LEDs, discharge lamps and fluorescent tubes is the necessity to secure corresponding power supply for each elementary light source.
  • Another drawback is their limited applicability in regions with no power supply, especially during power outages, since their relatively high energy consumption puts high demands on securing alternative sources of electrical energy.
  • a common problem of point light sources is local over-illumination which causes illumination of only a relatively limited space around the light source.
  • the aim of the invention is to remove or at least minimize the drawbacks of the background art.
  • the goal of the invention is achieved by light source for active safety clothing equipment, whose principle consists in that the light source comprises an LED or laser diode with the maximum radiating angle of 50° (FWHM) and the radiation output in the range from 10 to 500 Im, whereby the LED or laser diode is connected to an aluminium board and a printed circuit of the electronics of the light source and the light source is equipped with orifice for enter the light guide with its inlet end to the inner space of a housing and is further equipped with at least one centering means for holding the inlet end of the light guide in a stable position in relation to the LED or laser diode and the whole set is mounted in the housing in a waterproof manner.
  • the light source comprises an LED or laser diode with the maximum radiating angle of 50° (FWHM) and the radiation output in the range from 10 to 500 Im
  • the LED or laser diode is connected to an aluminium board and a printed circuit of the electronics of the light source and the light source is equipped with orifice for enter the light guide with its inlet end to
  • the advantage of this arrangement is the fact that it enables to create an actively light-emitting clothing equipment or a means of line irradiation with minimum energy consumption, which is easily usable on different garments, is easily wearable and is also widely configurable in terms of the arrangement of irradiated parts, etc.
  • Other advantages include the absence of local over-illumination or glare, long life, low energy consumption, resistance to damage of the light guide, color variability, easy replacement, etc.
  • Examples include carpet edges, bath sets, outdoor rugs and doormats, escape routes and exits, marking of the shape of stairways, lifts or hospital beds, road barriers, premises for the police, firefighters, rescue services or construction sites or landing and parking areas for air and land means of transportation, wherein due to high uniformity of illumination there is no local over-illumination and the light source is not dazzling.
  • Another advantage is the possibility of highlighting parts of objects which have their own electrical system, such as ships, cars, motorcycles.
  • Other uses include, for example, highlighting canvas of lorries or trucks, opened doors, local illumination of the interior, etc.
  • Other possible applications relate to illumination to ensure greater safety in conditions of reduced visibility, e.g. illumination of bicycles, baby carriages, wheelchairs and carts, canes and crutches, warning signs including warning triangles, etc.
  • Another field of application is illumination for advertising purposes and in industrial processes.

  • the width of the textile stripe is usually in the range of 2 cm to 5 cm. Nevertheless, in general, it is possible to create a textile sheath 2 with a light guide 1 without a textile stripe 20 .
  • Covering the light guide 1 by the textile sheath 2 and creating textile stripes 20 is performed by any of several known methods of weaving, knitting and interlacing in different patterns, using a wide range of textile materials on machines which enable to produce textile stripes with firm edges, as well as tubular and Jacquard weaves.

  • the textile sheath 2 of the light guide 1 is provided with means, e.g. fibers, etc., which respond to the light emitted by the light guide 1 , so that having been irradiated, they themselves "radiate" (fluorescent effect), thereby enhancing the light impression of the means of line light exposure.
  • the textile sheath 2 can also be provided with transverse and/or longitudinal stripes differing in color or in the content of a fluorescent compound, etc.

  • a separate carrier means e.g. to a system of specially constructed belts with clasps or buckles
  • the textile sheath 2 with the light guide 1 is formed as an enclosed structure (e.g. shaped as a circle), which the wearer places loosely on a suitable part of a garment, e.g., puts it on a hat, puts it around the leg above the calf (just below the knee) and the thus shaped (circle-shaped) textile sheath 2 with the light guide 1 cannot fall off the wearer due to gravity.
  • an appropriately formed attachment means e.g. shaped as a circle
  • the textile sheath 2 is provided with an adhesive layer, which the wearer simply glues on a piece of clothes in any place, of any rounded shape, in any direction and in this manner creates instantaneous active safety clothing equipment for immediate use.
