AI Technical Summary

Problems solved by technology

Irradiation from one side can lead to uneven curing of the top coat
[0018] In addition, the radiation must be guided through the protective tube by the arrangement of the radiation source and the protective tube, which leads to losses, especially if the protective tube becomes dirty during fiber drawing
[0019] The installation and removal of the protective tube is complex, since the protective tube has to be located between the fibers and the radiation source and the fibers have to be threaded in and out of the gaps in the radiation source in order to avoid damage to the radiation source
[0020] In addition, the radiation source must be positioned close to the fiber, thus increasing the requirements for gas flushing, and the packing density of LEDs cannot be arbitrarily increased

Embodiment Construction

[0064] In the fiber drawing direction 103 , the glass fiber 101 is guided vertically through the inner-coated quartz reflector 111 via a reflector inlet 115 and a reflector outlet 117 . The stretching of the glass fibers 101 takes place by means of known equipment.

[0065] A spraying device (not shown in the figure) is arranged vertically above the quartz reflector 111 of the inner coating, which spraying device functions as a coating device with nozzles. The glass fibers are sprayed with a liquid coating medium through these nozzles. The glass fibers 101 enter the reflector 111 in the wetted state with the coating medium. Circular narrow-band or broadband light-emitting diodes 105 are arranged outside and above the inner-coated quartz reflector 101 . These light-emitting diodes emit a spectral range of 200 nm to 2000 nm or 250 nm to 600 nm or 270 nm to 380 nm, depending on the choice. Alternatively, a plurality of light-emitting diodes with different spectral ranges can b...
