Definitions

  • the invention relates to radiation protection glasses with filters arranged in a spectacle frame that absorb harmful radiation.
  • the radiation harmful to the human eye is mostly in the invisible spectral range, i.e. i.e. in the UV or in the I.R. Radiation in the visible range can also be harmful if its intensity exceeds a certain threshold.
  • laser rangefinders are increasingly used, which emit very short pulses in the near or middle infrared to measure the target. It is therefore not possible for individuals to see whether they and their surroundings are in the target area.
  • Such glasses offer the possibility of setting the threshold discriminator to two different signal levels.
  • a warning signal is generated which indicates to the user of the glasses that he is in the area of the invisible radiation.
  • a warning signal different from the first is generated, which indicates to the user of the glasses that their protective effect is no longer sufficient.
  • the radiation protection glasses are expediently designed such that the sensor has bandpass or high-pass characteristics in connection with the downstream electrical elements, and that the threshold discriminator is set to detect rise times of different speeds. This enables the typical short pulses of a laser range finder to be detected and the user to be warned.
  • Spectacles are known from EP-OS 00 78 473, the frame of which is connected to a sensor for measuring the illuminance in the visible spectral range.
  • the glasses of these glasses are provided with an electrochromic layer and the sensor is followed by an electronic evaluation system that changes the degree of absorption of the electrochromic layers depending on the measured illuminance.
  • the transmission is not automatically adapted to the irradiance, but the user attention is drawn to the invisible radiation and must take the appropriate measures itself.
  • Such glasses are of course much cheaper than the known glasses with electro-chrome layers; it protects the user just as reliably and can also be produced for any desired spectral range.
  • subclaims 2-7 Further expedient refinements of the radiation protection goggles according to the invention are the subject of subclaims 2-7, while subclaim 8 specifies a particularly advantageous use of the radiation protection goggles.
  • FIG. 1 shows a perspective illustration of an exemplary embodiment
  • Fig. 2 shows a temple of the glasses of Fig. 1;
  • FIG. 3 shows the front view of another exemplary embodiment
  • Fig. 4 shows another embodiment in side view.
  • the radiation protection glasses shown in FIG. 1 contain two radiation protection filters 2 and 3 in a frame 1.
  • the arms of the glasses frame are designated 4 and 5.
  • two sensors 6 and 7 for invisible radiation are integrated near the folding hinges for the bracket 4.5. These sensors respond to radiation that is attenuated by filters 2 and 3.
  • a sensor 8 can also be arranged on the noseband of the holder 1.
  • the temple 5 is shown so that the components integrated into it are visible. These consist of a line 9 which feeds the signal generated by the sensor 7 to an amplifier 10 and from there a threshold discriminator 11. This, as well as the amplifier 10 are from a button cell battery via a line 12 rie 13 supplied.
  • the sensor 7 supplies a signal which triggers a warning signal when the first signal level set at the discriminator 11 is exceeded. This is generated, for example, as a continuous tone which can be heard by the user via the buzzer 14.
  • the intensity of the radiation exceeds a value which can no longer be attenuated by the filters 2 and 3 to an intensity that is harmless to the user, the signal applied to the discriminator 11 exceeds the second set level and the buzzer 14 becomes an, for example intermittent Warning signal audible. For the user of the glasses, this is the sign to leave the harmful radiation area immediately.
  • the sensors 6, 7, 8 can be designed as photoelectric or thermoelectric receivers, which are provided with an edge filter selected according to the protective area. This is so designed that it only lets through the spectral range of the radiation that is absorbed by the filters 2, 3. This radiation can be in the UV or infrared range, for example.
  • an optical fiber 15 is embedded in the socket 1, which surrounds the filter glasses 2, 3 and the ends of which are coupled to a sensor 16.
  • the fiber 15 fluoresces and the sensor 16 is exposed to the fluorescent radiation.
  • 3 is expediently equipped with ear hooks corresponding to FIG. 2, the signal from sensor 16 then being fed via line 9 to the subsequent switching elements.
  • the fiber 15 can, for example, also run in the ear hooks.
  • the optical fiber 15 is inserted into recesses in the spectacle frame 1, which are then closed with a material which has the effect of the edge filter described above.
  • 4 shows an embodiment in which the holder 17 for the filter lenses is provided on the eyebrow side with a hinge 18.
  • a filter lens 19 is fastened in a hinged manner in this hinge.
  • a sensor for the dangerous radiation is designated 20.
  • These glasses can be designed so that the frame 17 contains no filter lenses.
  • the user first works with the filter lens 19 folded up. As soon as the sensor 20 supplies a signal that can be heard via the buzzer 14 in the bracket 5, the user folds the filter lens 19 down so that his eyes are now protected.
  • the sensors 6, 7, 8 have bandpass or high-pass characteristics in connection with the downstream amplifier 10 and the discriminator 11 is set to discriminate signal rise times of different speeds. This makes it possible to detect the pulses from laser rangefinders, which typically work with very short pulses with pulse widths in the range of a few nano-seconds and pulse rise times of a few hundred pico-seconds.
  • filter lenses in the mount 17 from the outset. It is first worked with the filter lens 19 folded up. As soon as the warning signal of the second stage sounds, which signals that the filter effect of the glasses is no longer sufficient, the user folds the additional filter lens 19 down. It is expedient to design the filter lens 19 such that a part of this lens is also arranged in front of the sensor or sensors 20 after folding. After the filter lens 19 has been folded in, the warning signal of the second stage also stops.
  • the radiation protection glasses shown and described are used with particular advantage as laser safety glasses in addition to their use in the military field.

Abstract

Des lunettes de protection contre des rayonnements dont la monture (1) est munie de filtres (2, 3) qui absorbent les rayonnements nuisibles comprend des senseurs (6, 7, 8) de rayonnements invisibles. Un discriminateur ajustable de valeur de seuil connecté à un dispositif d'alarme (14) est monté en aval des senseurs. Dès que le porteur des lunettes pénètre dans une zone de rayonnement invisible, les senseurs émettent un signal qui déclenche un signal d'alarme. Lorsque l'intensité des rayonnements nuisibles dépasse une valeur qui ne peut plus être réduite par les lentilles de filtrage jusqu'à une valeur acceptable, un deuxième signal, facile à distinguer du premier, est déclenché.
