Description
Technical field:
This utility model is a kind ofly can avoid eye damage in the operation that the point-like intense light source is arranged, and light sensation that again can clear observation operation situation becomes light focal spot reduction protective eye lens.
Background technology:
Now, to the protective eye lens that uses in the operation that the point-like intense light source is arranged, it includes face shield, is provided with one and observes slotted hole on face shield, observes in the slotted hole glassy layer and optical filter are installed from outside to inside successively, is connected with handgrip in the face shield bottom.Also having a class is the electronic liquid crystal protective eye lens, and it roughly is divided three classes, the one, and light sensing formula, the 2nd, wired flux sensing formula, the 3rd, wireless flux sensing formula.The light sensing formula because from the optoelectronic induction to the signal processing and liquid crystal become light, required time is long, harmful light is easily in earlier stage passing through filter disc in the use.The shortcoming of wired flux sensing formula is that wire influence is arranged, and uses inconvenient.The shortcoming of wireless flux sensing formula is when many common operations of welding are arranged, easily to disturb mutually.In addition, this class protective eye lens has inclination that light transmittance is acutely strengthened in use slightly, protects the order weak effect, and the flux sensing formula to cause intense light source for non-electricity then powerless.
Summary of the invention:
The purpose of this utility model provides a kind ofly can avoid eye damage in the operation that the point-like intense light source is arranged, again can clear observation operation situation, easy to operate light sensation becomes light focal spot reduction protective eye lens.
The technical solution of the utility model is finished as follows; it includes a face shield; the face shield bottom is fixed with handgrip; it is characterized in that: correspondingly with eyes on face shield have two observation ports; be separately installed with a mirror holder in each observation port; mirror holder is interior from cover glass outside to inside is installed successively; optical filter; liquid crystal becomes mating plate and focal spot reduction filter disc; one photosensitive head is installed on the face shield between two mirror holders; at four jiaos of each mirror holders and four jiaos of adjusting fixing holes that are respectively equipped with mutual correspondence of each observation port; be provided with two positioning belts in that mirror holder is parallel on the face shield of both sides up and down; between two observation ports, be provided with an illuminating lamp above the last positioning belt; treatment circuit and switch and power supply are installed in handgrip, have lead to be communicated with liquid crystal on the treatment circuit respectively and become mating plate; illuminating lamp; photosensitive head; switch and power supply.The illuminating lamp that this utility model is installed is the light-pulse generator illuminating lamp, its single frequency cycle less than 0.02 second, greater than the required time of processing circuit processes signal.Ray filtering material on focal spot that this utility model the is installed reduction optical filter on filter disc by the outside diffusion profile in center.The startup light frequency of photosensitive head be higher than the illumination optical frequency, smaller or equal to the operation optical frequency, the executive component of circuit start effective optical frequency illumination be higher than the sum total of ambient light illumination and lighting illumination intensity, smaller or equal to the operation light illumination.
The utlity model has safe and reliable, observing effect good, easy to operate advantage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the planar structure sketch map of mirror holder,
Fig. 3 is an electrical schematic diagram of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, this utility model includes a face shield 1 and handgrip 10 thereof, correspondingly with eyes on face shield have two observation ports, be separately installed with a mirror holder 7 in each observation port, mirror holder is interior from cover plate 8 outside to inside is installed successively, optical filter 5, liquid crystal becomes mating plate 4 and focal spot reduction filter disc 3, on two intermediary face shields of mirror holder, one photosensitive head 9 is installed with installing hole, be respectively equipped with and four jiaos of corresponding adjusting fixing hole 7-1 of each observation port of face shield four jiaos of each mirror holders, about mirror holder, be respectively equipped with a positioning belt that is parallel to each other 2 on the face shield of both sides, an illuminating lamp 6 is being installed on the face shield between two mirror holders above the last positioning belt, a treatment circuit 11 is installed in handgrip, on treatment circuit, there is lead to be communicated with liquid crystal respectively and becomes mating plate, illuminating lamp, photosensitive head also is provided with a switch 12 that is communicated with treatment circuit and power supply 13 on handgrip.The illuminating lamp that this utility model is installed is the light-pulse generator illuminating lamp, its single frequency cycle less than 0.02 second, greater than the required time of processing circuit processes signal.Ray filtering material on focal spot that this utility model the is installed reduction optical filter on filter disc by the outside diffusion profile in center.The startup light frequency of photosensitive head be higher than the illumination optical frequency, smaller or equal to the operation optical frequency, the executive component of circuit start effective optical frequency illumination be higher than the sum total of ambient light illumination and lighting illumination intensity, smaller or equal to the operation light illumination.Operation principle of the present utility model is, obstructs the light with face shield during the user operation, and when the switch on the handgrip disconnected, because the protection of optical filter is arranged, observed environment was relatively darker; When switch closure, the work of pulsing light lamp, but because the reason of persistence of vision, what see is an environment clearly; When the moment of user striking low-light (level) shortwave light cause photosensitive head work, this moment illuminating lamp also in work, but because hot spot is positioned at the center of focal spot reduction filter disc, so can not damage.Liquid crystal becomes the moment deepening of mating plate before electric arc formally ignites, because the pulsed light cycle will be longer than the circuit response time, so become the mating plate deepening synchronously though light is closed with liquid crystal, light stops can not to lag behind the deepening of change mating plate.After electric arc formally ignited, visually hot spot was covered by the center of focal spot reduction filter disc, and the protected while of eyes has also reduced the physiological of pupil shrinks, and its effect is that the observation meeting is more clear.
