Description
Technical field
This utility model relates to the Function Extension field of eyesight detecting instrument, relates in particular to a kind of LED eyesight testing apparatus.
Background technology
In the time of health check-up, test vision is the most basic health check-up project.When generally health check-up vision, need two health care workers to cooperatively interact and just can complete, a medical worker gives directions on visual acuity chart, and another medical worker is responsible for observation process and records result.The method of this kind of traditional detection vision has two defects: the first, and the medical worker who gives directions, is a thin ear of maize while generally use, must aim at alphabetical position, give directions, give directions and covered captions if artificial, need again to adjust, therefore pretty troublesome; The second, the medical worker who is responsible for observation and record, easily because checking UP for a long time, generation is tired, causes distant surveillance mistake, generation misregistration.
Utility model content
For problem set forth above, be necessary to provide a kind of, do not need double cooperation, the strength detector that can test eyesight fast.
A kind of LED eyesight testing apparatus, comprises vision dash board, battery, control panel.
Optimize, described vision dash board is double-decker, and described double-decker is made up of base plate, cavity, top panel, and described top panel is described front, and front is printed on visual acuity chart; Each letter of described visual acuity chart has a LED lamp, and described LED lamp is positioned at the double-deck cavity of vision dash board, be on described base plate, and the position corresponding with letter.
Optimize, described LED lamp connects battery and control panel by electric wire; Described control panel has display, has touch pad, on and off switch on display.
Optimize, after described control panel turns on the power switch, show miniature visual acuity chart on display, click corresponding letters, LED lamp can be shinny behind for described visual acuity chart.
Optimize, the battery described in described LED eyesight testing apparatus is rechargeable lithium batteries, and the visual acuity chart backboard portion described in described LED eyesight testing apparatus has charging jack, and described charging jack is pin type charging jack.Because be not to find suitable plug position at health check-up scene at every turn, because TunePower can be avoided when not having in socket situation, can continue to use, and the power consumption of LED lamp is minimum, therefore can use the long period.
Improvement by this utility model to normal vision detector, utilizes that control panel control is each refers to flickering of alphabetical LED lamp, not only can reduce medical worker's quantity, and use more convenient.
Brief description of the drawings
Fig. 1 is this utility model LED eyesight testing apparatus population structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present embodiment is described further.
As Fig. 1 this utility model discloses a kind of design of LED eyesight testing apparatus.Comprise vision dash board 1, battery, control panel 2.
Described vision dash board 1 is double-decker, and described double-decker is made up of base plate, cavity, top panel, and its material is pc material.Described top panel is described front, and front has visual acuity chart 3, described visual acuity chart 3 in the present embodiment, the E letter visual acuity chart of the international standard of employing, wherein maximum E letter is of a size of: 12.5cm 10cm 8cm.
Each letter of described visual acuity chart 3 has a LED lamp, and described LED lamp is positioned at the double-deck cavity of vision dash board 1, be on described base plate, and the position corresponding with letter.
Further, in the present embodiment, the color of described LED lamp is chosen as redness, the color of selecting due to the printing of visual acuity chart 3 is generally black, with white led lamps, although the interference ability of the identification to black letters is minimum, uses white led lamps daytime, can cause the indefinite effect of instruction.Therefore select to there is obvious contrast with black, in situation, have the red LED lamp that can obviously recognize by day.
Further, described LED lamp connects battery and control panel 2 by electric wire 4; Described control panel 2 has display 5, has touch pad, on and off switch 6 on display 5.After described control panel 2 turns on the power switch 6, show miniature visual acuity chart on display 5, click corresponding letters, LED lamp can be shinny behind for described visual acuity chart 3.
Further, described control panel 2 has automatic winder; Convenient for collecting electric wire 4, and adjust to Len req.
Further, the battery described in described LED eyesight testing apparatus is rechargeable lithium batteries, and vision dash board 1 back described in described LED eyesight testing apparatus has charging jack, and described charging jack is pin type charging jack.Because be not to find suitable plug position at health check-up scene at every turn, because TunePower can be avoided when not having in socket situation, can continue to use, and the power consumption of LED lamp is minimum, therefore can use the long period.
Improvement by this utility model to normal vision detector, utilizes that control panel control is each refers to flickering of alphabetical LED lamp, not only can reduce medical worker's quantity, and use more convenient.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
