Abstract
The utility model discloses a novel medical visual chart lamp, comprising an outer frame, an inner frame attached to the inner edge of the outer frame, a luminous body enclosed by the outer frame and a power-on device connected on the luminous body, wherein the luminous body in the outer frame is an organic light-emitting diode (OLED), the luminous body enclosed by the outer frame is a large-size integral OLED or is a rectangular luminous body formed by splicing a plurality of large-size OLEDs. The novel medical visual chart lamp has the advantages that the design structure is simple, the power consumption is low, the heating quantity is less, the portability is strong, the luminescence is uniform and the display is clear in the sun; and the novel medical visual chart lamp can realize a function for inspecting vision well after the OLED is lightened.
Description
Technical field
This utility model relates to far away, the near vision of health check-ups such as a kind of child of mensuration, the general health check-up of teenager, enrollment, recruitment and is used for the light fixture of other purpose test near and distance, especially a kind ofly be the new medical visual acuity chart light fixture of luminous body with Organic Light Emitting Diode (OLED, English full name are Organic Light Emitting Diode).
Background technology
At present, widely used medical visual acuity chart adopts daylight lamp as luminous body, adopt aluminium alloy to make casing, case is embedded in daylight lamp as light source, look dash board and select poly (methyl methacrylate) plate for use, its surface is painted with international standard visual acuity chart, logarithmic visual acuity chart, Lan Shi (Landolt) ring visual acuity chart or other kind visual acuity charts.Under than the half-light environment, the subjects is positioned at the inspection distance, and the some bright light source by doctor's requirement, is carried out test near and distance.But its shortcoming is, uses daylight lamp as light source, has dim light in the sun, portability is poor, caloric value is high, power consumption is big shortcoming, so, adopt the light fixture of this luminous body not meet the requirement of 21 century energy-saving and emission-reduction.
Summary of the invention
Shortcomings such as caloric value height, power consumption that existing medical visual acuity chart light fixture exists are big in order to overcome, portable difference, the purpose of this utility model provide a kind of simple in structure, power consumption and caloric value is low and luminosity is evenly distributed and still show in the sun new medical visual acuity chart light fixture very clearly.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of new medical visual acuity chart light fixture, the luminous body that comprises housing, surrounded by housing and be painted with visual acuity chart on its surface, the interior frame that is attached to the housing inward flange be connected luminous body on the energising device, it is characterized in that the luminous body between housing and inside casing is an Organic Light Emitting Diode.
The described luminous body that is arranged in the housing encirclement is the area source that sends the rectangle organic light emitting diode (OLED) of white light.Because the requirement of this utility model actual size, described to be arranged on the luminous body of housing in surrounding be a monoblock large scale Organic Light Emitting Diode (OLED) or be spliced by some large scale Organic Light Emitting Diodes (OLED).
Described luminous body Organic Light Emitting Diode (OLED) is made up of basic unit, anode, organic layer and negative electrode.Wherein organic layer is made up of conductive layer and emission layer.Be followed successively by according to adjacent order: basic unit, anode, conductive layer, emission layer and negative electrode.Wherein luminescent layer is an organic layer.This utility model can adopt single face luminous technics or negative electrode to adopt light tight material, reaches the effect of single face illumination.Wherein the effect of supporting whole Organic Light Emitting Diode (OLED) is played by basic unit, and the basic unit that this utility model adopts is the acrylic material that outer surface is crossed through Fuzzy processing, or the high material of other light transmittances.
Described housing is the rectangle frame body structure, and at its side one aperture is arranged, and the device of being convenient to switch on passes through.
The described interior frame that is attached to the housing inward flange be two with outer frame length short slightly and two interior frames compositions of lacking slightly with outer width of frame.
This utility model beneficial effect compared with prior art is: project organization is simple, power consumption is low, caloric value is few, portability is stronger, luminously still show very clearly evenly, in the sun.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of disassembled state shown in Figure 1.
Fig. 3 is the structural representation of another embodiment of this utility model.
The specific embodiment
Shown in accompanying drawing 1 and accompanying drawing 2, the visual acuity chart light fixture by housing 1, be attached to the inside casing 2 of housing 1 inward flange, the luminous body 3 that surrounded by housing constitutes with energising device 4 on being connected luminous body.Wherein, general aluminum alloy materials or other alloy materials of adopting of housing 1 is made, being shaped as an orthogonal framework and an aperture is arranged on its side of housing 1.The inside casing 2 that is arranged on housing 1 inward flange can adopt elastomeric material to make.Be shaped as and the outer frame length of inside casing 2 lacked and the strip short slightly with outer width of frame slightly.Be arranged on the Organic Light Emitting Diode (OLED) in the housing 1, the shape of the corresponding housing 1 of Organic Light Emitting Diode (OLED), Organic Light Emitting Diode (OLED) is a rectangle.The Organic Light Emitting Diode 3 that present embodiment adopted is a rectangle.
Shown in accompanying drawing 3, this accompanying drawing is another embodiment of the present utility model, with the variety classes visual acuity chart be plotted in the measure-alike or smaller plastic sheeting or other frivolous and transparent materials 5 of luminous body on, be fixed in luminous body 3 with inside casing 2 before, realize a-table-multi-purpose.
The embodiment that more than exemplifies only in order to conveniently to illustrate and to understand this utility model, is not breaking away from creation spirit category of the present utility model, is familiar with the various covert and modification that the personage did of this technology, still should belong in the technical solutions of the utility model protection domain.
