The utility model consists of pitch lines forming figures, characters, symbols or patterns on a reflection board surface, and each pitch line consists of multi-section line segments, and the number, the size and the form of the multi-section line are not restrained, therefore, the utility model is provided with value and beauty similar to a vacuum fluorescent tube displayer, and the utility model has the advantages that the manufacturing process is simplified, the quality is improved, the material is saved, the cost is reduced, etc.

Description

The light emitting diode indicator structure

Technical field

The utility model relates to a kind of light emitting diode indicator structure, particularly a kind of structure with similar vacuum fluorescence tube display display effect that replaces.

Background technology

At small-sized literal and the graphic alphanumeric display sold on the market numerous species is arranged at present, as vacuum fluorescence tube display (vacuum fluorescent display, be called for short VFD) be one of them, because it goes out electronics by emission of cathode in transparent vacuum tank, process grid accelerating impact is to anode, utilize the nucleophobic impact of fluorophor on the anode and luminous, belong to the display module of self-lighting, this display module is widely used on products such as the higher household electrical appliances of surcharge, sound equipment and instrument and equipment.

The structure of this vacuum fluorescence tube display, as Fig. 1 and Fig. 2, it is to be provided with panel 60 on above-mentioned vacuum fluorescence tube display (VFD) body, and includes assemblies such as fluorophor 62, glass substrate 63, insulation course 64, anode 65, filament 66, grid 67 and lead 68 at body;

Though the demonstration of above-mentioned vacuum fluorescence tube display can increase the effect on the visual perception, still, material cost height such as its parts, and not only time-consuming but also consume the worker on manufacturing process, defect rate is higher, and production efficiency is also not high simultaneously, therefore, costs an arm and a leg and difficult popularizing.

Secondly, on using, the vacuum fluorescence tube display of this small-sized literal and pattern has shortcomings such as life-span weak point, bad mechanical strength, brightness decay quick (cause brightness disproportionation, dimness, identification bad etc. problem) and cost height.

Seeing also Fig. 3, is the synoptic diagram of traditional reflecting plate, wherein is provided with a light emitting diode 50 in reflecting plate 1a, and this light-emitting diode chip for backlight unit 50 is to be located on the substrate 80 by elargol 70, then is formed with the nodel line 90 of numeral on reflecting plate 1a face.

Summary of the invention

The purpose of this utility model, be to provide a structure with similar vacuum fluorescence tube display display effect, it is the nodel line that is formed with numeral, literal, symbol or figure on the reflecting plate face, each nodel line is formed by the more piece line segment, what, size of its more piece line are all not limited with form, so as to the display effect and the printer belt of replacement vacuum fluorescence tube display.

Another purpose of the present utility model, be to provide one to have the sense of worth of similar vacuum fluorescence tube display and structure attractive in appearance, because this light emitting diode indicator does not have shortcomings such as short, bad mechanical strength of the life-span of vacuum fluorescence tube display and brightness decay is quick, and can simplify manufacturing course; Save material, reduce cost, and reduce characteristics such as producing defect rate and lifting product quality.

For realizing the purpose of this utility model, we provide a kind of light emitting diode indicator structure, comprise reflecting plate, luminescence component in the reflecting plate, and the nodel line that shows different digital, literal, symbol or figure on the reflecting plate, wherein, each nodel line of different digital, literal, symbol or figure is formed by the more piece line segment on this reflecting plate.

Described light emitting diode indicator structure, its described more piece line segment is formed directly on the reflecting plate, and forms the knothole of printing opacity.

Described light emitting diode indicator structure, its described more piece line segment is sticked on the reflecting plate face by a printer belt, and forms knothole.

Described light emitting diode indicator structure, its described luminescence component are led lighting chip or the light emitting diode through encapsulating.

Described light emitting diode indicator structure, its described light emitting diode through encapsulation is a surface adhesion type light-emitting diode.

In sum, by structural improvement of the present utility model, have following characteristics:

1. has the sense of worth of similar vacuum fluorescence tube display (VFD) and attractive in appearance;

2. simplification manufacturing course;

3. saving material;

4. reduce cost;

5. reduce the product defect rate;

6. lifting product quality.

In order to illustrate further feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended icon only for reference with the explanation usefulness, be not to be used for the utility model is limited.
