Description

A kind of structure of light-conducting type signal display apparatus

Technical field

The utility model relates to a kind of structure of signal display apparatus, specifically is a kind of its structure of signal display apparatus that has light-guide device.

Background technology

As display units above the equipment such as instrument, instrument, mostly existing signal display apparatus is mechanical type and photo-electric, and wherein, photo-electric has mainly been utilized the indicator lamp of shades of colour, combination, and the information of needs caution is shown that it is obvious that it warns effect.Yet in many occasions, this type signal is given mechanical, stiff, the not enough hommization of people, dazzling sensation, less than more abundant effects and variation.

The utility model content

To the deficiency of above traditional electro-optical display device, the utility model proposes a kind of structure of light-conducting type signal display apparatus, and its technical scheme is following:

A kind of structure of light-conducting type signal display apparatus, it comprises:

A solid-state light conductor, a reflecting surface, a visible face at top and the plane of incidence of side bottom having; And

The display light source that has the directionality bright dipping, at least one is positioned at said plane of incidence surface external position; Its exiting surface is inner towards said light conductor in said plane of incidence position;

Wherein, its bounce technique of said reflecting surface is to inner towards said light conductor, and comprises the part of said its bright dipping projection of display light source exiting surface; Said visible face is positioned at outside the panel of the equipment of being shown.

As the preferred person of present technique scheme, can aspect as follows, have improvement:

In one preferred embodiment, said reflecting surface has the diffuse reflective structure with light output diffuse reflection to the said light conductor inside of said display light source.

In one preferred embodiment, the light output minute surface that said reflecting surface has said display light source reflexes to the inner minute surface catoptric arrangement of said light conductor.

In one preferred embodiment, said reflecting surface has the total reflection structure with light output total reflection to the said light conductor inside of said display light source.

In one preferred embodiment, said display light source is a light emitting diode.

In one preferred embodiment, said display light source is the comprehensive light source that has the directionality optical treatment.

In one preferred embodiment, said display light source comprises vary in color a plurality of.In one preferred embodiment, said visible face surface has can emergent ray be overflow throws the frosting form of handling.

In one preferred embodiment, said visible face comprises by displayable literal of illumination or pattern.

The beneficial effect that the utility model brings is:

1. reflecting surface can be adjusted the beam distribution by the visible face outgoing to a great extent, and therefore, no matter the exiting surface form of display light source why, the display effect that it is final can be improved to a great extent, obtains abundant effects.

2. what the reflecting surface handled of diffuse reflection can make visible face goes out light effect processings that be optimized, lifting angle of visibility.

3. the visible face of diffuse transmission processing can further improve the visual effect of visible face, makes it more even.

4. the display light source form of separating with visible face makes form that display effect is not subject to display light source itself basically and goes out light effect, therefore, has goodish applicability, can satisfy under the same display effect, and the replacement of multiple display light source is used.

Description of drawings

Embodiment is described further the utility model below in conjunction with accompanying drawing:

Fig. 1 is the utility model embodiment one sketch map;

Fig. 2 is the utility model embodiment two sketch mapes;

Fig. 3 is the utility model embodiment three sketch mapes.

The specific embodiment

Embodiment one:

Like Fig. 1, the utility model embodiment one sketch map; Light conductor 10 is the flat entity of transparent PC material, and its bottom has the reflecting surface 11 of a minute surface, and the top has the visible face 13 that is used to export demonstration light; Between reflecting surface 11 and visible face 13; Light conductor 10 itself has the plane of incidence 12 of side; One side external position of this plane of incidence 12 has the display light source 20 of LED form; And the exiting surface 21 of display light source 20 comprises from exiting surface 21 some 11 in face that is reflected of ray cast via light conductor 10 in the inside of this position towards light conductor 10.

Display light source 20 is LED forms, so its directionality is very strong, the light that is sent by this light source exiting surface 21 all gets into light conductor 10 inside from the plane of incidence 12 basically; Thereby except a part is directly penetrated the visible face 13 by light conductor 10 refraction, another part 11 reflections of face that are reflected are again via light conductor 10 inside, from visible face 13 outgoing.So, can pass through the suitable adjusting of reflecting surface 11 and, visible face 13 positive observers can in time be observed all from visible face 13 outgoing from the emergent light of display light source 20; Simultaneously, as required, reflecting surface 11 can be adjusted the beam distribution by visible face 13 outgoing to a great extent; Therefore, no matter exiting surface 21 forms of display light source 20 are why, the display effect that it is final; Embodied by visible face 13, can be improved to a great extent, obtained abundant effects; In addition, visible face 13 outer surfaces also have the micro-structural that diffuse transmission is handled, and make that the light of visible face 13 is further improved, and it is even and soft to seem.

Embodiment two:

Like Fig. 2, the utility model embodiment two sketch mapes; Different with embodiment one is, the reflecting surface 11 that takes shape in light conductor 10 bottoms has the diffuse reflection surface structure, and simultaneously, the display light source 10 of side 12 positions is not a led light source, but has the discharge lamp 23 of reflector 24.

Discharge lamp 23 was the light source of isotropic directivity originally, and through the processing of reflector 24, the beam angle of its exiting surface 21 just has tangible directionality; Simultaneously; Via the inner light of light conductor 10, the adjustment that under the diffuse reflection of reflecting surface 11 is handled, is optimized, thus the beam angle of seeing from visible face 13 can be bigger; Thereby can compare evenly, promote the angle of visibility of whole visible face 13.In addition, also has the pattern that indicates information warning on the visible face 13.

Embodiment three:

Like Fig. 3, the utility model embodiment three sketch mapes.Different with embodiment one is that the reflecting surface 11 of light conductor 10 is the surfaces through polishing, makes it can have good total reflection performance; The display light source 20 of side 12 positions remains led light source; But have a plurality ofly, and vary in color, so; Can obtain via the later effect of each display light source 20 secondary colour from the visible face 13 of light conductor 10; For example adopt multiple color/colour mixture to indicate temperature, watt level or the like has performance quite intuitively.Simultaneously, visible by above embodiment, the form that display light source separates with visible face; Make form that display effect is not subject to display light source 20 itself basically and go out light effect, therefore, have goodish applicability; Can satisfy under the same display effect, the replacement of multiple display light source is used.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
