Embodiment
Embodiment one: combine Fig. 5 and Fig. 6 that this embodiment is described; The described a kind of Light conducting pointer of this embodiment; It comprises " own " font transparent pointer 7 and light emitting diode 8, and " own " font transparent pointer 7 has 4 flex points, and each the flex point place in " own " font transparent pointer 7 is provided with reflective surface; The head end of " own " font transparent pointer 7 is indication end 11, and the end that is somebody's turn to do " own " font transparent pointer 7 is a light incident side;
End in " own " font transparent pointer 7 is provided with the first reflective surface a,
The bottom of " own " font transparent pointer 7 ends that light emitting diode 8 is arranged on; The light that light emitting diode 8 sends is after " own " font transparent pointer 7 terminal reflective surfaces reflect, earlier after incide the indication end 11 of " own " font transparent pointer 7 after the refraction of the reflective surface at 4 flex point places.
Embodiment two: this embodiment is that the material of said " own " font transparent pointer 7 is water white PC resin to the further specifying of embodiment one described a kind of Light conducting pointer.
Embodiment three: this embodiment is further specifying embodiment one described a kind of Light conducting pointer; Two flex points in first knee of " own " font transparent pointer 7 set gradually the second reflective surface e and the 3rd reflective surface d, and two flex points in second knee of " own " font transparent pointer 7 set gradually the 4th reflective surface c and the 5th reflective surface b.
Embodiment four: this embodiment is further specifying embodiment one described a kind of Light conducting pointer; It also comprises pointer cap 12, and pointer cap 12 covers the outside surface of " own " font transparent pointer 7 between the 3rd reflective surface d and the second reflective surface e.
Because the brightness of light source is very high, light can be scurried out through the gap between liquid crystal display and the dial plate, or penetrates dazzling light from the 3rd reflective surface d, the e face of pointer, influences visual effect.Therefore, this embodiment has increased pointer cap 12, can either prevent that light from leaking, and can also increase the brightness of pointer.
Therefore the rack side wall 10 of the utility model as shown in Figure 5 sprays the berlin black colored paints, and the reflecting effect that reduces rack side wall 10 prevents to scurry light.The pointer cap 12 that between the 3rd reflective surface d and the second reflective surface e face, increases simultaneously as shown in Figure 6 prevents that light from penetrating.
Embodiment five: this embodiment is for to the further specifying of embodiment one described a kind of Light conducting pointer,
Said light emitting diode 8 is the high-power and high-luminance light emitting diode.
The lighting source of pointer is a light emitting diode, and light reflexes to the upper surface of pointer through the pointer inner first reflective surface a, the 5th reflective surface b, the 4th reflective surface c, the 3rd reflective surface d, the second reflective surface e, thereby makes whole pointer shinny.But just penetrate owing to light has passed through 5 reflectings surface in pointer inside, so light attenuation is very serious, can't reach the lighting requirement of pointer.For the brightness that makes pointer reaches request for utilization, at first to strengthen the brightness of light source, secondly be to increase the light path area, make more rays pass through the pointer conducted inside to the pointer surface.So adopt the diode of high-power and high-luminance light source to be provided for the illumination of " own " font transparent pointer.
Embodiment six: this embodiment is for to the further specifying of embodiment one described a kind of Light conducting pointer, and it also comprises pointer cap 13, and pointer cap 13 covers on the afterbody of " own " font transparent pointer 7, and said pointer cap 13 is set to white.
In order to improve the reflecting effect of pointer cap 13, pointer cap 13 is set to white.
Embodiment seven: combine Fig. 7 that this embodiment is described, this embodiment is for to the further specifying of embodiment one described a kind of Light conducting pointer,
" own " font transparent pointer 7 is by the width linear increase of head end to end.
Between the first reflective surface a to the, the five reflective surface b of " own " font transparent pointer 7 afterbodys below liquid crystal display; Can't see under the normal condition; Therefore will " own " font transparent pointer 7 by the extremely linear increase of width of end of head end; Can improve the plane of incidence of incident light like this, and then improve incident light e intensity.
Embodiment eight: this embodiment is further specifying embodiment seven described a kind of Light conducting pointers; The width of the end of " own " font transparent pointer 7 is 5 to 8 times of head end width, or the width of the end of " own " font transparent pointer 7 is 2 to 3 times of the head end width.
Embodiment nine: this embodiment is for to the further specifying of embodiment eight described a kind of Light conducting pointers, and " own " font transparent pointer 7 said first reflective surfaces are concave mirror.
The utility model is a concave mirror with the first reflective surface a, makes the first reflective surface a that certain optically focused effect arranged.Strengthen the width of the first reflective surface a simultaneously, improved the light intensity of incident light so greatly.
