Abstract
The utility model takes advantage of the principles of refraction and random scatters, a light-emitting diode is arranged on the end plane of a marking plate, and the surrounding end planes thereof are processed into coarse limiting surfaces or coated with scattering diluent as a scattering layer. The whole marking plate is caused to generate light refraction and carry out random scatters all around with bright edge sharpness. The marking plate through the design has the advantages of bright peripheric contour, bright colors, and reserved transparency.
Description
The design belongs to a kind of identification plate of making lighting source with light emitting diode.
Red flag identification plate on " red flag " board automobile that China produces is made with red plexiglass, and daytime is bright in luster, and is ineffective at night.If peace one illuminating lamp then destroys its original transparency or brightness irregularities easily in identification plate.
The design's purpose provide a kind of can be luminous at night, brightness is even, the leaded light identification plate that not destruction marking thing is attractive in appearance again.
The design's technical scheme is as follows:
When light enters the low-refraction medium by the high index of refraction medium, and incident angle is when being higher than the angle of total reflection, and its surperficial boundary forms the leaded light transport phenomena to producing the direct reflection effect.As materials such as organic glass, epoxy resin, its angle of total reflection is about about 40 °.When incident angle is higher than 40 °, will produce the effect of reflection leaded light.
The luminous pattern that shows for needs then utilizes the principle of light scattering, and general (1) the surface working uneven surface that adopts forms random scatter; (2) in homogeneous medium, add scattering diluent.
Light emitting diode is placed the end face of identification plate, and end face is processed into rough interfaces around it, or applies scattering diluent as scattering layer.Also light emitting diode can be placed under the end face of identification plate, this end face is processed into rough interfaces with an adjacent vertical end face, or applies scattering diluent as scattering layer at above-mentioned two end faces.Its effect be make whole identification plate under the irradiation of light source, produce light refraction and around random scatter, its clear-cut is bright.
The identification plate that the design makes throws light on light emitting diode, and profile is bright all around, and the identification plate lovely luster is not lost its former transparency.
Below in conjunction with drawings and Examples the design is explained in detail.
Fig. 1 is the design's a synoptic diagram.
(1) light-emitting diode component among the figure; (2) identification plate; (3) scattering layer; (4) base; (5) decoration.
Light emitting diode (1) is connected serially to one by one equates in parallel by group with used supply voltage again, the present embodiment applied voltage is 6V.The end face of identification plate (2) is processed into rough interfaces, or applies scattering diluent as scattering layer (3) at above-mentioned end face, and light emitting diode is put into base, and an end face of identification plate places on the light emitting diode and is fixed on the base, lays ornamental strip.
Claims (1)
1, a kind of identification plate of red flag shape is characterized in that light emitting diode as lighting source places the end face of identification plate, and end face all is processed into rough interfaces around the identification plate, or applies scattering diluent on its end face.
