Detailed Description
The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example 1:
the locally brightening automobile instrument light guide plate structure shown in fig. 1 is characterized in that: including light guide plate body 1, light inlet 2, micro-structure 3 and reflection of light thermoprint rete 4, light inlet 2 is located the one end of light guide plate body 1, micro-structure 3 is a plurality of archs and distributes on light guide plate body 1, reflection of light thermoprint rete 4 is located micro-structure 3.
In this example 1: the light inlet 2 is perpendicular to the light guide surface of the light guide plate body 1.
In this example 1: the reflective hot stamping film layer 4 is positioned at the other end of the light guide plate body 1 opposite to the light inlet 2.
In this example 1: the microstructures 3 are distributed in the area needing light guiding.
In this example 1: the reflective hot stamping film layer 4 is distributed in the area needing brightening.
In this example 1: the light guide plate body 1 is formed by optical-grade PMMA through injection molding.
In the above structure: the LED light source is LED into the light guide plate body 1 through the light inlet 2, and light rays are uniformly backlit through the microstructures 3 on the back of the light guide plate, so that the scales and the numbers of the dial are uniform; when the light is transmitted to the reflective hot stamping film layer 4, the reflective hot stamping film layer 4 can concentrate the light and is vertical to the direction of the light guide plate, so that the light guide plate can achieve local brightening; the red three-dimensional scale 31 meets the required brightness requirement through the brightening backlight, and the uniformity of the numbers on the nearby instrument panel cannot be influenced because the light in the area of the reflective hot stamping film layer 4 is perpendicular to the direction of the light guide plate.
In the above structure: set up microstructure 3 into a plurality of archs, reflection of light thermoprint rete 4 covers in the arch and connects on light guide plate body 1, and microstructure 3 arch is located between reflection of light thermoprint rete 4 and the light guide plate body 1, concentrates light and evenly jets out and can not influence the homogeneity of the figure on the near panel board through microstructure 3 arch and reflection of light thermoprint rete 4 with the perpendicular to light guide plate direction.
