Embodiment Construction

[0040] The technical content and detailed description of the relevant invention are now described as follows in conjunction with the accompanying drawings:

[0041] figure 1 and figure 2 They are respectively the schematic diagram of the first light guiding structure of the present invention and figure 1 schematic diagram of the front view. As shown in the figure, the light guide structure of the present invention includes: a light guide plate 1 and a plurality of light emitting components 2 . The light generated by the light-emitting component 2 is projected upwards, and then the light is concentrated and refracted on the key (not shown in the figure) by a plurality of light-guiding particles 15 on the light-guiding plate 1 . In this picture, there are 4 light-emitting components.

[0042] The light guide plate 1 has a plurality of light guide areas 11, the light guide area 11 has a central light guide circle 12, the periphery of the central light guide circle 12 has a...

Abstract

A light guide structure is arranged inside a keyboard and includes a light guide plate and a plurality of lighting components. The light guide plate has a plurality of light guide areas, which are provided with a central light guide circle. And the central light guide circle extends outwards with a plurality of light guide rings. The light guide area and the adjacent light guide area have at least one light guide ring in intersected connection. In addition, the central light guide circle and the plurality of light guide rings are provided with a plurality of arc light guide particles respectively. The light guide plate is arranged with the lighting components therebelow. And the light components correspond with the central point position of the central light guide circle. When the lighting components are lightened up, the light ray will project to the light guide plate from down to up and is refracted by the light guide particles on the light guide plate to corresponding keys, which will have light transmission display effect with figures or graphs on the key surface.

Description

technical field [0001] The invention relates to a light guiding structure, in particular to a light guiding structure with a light concentrating effect. Background technique [0002] Nowadays, many small electronic products such as portable mobile phones, personal digital assistants, satellite navigation systems and other related electronic devices have become indispensable electronic products in daily life. These electronic products all have a small keyboard structure, which allows users to input data or execute various functions of the electronic product. [0003] In the keyboard structure of these electronic devices, there is a hidden backlight. In the case of no light source, the backlight provides the keyboard backlight effect, and the light of the backlight can penetrate through the surface of the key to show the surface of the key. Numbers or patterns, when the user operates the keys on the keyboard, the situation of pressing the wrong key will not occur. [0004] I...
