Embodiment Construction

[0006] Concrete technical scheme of the present invention is as follows:

[0007] product structure:

[0008] The product is mainly composed of light guide frame, light source, control circuit board, EMI shielding circuit board, light guide plate, buttons, connectors and so on.

[0009] Product reinforcement features:

[0010] In order to solve the problem that the product cannot be used normally in high temperature, low temperature, vibration and other environments, in addition to the aluminum alloy frame, an EMI shielding circuit board is also specially designed. The single-sided EMI shielding circuit board makes it anti-interference better.

[0011] The light guide principle of the product:

[0012] The functional part of the product is mainly composed of light source, control circuit board, light guide plate, buttons, connectors and so on.

[0013] The buttons and light guide plate of the product are made of transparent acrylic material, which has good light guide perf...

Abstract

The invention relates to the technical field of a light guide plate, and particularly relates to a light guide system specialized for a reinforced airborne display frame and buttons. An aluminum alloy frame is adopted, and an EMI shielding circuit board is also designed especially. Anti-interference performance is enabled to be better by the one-sided EMI shielding circuit board. Light-emitting didoes (LED) are adopted to act as light sources and light sources on a control circuit board. Incident light of the light sources is incident to the light guide plate and emitted via the marks of the buttons. Visual fatigue of the eyes of people is not caused in the aspect of light color and brightness selection. The key buttons are distinguished through different colors of light. A night light function can be realized through brightness of light. A switch is controlled by the buttons. The switch is a gilded metal dome and is adhered on the circuit board by a PET thin-film through silkscreen glue so that hand feeling of the buttons of the switch is enabled to be clear. Customization of the button switch functions can be realized by the system through a matrix keyboard circuit.

Description

technical field [0001] The invention relates to the technical field of a light guide plate, in particular to a light guide system dedicated to a reinforced airborne display frame and buttons. Background technique [0002] 1. At present, domestic light guide panels are mostly light guide panels for displays, signs, surface lighting bodies, etc., with good uniformity and wide application. [0003] 2. The existing light guide plates on the market cannot meet the needs of special occasions, such as high humidity, high heat, vibration and other environments. [0004] 3. The brightness and color of the existing light guide plates on the market are easy to cause visual fatigue to people's eyes, and the key buttons are not distinguished in color, which is easy to cause mispressing. Contents of the invention [0005] Aiming at the deficiencies of the existing technology, the present invention proposes a light guide system dedicated to the reinforced airborne display frame and butt...
