Luminous keyboard with light conducting plate

Abstract

A luminous keyboard with a light guide board includes: a press keys module group and a luminous module group, the luminous module group, which is located below the press keys module group, includes transparent a transparent light guide board, several luminous bodies and a reflected light board located below the light guide board; several input-light part is set on the light guide board, and the input-light part is on the light guide board to form section, the luminous body is set oppositely to the input-light part, and the generated light ray is into the light guide board by a section, the light guide board is equipped with several output-part for providing light ray to the press keys module group, each output-part includes several output-light body, the number of the output-light body at the same side of a luminary is increased according to the distance between the output-light part and the luminary. The present invention has a luminous keyboard of the light guide board which shines toward the input-light part of the light guide board by a luminous body, light has refraction or diffuse transmission when reaching to the out-put light part, the number of out-put light body included by the out-put light part, structure and position of the out-put light part can be adjusted according to requirements, and has the effect to providing uniform brightness light ray to the press keys module group.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a luminous keyboard with a light guide plate. Background technique [0002] Keyboards are very popular as an input device, and keyboards are usually used in a well-lit environment. Therefore, most keyboards themselves do not have a light-emitting function. However, sometimes it may be necessary to use the keyboard in low light or dark conditions. In order to meet this requirement, LED lights have been installed on the keyboard, and thus a luminous keyboard with a light guide plate has been produced. [0003] The existing luminous keyboard with a light guide plate uses LED lights as the luminous body, and the light is guided into the bottom of the keyboard key module through the light guide plate, and the key module is made to have a light-transmitting function, thereby realizing the luminous lighting function of the keyboard . In this way, in a weak or dark environment, the light emitted b...

Problems solved by technology

[0004] However, the existing luminous keyboard with a light guide plate transmits light from the LED light to the light guide plate, and then transmits light from the light guide plate to the button module. The structure is complicated, which is not conducive to cost reduction.
