Button device and light guide element

Abstract

The invention relates to a key device and a light guide component. The key device comprises a key switch, a light source, a keycap and the light guide component; the light source is adjacent to the key switch; the keycap covers the key switch and the light source; the key cap comprises a light-transmitting plate part and a side plate part; the light-transmitting plate part covers the light source; the side plate part is connected to the light-transmitting plate part, and positioned between the light-transmitting plate part and the light source; the light guide component comprises a light homogenizing plate part and a light guide plate part; the light homogenizing plate part includes a light output side, a back side and a light splitting groove; the light splitting groove is positioned in the light output side; the light output side faces the light transmitting plate part; the light guide plate part is protruded out of the back side, and projection of the light guide plate part in the light output side is partially overlapped with projection of the light splitting groove in the light output side at least; the light guide plate part includes a connection side close to the light homogenizing plate part and a light input side far from the light homogenizing plate part; and the light source is adjacent to the light input side, and the width of the connection side of the light guide plate part is greater than that of the light input side of the light guide plate part.

Description

technical field [0001] The invention relates to a key device and a light guide element, in particular to a key device and a light guide element with a luminous effect. Background technique [0002] In today's technologically advanced information age, computers have become an indispensable necessity for people. As far as the current computer is concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. When a user selects a keyboard, in addition to considering the function of the keyboard, the visual effect of the appearance of the keyboard is also valued by the user. For example, luminous keyboards have been launched on the market at present, in order to attract users by creating cool visual effects through lights. In addition, when the user uses the luminous keyboard at night or in a place with insufficient lighting, the light source provided by the luminous keyboard itself can also help the user find the keys, so as to...

Problems solved by technology

[0003] However, it is generally difficult to balance the manufacturing cost and the light uniformity of the luminous keyboards currently on the market. The reason is that if you want to improve the light uniformity of the luminous keyboards, you must increase the number of light sources, but the increase in the number of light sources will increase the brightness of the luminous keyboards. manufacturing cost

Conversely, if the number of light sources is reduced, although the manufacturing cost of the luminous keyboard can be reduced, the light uniformity of the luminous keyboard will be reduced.

Therefore, the luminous keyboards currently on the market have the problem of difficulty in balancing the manufacturing cost and the uniformity of light.
