Button device and light guide element

Abstract

The invention discloses a keypress apparatus and a light-conducting element. The keypress apparatus includes a keypress switch, a light source, a key cap and a light-conducting element. The light source is close to the keypress switch. The key cap covers the keypress switch and the light source. The key cap includes a light-transmitting plate part and a side plate part. The side plate part is connected to the light-transmitting plate part and surrounds the light source. The light-conducting element is disposed between the light-transmitting plate part and the light source. The light-conducting element includes an even light plate part and a light introducing part. The even light plate part has a light-emitting surface and a back surface. The light-emitting surface faces the light-transparent plate part of the key cap. The light introducing plate part has one connecting surface and one light incident surface which are in opposite arrangement. The connecting surface is connected to the back surface of the even light plate part and is connected to one side edge of the back surface. The light source is close to the light incident surface side of the light introducing part, and the connecting surface of the light introducing plate part is longer than the light incident surface of the light introducing plate part in length.

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 luminous effects. 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 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.
