Description

Illuminated keyboard with radiant contour

The invention relates to an illuminated keyboard, in particular to an illuminated keyboard which can emit light from the side edge of the keyboard and has a brilliance profile.

In order to make the symbols on the keyboard key caps clearly recognizable in the low light environment, and at the same time satisfy the new generation of users' preference for trendy technology, there is a question of the keyboard that can emit various dazzling colors. The light is projected onto the keycap through the light guide plate or the light-emitting diode inside the keyboard, so that the light is seen out from the symbol on the keyboard key cap and is perceived by the user.

A conventional illuminating keyboard, as shown in US Patent Publication No. 2010/0103644, includes an outer casing and a keyboard portion, the outer casing including a top case and a bottom case which are assembled to each other to form a space for the content, the keyboard portion including a substrate carrying a plurality of pressing members, a light guiding space is formed between the substrate and the bottom case, and a light emitting unit for providing light is provided in the light guiding space, wherein a height of the light guiding space is a distance from the light emitting unit The reduction enables the illuminated keyboard to emit light uniformly.

Although the conventional illuminated keyboard can meet the needs of consumers, in the live scene of the video game, in addition to the sound and light effects of the game, the keyboard and mouse used by the video game players are also eye-catching. Focus, and the effect of the traditional illuminated keyboard on the keycap is not unusual. Therefore, in order to further attract the attention of the audience, some manufacturers install a light-transmissive strip on the side edge of the keyboard, so that the light reflected from the keyboard is The light-transmissive strips are emitted to the outside, so that the side edges of the illuminated keyboard can also emit brilliant colors.

A conventional keyboard capable of emitting light at a side edge, as shown in the new model No. M423298 of the Republic of China, includes an upper case, a lower case and a transparent frame, the upper case and the lower case defining an opening, the transparent frame passing through the opening The first surface of the transparent frame is a rough surface, and the first surface is corresponding to the opening, and the light passing through the first surface is scattered by the first surface. The ambient light is incident on the inside of the keyboard through the light-transmissive strip, and is reflected by the internal components of the keyboard, and then emitted out of the keyboard through the light-transmissive strip, but the emitted light usually reflects the image of the internal structure of the keyboard. In order to overcome the aforementioned drawbacks, the aforementioned patent mainly scatters the light emitted from the inside of the keyboard through the rough surface, so that the light does not reflect the image of the internal structure of the keyboard.

However, in order to enable the light-transmissive strip to emit brilliant light, it is necessary to inject light into the light-transmissive strip by an ambient light source of various colors or an illumination source inside the keyboard, and the light-transmissive strip then emits light. When light enters the light-transmissive strip, some of the light is reflected and cannot be absorbed by the light-transmissive strip, causing the brightness of the light to decrease. In addition, in order to enable the keyboard to emit light from the side edge, the keyboard still needs to be additionally provided with the light-transmissive strip. This method not only increases the manufacturing process and cost, but also the light-transmitting strip may fall off from the keyboard after being impacted by external force.

The main purpose of the present invention is to make full use of the existing components of the illuminated keyboard, so that the illuminated keyboard can emit light from the side edges without additionally providing a light-transmissive strip.
