Description

Illuminated keyboard with glowing keycaps

technical field

The utility model relates to a luminous keyboard with luminous keycaps, in particular to a luminous keyboard in which a shading sheet is stacked on the bearing surface of a pressing part to shield the light projected to the bearing surface and limit the light to be projected only from the pressing surface and the connecting surface .

Background technique

Whether it is a desktop computer or a notebook computer, the keyboard device is the most important command input device in the computer system, and its design focuses on allowing users to input commands comfortably and accurately. In a low-light environment, a user who is not familiar with the symbols or text configurations on the keycaps will immediately face the dilemma of being unable to input commands accurately. Therefore, in order to allow users to clearly identify the keycaps in a low-light environment Symbols or characters on the keyboard, there are many kinds of luminous keyboards coming out now, such as U.S. No. 6284988, 6322229, 6199996, 6554442, 6179432, Taiwan Bulletin No. 509955, 465777, 535385, 438035, 570235, 468833, 516671. Both of these documents mention a kind of luminous keyboard that uses a built-in luminous sheet to project a light source, so that the user can still accurately judge the characters on the keyboard under insufficient light.

However, in the above-mentioned cases, the keycaps, elastic bodies, and interlocking mechanisms are mostly made of light-transmitting materials, or the keycaps are designed to be non-transparent, and then the characters and symbols on the keycaps are used as light-transmitting, so that the light-emitting elements A whole-chip light projection is produced, so that the keyboard presents a uniform light projection pattern. However, this light emission pattern will cause troubles for users in use. In the case of insufficient light, the uniform lighting of the keyboard will cause its overall brightness to be too strong. Anyway, it is not good for the user to see, so that the character symbols on each keycap cannot be clearly recognized, even if only the character symbol casts light or is blocked. However, the problem of difficult identification will still be caused by the interference of light emitted by adjacent keycaps. For users who are not familiar with the configuration of keyboard character symbols, the problem cannot be solved specifically.

For this reason, the inventor has proposed a luminous keyboard with non-uniform light projection, such as No. I230957, Taiwan, a shielding element is set between the keycap and the light emitting element, so that the shielding element is a light-transmitting area at the position of the individual keycap, The position below the adjacent keycaps, which are not individual keycaps, is used as a non-transparent area to form non-uniform light projection, hoping to solve the problem that the overall brightness of the keyboard is too strong due to uniform light projection in conventional luminous keyboards, which is unfavorable for viewing. In addition, today's keyboard structure is more pursuing light and thin. In addition to changing the thickness of the keyboard structure, there are thinner keyboards without interlocking mechanisms or elastic bodies. Therefore, the inventors are eager to find another light-emitting keyboard structure It is expected to be thinner.
