Abstract

This invention relates to a light-emitting keyboard, which mainly includes a keyboard part and at least a light-emitting part. The keyboard part includes plural rows of key caps, a substrate for supporting and carrying the key caps. A movement space is formed between the key caps and the substrate for the key caps to move vertically with respect to the substrate; where the light-emitting part is installed in the movement space, and includes at least a non-light-transmissive zone and a light-transmissive zone, and projects light source on the keyboard part at a predetermined angle through the light-transmissive zone. Since the light-emitting part is installed in the movement space, the overall volume of the keyboard will not be increased. The light-emitting forms can be changed by adjusting the design allocation of the non-light-transmissive zone and the light-transmissive zone. Moreover, a track can be installed on the substrate so that the light-emitting part can be replaced in a modularized manner, making the overall structural have greater assembly flexibility.

Description

201115609 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to an illuminated keyboard, and more particularly to a design in which a modularized light-emitting portion is disposed in an existing space inside a keyboard to achieve a slim and light structure. A keyboard for the surface of the button to have a luminous effect. [Prior Art] [0002]

With the development of technology, computer systems have been widely used in various industrial fields and in ordinary life. Among them, computer systems are usually equipped with keyboard devices as command input devices. However, in response to the user's accurate determination of the relative position of each button in various environments, the corresponding command input is executed. Therefore, the market is specially designed to have i-light, or even complete darkness. . spare disk, for the input of the [0003] conventional luminous keyboard, such as the United States «patent 6, 648, sr 7, 531, 764, 7th, 589, Republic of China patent 1256009% ^ r No. 20090067153 leciucii 2^ip.4 and M352719

The nickname and the like respectively disclose a plurality of structures of the key optical module, so that the surface of the keyboard can have the effect of illuminating illumination. In the prior art, the structure of the illuminating module includes receiving an external light source to provide surface illumination of the keyboard. Light guide plate. However, the configuration of the light guide plates will increase the overall size of the keyboard, which will become more heavy and occupy space compared to the standard keyboard used in general desktop computers, and the notebook type emphasizes convenient carrying. In terms of computers, it is even more difficult to achieve a light and thin design. Secondly, with the structure of the light guide plate, in order to make the light source fully transmit in the light guide plate for the keyboard to emit light, it is necessary to configure enough 098135236 Form No. A0101 3 Page / Total 24 pages 0982060444-0 201115609 The number of light-emitting components makes the keyboard evenly illuminated. In addition, in addition to the extra space inside the keyboard to place the light-emitting components, it takes more Power is supplied to the light emitting elements. Moreover, in addition to the configuration of the light guide plate, the keyboard structure disclosed in the foregoing prior art further includes a reflective layer that reflects the light source from the light guide plate to the keyboard. Therefore, the volume of the keyboard is further increased, and the assembled structure is further improved. It is complicated and easy to cause the keyboard to be inconvenient to manufacture. [0004]

In addition, in the keyboard architecture disclosed in the above prior art, the transmission path of the light source in the light guide plate is increased, and the photons are caused to have a plurality of non-parameters and the most oxygen-emitting effect in the space inside the light guide plate. , which in turn causes attenuation of light intensity. Although Zhong Weng Weng II |^S^1226 has revealed a light guide column as a conductive disk to shorten the transmission path of the light source. However, the structure is reduced: the path that the light source needs to pass to the button, but the guide The light column is still disposed under the substrate of the intercepting button. Therefore, the keyboard is still required to have a surplus of juice, and the extra space is used to place the light guiding column, and the portion of the light guiding button position is only on the column of the column. Effectively provide light

The surface area of the source is much smaller than the total i-area of the source of the source, which in addition to increasing the cost of the materials required to fabricate the column, also creates many unnecessary sources. In addition, as disclosed in the prior art, each button must be equipped with at least one light guide column, that is, in the number of key cap configurations of a standard keyboard, at least 300 to 400 numbers must be added to the illuminated keyboard. The light guide column can achieve the effect that each key cap can effectively emit light, so 'the cost of manufacturing and the complexity of assembly are also added.

[0006] In order to achieve the above object, the present invention provides an illuminated keyboard, comprising a keyboard portion and at least one light emitting portion, the keyboard portion comprising a plurality of key caps, a substrate for carrying the key cap, and a plurality of connectors The interlocking mechanism between the keycap and the substrate forms an active space between the keycap and the substrate for the keycap to generate an up-and-down displacement stroke relative to the substrate, and the movable space is disposed in the movable space. The light-emitting portion includes at least a non-transmissive region and a predetermined angle to the light-transmitting region toward the keyboard portion. [0007] By arranging the light-emitting portion in the voice space, the structural design of the keyboard can be made. More compact, the volume does not increase; and the volume and weight occupied by the light-emitting portion, "the light-emitting key % is also greatly reduced, so that the overall weight of the raw # can be reduced at the same time. In addition, the non-transmissive region and the through-light generate partial illumination in the keyboard, so that the light source is effectively projected onto the keycap to prevent the light source from being lost in the active space.
