Description

Technical Field

[0001] The utility model belongs to the technical field of computer keyboards, and particularly relates to a desktop computer keyboard with a light transmission function. Background Art

[0002] The keyboard is the most common computer input device, which is widely used in microcomputers and various terminal devices. Computer operators input various instructions and data into the computer through the keyboard to command the computer to work. The operation status of the computer is output to the display, and the operator can conveniently communicate with the computer by using the keyboard and the display to modify, edit, control, and observe the operation of the computer. In addition to the basic function of serving as an input interface, in order to enable users to accurately press the key positions even in a poorly lit environment to avoid input errors, the illuminated keyboard came into being.

[0003] For example, the patent with the publication number CN205230898U discloses a keyboard film with a self-luminous function, which includes a keyboard film body. The keyboard film body is provided with keys that match the computer keyboard. The keys are composed of an outer layer and a tritium self-luminous glass tube inside the outer layer. The outer layer is made of silica gel. The structure of the utility model is reasonable and easy to use. By utilizing the self-luminous property of the tritium self-luminous glass tube, the entire keyboard film can emit light by itself. Its luminous brightness is high, and at the same time, the safety is also very high. Since the product technology of the tritium self-luminous glass tube is mature, its cost is relatively not very high. At the same time, the overall manufacturing process is very simple. It can ensure continuous light emission for a long time, without consuming electricity, not occupying an interface, and the brightness attenuation is not obvious. Therefore, the overall improvement is great. At the same time, a key slot is provided below the key. By using the key slot, the keyboard film body can better fit with the keyboard, and the whole is not easy to slide.

[0004] However, the applicant found that the utility model has a poor effect when adjusting the lights to achieve a running light effect, lacks a light-emitting linkage effect at the side ends of the illuminated key positions, and has insufficient aesthetics, resulting in an inability to meet the growing usage needs of users.
