Abstract

The invention provides a key illumination device and an application method thereof. The device comprises a key, a light tube, an ultra-thin switch, a support board and a flexible printed circuit board, wherein the flexible printed circuit board is bent, and two ends of the flexible printed circuit board are fixed on two sides of the support board respectively; the light tube is fixed at one end, deviating from an equipment base, of the flexible printed circuit board, and the ultra-thin switch is arranged at the other end of the flexible printed circuit board; first positioning holes matched with first positioning columns are formed in the flexible printed circuit board; the key is arranged on the outer side of the light tube in a sleeving manner and fixedly connected with the flexible printed circuit board. According to the key illumination device and the application method thereof, the ultra-thin switch and the light tube are fixed on the two sides of the support board through the flexible printed circuit board, so that the pressing and illuminating actions of the key are not mutually influenced; the key is arranged on one side, where the light tube is bonded, of the support board, and the light tube is accommodated in the key, thereby uniformly illuminating the key; the positioning holes formed in the flexible printed circuit board replace a long guide positioning structure, so that positioning of the key and the ultra-thin switch is realized, and the overall thickness of the key illumination device is reduced.

Description

technical field [0001] The present invention relates to the technical field of button lighting, and more specifically, to a button lighting device and an application method thereof. Background technique [0002] The physical buttons of smart terminals such as mobile phones, PADs, and car navigators are divided into two types according to their thickness, one is ultra-thin buttons, and the other is thick buttons. A smart terminal with ultra-thin buttons has a thickness of about 12mm; a smart terminal with thick buttons has a thickness of about 23mm. [0003] For the ultra-thin key, in the prior art application, an ultra-thin switch is generally used to control the lamp tube to illuminate the ultra-thin key. figure 1 shows the structure of the ultra-thin key lighting device, from figure 1 It can be seen that the ultra-thin switch 3 and the lamp tube 4 are arranged on the printed circuit board 17, the lamp tube 4 is arranged in four directions around the ultra-thin switch 3, ...
