Multicolor luminous word key

Abstract

The invention discloses a multicolor luminous key comprising a key cap, a light guide area, a multicolor layer and a light source, in which, the key cap has a front surface and a back surface, the front surface is provided with marks, the back surface is provided with a cavity; the light guide area is arranged around the marks; the multicolor layer is arranged in the back surface of the key cap; the light source is arranged under the key cap. When the light source irradiates upwards from the lower direction of the key cap, the light source scatters outwards from the multicolor layer and the light guide area to enable the periphery of the marks to send out color light, thereby not only being convenient for people to use under dark or weak light environment, but also increasing beautiful effect of the key.

Description

technical field [0001] The invention relates to a luminous key, in particular to a key with multi-color uniform luminous effect. Background technique [0002] At present, when using the keys of electronic products, users need to use external light sources to identify the marks on the keys before they can use the keys to control the electronic products accordingly. However, in low-light or dark environments, users often cannot see the The mark on the key is cleared and the operation cannot be performed. In order to operate the keys in a low-light or no-light environment, people add a backlight light source under the key cap, such as the luminous keys of a common mobile phone. The position is scattered outward to help users identify the corresponding mark, but generally only monochromatic light can be emitted, and the light-emitting position is relatively single, so as far as the user's visual experience is concerned, what the existing light-emitting buttons present is a kind...

In order to operate the keys in a low-light or no-light environment, people add a backlight light source under the key cap, such as the luminous keys of a common mobile phone. The position is scattered outward to help users identify the corresponding mark, but generally only monochromatic light can be emitted, and the light-emitting position is relatively single, so as far as the user's visual experience is concerned, what the existing light-emitting buttons present is a kind of monotony visual effects of

[0003] In order to make the keycaps emit colored light, some people use multi-color LEDs as illuminants, which can make the keys emit colored lights of different colors, but the cost of multi-color LEDs is much higher than that of ordinary white light, and the cost is relatively high. not easy to promote
