AI Technical Summary
In the existing luminous key structure, the backlight module light and indicator light are prone to light, resulting in poor lighting effects and the reflection of the indicator light affects the appearance of the keycap, especially when the two light colors are inconsistent, the characters and lamp holes are Mix light, and the light is reflected to the outside of the keycap.
An anti-slit light key is designed, which uses a transparent keycap and an opaque light shielding part to form one-piece. A retaining wall is provided around the light shielding part to block light scattering and light, prevent light from being reflected, and ensure that light does not reflect to the outside of the keycap.
It effectively prevents the stranding light of the backlight module light and indicator light, improves the lighting effect, and prevents light from being reflected outside the keycap, significantly improving the visual effect of the keyboard.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of keyboard keys, in particular to an anti-cross-lighting key and a keyboard. Background Art
[0002] Currently in the luminous light key structure, such as Figure 1 As shown, the backlight module light and indicator light are directly projected onto the fully transparent keycap. This structure has the following defects: (1) When the color of the backlight module light is inconsistent with the color of the indicator light of the light key, the characters closer to the light hole and the light hole will be mixed with each other, resulting in poor lighting effect; (2) When the indicator light hits the surface of the keycap, it will reflect light, causing the outside of the keycap to be very bright, which will also affect the lighting effect. Utility Model Content
[0003] Purpose of the utility model: The utility model aims to provide an anti-cross-light key and keyboard that can effectively prevent cross-light between key indicator lights and backlight modules.
[0004] Technical solution: The utility model's anti-cross-light key and keyboard include a keycap, a thin film circuit board, a base plate, a backlight module and an indicator light. The keycap has characters and indicator light holes corresponding to the indicator lights. The keycap is a transparent keycap, and a shading portion is provided around the indicator light hole on the back of the keycap.
[0005] Furthermore, the keycap and the shading portion are integrally formed by two-color molding, one shot of the two-color molding is the opaque shading portion, and the second shot is the fully transparent keycap.
[0006] Furthermore, the characters are laser engraved on the surface of the keycaps.
[0007] Furthermore, the indicator light hole is laser engraved on the keycap.
[0008] Furthermore, the shading portion is surrounded by retaining walls to further prevent the indicator light from scattering and the cross-light between the backlight module and the indicator light.
[0009] Furthermore, the shading portion is black.
[0010] A keyboard, wherein the light key of the keyboard adopts the anti-cross-light light key as described above.
[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: (1) The present invention is provided with a shading portion. When the color of the backlight module light is inconsistent with the color of the light key indicator light, the two colors of light will not mix with each other due to the blocking of the shading portion, and the lighting effect is good. (2) When the indicator light of the present invention hits the keycap, the keycap is painted black to prevent light reflection, and the light will not be reflected outside the keycap to affect the lighting effect.

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0019] Example 1
[0020] like Figure 2-5 As shown, an anti-cross-light key includes a keycap 1, a thin film circuit board 2, a base plate 3, a backlight module 4 and an indicator light 5, the keycap 1 is provided with characters 6 and an indicator light hole 7 corresponding to the indicator light 5, the keycap 1 is a transparent keycap, a shading portion 8 is provided around the indicator light hole 7 on the back of the keycap 1, the keycap 1 and the shading portion 8 are integrally formed by two-color molding, one shot of the two-color molding is an opaque shading portion 8, and the second shot is a fully transparent keycap 1, the characters 6 are laser engraved on the surface of the keycap 1, and the indicator light hole 7 is laser engraved on the keycap 1.
[0021] When the color of the backlight module lamp is inconsistent with the color of the light key indicator lamp, the lights of the two colors will not mix with each other due to the blocking of the one-shot opaque shading part 8. At the same time, when the indicator light hits the surface of the keycap, the one-shot opaque shading part 8 can prevent light reflection, so that the light of the indicator lamp 5 will not be reflected outside the keycap 1.
[0022] Example 2
[0023] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the opaque shading portion 8 is black, and the opaque shading portion 8 is surrounded by raised retaining walls 9, which more effectively prevents the cross-light and the light of the indicator light 5 from being reflected outside the keycap 1.
