Example two
The embodiment is further explained and supplemented based on the technical scheme described in the first embodiment.
The utility model provides a floated control panel, includes control panel body 1, with continuous central processing unit of electrical apparatus, a plurality of position inductors and a plurality of light source module 3 that link to each other with central processing unit respectively, wherein:

The control panel body 1 is provided with a slot 2, and the light source module 3 corresponds to the slot 2 in position, so that a user can see light emitted by the light source module 3 through the slot 2.
The difference between this embodiment and the technical solution described in the first embodiment is that, in the latter, because the light is directly emitted into human eyes, there is a situation that the eyes are injured due to too high light intensity, and in order to make the user safer to use and more experience, as shown in fig. 3, this embodiment adopts the following technical solution:
first, the control panel body 1 is a transparent panel, and can ensure light transmission, and meanwhile, a part of light is reflected, thereby reducing the intensity of the light to a certain extent.
Secondly, light source module 3 sets up in any side of control panel body 1 for the light that light source module 3 sent passes control panel body 1 from the side, and light and the face contained angle of control panel body 1 be less than 90. As shown in fig. 4, the above scheme makes the light not directly enter the eye, but when the light-transmitting control panel body 1 is used as a medium to travel, the light encounters the slot 2, because the light passes through the slot 2 and the control panel body 1 as different media, and the light is reflected or refracted under the condition that the critical position of the light and the control panel body 1 is not vertical incidence, so that the intensity of the light is dispersed, the user can also see the light reflected or refracted by the slot 2 without directly aiming at the light source, and the common shapes of the slot 2 include a V-shaped slot (as shown in fig. 4), a square slot, a U-shaped slot, and the like. Light is not only softer like this, and in the sense organ of vision moreover, people can regard as the light of directly sending from fluting 2, and comfort level and experience feel are all better than directly seeing light source module 3.
It should be noted that, for the square control panel body 1, to achieve the best display effect, the light source may be disposed on the upper side or the lower side of the control panel body 1, so that the light direction is relatively longitudinal; or on the left or right side of the control panel body 1, so that the light direction is relatively transverse. The position of concrete setting needs to be decided according to the direction of fluting 2, specifically, is to guarantee that the direction of light and fluting 2's direction is nonparallel, and its contained angle is close more perpendicularly, and the more of reflected light, the better is visual effect.
EXAMPLE III
The present embodiment is further explained and supplemented based on the technical solutions described in the first embodiment and the second embodiment.
The utility model provides a floated control panel, includes control panel body 1, with continuous central processing unit of electrical apparatus, a plurality of position inductors and a plurality of light source module 3 that link to each other with central processing unit respectively, wherein: the position sensor is used for detecting the position of the hand of the user corresponding to the control panel body 1.

In order to ensure that light can be seen from various angles, the embodiment adopts the following technical scheme:
as shown in fig. 5, a plurality of reflective bumps 4 are disposed on the slot 2, so that the slot 2 forms diffuse reflection to the light. Through the setting of reflection bump 4, make fluting 2 no longer smooth/circular arc, because the shape, angle, the size of reflection bump 4 are all random, when light (show with the line of arrow in fig. 4 and 5) passes through these reflection bump 4, the reflection of light is also random, still because control panel body 1 uses transparent material, so reflection bump 4 also can make the refraction of optic fibre expense transmission random direction, just so can not appear like the regular one-way forward of light of 4 kind, from the whole, equivalent to fluting 2 has carried out diffuse reflection to the light, light can go forward to all directions, make the user can see fluting 2 luminous no matter in that direction. In the process, the grooving 2 can be polished by sand paper and other equipment, and the reflective salient points 4 can be formed on the transparent control panel body 1 due to the fact that sand grains on the sand paper are unevenly distributed and the polishing direction is random. It should be noted that fig. 5 ignores the light refraction phenomenon of the transparent material in order to make the composition clear and not disordered, and it can be seen that only all listed light rays are reflected to be almost non-parallel light paths, and according to the light refraction theorem, even if the refraction phenomenon of light passing through different media is considered for each light ray in fig. 5, the advancing direction of the light ray is more randomized and ranged.
In some embodiments of the present invention, the top angle of the reflection bump 4 is rounded by rounding, so as to further improve the diffusion effect of diffuse reflection. In production, the acrylic plate can be heated at a proper temperature to be slightly melted, and then the sharp top angle is wrapped.
