Time, described operating body be formed about a visible optical effect be operated member reflection light at even tabula rasa
The optical effect that inscattering is formed, further, is formed about a visible optical effect at described operating body
The optics formed in even tabula rasa inscattering for the light of operated member reflection and the light of operating surface reflection
Effect;When operating surface is equipped with reflecting layer and even tabula rasa, it is formed about one at described operating body visible
Optical effect is that the light of operated member reflection and the light that reflected by reflecting layer are in even tabula rasa inscattering shape
The optical effect become.
Certainly, according to different situations, also should have at the visible optical effect that described operating body is formed about
Institute is different, explanation numerous to list herein.
The light efficiency equipment of the embodiment of the present invention, for a device with operating surface, described operating surface has one
Light-reflecting property, say, that be capable of reflecting light line, wherein, as it is shown in figure 1, this light efficiency equipment includes:
The even smooth unit 10 formed by the material that optical property is uneven, for arranging described operating surface 40
On;
At least one, for light unit 20, covers described even light for being formed above described even smooth unit 10
The photosphere 30 of unit.Here, so-called covering is not offered as the two needs contact, it is merely represented in vertical direction
On, photosphere has overlapping part with even smooth unit.
It is to say, this at least one confession light unit, for forming a photosphere above described operating surface,
Described photosphere and described operating surface do not have intersection point, and at least some of light of described photosphere is entered described light
The operating body of layer is reflected into described even smooth unit, enters the light of even smooth unit at described even smooth unit

Reach described reflecting layer, the described visible optical effect of rear formation under the reflection in described reflecting layer, due to
The reflectance in this reflecting layer is higher, so brightness is higher, optical effect becomes apparent from.
During it is found that do not have reflecting layer and/or even smooth unit on operating surface, only operating surface enters one
Step reflection is entered the light of the operating body reflection of described photosphere, and its optical effect is poor, and adds reflecting layer
Afterwards, owing to the reflectance in reflecting layer is higher, for operating surface, more light is had to enter
Human eye, so optical effect becomes apparent from (brightness is higher), but now may be the brightest,
And in one direction may luminance range, optical effect is the most uneven, if adding even light
Unit, due to the scattering process of even smooth unit, now optical effect is softer, and owing to being scattering,
