Specific embodiment
For a better understanding of the technical solution of the present invention, the implementation that the present invention is described in detail provides with reference to the accompanying drawing
Example.
The present invention provides a kind of lampshade unit, as depicted in figs. 1 and 2, the lampshade unit generally tetragonal body, comprising:
Upper top 211, next top 213 and bottom, the upper top 211 are located at the top of the next top 213, and the bottom is located at institute
The lower section of next top 213 is stated, has sidewall portion 212 between the upper top 211 and the bottom, when lampshade unit and display screen group
When having unified, the bottom and side wall portion 212 is contacted with display screen.The upper top 211, next top 213 and the sidewall portion
212 form cavity, are provided with reflective particles in the cavity, the cavity is solid or vacuum.In the present embodiment,
Preferably, the material of the lampshade unit is polyacids rouge material, is filled between the upper top 211 and the next top 213
The more uniform reflective particles for scattering light.Random mix with polyacids rouge material of the reflective particles is arranged described
In the cavity that upper top 211 and the next top 213 and the sidewall portion 212 are formed, the reflective particles are high power minerals.
The sidewall portion 212 forms the accommodation space for accommodating illuminator 11 with the next top 213.The illuminator
11 light launched enter the accommodation space after, light by next top 213 reach reflective particles layer, described reflective
Reflective particles in granulosa are reflected and are reflexed to the accommodation space, the light after the refraction and reflection to the light
Eventually arrive at upper top 211.
Due to the characteristic of light itself, the light that illuminator inside display screen issues include the visible visible light of human eye it
It outside, further include the blue light being harmful to the human body, and visible wavelength is 400 to 700 nanometers, blue light wavelength is 400 to 480 nanometers,
Blue light wavelength is compared with visible light wave length, and the visible light and blue light are under the action of the accommodation space and the reflective particles
It is reflected and is reflected, above reflection and refracting process are the consumption to the visible light and the blue light wavelength, wavelength
The speed that shorter blue light consumes in above-mentioned refraction and reflection process is faster than visible light, thus the light of illuminator eventually by
When the upper top 211 is seen by human eye, blue light is effectively consumed, to reach the display that the lampshade unit is arranged
The brightness of screen is not soft, dazzling, the eyeshield effect of eye fatigue free long-term viewing.
On the basis of the above embodiments, in other embodiments, further, as shown in Figure 1, the upper top 211
For the plane of rectangle, the next top 213 is also the plane of rectangle, but the area of the next top 213 is less than the upper top
The central point of 211 area, the upper top 211 and the next top 213 is on the same axis.In the present embodiment, described
Upper top 211 and the next top 213 are the square of plane.The upper top 211 and square of the square-shaped planar are flat
The cavity that the next top 213 in face and sidewall portion 212 are formed is a regular square, and the reflective particles are arranged described
In square, the next top 213 forms the accommodation space for accommodating the illuminator 11, the illuminator 11 with sidewall portion 212
Launch light, the light is reflected and reflected by the reflective particles of the cavity after accommodation space scattering, makes light
It is more uniform soft and consume harmful blue light.
On the basis of the above embodiments, in other embodiments, further, as shown in attached drawing 1-2, the side wall
Portion 212 includes inner wall 2122 and outer wall 2121, between the inner wall 2122, the next top 213 and the bottom described in formation
Accommodation space, it is preferred that for the volume for increasing the accommodation space, the next top 213 or the curved surface to arch upward upwards,
The cavity, the chamber are formed between the outer wall 2121, the upper top 211, the next top 213 and the inner wall 2122
Setting reflective particles in vivo.As shown in Fig. 3, the accommodation space is for accommodating illuminator 11, the height ratio of institute's accommodation space
The height of the illuminator 11 is high, it is ensured that there is a certain distance at the top of the illuminator away from the next top 213, is conducive to
The light that illuminator 11 issues is scattered in the accommodation space, can comprehensively be entered in the cavity, the cavity
Interior reflective particles are scattered and reflect to the light, keep light more uniform soft.
On the basis of the various embodiments described above, in other embodiments, further, the outer wall of the sidewall portion 212
2121 are provided with metal coating.In the present embodiment, it is preferred that the sidewall portion 212 include four side walls, described adjacent two
The outer wall 2121 of a side wall is provided with metal coating, and coating is arranged in the two neighboring side wall of the lampshade unit, guarantees multirow
The lampshade unit combination settings of multiple row together when, the four sides of the lampshade unit is provided with metal coating.The gold
Category coating is foil, and the outer wall 2121 of the adjacent wall is provided with the foil in whole or in part.The thin gold
The light light blocking in accommodation space and reflective particles can be acted on by belonging to piece, and the optical path of the light is concentrated on through the lamp
In the accommodation space of cover unit and cavity equipped with reflective particles, the light is prevented to be spilt into other lampshade units thoroughly, increased
The brightness of the light reduces the distortion phenomenon of image.
A kind of display screen cover, as shown in figures 3-5, lampshade list described in any of the above-described technical solution including multiple lines and multiple rows
Member 21 arranges.The display screen cover 2 can be fabricated to the display of arbitrary size according to the size or actual demand of display screen 1
Screen cover.
It is provided for the embodiments of the invention a kind of lampshade unit above and display screen cover is described in detail, for this
The those skilled in the art in field, thought according to an embodiment of the present invention, have change in specific embodiments and applications
