Description
Technical field
The utility model relates to the good light guide plate of digital camera of a kind of colour rendering, belongs to electronic accessory parts field.
Background technology
Light guide plate is mainly used in the liquid crystal display of electronic product, as notebook computer, LCD TV, digital camera etc., existing light guide plate is made up of exiting surface, incidence surface and reflectance coating, and light is directly penetrated by exiting surface via after reflecting film reflects, and colour rendering is not fine.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, provides the light guide plate of digital camera that a kind of colour rendering is good.
The utility model solves the technical scheme that its technical matters adopts: the light guide plate of digital camera that a kind of colour rendering is good, comprise exiting surface, incidence surface and reflectance coating, described exiting surface is positioned at incidence surface top, and it is parallel with incidence surface, described reflectance coating is positioned at bottom incidence surface, described incidence surface is provided with lamp hole, and described exiting surface is provided with pit and ring groove, is coated with phosphor powder layer at described exiting surface skin.
Described pit is positioned at the central authorities of exiting surface, and described ring groove is the center of circle with pit, is looped around on exiting surface.
The cross section of described pit and ring groove is wide at the top and narrow at the bottom trapezoidal.
Described lamp hole is evenly distributed on pit and annular groove bottom.
Beneficial effect: this product is coated with phosphor powder layer at exiting surface skin, and light penetrates through phosphor powder layer, and colour rendering is better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The light guide plate of digital camera that a kind of colour rendering is as shown in Figure 1, 2 good, comprise exiting surface 1, incidence surface 2 and reflectance coating 3, described exiting surface 1 is positioned at incidence surface 2 top, and it is parallel with incidence surface 2, described reflectance coating 3 is positioned at bottom incidence surface 2, described incidence surface 2 is provided with lamp hole 4, described exiting surface 1 is provided with pit 5 and ring groove 6, described pit 5 is positioned at the central authorities of exiting surface 1, described ring groove 6 with pit 5 for the center of circle, be looped around on exiting surface 1, the cross section of pit 5 and ring groove 6 is wide at the top and narrow at the bottom trapezoidal.Described lamp hole 4 is evenly distributed on bottom pit 5 and ring groove 6.
Phosphor powder layer 7 is coated with at described exiting surface 1 skin.
Incidence surface 2 is provided with lamp hole 4, is arranged on by light source in lamp hole 4, and change side-light type is direct-injection type, the direct directive exiting surface of light, greatly improves light utilization rate; Pit 5 and ring groove 6 combine, can make light disperse evenly; The cross section of pit 5 and ring groove 6 is wide at the top and narrow at the bottom trapezoidal, can play better optically focused effect.
Should be appreciated that specific embodiment described above only for explaining the utility model, and be not used in restriction the utility model.Still be among protection domain of the present utility model by spirit institute's apparent change of extending out of the present utility model or change.
