Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, Lai Zucheng more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1, with reference to Fig. 1 and Fig. 2, a kind of light conducting plate structure with curved surface, including light conducting plate body, the leaded light
Plate ontology includes leading tabula rasa 100 and auxiliary light guide plate 200, and the left edge 300 of the leading tabula rasa 100 is light source entrance, institute
Leading tabula rasa 100 is stated with curvature portion and planar section, the downside of the leading tabula rasa 100 is equipped with the first site matrix
110, the lower section of curvature portion, the upper side and curvature portion of the auxiliary light guide plate 200 is arranged in the auxiliary light guide plate 200
Downside fitting, it is described auxiliary light guide plate 200 downside and adjoining planar segment downside it is in the same plane, institute
The downside for stating auxiliary light guide plate 200 is equipped with the second site matrix 210, and the refractive index of the auxiliary light guide plate 200 is less than leaded light
The refractive index of plate.
When light guide plate work, light source is entered from left edge 300, and in the planar section of leading tabula rasa 100, light is all-trans
It penetrates, when light gets to the site in the first site matrix 110, which becomes to scatter, and scattering light is by dominating tabula rasa 100
Upper side projects.It is not then whole in curvature portion due to the change of angle in the curvature portion of leading tabula rasa 100
Light is all totally reflected as in planar section, and a part of light passes through the site in the first site matrix 110 from leading tabula rasa 100
Upper side projects, and another part light can then be projected from the downside of curvature portion.In order to recycle this part light, therefore, in curved surface
Partial downside setting auxiliary light guide plate 200, the downside of the auxiliary light guide plate 200 are equipped with the second site matrix 210, should
Site matrix can be scattered to through the light come, to change the direction of light, return it into leading tabula rasa 100, and from leading
The upper side of tabula rasa 100 projects.So that the illuminance of curvature portion and planar section is balanced.
The application passes through auxiliary leaded light by the lower section setting auxiliary light guide plate 200 of the curvature portion in leading tabula rasa 100
Plate 200 recycles the light transmitted from curvature portion, so that curvature portion illumination deficiency is compensated, so that entire light guide plate
The curvature portion of ontology and the uniform illumination of planar section, so that realizing has the light guide plate of curved surface.
As optimization, the lateral distance x of two sites of the arbitrary neighborhood in first site matrix 110 is equal.
As optimization, the lateral distance y of two sites of the arbitrary neighborhood in second site matrix 210 is equal.
As optimization, the site in first site matrix 110 and the site in the second site matrix 210 are mutually wrong
It opens.More light can be recycled in this way.
With reference to Fig. 2, as optimization, the site diameter in first site matrix 110 is from left edge 300 to right hand edge
400 incrementally increase.The range that light source is in contact with leading tabula rasa 100 has certain luminous flux, and when luminous flux is wanted to extend to
It, just must be continual into leading tabula rasa 100 using site as the approach of transmission light entirely when leading 100 upper side of tabula rasa
Diffusion.Meanwhile light can generate certain light decay process with the distance of luminous range in transmit process, it is remoter apart from light source
A possibility that causing light decay is bigger, and luminous flux also can decreases with distance, so from light source remote position, site
Increase, compensates for light caused light decay phenomenon in transmit process, make the uniformity of area source and brightness more lasting.
As optimization, the minimum site diameter in first site matrix 110 is 0.516mm, first site square
Site diameter in battle array 110 is incrementally increased from left edge 300 to right hand edge 400 with the variable quantity of 0.002mm-0.003mm.
As optimization, site diameter in first site matrix 110 from left edge 300 to right hand edge 400 with
The variable quantity of 0.003mm incrementally increases.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
