Abstract
The invention discloses a lens capable of turning light to be horizontal. The lens capable of turning light to be horizontal is characterized in that the lens comprises a halfpace-shaped body, the body comprises an upper side face and a lower side face which are parallel to each other and are connected through an inclined plane, a first groove is formed in the upper side face and is composed of a first reflecting surface serving as the groove bottom and two second reflecting surfaces serving as the groove walls, the first reflecting surface is parallel to the side faces, and a second groove is formed in the lower side face and comprises a nonopaque surface which serves as the groove bottom and is parallel to and opposite to the first reflecting surface. The lens capable of turning light to be horizontal has a short light mixing distance, and therefore the thickness of the lens is small and the lens has good application prospect.
Description
Technical field
The present invention relates to a kind of lens, be specifically related to a kind of can the turnover light and be the lens of level.
Background technology
At present as TV direct-type backlight or panel light need than wideer lighting angle, existing TV direct-type backlight or panel light adopts the LED lens usually.Existing many LED lens can be to become 30 degree after the 120 angle fit lens of spending with original lighting angle, and the identical lens that also can see through broaden angle, are a kind of structural representation of existing lens as Fig. 1.
But all more than 28mm, its light mixing distance is obviously long for the light mixing distance of existing lens.Long light mixing distance represent the thicker reflection chamber of lens needs, and the thickness of many Yus is to TV and lamp non-good thing all, the thin direction that is only development, and prior art can not head it off.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of can the turnover light be the lens of level.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Can be the lens of level to the light turnover, it is characterized in that, comprise that one is the body of halfpace shape, described body comprises upper side and the downside that is parallel to each other, link to each other by the dip plane between upper side and the downside, described upper side offers first groove, and described first groove is by first reflecting surface as bottom land, and two second reflectings surface as cell wall are formed first reflecting surface and parallel sided; Described downside offers second groove, and described second groove comprises a transparent surface as bottom land, and described transparent surface and the described first reflecting surface parallel opposed longer sides arrange.
Aforesaid can the turnover light for the lens of level is characterized in that described first groove is trapezium structure.
Aforesaid can the turnover light for the lens of level is characterized in that described second reflecting surface is any in the transparent plane of reflection, evaporation reflecting surface, the sputter reflecting surface.
Aforesaid can the turnover light for the lens of level is characterized in that described second groove is trapezium structure.
Aforesaid can it is characterized in that the light turnover for the lens of level, on the described downside fixing feet is installed.
Usefulness of the present invention is: of the present invention can have short light mixing distance to the light turnover for the lens of level, and therefore lens thickness of the present invention is very thin, has good application prospects.
Description of drawings
Fig. 1 is a kind of structural representation of existing lens;
Fig. 2 is that the present invention can be a kind of structural representation of light turnover for the lens of level.
The implication of Reference numeral among the figure:
1, body, 2, upper side, 3, downside, 4, the dip plane, 5, first groove, 6, first reflecting surface, 7, second reflecting surface, 8, second groove, 9, transparent surface, 10, fixing feet, 11, LED matrix.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to shown in Figure 2, the present invention can be the lens of level to the light turnover, comprise that one is the body 1 of halfpace shape, body 1 comprises upper side 2 and the downside 3 that is parallel to each other, link to each other by dip plane 4 between upper side 2 and the downside 3, upper side 2 offers first groove, 5, the first grooves 5 by first reflecting surface 6 as bottom land, and two second reflectings surface 7 as cell wall are formed first reflecting surface 6 and the parallel sided; Downside 3 offers second groove, 8, the second grooves 8 and comprises a transparent surface 9 as bottom land, transparent surface 9 and the 6 parallel opposed longer sides settings of first reflecting surface.During actual motion, LED matrix 11 is placed in second groove 8 of downside 3, and the light transmission transparent surface 9 that LED matrix 11 is sent enters lens, and the light that is arranged so that of transparent surface 9 passes difficult reflection easily.Because transparent surface 9 and the 6 parallel opposed longer sides settings of first reflecting surface are therefore as long as the width of adjusting first reflecting surface 6 just can change amount of light forward.
As further improvement, first groove 5 is trapezium structure, and second groove 8 is trapezium structure.The trapezium structure manufacturing is simple.
As further improvement, second reflecting surface 7 is any in the transparent plane of reflection, evaporation reflecting surface, the sputter reflecting surface.
As further improvement,, fixing feet 10 is installed on the downside 3, fixing feet 10 is used for supporting better lens of the present invention.
Of the present invention can have short light mixing distance to the light turnover for the lens of level, and therefore lens thickness of the present invention is very thin, has good application prospects.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
