The LED new light sources is as new application, though himself have remarkable fine quality, the application facet in lighting field replaces traditional sodium vapor lamp, and daylight lamp etc. still have its limitation and need the part of improvement.Thereby it is little such as the little light-emitting area of volume owing to led light source, and its luminous directivity also causes its irradiated area limited, increase irradiated area simultaneously so in actual illumination is used, how to change the irradiating angle of pointolite (strictness says it is facet light), thereby can remain the focus that merits attention a plane inner control light source range of exposures in different directions.Simultaneously, existing led light source has the shortcoming of light dazzle and skewness.
Thereby, be necessary to provide a kind of LED street lamp lens device of improvement, so that overcome the shortcoming and deficiency of prior art.
Summary of the invention
The purpose of this invention is to provide the good LED street lamp lens device of a kind of radiation response.
To achieve these goals, the invention provides a kind of LED street lamp lens device, comprise: pedestal, from the outstanding oval cylinder that forms of pedestal, do not give prominence to an end concave shaped ovalization hollow bulb of oval cylinder on the described pedestal, become half-cylindrical space towards described oval cylinder concave shaped in the described oval hollow bulb, the long axis direction that is axially perpendicular to described oval hollow bulb in described half-cylindrical space, described oval cylinder comprise annular sidewall and respectively and the convex surface of described annular sidewall transition adjacency glossily and concave surface between described convex surface.
The invention has the advantages that: the LED street lamp lens device has improved the distribution effect of LED pointolite widely, light source is fully used and has improved the irradiation uniformity coefficient on ground, solved the technical barrier of LED as dazzle of novel illumination source light and skewness.
Below in conjunction with accompanying drawing, describe the present invention in detail by preferred embodiment.

Embodiment
With reference now to accompanying drawing, present invention is described.
As shown in Figures 1 to 4, LED street lamp lens device 100 provided by the invention comprises that pedestal is such as rectangular susceptor 401, from the pedestal 401 outstanding oval cylinders 504 that form.Do not give prominence to an end concave shaped ovalization hollow bulb 503 of oval cylinder 504 on the described pedestal 401, the direction indents towards described oval cylinder 504 in the described oval hollow bulb 503 form half-cylindrical space 601.The long axis direction that is axially perpendicular to described oval hollow bulb 503 in described half-cylindrical space 601.In addition, a pair of oval location division 502 of outstanding formation in the described oval hollow bulb 503 is used for assisting led light source 506 (with reference to figure 4) is installed in the described half-cylindrical space 601.
Described oval cylinder 504 comprises annular sidewall 505 and respectively and a pair of convex surface 202,201 of described annular sidewall 505 smooth transition adjacency, a pair of convex surface 301 and the concave surface 101 between described a pair of convex surface 202,201.
Preferably, described LED street lamp lens device 100 adopts optical grade material PC or PMMA injection mo(u)lding.
As shown in Figure 4, in the half-cylindrical space 601 according to LED street lamp lens device 100 of the present invention led light source 506 is installed.When led light source 506 was lighted in half-cylindrical space 601, for whole LED street lamp lens device 100 of the present invention, led light source 506 was with respect to a circular arc cylinder light emitting source.
