Description
Technical field
The utility model relates to lens technologies field, particularly relates to a kind of cup-shaped spreadlight lens.
Background technology
Lens are optical elements made from transparency material, in fields such as astronomy, military affairs, traffic, medical science, art, play an important role.
Together with LED lens are generally closely connected with LED lamp, it contributes to promote the light extraction efficiency of LED lamp, the optical system of the optical field distribution of change LED lamp.
The hot spot that most of ornamental shot-light irradiates is at present for circular or oval, and the area of irradiation is comparatively limited, and brightness is also inadequate, and owing to being circular or oval hot spot, luminous energy major part has all been wasted, and optical artistic effect is also just had a greatly reduced quality.And the structure of the spreadlight lens of prior art is comparatively complicated, manufacture craft is correspondingly also complicated, and the bad control of its polarizing angle.
Summary of the invention
The purpose of this utility model be to avoid weak point of the prior art and provide a kind of simple in structure, manufacture craft is also simple, and the efficiency of light energy utilization is high, polarizing angle holds manageable cup-shaped spreadlight lens.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cup-shaped spreadlight lens is provided, comprise cup-shaped lens body and light out part, light out part comprises upper surface, in the utility model, the upper surface of light out part is provided with a plurality of raised lines parallel to each other, and the cross section of raised line comprises long inclined side, arc limit and short inclined side, and the one end on He Hu limit, long lopsided one end joins; the other end on arc limit and short lopsided one end join, and the long lopsided other end is all connected with cup-shaped lens body with the short lopsided other end.
Wherein, the angle of long inclined side and short inclined side extended line is 90 degree.
Wherein, raised line is distributed in a side of the upper surface of light out part.
Wherein, the area of raised line distributed areas accounts for 1/2nd of upper surface area.
Wherein, raised line is distributed in the upper surface of whole light out part.
Wherein, the long inclined side of raised line and the corner dimension of short inclined side extended line reduce to both sides gradually from the centre of the upper surface of light out part.
The beneficial effects of the utility model: the utility model is set to a plurality of raised lines parallel to each other by the upper surface of light out part, the cross section of raised line comprises long inclined side, arc limit and short inclined side, the one end on He Hu limit, long lopsided one end joins; the other end on arc limit and short lopsided one end join; the long lopsided other end is all connected with cup-shaped lens body with the short lopsided other end; simple in structure, manufacture craft is also simple, and the efficiency of light energy utilization is high, polarizing angle is easily controlled.
Accompanying drawing explanation

The specific embodiment
With the following Examples the utility model is further described.
embodiment 1.
A kind of cup-shaped spreadlight lens of the present embodiment, as depicted in figs. 1 and 2, comprise cup-shaped lens body 4 and light out part, light out part comprises upper surface, in the utility model, the upper surface of light out part is provided with a plurality of raised lines parallel to each other, the cross section of raised line comprises long inclined side 1, arc limit 3 and short inclined side 2, the one end on the He Hu limit, one end 3 of long inclined side 1 joins; one end of the other end on arc limit 3 and short inclined side 2 joins, and the other end of the other end of long inclined side 1 and short inclined side 2 is all connected with cup-shaped lens body 4.
Wherein, the angle of long inclined side 1 and short inclined side 2 extended lines is 90 degree.The angle of long inclined side 1 and short inclined side 2 extended lines can arrange according to actual needs, and the inclined plane of long inclined side 1 correspondence is mainly used in polarisation, and the inclined plane of short inclined side 2 correspondences is mainly used in supporting the inclined plane for polarisation.
Wherein, raised line is distributed in a side of the upper surface of light out part.
And the area of raised line distributed areas accounts for 1/2nd of upper surface area.The quantity of raised line can arrange according to actual needs.
Fig. 3 is the index path of the present embodiment.
Of the present utility model simple in structure, manufacture craft is also simple, and the efficiency of light energy utilization is high, polarizing angle is easily controlled.
A kind of cup-shaped spreadlight lens of the present embodiment, other knots are enough identical with embodiment 1, and difference is: as shown in Figure 4 and Figure 5, raised line is distributed in the upper surface of whole light out part.The angle of the long inclined side 1 of raised line and short inclined side 2 extended lines reduces to both sides gradually from the centre of the upper surface of light out part.Can make the utilization rate of luminous energy higher, light-struck scope is larger.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
