Abstract
The utility model discloses a lens for an LED (light-emitting diode) polarized street lamp, relating to the technical field of lamps and lanterns, in particular to a lens for installing an LED (light-emitting diode) street lamp. The lens comprises a lens body, a light inlet surface formed by the internal concave of the lens body and a light outlet surface formed by the external convex of the lens body, wherein the light outlet surface formed by the external convex of the lens body is formed by connecting two symmetric curved surfaces; the light inlet surface formed by the internal concave of the lens body is a semi-elliptic curved surface; the long axis of the light inlet surface of the semi-elliptic curved surface is vertical to the symmetric axis of the two symmetric curved surfaces which form the light outlet surface; and the light inlet surface is closer to one curved surface of the light outlet surface. The lens has the benefits of being simple in structure and convenient to use and install, and being capable of leading light beams to irradiate in the direction leaning to a target surface, thus improving the utilization ratio of light, and leading faculae irradiating on roads to meet practical requirements better.
Description
Technical field
The utility model relates to technical field of lamps, relates in particular to a kind of lens that are used to install the LED street lamp.
Background technology
The transitional street lamps lens are symmetrical street lamp lens, when installing, need reach the road lighting effect, make the part light intensity loss simultaneously, bring inconvenience for like this installation of installation personnel by adjusting the light fixture elevation angle, strengthen workload, make that also illuminating effect is undesirable simultaneously.
The utility model content
The utility model aims to provide a kind of the need by adjusting the LED street lamp lens that the light fixture elevation angle can reach the road lighting effect at the deficiencies in the prior art.
The utility model is achieved through the following technical solutions: LED polarisation street lamp lens comprises indent forms on mirror body, the mirror body incidence surface and the external exiting surface that convexes into of mirror; The external exiting surface that convexes into of described mirror is formed by the curved surface linking of two symmetries, the incidence surface that indent forms on the described mirror body is the half elliptic curved surface, the incidence surface major axis of half elliptic curved surface is perpendicular to the symmetry axis of two symmetroids forming exiting surface, and incidence surface is close to one of them curved surface of exiting surface.
The beneficial effects of the utility model are: this scenario-frame is simple, easy to install, can make the irradiation of light deflection target face, improve the utilization rate of light, the hot spot that is radiated on the road is corresponded to actual needs more, its hot spot was symmetrical distribution along road direction in its mounting points both sides after the utility model was installed on road, be asymmetric distribution along vertical road direction, use desired irradiation distance to regulate the off-centre and the moulding of lens according to reality, the promptly actual irradiation distance that requires is far away more, the numerical value of this eccentricity of region is big more, this structure just has been equivalent to form the convex lens of an off-axis, reach the purpose that light tilts, lens are the curved surface of two symmetries, and through two semi-surfaces that the LED optical axis is distinguished, there is certain eccentric throw in its two center of circle, scioptics are regulated the light distribution of light, make that also the illumination that is radiated on the road surface is more even.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model along road direction;
Fig. 2 is the schematic cross-section of the utility model along vertical road direction.
Among the figure, 1, the mirror body; 2, incidence surface; 3, exiting surface.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
With reference to Figure 1 and Figure 2, the incidence surface 2 that mirror body 1 indent forms, the exiting surface 3 that mirror body 1 evagination forms; Exiting surface 3 is formed by the curved surface linking of two symmetries, and incidence surface 2 is the half elliptic curved surface, and incidence surface 2 major axis of half elliptic curved surface are perpendicular to the symmetry axis of two symmetroids forming exiting surface 3, and incidence surface 2 is close to exiting surface 3 one of them curved surface.
When installing, LED is installed in the mounting groove at incidence surface 2 places of indent of mirror body 1, with reference to shown in Figure 1, mirror body 1 is symmetrical distribution along the curved surface of road direction in its mounting points both sides, two semi-surfaces through the differentiation of LED optical axis, there is certain eccentric throw in its two center of circle, and scioptics are regulated the light distribution of light, makes that also the illumination that is radiated on the road surface is more even; With reference to shown in Figure 2, mirror body 1 is asymmetric distribution along vertical road direction, use desired irradiation distance to regulate the off-centre and the moulding of lens according to reality, the promptly actual irradiation distance that requires is far away more, the numerical value of this eccentricity of region is big more, this structure just has been equivalent to form the convex lens of an off-axis, reaches the purpose that light tilts.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
