New description: [New technology field] This creation is related to the field of light-emitting diode lenses, especially regarding the use of the principle of concentrating to enhance the light intensity, and can evenly illuminate the effect and present a kind of rectangular illumination area. Polarized street light optical lens. [Prior Art] Light Emitting Diode (LED) has the advantages of low voltage, low power consumption, and long life compared to conventional light sources. Therefore, LEDs have been widely used in various related fields where light sources are required in today's life. For example, a backlight module for a display, an indicator light source, a general lighting device, and the like. Among them, LED has a particularly significant energy-saving and power-saving advantage, so its practicality is particularly important in the most widely used lighting purposes. For example, the application of LED light sources to the illumination of nighttime streetlights is an example of this. However, compared with the conventional light source, the light diverging angle of the light-emitting diode is small, so that when the light is applied to the illumination of the street lamp, the central brightness is too concentrated, which causes the brightness of the vicinity of the street lamp to be different from the distance, and cannot be effective. Provide street lighting in a uniform manner. In this regard, it is advantageous to use the secondary optics principle to change the optical properties projected by the LEDs to provide optimum illumination for a variety of different conditions of use. For example, the streetlights on both sides need to be able to present at least the illumination effect of the rectangular-like area, which can be provided in the parallel road direction and the M395836 vertical road direction. Therefore, how to effectively improve the projection intensity, projection range, and illumination uniformity of the LED light source is a problem that the practitioners in the field are eager to improve. In view of this, the creator feels that he has tried his best to study and 'has been working hard on the industry's accumulated experience. For the current general trend of street lamps and the length and width of roads, they have been proposed and approved. In the Taiwan Patent No. M380480 patent, the effect of offsetting the illumination area is obtained by using the asymmetric lens structure characteristic to make the LED light source pass through the lens. The creator further developed a polarized streetlight optical lens that can enhance the light intensity by using the principle of concentrating, and can uniformly illuminate the effect and present a kind of rectangular illumination area, and completely illuminate the LED light source on the road surface. In order to strengthen the night driving and the safety of passers-by, it can meet the environmental protection requirements of both energy saving and carbon saving. [New content] In view of the above problems, the purpose of the present invention is to provide a polarized streetlight optical lens that utilizes the one-human optical principle to further change the optical characteristics of the LED. In this way, it is used to enhance the intensity of light irradiation, uniformity, and effect, and presents a special effect of a kind of rectangular illumination area, so as to enhance the environmental protection requirements of energy saving and carbon saving while strengthening night driving and safety of passers-by. . In order to achieve the above objectives, the present invention proposes a polarized streetlight optical lens having a lens body comprising: a projection curved surface, which is used by M395836 to enable the reviewing committee to clearly understand the content of the creation. Please see. Please refer to Figures 1, 2, 3 and 4, which are the exterior views of the original creation, the side view of the creation on the X-Z plane, the top view on the χ·γ plane, and the cross-sectional view on the Υ-Ζ plane. In view of the above, the present invention provides a polarized street light optical lens having a lens body - including a projection curved surface 10 and a bottom surface 12. The projection Φ surface 1 〇 is composed of a plurality of surface points 1 〇 2 . Using geometric principles, the lines are formed by points, and the lines form the basic concept of the surface, and the curved surface points 102 on the projected curved surface 10 are listed to further define curves and curved surfaces, and given the number of such curved surface points 102 The smoothness of the pupil surface 10 will be determined. There are a number of ways in which the curve and surface can be created by using the surface points 102 in engineering, and are not described in detail herein. Mainly by using the concept of smooth joints, it is ensured that the curve is connected at a given curved point 1〇2, so that the tangent is continuous and the curvature of the curve is continuous, and then the projected curved surface 10 is constructed. - The polarized streetlight optical lens provided by this creation uses a two-dimensional coordinate to represent each surface point 1 〇 2 in its space. Wherein the projection surface 1〇 edge forms a reference surface 1〇4, and the reference surface 1〇4 has a long axis 1〇6 and a short axis 1〇8, and the long axis 1〇6 is in the x-axis direction, The short axis 108 is in the direction of the x-axis, (1 is a unit coordinate length, and the intersection of the long axis and the short axis 1〇8 is a three-dimensional coordinate origin, wherein the curved points 102 are on the χ-ζ coordinate plane, Each point (χ'ζ) is (〇, 7 29), U 84 7 is called, (3 97 7 28), 7 M395836 (6.18, 6.81), (7.76, 6.03), (9.04, 4.88), (9.80, 3.59), (1〇·〇9, 2.00), (1〇〇9,14〇), (ι〇〇9 〇); on the χ-γ coordinate plane, each point (x, y) is (〇 , 6 49), ' (1.70, 6.62) ' (3.62, 6.94) . (5.47, 6.91) ' (7.20, 6.45) ^ (8.54, 5.54), (9.49, 4.08), (9.96, 2.50), (10 .〇9,i.〇4), (1 0·02,0) and (0,-5.06), (UU 32), (2 66,_5 66), (4.03,-5.68), (5.47,- 5.44), (6.67, -4, 97), (7.77, -4.23), (8.58, -3.39), (9.23, -2.42), (9.70, -1.36), (ι0·01〇); On the ζ coordinate plane, each point (yz) is (〇7 28), (0.99, 7.32) ) ^ (2.19, 7.20) . (3.40, 6.84) ' (4.60, 6.18) > (5.37, 5.52), (5.99, 4.76), (6.53, 3.81), (6.88, 2.78) ' (6.89, 0.88), (6.72, 〇) and (〇, 7.28), (-0.84, 7.14), (·1·68, 6.90), (-2.47, 6.55), (·3.24, 6.10), (-4.07 ,5·43), (-4.6 5,4.8 0)' (-5.19,4.02)> (.5.70, 2.40)' (-5.48,0.90).

Therefore, the surface points 1 The distance between 〇2 and χ, γ, and ζ is the multiplication of the corresponding (x, y, z) coordinates by the unit coordinate length d, for example, (xd, yd, zd). The distances from 102 to γ, γ, and z are respectively allowed to have a relative error p, and ·d/2〇SpSd/2〇. Therefore, the relative error range β′ is also the scope of rights claimed by the author: The bottom surface 12 and the edge of the reference surface 1〇4 are interconnected to form the lens body, and the center of the bottom surface 12 is recessed to form an accommodating chamber 122 for accommodating the LED. The lens body ι is based on a Υ-Ζ surface and is only mirror-symmetrical to the χ-axis direction. The polarized streetlight optical lens is fixed to the upper side with respect to the LED substrate by the 8 M395836 type fastener. The effect of the creation is to use the aspherical wide illumination angle design of the polarized streetlight optical lens to make the light source of the light-emitting diode pass through the polarized streetlight optical lens to produce a refraction effect, so that the illumination area of the light projection roughly corresponds to the length. The axis direction datum surface is symmetrical on both sides. In addition, the asymmetric lens body structure is used to achieve the effect of the partial light mode, so that the overall illumination area is shifted, and the road surface is more effectively and appropriately illuminated. According to this, the LED light source can be effectively irradiated to the road surface completely, and the use of the LED lamp can achieve the energy-saving, carbon-saving and environmental protection requirements, and can enhance the safety of driving at night and using passers-by. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, it is equivalent to the equivalent or easy change of the technology. Equal servant changes and modifications made without departing from the spirit and scope of this creation shall be covered by the scope of this creation.
