The combination of the light-emitting diode and the lens is a method for improving the illumination efficiency and effectively converting the light effect, and using the basic principle of light: refraction and reflection, the light source of the high-power light source of the light-emitting diode is converted into a soft and uniform light. Hook J < ,,, '叨. Generally, the light-emitting diode lens can be mostly divided into a cup shape or a hemispherical form. After the light is emitted from the light-emitting diode, it is emitted through two lenses. The cup-shaped light-emitting diode lens is a full-reflection effect on the side of the body, so that the light illuminates the uniform illumination range upwards, and the light-emitting two-segment U-group of the hemisphere is reflected by the curvature of the sphere. The effect is that the light is directed 'up' and 'aggregated' to obtain a uniform illumination range. Although these designs can effectively change the light output of the light-emitting diodes, they can be uniformly illuminated in the fixed area of the illumination area.

In addition, the 'side surface of the cup and the surface of the hemisphere are mostly smooth design', but when the human eye is directly viewed from the same angle of view, only a fixed area of light illuminates the viewing angle to cause a visually bright block. These defects make the existing light-emitting diode lens provide uniform light and illumination, but still cannot make the light-emitting diode become a lighting fixture that can be directly viewed by the human eye.

More comfortable and even. [Embodiment] In order to make your reviewer understand the content of this creation, please refer to the following description. Referring to Figure 1, it is a three-dimensional appearance of the preferred embodiment of the present invention. As shown in the figure, the improved structure of the LED lens provided by the present invention has a body i which is a truncated cone and exhibits axis symmetry with a central axis 2, and the cone a of the body i A light entrance surface 1 又 is formed to allow light to enter the body 1 through the light entrance surface and to refract when entering the body 丨. The cone bottom of the body 1 is formed with a light-emitting surface 12 for allowing light to exit the body via the light-emitting surface 12 to provide illumination and the like. An optical surface 丨4 is formed on the sidewall of the body 1. The optical curved surface 描述4 describes the shape of the side of the cone of the body 1 such as curvature, curvature, height of the vertebral body, etc., and provides an improved structure of the illuminating diode lens. The main light dry effect. The improved structure of the LED lens is characterized in that the light incident surface 10 of the body 1 is bundled and formed at a first divergence point 100 ' and the first divergence point is located at the central axis 2 The position is such that the first divergence point 100 is located on the path of the direct light so that the light is deflected from the first divergence point 100 into the body 1 to cause refraction, reducing the amount of light entering the body 1 by the straight line. Further, the optical curved surface 14 is formed with a multi-region reflective structure 140, whereby light rays entering the body i from the light incident surface 1 are uniformly distributed through the multi-region reflective structure 140, and are emitted from the light-emitting surface 12, thereby avoiding a large area. Bright area. The multi-region reflective structure 140 f is a plurality of mesh structures 1401. The single and uncovered appearances of the mesh structures may be quadrilateral or hexagonal. In this embodiment, the mesh appearance is a quadrilateral. The cone tops of i are adjacent to each other 8 M432143, and the bottom of the body 1 is arranged such that the edges of the mesh structures 形成4〇ι form a ray from the cone top of the body 1 to the bottom of the cone, and the central axis The heart line 2 is a square of increasing and increasing size of a plurality of concentric circles of the center, and the side profiles of the mesh structures 14〇1 are straight lines or smooth curves to provide different light reflection effects. Referring to Figures 2a to 2d, there are shown cross-sectional views of different aspects of the first embodiment of the present invention. As shown in the figure, the side profiles of the grid structures 为4〇ι are smooth curves that protrude outward, and are connected to each other to form the multi-region reflecting structure 14〇 which is entirely wavy. The curvature and appearance of the light-incident surface 10 are matched with the optical curved surface 14 to provide an optimal illumination effect. Due to the nature of the light, the total reflection phenomenon does not occur when the light-diffusing medium enters the optically dense medium. Therefore, the design at this end can be effective and easy to enhance the effect of refracting light without increasing the complexity of optical design due to light reflection. As discussed in the light path of the lens entering the lens, as shown in FIG. 2a, the slope of the light incident surface 1〇 causes the light entering the body 1. to generate a large angle deflection in the central region of the light incident surface. In the edge region of the light incident surface, a small angle is generated, so that the amount of light irradiated to the optical curved surface 14 is increased as shown in FIG. 2b, and the slope of the light incident surface 10 is fixed so that the light enters the body directly. The light of 1 is evenly deflected toward the fixed angle. The deflection angle of the light is smaller than that of the central region of the 2a image.

In addition, as shown in Fig. 2d, the light-incident surface of the light-incident surface is formed by the slope of the segment and the surface of the curved surface, so that the light entering the body 1 is refracted to produce a more subtle change in locality. The dice effect is more refined. In addition to the above-described implementation, the shape and optical design of the light-incident surface 10 can be subdivided into a plurality of segments of curvature, or each portion produces a high or low 'local structure of the bumps' to increase or decrease the refractive effect of the light, with the optical curved surface 14 Designed for optimal lighting and visual experience. Please refer to the 3a '3b diagram together for the two schematic diagrams of the multi-regional reflection structure. As shown in the figure, the multi-region reflective structure 140 is a plurality of mesh structures 14 〇 1 'the side profiles of each of the mesh structures 1401 are smooth curved surfaces, as shown in the figure, the mesh structures 1401 The side profile is a smooth curved surface that protrudes outward. Since each of the mesh structures 14〇1 has a similar curved surface, when the naked eye is facing the light exiting surface 1 2 in a direction perpendicular to the light exiting surface 12, the light is The light is reflected from one side of the grid structure 14 〇1 to the same viewing angle, as indicated by the light in the figure. Therefore, the whole face is not presented on the human eye, but is placed on the small glossy surface of the mesh structure 1401. It should be noted that since the multi-region reflective structure 140 is configured to reflect light to the light-emitting surface 12*, the effect of total light reflection needs to be considered in design, and the curved surfaces of each of the mesh structures 1 401 The incident angle of the light is made larger than the critical angle of total reflection (critical angle θ ε = sinusoidal inverse function sinll/D of the lens refractive index D)) to reduce the amount of light escaping from the optical curved surface 14 to dissipate. In addition, in order to enhance the function of the reflection, the amount of light reflected to the light-emitting surface 12 is increased. The multi-region reflective structure 140 further includes a reflective layer 16 disposed outside the body 1 and covering only the optical curved surface 14 and the nets. In the lattice structure 1401, the reflective layer 16 can be coated with a material having a high reflectivity such as metal, PP or PET, so that light entering the body 1 can be prevented from passing through the optical surface 14 from the body 1 and in turn contacting the reflective layer 16. Reflected to the light exit surface 12, thereby increasing the amount of light to enhance the brightness. Similarly, when the light exit surface 1 2 is viewed sideways, a portion of the mesh structures 14 01 is also reflected to the viewing angle. Such a design not only eliminates the bright and dark areas of the entire surface but enhances the soft feeling when the naked eye directly gazes 'and because the optical curved surface 14 is changed by the multi-region reflective structure 140, thereby enabling reflection to the same viewing angle. The area throughout the optical surface 14 is not limited to only one area, which makes the visually more uniform. And the side profile of the grid structure 1 4 01 is a smooth curved surface that is concave inward, which has a similar and opposite effect to the convex structure of the 3a figure, both of which are at the same angle of view. As seen, the positions of the bright areas of the grid structures 14 〇 1 are opposite, and the angle of view of the light exit surface 丨 2 is visually recognized as an example (the light of M432143 -->j in the figure), and the light reflection area of the 3a picture The grid structure 1401 is away from the light exit surface 12, and the light reflection area in Fig. 3b is such that the grid structure 14〇1 is close to the light exit surface 12. Although the concave and convex views of the two mesh structures 1 4 〇 i are different from the same viewing angle, the light-emitting diode lens can be provided to improve the uniform light structure. Please also refer to Figures 4 and 5 for a perspective view and a cross-sectional view of the second embodiment of the present invention. As shown in the figure, the light-emitting surface i 2 of the improved structure of the light-emitting diode is constricted and formed at a second divergence point 120 to enhance the effect of light refraction in the central region, and the second divergent point 120 is located. The central axis position is set relative to the first divergence point 100. When the light is contacted by the body 丄 via the multi-region reflective structure 〇4〇 (the grid structure 1401 is recessed toward the body 1 as shown in the figure), the second light surface 12 will be produced. The second refraction causes the line to deflect again. Since the light-incident surface 1〇 and the optical surface Η have the effect of uniform light, the structure of the light-emitting surface 12 can be corrected for the effect of the light-emitting, and the light effect of the local or the system is improved. To make the light distribution more uniform, it is worth mentioning that the multi-region reflection structure 140 1 is not in the same mesh structure of the same pattern structure, and may also be composed of irregular polygons, and the multi-region reflection structure 140 is Irregular design makes the reflected light path more irregular, thus improving the uniform output of light. Please also refer to Figure 6 for the implementation of the second creation. 12 as shown in the figure, the 'lighting_mounting member 3 is disposed in the body: the body-improved structure further comprises at least one or both, so as to facilitate the mounting of the __ The light-emitting diode is improved two: the light-emitting diode light source 4' is not shown). , and the structure of the damper is used in the lighting (see also the 7a and m.. in the figure, which is the three-dimensional appearance and section of the creation of the second example). The creation also provides different hands & to achieve astigmatism uniformity, as shown in the figure, the illuminating-polar lens improved structure has a truncated cone-shaped body 7: central axis. Line 2 is axisymmetric 'the body 7 The cone top recess is formed with a light incident surface 7°' for receiving the light emitting diode light source 4 and allowing light to enter the body 7 via the light incident surface 70. The cone bottom of the body 7 is formed with a light exit surface 72. The light-emitting surface 72 is convergently formed at a second divergence point 72〇, and the second divergence point 720 is located at the central axis line 2, and the light is directly incident into the body 7 through the slave. The second divergence point 7 2 〇 is deflected to cause refraction, and the light of the straight line is emitted from the body 7. The side wall of the body 7 is an optical curved surface 74 to describe the tapered side curvature, curvature, and vertebra of the body 7. a shape such as a height of the body, and characterized in that a multi-region is formed on the optical curved surface 74 The radiation structure 740 is configured to uniformly distribute the light entering the body 7 from the light incident surface 70 through the multi-region reflective structure 740 from the light exit surface 72 to avoid a bright area of a large area. The multi-region reflective structure 740 is a plurality of mesh structures 7401.

In addition, the light having a small refraction angle from the light incident surface 7 to the light exit surface 72 is transmitted through the light exit surface 72 to the second divergence point 720, so that the light is refracted toward the edge and the light is made More evenly distributed, and in order to strengthen the anti The function of the shot is such that the amount of light reflected to the light-emitting surface 72 is increased. The improved structure of the light-emitting diode lens further comprises a reflective layer 76, which is disposed outside the body 1 with a material having high reflectivity such as metal, PP or PET and only The optical curved surface 74 and the mesh structure 7401 are covered to reduce the amount of light that is refracted from the optical curved surface 74, and then reflected to the light-emitting surface 72' by contacting the reflective layer 76, thereby increasing the amount of light.

The present invention provides different means for different light-emitting type one-pole light source 4" The effect of uniform astigmatism is as shown in the figure. The improved structure of the LED lens also has a truncated cone-shaped body 8 which is axisymmetric with a central axis 2", and the cone of the body 8 is concave.

The side surface of the body 8 is an optical curved surface 84 for describing the shape of the tapered side curvature, the curved piece, the height of the vertebral body, and the like, and is characterized in that a multi-region reflective structure 840 is formed on the optical curved surface 84. According to the multi-region reflective structure 840, the light entering the body 8 from the light-incident surface 8 is distributed by the light-emitting surface 82.

The multi-region reflective structure 84 is a plurality of mesh structures 8401. In this embodiment, each of the mesh structures 840 1 is another hexagonal shape that is adjacent to each other to become a feather-like shape. Deploying to the bottom of the cone, and the side of each of the grid structures 840 1 is a straight line or a smooth curve. When the light-emitting diode light source 4′′ is low in brightness or composed of two or more light-emitting diodes, The light diverging from the light-emitting diode light source 4" is not concentrated on a bright spot, so the central region of the mother must provide a astigmatism structure to illuminate the curved or straight line of the multi-region reflective structure 84 in the mesh structure 84〇1. The edges create reflections that spread the light to different viewing angles, avoiding the situation where the single-view produces a bright area. In order to reduce the amount of light refracting the body 8 from the optical curved surface 84, the amount of light reflected to the light-emitting surface 82 is increased. The improved structure of the light-emitting diode lens further includes a reflective layer 86 disposed outside the body 1 and The optical curved surface 84 and the mesh structure 84〇1 are coated with a material having a high reflectivity such as metal, PP or PET, thereby increasing the amount of light to enhance the brightness. 15 M432143 In summary, in the implementation of this creation, the light of the mirror can be refracted to different angles, which greatly reduces the high brightness of the polar point source and the illumination of the edge. The light emitted by the lens exhibits uniform brightness over the entire surface. The converging design not only effectively improves the angle of light refraction, but also has a significant effect. The multi-zone of the side of the lens can make the light of the same viewing angle be visually uncomfortable by distributing the different bright surfaces of the whole film, and the light is more uniform. However, the above-mentioned ones are only for the purpose of limiting the scope of this creation, and are also within the scope of this case; therefore, those who are familiar with equivalent or easy changes, without departing from this The equal changes and repairs made under the scope of the creation shall be within the scope of the patent. The effect will be provided by the light-emitting surface, which is provided on the light-incident surface, and is provided in a convenient and uniform salt-reflecting area, so that the illumination is better and the other transformations are made by the spirit of the technology.
