The light from the point source radiates to the three-dimensional space. For road lighting, we only need illumination in the next direction. Therefore, the function of the light distribution cup is to diverge the point source upwards and horizontally. The light is reflected downwards to improve lighting efficiency. The existing light distribution cups are generally trumpet-shaped, and the light forms a circular spot after the light distribution cup. The light distribution cup of the structure has a reflective wall design that is not scientific enough, and some of the light needs to pass two or more times. After the secondary reflection, the light can be emitted outside the light distribution cup, and even some of the light can not be reflected out, which causes the waste of light energy to a certain extent. Moreover, since the light distribution cup illuminates the road surface to form a circular spot, the light distribution The light reflected by the cup will partially illuminate the outside of the road, and some will overlap with the street light on the other side of the road, resulting in waste of light energy.

参看图 1和图 2，首先介绍本发明配光杯 1的结构及其制造方法进而说明本发明的配光方 法原理和采用该配光杯 1的路灯的结构。 所述的配光杯 1为一长方壳体， 杯底 11为长方形， 中央设置有光源安装孔， 于本发明中， 所述光源应该采用点光源 14， 只要其发出的光线呈朗 伯体辐射即可， 就现有技术而言， 该光源可以选用大功率 LED、钨丝灯或荧光灯等。 四面杯壁 12、 13围置成长方形的杯口， 杯底 11及杯壁 12、 13内表面皆设置有反光层， 该反光层可以 是介质膜如 + TiO Si02或 MgF2, 也可以是金属膜如镀铝、 镀银， 还可以直接在杯底 11及杯壁 12、 13打磨光滑而成， 或其他能够保证该曲面达到相当的反光效果的方法加工而得。Referring to Figures 1 and 2, the structure of the light distribution cup 1 of the present invention and a method of manufacturing the same will be first described to further explain the principle of the light distribution method of the present invention and the structure of the street lamp using the light distribution cup 1. The light distribution cup 1 is a rectangular shell, and the bottom 11 of the cup is rectangular, and a light source mounting hole is disposed in the center. In the present invention, the light source should adopt a point light source 14 as long as the light emitted by it is a Lambertian body. Radiation can be used. As in the prior art, the light source can be selected from a high power LED, a tungsten lamp or a fluorescent lamp. The four cup walls 12 and 13 are arranged in a rectangular cup mouth, and the inner surfaces of the cup bottom 11 and the cup walls 12 and 13 are provided with a light reflecting layer, which may be a dielectric film such as + TiO Si02 or MgF2 , or may be Metal film such as aluminized, silver plated, can also be directly on the bottom of the cup 11 and the cup wall 12, 13 smooth polished, or other methods that can ensure that the surface achieves a considerable reflective effect.
杯壁 12、 13的设计应该能将杯底 11中央的点光源 14发出的光线一次性反射到配光杯 1 外， 减少光线在配光杯 1多次反射造成的光能量损失， 根据斯涅尔定律通过合理的设计杯壁 12、 13与杯底 11的夹角就能做到这一点，当然为了控制反射光线的角度在一个小范围内变化， 最终控制配光杯 1投射出去的光斑的形状与光斑各区域的亮度， 最好是将杯壁 12、 13设计成 内凹弧面。 . The cup walls 12, 13 should be designed to reflect the light from the point source 14 in the center of the cup bottom 11 to the outside of the light distribution cup 1 to reduce the loss of light energy caused by multiple reflections of light in the light distribution cup 1 according to Sneek. The law can do this by properly designing the angle between the cup walls 12, 13 and the bottom 11 of the cup. Of course, in order to control the angle of the reflected light to vary within a small range, the spot light projected by the light distribution cup 1 is finally controlled. The shape and the brightness of each area of the spot are preferably designed to have concave walls on the cup walls 12, 13. .
下面以配光杯 1的长度方向的杯壁 13设计为例说明本发明配光杯 1的结构及设计原理， 参考图 3b和图 4, 以杯底 U中央即光源 14处为原点建立二维坐标， 竖直方向为 Y轴， 7J平 方向为 X轴。 首先说明主光斑的出光角度的确定， 所谓主光斑的出光角度即是直接射出配光 杯的光线与配光杯轴线（即是图 4中的 X轴）的最大夹角， 也可以说是恰好越过配光杯边缘 直接射出的那支光线与配光杯轴线的夹角。 该主光斑的出射角对光斑的形状、 亮度有很大的 影响， 在光源 14与目标照明物之间距离不变的情况下， 出射角越大， 光斑的面积也就越大， 亮度越低， 反之亦然， 设计人员可以根据实际需要运用勾股定理来确定， 例如若将本发明运 用于路灯上， 则可参考出射角为 30° , 安装高度为 12Μ， 得到宽度为 13. 8 的光斑。 The structure and design principle of the light distribution cup 1 of the present invention will be described below by taking the design of the cup wall 13 in the longitudinal direction of the light distribution cup 1. Referring to FIG. 3b and FIG. 4, the center of the cup bottom U, that is, the light source 14 is used as the origin to establish two-dimensional. Coordinates, the vertical direction is the Y axis, and the 7J flat direction is the X axis. First, the determination of the light exit angle of the main spot is described. The light exit angle of the main spot is the maximum angle between the light directly emitted from the light distribution cup and the axis of the light distribution cup (that is, the X axis in FIG. 4), which can be said to be just right. The angle between the light that is directly emitted across the edge of the light distribution cup and the axis of the light distribution cup. The exit angle of the main spot has a great influence on the shape and brightness of the spot. When the distance between the light source 14 and the target illuminator is constant, the larger the exit angle, the larger the area of the spot, and the lower the brightness. And vice versa, the designer can use the Pythagorean theorem to determine the actual needs, for example, if the present invention is applied to a street lamp, the reference angle of the exit angle is 30°, the installation height is 12Μ, and the spot having a width of 13.8 is obtained. .
再次说明反射光线出光角度的确定，所谓的反射光线的出光角度，指的是照射到配光杯 1 内壁 13上每一点的反射光线与配光杯 1轴线的夹角， 本发明中， 反射光线由于经过四面杯壁 13的反射，其组成的叠加光斑也必然是与主光斑相似的长方形，再通过设计杯壁 13的曲率控 制杯壁 13上每一点的反射光线的出光角度， 从而控制叠加光斑的形状和亮度， 让该叠加光斑 叠加到主光斑的外围光线较弱的区域，最终使得经本配光杯配光 1得到的光斑亮度比较均勾。 首先确定最大出射角， 即是照射到杯壁 13最上沿的反射光线与配光杯 1轴线的夹角， 本发明 的目的是让叠加光斑叠加到主光斑的外围光线较弱的区域， 这时， 该最大出射角应该与主光 斑的出射角相等， 这样， 照射到左边杯口边缘的光线就可被反射到主光斑最右侧的边缘； 然 后， 设计照射到杯口边缘以下的杯壁的反射光线的出射角等比缩小， 反射光线朝主光斑内部 移动， 这样， 就可以形成为主光斑由外至内补强的叠加光斑， 使得最终光斑整体亮度均匀。 The determination of the angle of the reflected light is again described. The angle of the emitted light of the reflected light refers to the angle between the reflected light that is incident on each of the inner walls 13 of the light distribution cup 1 and the axis of the light distribution cup 1. In the present invention, the reflected light is reflected. Due to the reflection of the four-cup wall 13, the superimposed spot of the composition is also a rectangle similar to the main spot, and the angle of the reflected light of each point on the wall 13 is controlled by designing the curvature of the cup wall 13, thereby controlling the superimposed spot. The shape and brightness of the superimposed light spot are superimposed on the weaker area of the main spot, and finally the brightness of the spot obtained by the light distribution of the light distribution cup is relatively uniform. Firstly, the maximum exit angle is determined, that is, the angle between the reflected light that is irradiated to the uppermost edge of the cup wall 13 and the axis of the light distribution cup 1. The purpose of the present invention is to superimpose the superimposed spot on the weaker peripheral light of the main spot. The maximum exit angle should be equal to the exit angle of the main spot so that the light that strikes the edge of the left cup can be reflected to the rightmost edge of the main spot; then, the design is illuminated to the wall below the edge of the cup. The exit angle of the reflected light is reduced in proportion, and the reflected light moves toward the inside of the main spot. Thus, the superimposed spot of the main spot from the outside to the inside can be formed, so that the overall brightness of the final spot is uniform.
实现上述反光功能的杯壁曲面其实是根据斯涅尔定律用积分迭代法计算的自由曲面， 参 考图 4， 该曲面横截面的曲线满足以下方程组： The surface of the cup wall that realizes the above-mentioned reflective function is actually a free-form surface calculated by the integral iteration method according to Snell's law. Referring to Fig. 4, the curve of the cross-section of the curved surface satisfies the following equations:
Tan(a)
y,,., = y„ + Δγ,, 本发明以杯壁 13高度（即杯口的 Υ轴坐标）为 10隨， 杯底宽度为 6固， 主光斑的出光角 度为 30° ，照射到配光杯内壁 13的反射光线的出光角度由杯口至杯底依次以 30° 〜0° 等比 渐变为例确定曲线上点的坐标， 将杯壁高度等分成一千个点积分于是有：Tan(a) y,,., = y„ + Δγ,, the height of the cup wall 13 (ie, the axis coordinate of the cup mouth) is 10, the width of the bottom of the cup is 6 solid, and the light exit angle of the main spot is 30°, and the irradiation is The light-emitting angle of the reflected light of the inner wall 13 of the light distribution cup is determined by the ratio of 30° to 0° in the order of the cup to the bottom of the cup, and the height of the wall is equally divided into one thousand points.
Ay =0.01 Ay =0.01
Δ<9 =0.03° Δ<9 =0.03°
上式中 η为数值计算的当前点， η+1为数值计算的下一点， Δχ, Ay, 为曲线在 x及 y方 向变化的微.量。 由初始条件： In the above formula, η is the current point of numerical calculation, η+1 is the next point of numerical calculation, and Δχ, Ay is the micro-quantity of the curve in the x and y directions. By initial conditions:
α,, = 0 α,, = 0
由上述的方程组可以用积分迭代的数值计算方法从下往上一直算出曲线上每个点的坐 标， 如第一点的坐标为 （3. 00577， 0. 01 ) ， 第二点的坐标为 （3. 01152， 0. 02 ) ， 第三点的 坐标为 （3. 0Γ726, 0. 03 ) ……最后一点的坐标为 （5. 77350， 10) ， 本例中是将 Υ方向分成 1000点来积分， 根据实际精确度的需要， 可以相应扩大或缩小积分点。 同理， 可以设计出 ffi 光杯宽度方向的杯壁的自由曲面。 以主光斑在配光杯宽度方向上的出光角度为 62° , 照射到 配光杯杯口.内壁 13的反射光线的出光角度由杯口至杯底依次以 62° 〜30° 等比渐变为例，最 后得到的配光杯 1安装高度在 12M时， 得到照明均匀的 40MX13. 8M的长方形光斑。 以上取点 计算可以通过计算机软件来辅助完成， 然后将各点连接成光滑曲线， 再通过计算机绘图软件 生成模型， 最后即可通过数控机床加工或精密铸造的方法生产制造。From the above equations, the coordinates of each point on the curve can be calculated from the bottom up by the numerical calculation method of the integral iteration. For example, the coordinates of the first point are (3. 00577, 0.01), and the coordinates of the second point are (3. 01152, 0. 02 ), the coordinates of the third point are (3. 0Γ726, 0. 03). The coordinates of the last point are (5. 77350, 10). In this example, the direction of the Υ is divided into 1000 points. To integrate, according to the actual accuracy, you can expand or reduce the integration point accordingly. For the same reason, the free surface of the cup wall in the width direction of the ffi light cup can be designed. The light exiting angle of the main spot in the width direction of the light distribution cup is 62°, and is irradiated to the mouth of the light distribution cup. The light exiting angle of the inner wall 13 is gradually changed from 62° to 30° by the cup mouth to the bottom of the cup. For example, when the final height of the light distribution cup 1 is 12M, a uniform circular spot of 40MX13. 8M is obtained. The calculation of the above points can be assisted by computer software, and then the points are connected into a smooth curve, and then the model is generated by computer graphics software, and finally can be manufactured by CNC machine tool processing or precision casting method.
