Specifically, in this embodiment, the light emission angle in the longitudinal direction (that is, the direction of the C90°-C270° cross-section of the light distribution device) is diffused to 120-140°, that is, the emission angle is 120-140°, reducing the LED The concentration of light intensity in the center of the light source 3 can achieve precise light distribution with large spacing and avoid glare.
参照图4，进一步作为优选的实施方式，所述弧线的曲线路径满足第一公式，所述第一公式为：Referring to Fig. 4, further as a preferred embodiment, the curved path of the arc satisfies the first formula, and the first formula is:
Y1＝-7E-05x4+0.003x3-0.0329x2-0.0058x+1.0449Y1＝-7E-05x 4 +0.003x 3 -0.0329x 2 -0.0058x+1.0449
其中Y1代表纵坐标，横坐标的取值范围为0<X<10。Among them, Y1 represents the ordinate, and the value range of the abscissa is 0<X<10.
