    • A lens for a light emitting diode is formed with a material having a refractive index of n, and the lens includes a base, a first curved circumferential surface extending from the base, a curved center-edge surface extending from the first curved circumferential surface, and a curved centermost surface extending from the curved center-edge surface. The base includes a groove for receiving a light emitting chip therein. In the lens, a distance from a center of the base to a point of the curved center-edge surface is always shorter than the radius of curvature for the point of the curved center-edge surface. The curved centermost surface has a concave shape with respect to the base. In addition, when an obtuse angle formed between a main axis of the lens and a tangent line of a point of the curved centermost surface is A1, and an acute angle formed between a straight line linking the center of the base to the point of the curved centermost surface and the main axis of the lens is A 2, the lens satisfies the equation: A1+A2
    • 用折射率为n的材料形成用于发光二极管的透镜,透镜包括基底,从基底延伸的第一弯曲圆周表面,从第一弯曲圆周表面延伸的弯曲的中心边缘表面, 以及从弯曲的中心边缘表面延伸的弯曲的中心表面。 基座包括用于在其中接收发光芯片的凹槽。 在透镜中,从基部的中心到弯曲的中心边缘表面的点的距离总是短于弯曲的中心边缘表面的点的曲率半径。 弯曲的中心表面相对于基部具有凹形。 此外,当形成在透镜的主轴与弯曲的最中心表面的点的切线之间的钝角为A1时,并且在连接基座的中心与直线的中心的直线之间形成锐角 弯曲的最中心的表面和透镜的主轴是A 2,透镜满足等式:A1 + A2 <90 + sin-1(1 / n)。
