摘要：
A lens (20) includes a light receiving surface (24) and a light emitting surface (26) opposite to the light receiving surface (24). Light emitted by a light emitting diode (30) enters the lens (20) via the light receiving surface (24) and leaves the lens (20) via the light emitting surface (26). In a coordinate system, the light receiving surface (24) satisfies an equation (1): Z S 1 = ∑ i = 1 N 1 a i X 2 i + ∑ j = 1 N 2 b j Y j , wherein a i and b j are aspheric coefficients. Key aspheric coefficients include a 1 and b 1 , and a 1 and b 1 satisfy a formula: -0.5 1 Z S 2 = ∑ i = 1 N 1 c i X 2 i + ∑ j = 1 N 2 d j Y j , wherein c i and d j are aspheric coefficients. Key aspheric coefficients include c 1 and d 1 , and c 1 and d 1 satisfy a formula: -0.3 i i
