摘要
我们设计了一种新的全内反射结构，用于产生LED透镜，该透镜可以在两个垂直方向上产生小发散角的矩形光束，用于光学制导系统。利用1 mm × 1 mm的LED光源，可以将水平方向的发散角控制在8°左右的小值，垂直方向的发散角也可以控制在7°左右，光学收集效率高于0.83。研制成功后，证明了该透镜适用于光学制导系统。
LED Lens for Rectangular Beam with Small Divergence Angles
We have designed a new TIR(Total Internal Reflection) structure for generating an LED lens which can produce a rectangular beam with small divergence angle in two perpendicular directions for an optical guidance system. The lens can control the divergence angle in the horizontal direction to be a small value of about 8° with a 1 mm × 1 mm LED source, also in the vertical direction it can be about 7°, with optical collection efficiency higher than 0.83. After the lens is manufactured, the work demonstrates that the lens is suitable for an optical guidance system.
