    • A lens assembly includes a platform having an incident surface and a projection surface on opposite surfaces thereof. Wire holes are formed to the bottom side along a longer axis of the incident surface for wiring. A cut is formed around the incident surface for receiving waterproof ring. The incident surface has a main oval-shaped concave surface. Two symmetric oval-shaped lateral concave surfaces are formed to front two lateral sides of the main oval-shaped concave surface. The projection surface is formed by a plurality of continuous oval-shaped convex surfaces and discontinuous oval-shaped convex surfaces. Two symmetric vertical planes are formed to two lateral sides of the projection surface. The lens assembly capable of receiving LED larger than 10 mm has good distribution of a transverse maximum intensity of light occurring between ±50 to ±60 degrees and a vertical maximum intensity of light occurring between ±30 to ±40 degrees.
    • 透镜组件包括具有入射表面的平台和在其相对表面上的投影表面。 线孔沿着用于布线的入射表面的较长轴线的底侧形成。 在入射表面周围形成切口以接收防水环。 入射面具有主椭圆形的凹面。 在主椭圆形凹面的前两侧形成两个对称的椭圆形侧凹面。 突起表面由多个连续的椭圆形凸面和不连续的椭圆形凸面形成。 两个对称的垂直平面形成在投影表面的两个侧面。 能够接收大于10mm的LED的透镜组件具有在±50至±60度之间发生的横向最大光强度与在±30至±40度之间发生的垂直最大光强度的良好分布。
