Lens and LED using the lens to achieve homogeneous illumination |
摘要 |
A lens and an LED using the lens to achieve homogeneous illumination include a region. The region around the optical axis of a lens is designed to be concave and form a divergent surface. The upper surface of the lens is a continuous curved surface to diverge the high-intensity light emitted by the LED in the vicinity of the optical axis through refractions. Therefore, the LED can homogeneously illuminate a larger area.
