Patent Number: 8016451 
Title: Variable Spot Size Lenses and Lighting Systems 
Abstract:

Improved lighting devices and methods are provided. In many embodiments, the devices and methods provide the capability to change a spot of light projected onto a target surface. In other embodiments, the devices and methods are fixed-focus. In one embodiment a lens can have a lens body with anterior and posterior surfaces. The anterior surface can be adapted to receive light from a light source. The posterior surface can have a central portion and a peripheral portion. Some of the light from the light source can pass through the lens body and exit the central portion of the posterior surface via refraction. Some of the light from the light source can pass through the lens body and exit the peripheral portion of the posterior surface via both refraction and reflection at various surfaces of the lens.
