  • LED lens array optic with a highly uniform illumination pattern
    Patent number: 8210723
    Abstract: An LED (light emitting diode) illumination device that can generate a uniform light output illumination pattern. The illumination source includes an array of LEDs. Forward of the LEDs is an array of negative lens surfaces. At a distance from the LED the width W of the lens and the spacing D between the LEDs enhances creating the uniform light output illumination pattern. The negative lens surface can be non-symmetric and take a conic or conic-like shape.
