Abstract
An LED assembly having an LED and a lens disposed adjacent to a light emitting surface of the LED. The area of cross-section of the lens projected onto the light emitting surface of the LED is substantially equal to or less than the area of the LED'"'"'s light emitting surface. The light emitting device can comprise an array of LEDs and an array of lenses, in which at least one lens is associated with each member of the LED array and wherein the area of a cross-section of each lens projected onto the light emitting surface of its associated LED is substantially equal to or less than the area of the LED'"'"'s light emitting surface.
