Claim:
A light emitting diode (LED) lamp apparatus, comprising: an LED; a light diffusing cap formed from a light transmitting material and positioned at a emission side of the LED, the light diffusing cap being generally cup-shaped and having a circular center portion, an first annular peripheral portion, wherein the first annular peripheral portion has a light diffusing finish such that light that passes through the first annular peripheral portion is diffused to a higher degree than light that passes through the center portion, and the light diffusing finish is uniform throughout the first annular peripheral portion, and a second annular peripheral portion, wherein the second annular peripheral portion has a light diffusing finish has a light diffusing finish such that light that passes through the second annular peripheral portion is diffused to a higher degree than light that passes through the first annular peripheral portion, and the light diffusing finish is uniform throughout the second annular peripheral portion, wherein the brightness of light emanating from the light diffusing cap increases in a direction from any location at an outer edge of the peripheral portion of the light diffusing cap toward the center of the cap.
