Abstract:
1. A method of providing a predetermined illuminated surface pattern from a predetermined energy distribution pattern of an LED light source within an LED package having a light transmitting dome comprising: providing an optic having a potentially refracting outer and inner surface for enveloping at least in part the light transmitting dome of the LED package; providing a well in a carrier; positioning the LED package within the well and the optic into the well to envelope at least in part the light transmitting dome of the LED package; and providing a shaped inner surface of the optic within the well to refract a portion of light outside of the well without impingement of the light from the LED light source onto the well, which portion of light is emitted from the LED light source into at least a portion of a forward hemispherical solid angle centered on the LED light source, which portion of light would otherwise impinge on some portion of the well but for its redirection by the inner surface of the optic.
