Abstract
A structure is provided to create an efficient light pattern conversion from a narrow angular light beam pattern of a light emitting source to a wide angle light intensity distribution for an omnidirectional lighting assembly. A heat conductive substrate includes an LED array with at least one central and at least one surrounding LED. A hollow light diverting component is positioned over the LED array; a central LED is within the hollow component while surrounding LEDs are positioned outside. Light emitted by the central LED is reflected off inner surfaces of the hollow component to be discharged from an upper opening. The outer component surface is configured to reflect light from the surrounding LEDs in azimuthal and circumferential directions towards a region below the upper opening. In this manner, plural LEDs are used to form a wide angle emission pattern suitable for use in conventional light bulb replacement devices.
