An improved LED lamp construction is disclosed having a plurality of LEDs electrically interconnected and mounted upon opposed rounded surfaces formed at one end of the lamp body. The opposed rounded surfaces comprise a substantially semi-spherical lamp head concavely open at the upper end of the lamp and a cover similar in curvature to the head and fixed across the open end thereof in a convex position relative thereto. The LEDs are arranged in multiple series groups connected in parallel and disposed circumferentially along the rounded surfaces so as to project radially therefrom in substantially all directions. The LEDs are electrically and mechanically connected to a conventional screw-type base at the opposite end of the lamp body through an intermediate stem. Depending upon the nature and level of the power source being provided to the screw-type base, the stem may-house a conventional regulator circuit intended to convert an applied level of A.C. voltage to a relatively low D.C. voltage designed to operate the LEDs. The present LED lamp is particularly suited for engagement and use within conventional traffic signal encasements of the type having a paraboloid mirror and light-diffusing lens cover wherein the LED emissions from the lamp optically combine to produce a uniform light beam.

A light-emitting diode lamp comprising: a lamp body extending along a central axis and constructed having opposed rounded surfaces sealed together at one end thereof; a plurality of light-emitting diodes electrically interconnected and mounted upon the opposed rounded surfaces of said lamp body to project light emissions in respective radial directions relative to the rounded surfaces; and electrical means connected to said lamp body at the other end thereof and coupled to said light-emitting diodes for conducting electrical power thereto.
