ABSTRACT:
An improved LED lamp having a uniquely shaped envelope to distribute the radiated light energy into a uniformly distributed spherical pattern. This novel lamp allows a 360 degree viewing angle in a horizontal plane about its central vertical axis, as well as, a 360 viewing angle about the vertical circle. The present invention utilizes a uniquely designed concave lens to establish a focal point within the envelope to re-radiate the radiant energy in a more efficient manner thereby creating a higher intensity without increasing the input power. Conventional LED's have a directional conical shaped pattern of concentrated light energy that provides suitable use in panel indicator lamp applications.
