<p>A light bulb (10) comprises a base (12) including at least first (14), second (16), and third (28) electrical contacts. An optically-transmissive envelope (20) is hermetically sealed to the base (12) and contains a noble gas. At least one filament is disposed within the optically-transmissive envelope (12) and is electrically coupled between the first (14) and second (16) electrical contacts. At least one non-incandescent electric light source is also disposed within the optically-transmissive envelope (12) and is functionally independent from the filament (18) and electrically coupled between the first (14) and third (28) electrical contacts.</p> |
