Tubular housing with light emitting diodes

Abstract

An LED lamp comprising a tubular wall circular, oval, or multi-faceted in cross-section having tubular wall ends. At least one electrical string mounted within the tubular wall extends between the tubular wall ends with at least one LED electrically mounted thereto. Electrical circuit means providing power to at least one LED from the ballast assembly of a fluorescent lamp fixture. Electrical circuit means include an LED circuit including at least one electrical string each having one LED or a plurality of LEDs connected in series thereto. The at least one electrical string can further include two electrical strings in parallel or a plurality of parallel electrical strings. Means for suppressing voltage delivered from the ballast assembly to an LED operating voltage within the design capacity of said plurality of LEDs in electrical connection with the electrical circuit means. The LED lamp can have opposed single-pin or bi-pin electrical contacts for use with ballast opposed single or double contact electrical sockets connected to electronic instant start, electronic rapid start, hybrid, or magnetic ballast assemblies. The means for supporting the LEDs and the LED electrical circuit including the parallel electrical strings can be either a single generally cylindrical self-biased LED circuit board mounted and held in the tubular wall, or a plurality of rigid flat support structures spaced apart and held in the tubular wall. Side-emitting radial beam high-brightness LEDs can be mounted to the support structures.
