LINEAR SOLID-STATE LIGHTING WITH VOLTAGE SENSING MECHANISM FREE OF FIRE AND SHOCK HAZARDS

摘要

A linear light-emitting diode (LED)-based solid-state lamp using a novel voltage sensing and control mechanism operates normally in both single-ended and double-ended luminaire fixtures. The voltage sensing and control mechanisms automatically detect supply source configuration in the fixture and make proper management so that the linear LED lamp works in any fixtures without operational uncertainty or risk of fire. When used with shock protection switches on the two lamp bases at two opposite ends, the universal lamp fully protects a person from possible electric shock during initial installation and re-lamping.
