Abstract:
A linear light-emitting diode (LED)-based solid-state device comprising a curved surface to hold a flexible printed circuit board with multiple linear arrays of surface mount LEDs provides lighting applications with a broad viewing angle over 180° along the radial direction. On each of the two lamp bases of the lamp, a shock-protection switch is mounted to prevent shock hazard during re-lamping.
