摘要： A lamp is provided that can have at least one interface on the lamp body for a selectable lumens and selectable correlated color temperature (CCT). In one embodiment, the lamp design includes a housing having a downlight geometry and a light engine including at least one string of light emitting diodes (LEDs), in which the light engine is position to emit light through a light emission end of the housing having the downlight geometry. The lamp also includes at least one first switch for selecting at least one lumen setting for the light emitted by the light engine; and at least one second switch for selecting at least one correlated color temperature. The first and second switch are mounted to the housing.

摘要： A tube lamp including a light source including at least one string of light emitting diodes within a tube body; end caps having pin contacts on each end of the tube body; and driver electronics including a filament detector portion provided by a passive resistance capacitor (RC) circuit that simulates the filament load of a fluorescent lamp when installed into a ballast containing fixture. The tube lamp may also include a switch for selecting light characteristics for light emitted by the light source.

摘要： A lamp including a light source having at least one string of light emitting diodes on a printed circuit board present within a tube body; and end caps having a G13 pin layout on each end of the tube body. The lamp may further include an electrical isolation switch mounted on at least one of the end caps, wherein the electrical isolation switch provides shock protection from the lamp when installed into a ballast free fixture. The lamp may further include driver electronics having a filament detector portion provided by a passive resistance capacitor (RC) circuit that simulates the filament load of a fluorescent lamp when installed into a ballast containing fixture.
