摘要： A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).

摘要： Systems and methods for reducing problems and disadvantages associated with traditional approaches to masking false faults generated by voltage regulators are provided. A method may include receiving, at a voltage regulator configured to be enabled by a power controller communicatively coupled to the voltage regulator via an enable line, a first indication from a device other than the power controller indicating that the voltage regulator is to be disabled, wherein the enable line is configured to communicate a second indication from the power controller to the voltage regulator indicating whether the voltage regulator is to be enabled. In response to receipt of the first signal, the voltage regulator may communicate to the power controller via the enable line, a third indication indicating that the voltage regulator has been disabled by a device other than the power controller.
