摘要： A lighting device is disclosed, and includes at least one lighting element for emitting light, an inner diffuser, and an outer diffuser. The inner diffuser defines a lighting cavity and an outer surface, where the at least one lighting element is located within the lighting cavity. The outer diffuser surrounds the inner diffuser. The outer diffuser defines an inner surface. The outer surface of the inner diffuser and the inner surface of the outer diffuser cooperate together to define a space between the inner diffuser and the outer diffuser. The inner diffuser and the outer diffuser spread and blend the light emitted by the at least one lighting element.

摘要： A driver circuit for delivering a generally constant voltage to a load is disclosed. The driver circuit includes a source of incoming AC power, a rectifier, and a constant voltage driver. The rectifier is connected to the source of incoming AC power and produces a DC voltage. The constant voltage driver receives the DC voltage from the rectifier. The constant voltage driver includes a selectively activated switching element for receiving the DC voltage, a controller, and an output line. The controller receives the DC voltage and is configured to send a drive signal to the switching element in order to activate the switching element. The output line provides the generally constant voltage to the load.

摘要： A higher power package is provided in a smaller package by providing at least first and second magnetics in parallel in first and second transformers. To limit degrading performance associated with circulating current between the two transformers, the transformers are electrically decoupled. In a preferred embodiment, the circuit includes parallel primary and secondary windings of the transformer that are decoupled electrically on an output side. Particularly, diodes are provided in a preheat portion of the circuit so that once the preheat phase is terminated, the diodes prevent current flow in one direction through the preheat portion of the circuit.
