摘要： In a lamp lighting ballast which generates a lamp lighting signal for a lamp, provided is a striation elimination circuit to increase the lumen output frequency for elimination of visual striations which may occur within the lamp. An even harmonic signal generator is configured to generate an even harmonic waveform, and an injection point is configured to receive the even harmonic signal into the lamp lighting system. The injection point is located at a location wherein the even harmonic signal alters the lamp lighting signal from a symmetric signal configuration to a high content even harmonic signal configuration prior to being received by the lamp.

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.
