    Abstract: A dual voltage and current control feedback control loop for an optical sensor system. A power supply provides a regulated DC voltage. A current source receives the regulated DC voltage and provides switched current to a light source. A current feedback representative of the current to the light source is provided to the power supply on a feedback path when the current source is driving the light source. A voltage feedback representative of the DC voltage is provided to the power supply on the feedback path when the current source is not driving the light source.

    Abstract: A lamp including a two-sided source plate, a plurality of light sources, a lens, a diffuser plate, and a driver insulator is disclosed. One set of the light sources generates white light and is attached to one side of the source plate. Another set of the light sources generates colored light and is attached to the source plate's other side. The lens encapsulates the white light-generating set, and redirects that white light. The driver insulator and the diffuser plate are each in contact with the source plate's other side. The driver insulator, diffuser plate, and that side of the source plate define a light box region that contains the colored light-generating set of light sources. The driver insulator acts as a reflector, and the diffuser plate acts as a diffuser, such that colored light is dispersed from the light box region through the diffuser plate.

    Abstract: A lamp having a candle-like appearance and using one or more light-emitting diodes (LEDs) as its light source. Light is emitted from only a small volume at or near the bulb's center. Heat sink and control electronics are outside the bulb. Inside the bulb, a set of secondary optics guides light to an emission point at a prescribed location in the bulb's interior. The secondary optics include a light pipe that guides light away from an LED chip, and a volume scattering element, made from a transparent base material and including transparent particles of a predetermined size and refractive index, that receives light from the light pipe, scattering it. The density of particles in the volume scattering element, the particle size, and the particle refractive index are chosen to produce a scattering pattern that directs more light toward the bulb's base, while maintaining reasonable efficiency.

    Abstract: A high frequency ballast for a metal halide lamp comprises a controller, a switch, and an oscillator. The controller selectively enables and disables the oscillator via the switch to ignite the lamp. The switch is in a power supply loop of the oscillator and selectively open circuits and close circuits the power supply loop. When the switch close circuits the power supply loop, the oscillator oscillates and provides power to the lamp. When the switch open circuits the power supply loop, the oscillator does not oscillate and does not provide power to the lamp.

    Abstract: A DC-DC flyback converter includes a transformer and a switching component connected between the transformer and a ground. The switching component controls current flow through the primary winding of the transformer. A snubber circuit is connected between ground and the connection between the transformer and the switching component. The snubber circuit reduces transient voltage spikes across the switching component. A capacitive component of the snubber circuit provides stability for a primary side auxiliary output voltage while maintaining power factor and THD performance.
