  • Patent number: 10051700
    Abstract: A multi-group brightness controllable LED tube comprises a multi-input source selector which directs electric power to the tube from a set of diversion switches inserted between a power source and preexisting ballast. The diversion switches automatically re-establish new electric current paths to supply the LED tube power and safely bypass the preexisting ballast. The LED tube also comprises a digital sub section selector for selecting two groups of SMD (surface mounted device) LED strip lights for intensity control. When first turned on, the light will be at 66% brightness. A first toggle action dims the light to 33% brightness, and a second toggle action brings it up to 100%. The third toggle will reset the LED tube to 66% brightness. The retrofitted LED tube is suitable for single end as well as double end fixtures without a complicated conversion process. Furthermore, fixtures can be reverted back to original fluorescent operation.

The lighting unit 50 is composed of a rectifier/smoothing circuit module having an electrolytic capacitor 53, an inverter circuit module, and a resonant circuit module having a resonance capacitor 54. The circuit modules are mounted on a printed wiring board 51. An inrush current limiting resistor 62 is connected to the input end of the rectifier/smoothing circuit module and in contact with the electrolytic capacitor 53 and the resonance capacitor 54 at their outer circumferential surfaces.

  • Patent number: 7427839
    Abstract: An inductive power supply system for providing power to one or more inductively powered devices. The system includes a mechanism for varying the physical distance or the respective orientation between the primary coil and secondary coil to control the amount of power supplied to the inductively powered device. In another aspect, the present invention is directed to an inductive power supply system having a primary coil and a receptacle disposed within the magnetic field generated by the primary coil. One or more inductively powered devices are placed randomly within the receptacle to receive power inductively from the primary coil. The power supply circuit includes circuitry for adjusting the power supplied to the primary coil to optimize operation based on the position and cumulative characteristics of the inductively powered device(s) disposed within the receptacle.

  • Patent number: 7365951
    Abstract: A method and apparatus for protecting a discharge lamp lighting device from damage due to mis-wiring of a source of electrical power to the discharge lamp lighting device. The protection apparatus includes a detector, a comparer and an inhibitor. The detector samples at least one monitor point associated with the discharge lamp lighting device to obtain at least one detection voltage. The comparer compares the at least one detection voltage with a reference voltage. The inhibitor inhibits an operation of the discharge lamp lighting device when the comparer determines that a mis-wiring of the source of electrical power to the discharge lamp lighting device exists.
