    Abstract: An inductively coupled LED lighting system including an LED light module mountable on one side of a surface of a partition and a power module mountable on an opposing surface. The LED light module and the power module are aligned to allow for an inductive transfer of power. The LED light module includes a first coil connected to one or more LEDs. The LED light module also includes a base, a lens fixed to the base enclosing the circuitry in an enclosure and attachment means for attaching the LED light module to a surface. An alternating current or a direct current power source is connected to the power module. Alternating current or pulsed direct current is directed through a connected first coil creating a fluctuating inductive field. Electromagnetic power produced in the power module coil is inductively transferred to the coil in the LED light module powering the LEDs.

  • Patent number: 8143793
    Abstract: An energy efficient illumination device is provided in which energy consumption is reduced by using a pulse generating circuit which provides power to LEDs in short pulses, and in which the circuit has a lifespan which is comparable to that of an LED. The illumination device includes a pulse generator circuit employing only passive circuit components and which is used to generate a desired pulsed and positively DC biased output waveform. The pulse generator circuit receives alternating current power as an input, alters the power waveform, and supplies the power to LEDs for a very short time (0.2-15 ms) during each cycle of a 50-60 Hz input signal. This paradigm of pulsed light emission provides ambient lighting that is perceived by humans to be steady and continuous, and which also provides substantial energy savings since power is used in only a fraction of the power cycle.

  • Patent number: 7683552
    Abstract: A circuit structure for a lamp set which includes a socket, a lamp assembly mounted onto the socket and an electrode portion. The lamp assembly surrounds a housing space inside to hold a power distribution dock connecting to the socket. The power distribution dock has a holding space to hold a power conversion element which is electrically connected to the electrode portion to receive external electric power and transform to starting power to drive the lamp assembly to generate light. The power distribution dock and the power conversion element are located in the housing space. Thus the total height of the socket is reduced and the lamp set can be shrunk to a smaller size.

  • Patent number: 7626338
    Abstract: A discharge lamp lighting apparatus includes a transformer unit, a casing for housing the transformer unit, and a circuit board including circuit components. In the casing, the circuit board is joined to the casing and the transformer unit is fixed to the circuit board through a heat conductive member having thermal conductivity of more than 0.1 W/(m·k). Heat produced by the transformer unit is transferred to the casing through the heat conductive member and released through the casing effectively. In the lighting apparatus, therefore, while the transformer unit is arranged relatively close to the circuit components, the heat can be prevented from affecting the circuit components.

  • Publication number: 20090058302
    Abstract: A ballast circuit that facilitates providing thermal protection for a fluorescent lamp includes a coupling transformer that couples an inverter circuit to a control circuit. First and second transformer windings in the inverter circuit, and a third transformer winding in the control circuit, are wound around a common ferrite core. The ferrite core has a Curie temperature that approximates a maximum allowable threshold temperature for the lamp. When the temperature of the ballast approaches the Curie temperature of the ferrite core, its permeability, and thus inductance, drops dramatically, causing an increase in operating frequency in the inverter circuit. This increased operating frequency causes a capacitor in the control circuit to charge to a threshold voltage, at which power to the inverter circuit is reduced. The lamp then dims without turning off until the temperature is reduced to an acceptable level.

  • Patent number: 7250726
    Abstract: An apparatus and methods for balancing current in multiple negative impedance gas discharge lamp loads. Embodiments advantageously include balancing transformer configurations that are relatively cost-effective, reliable, efficient, and good performing. Embodiments include configurations that are applicable to any number of gas discharge tubes, such as cold cathode fluorescent lamps. The balancing transformer configuration techniques permit a relatively small number of power inverters, such as one power inverter, to power multiple lamps in parallel. One embodiment of a balancing transformer includes a safety winding which can be used to protect the balancing transformer in the event of a lamp failure and can be used to provide an indication of a failed lamp.

  • Patent number: 7095177
    Abstract: EL light emitting device includes a cylindrical EL light emitting unit and a columnar power feeding unit. EL light emitting unit is composed such that a cylindrical receiver coil is arranged and connected along an inner circumferential face of the cylindrical EL light emitting element and integrated into a single body by an outer cover member. The power feeding unit is formed in a columnar shape whose diameter is smaller than an inner diameter of EL light emitting unit so that the power feeding unit can be inserted into the cylindrical EL light emitting unit. When the power feeding unit is inserted into EL light emitting unit and the power feeding unit is impressed with an alternating voltage, a high alternating voltage corresponding to the turn rate of both coils is generated in the receiver coil, so that light can be emitted from EL light emitting element.
