Multiple light emitting diodes (LEDs) are attached to the current output of the electronic ballast circuit, and current is driven from the current output to light said LEDs. Optionally, prior to driving current through the LEDs, the impedance of the current output is sensed; and the current is driven through the LEDs to light the LEDs upon detection of an impedance significantly lower than an impedance characteristic of the HID lamp. Ignition appropriate to ignite the high intensity discharge is not performed when LEDS are attached to the current output. Alternatively, a signal is provided to disconnect the LEDs during a high voltage output for ignition of the high intensity discharge (HID) lamp.

    Abstract: A lighting system and method combine at least one LED and at least one gas discharge lamp within a common housing. The lighting system includes a control system to dependently operate each LED and each gas discharge lamp during overlapping, non-identical periods of time. In at least one embodiment, the control system can provide light output by activating LEDs during gas discharge preheating operations and thus extend the useful life of each gas discharge lamp. When dimming the lighting system, the control system can reduce current to the gas discharge lamps and one or more gas discharge lamps can be phased out as dimming levels decrease. As dimming levels decrease, one or more of the LEDs can be activated or groups of LEDs can be phased in to replace the light output of the dimmed gas discharge lamps. Thus, the lighting system can reduce power consumption at low dimming levels.

  • Patent number: 6621224
    Abstract: A light-controlling device of this invention includes a controlling circuit having a function for turning an incandescent lamp and an LED off simultaneously, which have different minimum voltages each other at predetermined illumination. When illumination of the lamp and the LED decrease to the predetermined illumination by rotating an operating section of a variable resistor, the controlling circuit turns the lamp and the LED off based on a signal from a detecting switch linked with rotating operation of the operating section. As a result, an operator does not feel strange.

  • Patent number: 6169373
    Abstract: A work light includes a generally cylindrical, at least partly transparent housing, a first light source which is an elongated, rodlike bulb disposed within the housing, a second light source which is a narrow beam bulb disposed within the housing at one end face thereof, a connection of the first light source to an alternating current electrical main and a hangar hook projecting externally from the housing. Circuitry is also provided for converting alternating current of a first frequency from the main into direct current, for converting the direct current into alternating current of a second frequency substantially higher than the first frequency, and for selectively operating the first light source and the second light source with the alternating current of a second frequency.

  • Patent number: 6155694
    Abstract: A multi-flash strobe light pattern is superimposed on each individual light pulse produced by an incandescent lamp to provide a warning signal of enhanced visibility in a particulate laden ambient environment. The first pulse of each multi-flash strobe pattern is delayed for a time period, subsequent to energization of the incandescent lamp, which is equal to at least 80% of the time required for the incandescent lamp to achieve its maximum light output intensity.

  • Patent number: 5793164
    Abstract: A wing tip system for rotor craft includes a downwardly-facing light housing to provide a visual aid to rotor wingtip position. This system is visible to crew members and to adjacent crew, particularly when using night vision goggles (NVG) or other ambient night vision (ANVIS) equipment. This allows tip lighting to be provided in situations where covert helicopter operations are desired. The lighting further is compatible with ANVIS equipment, in that it permits operation noncandescent light in order to prevent blooming or other effects which would otherwise diminish the effectiveness of the ANVIS equipment. The lighting system further has a higher level of illumination, in which rotor tip lighting is increased to become more visible without the use of ANVIS equipment.

  • Patent number: 5763964
    Abstract: A high frequency power supply for distributed luminous tube signage including a master power unit and one or more slave units. The master unit includes a digital oscillator, controller, and electronic switches to induce a switched high frequency waveform across the primary of an output transformer. This waveform is preferably of a non-symmetrical variety to minimize neon bubble formation and mercury gas migration. The output transformer includes one or more low voltage ancillary power outputs for interconnection through appropriate twisted pairs or other transmission medium to the slave units. A high voltage secondary for direct luminous tube connection may also be provided. Various slave unit topologies are contemplated including remote or moving luminous tube segments; electronic controllers and sequencers, and motors.

  • Patent number: 5661367
    Abstract: A high pressure gas discharge lamp includes first and second discharge devices electrically connected in series within an outer envelope. The discharge devices each include a discharge vessel enclosing a discharge space with an ionizable fill and first and second discharge electrode assemblies. The first discharge electrode assemblies of the discharge devices are connected so as to receive a starting pulse and lamp operating voltage. Each discharge vessel includes a first wall portion spaced from the first discharge electrode assembly and defining an ionizable gap therebetween. A conductive element bridges the discharge devices at the first wall portions and capacitively couples the first discharge electrode assemblies to induce ionization in one of the discharge devices in the ionizable gap between the first wall portion and first discharge electrode assembly.

  • Patent number: 5661347
    Abstract: In accordance with the invention the circuitry arrangement comprises a central unit (5) and a plurality of peripheral units, such as control apparatuses for lamps, connected with the central unit via a data bus. These peripheral units are each connected with the data bus (1) via a coupling unit (3), each coupling unit (3) having a receiving branch for the transfer of information from the central unit (5) to the peripheral unit, and a transmission branch for the transfer of information from the peripheral unit to the central unit (5). Here, the central unit (5) sends out information in the form of a modulated a.c or pulse voltage onto the data bus. The transmission branch applies information to the data bus (1) in that the output resistance of the transmission branch is varied. Because the receiving branch in the coupling unit (3) is continuously active and the transmission branch is inactive in the case of non-sending operation, at most a very small return current is consumed in the coupling unit (3).

  • Patent number: 5491385
    Abstract: A compact folded fluorescent lamp and a small incandescent lamp are both mounted on an ordinary Edison-type screw-base capable of being screwed into an ordinary lamp socket at which ordinary AC power line voltage is controllably provided. An inverter-type ballast is integrally combined with the base and is operable to power the fluorescent lamp whenever the base is indeed screwed into the lamp socket. The incandescent lamp is powered from the AC power line voltage by way of an SCR whose conduction angle is controlled such as to cause the total light provided from the combination fluorescent-incandescent lamp to remain substantially constant from the very first moment that AC power line voltage is provided at the lamp socket. Thus, when the AC power line voltage is initially provided, the light provided from the incandescent lamp will be at its maximum while the light provided from the fluorescent lamp will be at its minimum.
