    摘要: A gate drive circuit for a controllably conductive device, such as a triac, includes a trigger circuit for conducting a gate current through a control input of the controllably conductive device, and a sense circuit operable to generate a control signal representative of the magnitude of the gate current. The controllably conductive device is adapted to be coupled in series between an AC power source and an electrical load for controlling the amount of power delivered to the electrical load. The controllably conductive device is operable to change from a non-conductive state to a conductive state in response to the gate current being conducted through the control input. A controller is operable to control the controllably conductive device via the gate drive circuit and to determine, in response to the magnitude of the gate current through the control input of the controllably conductive device, whether the controllably conductive device is presently conducting current to the load.

    摘要: A projection system for image display with at least one lamp (1), with at least one sensor (5) for detecting changes in the luminous flux delivered by said at least one lamp (1) and for compensating these changes through a suitable control of the image display and/or the lamp is described. The projection system is remarkable in that a light integrator (3) is provided, into which at least a portion of the light provided by the lamp (1) is coupled in, while the sensor (5) is optically coupled to the light integrator (3) such that it detects the luminous intensity present in the light integrator (3). Since this luminous intensity is very homogeneous because of the multiple reflections and is not influenced by brightness fluctuations caused by an optical component such as, for example, a color modulator (4), a very accurate compensation of changes in the luminous flux generated by the lamp (1) is made possible by the sensor signal.

    摘要: A lighting control system provides a desired illumination level at a task location while saving power. Controlled electric light is produced having an intensity responsive to a control signal. The system comprises at least one light fixture and a photosensor that is configured to provide the control signal to the light fixture. The control signal is responsive to an illumination level at a sensor location and ratios of illumination levels at the sensor location to task location for uncontrolled (e.g., solar) light and controlled electric light. The photosensor has the ability to self-commission. In one embodiment, the photosensor includes a self-powered photocell unit that transmits a wireless sensor signal responsive to the illumination level at the photocell unit. This photocell unit can be moved for use at different locations during photosensor commissioning.

Devices according to the present invention have two or more cells and methods of selecting and connecting one or more of the cells to a powered device. In one embodiment, multiple push button selector switches on a flashlight each connect a cell in series to a flashlight bulb. Each cell may be thereby independently connected or disconnected from the flashlight bulb. In a preferred embodiment, a voltage control sensor-switch connected in parallel to the powered device and a power cutoff relay is provided to ensure that a user selected cell combination does not deliver a combined voltage greater than a limit for incurring damage to the powered device. Unique methods of operating such devices are also provided.

    摘要: The current lighting device incorporates a seal which prevents water under external pressure from entering the device while permitting hydrogen gas under low pressure to exit. A power control activator permits the hydrogen gas to bypass the seal, thus reducing the explosive hazard. An o-ring or u-seal are used as the seals, which act as one-way valves. The lighting device has a case with a battery, electrical element and power control therewithin.

    摘要: An apparatus for driving an electric load includes a switch device interposed in a current feed path from a direct-current power source to the electric load. A sensing resistor connected in series with the switch device operates for detecting a load current as a voltage value. The load current flows into the electric load via the switch device. A signal generation device operates for generating a trapezoidal wave signal in response to externally applied commands to turn on and turn off the electric load. The trapezoidal wave signal gradually varies from a first predetermined voltage to a second predetermined voltage when the electric load starts to be turned on. The trapezoidal wave signal gradually varies from the second predetermined voltage to the first predetermined voltage when the electric load starts to be turned off. A control device operates for comparing the trapezoidal wave signal generated by the signal generation device and the voltage value provided by the sensing resistor, and for controlling the switch device in response to a result of the comparing so that the load current will vary in accordance with the trapezoidal wave signal.

    摘要: In order to control the luminosity in a room (1) lighted with several light sources (2a . . . , 3a . . . ) or several groups of light sources, a system is used with which the ratio between the light intensities of the individual light sources or groups of light sources can be adjusted or modified, and with which the total luminosity in the room (1) can be adjusted or modified while the ratio between the light intensities of the individual light sources or groups of light sources is kept constant. In particular for this purpose, a control device (7) is integrated in the system and connected to all operating devices (4a . . . , 5a . . . ) of the various light sources (2a . . . , 3a . . . ) to control the power consumption of the individual light sources (2a . . . , 3a . . . ).
