    摘要： A detection circuit is configured to detect the presence of an operating dimmer arranged to dim a lamp. The detection circuit includes a first circuit for measuring at a first frequency an impedance at a coupling arranged to carry a possibly dimmed feeding signal for the lamp. The first frequency is higher than the mains frequency of the mains which supplies the possibly dimmed feeding signal for the lamp. The first circuit provides a first output signal indicating the measured impedance at the first frequency. The detection circuit also includes a second circuit for analyzing the first output signal and providing a second output signal indicating whether the operating dimmer is present. The second output signal indicates that the operating dimmer is present if the measured impedance changes by at least a defined minimum deviation within a defined time interval.

    摘要： A method for evaluating signal attenuation of an impedance member includes setting at least one ideal attenuation of an ideal impedance member, setting at least one attenuation range for the at least one ideal attenuation, measuring at least one first test attenuation at a first test signal frequency of the subject impedance member, measuring at least one second test attenuation at a second test signal frequency of the subject impedance member, comparing the at least one first test attenuation and the at least one second test attenuation with the at least one attenuation range for the at least one ideal attenuation, determining whether the at least one first test attenuation and the at least one second test attenuation fall within the at least one attenuation range and performing a troubleshooting function on the subject impedance member if the at least one first test attenuation or the at least one second test attenuation fall outside the at least one attenuation range.

    摘要： A lighting device which changes a hue of light which the lighting device outputs, by changing a brightness proportion between a first light source and a second light source, the lighting device including: a light source which includes the first light source and the second light source, storage which stores control values for causing the light source to output light having a same hue as a hue of light which is output from a light source included in another lighting device; a current adjuster which calculates a first current value, and a second current value, using the control values; and a power source which supplies a first current to the first light source according to the first current value and supplies a second current to the second light source according to the second current value.

    摘要： An electrical connector assembly that includes a female and male connector assembly. The female assembly includes a primary female housing including two female terminals. A secondary female housing including two female terminals short circuited to one another. The secondary female housing affixed to a side of the primary female housing. A male connector assembly including a primary male housing including two male terminals. The two male terminals in contact with the two female terminals of the primary female housing when the primary male housing is seated in the primary female housing for providing electrical energy to the electrical component. A secondary male housing including two male terminals. The secondary male housing affixed to a side of the primary male housing, wherein at least one of the two male terminals have a shorter length than the at least two male terminals of the primary male housing.
