Apparatus for connecting a wiring harness to a sectional door is disclosed. The sectional door has a plurality of panels in which adjacent panels are connected by a hinge, the hinge is connected to the adjacent panels by first and second hinge connectors. The apparatus includes a first bracket which has a proximal end and an opposite distal end, the distal end is shaped and dimensioned to receive the wiring harness. The proximal end of the first bracket is connectable to the hinge by the first hinge connector. A second bracket has a proximal end and an opposite distal end, the distal end is shaped and dimensioned to receive the wiring harness. The proximal end of the second bracket is connectable to the hinge by the second hinge connector. The wiring harness is connected to the distal ends of the first and second brackets, thereby providing strain relief for the wiring harness.

A portable light bulb system includes a bulb that is removably coupled to a mounting bracket affixed to a support surface. The bulb includes an internal battery power supply and a LED light engine. A base of the bulb has a diameter sized to prevent the base from being inadvertently inserted into a conventional 110 volt electrical light bulb socket. The system also includes a wireless module communication device configured to wirelessly communicate with the bulb. In a first use position, operation of the bulb provides illumination to a region proximate the mounting bracket affixed to the support surface. An operator can disconnect the bulb from the bracket and bring the bulb to a second use position where operation of the bulb provides illumination to the second region. The operator can then return the bulb to the bracket at the first use position, or bring the bulb to yet another location for illumination.

An LED-based light includes one or more LEDs, a sensor arranged to detect a brightness level in an area resulting from the combination of light emitted by the LEDs with light from at least one ambient light source other than the LEDs, and operable to output a signal corresponding to the detected brightness level, a controller operable to regulate an amount of power provided to the LEDs in response to the signal, a light transmitting housing for the LEDs, the sensor and the controller and a connector shaped for connection with a light socket disposed at an end of the housing.

Semiconductor lamp having a straight, translucent tube whose open end faces can be closed by means of respective end caps, which end caps are plug-connected to the tube, a circuit board which is equipped with at least one semiconductor light source is installed in the tube and is in contact with at least one of the end caps, wherein both end caps are mechanically connected to one another by means of a connection element running in the tube, at least one of the end caps is arranged such that it can be displaced longitudinally with play with respect to the tube and thermal expansion of the connection element in a longitudinal direction of the tube is smaller than thermal expansion of the tube and wherein the connection element is snap-fitted to at least one of the end caps. The invention can for example be used for retrofit or replacement lamps for conventional elongate lamps (e.g., fluorescent lamps and tube lamps).
