The invention relates to a power cable comprising at least one conductor element (10) and which additionally comprises at least one strip (16) arranged on at least one portion of the length of said conductor element (10). The strip (16) is equipped with a winding-free energy recovery system which supplies the strip (16) with electric current from the energy available in the conductor (10). The strip (16) has a plurality of elements (18) which generate light from this electric current.

A serially-connectable device includes a plug, an electrical cable, and a joining sleeve. The plug includes an insert portion and apertures are arranged in parallel to each other and formed through the insert portion. The electrical cable includes metal wires, such as wires of a light string. Ends of the wires respectively run through the apertures, and are folded back onto a surface of the insert portion to form exposed wire portions servicing as terminal pins. The joining sleeve includes two insert holes. Electrical conductors are disposed within the joining sleeve. Each electrical conductor extends from one of the two insert holes to the other insert hole. The insert portion is inserted into one of the two insert holes, to have the pins respectively contact the electrical conductors. Through the combination of the joining sleeve and the plug, two electrical cables can be quickly connected in a serial manner.

The invention relates to a power cable which comprises a central filler region (13) containing at least one conductor element (10), and additionally comprises at least one strip (16) arranged in said central filler region (13) in the vicinity of the conductor element (10). The cable is equipped with a winding-free energy recovery system (11) which supplies the strip (16) with electric current from the energy available in the conductor (10). The strip (16) has a plurality of elements which generate light from this electric current.

A LED strip having LED chips and a strip to which the LED chips are fixed and which also functions as a support structure of conductors coupled with the LED chips, and a tube manufactured from an elastic and at least partly light-transmitting material and surrounding the strip with the LED chips. At the outer surface of the tube there is a fixing element which is in essential parts of the same material as the tube. The LED strip includes a thermal conduction part which is of a material different from the tube and which, in the cross-section of the LED strip, is directed outwards from the inner surface of the tube for conducting waste heat generated in the LED chips out from the tube.

An emergency lighting assembly includes a drum that has a chute extending into the drum. A spool is rotatably disposed within the drum. The spool is biased to rotate in a first direction and the spool is urgeable to rotate in a second direction. A locking mechanism is movably integrated into the drum to inhibit the spool from rotating and to facilitate the spool to rotate. A light rope is attached to the spool and the light rope can be pulled outwardly through the chute thereby facilitating the light rope to be positioned on the roadway. The light rope is illuminated when the light rope is turned on to visually alert motorists on the roadway to the hazard on the roadway. A clasp is attached to the light rope and the clasp is attachable to a support object for retaining the light rope in a desired position on the roadway.

A method of repelling mosquitos from a locality or proximity where humans or animals will be present and/or inhibiting the mosquito from seeking a blood meal, may include positioning lighting at a location and in an orientation that will at least one of generate a photo-taxis repellent response and inhibit blood seeking by the mosquito, such that the mosquito at least one of (i) may be discouraged from entering a defined zone which the lighting protects, and (ii) may have a reduced tendency to seek a blood meal within the zone. The lighting may be LED lighting and may generate an intense light of at least 100 lux, with a colour temperature of greater than 5000K and may have a cool white spectra with two peaks, a first peak at about 450 nm-470 nm and a second peak at about 500 nm-700 nm.
