Disclosed is a rectifierless light string that uses bidirectional LEDs. Each LED is illuminated on both the positive and the negative portion of an AC signal so that the AC signal does not have to be rectified. In addition, LEDs are mounted on LED holder plugs, which are designed to allow the LEDs and bypass resistors to be automatically inserted in the LED holder plug. The LED holder plugs are inserted into a light string socket that contains a shunt switch that provides a conduction path when the LED holder plug is not firmly inserted in the light string socket. In this manner, conduction can occur in the light string when the LED holder plug is dislodged.

A cable light includes a battery receptacle that is electrically coupled to a first light module and a second light module. The battery receptacle includes a battery port that receives and retains a battery, such as a power tool battery pack. The first light module and the second light module each include a housing supporting a lens, a light emitter such as an LED, a reflector, and a hanger to hang the light modules on a workpiece. The first light module is electrically coupled to the battery receptacle, and the second light module is electrically coupled to the battery receptacle via a connection with the first light module. The battery receptacle communicates electrical power from the battery pack to the light modules to power the light emitters.

Disclosed is a luminous necklace structure. The present invention adopts the following technical solution: a luminous necklace structure, comprising a battery case; a chain rope with both ends connected with the battery case; pendant(s), at least one of which is connected with the chain rope, so that the battery case can supply power to the chain rope and make the pendant(s) luminous. The beneficial effects of the present invention are as follows: the chain rope and the light shade adopt diversified connecting methods which are more flexible and convenient for use, the movable connection between the light holder and the light shade makes the luminophor changeable, thus prolonging the service life of the luminous necklace and meanwhile saving the costs, and the same luminous necklace is allowed to be provided with either luminous or non-luminous light shade, thus enhancing the luminous effect of the necklace.

A sleeve for decorative lighting helps prevent tangled lighting wires. The sleeve has clamps at each end that clamp the lighting wires. The sleeve is flexible and may be elastic. The sleeve may be a light diffuser so that the decorative lighting can be used while in the sleeve. A decorative lighting string has retractable lights and may be at least stored in the sleeve.
