ABSTRACT:
A flexible lighting strip comprises an elongate section of a plastics material having a portion formed as a cylindrical duct which houses a chain of electric lamps. At the rear of that portion is a hollow portion which contains a pair of conductors for feeding the lamps, and which is filled with a translucent polymerizable compound. Between those portions is a portion which has a longitudinal triangular slit, the apex of which opens into the duct so that connections from the conductors to the lamps pass transversely through the slit and are gripped at the apex. A thin metallic sheet covers the filling of translucent compound and is adhered thereto by polymerization of the compound. A double-sided adhesive tape is preferably attached to the metallic sheet for attachment of the lighting strip to a support such as a showcase.
