Abstract
The present invention relates to lighting strips and more particularly to flexible lighting systems and devices, which are waterproof. The lighting strips are modular and are capable of being physically and electrically connected with one another to provide lighting systems that are waterproof and adaptable to many situations. Included in embodiments of the invention are modular lighting strips comprising: a non-conductive substrate strip comprising an electrical circuit; a plurality of high brightness LEDs operably connected to the electrical circuit; a colloid layer comprising polyurethane resin providing a waterproof coating over the substrate, the circuit, and the LEDs; and a plug at one end and a socket at an opposing end of the substrate which is integrally formed with the strip to provide for waterproof electrical interconnection of two or more circuits or to a power supply. The lighting strips of the invention can be used in particular for back lighting, accent lighting, aisle or path lighting, contour lighting, elegant interior decoration, holiday decorations, or landscape lighting.
