## Abstract

A strip LED comprises an LED chip, an embedded resistor, a magnet, a magnetic material, a strip encapsulation bracket and a power source. An installation bracket for the embedded resistor and the LED chip is provided between connection brackets. The connection bracket metal strips a and b and metal strips c and d are either a single narrow and thin metal strip or a plurality of thin metal wire structures. The magnet is fixed at one end of a wire, and another end of the wire is connected to the power source.
