Lighting system

摘要

A lighting system comprises a plurality of discrete light emitting diode modules and a translucent portion containing the plurality of discrete light emitting diode modules. Each light emitting diode module comprises a light emitting diode and at least a first module electrode and a second module electrode. The first module electrode is in electrical connection with the cathode of the light emitting diode and the second module electrode is in electrical connection with the anode of the light emitting diode. At least a portion of the plurality of light emitting diode modules form a string of modules, with at least one module electrode of each of the light emitting diode modules in the string being in direct physical contact with a module electrode of a neighboring light emitting diode module in the string such that, when a voltage is applied across the string, current flows in each light emitting diode module in the string thereby activating the light emitting diode of each light emitting diode module in the string.
