<p>An electroluminescent (EL) lighting system (10, 12) is disclosed including a lamp (12) which has a low dielectric constant binder, phosphor-embedded matrix (33) sandwiched between two conductive electrodes (31, 35) and which is pulsed at a high frequency by a low voltage battery-powered driving circuit (10). The lamp exhibits characteristics such as long half-life, improved maintenance, high light emission of uniform intensity, high figure of merit, minimal internal heating, no impedance matching to drive circuit and no critical point of attachment of drive circuit to lamp since lamp has low electrical loss factor. The lamp does not permanently fail when punctured or when dielectric strength is exceeded. At least one of the conductive electrodes (31, 35) is light transmitting. The matrix (33) is non-hygroscopic and the phosphor is encapsulated.</p> |
