Electroluminescence light emission apparatus

摘要

An electroluminescence light emission apparatus based on a switch circuit formed of a switch element and a thyristor connected in series across a DC power source, and a control circuit for setting the thyristor and switch element in alternating conducting and non-conducting states, with an electroluminescence element being coupled between one terminal of the power source and the junction of the switch element and thyristor to be thereby alternately charged and discharged to produce emission of light.
