Abstract:
An electroluminescent light source for providing a source of electroluminescent light to electronic equipment, comprising:a printed circuit board on which an electronic circuit component is mounted; an electroluminescent device, which is disposed in close contact with the printed circuit board and which generates light due to the application of a high voltage alternating current to said electroluminescent device; a click board disposed on said printed circuit board, said click board switching a switch contact point between on and off positions in response to depression of a key button; a bracing seat which fixes said click board to said printed circuit board; and a shield member which is disposed between said electroluminescent device and said click board and between said electroluminescent device and said printed circuit board, and which shields said electronic circuit component on said printed circuit board from being excited by the high voltage alternating current applied to the electroluminescent device, said shield member being constructed by a shield layer printed onto said bracing seat.
