LED illumination structure

Abstract

A light emitting diode (LED) illumination structure has a button-sized battery, a circuit board, an LED chip and a contact switch. A positive electrode of the LED chip electrically connects to a positive electrode of the button-sized battery, and a negative electrode of the LED chip electrically connects to the circuit board via a conductive wire. A transparent molding material encapsulates the LED chip and the conductive wire. One terminal of the contact switch electrically connects to the circuit board while the other terminal connects to a negative electrode of the button-sized battery. Direct attachment of the positive electrode of the LED chip to the positive electrode of the button-sized battery provides electrical connection and heat dissipation from the LED chip through the button-sized battery to stabilize the high brightness characteristic. The LED illumination structure is thereby constructed with a reduced size.
