Abstract

The present invention relates to an LED light source structure, and more particularly, to an LED light source structure with high illuminating power and improved heat dissipating characteristics, in which metal having superior electric conductivity and thermal conductivity is processed into positive electrode units, and heat generated from an LED chip is directly dissipated through the electrode unit which is used as a positive electrode from among the positive electrode units, thereby improving heat dissipating characteristics, stabilizing a light source and preventing voltage drop, thus enabling output of high illuminating power. The LED light source structure with high illuminating power and improved heat dissipating characteristics is configured in that the LED chip is arranged and heat generated when the LED chip is turned on is dissipated to the outside, wherein the LED light source structure comprises: a first electrode unit (10) made of an electrically conductive material; a second electrode unit (20) made of an electrically conductive and thermally conductive material and electrically insulated from the first electrode unit (10); and an LED chip (40) arranged to use the first electrode unit (10) and the second electrode unit (20) as a positive electrode, wherein the first electrode unit (10) and the second electrode unit (20) are arranged to be brought into surface-contact with the LED chip (40), thus enabling heat generated from the LED chip (40) to be directly conducted and dissipated into the atmosphere.
