PURPOSE: An LED lighting apparatus is provided to effectively cool the heat generated by an LED element by forming an LED module which unitizes a circuit board and a thermoelectric cooling module. CONSTITUTION: An LED module(100) mounts one or more LED elements. A power module(400) supplies power. A cover part(600) protects the LED element and a circuit board. Both sides of a top insulated substrate comprise an electrode pattern. One or more LED elements are mounted on the electrode pattern of the top insulated substrate. The upper side of a bottom insulated substrate comprises the electrode pattern. A plurality of thermoelectric elements is formed between the electrode patterns of the top insulated substrate and the bottom insulated substrate. An anti-diffusion layer is formed between the electrode pattern and the thermoelectric element. |
