Abstract: Provided are a cooling structure for an LED lighting device and a light emitting module having the same. The cooling structure for an LED lighting device according to the present invention has a structure in which an LED module is disposed in a tray-shaped heat sink coupled with a lower portion of a lighting box having an LED module disposed therein to block the lower portion of the lighting box and perforated with a ventilation hole to make external air flow therein, thereby discharging heat generated from the LED module through the heat sink. Therefore, the cooling structure for an LED lighting device can have excellent cooling efficiency and can be implemented as an LED lighting device by minimizing the replacement of components of the existing metal lamp lighting device.
