Beschreibung
Zusammenfassung:	The invention relates to an LED lighting device (100). The LED lighting device comprises a cover body (1), an optical engine (2), an optical component (3) and a driver (4), wherein the optical engine (2), the optical component (3) and the driver (4) are contained in the cover body (1). The interior of the cover body (1) is divided into a first cavity (11) for containing the optical component (3) and a second cavity (12) for containing the driver (4) by the optical engine (2). The lighting device is characterized in that the optical engine (2) is designed to enable the airflow of the first cavity (11) and the airflow of the second cavity (12) to be communicated; and the cover body (1) and the optical component (3) are designed to enable the airflow of the first cavity (11) and the second cavity (12) to be communicated with the airflow of the ambient environment.
