LED lamp for outdoor application, has control unit electrically connected to LED and with cooling fan that is attached to dissipative element, enabling cooling fan to allow airflow upwards and enabling LED to light up using delay circuit
The lamp has a column-shaped, heat dissipative element (11) comprising an axially extending air passage, and a cooling fan (12) attached to the dissipative element and an upper end of the air passage. An LED (13) is attached at a surface area of the dissipative element. A control unit is electrically connected to the LED and with the cooling fan, and enables the cooling fan to allow airflow upwards and enables the LED to light up using a delay circuit. A temperature sensor detects temperature of the dissipative element.
