摘要： An assimilation lamp device (101; 800) for stimulating plant and crop growth comprises: a central lamp unit (10), comprising a body (14) and one or more LEDs (12) mounted to the bottom surface of the body, wherein the body acts as a heat sink for the heat generated by the LEDs. The device further comprises air stream generating means (42) for generating a downward air stream (43; 341), and heat transfer and exchange means for transferring heat from the body to the air stream, so that heat from the LEDs is used to increase the temperature of said downward air stream and is eventually used to warm the environment of the plants. A device controller (850) has a set point input (859) and generates control signals for the LEDs and the air stream generating means in conformity with an input signal received at its set point input.

摘要： An assimilation lamp device (1) for stimulating plant and crop growth comprises a central lamp unit (10), comprising a body (14) and a plurality of LEDs (12) mounted to an under surface of the body (14), wherein the body (14) is made of a thermally well conducting material, for instance aluminum, and acts as a heat sink for the heat generated by the LEDs. The body (14) is provided with cooling fins or lamellae (41). The assimilation lamp device further comprises air stream generating means (42) such as a fan for generating a downward air stream (43) in heat exchanging contact with the cooling fins or lamellae, so that heat is removed from the respective cooling block and used to increase the temperature of said downward air stream (43).
