A light source unit (2) comprises a housing (6) which accommodates at least a light source (7), a light transmission member (9) disposed in an opening of the housing (6) such that it receives at least a part of the light from the light source (7), which light transmission member (9) is transparent for at least a part of the light which it receives, and a unit cooling system (8) which is connectable to an external cooling circuit (3) in which a cooling medium can be circulated. The unit cooling system (8) includes a cooling member (15) which is connected to the light transmission member (9) for cooling it when the light source unit (2) is in operation and a cooling medium is circulated through the unit cooling system (8). The light source unit (2) is applicable in a space (1) such as in a greenhouse so as to provide growth light to products, while heat production by the light source units (2) is minimized. |
