a housing;
an irradiation device arranged within the housing and having a discharge lamp with an integrated reflector made of quartz glass, wherein the reflector is arranged on an outer surface of the discharge lamp; and
a cooling system configured to promote convective air flow through at least a portion of the housing.
2. The module according to claim 1 , wherein the reflector comprises a coating made of opaque quartz glass.
3. The module according to claim 2 , wherein the coating comprises synthetic quartz glass.
4. The module according to claim 1 , wherein the reflector is a wide-band reflector.
5. The module according to claim 1 , wherein the discharge lamp is a UV lamp.
6. The module according to claim 1 , wherein the discharge lamp is a mercury medium-pressure emitter.
7. The module according to claim 1 , wherein the discharge lamp is a low-pressure emitter.
8. The module according to claim 1 , wherein the discharge lamp is a high-pressure emitter.
9. A method for production of a module according to claim 1 , wherein the reflector is applied as a coating on the discharge lamp of the irradiation module.
10. The module according to claim 1 , wherein the cooling system comprises a plate disposed at a top side of the housing, the plate including a plurality of outflow openings.
11. The module according to claim 1 , wherein the cooling system comprises a ventilator and one or more openings in the housing.
12. The module according to claim 11 , wherein the ventilator is configured to supply cold air that is discharged through the one or more openings in the housing.
