The artificial light source HL 313.01 enables solar energy experiments independently of natural sunlight. As a result, trainers for the use of solar energy such as ET 250, ET 255, ET 256, HL 313, HL 314, HL 320.03 or HL 320.04 can be operated in closed laboratory rooms. With this light source, it is possible to ensure reproducible test conditions at any time.
The light source contains eight halogen lamps arranged in two rows. The angle of inclination of the individual halogen lamps can be adjusted in order to adapt the irradiation for the respective experiment. The illuminance can be altered by changing the distance to the respective light absorber.
