In order to achieve the best possible result from an electric insect trap, the light source (4) is surrounded by a lightpermeable, preferably blue, globe (15), which has a size that leaves an air gap (1) between the globe and the surrounding tube (13) in which the light source is mounted. Behind the light source the fan (11, 6) is mounted in a tube (14) where this has a smaller cross sectional area than opposite the globe. Hereby a high air velocity is ensured and thus a high degree of effectiveness in that the insects cannot fly across the air current and escape it. Since the globe (15) is easily removed it is easily and quickly cleaned because its surface temperature is low which means that insects do not burn and stick to the surface. |
