In the past century different technologies have been used to generate light. Nowadays insect traps, fluorescent lamps are used to generate the so much wanted UV-A light. Pending on the type, producer and specifications, these lamps can be operated with an efficiency of up to 33%.
The commonly found 15 watt UV-A lamp is able to convert up to 33% of the incoming energy into light. This light needs to be divided in the undesired and non-effective visible light (blue light) and the much desired and invisible UV-A light.
Insect control units, located in professional & industrial environments, need to be switched on 24 hours per day & night. This way not only day insects can be attracted, but also night insects are effectively controlled. Recent studies, also conducted by Alcochem Hygiene,
By operating the lamps this way a significant energy saving can be achieved, as shown in the table, were a 4 x 15 watt unit has been examined:
Based on this conclusion Alcochem Hygiene decided to develop a new range of insect control units,
which offer the amount of light in a more flexible way: The Eco-trap range.[/column]
• During day time these units provide for 100% of UV-A light
• During night time the UV-A light is automatically reduced to only 10% of its nominal capacity, which still offers still the same reliable control on night insects, without the loss of efficiency.
