Light-traps, the earliest using paraffin or acetylene lamps, have been used for many years to catch insects and many papers have been published dealing with various trap designs, different light sources and factors influencing catch size.

Location of the mercury-vapour lamps are limited by available grid power, or they can work with a generator. The small portable light traps can be easily located at different habitats, since they work with 12 V batteries. These portable light traps were placed about 100 m distance from each...
Light-emitting-diode lamps are widely used because of their long lifespan and excellent electric efficiency. Recently, LED light sources were introduced in several vitrectomy machines for endo-illumination of the retina1. Despite the several advantages of LEDs, many researchers have reported that ...
If one or more lamps are loosened, the alarm of the present invention causes the discernible alarm to go on, thereby startling a burglar and alerting the neighbors if a flood light lamp is unscrewed from a security light while the switch inside the house is turned on, regardless of whether...
Understanding these phenomena is increasingly important as the light from modern lamps, such as LEDs, typically contains a greater percentage of blue light, making them more biologically effective, and the use of devices that emit artificial light (e.g., smartphones) becomes more pervasive4,26,...
These are regions with high death rates from vector-borne disease [4], making it important to determine how these lights perform as vector attractants. A small difference in attractiveness between two lights can become a large difference in insect numbers when many lights are used over a wide ...
Also, incandescent filament and gas discharge lamps are currently available [17]. LLLT has been the prevailing PDT for a long time [18] even if many limitations are reported for this approach: complicated clinical setting, wavelengths used, or area that can be covered by light. LEDs ...
