Basic principles 

LightLab has created a very strong technical platform, protected by several patents, and has built up a broad knowledge in the area of ​​field emission technology, combined with cathodoluminescence for lighting.

LightLab develops technologies to achieve cost-effective nanostructures that is used in several ways. In the field emission lamps it is used in a cathode to generate an electron flow from the material. In principle, the electrical field at the tips of the nanostructures are so high that the electrons are drawn out of the material, without the need to supply energy in other ways, e.g. in the form of heat. The electrons are then accelerated in vacuum by the electric field towards an anode which is coated with a material that generates photons (light) when hit by electrons. The properties of light (wavelength, or spectrum) is completely determined by the properties of that material. Red, yellow, green, blue and ultraviolet light can be generated in this way. It is also possible to generate X-rays.

The figure below shows the basic structure of a UV light source. At the far right is the cathode with nanostructures, which emits electrons. The electrons strikes the inside of a lamp glass coated the conductive layer and reaches the light-emitting material, creating light.
