The basic principles of LightLab’s technology 

LightLab’s technology is based on two physical phenomena: field emission and cathode luminescence. Put simply, this means that light is created by generating an electron flow in a cold cathode. The electrons are emitted by the cathode and strike the inside of a lamp glass coated with light powder (luminescent layer) and a very thin layer of aluminium, creating light. The properties of the light, e.g. wavelength, are controlled entirely by the light powder. Red, yellow, green, blue and ultraviolet light can be generated in this way.

Unique, nanostructured cathode

The secret behind this is a unique cathode with a patented structure of zinc oxide. Small, sharp nano-tips emit an electron flow when power is supplied.

The figure below shows the principle structure of a UV light source. On the far right is the cathode with the nanostructures, which send out (emit) electrons. The electrons pass through the conductive layer and reach the light-emitting material. The light that is generated then comes out through the glass.

Footnote:A nanostructure is a structure of a size between microscopic and molecular structures. One nanometre is one billionth (0.000000001) of a metre. If you compare one nanometre with one metre, you have the same ratio as between the diameters of a normal football and the Earth.
