Nowadays, lighting represents 20% of the global electricity consumption. Light can be produced
using different technologies but more than 100 years after its invention, the incandescent bulb is
still the most sold and one of the more used light sources. Of the total energy input in an
incandescent bulb more than 90% is lost as heat while less than 10% is converted into visible
light. However, there are alternative technologies which use up to 85% less energy for
conventional lighting and there are even more efficient light sources for other purposes that if
they replace completely all incandescent lamps over the world could reduce dramatically the
global electricity consumption and greenhouse gases emissions. One may identify these
alternative technologies mainly as LEDs and discharge lamps, but are they the unique
This thesis is focused on a new lighting technology whose name is LightLab and which is
based on the field emission and cathodoluminescence concepts. This technology is under the
research and development stage but prototypes have already achieved energy savings over 85%
compared to incandescent lamps with a great color performance and with the advantage that it
does not use mercury or other hazardous substances compared with discharge lamps.
Thus, in the first part of the project all technologies and last improvements are studied while
the second part analyses the market applications possibilities for the LightLab lamp considering
the environmental perspective regulations and comparing the lamp with the other light sources.
The result is that despite there are still some unknown parameters that need to be developed or
improved, the lamp has a great potential for different applications fields.
