Orvieto celebrated Saint Patrick’s Day joining the Tourism Ireland’s Global Greening initiative, at its 9th edition. Together with Saint Patrick’s Well, another popular monument of the town was illuminated with the Irish shamrock thanks to Grandi Proiezioni, the company specialised in conception, planning and implementation of luminous scenography, distributor for Goboservice projectors in Tuscany.
Golux, a new series of Gobo Projector made by Goboservice, recently debuted internationally in Paris, projecting gobos on architectural works such as La Tour Eiffel, the “Invalides” dome, the Arc de Triomphe and the National Library. The four most important monuments have unintentionally been the backdrop to the self-promotional incursions of the well-known French artist, John Hamon – the “most famous unknown face of the capital” – as the media renamed it, whose enigmatic smile has recently become more renowned than that of the Gioconda, especially now that it has been projected with a powerful and concentrated beam of light on the monuments of Paris.
It is the more than gratifying the rating cetificated by “eKomi”, the feedback company which collects customers evaluations by means of a standardized SaaS software. 5 golden stars but with stronger results in the French and German market, where peolple are more used to give critical feedback concerning online purchased products and services.
Not everything is as it seems, especially when dealing with lights, shadows and reflections.
For example, take a look at the following picture which shows the projection of two black-and-white gobos.
Discharge lamps need auxiliary electronics for supplying the correct voltages of ignition, and for regulating the electric flow inside the bulb during normal operation.
When we speak about LED lamps we actually mean LED luminaires that today are mainly of two types: SMD and COB.
LED (or light emitting diode) is a light source based on a semiconductor diode. When it is on, the electrons are able to recombine with the “holes” inside the diode, releasing energy in the form of photons: this effect is called electroluminescence.
Both SMD and COB are made of different diodes, however the COB has a single circuit.
ANSI Lumens only make sense when speaking about projectors or digital displays.
A measure expressed in lumens is meaningless for gobo projectors, as this article will show.
