Optical warning devices inform of a condition or danger or alert in industries, infrastructures, transport, etc. and can be used to highlight buildings or monuments.
A2S optical warning devices meet the needs of the most demanding applications.
Types of lamps
Incandescent lamps:
A tungsten wire , subjected to high temperatures, emits light energy over a broad spectrum.
Halogen lamps:
We use a glass body (smaller volume than conventional bulbs) by filling it with halogens (iodine, bromines). The deterioration of the filament is slower, which gives a constant or even higher yield.
Xenon flash tubes:
By applying a sufficiently high voltage in a glass body filled with xenon, this results in a very intense light pulse.
LED:
LEDs (Electro-Emitting Diodes) are optical semiconductors which transform an electrical voltage into visible light.
