LED integrated - SIRENA - #2

The advantages compared with devices with an incandescent bulb:

• FOUR YEARS GUARANTEE

Led integrated products are guaranteed for four years from the date of production indicated on the product.

• LONG LIFE

Led bulbs, unlike filament bulbs, never burn out. The light in­tensity decreases by 5% after 100.000 hours operation (a measurement that is verified by means of an instrument only) -the human eye perceives a difference when there is a decrea­se in the region of 15%/20%.

• LOW ABSORPTION

The current absorbed by a led integrated product is much less than that of an equivalent device fitted with a filament bulb and is, therefore, energy saving. This characteristic makes these products ideal for use in logic plants where there is a PLC or computer controlled machines.

• NO MAINTENANCE

A led integrated product requires no maintenance: the piloted electronic circuit is embedded in vibration proof epoxy resin from which the led emerge.

• RELIABILITY OF THE DEVICE

The mechanical characteristics of the epoxy resin circuit fitted in led integrated products are superior to that of the thin wire of a tungsten bulb and these products are therefore extremely more reliable.

• NO HEAT

Led bulbs emit cold light and, unlike incandescent bulbs, there

is no energy used to heat the bulb: a led integrated product is therefore energy saving and is more environmentally friendly. m

• CLARITY OF THE SIGNAL ^ The light emitted by an incandescent bulb is a mixture of wave­lengths of all the colours in the range. The light is filtered through • the dome and the onlooker identifies a definite colour with sha- 0 ding of other colours. The light emitted by a led bulb is concen- A trated on one wavelength only and there is no filtering as the colour of the dome is the same as that of the bulb. The result is

a clear signal that strikes the onlooker as the human eye is not 9 used to such a pure coloured light. It is emphasized that the £ LEDS used in these devices are extremely bright. a

• PRODUCTION QUALITY

All led integrated products are submitted to a parametric test at ™ the end of the production cycle. The result is printed on a test 9 certificate and packed inside the box. Q

• COST = ZERO — Even though the initial cost of a led product is more than that of ~ the traditional version it is of no significance because the energy 9 saving within the guarantee period completely outweighs the ini- £ tial extra cost.
