LED LAMPS

How to save energy while having better light quality? Most people know about low voltage bulbs, unfortunately they are still not very com-mon, and are far more fragile than there more traditional counterparts. There is also a less well-known technology: LED lamps. They started there life in the mass market where effective light was needed with low voltage such as home garden solar lights, flash lights, but also to replace light sig-nal and in cars. One now finds these LED lamps in our houses to essentially replace halogen spot-light. The advance tech-nologies in the area en-able to ensure high qual-ity, fully recyclable solu-tion, significantly im-proving lighting condi-tions and Health & Safety in offices, build-ings and public spaces.The economic and eco-logical advantage is without equivalent, be-cause the consummation of these lights only rep-resents a few Watts, it is nothing compare to halogen or any other technologies. Further-more they have a quasi-infinite life expectancy and thus a further ad-vantage for the envi-ronment and controlled recycling.

The LED of power

A LED is a semiconductor (diode) that produces light when 3.5V is reached. It emits a pure

light (monochromatic) and its colour depends on the type of impurity willingly introduced in the silicon. The white is classified in nuances spanning from “warm-white” to “coll0white”

(the light efficiency diminishes with the temperature of the white)

Power supply of the LED of power

The LED of power are powered in DC current coming from and controlled with precision by an inverter. A too high current would destroy the LED light in a few seconds and too weak

current provide an insufficient yield. The connection in series of all LED assure a constant current. A parallel connection (like halogen light) would destroy the LED in a very short time.

Comparing between LED of power with 12V halogen Lights

When one speaks of light, Watts of the different lights is wrongly used as a yard stick. The

Watt power indicates the energy consumption or absorption, but it doesn’t indicate the light yield. We need to consider the lumen (lm) which is define as the quantity of light emitted,

and the lux (lx) that indicates the quantity of light received by a surface. The relationship

between absorbed power and the light emitted results in the light yield and is expressed as lumen per Watt (lm/w). This value indicates the quantity of light emitted per unit consumed.

For example, the light yield of a 12V halogen light is of about 13 to 15 lumens per absorbed Watt; therefore a 10W halogen would produce a powered light about 130 lumens (13 lmx

10 W). The 1W LED of power has a yield of 39 lumen per absorbed Watt, a spotlight with 3

1W LED would have a powered light of 117lm (39 lm x 3W)

General Remark

The length and diameter of cables are not par of the critical parameter, however as men-

tioned previously, the current is constant and the value are very low: 350 …. 700 mA. The

constant current doesn’t generate any electromagnetic emission, and the length of the ca-bles can reach 30m. The eventual loses can automatically be compensated by the inverter.

The invertors have to be installed in ventilated areas and not close to heat sources so that there components are not deteriorated by any heat.

All invertors comply with the European norm EN60347.
