White LED LGP- professional and last generation component , STAR-LUXEON, LONG LASTING POWER, this item is new on the market. At today, this are the most efficient LED systems on the market. White LED STAR-LUXEON with high luminous power have very less energy consumption (less than 20mA), similar to a standard LED, with a luminous power 100 times more than a standard LED. The ideal solution for those who want a very intense light with a low energetic consumption, to develop a light-solar torch, if you want to have a intense luminous power for all application, this is the product for you.
This led system is a high quality system, not found on low- market cost..

Ideal solution for:

Ligh home installations outdoor/indoor, they has a intense but comfortable light, this is for the concentrate light beam of 120- degrees.
Tuning applications, for car/motor, Light systems of indoor/outdoor, position lights, handle lights, rear mirrors, bumpers, car interiors ecc.
Byke illuminatio, ideal solution for head and back of bike with batteries, beacause of low energetic consumption they have a long duration even if with a low capacity battery.

IN ADDITION:

- Underwater
- Boat
- Hobby
- Modelism

THIS LED IS THE IDEAL SOLUTION FOR ONE-DIRECTED LIGHTS, TORCH OR LIGHT SPOT, BECAUSE OF THE HIGH CONCENTRATED LIGHT DIRECTION,OF 20- DEGREES.

Major advantages of LED light in the illuminotechnic field:

- Operative Life (high emitting LED has up to 50.000 hours, reducing of 20% the electricity power - If- we can reach up to 100.000 hours);
- No repairing costs;
- Low energetic consumption (compared to standard alogen and incandescence lamps);
- Clean light because don- t have IR e UV;
- Easy made plastic system for lightning;
- High flexibility in installing the ligh spot;
- High saturated colours;
- High spot effect (this is a pointlike source of light);
- High secutity, beacause a LED system works on LOW tension (normally between 1.8 and 3.7 Vdc);
- Cold starting (up to -40°C) without problems;
- No sensible to wet and vibrations;
- No mercury added;
- Low energetic consumption (electricity intensity mA).

In many cases LED are powered by continuous current, with in series resistance Rs for limitino the current to work value, that can be vary from 5-6 mA up to a 20 mA when is required too much luminous power. This value depends also from the wave-lenght of the LED system.

You have to use this also bacause this will assure a long lasting life to the LED. If we didn- t have that resistence, a little increase of the work current will be dimuish the differential resistance of the - light - emitter diode" as we can see in the tension/current graphic. These variations, if enough high, could be cause a negative differential because the progressive diminuishing of LED resisteance will be cause (powering the tension as normal) the increase of the current and a simple Joule effect heating that will burn the LED.

We can evaluate Rs with Ohm law, with If current value, land Vs power tension and the difference of Voltage at work electricity intensity, Vf .

In detail the formula necessary for estimation is:

Example:

Vs = 12 volt, Vf = 1,8 volt, I = 20 mA
Rs = (Vs-Vf)/If = (12-1,8)/0.02 = 510hom

LED difference of voltage Vf can be extimated in the datasheet with an electric power of 20 mA in the datasheet.LED will work only on a direst voltage, and a little increase of voltage could damage tham. Differently from the standard alogen or incandescence lamps: it- s enough 10% less for not operating amd 10% more for damaging them.

Conventional LED are composed of variour inorganic materials wich has the following colours:

AlGaAs - red and infrared

GaAlP - green

GaAsP - red, red-orange, orange, and yellow

GaN - green and blue

GaP - red yellow and blue

ZnSe - blue

InGaN - green-blue, bluev
InGaAlP -red-orange, orange, yellow and green

SiC subtrate - blue

Diamond (C) - ultraviolet

Silicium (Si) substrate - blue (in develop)

Sapphire(Al2O3) as substrate - blue

In addition, Tension dropping LED is related by the colour, as follow in the table:
