Technical Notes
What is an LED?
LED stands for Light Emitting Diode, short luminous
Epoxy
diode. In contrast to conventional lamps like incandescent, halogen or discharge lamps, the light of LEDs
Chip
is generated in tiny electronic chips. These chips are Cathode
made of semiconductor crystals embedded in a
plastic case. This plastic case ensures protection
from environmental influences as well as improves
the photometric properties. LEDs are regarded as
extremely long-life and efficient, due to many different
types and light colours they are suitable for a great variety of applications.

The light of an LED
In the p-n-junction or depletion layer (an area within the chip) the light is generated. The
process is called electro-luminescence. Depending on the semiconductor material the colour
appears, there are LEDs in red, yellow, green, orange and blue.
White light
For the generation of white light with LEDs, there are
two different possibilities. First, the blue light of an
LED is transformed to white light by luminescence
conversion like in fluorescent lamps. For this process
a very thin film of yellow phosphor material is applied
to a blue LED chip. The second method, however,
generates white light by additive colour mixing. There,
a minimum of three LED chips is needed, at least red,
green and blue (RGB).

Luminous diodes distinguish themselves by an
Spectrum LED (warmwhite/ 3 000K)
extremely long service life. But be careful: when the
temperatures are too high this service life can be shortened dramatically. So, for a long life
optimal thermo management must be applied. Service life of LEDs is mainly defined by loss of
light (degradation) during the burning
hours. Due to material fatigue and
other influence factors an LED looses
light during its life cycle. In most
cases, the time when light is down to
70% is quoted as service life.
Failures, however, cannot be ruled out
hours of operation
as impossible.

Luminous Efficiency
How efficient a light source might be can be described by the luminous efficacy (lm/W). Highly
efficient LEDs achieve luminous efficacies of more than 100 lm/W even today and so belong
to the most efficient light sources. Luminous efficacy depends on many factors: design and
generation of LED, optics (lens and reflector), ambient temperature, ballast, driver and many
more. The main focus must be put to the temperature of the chip. Similar to the span of
service life, luminous efficacy goes down with rising temperatures.
Thermo Management
For their efficiency and longevity LEDs need to get the generated heat out of the chip
and release it to the environment. How good this process works is determined by thermo
management. The LED itself is referred to a cold light source. This means, that there is no IR
radiation in the light bundle. And not, like many people would think, that it would not generate
any heat, on the contrary. How much heat it produces depends on power and efficiency.
Light Distribution
LEDs originally offer directional light due to the casing design. This property makes
luminous diodes interesting products for all kinds of applications where things
depend on precise illumination.
