Illumination
technology uses 2 dimensional waveguides to realize LED lamps or
shining advertising spaces. They can be made from every transparent
material with scattering particels inside for light emission. Lamp
glasses made of glass with air bubbles generate a very pleasent
light impression.
The micro reflector inside the LED module reflects even light rays that
are emitted under bif angles to the optical axis into the 2 dimensional
slab waveguide. The coupling efficiency between LED die and waveguide
is optimzed this way.
As the coupling element is designed as heat sink, the module
doesn't require further heat sink elements even though it is operated
with 1W electrical power. If the slab waveguide is made of glass there
is an additional heat dissipation via the glass. Similar to the other
DieMount PowerLED products the system of LED die, submount, and heat
sink is an electro-optical unit that needs no further heat dissipation.
The LED module can be connected without the necessity to take care of
thermal heat dissipation. The connector system of choice for all
DieMount PowerLED modules is the edge card connector according to the
SFP standard. SFP connectors are used in volume for telecom and datacom
applications and are low cost as a consequence. Each SFP connector
comprises 20 contacts that can be used to privide seperate contacts for
LED modules of different colour. Even a temperature sensor and a monitor diode for brightness control is feasible.
Please find the details of the SFP connector system for power LED modules in the data sheet "
PowerLED SFP connector".

In
order to combine a group of LED modules in a LED lamp for operation
with 230V power supply there are suitable wiring harnesses available.
