The Cree XLamp XM-L2 U2 in cool white on copper round PCB!
The massive copper PCB has an outstanding and fast heat dissipation. A further advantage is the direct connection of the LED base with the copper. This contact is possible because of a special open area in the dielectric and increases the PCBs efficiancy even more.
The back
side is holohedral golden. This was made to avoid possible oxidation and
makes it easy to remove residues of additives or fingerprints.
The
XLamp XM-L LED is the industry’s highest performance, single-die white
lighting-class LED. XLamp XM-L is 20% more efficient than XLamp XP-G at
the same current, and can deliver 1000 lumens with 100 lumens per Watt
efficacy. The XLamp XM-L LED offers Cree’s industry-leading features:
wide viewing angle, symmetrical package, unlimited floor life and
electrically neutral thermal path.
XLamp XM-L LEDs can enable LED
light into new applications that require tens of thousands of lumens,
such as high bay and high-output area lighting. XM-L is also the ideal
choice for lighting applications where high light output and maximum
efficacy are required, such as LED light bulbs, outdoor lighting,
portable lighting, indoor lighting and solar-powered lighting.
Successful usage of high power LEDs:
Heat management
Applications with high power LEDs need enduring, adequate and plane
heat conduction from the first moment of use. It is very important and
neccessary to get the heat off the devices to ensure the maximum light
output, lifetime and efficiancy.
Drive management
LEDs should be run with a constant current in addition to the
manufacturers recommendations. To ensure this we recommend to take
constant current power supplies because resistors are always a risk
factor in high power LED applications.
IP protection
Unless otherwise stated, the modules are not protected against high humidity or splashing water. If LEDs are used in areas that require increased protection, this must be manufactured according to the requirements.
EMC protection
LEDs are sensitive against heat and electric charge. Please avoid any
kind of short circuits or electric discharge to the illuminant. The chip
can be damaged or even destroyed.
Storage / JEDEC level
The storage temperature should be from -30°C up to + 80°C in dry
ambience. After opening a sealed bag the content should be mounted
rapidly. Once absorbed humidity can be removed by tempering the LEDs in
some cases. More information can be found in the manufacturers
datasheets or on the manufacturer homepages.
Soldering conditions
Each LED has its own soldering conditions that the user should pay
attention to. After the launched lead free processing specifications
many standarts have changed. Information about recommended soldering can
be found in the manufacturers datasheets or on the manufacturer
homepages.
