New aluminium round PCB with 4x CREE XR-E in R2 bin!
This product, containing PCB and already mounted Cree LEDs, has not been developed as usual in the market. It contains four instead of only three emitters which makes it 25% more powerful than alternative products. Because of this reason it reaches up to 968 lumen at 1000mA.
The small diameter of only 34mm make this PCB ideal for a huge range of applications like architectural lighting, mobile lighting solutions and many more. To bundle the enormous light output we recommend to use the especially designed 9° and 17° LEDIL optics which are also capable to MR11 mountings. Please note that the PCB needs adequate cooling. Useable coolers can be found in our Shop too.
High end SMD technology with fused quartz lense
Cree is one of the pioneers in the development and manufacture of extremely bright and reliable LEDs. The XLamps are up to 50% brighter than other products available in the market. The XLamp product family has integrated Cree High-Power LEDs with innovative SMD (Surface Mounted Device) packaging technology. The resulting product offers optimal conditions for light solutions on LED technology basis at an unrivalled competitive price.
What makes the XLamps special?
- Driveable up tp 1000mA
- Finest selections
- Low operating voltages
- Integrated fused quartz lense
- Dimensions only 7.0x9.0mm
- ESD > 2000V
Of course the XLamp series complies with RoHS criteria too. The PCB diameter is 20mm.
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.
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.
