Lumiled LUXEON LEDs belong to the worlds brightest high power LEDs and most popular solutions for evey application based on semiconductor illuminants. Even white LEDs generate more than 20lm. This is more than ten till twenty times more than a common 5mm LED does. The light concentration is even 5-25 times higher.
Please note
You should fortified take care of the different selections (bin codes) od the LEDs. For example: White LEDs of Rank "Q" have a luminous flux of about 30 till 40lm and rank "M" only about 14 till 18lm (@ 350mA). These differences and the later light efficiency of your application can thereby highly fluctuate. The low forward voltages (Vf) assure a low development of heat that benefits a maximum live time of the products. Please do never run applications with luxeon LEDs without constant current power supplies. You can find those right here. If you have any trouble with this subject matter or need a special rank just send us an email.
Comparability
We have often been asked how much MCD a Luxeon LED may have. This offered LED has the aboce mentioned MCD values at a viewing angle of 10°.
Application area
- Signal installation (traffic lights) - Any kind of ambient lighting - Any kinf of effect lighting - All application where a maximum of light is needed!
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.
