70x Samsung LM281B+ Backlight PCBs

The Samsung LM281B+ backlight boards offer you completely new possibilities to realize demanding applications.
Through the sockets you can easily extend your application almost infinitely. For the operation of the modules you only need a constant current power supply with sufficient power.

The backlight boards are for the areal illumination of e.g. advertising signs predestined and are only slightly heated due to the assembly density. Many applications can therefore be implemented without additional cooling.

The advantages at a glance:
- individually stackable
- high luminous flux
- 70x Samsung LEDs per board
- fast and easy handling through plug-in system
- easy installation
- optimized surface illumination, e.g. advertising space
- very good price / performance ratio

- ATTENTION! For use with constant CURRENT only!

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.

Delivery time

Deliveries within Germany take 2-3 days beginning after receipt of payment, for deliveries to invoice beginning with the shipment, for deliveries to cash on delivery beginning with receipt of order. Payments and incoming orders beyond our business hours let the delivery time begin with the next workday. For deliveries to other EU countries the delivery time may be extended up to 3 weeks. The delivery time is subject to the proper delivery of the logistics company, as far as delivery delays are not caused by us. The validity of the above delivery times requires the availability of the ordered goods from stock at the time the delivery time is beginning.
