The Cobra 25 modules are characterized by a very low supply voltage (Uf).This
allows the use in projects with limited Uf, as well as the achievement
of almost every other Uf by series connection of several Cobra 25
boards.Thanks to the solid copper core base currents of typ. 3A up to max.5A are possible!Please note our information on thermal management.
areas of application are very light-intensive applications in which
the light distribution is to take place in any desired form over a
certain area.The shape of the Cobra 25 boards offers ideal conditions for CLUSTERING and CASCADEABILITY.
- low forward voltage (similar to standard high-power LEDs) - Realization of light intensive applications in the SELV range - best possible thermal properties due to copper core base
Solderless PCB with sockets for rigid strands (0.2 - 0.75 mm²).
The Samsung LM301B is currently one of the most efficient LEDs on the market and exceeds the 200lm/W limit.
feeding without soldering! The insulated conductor is simply inserted
into the clamping point as far as it will go and automatically fixed
securely. Please use solid and stripped wires.
Successful usage of high power LEDs:
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.
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.
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.
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.
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
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.
