How To Make The Most Effective And Compact LED
Drivers? - Miracle Electronics
Theres a rising need of small and smart LED
drivers for the myriad of smart applications
that are being used today. But, it is also
important that these small smart drivers are
efficient and reliable, while also being
cost-effective. So, how is all of that possible?
With the rising need of small LEDs, a variety of
LED manufacturers have begun using matured LED
component technology to build small efficient
LEDs. But, not every manufacturer can build all
of it in a slim, sleek, and aesthetically
pleasing lighting fixture design. This is because
the LED driver industry has been slow to adapt
and provide high power density drivers, which
has limited the creativity and imagination of LED
lighting fixture designers.
High power density means the drive shrinks in
size, while maintaining the same power output.
But, achieving such high power density is
challenging as with the rising power density, the
power level of the driver drops too. Moreover,
EMI compliance and basic safety isolation
requirements are fixed, and occupy available
space quickly at lower power levels. So, how can
you

achieve power densities that are seemingly
unattainable? Below mentioned are some key
factors that can help. Mechanical size
reduction The most compact version of every
component needs to be used, without compromising
on performance. In fact, certain components
should also be customized based on the desired
density and shape. Topology and IC design With
the right kind of topology and IC design, the
number of components must be reduced, so as to
reduce the size and cost of the driver. But, in
the process, the driver performance and
reliability must also be maintained. Integration
Despite the higher costs, the latest and most
integrated ICs from reputed IC manufacturers
should be used, because integration is a huge
factor for size reduction. 3D design
techniques Using 3D design techniques can
dramatically minimize the amount of empty space
left on the board and within the driver housing.
Minimizing the noise path and optimizing the flow
of energy through the converter can help with a
successful high density design.

Thermal aspects With the reduction in driver
size, the contact area of the driver to the
heatsink also shrinks, thus transferring lesser
heat to the heatsink or chassis of the LED
lighting fixture. Innovative circuit designs
should be used to reduce the thermal load of the
driver. Moreover, the sensitive components of
the driver should be kept as cool as possible
with the right thermal design techniques. For
instance, a fully utilized driver contact surface
allows a smaller thermal contact surface to be
required to achieve the same case temperature.
Hence, sound thermal design considerations must
be used to effectively transfer heat from the
driver and LED board into ambient air. The lower
the Tc, the longer the lifespan of the driver,
and higher will be the reliability of the
system. Miracle Electronics is one such supplier
who uses lean manufacturing techniques that can
help maximize product efficiencies with
constantly improving processes. This is possible
because of the enhanced knowledge and experience
of the operators in the Miracle Electronics
team, who help make the company capable of the
best and most reliable programmable power supply
