Lumex QuasarBrite™ 4-Leaded RGB LEDs
With a market-leading thermal design, the
new QuasarBrite 4-leaded RGB LED combines
a compact package size and an in¬novative
lead frame design for outstanding heat
dissipation. Additionally, the off-the-board
design allows for an increase in convection
FEATURES:
 120˚ viewing angle (versus a traditional 30˚
viewing angle from other through-hole
LEDs)

not seen in most standard products. This
product boasts a wide view angle, 120˚, not
typically seen in through hole products. This
set up is ideal for applications that require a
matrix of high intensity output with a wide
view angle that maximizes pixel pitch in
indoor sign applications.
Microchip’s New Digital LED Lighting Development Kit Makes it Easy to
Add Intelligence and Improve Efficiency in LED Lighting Applications
Free Reference Design and dsPIC33 ‘GS’
Family of Digital Signal Controllers Helps
Lower Product Costs, Reduce Size and
Improve Eciency
Microchip new Digital LED Lighting
Development Kit helps LED lighting designers
who are challenged to meet the rapidly
expanding demand for green, smart energy
technologies while dierentiating their
products. This development kit enables
designers to quickly leverage the capabilities
and performance of the dsPIC33 ‘GS’ series of
Digital Signal Controllers (DSCs), to develop
LED lighting products. The dsPIC33 ‘GS’ DSC
and this reference design
allow developers to create
a 100% digitally controlled
ballast function, while
including advanced features
such as dimming and color
hue control. The dsPIC33 ‘GS’
DSCs can support an entire
system implementation for LED
lighting products, including
power-conversion circuits, such
as AC-to- DC and DC-to-DC
conversion, along with functions
such as Power Factor Correction
(PFC), which are necessary for
a complete product and lower
the overall system cost.
This reference design enables our customers to
develop LED lighting products that are 100%
digitally controlled and are very cost eective.
By using the exible dsPIC33F “GS” series of
DSCs, customers can easily customize and
dierentiate by making simple modications
to the control software.
Benets oered by the digital-power
techniques in this reference design and the
dsPIC33 ‘GS’ series of DSCs include:
• Reduced System Cost via higher integration
Microchip
• Higher Eciency using digital-control
techniques
• Flexible and reusable designs
• Advanced features implemented in
software
Additional key features of Microchip’s Digital
LED Lighting Development Kit include:
• Color control for RGB LEDs
• Flexible input voltage support, including
both Buck and Boost topologies
• Fully dimmable
• Full digital control
• Fault protection
• Fully controlled with a single
dsPIC33FJ16GS504 DSC
LED lighting applications supported by
Microchip’s LED Lighting Development Kit
include dimmable LCD backlighting, signage,
LED replacement of uorescent tubes and
incandescent bulbs, architectural lighting, and
automotive lighting applications. Automotive
lighting products include exterior applications,
such as headlights, daytime running lights and
signal lights.
