NXP & energy-efficient lighting

The lighting industry is undergoing a major transformation, driven largely by
concerns over climate change and the desire to use energy resources more
efficiently. Governments and consumers alike are setting incandescent lights
aside, switching to newer, more energy-efficient technologies like compact­fluorescent lamps (CFLs) and solid-state lighting (SSL). These new technologies
are, indeed, much more energy-efficient, but they’re also much more challenging
to design, since they require complex driver and control electronics.

That’s where NXP comes in.

Making it easy

As one of the first semiconductor companies to
recognize the growing importance of energy­efficient lighting, we’ve been supplying complete
lighting solutions to some of the largest and most
innovative lighting companies for more than 20
years.

Now, we’re opening up our portfolio, offering our
proven, highly integrated ICs for lighting control and
driver electronics to a much wider audience of OEMs
and ODMs. We’ve even established a dedicated
lighting group, so our customers get the optimized
solutions and detailed application support they need
to be competitive.

Offering integration and support

We’ve made lighting a strategic focus area and
devote a substantial portion of our R&D resources
to developing new ways to save energy and
simplify design. Our industry-leading GreenChip
ICs, for example, are the basis for many of our

lighting solutions, and bring new degrees of
power management to lighting applications. We
consistently set the bar for integration, finding new
ways to reduce form factors, and we offer extensive
support tooling, for the fastest, simplest design-in
possible.

Equipped for economies of scale

We offer large-scale production capacity and
support all the leading formats, including CFL,
SSL, HID, and TL. We apply the same best-in-class
technical and industry practices across the board,
no matter what the technology, so you get a full­service partner that delivers true innovation – like
dimmer compatibility – while simplifying your
logistics and reducing your supplier base.

This all means we can offer a complete range of
solutions for lighting control, from advanced, high­energy-saving integrated solutions, to cost-efficient
discrete solutions based on our broad range of
semiconductor components.

} Proven innovation } Proven efficiency } Proven reliability

The right technology for every application

We offer advanced, cost-effective control and driver
ICs for every application, from home and office to
retail and street lights.

Saving energy at home

In the past decade, CFLs have become a popular
choice for residential lighting. SSL is starting to
make its way into the home, too, and shows great
promise for the future. NXP offers cost-effective
driver solutions for both technologies.

Giving retail revenue a boost

Shop owners use lighting to draw people in and
show off the merchandise. They’re looking for
good, consistent white-color rendering that’s as
close as possible to natural daylight. Reliability and
longevity are also important, since they help reduce
maintenance and replacement costs. HID and
SSL are excellent choices, and NXP has innovative
options for both.

Making work spaces more efficient

Offices and industrial sites need general lighting,
localized lighting, and local task lighting. HF TL
fluorescent is an ideal choice, because its bright
white light and good color rendering minimize
eyestrain, while its consistent performance over
a long life reduces cost. HF TL can also dim light
in unoccupied areas, for added energy savings.
NXP has the right control functions for HF TL.

Keeping streets safe

Cities around the world are switching to low-energy
lighting for their street and highway networks.
Advanced dimming capabilities allow large areas
to be dimmed during quieter periods, for reduced
light pollution and added energy savings. Lights
can be set to brighten automatically when there are
cars or people present, so everyone stays safe.
HID and SSL are popular choices, and NXP has
energy-efficient solutions for both technologies.
