When connecting LED light engines
and driver boards, there is a wide range
of choices for connectors. Ideally, the
connector chosen for street lighting
applications will allow for some modularity
without sacrificing robustness and ease
of installation. Modularity can be essential
for LED streetlight designs, as a given
driver board could be used to drive several
different LED light engine boards, but
each board may be of different sizes and
dimensions. To save on multiple designs and
board layout/assembly costs, hermaphroditic
board-to-board connectors can be used
Hermaphroditic connectors can allow for
lighting construction that uses numerous
boards chained together to be easily
assembled without concern of keying or
orientation, also easing assembly.
Conclusion
LED Street lighting is the future of virtually all street
lighting applications. From dense metropolitan areas
and high traffic tunnels to suburban walkways and
rural roadways, LED lights are gradually replacing
high-pressure sodium/low-pressure sodium (HPS/
LPS), incandescent, and mercury vapor bulbs
worldwide. LED lights' greater efficiency and flexibility
are the main factors driving this trend. However, with
the additional flexibility and options that come with
LED streetlights, including color temperature, light
fixture design, dimming, etc., also come other design
considerations. The choices of LEDs, LED light engines,
drivers, and interconnect can significantly impact
the overall cost of the street lighting installation,
maintenance costs, and OpEx. ■
