Technical assessment of light emitting diodes
(LED) lights for street and parking lot lighting
applications. Recently, there have been
significant improvements in the cost,
performance, and application of LEDs for a
variety of lighting applications. The energy
saving potential of LED lighting, as compared
with conventional lighting, ranges from 50 to 90
percent. Additionally, LED lighting technology
offers benefits of extended operating lifetime
(up to 100,000 operating hours), small sizes to
expand fixture design options, and improved
optical quality and control.
Low Power
Requirements. LEDs require low direct
current voltage and low power to operate. This
ultimately results in reduced energy use. In
many applications where LEDs are used today the
energy savings are at least 50 percent, and up
to 90 percent for applications where they
replace incandescent lights. Energy and cost
savings associated with the use of LEDs in
traffic signals are approximately 90 percent.
Long Lifetimes. LED manufacturers
claim lifetimes of up to 100,000 hours (with
less than 40 percent lumen depreciation after
100,000 hours of operation). This is several
times greater than the operating life of
conventional lighting. Because LEDs may last
more than 10 years, replacing lights that are
difficult or costly to access are good candidate
applications for LEDs, such as towers, aircraft,
offshore buoys, tunnels, and bridges.
Color Rendering. LEDs are capable of
producing light that provides an accurate
rendering of object’s natural color. LED
products for street and parking lot applications
have been designed to produce a warm, white,
light that range from 85 to 90 (on a scale of
100) on the color rendering index (CRI). This is
very good especially compared to other lights
commonly used these application, such as high
pressure sodium (CRI of 20 to 80), mercury vapor
(CRI 20 to 60), metal halide (CRI of 60 to 80),
and especially low pressure sodium (CRI 20 to
60) whose yellow color makes it difficult to
discern color difference in objects.
Small Size. LEDs have been referred to as
the ultimate light point source. This offers
product designers and integrators flexibility in
their form and design for a wide range of
products. LEDs in the miniature lamp market,
such as use in automotive panel display lighting
and rear cluster (red) lighting, is well
established and growing. The small LED size also
allows mixing of different colors in small areas
for meeting specific optical needs.
Optical Control. LEDs offer the benefit of
greater optical control due to their small size
and packaging options. When combined with a
well-designed fixture, the
light produced by LEDs can be directed to the
intended location such as a roadway surface.
Typical fixture losses are in the range from 40
to 60 percent, meaning that only about one-half
of the source light is directed in the desired
direction. LED fixture efficiencies can be in
the 80 to 90 percent range. Thus, an LED light
output does not have to be as high as a
conventional light to achieve the same coverage.
This makes LEDs advantageous for streetlight
fixtures to minimize light trespass to adjacent
areas not intended to be lit.
Operating Characteristics. LEDs have several
favorable operating characteristics. The lights
do not require any “strike” time – they
instantly come on and off – and on/off cycling
does not affect lifetimes. As LEDs fail, they
dim rather than turn completely off or cycle
on/off as with other lighting.
LED are resistance to vibration, a key
attributes in the automotive market. Also, LEDs
are dimmable and operate without generating
excessive heat.

Intelligent current control, achieve the precision
constant current: Each LED module can implement intelligent current control,
whatever power network how to wave, it is able to achieve the precision constant
current, ensure the LED can work under the secure curren.
No Strobe Flashing: Eliminate the visual fatigue which
caused by the strobe lights of the traditional tunnel lamps.
Perfect Support intelligent control: such as combine
Tunnel lighting starts shortly as trait(<2 seconds), Adopt the newest technology
of tunnel lighting intelligent control, when no vehicles pass tunnel, It can put
out most of lamps, when vehicles pass tunnel entrance at within 500m area, It
can start lighting automatically. So It has solved the problem of smaller tunnel
traffic which no vehicles pass the tunnel will waste a great deal of electric
power sources. Supply a new idea “establish saving society” to city road
