Solar Lighting
and the New
Solar LED Lighting
All components needed for installation are
included (except for the mounting pole). The systems
are designed for installation onto a wood, concrete,
or metal mounting pole. You may choose to use your
own pole or we can quote the poles separately from
the lighting system itself.
These units can be used for: Area lighting,
Billboards lighting, Dock lights, Park lighting,
Parking lot lighting, Parkway lighting, walkway
lighting, Street lighting, Transit Lighting, Outdoor
area lighting.

Solar Powered, wireless Got
facilities you need to keep an eye on? Oftentimes they're several
miles from your headquarters and, worse, you can't get any
electricity (let alone Ethernet) to an exterior location where you'd
like to mount a camera. Companies with remote or hard to access
assets, such as oil and gas pipelines, bridges or rural properties,
have not had an effective, economical solution for protecting those
assets. |
|
Easy to retrofit LED streetlights can easily
retrofit existing metal halide,
high pressure sodium and mercury vapor luminaries.
Your next scheduled QLED maintenance will be in 5 to
8
years!
with our IQ Retrofit Lamps
IQLED Unlike bulb streetlights,
IQLED lighting
modules produce very intense light in tightly
control IQLED directions. There is no longer a need for
reflectors or cut-off shields to minimize light
pollution and trespass. With IQLED energy
usage less than 20% and lifespan more than seven
times that of conventional streetlights, payback
occurs very early in a long life cycle.
High
Power Led Tunnel and Subway Light:
Revolutionary Photometric Design-The world’s first
dedicated optical system(rectangular beam focusing
lens): Reasonable control of the light distribution,
spot rectangular bean pattern ,and ensure an ideal
uniformity of brightness on the road surface,
eliminate the glare and keep the LED lighting efficiency on a high level, no light pollution
|
|
Weatherproof for coastal climates
Vibration resistant for tunnels and bridges
Withstand 160 MPH winds
Saving energy and money.
The new IQ LED lens fixtures use less energy,
helping to keep operating costs down. After
three years, The City will regain the cost of
installing the new fixtures from energy and
maintenance savings.
Reducing greenhouse gas emissions. Using
less electricity reduces the emissions produced
by gas and coal-burning generators. When the IQ
LED Streetlights project is completed, carbon
dioxide emissions will be reduced.
Reducing glare to increase visibility.
Glare from street lights is significantly
reduced with the new IQ LED's street-light
fixtures, increasing visibility by directing
light onto the roadway and preventing it from
shining into the eyes of motorists.
Reduce excessive lighting and light
pollution. New ways of designing and
providing street lighting have been developed in
the last several years.
Maintaining a safe level of lighting. Street
lighting on residential and collector roads will
continue to meet minimum Illuminating
Engineering Society (IES) guidelines.
If your City is committed to
savings and reduce the level of light pollution
by using the most efficient IQ LED
street-light fixtures and employing the latest
design methods.
Hurricane Proof LED

High
Power LED Street Light: High Power Led Streetlight: Designed to eliminate glare, light trespass, and sky
glow, the LED street lights only shine light at
ground level. Multiple colors Temperature from 3000K
to 7500K are available, suitable for different area
and situation. The Power varies from from small
security yard, to Major road. The lamp applies high
power LED. Fine cooling system applied. The average
life time of the system can be high up to 50,000
hours, lighting 10-11 hours a day, the light can be
used for more than 11 years.
LED Tunnel Light
-
Tremendous Energy Saving: Used the ultra high
power, high brightness LED light source
,together with the high power efficiency power
supply, which can save energy 50%-80% than the
conventional sodium and mercury lamp
-
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

Transportation
Accessories:We
offer an extensive line of proprietary
precision-lenses signals that direct 90 percent
of all
light toward the
motorist, ensuring compliance with ITE, Caltrans, Energy Star and
many other state and municipal DOT specifications. Products include
red, yellow and green modules, using state-of-the-art, Hi-Flux LED
technology; arrows including the industry's first bi-modal unit; and
a variety of pedestrian signals.
Increase the public safety and reduced traffic congestion by
allowing
traffic lights to function even during a power failure. A
typical traffic signal intersection experiences eight to ten local
power outages annually. With IQUPS battery backup power, some or all
the traffic control signals can continue to operate. This seamless
switchover to battery power increases public safety and eliminates
the need to dispatch police or other service personnel to direct
traffic. If all traffic signals were converted to LEDs, the battery
backup system would allow full operation of the traffic signals
during a power outage, thus alleviating traffic congestion.

Power
The SPDC/AC unit was designed to be
easily expanded: power units can range from 2,000
Watts to 10,000 Watts. Its flexible platform design
allows it to be easily
customized for use with area
lighting, remote communications, security systems,
and surveillance equipment, to name a few
applications. Charge power alone can be
doubled or
tripled with the addition of simple, cost-effective
photovoltaic capture equipment. Pre-assembled & Factory Tested
