===Full-automatic
environmental-protection street lamp electric saver ===
 Street
lamp electric saver is energy saving equipment based on intelligent
control technology. With special, advanced design, reliable hardware
and control software, it can automatically adjusts the switches of
street lamps at any moment according to the users’ requests.
Meanwhile it can constantly inspect and adjust the sine wave
alternating current with any high-pressure sodium lamps, hydrargyrum
lamps and metal haloid lamps equipped with inductive ballast. With
various protection degrees, it can be used in all kinds environment
conditions. Our products feature the main circuits composed by
special electricity saving loops, constant output current, no
harmonic wave disturbance to electric net, high reliability, strong
endurance of surge pressure impact and transient load impact. The
electricity saving effect is so remarkable that the equipment
investment can be returned in about one year. The product can be
used for 10 years and we guarantee the repairs for 3 years.
With a simple installation and no need to change customers’
original lighting system lines, our products can be connected
directly to the street lamp switch line behind the wattmeter and
before the lamp switch.
With delayed switch system and comprehensive intelligent
inspection, our products can prevent light bulbs from becoming
yellow or dark under the pressure undulation, prolong the usage life
of light bulbs, maintain the general harmonic wave on the electric
line, stabilize the pressure and lower the drift current.
With the safe “bypass” device, our products can prevent light
bulbs from affecting the normal pressure supply under equipment
failures. If there’s something wrong with Light Saver , it could be
switch automatically to a normal power supply operation.
Application objects: lighting system in public places such as
works, department stores, supermarkets, city avenues, squares,
highways, gas stations, docks, airports, etc.
As we all know, the electric pressure fluctuates according to
the peak and valley state of electric current, which has a
fluctuation range from 100v to 250v. The luminous intensity does not
increase with the feedback power to the lamp fittings. When the
pressure is below or above a certain value, the luminous efficiency
will descend. Beside the energy for illumination, the energy wastes
for heating lamp fittings and this is very harmful to both the
circuit and the light bulbs.
LJ-I Type street lamp electricity saving equipment can resolves
this problem through microcomputer’s real-time inspection, analysis,
calculation to find the best power point and have dynamic
adjustment.
The main circuit, with high reliability, does not include any
electronic element or contact, nor any rotation framework or
charcoal brush so that it can lower the repair expense and save the
repair work.
