Street lighting is an important part of the city, often used the
traditional high pressure sodium lamps, high pressure sodium lamp
shortcomings of low overall polishing efficiency caused a huge
waste of energy, therefore, the development of new high efficiency,
energy saving, long life, high CRI, environmental protection street
lamps lighting the city with a very important energy conservation.
In recent years the rapid development of LED lights in the domestic
market size has been expanded. 1, LED lights its own characteristics - the way of light, there is
no diffuse light and ensure the efficiency of light;
2, LED lights have a unique secondary optical design, LED lighting,
street lamp light shines on the area needed to further improve the
light efficiency to save energy;
3, LED light source efficiency currently stands at 90-110lm / W,
but there is still much room for development, theoretical value of
250lm / W. The high pressure sodium light-emitting efficiency is
only increased with the power to increase, therefore, the overall
light efficiency LED lights stronger than the high-pressure sodium
lamp; (the overall effect is the theory of light, in fact, more
than 250W high pressure sodium light efficiency than LED) .
4, LED street light color than the high-pressure sodium lamp is
much higher, high pressure sodium color index is only 23, while the
LED lights color rendering index of 75 or more, from the visual
psychological point of view, to achieve the same brightness, LED
street lamp illumination average of 20% lower than the
high-pressure sodium lamp above (see the British sense lighting
standards);
5, LED street lamp light is small, one-year decline of less than 3%
of light, the use of 10 years still to road illumination
requirements, and decline of large high pressure sodium lights,
about a year, has fallen more than 30%, therefore, LED street lamps
in the using the design of power than the high pressure sodium
lamps can be low;
6, LED lights with automatic control of energy-saving device, to
achieve different times to meet the lighting requirements in the
case of the maximum possible reduction in power to save energy
7, LED is a low-voltage devices to drive the voltage of single LED
safe voltage power products are all single 1 watt LED, so it is a
more secure than the use of high voltage power supply, especially
for public places (such as: street lights lighting, factory
lighting, automotive lighting, commercial lighting, etc.)
8, each unit is only a very small volume of small pieces of LED, it
can be prepared into various forms of devices, and for the
environment variable.
9, long life: more than 50,000 hours can be used to provide three
years of quality assurance. Inadequacy is the power of life can not
be guaranteed.
10, high light efficiency100LM used more than chips, compared to
conventional energy-saving high-pressure sodium lamps to more than
75%.
11, installation is simple: no rectifiers without Jiamai cable
directly to the street lamp poles connected to or installed in the
original nest lamp will light shell.
12, thermal control, well: the summer temperature at 45 degrees
below, and passive cooling methods, lack of summer heat protection.
13, reliable: the power circuit used in all high-quality
components, and every single LED has a separate over-current
protection, without fear of damage.
14, light-color uniform: without lens, not to increase the
brightness at the expense of uniform light color, no aperture in
order to ensure uniform light color.
The principle of comprehensive, high-power LED street lamp energy
saving effect is remarkable, instead of high-pressure sodium lamps
can save 60%. To be elegant
Low maintenance costs: Compared with traditional street lights, LED
street lamp maintenance costs low, by comparison, less than 6 years
to recover the full cost of inputs.
