University
of Manchester is currently studying the advantages of LED technology used in
road lighting, The long-life
LED lights means less frequent replacement and maintenance, thereby reducing
the adverse impact on traffic, reducing the associated costs of replacement and
maintenance.
LED
lighting products are long life expectancy which are currently studying the
life of the LED lamp module is to reach 10-year, far than the existing ordinary
street lighting. In addition, the
use of LED lights to provide lighting can reduce 25-50% of energy consumption,
can save more energy and costs.
But
when the high-brightness LED at work may cause heat, which
can also affect the life span of LED lighting, also
makes the heat problem has become an obstacle to the development of LED. The
researchers are now faced with the question how will work closely together of
the LED at work generated heat
in a timely manner dissipate, to
extend the life of LED lights.
Since
the LED module is used in outdoors, the actual environmental factors have been
taken into account. Such as critical
heat sink is the possibility of a bird nest. Existing
regulations stipulated in the glare of the lights and light pollution degree
limit, while clearly defined area of the LED light source can be installed.
Under
normal operation, LED light output to go through the process of gradual reduction,
and this process will continues. Led
light output reduction may be due to reduced efficiency of light generated by
the LED, or the LED compressed within the optical path in reducing. However,
as long as no overload, LED lights after work 50,000 hours or 10 years, you can
reach 70% of the original light output capability.
