Across the globe, many countries are
shifting toward LED lighting because of its advantages of lower wattage demand,
lower maintenance cost and longer lifetime it offers. Even though the initial
cost of installing outdoor LED lighting can be substantial, it can save a lot
of energy for us. For example, about 200,000 street lights will be replaced by
LED bulbs in Denmark itself, which are likely to save municipalities 70% on
their energy bills. Nowadays, we use LED lighting for household lighting and
industrial lighting such as the lamps, the light for vehicle, the work light
for operation.
As the more energy-efficient illumination
options for consumers and industrial users, the demand of LED lighting has been
increasing in these years. Many governments successfully passed a series of
domestic policies that serve to not only stimulate LED lighting demand, but
also to improve LED lighting mechanism. Countries with the most advanced
economies such as the United State and Japan have well-established plans and
programs to phase out legacy incandescent lighting. Chinese government proposed
to spend 2.2 billion RMB on the promotion of CFL and LED lights, and to
prohibit the sale of 100 Watt-and above incandescent light bulbs, along with
those of halogen lamps whose efficiency levels fall below required standards.
That shouldn't be surprising, because the global lighting account is about 25%
of the total energy consumption.
LED lights are affordable for many
customers and industrial users now. The prices of low-end and low-wattage LEDs
that are produced in China have reduced by nearly half in the last one year.
Higher-wattage LEDs that are produced in other regions of the world have also
reduced by 15 to 20%.
So far, China, the largest LED lighting
market in the world, do not have good reputation in other countries. Large
buyers warn that the low-priced LEDs and LED lights produced by the Chinese
manufacturers usually burn out after less than a year. According to industry
experts, the Chinese manufacturers are still using outdated machinery and
equipment, which is a major cause for low quality of LEDs and LED products.
With the rise in demand, Chinese manufacturers have started ordering new
equipment from western suppliers early this year, which would soon improve the
quality of their products, and hence, their reliability.
LED lighting technology has been in
progress all the time. Since the invention of the blue LED, professor Hiroshi
Amano, Nagoya University Graduate school, was awarded the Nobel Prize On
January 14th,2015. Red and green LED have been appeared for a long
time, with the appearance of blue LED, we can produce a variety of colors of
LED lights. Professor Amano said,” I want people around the world can afford
LED lights, but the current price is still very high for them. If the
production costs will be reduced to one-fifth of today, the popularity of LED
lighting products will ultimately be greater than it is now. ”
