All over the world set off LED wave, LED lighting as a new favorite what are the characteristics of it, and what are the disadvantages, we will talk about them one by one.

After the installation of a single LED lamp, brightness and color can be adjusted to meet the needs of business district, residential area and the park, even if different seasons can be converted. Central maintenance equipment can be monitored by wireless technology to turn off the lights. LED lights can be designed to blink during emergency events, or as a guide in special events.

LED uses less energy than traditional light bulbs, while life expectancy is 4 times longer. And the traditional lighting in 7 to 3 years of renovation costs will be more than the original cost.

But in addition to a large number of advantages, LED lights also exist problems. Although the purchase price of the LED lamp has been falling, it is still much more expensive than the traditional light bulb. There are dazzling lights, lights of invasion and influence of motorists and pedestrians, cyclists and other defects. The first street renovation equipment also has a lot of inconvenience for the LED lamp.

Pittsburgh plans in the next 5 years will be converted to LED 40 thousand street lamp. The city's appointment of the Institute of recycling city of Carnegie Mellon University to analyze the possible negative effects of LED. The Institute of international best practice benchmarking, research the latest LED technology, leading the field operation test, interview stakeholders, and ultimately to the government to make recommendations.

The result of the study is that the dazzling glare of LED is particularly harmful to people with visual impairment and age related visual impairment. Police also said it was difficult to observe the activities of half a block away. However, these issues can be resolved by appropriate design guidelines and specifications.

Reconstruction of City Institute of the project began to design standard lamps of two main types: high pole lamps for the drivers and riders to illuminate the road, and the sidewalk for pedestrians increase low lever lamp brightness. "We propose to abolish the global lighting standards in Pittsburgh, including the oak type high pole lamps and other pedestrian lamps illuminated in all directions, because the glare of the LED lamp is too oppressive. We recommend a shade of light downward lighting, and lighting up on the sidewalk near the horizon from LED light diffuse light." Project team researchers say.

In addition, in the manufacture of lighting equipment should be able to control the direction of the light shade as the focus, this makes the other direction at LED light is blocked, only stand under the lights to be shine. Light color can be adjusted in 2500 to 5000 between Kelvin and Kelvin, in order to adapt to the different needs of business and residential areas. The first batch of 3000 LED lamps will be completed in the first quarter of 2012 in the Pittsburgh business district.
