Six puzzles in the management of urban road lighting

Abstract: in recent years, there are many lighting industry hot words, such as "city lighting" and "conservation priority" and "green" low carbon "LED industry" and "ten" city lights "contract energy" and "sustainable development" and so on, have attracted much attention. However, with the extensive application of LED lighting products, LED market has become large and complex products, energy saving of LED not only uneven in quality, excellent has not been embodied, even let people misunderstand LED lighting products. What kind of products to meet the technical needs of the owners? To meet the maintenance management needs of lighting managers? Meet the existing production capacity of enterprises?

In March 28th, the "light with the same way" city and light road lighting LED technology seminar held in Changzhou. At the meeting, Mai Weimin, director of the Changzhou urban lighting management office, as the first expression of urban road lighting owners in the end what? Express their views.

Mai Weimin said, according to the 2005 --2013 of the country's 22 provinces, 5 autonomous regions, 4 municipalities, a total of 977 city lighting management unit feedback data, in 2011, LED lighting in the city road lighting applications accounted for only 4%, only 8.3% in 2013, a large family can be very satisfied, of course, to today's data may be increased, but I want to say is that we as owners of units for good products is always maintain a positive attitude.

At the same time, he also stressed that the lamp maintenance free, does not mean that the lighting system maintenance free! Distribution, pipe, cable, hand hole covers, foundation, lampposts, lighting in the city lighting management work including (32), lamp maintenance accounted for only 10%, so we need more stable and reliable products to support our work. And in recent years, we are in the case of personnel funding, inadequate maintenance, stable and reliable lighting to make our demands, we must be actively promoted. As a street light management unit, we are also actively promote the LED part.

However, from the beginning of the application of LED road lighting until today, as urban road lighting managers are still confused. In this regard, Mai Weimin expressed his work actually encountered confusion:

Confusion: LED street lamps, all kinds of Nothing is too strange. Let our staff are accustomed to high altitude operation, the custom of 32 years of warm high-pressure sodium lamp warm light, we are accustomed to a single standard, simple structure, low maintenance cost of traditional lamps. For the rapid development of LED lighting structure, we need what kind of structure, we can get a stable and reliable lighting quality. One of the maintenance free, is the whole lamp? Or chips?

Confused two: often listen to the LED high pressure sodium lamp 200W lamp can replace 400W, this data is how to measure, is not new LED lamps with many years old lamps were compared, the comparison is scientific? Whether you are the light source efficiency is greater than or equal to 140lm/w and the energy efficiency ratio of the whole lamp.

From the light point of view, in the end how many watts of LED street lamps can replace 400W, 250W, 150W high pressure sodium lamp? In other words, how should we scientifically evaluate energy efficiency objectively?
