Nights in big European cities are filled with red aviation warning lights for high-rise buildings. Large-scale landscape lighting is rare, so LED streetlights are chosen as observation points.
The proportion of LED streetlights in London, Manchester, Liverpool and Belfast ranges from 30% to 50%, and Dublin, Ireland, may be less than 30%. There is an obvious feature, LED street lamps are basically high color temperature, very few low color temperature products; do not pay attention to chip installation, sometimes LED street lights next to the traditional street lights. For example, on the main road of the city where the Dublin Spire is located, new street lights are built in the middle of the road using LED, and on both sides are the original traditional street lights.
As I understand it, in their eyes, resources are precious, traditional street lamps can be used, and if they break down, they will be replaced by more energy-efficient LED, but not necessarily one-time replacement in advance. This is a frugal and pragmatic approach, to the novel is a step-by-step thinking, to speak of the concept of urban growth. That is, the city's appearance is best to change gradually, not from time to time sudden change, even if the sudden change, but also to leave some historical buildings, sculptures, so that the public to remember, to know that collective memory is the best carrier of urban cohesion.
However, this practice will not work in China. What we emphasize is that it is too slow to change with each passing day, "one small change a year, one medium change three years, and one big change five years". It is better to develop by leaps and bounds, overtake at curves and emphasize one step in place. Looking back at the promotion of LED street lamps in the past few years in China, there is indeed room for improvement. Guangdong issued a promotional document at the end of 2012, requiring the Pearl River Delta to fully implement LED street lighting in 2013. The parties worked hard for a year to finish the task. If more than a few years, step-by-step, technology, product water to the canal, without forcing can be successfully completed.
Of course, there is a government demand for the development of LED industry behind the one-step approach, but layers of code, good intentions tend to go the other way. In this year's Guangzhou Lighting Exhibition, the same booth LED street lights are often two, the better is the export version, almost the domestic version. It is not entirely to blame the differences inside and outside the enterprise, LED technology is still in rapid development, hard to get in place, the enterprise can only cope with things. This kind of bad mentality, practices habitually, slowly became a path dependence, so the use of good things is sometimes our own.
In recent years, new technologies of lighting have emerged one after another. With the concepts of Smart City and 5G Communications, many lighting technologies and products are on the rise. It seems that overtaking Britain and the United States is just around the corner. Since there is a chance to overtake at a bend, it is a good time for you, small and medium-sized cities to be patient and step-by-step. This is a good time for you to snatch, clamp and hold the position.
Objectively speaking, gradual and step-by-step urban development is an integral two-sided, it is difficult to simply judge the advantages and disadvantages. However, for some of the rapidly developing technologies and products, many problems remain unsettled, the real demand is still changing, one-step trial and error costs are high. If the latter cannot be corrected, it will lead to a more difficult situation.
In fact, the development of some domestic cities has been quite basic, many lighting technology, products compared with international advanced cities are not inferior, the real gap is in the concept, concept. Since London is calling for a bid every day, it is better to meditate on other people's step-by-step approach and cultivate the concept of urban growth than to learn something superficial. Isn't gradual progress a counter-innovation in the frenzy of bending and Overtaking around the city?
