LED street light white city?

White light near the sun, better lighting

Chancheng District Bureau of public utilities project relevant responsible person explained: the white light LED lamp for Different people, different views. feeling, each person's preferences and feel different.

At the beginning of the use of fluorescent tubes, a lot of people are not accustomed to the use of white light, but now basically no one will oppose. The so-called terrorist is caused by people's compulsive habits, and now the light is more close to the sun, and also enjoy the sun during the day is a progressive choice. "

In addition, the yellow light LED lamp can be achieved, but the luminous efficiency will be significantly reduced, about 80% of white light. In fact, the original yellow light is determined by the principle of high pressure sodium lamp light, if the initial issue is white, yellow light today will be controversial. "

LED street lamp is too expensive, large-scale replacement caused financial waste?

Longer service life, 5 years free warranty

It is understood that, with the development of the industry, the scale effect and market supply and demand ratio changes, the cost of LED street lamp has been reduced from the initial 8000 - 9000 yuan to about $4000. Chancheng replaced the price of LED street lamps are around 4000 yuan. According to the current LED production costs, the price is close to the cost price.

The person in charge, the price of lamps can not simply add or subtract. LED lamp life of up to 50 thousand hours, while the metal halide lamp life in the 6000 - 12000 hours. If in 1 years as a unit of calculation, the cost is certainly increased. However, in 5 years, electricity, lamps and other far lower than the current use of street lamps, so in the long run, the cost is reduced. And in 5 years, the high-pressure sodium lamps need to be replaced by 2 - 4 times, not routine maintenance, but the cost of each replacement is very high.

With the application of the model, the government shall not be invested or a small amount of funds, will be the introduction of new LED technology and products, to avoid their own separate bear many risks in technology financial and other aspects of the project is likely to encounter.

After the replacement lighting effect is not improved or even decreased?
