LED is more than 80% more energy efficient than traditional light bulbs. It is known as the energy-saving emerging industry in the 21st century. The Ministry of Economic Affairs and the Energy Bureau spent 300 million yuan two years ago to incorporate LED signs into major public construction. I hope that by 2010, Became the first country in the world to take full advantage of LED traffic signs.
The public? Purchasing low-cost quality, good quality, and incompleteness are good, but it also causes many problems. Officials from the North County Transportation Bureau said that the public sector purchase price is low, and the traffic signal LED durability is worrying. It is not surprising that only half or one-third of the traffic signs are bright.
Zhu Jianquan, head of the Traffic Control Engineering Department of the North County Transportation Bureau, pointed out that each traffic number consists of about 90 to 110 tiny particles of LEDs, which are like insects. They are subject to changes in the specifications of different manufacturers. Technology, heat dissipation problems, LEDs are prone to "bad spots", affecting the function of the number.
Zhu Jianquan said that although the manufacturer provides two years of warranty, there is no specific replacement standard. For example, the six bad points of the computer screen can be replaced free of charge, but the LED traffic sign has no guidelines. Everyone can only look at the image and stand on the traffic sign. Under the visual inspection, if it is calculated that more than one particle is broken, the manufacturer's warranty update will be negotiated.
There are many "bad spots" in the vicinity of the county people's avenue in Beixian County and the double-drain road in Sanlu District, and even in the Beitou District and Shilin District of the North City (see above, photo by Lin Jinchi), not only looks awkward It also affects the driver's discernment; the driver laughs and says, it is simply "red, green, stupid."
The warranty standard does not affect traffic safety Zhu Jianquan said that the central government has not stipulated uniform warranty standards, and the counties and cities have not followed the standards and can only be regularly inspected and replaced.
Guo Zongsheng, director of the Traffic Control Engineering Department of Taipei City, said that the city began to test traffic signs in the 1990s. LED lights, including traffic signs, variable signs, auxiliary signs, etc., were replaced at the beginning of last year at more than 2,000 intersections. The LED traffic sign is made up of many small light bulbs. To ensure that the people clearly recognize the number, at least 80% of the light bulbs must be on.
Guo Zongsheng said that the longer the lamp is used, the lower the brightness. Basically, the lamp life is 100,000 hours. The actual use is about six years. The north city has about one or two bulbs per month that do not meet the regulations, accounting for the total number of bulbs. Five to â—‹? Seven percent, if the light bulb does not light, immediately send someone to repair to ensure traffic safety. 
The government is preparing to change the traffic number to LED lights (light-emitting diodes). The problem is that the LED traffic signs of the public sector are currently in good condition, resulting in uneven quality of the particles, resulting in only half or one-third of the roadside visible. Traffic lights, almost to the "red, green, silly points are not clear 9, the durability is worrying, not only unsightly, but also affect traffic safety.
