The development of China's economy is heating up, and the development of the city has also driven the rapid development of road construction. By the end of 2007, the total mileage of highways in China has reached 3.573 million kilometers. At the same time, the number of street lamps in China has reached 10 million, and it is growing at a rate of 20% per year. If it is calculated by a 250W sodium lamp, it will cost 10 billion kWh per year.
These huge data show that the energy-saving work of urban road lighting in China is not only urgent but also promising.
Nowadays, a number of innovative and technological products, such as high-efficiency and energy-saving high-pressure sodium lamps, have provided strong support for improving the current situation of road lighting in China and promoting road lighting energy conservation. For example, Philips, the global leader in lighting, has brought high-efficiency high-pressure sodium lamps SON-T PIA plus, a high-end energy-saving product in high-pressure sodium lamps, which is another major innovation in the field of road lighting.
Efficient and durable lighting to promote road energy saving
The huge road lighting costs are composed of energy costs, maintenance costs, product procurement costs, and power distribution installations. In the current situation of China's power and energy shortage, if we can improve the lighting quality while improving the lighting efficiency and reduce the use and maintenance costs, it will be a great contribution to road energy conservation. Philips high-efficiency high-pressure sodium lighting can be as high as 145lm / W, up to 20% than ordinary high-pressure sodium lamps. Its average service life can be as long as 32,000 hours, which is 33% higher than the traditional high-pressure sodium lamp with a lifetime of only 24,000 hours, and the maintenance cost is reduced by about 30%.
First-class technology often determines superior product performance. The Philips high-efficiency high-pressure sodium lamp uses Philips' proprietary PIA patented integrated antenna liner and a polycrystalline alumina ceramic tube imported from the Netherlands. These unique advanced technologies completely eliminate the early failures that can occur in older products and significantly increase lamp life. In addition, it also makes it easier to start, and the time to start again is faster.
Extensive practical application shows broad prospects
Today, road lighting has played a more comprehensive and more energy-efficient prelude to the whole. Philips high-efficiency high-pressure sodium lamp provides a powerful driving force for road lighting energy saving in the practical application of roads nationwide.
The Xi'an Third Ring Road System Project, which started construction in 2003, will be open to traffic throughout the year. The completion of the project will be of great significance for effectively alleviating traffic pressure and improving the status of the road network in the suburbs of Xi'an. In this important project, the street lamp management office used 1,320 sets of Philips high-efficiency high-pressure sodium lamp SGP268/250W SON-T according to the road conditions, surrounding environment, traffic flow and passenger flow requirements. After installation, the brightness of the road is completely up to standard, the uniformity is good, and the use and maintenance costs are greatly saved. The direct experience and beneficiaries of streetlights - drivers and passers-by - reflect that bright street lights make them more reassuring at night.
In addition, in the third ring road of Daqing, Chengyang Road in Qingdao, Jinshui East Road and Zidong Road in Zhengzhou, Jiaxing Road in Shanghai, and 227 National Road in Suzhou and Dongyan in the South Ring Road in Suzhou, the high-efficiency high-pressure sodium lamp is highly efficient and long-lived. The advantages significantly reduce the overall cost of road lighting, and have been adopted and recognized by street lamp owners. Whether it is a fast road or a main road, it will usher in a broader future.

Type-C interface has strong expansion ability, can transmit video and video signals, expand to a variety of audio and video output interface, such as HDMI, VGA, DVI interface, and even achieve 4K resolution of the extended transmission. The Type-c interface provides bidirectional power supply, which can charge the device itself or power external devices.USB HUBS has better data transmission capability and higher charging power. USBType-C went into mass production in August 2014, using the 3.1 standard. Compared with the interface of USB2.0 used in early smartphones, the transmission speed is improved a lot, and the maximum data transmission speed can reach 10Gbit/ s. And type-c supports USB-PD power supply standard, the maximum power supply can be up to 100 watts. Different from the traditional USBType-A and Type-B interfaces, the new Type-C interface is slimmed down in size to 8.3*2.5mm, which is more suitable for use in increasingly miniaturized electronic devices.
Supports positive and negative insertion. 100% of the players who use USB interface have encountered the embarrassment of "the positive plug is wrong, the negative plug is wrong, and the positive plug is right". Because USB-C IS POSITIVE AND NEGATIVE CAN be inserted, professional point is to say that the interface does not have directionality, with much more convenient. type-c charging port, support PD fast charging protocol, can be charged while using the computer, not afraid of running out of power. HDMI interface, I like HDMI to support audio and video transmission, high resolution support 4K/2K. Interface is common, LCD TV, monitor, projector are generally also some (like to connect to TV, audio and video synchronous transmission).vga interface, this is a very common interface, most of the projector, monitor have this interface, can be connected to vga line use, support 1080P resolution. Gigabit network port, although now almost everywhere there is a wireless network, but sometimes it is not enough for you, such as playing games, the network speed is slow, delay. And then he dropped the line right in the middle of his victory. So if you have a network cable and you can connect directly to the Internet, it's great to support gigabit networks.
