50% of Chengdu's two tunnel pilots use energy-saving lamps to reduce electricity costs by 50%
Mr. Zhang, who often drives through the Red Star Road Tunnel, has been wondering: the light color of the two tunnels is white on one side and yellow on the other. Why is this? The person in charge of the Chengdu Drainage Facility told the author that the tunnel has been in operation since last year. The comparison test of lighting energy-saving retrofit shows that the white light from the top of the tunnel to the north is energy-saving lamps, and the energy saving rate can reach 50%. The person in charge revealed that the next 19 urban suburban tunnels and the Third Ring Road are expected to promote such energy-saving lamps.
Two tunnels can save up to 50%
In addition to the Hongxing Road Tunnel, the water-milling tunnel under the tunnel from the south to the north was also transformed with energy-saving lamps at the end of January last year. Jinjiang District Power Supply Bureau electricity fee collection details show that in January last year, the tunnel electricity expenditure was 11,513 yuan, February 11,524 yuan, March steeply dropped to 6,259 yuan, April 8004 yuan. The "User Trial" of the Municipal Drainage Facilities Department also shows that the energy saving rate of such lamps is 50%.
The person in charge of the renovation of the tunnel lighting, the scientific name of this energy-saving lamp is called high-frequency electrodeless fluorescent lamp, 100 watts per urn. The same number of luminaires provide better lighting conditions than the 250 watt high pressure sodium lamps currently in use. Moreover, the service life of high-pressure sodium lamps is only one year, which is about 5 years less than the life of energy-saving lamps. Calculated by the data of Hongxing Road and Shuirun River under the tunnel: If the tunnel under the 19th city is completely renovated, it can save more than 2 million kWh per year and save more than 1.6 million yuan in electricity.
How does Chengdu citizen feel when changing to energy-saving lamps? Master Liu is a driver of a company near Hongxing Road. He thinks that the weather is generally two roads, but if the outside light is strong and the sun is shining, the advantage of energy-saving lamps is more obvious because white The light is closer to the natural light, and when you first enter, there is no feeling that the eyes are not suitable at all.
19 under the tunnel and the third ring is expected to promote
However, the initial investment in the renovation of lamps is not a small expense. Taking the above two tunnels as an example, together with the lamps and the complete installation services, a total investment of more than 500,000 yuan. To this end, the transformation enterprise proposes to adopt the contract energy management operation mode (EMC), which provides products and services by the company, and all expenses are paid annually from the saved electricity costs.
It is understood that a request report submitted by the Chengdu Economic Commission to the municipal government at the beginning of the year proposed that if all 19 municipal tunnels use high-frequency electrodeless fluorescent lamps, the electricity cost saved in two years can recover the full cost of the investment. The report also recommended that the municipal government first pilot the tunnel and the third ring road in the 19th city, and strive to promote the application in three years.
The person in charge of the Chengdu Drainage Facilities Department said that in the next step, the tunnel will be under the tunnel and the other half of the tunnel under the water mill, and the Dongcheng root tunnel will be used to promote the pilot energy-saving lamps.
MTR wants to promote the full use of LED lighting systems
LED light pipes with high energy efficiency are getting more and more popular. In addition to the increasing popularity of LED TVs, Hong Kong MTR Corporation started this week and used LED lighting systems in a train on the Tsuen Wan Line. The LED lighting system saves 30% energy compared to conventional light pipes, and its life expectancy is three times longer than that of ordinary light pipes. The MTR said that the new lighting system not only saves energy, but also achieves environmental protection purposes. It will depend on passenger response and consider promoting it to the whole line.
It is understood that the MTR Corporation spent 4 million yuan to install environmentally friendly lighting fixtures on three MTR trains, using high-brightness LEDs. The three MTR trains will be equipped with lighting fixtures consisting of 64 high-brightness LED chips. One of the trains will be put into service on the Tsuen Wan Line this week, and the remaining two will be commissioned by June 2009. The MTR will also test the new lighting system at the Rainbow Station for daily lighting purposes. The project is expected to be completed by August. At present, there are more than 100 trains on the MTR. The MTR will test the new lighting system for two years. It will consider whether the passengers will respond and the technical feasibility. Chen Zhenghao, a professor of electronics and calculator engineering at the Hong Kong University of Science and Technology, who is responsible for researching the new system, said that the newly improved high-brightness LEDs are expected to use only 70% of the traditional light pipes, saving 30% of energy and lasting up to 50,000. Hours, 3 times more durable than ordinary light pipes. In addition, when a high-brightness LED chip fails, it is only necessary to replace the chip to reduce waste and achieve environmental benefits.
Fuzhou main road traffic lights with bright LED lights
All traffic lights on the main road in Fuzhou will be updated to LED lights with a diameter of 400 mm. On February 14, the author also learned from the city's traffic patrol detachment another good news. In the future, new, expanded and rebuilt roads will ensure that road construction and transportation facilities are in place, and relevant traffic lights and marking lines are also synchronized with road construction. The road has been repaired and can be used immediately.
According to reports, at present, the traffic lights of the main roads in Fuzhou City have basically realized LEDization. Now, some of the original diameters of only 300 mm are being expanded to reach 400 mm.
The characteristics of LED traffic lights are: energy saving, long service life, brighter and more conspicuous. In addition, there is a very important feature that LEDs are not like ordinary incandescent lamps. Even if one of the bulbs is broken, it will still have little effect on the whole lamp body. Only a small black spot appears in the center of the lamp, but it is only a partial black spot. Does not affect the use of the entire traffic light.
At present, in terms of road construction, the Municipal Traffic Patrol Detachment and the Municipal Construction Bureau implement a four-synchronization mechanism, which integrates road traffic safety facilities into road construction projects, and simultaneously designs and constructs the main roads of new construction, expansion and reconstruction according to national standards. At the same time, acceptance and simultaneous use.

HDI PCB refers to high-density interconnect Printed Circuit Boards. HDI Board is a key part of the PCB and electronics industries increasingly. Electronic components become smaller and lighter, however still require ever-improving performance. To adapt this situation, people have to pack more functionality into a smaller area.
Many functions are improved by HDI Printed Circuit Board, such as denser trace routing is denser, power is more stable, interference inductance and capacitance effects is reduced, signal integrity in high-speed design is improved.
That`s just HDI PCB can do!
Other advantages
- Size and weight of products can be reduced.
- Electrical performance is improved.
- Cost-effectiveness is increased.
- Production time is faster.
Applications
- Consumer Electronics, such as laptops, smartphones, tablets, and wearable, as well as other consumer electronics like digital cameras and GPS devices, smart thermostats, fridges and the many other connected devices available.
- Communications: such as routers, switches, modules, and semiconductors. Digital video and audio equipment, etc.
- Automotive and Aerospace: Cars are becoming more connected and computerized. About 50 microprocessors on board that play a role in engine controls, diagnostics, safety features and other conveniences for cars today. Also on board Wi-Fi and GPS, rearview cameras and backup sensors rely on HDI PCB.
- Medical devices, for example, imaging, monitoring, surgical procedures, laboratory analysis, and others.
- Industrial equipment.
