In order to meet the environmental protection requirements of energy saving and carbon reduction, countries have begun to actively enact legislation to ban incandescent lamps and fully switch to more environmentally friendly lighting solutions. In addition to the choice of CCFL fluorescent tube-type energy-saving lamps, the application of LED solid-state light source lighting energy-saving benefits Relatively high, and to make solid-state lighting energy-saving performance to a higher level, it must be combined with intelligent lighting system solutions according to a recent report from the United States Department of Energy (DoE) (DOESolid-StateLightingResearch and Development Multi-YearProgramPlan), 2010 National lighting power has accounted for total electricity consumption. 18. The report mentions that by introducing solid-state lighting (SSL) technology in 2025, it can save up to 217 TWh (Terawatt-hours) per year, saving The electricity that comes down is equivalent to one-third of the current electricity consumption in the United States! If you try to calculate the price of electricity at $0.10, it will save an annual savings of $217 billion, which is equivalent to the annual lighting price of 20 million American households.
Actively introducing LED energy-saving lighting can achieve significant energy-saving effects. DoE's report estimates are based on the full use of high-performance solid-state lighting technology to replace the traditional lighting source under the assumptions of the trial, regardless of whether the report is overly optimistic Estimate, but in fact it also highlights that with the advancement of technology, solid-state lighting technology can effectively reduce energy waste for lighting, thereby improving energy security, while also reducing greenhouse gas emissions indirectly or directly.
On the other hand, the solid-state light source needs to achieve 200 lumens/watt lighting efficiency, and the market penetration of LED lamps needs to reach 60 or more, so that the DoE can save up to 217 TWh of optimistic evaluation results for annual lighting power consumption.
According to the DoE report, solid-state lighting sources have improved significantly in 2013. Take the US market as an example. In 2013, the sales volume of solid-state lighting products was more than doubled in 2012, reaching 100 million. At the same time, the energy consumption saved by using solid-state lighting in 2013 was more than doubled in 2012. About $1.8 billion in electricity bills are saved, and $1.8 billion in electricity bills can pay for 14 million households in the United States.
At the same time, LED solid-state lighting fixtures in the market have achieved 200 lumens/watt performance in laboratory tests. On the other hand, OLED lighting applications have achieved 60 lumens/watt performance, and some manufacturers have developed OLED light source products with a lifetime of 55,000 hours. At present, the largest solid-state lighting products in the United States are still dominated by LED bulbs.
LED energy-saving benefits with intelligent control, such as Tiger's current LED bulbs in the replacement market, has become the first choice to replace high-energy incandescent lamps, but in fact, the light bulb principle of light changes, although it can save high power consumption, but in fact If you can combine lighting control with lighting applications, you can further use intelligent lighting to improve unnecessary energy consumption, so that the energy saving benefits are more significant.
In the latest intelligent lighting trend, in addition to the introduction of high-performance, new process energy-saving LED solid-state light source products in the luminaire, the most interesting thing is to combine the illuminating light and the interconnected LED lighting system with the integrated Internet remote control mechanism. Smart connection with space and lighting through the network, improving the traditional lamps, although using energy-saving light sources, but if the use of intelligent systems is not improved to reduce unnecessary waste, it can improve the efficiency of power saving.
Taking Philips' CityTouch intelligent lighting system as an example, under the concept of CityTouch intelligent lighting system, the city's outdoor lighting solid-state LED street lights can be remotely controlled in the remote central control room through the integrated wireless network solution of each street lamp. Closed, even the Bigdata technology can accurately check the current consumption of public lighting, making the regional energy consumption of public lighting more transparent, analyzable and computational.
Public lighting applications can be introduced into intelligent control platforms to enhance energy efficiency and traditional urban public lighting. In smart applications, most of them use only simple timing switch to automatically turn off street lights during daytime without lighting assistance, and through long-term sunshine season. The observation statistics need to open the opening and closing time of the equipment for public lighting, and then save energy efficiency by setting and maintaining the time switch.
However, in fact, the traditional power-saving timed on-off device scheme can save unnecessary lighting power consumption during the sunshine period, but actually encounters seasonal changes and bad weather conditions, and the control flexibility is lost by using a simple timer to open and close the lighting equipment. It is impossible to set the street light equipment opening and closing according to the actual sunshine situation, and when the control line is disconnected, it is necessary to send the commissioner to perform on-site maintenance, which is time-consuming and inefficient.
In the same application environment, the CityTouch intelligent lighting system can control the device through RF monitoring through remote monitoring. In the graphical operation interface, you only need to use the mouse to circle the regional public lighting, then select to turn off or on, you can remotely Manually control the running status of the equipment; in addition to the full support of the group lighting, the remote network can be turned on or off, the controller can also choose to open and close the outdoor lighting equipment without dispatching on-site processing. Philips claims that it can save 70% of energy consumption for urban lighting through the CityTouch intelligent lighting system.
The machine is often used in small building foundation, various backfill construction, earth foundation compaction. Suitable for materials with low adhesion and friction between rammed particles, especially for non-viscous sand. The compaction effect of crushed stone is remarkable.
Forwarder and reversible plate compactor with centrifugal force of 20-50 KN can cope with extreme demands as the reverse action allows better manoeuvrability in small spaces.
