Installation problem
summary
Both the questionnaire report (Appendix B) and the published literature point out that there are some important issues to consider when planning an airport to install LED airport lighting:
• Installing LED airport lights seems to be more difficult to install than incandescent lamps.
• There will be compatibility issues between LED airport luminaires and existing power infrastructure designed to operate incandescent lamps. It is important to verify with the manufacturer before installation to verify that the LED system is compatible with existing adjustment and control equipment.
• It is also important to work closely with LED luminaire manufacturers during the installation process to help them troubleshoot and potentially unknown problems. Pittman (2010) reports that at Durham International Airport (North Carolina), manufacturers are key members of the LED installation team and are often consultants throughout the installation process.
LED installation expectations
According to the survey participants, the main reason for installing LED airport lighting is to reduce maintenance costs (20 people say), reduce energy consumption (18 people), and improve airport lighting visibility (13 people). Interestingly, no one said it was due to any legislative directive. While national energy legislation, such as the EISA (Energy Independence and Security Act of 2007), has raised the light efficiency requirements for general-purpose luminaires, many existing incandescent lamps may not meet this requirement in the next decade, but the bill seems to It does not affect the decision of the airport to make lighting. One reason may be that the provisions in the Act do not include special light source types such as earthquake protection and some hazardous applications, such as airport lighting (NRDC 2011).
Reduce maintenance
The desire to reduce maintenance is also often mentioned in the literature. Copenhagen Airport noted that its recently installed LED obstacle lights are expected to last 100,000 hours, far longer than the 2,000-hour life of incandescent lamps (Stegmann 2010), and a five-year operating warranty from the manufacturer. The International Airports Association (2007) reported that LED slide lights at Vancouver Airport are expected to reduce maintenance costs compared to incandescent lamps; (News) LED stop line lights at Newcastle International Airport are expected to extend the maintenance cycle of this system from one month Extended to six years (Marsh et al. 2008); Burlington (Vermont) International Airport (Edelstein 2009), (New York City, Arkansas), News News Service 2009a, Trenton, New Jersey Airport (TendersInfo 2010a), San Bernardino (California) International Airport (TendersInfo 2010b), Raleigh-Dalham International Airport (News and Observer 2010), Tulsa (Oklahoma) International Airport ( Stewart 2011a), these airports have similar reports on LED slides and runway lights. ,
Reduce energy consumption
Reducing energy consumption is another important reason for installing LED lights to replace incandescent airport lighting systems. In the literature (Airpor ts Co unci l International 2007; Rainey 2007; Nowak 2011) can also find expectations to reduce LED airport lighting energy consumption. The US General Accounting Office (USGAO 2010) listed LED airport lighting as one of the four common energy-saving devices in the airport. At Newberg Airport, reducing energy consumption is one reason for installing LED taxiway lighting (States NewsService 2009a; Targeted News Service 2010), which is expected to consume only 25% to 33% of incandescent energy. Burlington International Airport (Edelstein 2009; States News Service 2009b), States News Service 2009c, and TendersInfo 2010a also hope to achieve energy savings through LED taxiway lighting. Part of the taxiway and runway at San Bernardino International Airport has been replaced with LED lights, as there are claims that the energy consumed by LED lights is only a fraction of the consumption of incandescent lamps (TendersInfo 2010b). Montreal-Pierre Elliott Trudeau International Airport expects its LED taxiway and runway lighting to consume only one-third of incandescent light, Canadian Corporate Newswire 2008a. Mid-line lighting at the Prince George Airport airport runway in British Columbia is also expected to use less energy than traditional luminaires.

TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.
It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.
TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.
The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
