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.

Full Spectrum Led Grow Light For Greenhouse/Hydroponics/Plants Growing
What is Full spectrum led chip ?
It is the newest trend for LED Horticulture Lighting. Advanced Led Grow Lights chip, not provide sigle color,provide broad spectrum 400nm~840nm ,simialr with sun light ,but most is red and blue ,it is best for LED Horticulture Grow Lights.This is a revolutionary step for LED Grow Lights which have previously been unable to act as the sole light source for the indoor garden.Suitable for all stages of plant growth.
How to Select the Best Grow Light for your Greenhouse?
The plant needs light to thrive cause the light is essental for photosynthesis.without it,plants can not make food.but light can also be too intense,too hot or last too long for growing healthy plants.plant growth accelerates with abundant light because more of the plant`s leaves have exposure,which means more photosynthesis.in the winter,days are not long enough,but many plants still need 12 hours or more of light per day.now,adding led grow lights to your greenhouse is an nice choice if you live in the north, and can not get enough daylight in winter.you might be take HID into consideration,cause it has high output and cover a wide area.but now,we providing you some dfferent.the newest type of grow lights use LED technology.
Provides Maximum Light Density and optimizing spectrum(410nm-740nm,white)
As we know that the plants need more light from the blue side of the spectrum during their seedling stage and when developing foliage and require light from the orange to red side of the spectrum while inblooming and fruiting phases. We adopting lastest intergrated COB technology, white , more red and blue PAR(410-740nm) per Watt than any other lighting fixture for the best color uniformity.
Dual Veg and Bloom for plant growth and bloom
The Led grow lights feature selectable VEG and BLOOM light spectrums to deliver maximum performance from seeding through the flower stage and finally harvest.
Increase yields and potency
Using high quality lense that hyper-focus the lights on your canopy.the photons are beamed directly to the plants.this gives growers the ability to get greatest possible crop yield.
Reduce your costs with energy efficiency
Energy-efficient cannabis grow lights cost between 40%-60% less to operate compared to HID lam year
Led Grow Light also eliminate the needs for ballasts and reflectors while they minimize the cooling systems,accelerating your payback.you will see the electrical bills trimmed by approximately half,year after year.
Installs and operates simply
the input voltage is AC100V-240V,fit for the world standard,built-in power supply.do not need other equipment,just access to the Plug,the lamp will be work smoothly. The Led Grow Lighting is small size,just few inches and easy to install.it is the good option for some greenhouse.
Long lifespan
Using built-in quiet fans and the shutter in the wind,induced draftfrom all sides.runs with quiet. Useadvanced isolation power supply and soft start protection technology, to prevent the high voltage when turn on the light from damagingthe lamp body.
