The LED brightness metering
The same with traditional light sources, LED light source of optical measurement units are uniform. In order for you the reader to understand and easy to use, the following introduce the relevant knowledge briefly:
1、luminous flux
Luminous flux refers to the light source in the unit of time given the amount of light, that radiated power can be felt by the human eye that part of radiation energy. It is equal to unit time of a band of radiation energy and the band see the rate of relative depending on the product. As the human eye to different wavelengths of light, see different rates depending on the relative, so that different wavelengths of light radiated power are equal, not equal luminous flux. The symbol for luminous flux Φ, unit lumen (Lm).
The basis of spectral radiant flux Φ (λ), so can be derived flux formula:
Φ=Km Φ（λ）gV（λ）dλ
In the formula, V (λ) - relative spectral luminous efficiency; Km-radiation spectrum of light depending on the performance of the maximum, the unit for Lm / W. Measured in 1977 by the International Committee to determine Km values 683Lm / W (λm = 555nm).
2、Luminous intensity
Luminous intensity is defined as per unit area per unit time through the light energy, energy and frequency proportional to the intensity of their sum (ie integral) can also be understood as the light source in a given direction, the luminous intensity I is the light source solid angle in the direction of the luminous flux dΦ yuan in transfer divided by the solid angle element dΩ of the business
The unit of luminous intensity is the candela (cd), 1cd = 1Lm/1sr. Space in all directions, and is the flux of light intensity.
3、light brightness
We are in testing and evaluation of brightness LED chips LED light radiation safety of the process, commonly used imaging method can be used for the test chip micro-imaging to measure. Brightness is the source of a light-emitting surface brightness at L, is the surface element dS in a given direction of the luminous intensity divided by the surface element in a given direction perpendicular to the plane of orthographic projection area of the business
Brightness of the unit is the candela per square meter (cd/m2). When the light is perpendicular to the surface and measurements, then cosθ = 1.
4、Light illumination
Light Illumination refers to the object is illuminated the extent received by use of luminous flux per unit area expressed. Illuminance and light source, the illuminated surface and the location of light in space, size, and light sources and light intensity is proportional to the angle of Yu Xuan, but with the light source to the illuminated surface is inversely proportional to the square of the distance. A point on the surface of the illumination E is the incident surface elements that contains the point on the luminous flux dΦ divided by the surface area dS of the yuan business.
The unit of Lux (LX), 1LX = 1Lm/m2.

LRC issues report on LED lighting for airfields 25 Jul 2012 The Lighting Research Center at Rensselaer Polytechnic Institute has published a report to help guide airports as they consider LED lighting for various needs around an airfield. The new report, "Issues with use of LED airfield lighting: ACRP synthesis 35," published by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, concludes that reduced maintenance cost is the primary benefit for airports considering a move to LED lighting in the airfield. Energy savings are secondary in part because airfield electrical systems are designed for incandescent loads. The Transportation Research Board (TRB) of the National Academies published the LRC-authored report in conjunction with the Airport Cooperative Research Program (ACRP) which funded the study. The LRC has also long worked with the Federal Aviation Administration (FAA) on ways to take advantage of solid-state lighting (SSL) technology on airfields. John Bullough, senior research scientist and adjunct professor at the LRC, authored the report. "LED airfield lighting uses much less energy than incandescent, but airfield electrical systems are optimized for incandescent lamps, not LEDs," said Bullough. "Even more energy can be saved if electrical systems are designed with the reduced loads of LEDs in mind." Other findings of the report include the fact that the visibility and performance of LED lighting on airfields is generally good. Early on in the development of LED lighting there were what the report called "compatibility problems" with SSL and airfields but those have been overcome. The research was based on detailed surveys of 22 airports and aviation agencies. The report speculates that despite high upfront costs, the installation of LEDs will generally payback in "several years." An upgrade of the electrical infrastructure can increase energy efficiency and reliability of airfield lighting systems. According to the LRC, the FAA is now investigating new infrastructures for airfield lighting. Previous We have TUV Certificate of LED Tube Next Cree focuses on the system-level approach to SSL, while Bridgelux discusses the cost roadblock, and Nichia touts market presence and LED and phosphor experience.

LED Vs Fluorescent Lighting
LED lighting and fluorescent lighting are just two of the types of lighting technologies available. Both have their own sets of advantages and disadvantages. One key area that they differ in is the area of energy consumption and lifespan. Comparing LED lighting and fluorescent lighting requires taking a look at a few key specifications.
Types
LED lights are light emitting diodes and are found either as single diodes, such as in a flashlight, or as a cluster of diodes to create a light bulb. Fluorescent lighting comes in two primary types: tube lighting and CFL (compact fluorescent lighting). Fluorescent lights can range in size from tubes multiple feet long to the compact bulbs that are about the size of a standard lamp light bulb.
Lifespan
LED lighting can last upwards of 60,000 hours before needing to be replaced. Fluorescent lighting, particularly CFL bulbs, can last around 10,000 hours before needing to be replaced. You would have to replace the average CFL bulb 6 times to equal the lifespan of one LED tube.
Lighting Ability
LED lighting is ideal for directional lighting. Directional lighting is useful in lights such as flashlights and desk lamps. The light focuses on where the bulb is pointed rather than bathing the wider area in light. LEDs are also found in vehicle headlights and electronic devices for status lights.
Fluorescent light bulbs are ideal for lighting up full rooms, with full-size tubes being ideal for large rooms such as warehouses where focused light is not needed. CFL bulbs are useful for home use and lighting up bedrooms and living areas.
Energy Consumption
LED light bulbs use about half the wattage of fluorescent lighting, about 6 watts of power versus 14 watts of power for a CFL light bulb. For an LED bulb's lifespan, about 340 kilowatt hours of electricity is used. CFL bulbs used over 60,000 hours (6 bulbs) will use around 840 kilowatt hours of electricity, according to the website Product Dose which compared different light bulb energy specifications.
