  • Illumination and Distance
    PHYS 1400: Physical Science Laboratory Manual ILLUMINATION AND DISTANCE INTRODUCTION How bright is that light? You know, from experience, that a 100W light bulb is brighter than a 60W bulb. The wattage measures the energy used by the bulb, which depends on the bulb, not on where the person observing it is located. But you also know that how bright the light looks does depend on how far away it is. That 100W bulb is still emitting the same amount of energy every second, but if you are farther away from it, the energy is spread out over a greater area. You receive less energy, and perceive the light as less bright. But because the light energy is spread out over an area, it’s not a linear relationship. When you double the distance, the energy is spread out over four times as much area. If you triple the distance, the area is nine Twice the distance, ¼ as bright. Triple the distance? 11% as bright. times as great, meaning that you receive only 1/9 (or 11%) as much energy from the light source. To quantify the amount of light, we will use units called lux. The idea is simple: energy emitted per second (Watts), spread out over an area (square meters). However, a lux is not a W/m2! A lux is a lumen per m2. So, what is a lumen? Technically, it’s one candela emitted uniformly across a solid angle of 1 steradian. That’s not helping, is it? Examine the figure above. The source emits light (energy) in all directions simultaneously.

  • Tip Sheet – Lumen Meter
    TIP SHEET – LUMEN METER What is a lumen meter? A light meter or lumen meter is a device used to measure the amount of light in a certain area. Lumen meters have many uses such as photography and cinematography, however for our purpose we want to help reduce the amount of wasted light which equals wasted electricity. If conducting an outdoor lighting audit the purpose of a lumen meter would be to reduce the amount of light pollution. Light output is typically measured in luxes or lumens. Sometimes you will hear the word footcandles. This is another standard unit of measure that is used interchangeablely with the term lumen. Ehow.com defines a lux as a uniform standard by which the amount of visible light present in a given space can be described where as a lumen is a measure of just how much visible light is produced by an object such as, for example, a light bulb. 1 footcandle/lumens = 10.76 luxes and 1 lux =.093 footcandles or lumens Where can I purchase a lumen meter? Eco-Schools USA recommends the light meter from Mastech found on Amazon.com. http://www.amazon.com/Mastech-Light-LX1010BS-display- Luxmeter/dp/B004KP8RE2/ref=sr_1_5?s=electronics&ie=UTF8&qid=1342571104&sr=1-5 Mastech Light Meter LX1010BS with LCD display, 100,000 Lux Luxmeter - $20.17 Operating directions Mastech Light Meter LX1010BS with LCD display, 100,000 Lux Luxmeter operating instructions are found on the next page. The unit of measure displays in luxes. This will be a great opportunity for your student to work on conversions.

    Recommended Light Levels Recommended Light Levels (Illuminance) for Outdoor and Indoor Venues This is an instructor resource with information to be provided to students as the instructor sees fit. Light Level or Illuminance, is the amount of light measured in a plane surface (or the total luminous flux incident on a surface, per unit area). The work plane is where the most important tasks in the room or space are performed. Measuring Units of Light Level - Illuminance Illuminance is measured in foot candles (ftcd, fc, fcd) or lux (in the metric SI system). A foot candle is actually one lumen of light density per square foot; one lux is one lumen per square meter. • 1 lux = 1 lumen / sq meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd) • 1 phot = 1 lumen / sq centimeter = 10000 lumens / sq meter = 10000 lux • 1 foot candle (ftcd, fcd) = 1 lumen / sq ft = 10.752 lux Common Light Levels Outdoors from Natural Sources Common light levels outdoor at day and night can be found in the table below: Illumination Condition (ftcd) (lux) Sunlight 10,000 107,527 Full Daylight 1,000 10,752 Overcast Day 100 1,075 Very Dark Day 10 107 Twilight 1 10.8 Deep Twilight .1 1.08 Full Moon .01 .108 Quarter Moon .001 .0108 Starlight .0001 .0011 Overcast Night .00001 .0001 Common Light Levels Outdoors from Manufactured Sources The nomenclature for most of the types of areas listed in the table below can be found in the City of Los Angeles, Department of Public Works, Bureau of Street Lighting’s “DESIGN STANDARDS AND GUIDELINES” at the URL address under References at the end of this document.

  • How to Define the Base Units of the Revised SI from Seven Constants with Fixed Numerical Values
    Rapport BIPM-2018/02 Bureau International des Poids et Mesures How to define the base units of the revised SI from seven constants with fixed numerical values Richard Davis *See Reference 7 February 2018 Version 3. Revised 6 April 2018 Abstract [added April 2018] As part of a revision to the SI expected to be approved later this year and to take effect in May 2019, the seven base units will be defined by giving fixed numerical values to seven “defining constants”. The report shows how the definitions of all seven base units can be derived efficiently from the defining constants, with the result appearing as a table. The table’s form makes evident a number of connections between the defining constants and the base units. Appendices show how the same methodology could have been used to define the same base units in the present SI, as well as the mathematics which underpins the methodology. How to define the base units of the revised SI from seven constants with fixed numerical values Richard Davis, International Bureau of Weights and Measures (BIPM) 1. Introduction Preparations for the upcoming revision of the International System of Units (SI) began in earnest with Resolution 1 of the 24th meeting of the General Conference on Weights and Measures (CGPM) in 2011 [1]. The 26th CGPM in November 2018 is expected to give final approval to a revision of the present SI [2] based on the guidance laid down in Ref. [1]. The SI will then become a system of units based on exact numerical values of seven defining constants, ΔνCs, c, h, e, k, NA and

Example of a typical radiometer 3 W. Wang Photometry All light measurement is considered radiometry with photometry being a special subset of radiometry weighted for a typical human eye response. Example of a typical photometer 4 W. Wang Human Eyes Figure shows a schematic illustration of the human eye (Encyclopedia Britannica, 1994). The inside of the eyeball is clad by the retina, which is the light-sensitive part of the eye. The illustration also shows the fovea, a cone-rich central region of the retina which affords the high acuteness of central vision. Figure also shows the cell structure of the retina including the light-sensitive rod cells and cone cells. Also shown are the ganglion cells and nerve fibers that transmit the visual information to the brain. Rod cells are more abundant and more light sensitive than cone cells. Rods are 5 sensitive over the entire visible spectrum. W. Wang There are three types of cone cells, namely cone cells sensitive in the red, green, and blue spectral range. The approximate spectral sensitivity functions of the rods and three types or cones are shown in the figure above 6 W.

Radiation, radioactivity and radioactive materials are outlined below. A light bulb, an object familiar to everyone, has the ability to emit light. Light bulb brightness is expressed in the unit of "Lumens" or "Watts." People receive the light and feel the brightness. The unit in this case is "Lux." The units related to radiation, such as becquerel and sievert, which we often hear about lately, also have a similar relation to the above. For example, when a rock emits radiation, this rock is called a "radioactive material" (p.3 of Vol. 1, "Units of Radiation and Radioactivity"). Radioactive materials emit radiation, and this ability is called "radioactivity." In this case, it is expressed as "This rock has radioactivity" or "This rock emits radiation." This ability of emitting radiation is expressed in the unit of "Becquerel (Bq)." "Sievert (Sv)" is used as the unit of the radiation exposure dose necessary to know the effect of radiation to which a person is exposed. There is a special conversion factor to calculate "Sv" from "Bq." Higher radioactivity (value expressed in becquerels) means that the relevant radioactive material emits more radiation, but radiation exposure dose (value expressed in sieverts) varies depending on the distance between the radioactive material and the person exposed thereto.
