    • Luminous Flux
    • Luminous Intensity
    • Illuminance
    • Luminance
  • 18. SOURCE: IESNA LIGHTING GUIDE history importance definitions criteria Dialux 4.6
    • LIGHT
    • The part of the electromagnetic spectrum that can be perceived by the eye.
    • - region of visible light extends from 380 to 760 nanometers
  • 19. SOURCE: IESNA LIGHTING GUIDE history importance definitions criteria Dialux 4.6 PHOTOPIC VISION Daytime adaptation which enable us to see in detailed color. (Eye peak at 555 nanometers) SCOTOPIC VISION At even lower illumination, giving completely black and white vision. Nighttime adaptation. (About 400 nanometers) MESOPIC VISION The overall appearance is less colorful under lower illumination level, like those of streetlighting or moonlight. (505 nanometers)
  • 20. SOURCE: IESNA LIGHTING GUIDE history importance definitions criteria Dialux 4.6
    • LUMINOUS FLUX
    • Quantity of Light emiited by a light source
    • Unit is in lumen, LM
    • LUMINOUS EFFICACY
    • measure of a lamps economics efficency
    • Ratio of the luminous flux to the electrical power consumed
    • - Unit is in lm/W
  • 21. SOURCE: IESNA LIGHTING GUIDE history importance definitions criteria Dialux 4.6
    • LUMINOUS INTENSITY
    • Quantity of light radiated to particular direction, radiated per unit of solid angle (steradian)
    • Unit is in candela, cd
  • 22. SOURCE: IESNA LIGHTING GUIDE history importance definitions criteria Dialux 4.6
    • ILLUMINANCE (E)
    • Quantity of luminous flux falling on a unit are of surface
      • E = F / A , unit is lux
    • INVERSE SQUARE LAW
    • Lux decreases by the square of its distance
      • Ep = I / d 2
    • COSINE LAW
    • Illuminance not perpendicular to source
      • Ep = I / d 2 cos Ø

    • ILLUMINANCE (E)
    • Quantity of luminous flux falling on a unit are of surface
      • E = F / A , unit is lux
    Summer noon, under a cloudless sky 100 000 lux Ditto, but in the shade 10 000 lux In the open under a heavily-overcast sky 5000 lux Artificial light, in a well-lit office 1000 lux Artificial light, average living-room 100lux Street lighting 5-30 lux Full moon, on a clear night 0,25 lux
  • 24. history importance definitions criteria Dialux 4.6 Calculation by Lumen Method: The average illuminance produced by a lighting installation or the number of luminaires required to achieve a specific average illuminance, can be calculated by means of utilization factors. The average illuminance E s over a reference surface s can be calculated from the “lumen method” formula. F x n x N x MF x UF s E s = ------------------------------ area of surface s where: F is the initial bare lamp flux (lumens, lm) n is the number of lamps per luminaire N is the number of luminaires Uf s is the utilization factor for the reference surface s MF is the maintenance factor (dirty: 0.7, normal: 0.8, clean: 0.9)
        • CRITERIA IN MANUAL CALCULATION
  • 25. history importance definitions criteria Dialux 4.6 Sample Problem: Mr. Cruz wants to light up his new warehouse in Laguna. The warehouse measures 20m x 30m. He wants to mount his luminaires on the trusses 8m above finish floor line. What type of luminaire will he use and how many of those will he purchase? Given: L = 20m, W= 30m, H = 8m, MF = use 0.8 Reflectances (use default) : C = 0.7 W = 0.5 F = 0.2 Solution: To obtain UF, solve for Room Index (RI) = A/(L+W)Hw, RI = 1.5 Required Average Illuminance (Eave) for warehouse as per standard is 100 lux

        • CRITERIA IN MANUAL CALCULATION
  • 27. history importance definitions criteria Dialux 4.6 Solution (cont.): Since mounting height is 8m, use high bay fixture. From UF table of Thorn High Bay, UF = 0.78 Substituting to equation: F x n x N x MF x UFs E = ------------------------------ A (100)(600) N = ------------------------------- (27500)(1)(0.8)(0.78) N = 3.49, use 4 sets 250W SON-T high bay lighting fixture Checking the lighting level, E = 114.4 lux

        • DIALUX 4.6
    • HISTORY
    • - a software project launched by Dial GmbH
    • - It started in 1994 in Dial, Ludenscheid, Germany
    • - lighting design tool which is continually updated and adapted to the requirements of the planners
  • 29. history importance definitions criteria Dialux 4.6 WHY SHOULD I USE IT? ~ A complete software package FREE OF CHARGE with photo realistic visualization. ~ Available in all main languages of the world (26 languages at present) ~ Import and export to and from all CAD programmes in .dxf and .dwg format ~ Import and use 3ds file format for more realistic models ~ Creation of films for the presentation of photo realistic visualization ~ DIALux is independent and manufacturer-neutral. ~ Incorporates the latest norms and standards as well as the accepted approaches in any respective country ~ Functional in most common Operating Systems ~ Also available, Dialux Light, for quick indoor calculation ~ Ready customizable Indoor, Road, Area and Sports lighting calculation ~ Available wizard for easy calculations
