Ellipz Lighting Outdoor General

This document discusses outdoor lighting and the human eye's response to light. It notes that traditional lighting methods are inefficient and consume high energy to produce light. The eye perceives light differently under varying intensities and colors. Traditional lighting standards are based on daylight vision but the eye behaves differently at night, seeing best in the blue-green spectrum. The document introduces Ellipz lighting, which produces light tuned to the eye's night vision through specific LED combinations without phosphors. This allows better vision with less energy by providing optimal spectral composition for indoor and outdoor applications.

Outdoor Lighting Ronald van Triest CEO
Traditional methods of producing light The conventional way of producing light is by burning From candle light to light bulb to HID. Candle Light Burning Wax Incandescent/CFL Burning Metal/Gas HID/HPS Burning Gas • Burning process is not efficient • Consumes high amount of energy to produce light • Efficiency ~1%
What is light? • Light is measured and expressed in lumen (light intensity) and lux (light per square meter • Quality of light is measured and expressed in Color Rendering Index (CRI)
How it started? • Focus on better vision • Understand how the eye works • Understand how light works
The current standard (1931)- Lighting defined The eye sensitivity curve V(λ) is based on measurement at photopic light levels measured with a 2° view angle (foveal). CIE standard 1931. The cones in the eye can see light from blue to deep red with the highest sensitivity in green/yellow area. One Watt of energy converted to light at 100% efficiency results in 683 lumen.
Our eyes behave differently at night than during the day -- During the day (at Photopic light levels) our vision is the best at 555 nanometres -- in the night (at scotopic light levels) our visibility is best at 505 nanometres
Light intensity shifts from fotopic to scotopic (very low) click on start
Functioning of the eye is different for Outdoor vs Indoor
Eye dynamics • The human eye perceives light different under varying intensities or color • A lux meter does not show that • Vision and sight is not the same under composed colors • Leds allow spectral combinations for optimal vision • Science is questioning the lumen standard Source: http://adsabs.harvard.edu/abs/2009OptEL...5..265J
The Anatomy • All eyes work the same around the world • Cones are for color and day light = 5,000,000 • Rods are for motion and night vision = 120,000,000 11 The retina
Better Sight With Less Light! • Best day sight at yellow-green (cones - 555 nm), night vision at blue-green (rods - 505 nm) • With LEDs, light composition can be chosen more accurate than with conventional light sources, for instance: green at 509 nm (with 2 nm deviation) • Light with a green component gives best sight in street lighting at minimum illumination levels: our visual perception mainly relies on our sensitive rods Standard street lamp Photopic / Daylight Vision Scotopic / Night Vision
Match the light spectrum with the eye – Ellipz Lighting • Light spectrum of Ellipz LED light follows the eye cuve which is shifting left from daylight vision to night light vision. • Standard Sodium lamps are peaking at 555nm which is good for the lux meter but gives poor visibility. • Other Cool-White LED lamps (4000K and above) recreat photopic light with a peak at 555nm (good for lux meter), but again give poor light due to a peak in the blue area due to the usage of 3p and 4p phospors.
Color sensation through RED is intenisty and spectrum depending Low light levels no color vision Ellipz SPD shows colors at 1 lux

Ellipz Mesopic LED-light is adapting to the eye •Human eye is more sensitive to green towards blue at night (Purkinje shift); • Using yellow or white light requires higher wattages to provide good vision; • For OUTDOOR: Ellipz produces a green/blue light to highten visibility at night at low energy levels;
Something fundamentally wrong ! 26 Light directives and standards are based on Photopic lumen This is a serious problem because our eyes behave totally different at night than during daytime. To benefit of the high sensitivity of the rods, light should have the right spectral composition at different intensities. The goal is more sight with less light. Studies show that the ratio between Scotopic (night) en Photopic (day) vision, the so called S/P ratio, is a base which can be used to multiply the lumen with to express the real light perception. COMPETITORs White leds are based on blue chips with 3P or 4P phosphors to convert the blue light into white light with a peak at 555 nm. In outdoor and most interior lighting the maximal eye sensitivity is shifted towards 505 nm. Industrial leds produce the lowest output at that wavelength. Industry spectrum provides lowest light levels at 505 where the eye is most sensitive at night
Some Results - Tunnel lighting 28 lux 6 lux Which side is lighter? This is what the lux-meter reads/measures, but your eyes see different due to night-light and day-light vision. *) picture from former group company Lemnis Lighting BV
New Internationally acclaimed measurement – S/P-ratio 28 lux x S/P 0.63 = 17 6 lux x S/P 3.5 = 21 This is what your eyes sees and then it is correct. Your eyes are not wrong, but measure with the wrong and outdated standards. New measurements are using S/P ratio to express the real light intensity! *) picture from former group company Lemnis Lighting BV

Global Standards in movement (1/2) Industry focus is on More… More…. More Lm/W Lm/$ Eyes are asking for Better… Better… Better See better with less energy (=energy saving) How do we get better light? By making the right spectral composition: high S/P ratio, best vision, lowest energy consumption What is happening to the standards? IES TM 24-13: adjusting illumination measurement using S/P-ratio CIE: working on the Mesopic Task-Force Lites-Asia: twice annual forums discussing S/P-ratio for Asian implementation SEMIcon SEA: making steps to advice and consult governments The movement is there to accept the S/P-ratio as a valid criteria for lighting design and master planning.
Global Standards in movement (2/2) Industry and Countries are slowly accepting and adapting. Panasonic Mesopic Light for Enhanced Security *) copy of Panasonic brochure Philippines has embraced S/P ratio in their program for National Road Lighting
2 versions to answer to diverse global standards Ellipz Mesopic light with S/P ratio of 2.7 (4000CCT) - 3.4 (6000CCT) is ideal at night, but may raise question on absolute requirement of Photopic Lumen. That is why Ellipz has developed a new Streetlighting product that meets the criteria of 90lm/w, but with an S/P ratio of 2.0. type Ellipz SL1 and SL2 Ellipz SL3 Power (w) 25w/40w/60w/80w/120w 60w/75w/120w/150w Photopic Lumen Typcial 36 - 40lm/w Typical 90 lm/w Scotopic Lumen Typical 108 – 120lm/w Typical 180 lm/w Chip composition Red+Green+Cyan+Blue (NO phosphors) Red+Green+Nitrates Lifetime LM 90 @ 50,000hrs LM 90 @ 50,000hrs

CRI 24
The eye needs colors, but the right colors at different light intensities: Ellipz uses RED+GREEN+CYAN to create white (MOON) light The retina In the center part of the retina the ‘sensors’ are the Cones and in the peripherie one uses the Rods. Cones are 96% RED+GREEN.

Hazards of blue light – out of the visual sphere => light dust Blue cones in the eye are not in the central focus of the eye. Therefore blue light is not giving a sharp and detailed vision. An artistic project in Amsterdam had to be stopped creating dangerous situations. In addition the energy level of blue light is affecting the retina and may cause damage to the eye.
SENSITIVITY TO BLUE LIGHT & AGE Human develop natural protection against excess blue light! The older you get, the more blue are filtered! Elderly people see less, specially of the blue light. Glare is therefore more applicable to elderly people and hence impacting road lighting.
Key issue with standard/conventional LED streetlights Conventional LED streetlights are driven by many individual White LEDs with 3p+4p phosphors, each is approx 1+w Limited energy savings: ie. 250HPS replaced by 180w or 150w. Limited lifetime: higher heat output leading to single LEDs malfunction. Faster degradation: due to higher heat output often a black line or fading in the center of the lamp.

Ellipz Lighting – Following the HUMAN EYE In view of providing the most optimal light for the human eye, Ellipz Lighting has developed a 2nd generation of LED ighting technology (SL1, SL2). This is called Mesopic Light, which is combination of Scotopic (=Moon) and Photopic (=Sun) light. The so-called S/P ratio plays an important factor. For strict roadlighting guidelines, Ellipz Lighting has also developed a hybrid version/photopic (SL3) with a lower S/P ratio, but still 25% better than average competition.

    Traditional methods ofproducing light The conventional way of producing light is by burning From candle light to light bulb to HID. Candle Light Burning Wax Incandescent/CFL Burning Metal/Gas HID/HPS Burning Gas • Burning process is not efficient • Consumes high amount of energy to produce light • Efficiency ~1%
  • 4.
    What is light? • Light is measured and expressed in lumen (light intensity) and lux (light per square meter • Quality of light is measured and expressed in Color Rendering Index (CRI)
  • 5.
    How it started? • Focus on better vision • Understand how the eye works • Understand how light works
  • 6.
    The current standard(1931)- Lighting defined The eye sensitivity curve V(λ) is based on measurement at photopic light levels measured with a 2° view angle (foveal). CIE standard 1931. The cones in the eye can see light from blue to deep red with the highest sensitivity in green/yellow area. One Watt of energy converted to light at 100% efficiency results in 683 lumen.
  • 7.
    Our eyes behavedifferently at night than during the day -- During the day (at Photopic light levels) our vision is the best at 555 nanometres -- in the night (at scotopic light levels) our visibility is best at 505 nanometres

    Functioning of theeye is different for Outdoor vs Indoor
  • 10.
    Eye dynamics •The human eye perceives light different under varying intensities or color • A lux meter does not show that • Vision and sight is not the same under composed colors • Leds allow spectral combinations for optimal vision • Science is questioning the lumen standard Source: http://adsabs.harvard.edu/abs/2009OptEL...5..265J
  • 11.
    The Anatomy •All eyes work the same around the world • Cones are for color and day light = 5,000,000 • Rods are for motion and night vision = 120,000,000 11 The retina
  • 12.
    Better Sight WithLess Light! • Best day sight at yellow-green (cones - 555 nm), night vision at blue-green (rods - 505 nm) • With LEDs, light composition can be chosen more accurate than with conventional light sources, for instance: green at 509 nm (with 2 nm deviation) • Light with a green component gives best sight in street lighting at minimum illumination levels: our visual perception mainly relies on our sensitive rods Standard street lamp Photopic / Daylight Vision Scotopic / Night Vision
  • 13.
    Match the lightspectrum with the eye – Ellipz Lighting • Light spectrum of Ellipz LED light follows the eye cuve which is shifting left from daylight vision to night light vision. • Standard Sodium lamps are peaking at 555nm which is good for the lux meter but gives poor visibility. • Other Cool-White LED lamps (4000K and above) recreat photopic light with a peak at 555nm (good for lux meter), but again give poor light due to a peak in the blue area due to the usage of 3p and 4p phospors.

    Ellipz Mesopic LED-lightis adapting to the eye •Human eye is more sensitive to green towards blue at night (Purkinje shift); • Using yellow or white light requires higher wattages to provide good vision; • For OUTDOOR: Ellipz produces a green/blue light to highten visibility at night at low energy levels;
  • 26.
    Something fundamentally wrong! 26 Light directives and standards are based on Photopic lumen This is a serious problem because our eyes behave totally different at night than during daytime. To benefit of the high sensitivity of the rods, light should have the right spectral composition at different intensities. The goal is more sight with less light. Studies show that the ratio between Scotopic (night) en Photopic (day) vision, the so called S/P ratio, is a base which can be used to multiply the lumen with to express the real light perception. COMPETITORs White leds are based on blue chips with 3P or 4P phosphors to convert the blue light into white light with a peak at 555 nm. In outdoor and most interior lighting the maximal eye sensitivity is shifted towards 505 nm. Industrial leds produce the lowest output at that wavelength. Industry spectrum provides lowest light levels at 505 where the eye is most sensitive at night

    Hazards of bluelight – out of the visual sphere => light dust Blue cones in the eye are not in the central focus of the eye. Therefore blue light is not giving a sharp and detailed vision. An artistic project in Amsterdam had to be stopped creating dangerous situations. In addition the energy level of blue light is affecting the retina and may cause damage to the eye.
  • 43.
    SENSITIVITY TO BLUELIGHT & AGE Human develop natural protection against excess blue light! The older you get, the more blue are filtered! Elderly people see less, specially of the blue light. Glare is therefore more applicable to elderly people and hence impacting road lighting.
  • 44.
    Key issue withstandard/conventional LED streetlights Conventional LED streetlights are driven by many individual White LEDs with 3p+4p phosphors, each is approx 1+w Limited energy savings: ie. 250HPS replaced by 180w or 150w. Limited lifetime: higher heat output leading to single LEDs malfunction. Faster degradation: due to higher heat output often a black line or fading in the center of the lamp.

    Ellipz Lighting –Following the HUMAN EYE In view of providing the most optimal light for the human eye, Ellipz Lighting has developed a 2nd generation of LED ighting technology (SL1, SL2). This is called Mesopic Light, which is combination of Scotopic (=Moon) and Photopic (=Sun) light. The so-called S/P ratio plays an important factor. For strict roadlighting guidelines, Ellipz Lighting has also developed a hybrid version/photopic (SL3) with a lower S/P ratio, but still 25% better than average competition.
