3. 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%

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 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

8. Light intensity shifts from fotopic to scotopic (very low)

9. Functioning of the eye 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

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 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

13. 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.

14. Color sensation through RED is intenisty and spectrum
depending
Low light levels no color vision Ellipz SPD shows colors at 1 lux

25. 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;

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

light levels at
505 where the

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.

28. 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!

33. 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.

34. Global Standards in movement (2/2)
Industry and Countries are slowly accepting and adapting.

35. 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.

42. 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.

43. 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.

44. 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.

57. 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.
