  8. 8. Typical LED replacement lamp - 38 diodes in one package Haitz’s law - light output increases exponentially • electroluminescence discovered in 1907 • first infra-red LED developed in 1961 • first visible (red) LED developed in 1962. • until 1968, LEDs cost upward of $200 per unit. • first high-powered blue LED in 1990s. • blue LED can excite phosphor to produce white light.
  9. 9. Inner workings of an LED (drawing by S-Kei) Effect on life of Luxeon T2 LED by temperature (graph by Luxeon Inc.) • an LED is a semi-conductor device, also referred to as a solid-state device. • when electron meets a hole, a photon is emitted. • colour of light is determined by material. • less wear-and-tear makes devices extremely long-lived. • heat is primary cause of early LED failure.
  10. 10. • an LED cannot make white light, but only a narrow part of spectrum. • we can combine the colour of several LEDs for RGB or additive mixing • or a high-output short wavelength LED to excite a phosphor coating • RGB LEDs can be tuned to give white at the expense of colour stability. • remote phosphor LEDs become physically larger for higher outputs. • high output LEDs need considerable thermal management RGB LEDs combine to produce white light. Remote phosphor LED uses multiple LEDs and a single emission plate to create white light

  12. 12. • colour rendering - how measured? See Student noted • what is the lamp life, how is it measured? See student note • how easy is it to replace the LED module? • how can we control the output? Software driven • what guarantee will the manufacturer give to produce replacement fixtures in the future? • will the LED module be obsolete in the near future?
  13. 13. 1. Lumen (lm) Lumen is the international (SL) unit of luminous flux, a measure of overall light emitted by a light source. Basic Lighting Knowledge
  14. 14. 2. Candela(cd) Candela is the international(sl) unit of luminuous intensity,a measure of light emitted by a light source in a particular direction. Any given light source will have different luminous intensities in different directions considered. [candela = lumen/solid angle]
  15. 15. 3. Beam Angle [Unit:degree] Beam angle is the angle between two directions for which the luminous intensity is 50% of the maxmum intensity as measured in a plan through the nominal beam centerline.Beam angle of a bulb gives an idea of how the light beam spreads away from the beam center.
  16. 16. 4. LUX(lx) Lux is the international(SL)unit of illuminance, a measure of light arriving at a surface, 1 lumen per square foot equals 1 footcandle, while 1 lumen per square meter equals 1 lux . [lux = lumen/m2]
  17. 17. 5. Color Temperature / Correlated Color Temperature(CCT) A black-Body radiator will have a different color when it is heated up to different temperatures (in kevin).The Temperature at which the heated black-body radiator matches the color of the light source is the color temperature of the light source.
  18. 18. 6. Color Rendering Index(CR) Color rendering index ranges from 0-100 ,measures a light source's ability to reproduce the color of various objects being lit by a reference light source, black body radiator(CRI=100) 7. Efficacy (lm/W) Efficacy is the efficiency of a light source to concert electricity energy to light energy which is expressed in lumen output per unit power input (watt) [Efficacy = lumen / wattage] 8. Design Life Time Design life time is the average life of a lighting product when it is operated at nominal lamp voltage,current and controlled working environment. Actual lamp life varies because of any different from those rating condition.
  19. 19. 9. Dimmability Not all lighting prodcuts is designed for dimming function. Dimming a non- dimmable LED lighting product will cause un-predictable result and may affect the life time of the products. The below figure shows the typical input current variation while adjusting the DC voltage input to dimmable and non-dimmable product.
  20. 20. part 3 - how can we use LEDs? LED: The future?
  21. 21. Why LED Lighting Solution ? Technology is changing lives at a pace never before witnessed in all of human history, and with it, the way we see the world. More than a hundred years ago the incandescent filament brought illumination to the night, multiplying human productivity at an exponential rate. Later, fluorescent light rose up as a power-saving alternative to the incandescent. Mengapa LED Penyelesaian Lampu? Teknologi mengubah kehidupan pada kadar yang belum pernah disaksikan dalam sejarah manusia, dan dengan itu, cara kita melihat dunia. Lebih daripada seratus tahun yang lalu, filamen pijar membawa pencahayaan malam, mendarabkan produktiviti manusia pada kadar eksponen. Kemudian, lampu neon bangkit sebagai alternatif yang menjimatkan tenaga kepada pijar
