M. LEDS: SAVE MONEY, SAVE THE PLANET 1 MILLION YEARS AGO Fire 4,500 TO 3,300BC The First Oil Lamps 200BC Earliest Use of Candles 1870'S The Incandescent Lightbulb 1927 The First LED 2012 EU Bans the Sale of Incandescent Bulbs WHAT WILLWE DO NOW? COMPACT INCANDESCENT INDUCTION LEDS FLUORESCENTS BULBS LIGHTING (CFL) Fluorescent lamps LED lights use a chip and an optical lens to provide The best kept secret in the lighting indus- try, but becoming a key player. The most common type of bulb in the household. These are designed to replace traditional illumination. incandescent bulbs. lamps work on technology developed around 100 years ago. ADVANTAGES ADVANTAGES ADVANTAGES 1.Energy Efficient - Can save up to 60% of energy of a con- ventional lamp. 1. Use up to 80% less energy than traditional bulbs 1.Can use up to 90% less energy than ADVANTAGES 1.Low initial purchase conventional bulbs. 2. Low operating temperature cost 2.Lower running 2.Very Long Life - Up to 60,000 hours 2.Excellent colour costs reduces risk of rendering 3.No UV 3.Quality of light is maintained over a burning 3. Cost savings over the bulb's lifetime 3.Ease of dimming 4.Cool to touch low radiated heat 4.Immediate full light when switched on long period of time. 5.Long Life, some DISADVANTAGES up to 100,000 hours DISADVANTAGES 1. Output can be affected by DISADVANTAGES 1.High initial purchase cost 1.Low Efficacy - only 8-15 lumens per watt (Not energy efficient) DISADVANTAGES temperatures and frequent switching on and off 2. Take time to 1.Higher initial purchase cost 2.Very little information in the 2.High Running Cost 2.Higher heat dissipation market compared to other light sources. 3.High Heat Output (94% of energy produced is heat, only 6% is light) provide full light output after switching on WHERE TO USE THEM? - Because of the falling price of LED lamps, it is becoming logical to use them for all 4.Bulb Surface DISCHARGE WHERE TO USE become extremely LIGHTING THEM? - Where possible - ALL Incandescent lamps should be replaced with CFLS hot GOING FORWARD: light sources, The sale of higher wattage incandescent bulbs has now been But especially for fittings that are used frequently or for long periods of LIFESPAN IN YEARS: banned by the EU. - A close alternative is Tungsten Halogen. time. - Halogens use halo- gen gas to operate. LIFESPAN IN YEARS: - They have a longer life and a brighter white light. Discharge Lamps are most popular for outdoor lighting like street lighting. - But cannot be used in all the same ADVANTAGES 1.High Efficacy, therefore efficient applications. lighting LIFESPAN IN YEARS: 2.Long life 6,000 to 12,000 hours !! 3.Good colour rendering DISADVANTAGES 1.Take time to reach its full light after switch on 2.High energy con- sumption compared to induction. WHERE TO USE THEM? Floodlighting, street lighting, stadium lighting, display lighting. Any large areas that need to be very well lit. SAVE MONEY 8% £16 £70 Lighting accounts for 8% of a typical household energy Replacing a 50W halogen downlighter Banning incandescent bulbs will reduce household electricity bills by £16 a year by with a 6W LED will bill save £70 over the 2020 bulb's lifetime SAVE THE PLANET 50x 11m 20 - 25% The EU will save enough CFLS use 20 - 25% of the electricity of a comparable LED bulbs last 50 times as long as energy to power 11 million households incandescent bulbs a year by banning incandescent bulbs incandescent bulb METEOR electrical.com www.meteorelectrical.com http://ec.europa.eu/energy/lumen/index_en.htm http://www.energysavingtrust.org.uk/Electricals/Lighting
