General Advantages of LED Light Sources white light (daylight, 5600-6000 K) nearly constant color temperature on dimming high reliability of LEDs (50,000 operating hours) reduced cost of ownership (no bulb changing) low energy consumption (~ 20% compared to halogene) wide range input (world wide selling) DC output (no flickering)
Major Advantages of LED Light Sources Cost comparison KL1500 LCD vs KL1500 LED essential reduction in cost of ownership LED lifetime 50,000 h (70% reduced in brightness) - no bulb on stock - no service or downtimes low energy consumption - approx. 80% of energy savings (40 W vs 200 W) weeks / year 52 days / week 5 hrs / shift 8 shifts / day 2 hrs / year 4.160 LED lifetime / hours 50.000 LED lifetime / years 12,02 Bulb lifetime / hours 200 Bulb lifetime / months 0,58 LED wattage / Watt 40 Hal. wattage / Watt 200 Price of bulb / 20 Price of kwh Energy / 0,20 Savings lifetime per year Nr of bulbs 250,0 20,8 Cost of bulbs / 5.000 416 Energy / kwh 8.000 666 Energy cost / 1.600 133 Total / 6.600 549 Cost of lightsource / 599 Payback time / years 1,09
Advantages of LED Light Sources with Fiber Optics significantly higher light intensities can be focussed to a small field of view get more light out of given LED technology (separate housing - more efficient cooling - bigger refelectors - more sophisticated optics) installed base of light guides can be used (just change the light source) full flexibility for realizing different illumination techniques no bulky light source housing covers view to specimen compact housing somewhere behind the microscope
