Greentech Lead India: High initial cost of LED lighting
puts the industry out of the reach of masses, according to Electronics For You
(EFY).
The need of the LED lighting industry is to create a commercially feasible
LED lamp that is equivalent to a 60W incandescent bulb, saleable at a cost
of $5 to $10. Several innovations are on the way to achieve this.
EFY has identified some of the latest trends driving LED
lighting industry in its report ‘Future Looks Bright for LED Lighting.’ They
are:
— Omnidirectional LED lamps: Like the incandescent lamp,
the LED must provide an illumination pattern on all sides, if it is to become a
norm in general lighting. The omnidirectional LED technology appears to be a
simple solution to provide a wide illumination pattern
— Organic LEDs (OLEDs) which promise to be thin,
efficient and environment-friendly
— Smart designs to provide an alternative to the
traditional ‘bulb’ that would have a similar form factor and lumen output
— Remote phosphor technology, which is touted to be a
solution to the cost-reduction dilemma
— Alternating-current LEDs, which can produce light
output levels and efficacies of DC-LED assemblies, while eliminating the
AC-to-DC converter and other electronic components that DC LEDs require
— Silicon-based manufacturing, which is being viewed by
the companies as the ultimate path to lower the cost since silicon costs much
less and is widely available
The efficiency and light output of LEDs are increasing
exponentially, effectively doubling every 36 months. The color, quality, light
and efficiency of the light have improved over the last year.
LED technology now provides the basis for a broad
spectrum of application-specific solutions for color temperatures from 2700K to
6500K and various color rendering index (CRI) values from 70 to 95. The
lifetime has also improved significantly to more than 100,000 hours for white
LEDs, bringing down maintenance and replacement costs significantly.
