Packaged LEDs in SSL general lighting to hit 4.6 billion units in 2012
The global consumption value of component-level LEDs in SSL general lighting applications will increase at 37% per year from 2011-2016. Between 2016-2021, the annual average growth rate will be even higher, at 51%
Only 10% of the LEDs used in General Lighting were attributed to Interior lamps in 2011. However, by 2021 the relative market share of LEDs in Interior lighting is forecast to reach 39%.
This is according to ElectroniCast Consultants’ report, “LEDs Used in General Lighting : Global Market Forecast and Analysis (2011-2021).” The consultant firm also says the worldwide volume of packaged LEDs in solid-state lighting (SSL) general lighting will reach nearly 4.6 billion units in 2012.
The global consumption value of component- level (packaged) LEDs in SSL general lighting applications will increase at 37 percent per year (2011-2016). What’s more, there should be faster overall growth in the second-half of the forecast period (2016-2021), with an overall annual average growth rate of 51 percent.

buildings, architectural and other general lighting) applications, in 2011, represented nearly 90 percent share of worldwide consumption.
However, ElectroniCast predicts that in the year 2021, the relative market share of component-level LED use in exterior lamps is forecast to decrease significantly to 61 percent. Having said that, a substantial increase in value is anticipated.
Extending LED lifetime by eliminating the driver
Newsun says the lifetime of lamps employing its AC LED are increased as there is no driver. Instead the lifetime is dependent on the nitride chip lifetime
After seven years of research and development in collaboration with Professor Edson Products, Chinese firm, Newsun has successfully developed a real AC POWER LED; it does not have a shunt connection and is composed of only AC power chips.
Newsun says with the LED, there is no need for a transformer to change the power from AC to DC. What’s more it doesn’t need an LED driver. Not needing either a transformer or driver means that the light source only needs a tiny space.
The use of packaged LEDs in residential, commercial and government exterior general lighting lamps (street, parking-lot, roadway- tunnels, bridges, landscaping, pool/fountain,
