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 LED operates at 85 lumens/Watt and has a CRI of 82 at a relatively low temperature. Newsun says that lamps employing the LED have a very long life because in most cases, the lifetime is based on the life of the driver. And as this LED doesn't have one, it is not affected by this, but by the chip lifetime. The firm also says the price of its AC LED is similar to that of a DC LED.
With a new production line currently under construction, the product is available in bulk quantities and sample orders are also accepted.
