Seoul Touts Super-bright White LED

Now going into volume production, the Korean LED maker's new Z-Power P7 is said to emit more light than a conventional 60W bulb.

A new four-chip white LED package from Korea s Seoul Semiconductor is claimed to produce a luminous flux of 900 lumens "“ more than a 60 W incandescent bulb.

The company, which has just moved the products into volume production, says that with a luminous efficacy of 90 lm/W, the Z-Power P7 "can replace a conventional bulb".

Seoul is hoping to see the 10 W-rated emitters applied in high-end flashlights and streetlamps, as well as residential lighting.

According to the firm s web site, the electro-optic characteristics of the new product include a forward voltage of 3.6 V and a forward current of 2.8 A, with each individual LED chip driven at 700 mA.

And, although Seoul s press release states the luminous flux to be 900 lm, the figure on the company s web site claims only 700 lm "“ in fact, the figures reflect the package s "maximum" and the "typical" luminous flux, respectively.

Further details show the P7 to be cool-white in nature, with a correlated color temperature of 6300 K, and a color rendering index of 70.

In comparison, Philips Lumileds Luxeon Rebel range includes a cool-white (6500 K) emitter with a typical luminous flux of 180 lm at 700 mA. Four of those chips could theoretically deliver a typical flux of 720 lm.

Seoul also claims to have some further performance improvements in its locker. Hyuk Won Kwon from the company said: "We will develop new ultra-high-power products emitting over 1000 lm during the third quarter of this year."

The company now believes that the penetration of single LED packages into the general lighting market is "just around the corner".
