The Seoul Semiconductor LCW100Z1 Improves luminous and thermal efficiency by over 20% simultaneously compared to existing products by enhancing luminous efficiency, adopting a dome lens on a metal substrate and is now available from YEG Opto.

The new 120lm/W high-efficiency and SMD type LED (Part No: LCW100Z1) is ideal for general purpose lighting.  Unlike existing chip LED substrate, the LCW100Z1 delivers over 120lm/W by maximizing luminous efficiency, adopting a dome lens on a metal substrate.  The effect is an improvement in luminous efficiency by over 20% compared to Top View LED by enhancing heat transfer efficiency. In particular, the new patented product shows remarkable cost effectiveness as it raises brightness of the same chip by over two times by the ability to more than double current to the LED.

 As an ultra-thin LED with dimensions of 3.5mm x 2.8mm x 1.6mm, the LCW100Z1 is a high efficiency product that delivers up to 7.8lm (@0.06W) at the low current of 20mA and 14.3lm at the current of 40mA, and its viewing angle is 120 degrees. Another strength of the LCW100Z1 is that its reliability is improved by adopting an optimized thermal design to maximize luminous efficiency needed for lighting. 

The new LCW100Z1 product comes in three ranges of correlated colour temperature’s (CCT); including pure white, warm white and natural white. Samples of the LCW100Z1 were already received favourably by leading lighting appliance manufacturers around the world. As it can immediately replace the existing Top View LED, the LCW100Z1 is expected to be widely adopted for tube-type fluorescent lamps and surface light source lamps. While the expansion of power LED market is restricted due to high price, the LCW100Z1 is also anticipated to serve as a catalyst for expanding the LED lighting market as it allows lighting manufacturers to produce a variety of applied lighting devices with a cost effective solution.

The LCW100Z1 manufactured by Seoul Semiconductor is available from YEG Opto.
