LG Innotek has been making enormous gains in the world of LED lighting since they started LED development back in 2000. Their first major achievement was the development of a mass production white LED chip in 2004, followed by their patented ultra-slim, world first wafer chip on board LED chip in 2009. Fast forward five years and LG Innotek are again creating world firsts. With the help of an Australian company by the name of LED Arts, LG Innoteks world class LED chip-on-board devices are now 100% replaceable!
The new COB LED lighting boards are available for LED flood lights, LED spotlights, and LED downlights. The new clip-out, clip-in design means that a qualified electrician is no longer required to change the diodes (just remember to turn off the power).
This breakthrough design is a huge step forward in making LED flood lights, downlights, and spotlights even more affordable for the average home owner. Not only do these lights lower energy usage but with the new design, home owners can replace the lights themselves without the need to buy new housings, further reducing maintenance costs.
LG Innoteks LEDs are also worth mentioning. The announcement of their new high power LED (mainly used in flood lights and spot lights) saw a 30% increase in lumen efficacy when compared to their previous products. These LED chips put out a whopping 167 lumens per watt, moving LG Innotek into pole position for high power LED production.
As with all lighting products in the past, brighter light is usually accompanied by higher temperatures. LG realised that this high power LED lighting could lead to performance degradation over time and built in their new LED epitaxial growth technology which offers improved heat dissipation than previous products, ensuring the LEDs can maintain their intended lifespan of over 54,000 hours (they passed the US EPA tests with flying colours and were awarded an LM-80 rating).
Along with the new diode technology, LG began to assess the optical design of their LEDs to ensure the optical characteristics of the flood lights and spot lights in particular met the requirements of the consumer. To do this a range of illuminance tests were undertaken. Various optic designs such as uniformity, beam angle control, and omni-directional lamp designs were explored and ray tracing simulations were run, along with real view consumer based tests. All this technical research has led to lighting designs that offer the most efficient, bright, and long lasting LED lights on the market. Its no wonder the likes of Philips and Samsung are scrambling to catch up.
