LG Chem today unveiled the world's biggest OLED lighting "building installation" at Seoul National University's new main library. LG Chem supplied 1,100 OLED panels used for reading lights.

LG Chem says that SNU adopted OLED lighting because they energy efficient, extremely comfortable to the eyes - and they enable modern designs due to their slim profile. LG Chem supplied 550 desk lamps to the University, and next month they will start marketing those lamps to other customers.

The OLED panels used at SNU are 320x110 mm in size, and feature 60 lm/W, 40,000 hours lifetime and a brightness of 300 - 850 lux.



While this may be the biggest building OLED installation ever, it is a lot smaller than Konica Minolta's 15,000 flexible OLED panel installation at Huisch Tembosch Tulip Festival.

Something that makes me

Something that makes me skeptical about OLED lighting and about which I'm wondering whether it'll ever come up is color temperature. Because sitting in rooms lit with warm light for prolonged periods of time can throw one's body clock off.

Actually OLED enables a wide

Actually OLED enables a wide range of color temperature (and even color-tunable panels), and it emits a third of the harmful blue light compared to LED-based lighting.

 

 

if blue light is missing during the daytime, it is hard to keep awake

if blue light is present during nighttime, it is harder to get asleep

 

I understand the first comment as actually the blue light is what is missing in warm light OLED lighting situations during the day and it will kick-off you sleep cycle

 

same will happen (kicking-off your sleep cycle) if you tend to stare into cold-white blue LEDs at night night

 

for OLED this is not a problem yet, as real cold white (5000 - 6500K) is not available;
