Double Digits High Brightness, LED Numeric Display
LBP-602 A / K2 Series
LBP-602 A / K2 series are the numberical display units featuring RO HM’s in-house 4-elem ent
(AlGaInP) high-brightness LED dies.Their lum inous int ensit y is top class in t he industry
while degradation is considerably slow, which helps to keep illumination vividness
almost unchang ed and t he im age of sets high over a long per iod of time.
Features
1) 14.3mm for let t er height, two-lines LED numerical displays.
2) About 10 times m or e lum inous int ensit y than t he conventional
products by use of 4-element LED dies. ( in case of orange color )
3) The same lum inous intensity as the conventional products at t heir 1/10 of current,
which contributes lots to energy-saving of set s .
4) Light- leakage from seg m ents probable with the small display packag es is very rare.
5) Both anode common t ype and cathode com m on type are available in lineup for each color.
