Red LED
L11767
High output power red emitting diode
The L11767 is a high output red LED that delivers light output more than twice that of our previous products. Electric power
required to provide the same brightness as the previous products is reduced by as much as 70%. The L11767 also offers
high reliability since it is a 4-element (AlGaInP) LED.
Features
High radiant output power (more than twice compared to previous products)
13 mW (IF=20 mA typ.)
High reliability
Applications
Optical switches, etc.
