The HLMP-D150/D155 and HLMP-K150/K155 series, from Avago Technologies, are low current red LED lamps
They are solid state LED lamps which use double heterojunction （DH） AlGaAs/GaAsmAterial technology
ThismAterial gives this family of LEDs a high light output efficiency at very low drive currents
They come in a deep red colour with a dominant wavelength of 637 nanometers
The HLMP-D150/D155 and HLMP-K150/K155 LEDs are ideal for applications where a high light output is required with minimum power
Suitable applications for this family of LEDs include; low power circuits, battery powered equipment and telecommunication indicators.
Features of the HLMP-D150/D155 and HLMP-K150/K155 LEDs：- HLMP-D150/D155：T-1 3/4 （5mm） package - HLMP-K150/K155：T-1 （3mm） package - Minimum luminous intensity specified at 1mA - Wide viewing angle - Low power - Low forward voltage - CMOS/MOS compatible - TTL compatible - Deep red colour
