Standby goes red with the first red LEDs from Siemens
In 1971, Siemens launches the first red LEDs. The diodes emit light with a wavelength of 660 nanometers.
The LEDs quickly replace bulbs in many applications including mode displays in consumer electronics.
Red becomes the standard color for standby modes. The advent of LEDs significantly cuts electricity consumption.
Today, almost two-thirds of all Infineon products help manufacturers use energy more efficiently.
With the PACE-Pak for DC drives and power supplies, IR becomes the first company to introduce the power module concept.
IR Sells Dallons to Ohio Nuclear, Inc., a subsidiary of BBC Industries.
