Haitz's law [SEP] named after
a given integrated circuit doubles every 18 to 24 months. Both laws rely on the process optimization of the production of semiconductor devices.
Haitz's law is named after Roland Haitz (1935–2015), a scientist at Agilent Technologies among others. It was first presented to the larger public at Strategies in Light 2000, the first of a series of annual conferences organized by Strategies Unlimited.
Besides the forecast of exponential development of cost per lumen and amount of light per package, the publication also forecast that the luminous efficacy of
Haitz's law
Haitz's law is an observation and forecast about the steady improvement, over many years, of light-emitting diodes (LEDs).
It claims that every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light. It is considered the LED counterpart to Moore's law, which states that the number of transistors in
