Landscape Analysis: Connected Lighting System
Infrastructure and Technology Management: Contributions from the Energy, Healthcare and Transportation Sectors
The lighting industry has gone under major transformations in recent decades. These changes are both at components/luminaires and system level. In 1999, Haitz stated that lumen per package will increase by a factor of 30 and the cost per lumen will decrease by factor of 10 . This is also known as Haitz’s law . In 2011, Haitz’s law is revisited; though the cost per lumen decremental rate remained the same, lumen per package incremental rate dropped to 20 . According to revised Haitz’s law, LED has entered to era that can overcome its adoption barrier—high lamp price and low light output per emitter [2, 4]—in general lighting section. Next Generation Lighting Industry Alliance (NGLIA)’s presentation to the Department of Energy (DOE) shows that LED would disrupt the traditional lighting resource and dominate the lighting market by 2020 .
