Traditional LEDs have been used for display and indication applications for a long time now. The intrinsic benefits of LED technology are documented and well-known, and include, preservation and power savings, in addition to performance features that are taken for granted by electronics-savvy consumers such as reliability, durability, longer lifespan, and brightness levels and consistent color. These advantages, together with society's emergent ecological concerns and the consequent demand for energy-efficient, green products, have continued to drive the development of LEDs for challenging new markets and industries, such as general illumination for residential and commercial buildings.
