Osram constructs the world's most efficient LED lamp
Research achievement means yet another innovation surge for LED products
The lamp to be presented by Osram at Light+Building 2014 achieves an almost unprecedented efficiency level of 215 lumens per watt, and therefore generates as much light (lumens) as currently common fluorescent or LED tubes with only half the power consumption (watts). In contrast to research demonstrations until now, the lamp with a length of 1.20 meters has an identical length to traditional fluorescent lamps. The peak efficiency is achieved both with warm and cool white light.
The record is based on a combination of high-efficiency red LED chips and green-whitish Osram LEDs containing a self-developed phosphor that is approaching production maturity. Materials with maximum reflection factors are also used as well as an innovative, integrated optic for minimizing absorption. The lamp is operated with a specifically developed control unit featuring efficiency of 95%. The demonstrator emits 3,900 lumens of warm white light (3000K) and achieves a very good colour rendering index (CRI 90).
The new forms of technology used will be integrated step-by-step into OSRAM product development, and the company is expecting series products with these forms of technology from 2015.
Osram is showing at Light+Building in Hall 2 ("Alte Festhalle") and looks forward to your visit.
