the number of sold retrofits is expected to treble within the next five years

The Parathom Classic A75 LED lamp offers customers energy savings of approximately 400 euros per lamp, when considering the entire service life. This lamp is the first LED-substitute for the 75W-light bulb available on the European market and can be used in standard E27-sockets. LED-retrofits – the name of which refers to the new source of light for the old socket – such as the Parathom Classic A75, offer simple access to LED technology for numerous customers. According to a study conducted by the management consulting firm McKinsey, the number of sold retrofits is expected to treble within the next five years and is anticipated to exceed the number of energy-saving lamps by the beginning of the next decade.

The rapid pace of the LED age implies a great challenge for manufacturers of luminaires: the large leaps in performance made in the field of light diodes, as well as the concomitant technical changes have led to the current situation in which virtually every new generation of LED products calls for an entirely new luminaire design. A solution to this situation is offered by standardised LED-modules. LED-modules are units of numerous jointly connected LED. So as to ensure that these are universally applicable, 170 companies in the lighting branch have already joined forces in the so-called “Zhaga Consortium”. The consortium defines certain interface specifications for LED-modules as well as the corresponding electronics required (the control gear). Together these form what is called the “LED-Light-Engine”. In the course of this, mechanical, thermal, photometric and electrical interfaces are taken into account. With these defined parameters, the Zhaga-certified Light-Engines form the counterpart to the standardised lamps of the traditional world of light, such as light bulbs or fluorescent lamps. Specified basic data facilitates planning certainty for the manufacturers of luminaires, providing them with more flexibility, as they are now able to focus on their core business: the actual development of luminaires.

OSRAM will be presenting the first Zhaga-certified light engine at Light+Building 2012: the round LED-module Prevaled Core Z2 for spot- and downlights, which is approximately ten times more efficient than an incandescent lamp and provides performance levels of up to 108 lm/W. What is more, the rod-like LED-modules Prevaled Linear and Prevaled Linear Slim will also be introduced for use in offices, in addition to application in industrial buildings. Their LED-points of light are positioned so close together that the source of light radiated is particularly uniform and evenly distributed.
