Prevaled Light Engines up to 70 percent more efficient
Osram has expanded its portfolio of LED light engines
Osram's latest Prevaled LED Light Engine range now offers up to 70 percent more efficiency. The products of the Prevaled Core Eco Z2 line attain a module efficiency of up to 108 lumen/watt (lm/W).

With its LED Light Engines, Osram offers planning security whilst continually improving LED performance. The firm believes the dimensions, luminous flux and light distribution are the equivalent to the Edison socket in the analogue world of light.
The new Prevaled products are equipped with “Chip-on-Board technology”. In other words, individual LEDs are no longer mounted on the printed circuit board, but are placed to create a surface made of LED chips. This ensures homogenous light, as one no longer perceives the light of every single LED chip.
Osram says the Prevaled Core Eco Z2 can replace high pressure discharge lamps of up to 70W, energy saving lamps with up to 2 x 42W and halogen lamps, each with up to 100W power consumption, and therefore the traditional technologies in the majority of the spotlight and downlight applications.
What's more, it is up to 70 percent more efficient than the previous Prevaled generation. The prerequisite for this, however, is the large portfolio ranging between 800 lm and 5,000 lm. Owing to LED technology, the light does not contain any harmful UV or infrared light components, thus sensitive products such as cosmetics or foodstuffs can also be illuminated. The low heat is given off to the back of the module via standardised thermal interfaces.
The fast pace of the LED era poses new challenges for luminaire manufacturers; the great leaps in performance with regard to the light diodes and the technical changes associated with this, require an entirely new luminaire design with every LED generation.
Osram believes it has solved this problem with its Prevaled Light Engine system. The Prevaled module offers standardised performance data and at the same time profits from significant improvements in LED efficiency. To ensure that this standardisation is reliable for the future, a number of manufacturers have teamed up in the Zhaga consortium.
Standards for LED modules that are supported by numerous manufacturers are developed here. “Our developers cooperate closely with the representatives in the consortium. Thus the future standards can be implemented in our products in a timely manner. In the course hereof, luminaires automatically benefit from the development advances made with LED, without this resulting in cost-intensive changes having to be made to the basic construction,” says Wolfgang Andorfer, Senior Director Solid State Lighting at Osram.
