Prevaled Light Engines up to 70 percent more efficient

The new Prevaled products are equipped with so-called “Chip-on-Board technology”: individual LEDs are no longer mounted on the printed circuit board, but rather a homogenous surface made of LED chips. This ensures a particularly homogenous light, as one no longer perceives the light of every single LED chip. Prevaled Core Eco Z2 can replace high pressure discharge lamps of up to 70W, energy saving lamps with up to 2x42W 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 is more: in so doing, it is up to 70 percent more efficient than the previous Prevaled generation. 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.

Zhaga: future-oriented luminaire design

The fast pace of the LED era poses new challenges for manufacturers of luminaires: 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. A solution to this situation is provided by OSRAM, with the Prevaled Light Engine system. The Prevaled module offers standardised performance data and at the same time profits from significant improvements in efficiency with regard to LED technology. To ensure that this standardisation is reliable for the future, a great 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.
