First Chip-on-Board LED from OSRAM Opto Semiconductors, Soleriq E LED for Downlights with High Performance Requirements

Downlights provide high-quality background lighting in professional applications. These include shopping malls, offices, industrial buildings and high-end residential premises. The luminaires need a high luminous flux for their light to have the right effect. This is precisely what the new Soleriq series provides, the first chip-on-board LED from OSRAM Opto Semiconductors. Even at high application temperatures they create the basis for highly efficient luminaires with a luminous flux of 1500 lm to 4500 lm.

Technical Data:

Dimensions 30 mm x 30 mm x 1.7 mm (E 30)
36 mm x 36 mm x 1.7 mm (E 45)
Beam angle 120°
Lamp life 50,000 hours
Thermal resistance 0,38 K/W (E 30)
0,25 K/W (E 45)
Typical brightness at 4000 K
(substrate temperature Ts at 85°C)
2700 lm (E 30, 600 mA)
4000 lm (E 45, 880 mA)
Other Metal core board

Only one Soleriq E LED is needed to give a luminaire enough light. This makes designing luminaires much easier because only one component has to be integrated instead of lots of LEDs. The individual chips are all under the conversion layer (chip-on-board), giving the impression of a homogeneous light emitting surface. This ensures a uniform color and light appearance in the luminaire and even coupling into external light-guiding optics is very simple. The light generated can be used with much lower optical losses, which in turn makes the LED lamps and luminaires more efficient. Typical LED benefits such as high energy efficiency and long lifetime have an excellent impact in the downlights.

Wide variety of applications:
The Soleriq E is available in two versions, covering the entire color spectrum from 2700 to 6500 K. Even at a temperature of 85°C, which corresponds closely to the temperature in the application, the two LEDs offer an impressive efficiency of 103 lm/W at 4000 K. At this temperature the larger Soleriq E 45 achieves a typical brightness of 4000 lm (rated current 880 mA); the smaller Soleriq E 30 produces a lumen output of 2700 lm (at 600 mA).

Good color homogeneity is achieved by the narrow white grouping of the Soleriq E, corresponding to a range of 4-step MacAdam ellipses. For solutions that need a particularly high level of color homogeneity, grouping based on 2-step MacAdam ellipses is also available.

Andreas Vogler, Marketing Manager General Illumination at OSRAM Opto Semiconductors, said: “Downlights are in widespread use in many areas such as shop, office and residential lighting but need high lumen packages between 1500 and 4500 lm to perform their task. We can achieve these high values with just one LED component. This makes it easier to couple the light into external optics and to integrate the light source in the luminaire.”
