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.
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 applicationsThe 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.”
