A new series of high-power LED modules for lighting
purposes provides illumination levels of up to 540lm. With
a power consumption of only 6.7W, the new Zenigata series
brings LED technology into the category of 60W equivalent
lamps.
Sharp says that a light yield of up to 80lm/W ranks the new
series amongst the best performers in the field in terms of energy
efficiency. The modules also exhibit excellent operating lifetime
specifications of 40,000 hours at +80°C, reducing maintenance
requirements and hence lifetime cost.
Divided into 16 parallel-switched series of three, the new modules
consist of a matrix of 48 LED chips that provide an overall light
output of between 350lm and 540lm. A complementary 190lm
to 280lm series consists of 30 LED chips arranged as ten parallel-
switched series of three.
For both series, an aluminium-ceramic plate measuring 18mm x
18mm x 1.5mm is used as a substrate. This is supplied ready-drilled
with mounting holes, making it possible to fix the modules securely
to a suitable cooling element quickly and simply.
The colour temperature of these white light LED lighting modules
lies within a range of 2,800K to 6,500K. Four tones are available:
normal, warm (comparable to a light bulb) and two types of High
Colour Rendering (HCR).
By using two slightly different phosphorus compounds, the HCR
LEDs attain a Colour Rendering Index (CRI) value of 90. They
thus provide high colour veracity and detail fidelity – essential in
applications where the use of artificial light must not distort image
quality. HCR LED modules are therefore in demand in areas such as
photography, display window decoration and goods presentation,
as well as in medical technology, for instance for surgery lights.
Sharp’s LED light modules are generally suitable for a wide range
of applications. These include interior illumination, for example
in study, reading and desk lamps; decorative lighting; direct
and indirect lighting, for instance for kitchen work surfaces; as
spotlights for stages and building sites and as components for large
LED displays. They are also a long-lasting solution for reading lamps
on public transport such as trains, aeroplanes and buses.
The high-power modules of the 540lm series are particularly useful
in retrofit situations when conventional incandescent lamps are
directly replaced for the sake of lifetime cost and high energy
efficiency.
