Sharp Minizeni LED modules are flat and compact

Sharp has developed the Minizeni series of high-power LED modules, which consists of six models.

The product variants are said to have compact outer dimensions and be extremely flat, economical and bright.

Sharp Minizeni LED modules are substantially smaller than the Zenigata LED modules.

With dimensions of 15 x 12 x 1.6mm, they only require 56 per cent of the volume with approximately the same light output.

A ceramic plate is also used as the carrier material.

The modules have a a light output of up to 410 lumens (depending on the module).

The models are available in the 6.7 and 3.6W series.

Sharp achieves high flexibility in the lighting design through the modular structure of its LED multi-chip modules.

The fundamental components are individual blue LEDs, coated with phosphorous, that are interconnected in a matrix and installed on the ceramic plate.

With the 6.7W Sharp Minizeni series, the square LED matrix consists of a total of 45 LEDs that are arranged in 15 parallel-switched series of threes and achieve a luminous flux of 355 to 410lm, depending on the model.

On the other hand, the matrix of the 3.6W consists of a total of 24 LEDs that are arranged in eight parallel-switched series of three and achieve a luminous flux of up to 230lm.

The benefit of multi-chip LEDs, compared with the large-scale single-chip LEDs with approximately the same luminous flux, lies in their homogeneous distribution of heat.

Whereas the heat developing from high-power LEDs has to be transported away over a single point or a very small area, the lower temperatures of multi-chip LEDs resulting from low currents can be distributed and transported away over a larger area.

This results in a substantial simplification of heat management.

The ceramic carrier material is also characterised by a high surface quality, resulting in low surface roughness.

This simplifies connection to the cooling element, making it as seamless as possible and creating excellent heat dissipation.

The colour temperature of the three white-light LED lighting modules lies in the range of 2,700 to 5,000 Kelvin with the shades Warm White and Pure White.

The Minizeni models have a substantially improved CRI value of 87, due to various phosphorous mixtures, and thus ensure colour fastness and attention to detail.

With regard to their CRI values and colour temperatures, the Minizeni modules correspond to the requirements of the international Energy Star Programme, which specifies a CRI value of at least 80.

They can be used in LED lighting systems and in those places where fluorescent tubes have previously been used as the light source.

The luminous LED modules from Sharp are suitable for applications such as office and commercial lighting, street lighting, architectural lighting, display lighting and backlighting.
