Sharp has developed a new series of high-power LED modules. The six new models of the 'MiniZeni' series, part of the Zenigata series, represent another addition to the Sharp LED portfolio. The product variants are characterised by four special features: they have compact outer dimensions and are extremely flat, economical and bright.
Sharp’s 'MiniZeni' LED modules are substantially smaller than the models of the Zenigata LED modules; with dimensions of 15 x 12 x 1.6 millimetres, they only require 56% of the volume of their parent with approximately the same light output. An ceramic plate is also used as the carrier material. With a light output of up to 410 lumens (depending on the module), a substantially improved CRI value of at least 87 at all colour temperatures , Sharp sets new standards in light technology.
The new models are available in two series: a 6.7 W and a 3.6W series. Sharp achieves high flexibility in the lighting design through the modular structure of its LED multi-chip modules. The fundamental components here are individual blue LEDs, coated with phosphorous, that are interconnected in a matrix and installed on the ceramic plate. With the 6.7 W Sharp 'MiniZeni' series, the square LED matrix consists of a total of 45 LEDs that are arranged in fifteen parallel-switched series of threes and achieve a luminous flux of 355 to 410 lm, depending on the model. On the other hand, the matrix of the 3.6 W 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 230 lm.
The benefit of using multi-chip LEDs is that compared with the large-scale single-chip LEDs with approximately the same luminous flux, they are able to offer a more 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 models of the 'MiniZeni' series have a substantially improved CRI value of 87, thanks to various phosphorous mixtures, and as a result ensure colour fastness and attention to detail.
'High colour rendering' LED modules are increasingly in demand in areas such as photography, medical technology (e.g. for OP lights), in shop window decoration and also in the presentation of merchandise. With regard to their high CRI values and their colour temperatures, the series of the 'MiniZeni' LED modules meet the requirements of the international Energy Star Programme, which specifies a CRI value of at least 80. They can thus be used both in innovative LED lighting systems and in those places where fluorescent tubes have previously been used as the light source.
