PARIS The MiniZeni series from Sharp radiates high efficiency, deliver high color rendering index (CRI) values of up to 87 and boast a long service life whilst measuring only 15x12x1.6mm.
The six new models of the MiniZeni series are characterised by four special features: they have compact outer dimensions and are extremely flat, economical and bright.
A ceramic plate is also used as the carrier material. For the 6.7W Sharp MiniZeni series, the square LED matrix consists of a total of 45 LEDs arranged in fifteen parallel-switched series of threes and achieve a luminous flux of 355 to 410 lumens, 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 lumens.
The benefit of multi-chip LEDs, compared with the large-scale single-chip LEDs of 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 series have a substantially improved CRI value of 87, thanks to various phosphorous mixtures, and thus ensure colour fastness and attention to detail.
With regard to their high CRI values and their colour temperatures, the series of the MiniZeni LED modules correspond to 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.
