A memory colour rendition metric, RM 04

HD Retina LED comes from the “unexpected” idea of reversing the usual concept of lighting. HD Retina LED is a high definition LED that saturates either warm and cold colours at the same time, making them pleasant on the human eye and giving them their natural colour. This is why this type of LED is suitable for different applications, when different colour objects need to be illuminated all together, like in general lighting. The HD Retina project develops the intuition of Giorgio Martini, Deputy Chairman of the company: “it’s not so important to see how to light up things in the best way, but...

A MEMORY COLOUR RENDITION METRIC, RM Kevin Smet Light and Lighting Laboratory, Catholic University College Ghent, Belgium - KU Leuven, Postdoctoral Fellow of Research Council Flanders The impact of the light source spectrum on the colour appearance of objects is traditionally quantified by the colour rendering index Ra (CRI) developed by the International Commission on Illumination (CIE). Colour rendition is assessed as fidelity with a CIE reference illuminant: the smaller the colour differences between a set of coloured cards illuminated by the test source and its CIE reference illuminant, the...

WHAT IS COLOUR? The “unexpected Martini philosophy” for lighting designers HD RETINA LED® is the first light source COB (chip on board) developed and patented by a light fixtures manufacturer: Martini MAIN FEATURES: It’s a pleasant light rendering the true colors of the objects. Through an innovative technology, the light source gives back the chromatic information which are inside the human memory (Figure 1). It is a light source which enhances the colors collected by the human mind through different experiences. For this reason it is a light source suitable for several applications, in particular...

Following the success of HD Retina Led after last April’s launch, the technology has been tested and finally used in a number of different sectors, like the world of “Art and Museums”. Art galleries need to meet different criteria when selecting lighting fixtures, above all colour rendering - in terms of the faithful reproduction of the “real” colours of the artworks rather than in terms of CRI, CQS or other traditional metrics. In such a context HD Retina Led has shown amazing results - which Giorgio Martini (the inventor) himself did not expect. HD Retina Led meets, as well, the need for a...

HD Retina led evolution Usually, it is said the average human eye cannot distinguish colour differences falling in a colour space narrower than a 2 or 3-step MacAdam ellipse, but this is true only when settings and objects are individually watched, one by one. In reality, human eye can even see differences smaller than 1-step Mac-Adam whenever we can compare different settings (scenes) all together and, actually, each situation will give us different sensations and a different interaction with our mind. Furthermore, it is important to draw the attention to another prospective: while the market...
