Green light for girls and boys
• Philips Turnhout participated at the S.T.E.M.-event organised by the European school Mol
• S.T.E.M = encourage children to study S(cience) T(echnology) E(ngineering) & M(athematics)
• A team from the Global Technology Development department HID facilitated a workshop “Did you see the light?”
Isabel François and Johan Hendrix help students to build their own spectrometer using a card board box and a CD Rom. With this spectrometer they measured the spectral lines of light from different light sources (CFLi, LED, incandescent lamp, SOX and a living colour lamp)
Ingrid Biermans measures beam de-mixing when the arc of a HID lamp is not in the focal point of a reflector.
Marina Meeuwssen shows how by mixing the 3 basic fluorescence powders (blue, red and green) you can make a powder that lits up white under a UV lamp.
Piet Watté explains the theory behind dispersion or diffraction of light at a prism.
The students found it interesting matter ...
