These continuous outer surfaces 11, 12 can be realized by using an excess of polyurethane during foaming in a mould.
  • Figure 5 shows the effect of the foam structure of core 10. This provides for a scattering or diffuse transmission of the incident light 13 coming from the first light sources 5.

Cette lumière présente des propriétés de position, de couleur et d'intensité telles que le devant de cheminée crée l'illusion de comprendre des morceaux de bois et/ou de charbon incandescents. Le devant de cheminée est, de préférence, constitué de mousse polyuréthane.
