CA 2344385

An optical component (11) comprises two transparent flat bodies (12, 13) each having grooves (16) or other surface features on one of its faces (15) which interpenetrate when the two bodies (12, 13) are placed face-to-face. The shapes of the grooves (16) or other surfaces features are such that they touch in some places (20, 22, 23) and are spaced from one another in others (18, 19) to form voids (24) within the composite body (11) so formed. These cavities (24) assist in determining total internal reflection of incident light at certain angles. Composites bodies formed from two face-to-face optical components may be used as daylighting screens both to direct light towards an object such as the interior of a building (through an opening) or to screen light from it by diverting it away therefrom.

L'invention concerne un composant (11) optique comprenant deux corps (12, 13) plats transparents comportant chacun sur une de ses faces (15) des creux (16) ou d'autres caractéristiques de surface qui se pénètrent mutuellement lorsque les deux corps (12, 13) sont placés face à face. Les formes des creux (16) ou des autres caractéristiques de surface sont telles qu'ils se touchent à certains endroits (20, 22, 23) et sont espacés l'un de l'autre (18, 19) pour former des vides (24) dans le corps composite (11) ainsi formé. Ces cavités (24) aident à déterminer la réflexion totale intérieure de lumière incidente dans certains angles. On peut utiliser les corps composites formés à partir de deux composants optiques face à face comme filtres d'éclairage naturel pour diriger une lumière sur un objet tel que l'intérieur d'un bâtiment (par une ouverture) ou pour protéger l'objet d'une lumière en l'en éloignant.
