Title (EN) LIGHTING DEVICE INCLUDING A TRANSPARENT STRUCTURE
(FR) DISPOSITIF D'ÉCLAIRAGE COMPRENANT UNE STRUCTURE TRANSPARENTE
Abstract:
(EN) Embodiments of the invention include a light emitting diode (LED) and a transparent structure disposed over the LED. The transparent structure includes a first surface that reflects light extracted from the LED and incident on the first surface. The transparent structure also includes an exit surface opposite the first surface. The exit surface includes a first area that is textured to diffuse light over a first angular range and a second area that is textured to diffuse light over a second angular range. The second angular range is wider than the first angular range.
(FR) Des modes de réalisation de l'invention comprennent une diode électroluminescente (DEL) et une structure transparente disposée sur la DEL. La structure transparente comprend une première surface qui réfléchit la lumière extraite de la DEL et incidente sur la première surface. La structure transparente comprend également une surface de sortie opposée à la première surface. La surface de sortie comprend une première zone qui est texturée pour diffuser la lumière sur une première plage angulaire et une seconde zone qui est texturée pour diffuser la lumière sur une seconde plage angulaire. La seconde plage angulaire est plus large que la première plage angulaire.
