An elliptical reflector (22) is provided that produces a small, circular, concentrated light beam and a less bright, larger outer elliptical flood light. The outer rim of the reflector (22) is curved, and a matching curved lens (28) is provided for covering the outer rim of the reflector. The curved outer rim of the reflector (22) and the curved lens (28) permit the light beam to extend in a broader horizontal pattern of light, potentially providing close to 180 degrees of illumination. If desired, a portion of the light can be directed downward to light a dark path, for instance.
L'invention concerne un réflecteur elliptique produisant un petit faisceau lumineux, concentré et circulaire et moins vif, et un faisceau lumineux large elliptique extérieur de taille plus importante. Le bord extérieur du réflecteur est courbé, et une lentille courbe coïncidente est prévue pour recouvrir le bord extérieur du réflecteur. Le bord extérieur courbe du réflecteur et la lentille courbe permettent au faisceau lumineux de s'étendre selon un motif de lumière horizontal plus large, produisant une illumination proche des 180 degrés. On peut, si on le souhaite, diriger vers le bas une partie de la lumière pour éclairer, par exemple, un sentier sombre.
