Abstract: The present invention refers to an optical element (1) for controlling a light distribution pattern of a light source (13) radiating light beams (L) to a geometric half-space (H1) being defined by a geometric plane (Pi), wherein the optical element (1) is integrally made of a transparent piece (2) and comprises a base plate (3) of the transparent piece (2), a lens section (4) of the transparent piece (2), and a cavity (5) in the transparent piece (2). The part of the cavity (5) extending through the base plate (3) defines a bottom cavity space (50) which is circumferentially delimited by a redirection surface of the transparent piece and continuously tapers towards the lens section. An angle α of the redirection surface (6), with respect to the geometric plane (P1), at any part along its circumference is defined such that light propagating through the base plate (3) by internal total reflection towards the cavity (5) is redirected at the redirection surface (6) by total internal reflection towards the geometric half-space (H1) and preferably directly into the lens section (4).

Abstract: An ultraviolet light emission device (1) includes: an excimer lamp (2) having an elongated shape and having a light emission surface (2a) that emits ultraviolet light (L) toward an object (W) for irradiation; a light intensity sensor (3) that is disposed around the excimer lamp (2) and detects ultraviolet light (L); and a first reflection member (61) disposed around the excimer lamp (2) and facing a part of the light emission surface (2a) in a longitudinal direction, wherein ultraviolet light (L) emitted from the light emission surface (2a) is reflected by the first reflection member (61) and enters the light intensity sensor (3).

Abstract: A beam-shaping lens includes a first surface including a smooth-shaped concave surface; and a second surface including a convex surface substantially similar in shape to the concave surface. The beam-shaping lens converts a first light beam that is parallel light incident on the first surface and having a light intensity distribution that continuously increases from an outer periphery toward a center, into a second light beam that has a flatter light intensity distribution than that of the first light beam.

Abstract: Die Erfindung betrifft eine Leuchte zur Lichtabgabe eines Direktanteils und eines Indirektanteils, wobei die Leuchte folgendes aufweist: ein Gehäuse und eine transparente Abdeckung, welche das Gehäuse verschließt, wobei in dem Gehäuse LEDs als Leuchtmittel der Leuchte sowie wenigstens ein Reflektor angeordnet sind, und in der transparenten Abdeckung auf einer zum Gehäuse weisenden Seite ein optisches Plattenelement gehalten ist, welches lichtreflektierende Bereiche und lichttransmittierende Bereiche aufweist, wobei die lichtreflektierenden Bereiche des optischen Plattenelements eingerichtet sind, um Licht, welches aus dem Gehäuse auf das optische Plattenelement auftrifft, zum Teil zu dem Reflektor und zum Teil zu Seitenwänden der optischen Abdeckung zu reflektieren, wobei das Licht aus den Seitenwänden der Abdeckung austritt zur Erzeugung des Indirektanteils, und die lichttransmittierenden Bereiche des optischen Plattenelements eingerichtet sind, um Licht aus dem Gehäuse zu einer dem Gehäuse entgegengesetzten Seite der transparenten Abdeckung zu transmittieren zur Erzeugung des Indirektanteils.
