Description
Tiefer, die Lichtquelle abschirmender Reflektor. Bei Lampen mit tiefen, die Lichtquelle abschirmenden Reflektoren besteht der übelstand, daß ein plötzlicher Übergang von beleuchteter in unbeleuchtete Zone vorhanden ist. Besonders störend ist das bei nahen Wänden, z. B. Häuserfronten, wo scharfe Schattengrenzen entstehen, um so mehr, wenn die Armatur 'vom Winde bewegt wird.Deep reflector shielding the light source. For lamps with deep, The reflectors shielding the light source have the disadvantage that a sudden There is a transition from the illuminated to the non-illuminated zone. Particularly annoying this is the case with nearby walls, e.g. B. House fronts, where sharp shadow borders arise, even more so when the armature is moved by the wind.
Es ist bekannt, die Schattengrenze. durch Anbringung eines ringförmigen Streifens aus lichtstreuendem durchlässigen Matelial, z. B. Opalglas, zu verwischen. Derartige Reflektoren sind aber schwierig herzustellen. Bedeutend einfacher wird derselbe Zweck erfindungsgemäß dadurch erzielt, daß der Reflektor, der aus einem steifen Material, z. B. Emailleblech besteht, um die Strahlenaustrittsöffnung herum mit Aussparungen versehen' wird. Dadurch erhält man eine gewisse Lichtstreuung, die die Schattengrenze aufhebt. Die für Innenbeleuchtungskörper bekannten Stoffbehänge haben zwar eine ähnliche Wirkung, aber sie sind nur mit besonderen . Mitteln anzubringen, teuer und nicht immer zu verwenden. Wenn z. B. der Reflektor im Freien aufgehängt wird oder dem Winde ausgesetzt ist, können selbstverständlich derartige Mittel nicht angewandt werden. Derartige ;Mittel erfüllen also den Zweck, dem der Erfindungsgedanke dient, nur unvollkommen. Der Reflektor nach der Erfindung kann dagegen ohne weiteres auch dort zugewandt werden, wo die Lampe durch Wind oder Luftzug bewegt wird, weil er aus einem starren Körper besteht. Abb. i und 2 stellt je ein Ausführungsbeispiel des Erfindungsgedankens dar. Abb. i stellt einen Reflektor dar, der an der Strahlenaustrittsöffnung mit einer beliebigen Perforierung versehen ist. Abb. 2 zeigt einen Reflektor, der statt der Perforierung Zacken hat.It is well known, the shadow border. by attaching an annular Strip of light-diffusing transparent material, e.g. B. opal glass to blur. Such reflectors are difficult to manufacture. Will be significantly easier the same purpose achieved according to the invention in that the reflector, which consists of a rigid material, e.g. B. enamel sheet is made around the beam exit opening is provided with recesses'. This gives a certain amount of light scattering, which cancels the shadow border. The fabric hangings known for interior lighting fixtures have a similar effect, but they are only special. To raise funds, expensive and not always to be used. If z. B. the reflector hung outdoors such means cannot of course be used or exposed to the wind can be applied. Such; means thus fulfill the purpose that the idea of the invention serves, only imperfectly. The reflector according to the invention, however, can easily also be turned towards where the lamp is moved by wind or draft, because it consists of a rigid body. Fig. I and 2 each represent an embodiment of the inventive concept. Fig. i shows a reflector, which is at the beam exit opening is provided with any perforation. Fig. 2 shows a reflector that instead of the perforation has spikes.
