Abstract

Bei einer Bettleseleuchte, insbesondere für Krankenzimmer, die an einer Zimmerwand montiert ist, soll der Ausblendwinkel gegenüber der Senkrechten ca. 30° betragen und gegenüber der Horizontalen ca. 7°, so daß weder der im Bett Liegende noch derjenige im Bett an der gegenüberliegenden Wand vom Licht der Leuchte geblendet wird. Die Bettleseleuchte mit einer länglichen, röhrenförmigen Lampe 2 besitzt eine im unteren Bereich des Leuchtengehäuses 3 vorgesehene Lichtaustrittsöffnung, die von einer lichtdurchlässigen und lichtlenkenden Abdeckung 16 verschlossen ist, die einen unteren, ersten Abschnitt und einen daran anschließenden vorderen aufrechten zweiten Abschnitt 25 besitzt. Der erste, unter der Lampe 2 liegende Abschnitt der Abdeckung 16 weist einen gegenüber der Horizontalen 23 um einen Winkel α von ca. 6 bis 10° geneigten Teil 21 auf, der auf seiner der Lampe 2 zugewandten Seite eine zur Achse der Lampe 2 parallele prismatische Profilierung 24 besitzt und der zweite, an seiner Innenseite ebenfalls eine prismatische Profilierung 26 aufweisende Abschnitt 25 gegenüber der Horizontalen 23 einen Winkel β von ca. 40-50° einschließt.With a bed reading lamp, especially for sick rooms, which is mounted on a room wall, the fade-out angle should be approx. 30 ° with respect to the vertical and approx. 7 ° with respect to the horizontal, so that neither the person lying in bed nor the one in bed on the opposite wall is dazzled by the light of the lamp. The bed reading lamp with an elongated, tubular lamp 2 has a light exit opening provided in the lower region of the lamp housing 3, which is closed by a translucent and light-guiding cover 16, which has a lower, first section and an adjoining front upright second section 25. The first section of the cover 16 lying under the lamp 2 has a part 21 which is inclined by an angle α of approximately 6 to 10 ° with respect to the horizontal 23 and which on its side facing the lamp 2 has a prismatic element parallel to the axis of the lamp 2 Has profiling 24 and the second section 25, which likewise has a prismatic profiling 26 on its inside, forms an angle β of approximately 40-50 ° with respect to the horizontal 23.

Description

Die Erfindung bezieht sich auf eine Bettleseleuchte, insbesondere für Krankenzimmer mit einem vorzugsweise an einer Zimmerwand anbringbaren Leuchtengehäuse mit mindestens einer röhrenförmigen, länglichen Lampe und einem Reflektor und mindestens einer eine im unteren Bereich des Gehäuses vorgesehene Lichtaustrittsöffnung verschließenden, lichtdurchlässigen und der Lichtlenkung dienenden Abdeckung mit einem unteren ersten Abschnitt und einem daran anschließenden vorderen aufrechten zweiten Abschnitt.The invention relates to a bed reading lamp, in particular for hospital rooms, with a lamp housing which can preferably be attached to a room wall and has at least one tubular, elongated lamp and a reflector and at least one light-transmitting cover which closes a light outlet opening provided in the lower region of the housing and serves to guide the light, with a cover lower first section and an adjoining front upright second section.

Das dieser Erfindung zugrundeliegende Problem liegt darin, eine Lichtverteilung bei einer solchen Leuchte in der Form zu erzielen, daß der Ausblendwinkel gegenüber der Senkrechten ca. 30° beträgt und gegenüber der Horizontalen ca. 7°, so daß weder der im Bett Liegende vom Licht der Leuchte geblendet wird noch derjenige im Bett an der gegenüberliegenden Wand. Zur Lösung dieser Aufgabe schlägt die Erfindung vor, daß der erste, unter der Lampe liegende Abschnitt der Abdeckung einen gegenüber der Horizontalen um einen Winkel α von ca. 6 bis 10° geneigten Teil aufweist, der auf seiner, der Lampe zugewandten Seite eine zur Achse der Lampe parallele prismatische Profilierung besitzt und der zweite, an seiner Innenseite ebenfalls eine prismatische Profilierung aufweisende Abschnitt gegenüber der Horizontalen einen Winkel ß von ca. 40 - 50° einschließt.The problem underlying this invention is to achieve a light distribution in such a luminaire in such a way that the cut-out angle is approximately 30 ° with respect to the vertical and approximately 7 ° with respect to the horizontal, so that neither the person lying in bed from the light of the The lamp in the bed on the opposite wall is still blinded. To achieve this object, the invention proposes that the first section of the cover lying under the lamp has a part inclined relative to the horizontal by an angle α of approximately 6 to 10 °, which on its side facing the lamp has an axis the lamp has parallel prismatic profiling and the second section, which likewise has a prismatic profiling on its inside, encloses an angle β of approximately 40-50 ° with respect to the horizontal.

Um die Erfindung zu veranschaulichen, wird sie anhand eines Ausführungsbeispieles näher beschrieben, das in der Zeichnung dargestellt ist. Es zeigen: Fig. 1 einen Querschnitt durch eine Bettleseleuchte; Fig. 2 einen Querschnitt durch die lichtlenkende Abdeckung in einem gegenüber Fig. 1 vergrößertem Maßstab; Fig. 3 die Lichtverteilung und die Fig. 4 und 5 sind Detaildarstellungen verschiedener Abschnitte der Abdeckung in einem gegenüber Fig. 2 vergrößertem Maßstab. Fig. 1 zeigt den Querschnitt einer mit zwei röhrenförmigen Lampen 1 und 2 bestückten Leuchte mit einem Gehäuse 3,das mittels einer Befestigungseinrichtung 4 an einer Wand direkt oder an einem, an einer Wand befestigten Versorgungskanal angeordnet ist. Im wandseitigen Bereich des Gehäuses 3 sind hier verschiedene Versorgungsleitungen 5 - 9 verlegt. Die für den Betrieb der Lampen 1 und 2 erforderlichen Geräte 10 sind in einer wandseitigen Kammer 11 des Gehäuses 2 untergebracht. Eine im wesentlichen waagrecht liegende Trennwand 12 unterteilt das Leuchtengehäuse 3 in einen der Raumbeleuchtung dienenden Abschnitt 13 mit einer lichtdurchlässigen Abdeckung 14 und der Lampe 1 und in die eigentliche Bettleseleuchte 15 mit der Lampe 2 und der Abdeckung 16To illustrate the invention, it is described in more detail using an exemplary embodiment which is illustrated in the drawing. 1 shows a cross section through a bed reading lamp; FIG. 2 shows a cross section through the light-guiding cover on an enlarged scale compared to FIG. 1; 3 shows the light distribution and FIGS. 4 and 5 are detailed representations of different sections of the cover on an enlarged scale compared to FIG. 2. Fig. 1 shows the cross section of a lamp equipped with two tubular lamps 1 and 2 with a housing 3, which is arranged by means of a fastening device 4 on a wall directly or on a supply channel attached to a wall. Various supply lines 5 - 9 are laid here in the wall-side area of the housing 3. The devices 10 required for the operation of the lamps 1 and 2 are accommodated in a wall-side chamber 11 of the housing 2. A substantially horizontal partition 12 divides the luminaire housing 3 into a section 13 serving for room lighting with a translucent cover 14 and the lamp 1 and into the actual bed reading lamp 15 with the lamp 2 and the cover 16

Die von dieser Bettleseleuchte 15 erwartete Lichtverteilung ist in Fig. 3 schematisch dargestellt. Der Ausblendwinkel gegenüber der Vertikalen 17 soll ca. 30° betragen, der Ausblendwinkel gegenüber der Horizontalen 18 ca. 7°, so daß weder der im Bett Liegende von seiner Leseleuchte geblen- det wird noch sein Gegenüber an der gegenüberliegenden Raumwand. In Fig. 3 zeigt die Linie 32 das Ausmaß der Lichtstärke in Abhängigkeit des jeweiligen Winkels zwischen der Vertikalen 17 und der Horizontalen 18.The light distribution expected from this bed reading lamp 15 is shown schematically in FIG. 3. The Ausblendwinkel respect to the vertical 17 should be about 30 °, the Ausblendwinkel relative to the horizontal about 18, so that neither the 7 ° geblen of his reading light lying in bed - will still be det opposite to the opposite chamber wall. In FIG. 3, line 32 shows the extent of the light intensity as a function of the respective angle between the vertical 17 and the horizontal 18.

Für diese Lichtverteilung nach Fig. 3 dient die Abdeckung 16, die in Fig. 2 in einem gegenüber Fig. 1 vergrößerten Maßstab dargestellt ist. Der erste Abschnitt 20, der unter der Lampe 2 liegt, ist gegenüber einer gedachten Horizontalebene 23 um einen Winkel α von ca. 6 - 100 geneigt. Auf seiner der Lampe 2 zugewandten Seite ist eine zur Achse dieser Lampe parallele prismatische Profilierung 24 vorgesehen. An diesen geneigten Teil 21 schließt ein waagrecht liegender Teil 22 an,gegen den hin die Profilierung 24 sozusagen ausläuft, so daß dessen Wände glatt sind und dieser waagrecht liegende Teil 22 geht dann über in den zweiten Abschnitt 25, der ebenfalls an seiner Innenseite, die der Lampe 2 zugewandt ist, eine prismatische Profilierung 26 trägt und dieser Abschnitt 25 ist gegenüber der mehrfach erwähnten Horizontalen 23 um einen Winkel β von ca. 40 - 50° geneigt. Die randseitigen Profilleisten 27 und 28 dienen zur Befestigung der Abdeckung 16 am Gehäuse 3. Aus Fig. 1 ist auch erkennbar, daß die eigentliche Lichtaustrittsebene E des Gehäuses 3 und die Abdeckung 16 mit ihren Abschnitten 20 und 25 nicht deckungsgleich liegen. Die Abdeckung 16 mit ihren Profilierungen und ihren Randleisten 27 und 28 ist einstückig aus einem lichtdurchlässigen Kunststoff gefertigt.The cover 16, which is shown in FIG. 2 on an enlarged scale compared to FIG. 1, serves for this light distribution according to FIG. 3. The first section 20, which lies under the lamp 2, is inclined by an angle α of approximately 6-10 0 with respect to an imaginary horizontal plane 23. On its side facing the lamp 2, a prismatic profile 24 parallel to the axis of this lamp is provided. This inclined part 21 is adjoined by a horizontally lying part 22, against which the profiling 24 runs out, so to speak, so that its walls are smooth and this horizontally lying part 22 then merges into the second section 25, which is also on its inside, which faces the lamp 2, carries a prismatic profile 26 and this section 25 is inclined at an angle β of approximately 40-50 ° with respect to the horizontal 23 mentioned several times. The edge-side profile strips 27 and 28 serve to fasten the cover 16 to the housing 3. From FIG. 1 it can also be seen that the actual light exit plane E of the housing 3 and the cover 16 with their sections 20 and 25 are not congruent. The cover 16 with its profiles and its edge strips 27 and 28 is made in one piece from a translucent plastic.

Fig. 4 veranschaulicht die prismatische Profilierung 24 des Teiles 21 des ersten Abschnittes 20 in einem gegenüber den Fig. 1 und 2 erheblich vergrößertem Maßstab. Daraus ist erkennbar, daß der Öffnungswinkel der prismatischen Profilierungen 24 ca. 45 bis 50° beträgt und die durch den Scheitel S legbare Mittelebene M schräg zu einer gedachten Vertikalebene V steht und daß der Neigungswinkel 29 zwischen diesen beiden Ebenen größer ist als der Neigungswinkel d.des Teiles 21 des ersten Abschnittes 20 gegenüber der Horizontalen 23.FIG. 4 illustrates the prismatic profiling 24 of the part 21 of the first section 20 on a scale that is considerably enlarged compared to FIGS. 1 and 2. From this it can be seen that the opening angle of the prismatic profiles 24 is approximately 45 to 50 ° and the center plane M which can be placed through the apex S is inclined to an imaginary vertical plane V and that the angle of inclination 29 between these two planes is greater than the angle of inclination d. of part 21 of first section 20 with respect to horizontal 23.

Es ist dieser Detaildarstellung nach Fig. 4 ferner entnehmbar, daß die Höhe der prismatischen Profilierungen 24 unter gleichzeitiger Vergrößerung des Öffnungswinkels gegen den horizontalen Teil 22 des ersten Abschnittes 21 der Abdeckung 16 hin abnehmen, wobei diese Abnahme nicht linear ist. Dabei ist die Anzahl der eine gleiche Höhe H aufweisenden prismatischen Profilierungen 24 größer als die Anzahl der eine verringerte Höhe h besitzenden Profilierungen, wobei das Verhältnis dieser Profilierungen ca. 2 : 1 beträgt. Im gezeigten Ausführungsbeispiel liegt über der Basisbreite A (Fig. 4) eine einzige prismatische Profilierung 24. Grundsätzlich ist es möglich, über dieser Basisbreite A mehrere solcher Profilierungen vorzusehen, wobei diese Profilierungen dann in den entsprechenden Winkelverhältnissen zu verkleinern sind ohne dadurch die Lichtverteilung im Prinzip zu beeinflussen. Eine solche Vervielfachung der prismatischen Profilierungen verursacht jedoch erhöhte Werkzeugkosten und einen erhöhten Werkzeugverschleiß.4 that the height of the prismatic profiles 24 decreases with a simultaneous increase in the opening angle towards the horizontal part 22 of the first section 21 of the cover 16, this decrease not being linear. The number of prismatic profiles 24 having the same height H is greater than the number of profiles having a reduced height h, the ratio of these profiles being approximately 2: 1. In the exemplary embodiment shown, a single prismatic profile 24 lies above the base width A (FIG. 4). In principle, it is possible to provide a plurality of such profiles over this base width A, these profiles then have to be reduced in the corresponding angular relationships without in principle influencing the light distribution. However, such a multiplication of the prismatic profiles causes increased tool costs and increased tool wear.

Fig. 5 zeigt die prismatische Profilierung 26 im zweiten Abschnitt 25. Hier beträgt der öffnungswinkel der Profilierung ca..90°. Diese Profilierung 26 ist dabei so angeordnet, daß die Breite B der jeweils oberen Flanke 30 fast dreimal so groß ist wie die Breite B der jeweils unteren Flanke 31.5 shows the prismatic profile 26 in the second section 25. Here, the opening angle of the profile is approximately 90 °. This profiling 26 is arranged such that the width B of the respective upper flank 30 is almost three times as large as the width B of the respective lower flank 31.

Auch bezüglich dieses Abschnittes 25 ist eine Vervielfältigung der Profilierungen 26 denkbar, wie dies schon im Zusammenhang mit dem ersten Abschnitt 20 besprochen worden ist. Es gelten jedoch auch hier für eine solche Vervielfachung die schon erwähnten Nachteile hinsichtlich des Werkzeuges, mit dem eine solche Profilierung gefertigt werden kann.A duplication of the profilings 26 is also conceivable with respect to this section 25, as has already been discussed in connection with the first section 20. However, the disadvantages already mentioned with regard to the tool with which such a profile can be produced also apply to such multiplication.

Aus Fig. 1 ist erkennbar, daß alle Abschnitte der Abdeckung 16, die Profilierungen 24 bzw. 26 aufweisen, unterhalb der durch die Lampe 2 gebildeten Lichtquelle liegen. Die Achsrichtung dieser Lampe 2 ist parallel zur Längsachse der prismatischen Profilierungen. Die Lampe 2 ist darüberhinaus oberhalb der Profilierung 24 des geneigten Teiles 21 des ersten Abschnittes 20 der Abdeckung 16 angeordnet und zwar vorzugsweise oberhalb der rückseitigen, dem vorderen geneigten Abschnitt 25 abgewandten Profilierung.From Fig. 1 it can be seen that all sections of the cover 16, which have profiles 24 and 26, are below the light source formed by the lamp 2. The axial direction of this lamp 2 is parallel to the longitudinal axis of the prismatic profiles. The lamp 2 is also arranged above the profiling 24 of the inclined part 21 of the first section 20 of the cover 16, preferably above the rear profiling facing away from the front inclined section 25.

Vorstehend wurde die Erfindung anhand einer Bettleselampe für Krankenzimmer erläutert, welche auch eine zweite Lampe 1 besitzt, die der indirekten Raumbeleuchtung dient. Diese der Raumbeleuchtung dienende Lampe ist für die Erfindung nicht wesentlich. Auch die andere Ausgestaltung der Bettleseleuchte wie vorstehend beschrieben, insbesondere die Anordnung verschiedener Versorgungsleitungen 5 - 9 ist für die Erfindung nicht wesentlich. Die Bettleseleuchte kann auch anders ausgestaltet sein. Wenn vorstehend beschrieben wurde, daß die Bettleseleuchte an einer Wand oder an einem an einer Wand befestigten Versorgungskanal angeordnet ist, so ist auch dies für die Erfindung nicht zwingend. Es wäre durchaus denkbar, die Bettleseleuchte an einem unmittelbar mit dem Bettgestell verbundenen Träger anzuordnen.The invention was explained above with reference to a bedside reading lamp for hospital rooms, which also has a second lamp 1, which is used for indirect room lighting. This lamp used for room lighting is not essential to the invention. The other design of the bed Reading light as described above, in particular the arrangement of different supply lines 5 - 9 is not essential for the invention. The bed reading lamp can also be designed differently. If it was described above that the bed reading lamp is arranged on a wall or on a supply duct fastened to a wall, this is also not essential for the invention. It would be quite conceivable to arrange the bed reading lamp on a support directly connected to the bed frame.
