Abstract

The invention relates to a lighting fixture with reflecting optics, consisting of a housing which can be sealed by a glass element and in which a lamp with a linear light source in a cylindrical glass bulb and reflectors are accommodated. It is the object of the present invention to create special reflecting optics for a cycle track illuminating system having an extremely widely radiating light distribution and capable of illuminating the cycle tracks with very good uniformity by means of low-power lamps. The lighting fixture according to the invention is characterised by the combination of the following features: a reflector shaped like a gable roof is arranged above the lamp. The ridge line of the roof-shaped reflector is directed downwards and runs parallel to the linear light source at a short distance from the glass bulb thereof. Arranged parallel to the linear light source are two concave reflectors whose edge facing the housing roof runs at a short distance from the lines of the eaves of the roof-shaped reflector. The reflecting surface of the concave reflectors is satin-frosted. Arranged perpendicular to the linear light source are two planar reflectors whose outer corners are bent slightly inwards, and the reflectors surrounding the roof-shaped reflector are tilted slightly outwards. The glass member sealing the housing consists of a clear, smooth glass.

Description

Die Erfindung betrifft eine Leuchte mit Spiegeloptik, bestehend aus einem mit einem Glaskörper, der als Lichtaustritt dient, verschließbaren Gehäuse, in welchem eine Lampe mit einer linienförmigen Lichtquelle in einem im wesentlichen zylindrischen Glaskolben und Reflektoren untergebracht sind.The invention relates to a luminaire with mirror optics, consisting of a housing which can be closed with a glass body which serves as a light outlet and in which a lamp with a linear light source is accommodated in an essentially cylindrical glass bulb and reflectors.

Derartige Leuchten sind entsprechend den verschiedensten Einsatzzwecken in den verschiedensten Ausführungsformen bekannt geworden. Durch die Anordnung und Gestaltung der Reflektoren im Inneren des Leuchtengehäuses und durch ihre Zuordnung zu der Lampe läßt sich die ausgeleuchtete Fläche unter der Leuchte variieren. Im allgemeinen wird gewünscht, daß eine rechteckige Fläche möglichst gleichmäßig unter der Leuchte ausgeleuchtet wird, um den Lichtstrom möglichst gleichmäßig auf die Nutzfläche zu leiten. Derartige rechteckige Flächenausleuchtungen werden nicht nur in Räumen, sondern vor allem auch auf Straßen gewünscht. Sie lassen sich nur mehr oder weniger so realisieren, daß sie den Anforderungen genügen, weil die Beleuchtungsstärke naturgemäß umso größer wird, je näher sich der ausgeleuchtete Ort an der Leuchte befindet.Luminaires of this type have become known in a wide variety of embodiments in accordance with a wide variety of uses. Due to the arrangement and design of the reflectors inside the lamp housing and their assignment to the lamp, the illuminated area under the lamp can be varied. In general, it is desired that a rectangular area be illuminated as evenly as possible under the lamp in order to direct the luminous flux as evenly as possible onto the usable area. Rectangular surface lighting of this type is desired not only in rooms, but above all on streets. They can only be realized more or less in such a way that they meet the requirements because the illuminance naturally increases the closer the illuminated location is to the luminaire.

Als Lampen werden im Straßenverkehr vorzugsweise Natriumdampf-Hochdrucklampen verwendet, hier ist das Verhältnis von Lichtpunkthöhe zu Lichtpunktabstand 1:3 bis 1:5. Bei Straßen besteht meist die Möglichkeit, eine relativ hohe Lichtpunkthöhe zu realisieren.As lamps are preferred in road traffic High pressure sodium vapor lamps are used, here the ratio of mounting height to mounting distance is 1: 3 to 1: 5. On roads, there is usually the option of realizing a relatively high mounting point.

Eine aus der DE 37 10 241 bekannte Leuchte weist eine linienförmige Lichtquelle in Form einer Natriumdampflampe mit zylindrischem Kolben auf, der koaxial von einem teilzylindrischen Refektor zu etwa 240° umhüllt ist.A luminaire known from DE 37 10 241 has a linear light source in the form of a sodium vapor lamp with a cylindrical bulb which is coaxially enveloped by a partially cylindrical refector at approximately 240 °.

Eine andere bekannte Leuchte für die Beleuchtung von Straßen und Plätzen ist aus der DE 81 38 119 U1 bekannt geworden. Sie besteht aus einem mit einem Glaskörper verschließbaren Gehäuse, in welchem eine Natriumdampf-Hochdrucklampe und Reflektoren untergebracht sind. Die Natriumdampf-Hochdrucklampe weist einen beschichteten Ellipsoid-Glaskolben auf. Zwischen dem Dach des Gehäuses und der Lampe ist eine ebene, diffus reflektierende weiße Platte angeordnet, welche von vier schräg gestellten Reflektoren umgeben ist, von denen zwei längliche Reflektoren Konkavspiegel sind. Alle Reflektoren in dieser Leuchte weisen eine hochwertig verspiegelte völlig glatte Oberfläche auf. Die Möglichkeiten, mit diesen Leuchten gute Gleichmäßigkeiten bei der Ausleuchtung der Nutzflächen zu erreichen, sind begrenzt.Another known lamp for illuminating streets and squares has become known from DE 81 38 119 U1. It consists of a housing that can be closed with a glass body, in which a high-pressure sodium lamp and reflectors are housed. The high pressure sodium vapor lamp has a coated ellipsoidal glass bulb. A flat, diffusely reflecting white plate is arranged between the roof of the housing and the lamp, which is surrounded by four inclined reflectors, of which two elongated reflectors are concave mirrors. All reflectors in this lamp have a high quality mirrored, completely smooth surface. The possibilities for achieving good uniformity in the illumination of the usable areas are limited.

Besonders problematisch ist die Beleuchtung von Radwegen, weil diese viel schmaler als Straßen sind, aus Kostengründen die Anzahl der Leuchten meist geringer bemessen wird und weil - Radwege verlaufen oftmals unter Bäumen - die Lichtpunkthöhe niedriger als bei Straßen anzusetzen ist. Für Radwege werden Leuchten benötigt, die ein schmales, weites Lichtband hoher Gleichmäßigkeit von einer niedrigen Lichtpunkthöhe liefern. Das sind Forderungen, die sich mit den bisherigen Leuchten nicht realisieren lassen. Meist sind die Lichtbänder viel breiter als benötigt, die Lichtpunktabstände viel zu kurz, und die Gleichmäßigkeit der Ausleuchtung ungenügend. Die gleiche Problematik ergibt sich bei der Beleuchtung von Zäunen und anderen langgestreckten schmalen Gegenständen.The lighting of cycle paths is particularly problematic because they are much narrower than streets For reasons of cost, the number of luminaires is usually smaller and because - bike paths often run under trees - the light point height is lower than for roads. Luminaires are required for cycle paths that provide a narrow, wide light band of high uniformity from a low mounting point height. These are requirements that cannot be met with previous luminaires. Most of the time, the light strips are much wider than required, the light point distances are too short, and the uniformity of the illumination is insufficient. The same problem arises when lighting fences and other elongated narrow objects.

Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der vorliegenden Erfindung, eine spezielle Spiegeloptik für die Beleuchtung von Radwegen, Zäunen und ähnlichen schmalen Gegenständen mit extrem breit strahlender Lichtverteilung zu schaffen, die die Radwege und sonstigen Gegenstände mit Lampen kleiner Leistung bei niedriger Lichtpunkthöhe mit sehr guter Gleichmäßigkeit auszuleuchten vermag.The invention avoids the disadvantages of the prior art. It is the object of the present invention to create a special mirror optic for the illumination of cycle paths, fences and similar narrow objects with extremely wide light distribution, which can illuminate the cycle paths and other objects with lamps of low power at a low mounting height with very good uniformity.

Die erfindungsgemäße Leuchte zeichnet sich durch die Kombination folgender Merkmale aus:

  • 1.1 über der Lampe ist ein satteldachförmiger Reflektor angeordnet,
  • 1.2.der satteldachförmige Reflektor besteht aus zwei ebenen reflektierenden Flächen und weist eine Firstlinie auf,
  • 1.3.die Firstlinie des dachförmigen Reflektors verläuft parallel zur linienförmigen Lichtquelle ,
  • 1.4.die Firstlinie des dachförmigen Reflektors ist der Lampe zugekehrt und die Trauflinien des dachförmigen Reflektors sind dem Dach des Gehäuses zugekehrt,
  • 1.5.die so nach unten gerichtete Firstlinie weist zum Glaskolben der Lampe einen geringen Abstand auf,
  • 2.1 der Glaskolben der Lampe ist glasklar durchsichtig
  • 2.2.der das Gehäuse (1) verschließende Glas- oder Kunststoffkörper (9) besteht aus einem klaren glatten Glas oder Kunststoff
  • 3.1.parallel zur linienförmigen Lichtquelle sind zwei Konkavreflektoren (Schalenspiegel 13) angeordnet,
  • 3.2.deren dem Gehäusedach zugewandter Rand verläuft in geringem Abstand von den Trauflinien des dachförmigen Reflektor
  • 3.3.die reflektierende Oberfläche der Konkavreflektoren ist seidenmatt
  • 4. senkrecht zur linienförmigen Lichtquelle(20) sind zwei ebene Reflektoren angeordnet,
  • 5. die den satteldachförmigen Reflektor umgebenden Reflektoren sind leicht nach außen geneigt,
Diese Leuchte ist als Radwegleuchte hervorragend geeignet, weil sie ein sehr schmales, langgestrecktes Lichtbald von hoher Gleichmäßigkeit bereits bei niedriger Lichtpunkthöhe liefert. So läßt sich bereits mit einer 50 Watt Natriumdampf-Hochdrucklampe ein etwa 3 m schmales Lichtband von 44 m Länge bei einer Lichtpunkthöhe von 5 m erzielen, wobei an allen Stellen dieses Lichtbandes die Beleuchtungsstärke von 1 lux nicht unterschritten wird.The lamp according to the invention is characterized by the combination of the following features:
  • 1.1 a gable roof-shaped reflector is arranged above the lamp,
  • 1.2. The gable roof-shaped reflector consists of two flat reflecting surfaces and has a ridge line,
  • 1.3. The ridge line of the roof-shaped reflector runs parallel to the linear light source,
  • 1.4. The ridge line of the roof-shaped reflector faces the lamp and the eaves lines of the roof-shaped reflector face the roof of the housing,
  • 1.5. The ridge line pointing downwards is at a short distance from the glass bulb of the lamp,
  • 2.1 the glass bulb of the lamp is crystal clear
  • 2.2. Of the housing (1) closing glass or plastic body (9) consists of a clear smooth glass or plastic
  • 3.1. Two concave reflectors (shell mirror 13) are arranged parallel to the linear light source,
  • 3.2. Whose edge facing the housing roof runs at a short distance from the eaves lines of the roof-shaped reflector
  • 3.3. The reflective surface of the concave reflectors is semi-gloss
  • 4. two flat reflectors are arranged perpendicular to the linear light source (20),
  • 5. the reflectors surrounding the gable roof-shaped reflector are slightly inclined outwards,
This luminaire is ideally suited as a cycle path luminaire because it delivers a very narrow, elongated light beam of high uniformity even at a low mounting point height. This means that a 50 watt high pressure sodium lamp can be used to create an approximately 3 m narrow light band of 44 m length with a light spot height of 5 m, with the illuminance not falling below 1 lux at all points of this light strip.

Die Erzeugung dieses schmalen Lichtbandes bei niedriger Lichtpunkthöhe ist darauf zurückzuführen, daß der satteldachförmige Reflektor das von ihm reflektierte Licht auf die Konkavspiegel reflektiert, die dann das Licht in einem schmalen Band weit ausbreiten, was durch die Oberflächenbeschaffenheit der Spiegel unterstützt wird.The generation of this narrow band of light at a low light spot height is due to the fact that the gable roof reflector reflects the light reflected by it onto the concave mirrors, which then spread the light widely in a narrow band, which is supported by the surface properties of the mirrors.

Bei Bestückungen mit einer 70 W-T Natriumdampf-Hochdrucklampe sind bei einer Lichtpunkthöhe von 6 m unter Zugrundelegung eines Minimalwertes der horizontalen Beleuchtungsstärke von 1 lux Leuchtenabstände bis zu 50 m möglich.When equipped with a 70 W-T high-pressure sodium vapor lamp, with a light point height of 6 m and based on a minimum value of horizontal illuminance of 1 lux, luminaire spacings of up to 50 m are possible.

Wichtig ist dabei, daß die Leuchten einen klaren, glatten Lichtaustritt in Form eines durchsichtigen wannenförmigen Körpers erhalten, weil damit die extreme Breitstrahlung sowie die Blendungsbegrenzung unproblematisch eingehalten werden können.It is important that the luminaires receive a clear, smooth light emission in the form of a transparent trough-shaped body, because the extreme wide radiation and the glare limitation can be easily maintained.

Aber nicht nur für Radwegbeleuchtungen eignet sich diese extrem breitstrahlende Leuchte, sie kann ebenso für Zaunbeleuchtungen, Bahnsteigbeleuchtungen, Fußwegbeleuchtungen, Beleuchtung schmaler Brücken und für viele andere Zwecke eingesetzt werden.But this extremely wide beam light is not only suitable for cycle path lighting, it can also be used for fence lighting, platform lighting, footpath lighting, lighting of narrow bridges and for many other purposes.

Der als Lichtaustritt dienende, das Gehäuse nach unten verschließende Glaskörper braucht nicht unbedingt aus Glas hergestellt zu werden, er kann auch aus einem glasklaren glatten Kunststoff hergestellt sein.The glass body serving as a light outlet and closing the housing downward need not necessarily be made of glass, it can also be made of a crystal-clear, smooth plastic.

Zweckmäßig ist es, wenn die Konkavreflektoren einen Radius von 218 mm ± 20 mm aufweisen.It is useful if the concave reflectors have a radius of 218 mm ± 20 mm.

Weiterhin ist es zweckmäßig, wenn die Ebene des dachförmigen Reflektors einen Winkel von 135° + 15° einschließen.Furthermore, it is expedient if the plane of the roof-shaped reflector enclose an angle of 135 ° + 15 °.

Es hat sich als zweckmäßig erwiesen, wenn die den dachförmigen Reflektor umgebenden stirnseitigen Reflektoren einen Neigungswinkel von 105° ± 15° aufweisen.It has proven to be expedient if the front reflectors surrounding the roof-shaped reflector have an inclination angle of 105 ° ± 15 °.

Von besonderer Wichtigkeit für die lichttechnische Charakteristik dieser Leuchte ist der Reflexionsgrad der Reflektoren. Zweckmäßigerweise wird dieser so gewählt, daß der dachförmige Reflektor den Reflexionsgrad diffus 14 % ± 5 % total 87 % ± 5 %
und die konkaven Reflektoren den Reflexionsgrad diffus 82 % ± 5 % total 86 % ± 5 %
aufweisen.The reflectance of the reflectors is of particular importance for the lighting characteristics of this lamp. This is expediently chosen so that the roof-shaped reflector has the degree of reflection diffuse 14% ± 5% total 87% ± 5%
and the concave reflectors the reflectance diffuse 82% ± 5% total 86% ± 5%
exhibit.

Die Lichtausbeute und die gleichmässige Ausleuchtung lassen sich noch dadurch verbessern, daß die Außenecken der senkrecht zur linienförmigen Lichtquelle angeordneten ebenen Reflektoren leicht nach innen abgebogen sind.The luminous efficacy and the uniform illumination can still be improved in that the outer corners of the perpendicular to the linear light source are arranged flat reflectors are slightly bent inwards.

In dem Gehäuse 1, welches mit einer Befestigungsvorrichtung 2 an einem Masten 3 befestigt wird, sind einerseits in einem gesonderten VG-Raum 4 elektrische Bauteile 5 für das Zünden und Betreiben der Lampe 6 untergebracht. Weiter ist im Gehäuse 1 das Reflektorsystem 7 untergebracht, in welches die Lampenfassung 8 hineinragt. Zu der Seite hin, zu der die Lampe abstrahlt, ist das Gehäuse 1 durch ein Leuchtenglas 9 verschlossen. Es ist wichtig, daß dieses Leuchtenglas, welches wannenförmig geformt ist, aus einem klaren, glatten Glas oder Kunststoff hergestellt ist.In the housing 1, which is fastened to a mast 3 with a fastening device 2, electrical components 5 for the ignition and operation of the lamp 6 are accommodated on the one hand in a separate VG room 4. The reflector system 7, into which the lamp holder 8 projects, is also accommodated in the housing 1. On the side to which the lamp emits, the housing 1 is closed by a lamp glass 9. It is important that this lamp glass, which is trough-shaped, is made of a clear, smooth glass or plastic.

Das Reflektorsystem ist auf eine Grundplatte 10 montiert, an welcher eine Halterung 11 für die Lampenfassung 8 angeordnet ist. Die Grundplatte 10 trägt einerseits einen satteldachförmigen Reflektor 12, zwei konkave gegeneinander gerichtete Schalenspiegel 13 und zwei Stirnseitenspiegel 14, von denen der eine eine Durchtrittsöffnung 15 für die Lampenfassung 8 aufweist. Die Stirnseitenspiegel 14 sind in ihren Eckbereichen 16 zur Mitte des Reflektorsystems hin abgebogen, so daß sich ein fast geschlossenes Spiegelsystem ergibt.The reflector system is mounted on a base plate 10, on which a holder 11 for the lamp holder 8 is arranged. The base plate 10 carries on the one hand a gable roof-shaped reflector 12, two concave shell mirrors 13 directed towards one another and two end face mirrors 14, one of which has a passage opening 15 for the lamp holder 8. The end face mirrors 14 are bent in their corner regions 16 towards the center of the reflector system, so that an almost closed mirror system results.

Der satteldachförmige Reflektor 12 besteht aus zwei ebenen Flächen, die stumpfwinklig zueinander stehen und zwischen sich einen First einschließen. Der First ist der Lampe 6 zugewandt, die Traufen sind dem Dach des Gehäuses 1 zugewandt.The gable roof-shaped reflector 12 consists of two flat surfaces which are at an obtuse angle to one another and enclose a ridge between them. The ridge faces the lamp 6, the eaves face the roof of the housing 1.

Die Stirnseitenspiegel sind unter einem Winkel von etwa 105° geneigt, während der Neigungswinkel der Schalenspiegel an der Grundplatte etwa 135° beträgt und sich dann auf etwa 90° vermindert. Der satteldachförmige Reflektor weist einen Dachwinkel von etwa 135° auf (gemessen unter der Firstlinie 17).The end face mirrors are inclined at an angle of approximately 105 °, while the angle of inclination of the shell mirrors on the base plate is approximately 135 ° and then decreases to approximately 90 °. The gable roof-shaped reflector has a roof angle of approximately 135 ° (measured under the ridge line 17).

Die Lampe 6 weist einen zylindrischen Kolben aus glasklarem Glas auf. Unmittelbar neben dem Kolben der Lampe 6 und parallel zur Längsachse der Lampe 6 befindet sich die nach unten gerichtete Firstlinie 17 des dachförmigen Reflektors 12. Das ist eine Grundbedingung zur Erreichung des erfindungsgemäßen Effektes.The lamp 6 has a cylindrical bulb made of crystal-clear glass. Immediately next to the bulb of the lamp 6 and parallel to the longitudinal axis of the lamp 6 is the downward ridge line 17 of the roof-shaped reflector 12. This is a basic condition for achieving the effect according to the invention.
