Description

The The present invention relates to an outdoor lamp. Especially The present invention relates to an outdoor lamp which for the illumination of streets, business premises and the like. Furthermore, the present invention relates Invention, a luminaire, the large-scale Illumination of interiors, such as halls, canteens, Gymnasiums, workshops and the like can be used.

Luminaires and in particular luminaires with light wings are known from the prior art. From the WO 2006/060905 A1 For example, an outdoor lamp is known which has two light wings. In this case, the lamp is designed such that the angle of inclination of the lamp wing with respect to an alignment of the two lighting wings can be changed in one plane via an adjusting screw.

Also from the US 2003/0193802 A1 is an outdoor lamp with light wings known. In this case, the luminaire wings are formed as circular segments and attached at their outer ends to a lamp housing and at their inner ends to a lamp rod, which is arranged centrally in the lamp housing. These lights wings are designed adjustable, the outer ends of the lights are connected by springs firmly connected to the lamp housing and only the inner ends of the lights can be moved along the light rod up and down.

Even though known lights, especially outdoor lights swiveling Nevertheless, it is often not possible adequate illumination of the environment around the lamp to guarantee. As a result of this, especially for an illumination of busy traffic areas, a variety of lights necessary to the desired or required illumination to reach, which ultimately too high Acquisition costs, high energy costs and low flexibility related to the lighting task leads.

From that It is the object of the present invention to provide a luminaire whose design makes them highly efficient and flexible illumination of their environment allows and with Help derer thus the number of lights for the desired or required illumination is necessary, can be reduced.

These Task is with a lamp with the features of claim 1 solved. Preferred embodiments are in the specified dependent claims.

Of the Invention is based on the idea of a luminaire instead of as before with two luminaire wings or circular segment-like luminaire wings, the only limited flexibility in adjustability and thus allow illumination, with at least three lighting wings to provide, preferably independently, in particular in terms of their radiation angle of the light, are adjustable. This allows the most efficient flexibility guaranteed in setting, orientation and illumination of the environment become. Thus, a lamp is created, the most diverse Places to different conditions and for most different Lighting tasks can be used while a enables such a good and adaptable illumination of the environment, that only a small number of luminaires per area to be illuminated necessary is. For example, depending on environmental conditions or time of day the orientation of the lights varies will be adapted flexibly.

To the luminaire according to the invention contains a Luminaire body, the at least three preferably next to each other, Having arranged in series lighting wings. The lights wings are provided with bulbs. The transverse direction of the lamp is defined as the direction along which the lights wings are arranged. The longitudinal direction is the one in the plane the lamp lying direction perpendicular to the transverse direction is. At least the outer lights of the lamp body are each one in the longitudinal direction the lamp body extending axis, preferably independently from each other, arranged pivotally.

preferably, the outer lights are over Hinges hinged to the at least one between the outer Luminaire wings arranged middle luminaire wings intended.

Frequent changes at the angles of inclination of the luminaire wings In conventional lights often to failure of the corresponding pivoting devices. Hinged light wings create one Wear-resistant and durable swinging device for the light dar. In particular, if the lights above several hinges pivotable on a neighboring light wing are arranged in the adjustment of the angle of inclination the luminaire wing forces evenly over all hinges added, the individual hinges less loaded and consequently created a long-lasting pivoting device. Furthermore be z. B. compared to an attachment of all lighting wings on hinged hinges less hinges needed.

preferably, are the two outer lights wings independently pivotable, the middle luminaire wing is fixed.

There the illumination of the surrounding environment around the lamp frequently very purposeful or on the environment and its peculiarities It has to be coordinated, it is important that the two outer Luminaire wings independently adjustable are designed.

To the one may depend on the environment to be illuminated be advantageous, the outer lights wings both in the same direction with respect to the plane orientation to tilt the lighting wing, d. H. that the lights wings in parallel or substantially parallel planes lie. On the other hand, it can be the optimal illumination of the environment but also require one light wing to another Direction than the other light wing relative to the to tilt or swivel plane alignment of the lights.

advantageously, the bulbs of the luminaire are light emitting diodes (LED).

LEDs are electronic semiconductor devices, which are characterized by a higher Luminous efficacy compared to conventional incandescent lamps, a high reliability in terms of their lifetime, a high shock and shock resistance, a fast switching and modulability and a current-proportional increase in luminous flux distinguished. For these reasons, LEDs turn out in particular in the lighting of outdoor areas as an advantageous alternative to conventional light bulbs.

This one has the advantage that the power of the bulbs is flexible, depending on the requirements, reliable, long-term cost-effective and out of the Remotely changeable reduce or increase. The data transmission takes place via radio or via Powerline. Powerline is a data transfer via the power grid or other existing lines.

Preferably the control circuit is coupled to a temperature sensor so that the temperature of the light source is determined.

The Lifespan of bulbs will determine their Temperature influences. Thus it is important to know the temperature of the Always monitor bulbs and if necessary override a predetermined threshold, the power of the lighting means to reduce. Conversely, the power of the bulbs then be raised again when the temperature is the predetermined Has fallen below the threshold again. That way, one becomes Temperature-controlled power adjustment of the lamps allows. To the temperature sensor can be anywhere in the lamp body be arranged near the bulbs. As needed Also several temperature sensors at different locations on Luminaire body be provided with the help of those in sub-areas the luminaire body controls the power of the lamps can be.

Preferably is the control circuit with a radio clock and / or with a twilight sensor coupled.

The Regulation of the power of the bulbs can also be additional or alternatively be controlled via a radio clock. On this way it is possible, for example, the Power of the lamps at certain times of the day or night off Cost reasons and / or reduce from an environmental point of view. A twilight sensor allows switching on or switching off the luminaire matched to the surrounding situation to an optimal and at the same time as late as possible or early date.

advantageously, are the luminaire wings of the luminaire with cooling fins provided so that adequate cooling of the bulbs is possible.

As already mentioned, the life of the bulbs depends significantly dependent on the temperature. Thus, it is important the bulbs cool steadily to a consistent good and long-term performance allow. Especially with lights, the air cooling is a cost-effective and at the same time efficient cooling method.

In 1 is an embodiment of an outdoor lamp 100 shown in accordance with the present invention. The outdoor light 100 has a lamp body 10 and a mast bracket 20 on. The extension of the outdoor lamp in the X direction is considered the extension in the longitudinal direction of the outdoor lamp 100 designated. The extension of the outdoor lamp in the Y direction is referred to as the extension in the transverse direction and is the direction along which the lights wings 11 . 12 . 13 (described below) are lined up.

The luminaire body 10 has three transversely arranged side by side lights wings 11 . 12 . 13 on. As in 2 is shown, the three transversely arranged side by side lights wings 11 . 12 . 13 about hinges 15 connected with each other. More specifically, the middle lights wing points 12 on the side surfaces arranged in the longitudinal direction in each case two hinge elements, which together with the at the outer lighting wings 11 . 13 each on the middle lighting wing 12 facing hinged hinge parts facing hinges 15 form.

On the top of the lights 11 . 12 . 13 are a variety of cooling fins 14 arranged. Here are the cooling fins 14 of the middle light wing 12 aligned in the longitudinal direction, while the cooling fins 14 the outer lighting wing 11 . 13 are aligned in a transverse direction.

In the longitudinal direction behind the light wings 11 . 12 . 13 is a cuboid electronics housing 16 arranged, in turn, in the longitudinal direction, a connecting piece 17 followed.

The connection piece 17 has a trapezoidal cross section, wherein the long straight line of the trapezoid is formed as a quarter circle. The connection piece 17 is with the mast bracket 20 connected. More precisely, this is the connector 17 via a screw connection with a guide plate 21 , which is also bent in a quarter circle, and part of the mast holder 20 is connected. In the exemplary embodiment of the outdoor light 100 According to the present invention, the screw connection takes place by means of four screws, which are in the four in the guide plate 21 introduced Einstelllöcher 22 , which are formed as slots, intervene. To the guide plate 21 immediately closes a pipe adapter 23 in the form of a pipe.

The mast holder 20 can be attached to the lamp body in two different ways.

As in 1 can be seen, the mast bracket 20 such on the lamp body 10 be attached that the tube adapter 23 opposite the lamp body 10 is arranged at right angles. Such an arrangement of the tube adapter 23 is called a mast tower. As in 2 shown, the mast bracket 20 but also on the lamp body 10 be attached that the tube adapter 23 with the lamp body 10 is arranged in a line and extending in the longitudinal direction of the outdoor lamp 100 extends. Such an arrangement of the tube adapter 23 is called a mast approach.

The two outer lighting wings 11 . 13 are about the hinges 15 in a longitudinal direction of the outdoor lamp 100 extending axis pivotally between adjacent light wings. Here are the lights wings 11 . 13 in a range of -45 ° to + 45 ° with respect to the flat position of the luminaire vanes, in which all luminaire vanes 11 . 12 . 13 are aligned in a plane, swiveling. In particular, the two outer lighting wings 11 . 13 each within a range of -15 ° to + 30 ° with respect to the level position of the lights 11 . 12 . 13 pivotable.

The pivoting of the lights 11 . 13 can be done independently. As in 3 You can see both light wings 11 . 13 be swung upwards. Of course, a pivoting of both lights wings 11 . 13 down possible. In 4 It is also shown that only one of the outer lighting wings 11 can be swung while the other of the lights 13 remains in the flat position. Of course, it is also possible here that the outer lighting wing 11 remains in the flat position, while the outer lighting wing 13 is pivoted. It is also, as in 5 shown, also possible, the one outer lighting wing 11 to swing upwards, while the other outer lighting wing 13 is pivoted down. Of course it is also possible here, the one light wing 11 to swing down, while the other lights wing 13 is pivoted upwards. Figuratively speaking, the light wings 11 . 12 . 13 a U-shape with a flattened "bow area" ( 3 ), an inverted U-shape with a flattened "bow area", an L-shape ( 4 ) or an S-shape ( 5 ) represent or form.

Furthermore, it is possible to use the lamp body 10 along the curved guide plate 21 to pivot a transverse axis, such as in 3 you can see. Is the mast bracket 20 such on the lamp body 10 attached that pipe adapter 23 forms a mast attachment, the lamp body 10 be pivoted in a range of -5 ° to + 15 °. Conversely, the lamp body 10 be pivoted in a range of -15 ° to + 5 ° when the mast bracket 20 such with the lamp body 10 connected is that the tube adapter 23 forms a mast approach.

In 6 is the luminous intensity distribution of the outdoor lamp 100 the present invention with + 40 ° tilted lights wings 11 . 13 shown. The curve A shows the light intensity distribution of the outdoor lamp 100 of the present invention measured in a transverse direction of the lamp body 10 while the curve B, the light intensity distribution of the outdoor lamp 100 shows measured in a longitudinal direction of the lamp body 10

6 shows that the outdoor lamp 100 according to the present invention characterized in that the outer lights wings 11 . 13 around an axis in the longitudinal direction of the outdoor lamp 100 are arranged pivotally and the entire lamp body 10 also one in the transverse direction of the outdoor lamp 100 arranged axis is pivotable, can achieve a very large area illumination.
