Description

lamp

The invention relates to a telescopic light with at least one telescopic telescopic or spiral element with a radial surface to the longitudinal axis for illuminating construction and accident sites, craft and manufacturing facilities, jobs, sporting events and events, as well as travel and leisure as a floor, hand or Flashlight.

Lights are used in different variations to illuminate large

Indoor and outdoor areas and used to illuminate smaller spaces. Thus, for example, to maximize the illuminated area, the illuminant is mounted as high as possible, for example in the interior of the ceiling or in the outer area of a mast. To make this mobile and the highest possible attachment of the bulb and the resulting

To allow magnification of the illuminated area, preferably telescopic tripods are used. In such telescopic tripods several telescopic elements are interleaved and are extended via a guide mechanism either manually or via a drive relative to each other. This creates a mast, which consists of the telescopic elements and sometimes has a multiple of the original height of the telescoped telescopic stand.

Such a telescopic stand is described for example in the international application WO 2009 / 007284A1. The telescopic stand in this case comprises a plurality of tubular sections, which are pushed into one another. Furthermore, means are provided which serve to extend the inner telescopic segments of the outer telescopic segments. In this particular embodiment, a chain is provided which is attached to the first telescopic segment and attached to the subsequent telescopic elements, so that upon actuation of the chain, the individual elements are pulled apart. Conceivable here is also a manual operation, in which the individual telescopic elements are raised by hand and are provided with corresponding locking means to form a stable column.

CONFIRMATION COPY Furthermore, it is known to use a telescoping technique in lights, as described in GB 1 460 025 A. Here, a street lamp is shown, which consists of essentially two telescopic elements, wherein the lower telescopic element is designed as a protective cover or as a foot. The upper telescopic element is equipped with a conventional light source, such as a light bulb. The telescopic element is completely covered by the Teleskop in the untelected initial position. The telescopic element is additionally protected by the shell of the Teleskop. Furthermore, such a device allows the light source to be easily exchanged, since in the initial position the light source can be easily reached by a person on the ground, this being possible in the telescoped position only with additional aids, such as a ladder.

Furthermore, luminaires are known which consist of several elements which are not arranged telescopically, but rather of stacked elements

consist. The elements used in this case each include a light source. The individual elements are then stacked up to the desired height. The resulting mast thus comprises a plurality of lighting means, which are arranged along the central axis of the mast. Such lights are commonly used in the

Outdoor used for decoration purposes. Such lights are very unstable and thus represent a danger.

Furthermore, there are lights that consist of a luminous body with a

Luminous cover is covered. Such lights can have a variety of forms and are used for advertising and decoration purposes in the outer and inner areas to attract the attention of the beholder. For this reason, the lights are often multi-colored and have a logo. For example, such luminaires are used on rooftops and exterior walls to indicate the seat of a company.

On house surfaces also surface lights can be mounted, which are usually provided with a high density of LEDs on the outer surface. The LEDs have s compared to traditional bulbs, such as light bulbs and gas discharge lights, a rather low luminosity and are therefore only limited use.

In existing lights, conventional bulbs are often replaced by newly developed ^LEDs. The problem, however, with this

Proceeding is that the conventional bulbs have a significantly greater luminosity per area. By replacing this example, by ^LED's, the brightness of the light is thereby reduced considerably. A mere change of lamp and the use of ^LEDs o. Ä., With the same luminous area is therefore not possible for many types of lights. So-called power ^LEDs have a higher luminosity than conventional ^LEDs, however, having to be subjected to large currents. With such a load, not only the luminosity, but also the heat generated increases. This creates very high

Temperatures at the LED, which are not tolerated by normal versions. As far as the LED light is glued, there is a risk that the adhesive melts at high temperatures and the LED light drops from the bracket. As a result, LED ^' s are significantly limited in their luminosity and can only be charged with smaller currents.

The problem of small area is particularly pronounced with hand lamps. In the case of hand lamps, the light source is normally designed to be particularly small. in the

Therefore, a particularly high light intensity is required by the illuminant used. Conventional bulbs are also extremely limited here by LED ^' s replaceable.

In most cases, the light intensity of LED ^{'s is} sufficient only for emergency lighting, which does not require high light intensity. Such lights can be found, for example, in baseboards of aircraft carpets, to indicate if necessary the way to the emergency exit and thus to provide guidance to persons in the dark. The object of the invention is to provide a luminaire, which allows a uniformly large-area illumination or illumination using alternative bulbs.

According to the invention the object is achieved in that at least one telescopic element or a portion of the spiral element formed luminous and the

Peripheral surface of the telescopic or spiral elements is closed in itself. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The luminaire according to the invention consists in contrast to the prior art of extendable telescopic or spiral elements, wherein the peripheral surface of the telescopic or spiral elements is closed in itself and therefore forms a closed outer surface. So far, tripods and telescopic fixings were only intended for attaching lamps or lights. The invention described here forms

Telescope, which is at least partially self-luminous.

The telescopic or spiral elements used are designed so that they are at least partially overlapping. This overlap ensures that a solid, stable assembly is created when the telescopic or spiral elements are pulled apart. This overlap is in the edge region of the individual telescopic or spiral elements. As far as the telescope or

Spiral elements are pushed together, this leads to a complete

Overlapping, so that only the outer peripheral surface of the largest telescopic or spiral element for an observer can be seen. Preferably, it is provided in this case that the peripheral surface of the individual telescopic or spiral elements extend through 360 ° about the longitudinal axis, so that an almost closed sleeve is formed. The closed sleeve offers the largest possible area that can be used as a luminous area.

The great advantage of the invention over the prior art is that a large surface of the lamp can be provided with a luminescent layer. The luminous layer can in this case of an electroluminescent layer or with LED ^'s provided layer. The luminaire can consist of a large number of telescopic elements. With each additional telescopic element, the area provided with a light bulb increases. The area can thus be made very large depending on the application. For example, construction and accident sites, a lot of light is needed to perform any work or rescue. In this case, several luminous telescopic elements can be used.

It is of particular importance that the light for transport can be pushed together particularly compact and in accidents, etc., for example, can be transported by a motor vehicle. The telescopic or collapsible lamp makes it extremely compact form and yet one

to achieve sufficient luminosity, for example, to illuminate an accident site such that the necessary rescue measures can be performed. For supply to the ^LEDs and / or electroluminescent light emitting layer electrical connection elements are provided here. Here is a

Fastener provided for mounting the lamp on a tripod. In a preferred manner, the telescopic element with the largest diameter is attached to the upper end of the stand. In a particularly preferred embodiment, the lamp telescopes automatically when hanging on a tripod. For example, it is conceivable that the telescopic elements are pulled apart only by gravity, or that the spiral element is helically stretched by gravity.

In one embodiment of the invention, it is conceivable to telescope the lamp either by hand or to provide a drive for telescoping the lamp for particularly large and multiple elements.

The lamp can also be designed as a flashlight or flashlight.

Here, the telescoping or collapsibility allows a small congestion, so that the lamp can be easily stored in a bag. If necessary, the lamp is pulled apart to ensure a greater light intensity for lighting. Such a flashlight could, for example, a Replace the floodlight for craftsmen. With limited space and tight installation conditions, the telescopic luminaire can be pulled out only to a part and adapted to the appropriate dimensions. An artisan can, for example, install the luminaire on a hook in small attics or basements and, depending on the necessary intensity, pull the telescope elements apart. For example, this is of particular advantage in heating construction, in electrical installations, in repair shops of vehicles or aircraft and similar applications in which the available space is particularly limited. The fastener can be used here as a handle.

For pulling apart the luminaire according to the invention, it is provided that at least one spiral element is helically stretched. Here, the spiral element forms a wound light strip in the undressed position. When the light is pulled out, the wound light strip creates a three-dimensional helix. The inherent stability of the spiral element forms the necessary spring force to maintain the helical structure.

Furthermore, it is possible to form the telescopic lamp from a plurality of telescoping telescoping telescoping elements. Here are the smaller ones

Telescope elements nested in the next larger elements nested.

In a particularly advantageous manner, it is provided that the telescopic element

is formed multi-layered, wherein at least one guide element is provided with a luminous, cooling, focusing and / or protective layer. The layers can be used either individually or in any combination.

Of particular importance is the guide element, which has at least one guide means for telescoping the lamp, which consists of at least one

Guide spring and a guide groove is formed and self-centering. The guide means are essential to a telescoping of the lamp

enable. In each case, guide means may be provided corresponding to the inner and the outer side of the inner telescopic elements. That's how they attack Guide means each into each other and allow it to telescope the lamp along the guide means. For example, the guide spring in a

Engage guide, which is provided with additional fastening means to lock the guide spring in the guide groove. In addition to the guide means, further aids for telescoping, such as, for example, a carrier mounted in the center of the telescopic elements, a telescoping chain or a cable,

be provided. Such a support may for example be provided with a fastener or with a foot to connect the individual telescopic elements together and, for example, with a hook attached to a wall or ceiling. A trained as a foot element telescopic element makes it possible to set up the telescopic light securely on the ground and the carrier makes it possible to keep the telescopic light in the telescoped position. Here either a telescopic chain or a rope can be used. The Teleskopierkette or the rope can be attached to the upper telescopic element and is guided to the lower end. At the bottom, the rope is used either manually or via a drive to pull the luminaire and the individual elements apart along the guide means. In this case, fastening means may be provided on the guide spring or on the guide groove in order to lock the individual elements in different positions. These may be formed, for example, as a locking pin or as a corresponding hook or taper. Here, the telescoping elements, for example, sensor or electromechanical, are switched so that only the fully telescoped telescopic elements shine. This makes it possible to use the telescopic light in a not completely telescoped state. Furthermore, pressure rollers on the

Abut the outer surface of the telescopic elements and extend in a rotary drive the individual telescopic elements upwards.

Alternatively, the lamp can be telescoped or pushed apart by a spiral spring located inside the lamp. In such a

Embodiment, the coil spring, for example, be slightly conical mounted inside the lamp. The coil spring can not be used for transport

telescoped or extended lamp via a clamping mechanism mus be held together or biased. Removing this clamping mechanism, the coil spring is relaxed and pushes the lamp in an extended position, this end position is held by the spring pressure of the coil spring.

The luminescent layer can be either electro-luminescent or formed sufficiently tightly with LED lights, power ^LEDs, an LED film, duration LED ^'s and / or be provided with LED chips. The great advantage of using such alternative bulbs over conventional bulbs is the high

Efficiency of the LED. This can save up to 90% of the electricity requirement. When using an electroluminescent layer further savings are possible.

Especially the advancements of the LED ^' s makes it possible to change the surface of a

To provide luminous body with an electroluminescent layer. This gives a luminous body, all over its surface and not only selective as ^LEDs light up. In such electroluminescent layers, however, the problem arises as with LED ^'s, namely, that the luminosity is too low at a given surface to enable a large-area illumination. To such

To use illuminated views for illumination and illumination, the body of the lights must be correspondingly large equipped. This possibility is created by the telescopic light, so that even a lighting and illumination of construction and accident sites, craft and manufacturing plants, jobs,

Sporting events or other events is possible.

In order to ensure sufficient brightness of the light, ^the LEDs or the electroluminescent layer with respective streams need to be operated. This produces waste heat, which must be dissipated. For this purpose, a cooling layer is provided, which is in thermal contact at least with the luminescent layer. The cooling layer consists for example of a convection cooling by natural air flow or forced cooling using water or air. Preferably, this cooling layer is provided inside the elements. The cooling layer is For example, as a heat sink, preferably made of metal. Thus, the heat can be delivered either to the outside air flowing through the elements or via a separate water cooling system within the telescopic elements. Such a cooling layer is of particular importance when at high currents the

Temperature can rise dramatically and u. U. damage to the luminescent layer should be avoided.

Furthermore, it is also possible by enlarging the area the missing

Brightness per unit area to be compensated by an enlarged area. This reduces at the same time the effort required to cool the lamp.

The development of ^LEDs or electroluminescent layers also improves the illustrated telescoping light here and increases its efficiency in the area of application.

For convection within the elements, for example, contribute to a setting gap at the foot of the lamp. Through this setting gap creates an opening through which the air can pass from bottom to top through the entire lamp. By the

air flowing through the lamp is cooled. The heat generated in the luminescent layer is dissipated by this and the luminescent layer can be operated accordingly with higher currents, which leads to an increase in light intensity and better illumination.

The telescopic elements can assume essentially any shape. In a particularly advantageous manner triangular, polygonal and round cross sections are provided. Depending on the field of application of the telescopic luminaire, the cross section can be adjusted. For example, a round cross section is particularly suitable for a handbag lamp.

In a further advantageous embodiment, the luminaire can be provided with a focusing layer, which comprises spaced-apart focusing elements, wherein between each two focusing elements an LED on the underlying Luminescent layer is arranged. Hereby the lamp can be used as a diffuser or floodlight. Thus, with appropriate alignment of the focusing layer on the luminescent layer, a scattered light can be generated. The focusing layer with the

Focusing elements can also be mounted rotatably relative to the luminescent layer. Thus, it is possible that the focusing elements are rotated so that they become available ^LEDs to cover. In this position, the light of the LED ^{'s is} focused and one receives directed light. This may be important, for example, if the lights should not be used for large-area illumination, but for selective illumination, such as in a flashlight or in a larger configuration by a so-called spot light. The focusing layer or the focusing elements can be made of glass or glass-like plastic, such as polycarbonate or acrylic. In general, any material is conceivable which is also used in the manufacture of lenses. In particular, when using such a focusing layer, it is advantageous if in addition an outer protective layer is used. This can for example consist of a particularly tempered glass or plastic. A further embodiment possibility is to attach the focusing elements inwards in the direction of the LED ^'s . This creates a smooth outer layer that is less susceptible to damage.

An energy saving option is to design the lamp such that the outermost telescopic element always and the inner telescopic elements shine only in the telescoped position after switching. This is particularly advantageous if the luminaire is often used in a not or not fully telescoped position.

Here you can disconnect the inner telescopic elements of the power supply and illuminate only visible to the outside telescopic elements. This is possible, for example, via the fastening means provided in the guide layer. When locking this, the corresponding telescopic element or the luminescent layer is supplied with voltage.

The connecting elements can be designed, for example, as a sliding contact from element to element, wherein a switch can be switched on and off. exists. Moreover, it is conceivable that the connection elements of the individual telescopic elements are connected to an external power supply or a battery integrated in the lamp.

Furthermore, it is conceivable to produce a directed light beam on the

Exterior surface of the telescopic lamp to provide a reflector, either single telescopic elements or the entire lamp via at least one

Part circumference covered. For this purpose, a roller can be provided to wind the reflector. By such a reflector, the light is not emitted over the entire circumference, but the entire light intensity emitted by the not covered by the reflector surface. Thus, if necessary, the light intensity can be increased in a preselected direction. In addition, it is possible to shield light in a certain direction. This could be the case, for example

Use as a flashlight to not blind the user. In lights to illuminate accident or construction sites, this could serve to not blind the drivers of arriving cars unnecessarily.

The invention will be explained in more detail below with reference to FIGS.

Figure 1 shows a fully telescoped lamp 1, in a sketch-like representation consisting of five telescopic elements 2 and a fan 3. The telescopic elements 2 are each provided with locking means which hold the telescopic elements 2 in the telescoped position. The locking means are part of the guide elements. The guide elements also have guide means, which may be designed in particular as a guide groove and guide spring. The

Guide groove and guide spring are self-centering and corresponding to the inner 5 and the outer side 6 of the inner telescopic elements 2 are provided. The guide means engage each other and thus make it possible to telescope the lamp 1 along the guide means. In addition, as a tool for telescoping, for example, a carrier, a Teleskopierkette or a rope

be provided. The fan 3 is used for convection cooling of the telescopic elements 2. The fan 3 generates a draft within the lamp 1, through which the

Telescopic elements 2 are cooled to dissipate the heat generated by the operation of the lamp 1. The fan 3 is to be regarded as optional, since a natural Luftkonvektion occurs when using the lamp 1. Furthermore, the fan 3 can be perceived as disturbing when the lamp 1 is used as a flashlight or flashlight, so that can be dispensed with the fan 3 in this case, especially since in a smaller version of the lamp 1, the resulting heat is relatively low and no requires additional convection cooling.

Figure 2 shows a plan view of the lamp 1 with a plurality of telescopic elements 2 and a fan 3. The fan 3 is in this embodiment in the smallest Telescopic element 2 integrated. The telescopic elements 2 are designed so that they simply slide into each other, namely the smaller in the next larger

Telescopic element 2. The locking means in conjunction with the guide groove and the guide spring make it possible to telescope the telescopic elements 2 relative to each other and to allow the use of the lamp 1. The telescopic elements 2 are here exemplified cylindrically and have a round cross-section. However, any cross section is conceivable, for example, a three or polygonal shape.

Figure 3 shows a perspective view of a completely pushed together lamp 1, consisting of several telescopic elements 2, a fan 3 and a battery 7. In this embodiment, the fan 3 is provided in the smallest telescopic element 2. However, it is also conceivable to attach a fan 3 in the largest telescopic element 2 at the lower end. Prerequisite is

However, that the fan 3 has a flat design. To operate the lamp 1 is also possible to use a battery 7, which the lamp 1 with

sufficient voltage supplied. This is especially advantageous in the case of small and extremely mobile luminaires 1. For larger lights 1, it is still quite conceivable to provide a battery, but this becomes too large with increasing luminous area of the telescopic elements 2. From a certain size it makes sense to

Replace battery 7 with an external power supply.

FIG. 4 shows a plan view of an alternative luminaire 1, consisting of one

Spiral element 2 'and a fan 3. The spiral element 2' is wound in this embodiment and pulled apart in Figure 4, but it has enough inherent stability to keep the lamp 1 in a helical shape. Here is one

sufficient spring tension of the spiral element 2 'necessary. This can be additionally ensured by a stiffening of the spiral element 2 'or

Spiral element 2 'has sufficient bias to the outside.

Figure 5 shows in a perspective view of the fully telescoped lamp 1 of Figure 4, consisting of a helically pulled apart spiral element 2 '. The lamp 1 with a helically wound spiral element 2 'consists in the telescoped position substantially of only one element. The overall height of the helical lamp 1 is limited by the total length of the element.

Figure 6 shows a perspective view of the spiral completely wound lamp 1 with a spiral element 2 '. The lamp 1 is to be transported by the winding of the spiral element 2 with particularly small dimensions.

FIG. 7 shows in a perspective view a completely telescoped luminaire 1 with a foot element 8. The completely telescoped luminaire 1 also has a fan 3 and a battery 7. These are each, as before

described, provided for forced convection cooling and to operate the lamp 1. The foot element 8 is fastened to the lowest telescopic element 2. The foot element 8 has actuating gaps 4, through which air can flow into the interior of the lamp 1. In conjunction with the fan 3 thus creates a suction through the lamp 1, which serves to cool the telescopic elements 2. In particular, with a sufficient height of the lamp 1, a fan 3 is not absolutely necessary to produce a sufficient air flow within the lamp 1. This can cool the lamp 1 sufficiently by the natural convection.

FIGS. 8.1 and 8.2 show a completely telescoped luminaire 1 with a detailed view of the layer structure of the telescopic element 2. The telescope elements 2 are constructed of several layers, the innermost layer 11 representing a cooling layer onto which a luminous layer 10, in this embodiment with LED ^' s 9, and finally a protective layer 12 follows. The cooling layer 11 is in thermal contact with the luminescent layer 10, in order to allow a sufficient dissipation of the heat generated by the LED ^'s 9. Instead of the protective layer 12, a

Focusing be provided. The focusing layer can with individual

Focussing elements to be equipped, which are arranged between each two LED ^' s 9 of the luminescent layer 10. The focusing layer is rotatably mounted on the luminescent layer 10. If you now turn the focusing elements over the LED ^' s 9, then you can transform the lamp 1 from a diffuser lamp to a floodlight with aligned light field.

FIGS. 9.1 and 9.2 show a completely telescoped luminaire 1 with a detailed view of the layer structure of the telescope element 2, an electroluminescent luminous layer 10 'being used. The essential structure of the telescopic member 2 is similar, as with the use of ^LED's 9 11 with a cooling layer The electroluminescent phosphor layer 10 'is in thermal contact with the

Cooling layer 11. The luminescent layer 10 'is formed completely electroluminescent and does not light selectively, but over the entire surface. The

Focusing elements can be formed like a lens to produce a floodlight.

Figure 10 shows the use of the lamp 1 with telescopic elements 2 as a flashlight or flashlight. A person 18 can hold the lamp 1 comfortably in his hand and this to illuminate small rooms or for

Use lighting the way.

FIG. 11 shows the use of the luminaire 1 with telescopic elements 2 on a vehicle 19. This is especially suitable for rescue vehicles, since the telescopic luminaire 1 can be carried along with a small stowage volume and can be completely telescoped if required. A fully telescoped lamp 1 allows rescue operations to be carried out even when darkness sets in.

FIG. 12 shows the completely telescoped luminaire 1 using a stand 21. The stand 21 is provided with a fastening element 20 in order to receive the telescopic luminaire 1 on the stand 21. Preferably, in this case the lamp 1 is mounted on the stand such that the telescopic element 2 is located with the largest diameter at the upper end. As a result, the largest in area and thus brightest telescopic element 2 is provided with the longest range, so that the lamp 1 can be used effectively. FIG. 13 shows a telescopic luminaire 1 on a mobile unit 22. The mobile unit 22 also makes it possible to use a relatively large luminaire 1 without problems on the move. As a mobile unit 22, for example, a trailer, which includes, for example, a generator or a battery for operating the lamp, for mounting on motor vehicles conceivable. Here, preferably, similar to the tripod 21, the largest telescopic element attached to the upper end of the lamp to effectively use the lamp 1 to illuminate a large area possible.

FIG. 14 shows a luminaire 1, consisting of a luminous sight 10, provided with LED ^'s 9, a cooling layer 11 and a focusing layer 33, consisting of

Focusing elements 34 and diffuser elements 35. The cooling layer 11 serves, as already described, for cooling the lamp and for dissipating the heat generated by the LED ^'s 9 during operation of the lamp 1. The focusing layer 33 serves to the lamp 1 of a diffuser lamp in a floodlight with directional light field too

transform. For this purpose, the focusing layer 33 is rotatably mounted with respect to the luminescent layer 10 on the lamp 1. The focusing elements 34 are mounted on the focusing layer 33 in such a way that in each case one LED 9 between two

Focusing 34 is located. Between the diffuser elements 35 each have a focusing element 34 is provided. The embodiment shown here is greatly simplified with respect to the number of ^LED's 9, the focusing elements 34 and the diffuser elements 35 for clarity. In the application, a significantly higher density of the LED ^' s 9 is necessary to obtain a sufficient light intensity. With a higher density of LED ^' s 9, the density and number of LEDs increases accordingly

Focusing elements 34 and the diffuser elements 35th

FIG. 15 shows the light field of the luminaire 1 shown in FIG. 14. The luminaire 1 comprises a cooling layer 11, a luminous layer 10, LED ^'s 9, a focusing layer 33, focusing elements 34 and diffuser elements 35. In FIG

Position of the focusing elements 34, or the diffuser elements 35, the lamp 1 is provided as a diffuser light. The diffuser lamp has radially formed ISO lux lines 40. FIG. 16 shows the luminaire 1 described in FIG. 14 with a cooling layer 11, a luminous layer 10 with LED ^'s 9, a focusing layer 33 with focusing elements 34 and diffuser elements 35. The luminaire 1 is in the focusing position in the illustrated form. In this position, the focusing elements 34 are directly above the LED ^'s 9. Due to the special design of the focusing elements 34 thereby creates flood light with a directed light field. In the exemplary embodiment shown here, the design of the focusing elements 34 forms a light field with ISO lux lines 40, which essentially form a multi-leaflet sheet. This creates a directional light field in four directions. However, this can be expanded in any desired directions with appropriate design of the focusing elements 34.

Figure 17 shows the lamp 1 provided with a reflector 45. For this purpose is a

Rotary axis 46 provided in the center of the lamp. This is connected to the attachment 47 with the reflector 45. The reflector can be rotated radially symmetrically about the lamp 1 in the desired manner. The light field 50 of the lamp 1 is formed according to the position of the reflector 45 cone-shaped in a certain direction. The reflector 45 may be formed radially symmetrical, parabolic or planar. The reflector 45 can also be varied in its width and can cover an arbitrarily large part of the circumference of the lamp 1. This results in a directional light field in a more or less limited area. This can range from 360 ° for a fully collapsed or rolled reflector 45 to a few degrees for a fully unfolded or rolled reflector 45.
