Description

The invention relates to a lighting device for the large-area surface inspection of components, with a reflector and a lamp, wherein the reflector reflects light emitted by the lamp, wherein the reflector is arranged in an arc around the luminaire, wherein the reflector has a central luminous area and a laterally adjoining anti-glare area, wherein the luminous area allows a proper illumination of a component to be inspected and the anti-glare area prevents direct light emission from the luminaire to the user.

The DE 28 51 828 A1 relates to a reflector for generating a uniform radiation distribution with a rod-shaped lamp. The reflector is parabolic. By arranging two lamps with associated reflector, the lamp intensity is increased.

The US Pat. No. 3,829,677 shows a reflector for a fluorescent tube, which is arranged parabolically around the fluorescent tube around. At the apex of the parabolic shape, a lamella is arranged along the longitudinal axis.

The US 8 523 381 B1 relates to a system, a method and the use of a revolver socket for a fluorescent tube. The system has a reflector with lamellae on the fluorescent tube. The lamellae preferably have recesses through which the heat emitted by the fluorescent tube can be dissipated.

The DE 85 19 706 U1 relates to a counter-radiator lamp with a main reflector, a fluorescent lamp and arranged below the fluorescent lamp counter-reflector. The main reflector is made up of two concave surfaces that bulge over the fluorescent lamp.

The US 5 613 761 A discloses a lightweight plastic reflector. The reflector has a cover layer which has a plurality of elongated depressions arranged close to each other. On the surface of the cover layer, a mirrored layer is adhered.

The DE 44 43 741 A1 relates to a luminaire for elongated luminous means, wherein the respective luminous means is arranged in the interior of a flat trough-shaped housing. The lamp is associated with a Abblendeinheit, which consists of a plurality of mutually spaced grid surfaces of translucent material.

From the US 2009/0027877 A1 a lighting device is known. In this eint can be provided over several fluorescent tubes extending reflector screen, which has a kind of beads between the individual fluorescent tubes, wherein the beads each hinder visual contact between two fluorescent tubes. This lighting device is designed to emit the light directly, with the interposition of a plate-like diffuser body. Consequently, the illumination device does not have any generic antiglare areas, since light propagation is provided along the entire length of the diffuser body.

The US 2011/0043132 A1 relates to a lighting device. In the lighting device, a light source unit is arranged between two arcuately curved reflectors exactly at the intersection. The light source unit has two light-emitting diodes, which illuminate one of the reflectors in opposite directions in each case. Consequently, in this lighting device not a reflector arcuately arranged around a lamp around, but the lights are rather fixed at the intersection of two juxtaposed reflectors. This arrangement also results in that a region of low light intensity arises in the mounting region of the light source unit. The lighting device also has no subdivision into lighting areas and glare protection areas.

The US 5,613,761 discloses a reflector for a lighting device. In an embodiment in which two reflectors directly connect each other, all the reflectors are each formed symmetrically. This means that each reflector has either no antiglare area or symmetrically on both sides each have a glare protection area.

The US 4,602,448 relates to a panel element for a lighting device. The panel element has a plurality of illuminants, wherein a reflector is arranged in an arc around a respective illuminant. The panel element or the lighting device does not have an anti-glare area, since the light propagation over the entire length of a panel should take place directly only with the interposition of a transparent lens.

The US 4,796,168 discloses a lighting arrangement for fluorescent lamps. It can be created multi-part reflectors, however, wherein the reflectors forming individual parts must be secured together by means of a holding device. Consequently, in each case two reflectors are coupled in their intersection or connection point with a holding device which projects into the reflector space, so that there is no optimal Illumination can take place. However, this plays no role in this lighting device, since it is designed for a direct propagation of light, ie even without reflection on the reflector. Consequently, even this lighting device is a subdivision into lighting areas and glare protection areas foreign, as a direct light emission over the entire length of the lighting device takes place.

The US 5,192,129 also relates to a lighting device with symmetrically constructed reflector screens. Consequently, the individual reflector screens have either no glare protection area or else two symmetrical glare protection areas. On glare protection areas, however, it does not matter anyway with this lighting device, since this is designed for direct light emission.

A generic lighting device is from the DE 20 2011 107 964 U1 known. These are devices that serve the surface inspection of components. For example, in the automotive industry body parts are tested by such a lighting device in terms of their shape. Deviations from the desired shape can be detected by using a generic lighting device by a shadow on the body part.

A generic lighting device is characterized in that the light emitted by the light does not radiate light directly and diffusely on the component to be inspected, but with interposition of the reflector. For this purpose, the reflector is arranged arcuately around the lamp. The reflector is arranged in particular spaced from the lamp. Arcuate means in particular semicircular or parabolic. The light emitted by the light hits the reflector and is reflected from there in the direction of the component to be inspected. It can thereby be ensured that the light radiated by the lighting device as intended runs in parallel beams and strikes the component to be inspected exclusively indirectly from the lamp by interposing the reflector.

A conventional lighting device 101 is exemplary in 6 shown. This has a reflector 102 and a light 103 , The reflector 102 is parabolic and consists of individual lamellae. The lamp 103 includes a light bulb 115 and a shading device 116 ,

The shading device 116 serves to direct light emission in the intended lighting direction 106 to prevent. That of the bulb 115 emitted light should rather only indirectly by reflection at the reflector 102 in the intended lighting direction 106 be radiated.

The reflector 102 has a light area 105 and laterally adjoining glare protection areas 104 on. While the lighting area central to the bulb 103 is formed around, are the glare protection areas 104 from the light 103 spaced. The glare protection areas 104 are in the edge areas of the reflector 102 educated.

The light area 105 arises as a function of the arrangement of the lamp 115 , the shading device 116 and the reflector 102 relative to each other. The light area 105 is limited by the beam angle of the lamp 103 , in which the light intensity for a proper illumination of the component is just high enough. This angle is in the 6 shown with a dashed line. It is now necessary, the reflector beyond the light area even further with the glare protection area 104 train. The glare protection area 104 namely serves to direct radiation of light to a lighting device 101 prevent the user from using it. For this the reflector must 102 in the glare protection area 104 be formed such that an imaginary tangent to the light source 115 which passes through a free edge of the Abschatteeinrichtung 116 runs on the reflector 102 meets and thus no direct visual contact with the user is possible. This imaginary tangent is in the 6 shown with a dash-dotted line. In a generic lighting device, the combination of shading device on the one hand and reflector on the other hand ensures that only reflected light on the reflector leaves the lighting device in the intended lighting direction.

Although the the DE 20 2011 107 964 U1 Although disclosed lighting device has basically proven, there is still room for improvement. Namely, the surfaces of particularly large-area components to be inspected, which requires a correspondingly wide luminous range.

The previous experiments provide that the components of the lighting device are dimensioned correspondingly larger, so that the lighting device is designed to be correspondingly larger overall. From the DE 10 2008 003 215 A1 In addition, a reflector is known whose curvature is variably adjustable. However, this has not proven in practice, since he is expensive to manufacture on the one hand and on the other hand his attitude is very difficult, which brings a considerable time and expense.

Based on the above-described prior art, it is thus the object of the present invention to improve a generic lighting device to the effect that the surface inspection of particularly large-area components is simple, flexible and inexpensive.

To solve the invention proposes a lighting device with the features of claim 1.

Furthermore, a reflector-lamp pair with the features of claim 17 and a light device system with the features of claim 18 is proposed to solve the problem.

According to the invention, it is provided that two pairs of reflector and luminaire are combined with one another. In contrast to the known from the prior art lighting devices, however, not only two of these known lighting devices are arranged side by side, but it is dispensed with two juxtaposed reflectors on the otherwise abutting anti-glare areas. In other words, two known from the prior art lighting devices are taken and separated in each case one of the two anti-glare areas. With the sides trimmed around the anti-glare area, the two reflectors are placed against each other. Thus, the luminous area of the one reflector goes into the luminous area of the other reflector. The result is an uninterrupted luminous area, which is twice as wide as the luminous area of only one reflector. The two reflectors merge into each other without glare protection.

A reflector of a lighting device according to the invention is asymmetrical. An imaginary vertical connects the luminaire with the vertex of the reflector. With respect to this vertical, the reflector is asymmetrical. While the prior art proposes a symmetrical parabola or a symmetrical semicircle, a reflector according to the invention is cut off at one side. That is, the legs of a parabola, for example, according to the invention have a different length.

With respect to the height of a device according to the invention, the respective outermost limbs of a row of reflectors protrude lower than the mutually facing limbs of adjacent reflectors. With respect to the width of a device according to the invention, the outermost legs of a row of reflectors are wider than the legs of adjacent reflectors.

According to the invention, in the case of reflectors arranged next to one another, a part of the reflector which effects an antiglare area is dispensed with. This is possible because a user usually does not reside directly under a lighting device according to the invention, but outside of it. Under the lighting device only the components to be inspected are handled. The invention is therefore also based on the finding that a glare protection area is dispensable for reflectors arranged next to one another.

The invention thus provides, with surprisingly simple means, a lighting device which has an uninterrupted and comparatively wide luminous range. For example, the individual reflectors do not have to be adapted in terms of their height, so that the same installation space as in a conventional lighting device is sufficient in the height direction. In addition, the lamps surprisingly do not have to be formed in a special way, but rather conventional lights can be used. With the solution according to the invention thus eliminates the well-known from the prior art upscaling of the components of the lighting device or according to the DE 10 2008 003 215 A1 provided cost-intensive and cumbersome concept of adjustability of the reflector screen. The lighting device according to the invention is thus in its construction very simple and therefore also quite cheap to produce. In addition, flexible lighting devices can be created, which have a different and individually selectable lighting area.

The inventive concept can be realized in many ways. For example, two or more reflector-light pairs arranged side by side can form a component which can be handled as a unit. Thus, a one-level lighting device is virtually achieved, which has the same height compared to the prior art twice as wide lighting area. But it can also be provided that each reflector-light-pair as such forms a unit manageable as a unit. To produce an entire lighting device then the individual reflector lamp pairs can be assembled arbitrarily. However, it is also possible for a plurality of reflector-light pairs, which are arranged side by side, to be designed as unit-manageable components, which in turn can be interconnected to even larger lighting devices. It is crucial that in a series of multiple reflector-light pairs always the luminous area of a reflector connects to the luminous area of the other reflector. Thus, arranged between two reflectors reflectors must be formed on both sides without a glare protection area. so you are as known from the prior art symmetrically formed, but without a glare protection area. However, in order to avoid dazzling the user, the two outer reflectors of a row of reflector-lamp pairs must each have an antiglare area on the side facing outwards.

In particular, it is possible to provide a multiplicity of reflector-light pairs of different design, which can be used in a lighting device according to the invention. These differently shaped pairs can be combined to form a lighting device according to the modular principle. For this purpose, a standardized connection means may be provided on the reflector-lamp pairs, which always allows a connection with a differently designed reflector lamp pair, regardless of the specific design of the reflector.

It is thus created a particularly simple and flexible handling lamp system, in which depending on the size of the surface of the component to be inspected, a lighting device can be created with a suitably large illuminated area.

According to an advantageous embodiment of the invention, the reflector and the lamp of a reflector-lamp-pair between two opposite side walls are added. The side walls may be congruent and / or parallel to each other. The reflector may have the shape of a longitudinally cut sleeve. The lamp may be rod-shaped or have a rod-shaped light source. A supply line of the luminaire can be led outside on one of the side walls. The electrical connections for a generic lighting device are usually provided above the reflector on the ceiling of a room. From there they must be led to the light. This is arranged from the ceiling of the room under the reflector. The lead out of the supply line from the side wall and the length of the supply line outside on the side wall has the advantage that the supply line on the one hand does not hinder the propagation of light within the lighting device and on the other hand is not exposed to the possibly occurring high temperatures inside the lighting device.

The supply line of the luminaire can, in particular above the reflector, be passed through the side wall again and be coupled with an electronic unit arranged between the two side walls. The electronics may be a ballast for the operation of the lamp and / or the like. The connection between the lamp on the one hand and the electronics on the other hand can thus be done without any obstruction of the lighting device, in particular the luminous area.

The electronics can be arranged in a connecting the two side walls together strut. There she is taken especially safe and protected. The strut can be designed as a cross-sectionally U-shaped profile element. In the interior of the U-shaped profile, the electronics can be inserted, for example glued, screwed or the like. The electronics can be integrated in a particularly simple manner in the lighting device.

According to an advantageous embodiment of the invention, in each case a corner of a side wall and a corner of the other side wall is connected to each other by a strut. This applies in particular to the corners of the side wall, in the area of which the glare protection area of the reflector protrudes. By the strut a kind of protection is created, which avoids unwanted contact and damage to the reflector. Such a touch can happen, for example, when handling a component below the lighting device. The user wants to rotate the component and pushes from below against the reflector. Damage to the reflector could be the result. By the strut according to this development, the component is limited in its path of movement. The reflector is not touched. The strut may be formed, for example, as a cross-sectionally L-shaped profile element. The two legs of the Ls may be parallel to a side edge and a bottom edge of the side wall. By such a profile element, a particularly large-scale protection can be achieved, wherein comparatively little space is required in the interior of the lighting device. The advantage of such a strut is also that the connection stiffness of the entire lighting device can be increased.

The reflector may be formed of a plurality of elongated blades, as in the DE 20 2011 107 964 U1 is described. The lamellae can themselves be provided with a reflective coating. According to an advantageous embodiment of the invention, it is proposed that the coating is interchangeably arranged on the lamella. The coating may be provided by a coating element. It is possible to provide coatings or coating elements with different properties. Coatings may differ in particular with regard to their reflection properties. Depending on the desired properties, one or the other coating on the Slat arranged. The lamella can thus serve as a kind of basic body, which is always the same regardless of the desired reflection property. This basic body is provided with a desired coating element. This coating can also be replaced at any time at will. There may be provided a plurality of coating elements with different reflective properties, which are all interchangeable with the lamellae interchangeable according to the modular principle. Thus, a particularly flexible and easy to handle reflector is created.

The coating of the lamella can be subdivided into different regions in the longitudinal direction with regard to the reflection properties. It may, for example, be two coatings which are to be handled independently of one another and which are arranged in respectively different regions of the lamella. Thereby, a lighting device can be achieved, in which different test zones can be formed.

The coating can be pushed onto the lamella on one or both sides. The lamella may have a longitudinal groove. In this, the coating can be used and then postponed. This makes the coating particularly easy to handle and replace. However, the lamella and the coating element can also be designed as profile elements which are substantially U-shaped in cross-section. These can be pushed onto each other. In the pushed together state, they grab each other.

The lamp has a lamp and a Abschatteeinrichtung. The shading device and the lamp can be designed as a unit manageable component. It may, for example, be a fluorescent tube with an integrated reflector. The lighting means may be rod-shaped, for example in the form of lined-up LEDs or the like. The Abschatteeinrichtung may be formed in cross-section U-shaped. The shading device can partially absorb the light source. The shading device serves to prevent direct radiation of light from the lighting device out.

The Abschatteeinrichtung may be internally provided with a reflective material. For this purpose, on the one hand, the efficiency is increased, since the luminous efficacy can be increased accordingly. In addition, a kind of heat accumulation in the area of the illuminant is created, whereby the illuminant can be kept in a temperature range with optimum efficiency.

According to an advantageous embodiment of the invention, a plurality of juxtaposed reflector-lamp pairs is provided, wherein the reflectors of the individual reflector-lamp pairs are formed differently in terms of their reflection properties. In this way, a kind of test lane can be created, wherein the components to be checked pass successively the reflector-lamp pairs with different reflection properties. As a result, for example, matt area on the one hand and high-gloss areas on the other hand, the surface of a component can be checked separately from each other. Additionally or alternatively it can also be provided that the reflectors are subdivided transversely to the direction of the juxtaposition into areas with different reflection properties. A user of a lighting device according to the invention can pass the component to be tested, for example, transversely to the direction of the juxtaposition to a second user who then checks the component using the different reflection properties. This makes it possible to set up a wide variety of test lanes particularly flexibly, which can be individually adapted to the needs and / or circumstances at the respective place of use.
