Description

  • The The invention relates to a lighting module, in particular for lighting a cabin of an aircraft in which the for lighting provided light sources are represented by light emitting diodes.
  • Currently wins the use of light emitting diodes in lighting systems of all kinds, especially for Interior lighting, increasingly important. The reasons for the increased commercial Use of light-emitting diodes are inter alia in comparison with earlier generations of light emitting diodes improved light output, in conjunction with their Advantages over classic light bulbs. In light emitting diodes, radiation applications are now sufficient achieved high luminance. At the same time, light-emitting diodes are emerging through a high energy efficiency, safety and durability. Furthermore, light-emitting diodes are available in a number of different colors disposal and radiate almost monochrome, in other words in a narrow Spectral range. In contrast, must for the generation of monochromatic light with glow lamps much of the Spectrum are absorbed by corresponding color filters, which incurs a corresponding loss of energy. This is the possibility given to be driven by suitable combinations separately colored differently Light-emitting diodes infinitely colored mixed light energy-efficient, with to generate little effort and space saving. In contrast to Filter systems are space-intensive and mechanically complex.
  • Interior lighting systems with light emitting diodes, especially for the lighting of a cabin in an aircraft, are already coming for use. In the current state of the art are such lighting systems configured such that for the purpose of light mixing in front of the LEDs a an observer facing the scatter plate is mounted. In the application Such a lighting system may disadvantageously to an inhomogeneous illumination up to a glare of a Observers lead. However, in particular, because the cabin of an aircraft is an area in which the dark adaptation of the eye is not impaired may, a detrimental lighting can be safety relevant. Also, it may happen that the observer depending on the direction of observation can still recognize individual colors (rainbow effect).
  • task The invention is an illumination module with a number of Specify light emitting diodes, in which the most homogeneous possible illumination an interior or part of the interior, in particular one Cabin of an aircraft while avoiding dazzling effects is achieved.
  • The Task is for a lighting module having a number of light-emitting diodes thereby solved that it is provided with an aperture and a reflector that the light-emitting diodes in one of a given observation area through the aperture concealed area are localized, and that the reflector so is arranged and configured that emitted by the light emitting diodes Light into the intended illumination area, i. the one to be illuminated Area leads. This lighting concept will also be referred to as "Hidden Source "concept called.
  • By the covered arrangement of the or each LED becomes a dazzling effect for the observer avoided by direct light. An observer is through the aperture the direct view of the LEDs denied. Through the reflector the light emitted by the or each light emitting diode arrives indirect way to the observer. By extending the light path opposite one previously known arrangement, wherein the light-emitting diode behind a spreader plate is arranged, the light mixture of individual light-emitting diodes is improved, which leads to a homogeneous illumination. In particular, is through this arrangement also improves the color mixing of the light achieved different colored LEDs, so that the aforementioned rainbow effect is avoided.
  • The Lighting module is advantageously for each application with provided a suitable shape.
  • Especially for the Use indoors with an excellent longitudinal direction, like a cabin of an aircraft, is the shape of the lighting module advantageously by a longitudinal axis along which it has a substantially uniform cross-section. For example, lighting modules designed as line lights, their lighting areas essentially by their length are defined in this category.
  • Further preferred embodiments of the invention are concerned with the way as the reflector of the lighting module for the purpose of indoor lighting interacts with the light emitted by the light sources.
  • According to the above explanations, inhomogeneities of the illumination and direct irradiations should be avoided, in particular for the interior lighting of a cabin of an aircraft, and conversely the most uniform, indirect illumination should be achieved. This property will advantageously supported by the fact that the reflector is designed for a particular broadband diffuse reflection. Conveniently, this is achieved by manufacturing the reflector of suitable material, such as a light plastic, which is optionally provided with an additional coating. It is also conceivable to form the reflector as a sheet-metal shaped part, which is coated with a suitable, diffusely reflecting film.
  • In In a preferred embodiment, the light sources acting as light sources Light-emitting diodes on a side surface arranged the module, which is substantially perpendicular to the Aperture of the module is aligned. By this configuration results Overall, a compact design. In particular, there is a at least one-sided rectangular geometry, as for installation in existing installation spaces of vehicles and in particular of aircraft, e.g. Behind Ceiling or side walls, is advantageous.
  • Furthermore are expediently the light emitting diodes arranged linearly in a row, for example parallel to the longitudinal direction the lighting module, in particular in an embodiment of the Module as a line light. This embodiment is particularly suitable for the Radiation of elongated uniform spaces, as they are, for example to find in an airplane. Further, suitably, a plurality of light-emitting diodes each grouped into a group, these groups in a corresponding arrangement. For example, it will in a corresponding execution the lighting module with identical LEDs the entire light intensity elevated.
  • Currently standing Light emitting diodes available in a number of different colors. In an advantageous embodiment of the lighting module comes this to apply, by following the above principle, groups of Light-emitting diodes are formed, each having different colored LEDs include. By an electronically separate control and intensity variation The light-emitting diodes of different color is thus infinitely mixed-color light Generable, without the need of using filter systems. To mixtures can the basic colors red, green and blue are used. Due to the rather monochromatic radiation characteristic However, mixed white light is not considered natural. It is therefore recommended, in addition to the three basic colors of each group a white light diode to add. It may also be provided for the purpose of generating intensive oranges to use an amber colored LED.
  • Preferably the lighting module is geometrically shaped so that the distances of the differently colored LEDs to each other within the LED groups as possible small opposite the light paths within the lighting module is, thereby the color mixing behavior is optimized.
  • to Achievement of a homogeneous radiation characteristic in a defined Illumination area is in addition to the reflection properties of the reflector whose geometry is relevant. To avoid inhomogeneities is the reflector preferably provided with a smooth curvature. preferably, is the reflector opposite The light sources concave shaped, so that the lighting is optimal is homogeneous and focusable, especially with regard to an application as a line light. In addition, by a concave shape of the average distance between the light sources and the reflecting surface increases, thereby when using adjacent differently colored LEDs As light sources, the light mixture is improved.
  • Optionally, is the light exit area of the lighting module in front of the reflector covered by a light-permeable cover, which in particular for Protection of the interior of the lighting module is used. The light-permeable cover can For example, designed as a transparent or diffuse plate be. The latter has the additional Advantage that this further improves the effect of the light mixture becomes.
  • advantageously, is a lighting module designed to be made up of individual ones Lighting modules in the longitudinal direction is composed. In particular, this is for use as cabin lighting relevant. Such a modular construction is especially for transport advantageous because the individual modules smaller dimensions than the total module exhibit. Also allows a modular design, the adaptation of the overall system to various installation geometries, without the individual modules essential amended Need to become, what about an adaptation of the entire system to any changed installation geometry is extremely cost-effective.
  • embodiments The invention will be explained below with reference to a drawing. there demonstrate
  • 1 a lighting module in cross section to the longitudinal direction in a schematic representation, and
  • 2 another lighting module in a perspective view.
  • The exemplary embodiments each show a Lighting module, as intended for installation in the cabin of an aircraft.
  • In 1 is a lighting module 1 initially shown schematically in cross section to a longitudinal direction. The lighting module 1 is through a parabolically curved reflector 2 through a panel 3 and by a side surface 4 educated. On the side surface 4 is a number of light-emitting diodes 5 arranged linearly along the longitudinal direction. In the cross section shown is of these LEDs only a light emitting diode 5 visible, noticeable. The light exit opening through which that of the or each light emitting diode 5 emitted and from the reflector 2 deflected light escapes to the outside, is through a light-permeable cover 6 protected from a transparent plastic.
  • The reflector 2 is formed as a sheet metal part, on the surface of which a diffusely scattering plastic film is laminated. That of the or each light emitting diode 5 emitted light is therefore at the reflector 2 in a lighting area 7 diffused. The arrangement shown produced by means of the parabolic reflector 2 an approximately homogeneous illumination of a portion of a side wall 8th in the cabin area of an aircraft. In other words, the illumination module shown radiates homogeneously into the illumination area 7 on the partial area of the side wall 8th ,
  • For an observer 9 , For example, a passenger sitting in the cabin, prevents the panel 3 in the sense of the "Hidden Source" principle direct observability of the or each light-emitting diode 5 from the observation area of the observer 9 , An optionally obliquely to the right to the side surface 8th given direct light failure can by the observer 9 not be recognized. Because he is unable to, the lighting module 1 from the direction of the side surface 8th to observe. Thus, the observer 9 safe from a direct light component of the light-emitting diode 5 protected.
  • The in the lighting area 7 Irradiated portion of the diode light is on the illuminated portion of the side wall 8th towards the observer 9 scattered back so that the sub-area appears bright and homogeneously illuminated. The concave curvature of the reflector 2 focuses the diffusely reflected light on its surface into the illumination area 7 and thereby homogenizes the illumination. In addition, it extends on average the light path between the or each light emitting diode 5 and the reflector 2 opposite to a different reflector shape, so that the light mixture for the observer 9 and thus the homogeneity of the illumination is additionally improved. The parabolic shape of the reflector 2 leads in particular to the fact that no angle ranges in the lighting area 7 arise for the observer 9 appear dark.
  • In 2 is another lighting module 1' shown in perspective. Visible is the reflector 2 , the aperture 3 and the side surface 4 , It becomes clear that the light emitting diodes 5 now in individual groups 10 are summarized along the longitudinal direction 9 are arranged. Every group 10 , also called a cluster, comprises four light-emitting diodes of the primary colors red, green and blue as well as a white-light diode. By appropriate control of the individual LEDs 5 each group 10 Almost any desired color can be mixed. The color mixture happens here through the diffuse reflecting reflector 2 which according to 1 is constructed, but has a different inclined parabolic shape, and by the extended light path to the observer 9 ,
  • The opening through which the light-emitting diodes 5 emitted light enters the environment, in turn, by a light-permeable cover 6 protected. That of the light-emitting diodes 5 emitted light is at the reflector 2 in a direction of observation 7 diffused. The aperture 3 prevents in the sense of the "hidden source" principle direct observability of the LEDs 5 , The desired colored lighting is generated by the proportion of diode light, which at obstacles and Bewandungen the cabin space in the direction of the observer 9 is scattered or reflected. The concave curvature of the reflector 2 For this purpose, the light diffusely reflected on the surface thereof focuses in the illumination area to be illuminated 7 into, thereby homogenizing the illumination. It also extends the light path between the or each light emitting diode 5 and the reflector 2 opposite to a different reflector shape, so that the light mixture for the observer 9 and thus the homogeneity of the illumination is additionally improved.
  • The illustrated lighting module 1' represents a single module for a line light. A number of lighting modules 1' can thus be assembled into a line lamp which extends along the entire length of a passenger compartment of an aircraft and, for example, the ceiling lighting or the illumination of a lateral operating surface is used. Such a single module comprises about ten light-emitting diode clusters 10 and has a length of about 30 to 50 cm.
