Definitions
- the present invention relates to a light guide for displaying lettering and / or symbols, in particular as a logo, according to the preamble of claim 1.
- Such light guides are known per se and serve to convey information.
- the light guide which typically can also include a logo
- the light guide with the logo is then inserted from behind into the panel, the logo depending on the nature or profile protrudes through the recess and is flush with the surface of the panel. By illuminating the logo from the area behind the panel this can be visualized visually well.
- the blind areas of the light guide or its logo with an opaque filler For this purpose, it is known from the prior art, the blind areas of the light guide or its logo with an opaque filler. Initially, the actual logo is formed on the light guide (for example, by a plastic injection process) and then the blind areas are filled (for example, in a subsequent second injection process) with the selected filler material.
- the object of the invention is therefore to further develop a light guide of the aforementioned type, with which a harmonic representation of the logo in the installed state in the panel can be realized.
- the backlit logo should convey a high-quality overall impression and underline the value of the associated device.
- the logo should be particularly easy and safe to manufacture.
- the invention is achieved by a light guide according to claim 1 and a method for producing this light guide according to claim 7.
- the invention is based on the recognition that a particular harmonic appearance or the smooth integration of the light guide or its logo in the surrounding aperture is then feasible if the material of the filler, which are used in the blind areas, the material of the surrounding Aperture corresponds.
- This has the advantage that the filled areas in the light guide and the outer circumferential aperture show the identical color, the same degree of gloss and the identical aging behavior.
- the logo with its filled-in blind areas optimally adapts to the recess of the surrounding panel, without it being apparent that the fillings in the logo and the surrounding panel were produced separately from each other. Rather, the desired impression is created that only the glowing parts of the logo (and not its blind areas) were used instead of the aperture in this.
- the light guide comprises a base plate extending substantially in a longitudinal direction X and a transverse direction Y. It has an upper side and a lower side and has a plate thickness which extends in a direction Z perpendicular to the directions X and Y. At the top of the base plate while a logo profile is formed, which extends in the Z direction up to a maximum thickness d from the top away. The thickness may in particular correspond to the thickness of the diaphragm, in which the light guide is to be used. Then, the optical fiber is located with the top of its base plate from the rear of the panel, while the logo profile protrudes through the recess provided in the corresponding recess and preferably terminates flush with the diaphragm surface.
- the molded logo profile is inventively Deutschenleuchtbar, wherein the base plate and the overlying logo profile in the Z direction of at least one blind area is interspersed, which is not to be illuminated. Therefore, each blind area is filled by a filler.
- the material of the filling body is selected such that it corresponds to the material of the diaphragm into which the light guide is to be inserted.
- a backlight unit is provided for the fluoroscopy of the base plate and logo profile.
- the light guide according to the invention provides this backlight unit.
- the backlight unit is typically flush with the underside of the baseplate, allowing good light into the baseplate or logos formed integrally thereon.
- the backlight unit can directly contain suitable bulbs. Alternatively, however, it can also have suitable light guides with which supplied light is deflected into the base plate or the logo profile or scattered in this direction. The actual bulbs then sit outside the backlight unit. Individual sections or elements of the logo profile can be colored differently.
- the base plate itself is designed as a backlight unit for the purpose of screening the logo profile.
- the base plate itself could already contain suitable bulbs or serve for forwarding or conversion of light, which can penetrate through the logo profile and thus improves the visual appearance of the logo inserted into the panel.
- the base plate with the logo profile also functions as a backlight unit, it can also be colored for color enhancement.
- this embodiment eliminates the need for a separate to the base plate or the logo profile backlight unit and thus allows a particularly flat and cost-saving design of the light guide.
- Another advantageous idea of the light guide according to the invention leads to a backlight unit, which has separate colored light chambers to illuminate the logo profile depending on the location with different light. This ensures that individual sections of the logo profile can be specifically illuminated in a different color than is the case for adjacent sections. This advantageously increases the variety of lighting options or possible applications. It is conceivable, in particular, that individual color light chambers can each be exposed to differently colored light, so that identical sections of the logo profile can optionally shine in different light.
- the backlight unit can be colored continuously or in sections in order to apply presettable areas of the logo profile with correspondingly colored light.
- a (“white”) light fed into the backlight unit can nevertheless be used to illuminate individual sections or elements of the logo profile differently. This reduces the lighting expenditure or the number of lamps of different colors and thereby reduces the costs.
- a further advantageous embodiment of the invention is concerned with the shape of the packing in the blind areas. It is provided according to the invention that the at least one filler body comprises a filling web extending in the Z direction. The Gresteg serves to introduce the filler into the blind area.
- the cross-section of the filling body in the XY plane should be smaller than the cross-section to be filled in the blind area at the height of the maximum thickness d, ie approximately in the plane of the aperture into which the light guide with its logo profile is to be inserted.
- the material of the filler is introduced through the Gearsteg in the respective blind area, which material fills the full extent of the blind area in the X-Y direction only in the region of maximum thickness d in the Z direction.
- the advantage here lies in the minimization of the filling material to be introduced, whereby the stress cracking in the filling material or in the surrounding material of the logo profile is reduced.
- the Golfsteg leads from the bottom of the base plate in the Z direction to just below the maximum thickness d, where only the blind area undergoes the full extent in the X and Y direction. The amount of filling to be introduced is thus minimized as best as possible.
- a method for producing the light guide which is intended for use in a diaphragm, according to the invention comprises two method steps:
- a base plate to produce a logo profile wherein the base plate extends substantially in a longitudinal direction X, and a transverse direction Y. It has an upper side and a lower side and a plate thickness, which is formed substantially in the direction Z.
- the method step further includes the formation of a logo profile, which is integrally formed on the top of the base plate. It extends in the Z direction up to a maximum thickness d from the top of the plate, with the base plate and the logo profile being formed using a common material component.
- the at least one blind area is filled, which passes through the base plate and the overlying logo profile in the Z direction and is not provided for fluoroscopy.
- the filling of the blind areas is carried out with a second material component, wherein the material according to the invention corresponds to the material of the diaphragm.
- the inventive method is used for the advantageous production of optical fibers of the type described above with the corresponding representational advantages.
- the filling of the blind areas can be carried out in each case via a riser formed in the blind area whose cross-section in the X-Y plane is smaller than the cross-section of the blind area to be filled in the amount of the maximum thickness d.
- Fig. 1 is a perspective view of a light guide according to the invention.
- Fig. 2 is a plan view of the light guide of FIG. 1 with two mutually perpendicular sectional views.
- a light guide 1 which has the logo of the company Bosch to the subject.
- the light guide 1 in this case comprises a base plate 2, which extends substantially along an X-Y plane and has a small thickness in the Z direction.
- a logo profile 3 is formed at the bottom 6 of the base plate 2 opposite top 4.
- the logo profile 3 comprises an unspecified anchor symbol and a lettering formed from five capital letters "B O S C H".
- Logo profile 3 and base plate 2 form an integral unit, wherein the logo profile is provided for backlighting with suitable lighting means.
- the base plate 2 with the logo profile 3 formed thereon is intended for use in a diaphragm 10 which is partially indicated in FIG. 2.
- a complementary formed to the logo profile 3 recess was introduced (for example punched out) in the aperture 10 to accommodate the logo profile 3 accordingly.
- the logo profile 3 extends - starting from the surface 4 of the base plate 2 in the Z direction upwards - for example by a dimension d, which determines the maximum height of the logo profile 3.
- the height d corresponds approximately to the thickness of the diaphragm 10, as can be seen in FIG. 2, section A - A.
- the base plate 2 and the molded thereon logo profile 3 are made of translucent material, which may be colored.
- the base plate 2 can be formed at the same time as Backlightunit 7, through which the light introduced from the bottom 6 of the base plate in the direction of the top of the fourth molded logo profile 3 scattered, broken, colored or otherwise can be converted to achieve the desired optical lighting impression.
- Backlightunit 7 through which the light introduced from the bottom 6 of the base plate in the direction of the top of the fourth molded logo profile 3 scattered, broken, colored or otherwise can be converted to achieve the desired optical lighting impression.
- the arrangement of a separately formed backlight unit T is conceivable, as indicated in Fig. 2, section BB.
- Fig. 1 shows an example of three blind areas 5a, 5b and 5c, which are formed in the logo profile 3 and are not provided for fluoroscopy. Therefore, packing 8 a , 8 b and 8 C are introduced into the corresponding blind areas, which are opaque and thus enable a correct typeface lighting the logo profile 3 from its underside.
- Fig. 2 shows the optical fiber 1 in a plan view and in two sectional views A- A and BB.
- the blind areas 5 a , 5 b and 5 C are examples of the logo "BOSCH" selected areas of the logo profile, wherein the anchor symbol arranged to the left has further blind areas, which are not designated in more detail.
- the section AA shows the light guide 1, wherein it is inserted from below in the only excerpts indicated aperture 10. It can still be seen there that the blind areas 5 b and 5 C are filled by complementary filler 8 b and 8 C. These are opaque according to the invention, so that when the logo profile 3 is illuminated from the underside 6 of the base plate 2, the correct visual representation can be seen.
- Each filler 8b and 8 C (the filler 8a is not shown for reasons of cut) comprises a Golfsteg 9 b , 9 C , which - starting from the bottom 6 of the base plate 2 - extends in the Z direction upwards.
- each filler Shortly before the logo profile 3 and thus each blind area 5 a , 5 b and 5 C reaches the maximum height d, the filler widens and assumes the full extent in the XY plane. So instead of penetrating in full and constant width, the base plate 2 and the logo profile 3, each filler comprises a Greeg in the sense of a riser through which the filler is to be introduced into each blind area. The full extent in the XY direction undergoes each filler only in the range of maximum thickness d. In cross-section AA, the fillers thus assume approximately the shape of a "T".
- This form avoids accumulation of material and thus shrinkage stresses in the region of the filling body or the base plate 2, on the other hand covers the transverse to the Golfsteg spread material at the upper end of the "T" of each filler the associated Golfsteg, so that an undisturbed visual impression of the lettering or the total logo profile results.
- All packing 8 are inventively formed from the same material as the diaphragm 10th
