DETAILED DESCRIPTION
(15) As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
(16) The accompanying drawings are intended to provide a further understanding of the embodiments of the invention. They illustrate embodiments and serve in conjunction with the specification to explain principles and concepts of the invention. Other embodiments and many of the mentioned advantages will become apparent in view of the drawings. The elements in the drawings are not necessarily shown true to scale to each other.
(17) Throughout the figures of the drawings, identical, functionally identical and identically acting elements, features and components are respectively designated by the same reference numerals, unless stated otherwise.
(18)
(19) The detail of a vehicle body component 10, which is specifically a radiator grill or a bumper strip of a vehicle, shown in
(20)
(21) The detail of a vehicle body component 10 shown in
(22) Here, the lighting means arrangement 16 is configured as a LED strip being bendable at least in the longitudinal direction thereof. The LED strip may include a plurality of LEDs 18 arranged one behind the other and electrically interconnected.
(23) Here, as shown in
(24) Here, the LED strip may include at least one substrate 20, which may generally include silicone or a silicon-based or other semiconductor. In addition, a further substrate layer, for example a harder substrate, or a base plate of metal may be provided, which makes the LED strip mechanically robust. An insulation layer may be provided between the two layers.
(25) Moreover, the body part 10 may include a mounting means 24, which is disposed in the depression 14 of the base body 12. Here, the mounting means 24 is configured to fix the lighting means arrangement 16. Thus, fixing the lighting means arrangement 16 to the base body 12 may be configured for long-term use. However, the lighting means arrangement 16 may be fixed in different ways. For instance, the lighting means arrangement 16 may be integrally fixed or connected to the mounting means 24. Therefore, an integral fixation in the mounting means 24 provides a fastening option designed for safety. Alternatively, the mounting means 24 may be configured as a separate component. The lighting means arrangement 16 may be fixed to the mounting means 24 by at least one of the following options: extruding, injection molding, gluing, locking, clip-fastening, welting or clamping. These options may also be combined with each other. Thus, secure fastening may be realized, which additionally may allow simple replacement of the illumination means arrangement.
(26) Furthermore, the body component 10 may include the cover 26 configured to cover the depression 14. Here, the cover 26 includes at least one portion 28, which is configured to be transparent, partially transparent or translucent so that at least some of the light generated by the LEDs 18 can be radiated to the outside. As shown in
(27) As an example, the base body 12 and the cover 26 are formed as one part or one piece. In such a case, the lighting means arrangement 16 may already be integrated into the base body at the time of manufacturing the same. Thereby, the manufacturing process, for example by injection molding, is simplified, whereby costs can be reduced. Furthermore, an outer surface 27 of the cover 26 at the light exit side 13 may be formed to be flush with a surface 11 of the base body 12 surrounding the depression 14. Thus, this gives rise to a smooth surface without edges and steps between the respective surfaces 11, 27 of the base body 12 and the cover 14. Thereby, on the one hand, an illumination having a particularly natural appearance is achieved. In this way, on the other hand, when illumination is turned off, the integrated lighting means arrangement is not visible or only hardly visible. Therefore, the vehicle body component also appears natural, when illumination is turned off.
(28) Moreover, the lighting means arrangement 16 may include an at least partially transparent outer layer 22, wherein the LEDs 18 are disposed between the substrate 20 and the outer layer 22. Here, the outer layer 22 is configured to be transparent, partially transparent or translucent so that at least some of the light generated by the LEDs can be radiated to the outside and in a solid angle having a size of up to 4π. Here, the outer layer may be made elastic in that the outer layer 22 contains an elastic material, such as soft plastic. Thereby, the LEDs 18 are better protected against mechanical impacts. Moreover, the outer layer 22 protects the LEDs 18 against environmental influences. The outer layer may extend across the entire surface of the substrate 20 or may extend, as shown in
(29) As an additional aspect, the configuration of the depression 14 in terms of the length L and particularly the depth T thereof allows to adjust the light generated by and radiated from the LEDs 18 according to desired outwardly acting luminous characteristics at the light exit side 13. Since the LEDs 18 usually radiate over a relatively large solid angle, the radiation angle of the light may be limited, for example, by increasing the depth T of the depression 14. The solid angle may be further reduced by configuring the walls 15 of the depression 14 to absorb light. Vice versa, a small depth T of the depression 14 and reflective walls 15 of the depression 14 increase the solid angle of the radiated light.
(30)
(31) The lighting means arrangement 16 shown in
(32) Furthermore, in
(33) Moreover, it can be seen that the at least partially transparent portion 28 of the cover 26 is entirely surrounded by the opaque portion 30. Thereby, the solid angle of the radiated light is limited. Additionally, the solid angle may be limited or even increased in that the at least one at least partially transparent portion 28 of the cover 26 is formed as an optical element, such as a lens. In this case, the type and shape of the lens are not limited and may include, inter alia, convex lenses, concave lenses, convexo-concave lenses, meniscus lenses, axicons, and in particular cylindrical lenses of the mentioned shapes particularly suitable for the embodiment of
(34)
(35) It can be seen that the lighting means device 16 is disposed in the correspondingly formed depression 14 in a state of being bent along the longitudinal direction. As shown in the following figures, the bending shown is basically not limited to the bending direction along the longitudinal direction of the lighting means arrangement 16.
(36) In
(37)
(38) In the embodiment of the lighting means arrangement 16 shown in
(39) Moreover, in this embodiment, the lighting means arrangement 16 is also bent along the width thereof, which may be enabled, for example, by a flexible configuration of the substrate 20 or by a substrate body 20 having a greater thickness. Thus, the lighting means arrangement 16 may be configured in general so that the lighting means arrangement 16 is configured to be bendable in all spatial directions.
(40)
(41) In this embodiment, the LEDs 18 are arranged at any distances. If necessary, this may also be desired. Moreover, the contact terminals 32a, 32b are arranged at opposite ends of the lighting means arrangement 16. This may also be desired according to the conditions of the vehicle body part 10. As a matter of course, a circuit connecting the LEDs 18 to each other needs to be adjusted.
(42)
(43) In
(44) Besides the LEDs 18, the lighting means arrangement 16 may also comprise further electronic components. For instance, the lighting means arrangement shown in
