Various types of lights and lighted accessory units have been developed for motor vehicles and the like.
U.S. Pat. No. 7,712,933 discloses lighted assemblies that include LED light sources that are encapsulated in a polymer material. The lighted assembly may comprise an LED light source that is connected to a light guide as shown in FIGS. 7-11 of the '933 patent. However, known vehicle lights may suffer from various drawbacks.
The present invention relates to a flexible, clear light pipe/lighted logo. The light pipe or logo may be curved and deformed for mounting on curved, inflexible surfaces. The light pipe or logo may also be utilized in situations where the part must actually flex like in applications, vehicle seat, floor mat or similar flexible vehicle trim component. It may also be utilized in non-automotive applications such as mouse pads, clothing, baggage, or stick on logos. The light pipe also provides independent control of illuminated areas by use of multiple LED's in one light engine, and splitting of light from one LED to multiple locations of illumination using the thickness of the light pipe and its shape to split the light as needed.
One aspect of the present invention is a high clarity clear/transparent and flexible light pipe having a plurality of layers of light pipes. This construction permits multiple lighted areas having illumination that is individually controlled.
The flexible lighted assembly may include a light source comprising at least one LED. The LED may optionally be encapsulated in a light transmitting material. The flexible lighted assembly may also include a plurality of overlapping sheets of flexible light transmitting material. Each sheet has first and second opposite side surfaces and a peripheral edge surface extending between the first and second opposite side surfaces. The sheets receive light from the light source and internally reflect the light to thereby guide the light through the sheets. The first and second side surfaces of each sheet includes a reflective area that reflects a substantial majority of the light from the LED internally. At least the first side surface of the sheets includes a light emitting area that permits escape of light from within the sheet whereby the light emitting area can be illuminated by the LED.
Another aspect of the present invention is a method of making a flexible lighted assembly. The method includes providing a light source and forming a plurality of light guides from thin sheets of light transmitting polymer material. The thin sheets of light transmitting polymer material have first and second opposite side faces that are generally smooth and internally reflect light introduced at edges of the sheets. The method includes treating at least a portion of the first side face of each sheet to form light emitting surface features defining light emitting areas. The method further includes overlapping portions of the light guides and operably connecting the light source to the light guides whereby light from the light source is transmitted through the light guides and illuminates the light emitting areas.
These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following appended drawings.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in
With reference to
The outer sheet or layer 4 may be made from a transparent polymer material that has been selectively coated or otherwise treated to form a first area 16 that does not transmit light, and to form a plurality of second areas 18 that transmit light therethrough. The first areas 16 may comprise ink, paint, or other layer of opaque material that blocks transmission of light. The second areas 18 may form letters, numbers, designs, or other desired shapes. The areas 18 of layer 4 may be substantially smooth, or the areas 18 may have a rough (“frosted”) surface. The areas 18 of layer 4 may be coated with a translucent colored ink or other suitable material to provide a desired lighted color. As discussed in more detail below, an LED light distribution assembly 20 is positioned within interior space 14 and illuminates the second areas 18.

With further reference to
The polymer body 30 may comprise a main portion 36 comprising a transparent polymer material, and a plurality of secondary portions 38a-38f that comprise an opaque, light-blocking polymer material. The secondary portions 38 are disposed between the LEDs 26A-26F to prevent light 40A-40G from LEDs 26A-26G, respectively, from entering the other light guides 24A-24G. The secondary portions 38 may comprise walls or layers of material extending between the upper surface 42 and lower surface 44 (see also
Referring again to
Each of the light guides 24A-24G may comprise a thin sheet of transparent polymer material such as acrylic, polycarbonate, or other material. The light guides 24A-24G preferably have a thickness of about 0.5 mm or less, and the light guides 24A-24G are slidably disposed relative to one another. As discussed in more detail below, this permits the light assembly 1 to flex without damaging the individual light guides 24A-24G and other components. Each of the connectors 46A-46G of polymer body 30 may have a thickness that is equal to the thickness of the corresponding light guides 24A-24G, and the individual connectors 46A-46G may be vertically positioned to align with the individual light guides 24A-24G. Specifically, connectors 24A-24G may comprise “full height” connectors 46A1-46G1 as shown in
Referring again to
The areas 18A-18G of light guides 24A-24G, respectively, may comprise rough surface areas that are formed by laser treatment of the upper surfaces 62A-62G of light guides 24A-24G, respectively. The outer surfaces of the light guides 24A-24G are preferably smooth (except at areas 18A-18G) to thereby internally reflect light from LEDs 26 except at the areas 18A-18G. The areas 18A-18G may comprise a plurality of surface features extending transverse relative to the adjacent smooth surface areas. This causes light to escape at areas 18A-18G, while being reflected internally in other areas. Light from the LEDs 26 causes the areas 18A-18G to be illuminated, without illuminating the other areas of the light guides 24A-24G. Because the light guides 24A-24G are made of a transparent material, light emitted from the second areas 18A-18G is emitted upwardly through the other light guides, and through the areas 18 (
The flexible lighted assembly 1 may include a single light engine 22 that is operably connected to the first ends 28A-28G of light guides 24A-24G. Alternatively, the second ends 29A-29G (
As discussed above, the LEDs 26A-26G may comprise white LEDs, and the light guides 24A-24G may comprise transparent material. If this arrangement is utilized, the illuminated areas 18A-18G will generally have a white color. Alternatively, one or more of the LEDs 26A-26G may comprise a colored LED to thereby cause the areas 18A-18G to selectively illuminate with different colors. Also, the light guides 24A-24G may comprise colored polymer material to provide colored illumination at the second areas 18A-18G.
Also, the individual LEDs 26A-26G may be configured to illuminate at different times. For example, the electrical circuit 32 may be operably connected to a switch (not shown). Upon actuation of the switch, the LEDs 26A-26G may illuminate in sequence with a delay of, for example, one second between the illumination of each LED 26A-26G. The individual LEDs 26A-26G may be selectively turned on and off according to various predefined sequences to provide various lighting effects.
With further reference to
The upper sheet or member 104 of the flexible lighted assembly 101 may include a flat first area 116 that is covered by a layer of opaque material to block light. The upper sheet or member 104 also includes transparent areas 118A-118G that transmit light from light guides 124A-124G to thereby illuminate the areas 118A-118G. The areas 118A-118G may comprise raised regions as shown in
With further reference to
The individual LEDs 26A-26C may be controlled by an electrical circuit 32 to thereby selectively illuminate lighting zones 156A-156C. For example, the flexible light assembly 130 may be configured to illuminate only the second lighted zone 156B under certain conditions, and illuminate all three zones 156A-156C under other operating conditions. Also, the zones to be lighted may be controlled by a user.

The flexible lighted assemblies of the present invention may be utilized in a variety of applications. For example, the flexible lighted assemblies may be utilized in connection with a rigid, curved surface. The flexible lighted assemblies can be fabricated and then flexed to match the curved surface as required at the time the lighted assembly is mounted to a vehicle structure (e.g. door sill, dashboard, etc.). In this way, fabrication of the illuminated assembly is simplified because it does not need to be molded to a specific shape prior to installation. Furthermore, production tolerances and the like in the curved surface to be covered are well-tolerated by the flexible lighted assembly.
Furthermore, the flexible lighted assemblies of the present invention may be utilized in parts or other components that are flexed in use. For example, the lighted assemblies may be utilized to provide lighted floor mats for motor vehicles. Also, the lighted assemblies may be positioned on/in an upholstered, padded surface that is flexed in use. For example, the lighted assembly of the present invention may be positioned below a layer of upholstery or the like in a vehicle seat, and the upholstery may be provided with openings corresponding to the illuminated areas. For example, the flexible lighted assembly 101 (
The materials utilized to form the outer sheet 4 and tray 8 of flexible lighted assembly 1 and upper sheet 104 and tray 108 of flexible lighted assembly 101 may be selected to have the necessary degree of flexibility and/or stretch required for a particular application. For example, the upper layer 4 or 104 may be made from a relatively rigid transparent polymer material (e.g. acrylic, polycarbonate, etc.), and the tray 8 or 108 may be made from a flexible/stretchable material. For example, the tray 8 or 108 may be made from foam, an elastomeric material, a thermoplastic elastomer such as Santoprene®, urethanes, silicones, neoprene, latex, or EPDM. In general, at least one of the outer layer 4/104 and tray 8/108 is made from a stretchable material to permit flexing of the flexible lighted assembly 1/101. The flexible lighted assemblies 130, 170, and 195 may also be constructed utilizing flexible/stretchable materials to achieve the desired degree of flexibility.
