Definitions
- the present invention relates to a panel assembly for an automotive vehicle and, more particularly, to a panel assembly having an integrated stop signal which indicates braking of the vehicle.
- an upper stop light is generally centrally located near and separate from the rear window of the vehicle.
- the upper stop light generally includes a box containing a light bulb with a red filter (lens) facing rearwardly.
- the box is mounted on the rear shelf of the vehicle next to the rear window and at the base of the rear window.
- a panel assembly for an automotive vehicle which has a transparent panel having opposing first and second surfaces.
- a portion of the first surface includes refractive structure integral with the panel.
- At least one light source is positioned at an edge of the panel for introducing light into the panel.
- the refractive structure reflects light from the light source out through a portion of the second surface.
- a film laminate is positioned generally opposite the refractive structure.
- the method comprises the steps of: molding a transparent panel to have opposing first and second surfaces such that a refractive structure is defined in a portion of the first surface during molding; providing a film laminate on a portion of the second surface so as to generally oppose the refractive structure; and orienting at least one light source along an edge of the panel such that light emitted therefrom may be reflected by the refractive structure and passed through the film laminate.
- Fig. 1 is a perspective view of a panel assembly of the invention shown mounted at the rear portion of a vehicle; and Fig. 2 is a cross-sectional view of the panel assembly taken along the line 2-2 of Fig. 1.
- a panel assembly for an automotive vehicle is shown, generally indicated at 10, which embodies the principles of the present invention.
- the panel assembly 10 includes a transparent panel 12, preferably made from molded plastic, having a first surface 14 and an opposing, second surface 16. A portion of the first surface 14 includes refractive structure 18.
- the refractive structure 18 is integral with the panel 12 and is formed during an injection molding process.
- the refractive structure may define a multifaceted reflector.
- refractive structure 18 is generally rectangular or trapezoidal in overall shape and is comprised of a plurality of preferably parallel facets formed in panel 12 and extending in the width direction of panel 12.
- a film laminate 20 is provided on the second surface 16 at a position generally opposite the refractive structure 18.
- the laminate 20 is a thin, transparent film formed of thermoplastic material such as polycarbonate or polyester resin.
- the laminate 20 is also red in color to provide a brake light, as will be explained in more detail below.
- At least one light source 22 is positioned at an edge of the panel 12 for introducing light into the panel.
- the light source 22 includes at least one LED light source which is received in a bore 24 defined in a bottom edge of the panel. It can be appreciated, however, that the number of LED' s provided are dependent upon the amount of light which is to be seen or emitted through the film laminate 20. In the illustrated embodiment, three LED's are provided. Moreover, LED's produced by the Hewlet- Packard company are preferred.
- the light sources are operably connected to the vehicle's braking system and are thus responsive in a conventional manner to a brake signal from the vehicle so that the light sources, and thus red film laminate 20, will illuminate upon application of the vehicle's brakes.
- the panel assembly 10 may be utilized as a rear window for an opening 26 in a vehicle 28.
- the panel assembly 10 is sealingly mounted with respect to the rear opening 26 in a conventional manner.
- the material choice of the window is clear thermoplastic material taken from the group consisting of polycarbonate, polymethyl methacrylate, and cyclic polyolefin and may include an abrasion resistant coating 30.
- the panel 12 and integral refractive structure 18 are integrally molded together in an appropriately shaped mold assembly used in conjunction with an injection molding process.
- the coating 30 shown in Fig. 2 is applied to only second surface 16, the coating may be applied to either or both surfaces 14 and 16.
- the coating preferably comprises a thermoset material taken from the group consisting of polysiloxane, acrylic resin, and aliphatic polyurethane.
- the coating may be applied by placing a sheet of coating material onto a surface of the mold prior to the injection molding process, by dip coating the entire fabricated panel, or by spraying or flow coating one or both surfaces of the fabricated panel.
- the panel assembly 10 could be treated with a UV absorbing agent to resist UV damage.
- Such agents, including polydimethylsiloxane could also be added to or included with the coating 30.
