STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
n/a
FIELD OF THE INVENTION
The present invention relates to a method and system for illuminating emblems, and in particular, to illuminating emblems on a vehicle.
BACKGROUND OF THE INVENTION
Emblems are commonly placed on vehicles to indicate the make and model of the vehicle or to exhibit another message or logo. Thus, an emblem may be a logo with or without lettering which depicts a sports team, a religious symbol or other message. Emblems are normally placed on the front portion of a car hood, the front grill or on a side panel or rear panel of the vehicle. A problem with current emblems is that they cannot be seen in the dark, or they are illuminated in a way that may be expensive, difficult to assemble, or not aesthetically pleasing. Further, current emblems are sometimes substantially modified from their manufactured appearance.
SUMMARY OF THE INVENTION
The present invention advantageously provides a method and system for illuminating an emblem on a vehicle. According to one aspect, the invention provides an emblem body having a front side facing away from the vehicle and exhibiting the emblem and having a rear side facing toward the vehicle. The body is shaped to provide at least a partial housing for mounting at least one LED. A space between the body and the vehicle when the body is mounted upon the vehicle is provided. At least one LED is mounted in the at least partial housing and oriented to transmit light through the space between the body and the vehicle so that light illuminates one or more contours of the body.
According to another aspect, the invention provides a body shaped to exhibit a symbol and to form a housing for an LED that is mounted to transmit light toward the surface through a space between the body and the vehicle to illuminate one or more contours of the symbol.

DETAILED DESCRIPTION OF THE INVENTION
Before describing in detail exemplary embodiments that are in accordance with the present invention, it is noted that the embodiments reside primarily in combinations of apparatus components and processing steps related to implementing a back-lit vehicle emblem. Accordingly, the system and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
Referring now to the drawing figures in which like reference designators refer to like elements, there is shown in FIG. 1 a rear view of a back-lit vehicle emblem 1 constructed in accordance with the principles of the present invention, as disclosed herein. The emblem has a body 2 with a front surface 3 as shown in FIG. 2. The body 2 may be in the shape of a logo and/or may include lettering depicting a make or model of the vehicle, or may exhibit some other design such as a sports team's logo, a religious symbol, etc. At least one light emitting diode 5 is located in a hollow portion 6 of the body 2. The rear surface 4 has at least one edge 7. A portion of the at least one edge 7 is a raised edge 8 so that when the at least one LED 5 is activated, light emitted from the LED 5 will shine through a space between the body and the vehicle under the raised edge 8, thereby illuminating the emblem.
FIG. 2 is a perspective view of the back-lit emblem of FIG. 1. The emblem 1 has a body 2 with a front surface 3 and a rear surface 4 shown in FIG. 1. The rear surface 4 has at least one edge 7 which includes a raised edge portion 8. When the at least one LED 5 is activated, light propagates through the space between the emblem and the vehicle and illuminates the raised edge portion 8. Also, the light may reflect from a surface of the vehicle and illuminate the raised edge portion 8 and thereby illuminate the emblem contours.
FIG. 3 is a front view and FIG. 4 is a side view of another back-lit emblem. The emblem 1 has a body 2 with a front surface 3. The body 2 may be in the shape of a logo and/or lettering. Some portions may be translucent features 9 that emit light from the LED 5 embedded in a hollow portion 6 of the body 2. Light travels from the LED 5 through the space between the body and the vehicle to illuminate outer edges of the emblem 1. The emblem 1 may have at least one spacer 10 mounted on the vehicle 11 using a mounting mechanism 12, such as adhesive, double-sided tape, screws, nuts, bolts, etc. The spacer 10 creates a space between a rear surface 4 of the emblem 1 and the vehicle 11, thereby allowing light to travel through the space between the emblem 1 and the vehicle 11 to reflect from the vehicle 11 and illuminate along raised edges 8 that are spaced away from the vehicle 11 by the spacer 10.
FIG. 5 is a block diagram of components for illuminating an emblem as described herein. An LED 5 is connected through a switch 16 to at least one power source 13. The power source 13 may be a vehicle battery 15 or the vehicle electrical system 14. The LED 5 may be activated by the switch 16. In one embodiment, when certain lights of the vehicle, such as the headlights or brake lights, are turned on, the LED 5 is also turned on.
It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described herein above. In addition, unless mention was made above to the contrary, it should be noted that all of the accompanying drawings are not to scale. A variety of modifications and variations are possible in light of the above teachings without departing from the scope and spirit of the invention, which is limited only by the following claims.
