DETAILED DESCRIPTION
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
Referring to FIGS. 1 to 6, a shifting position display apparatus of a vehicle according to the present invention includes: a lens I which is light-transmissive and on which a plurality of characters or symbols are displayed; a light guide panel 3 that is arranged on a lower side of the lens 1 to be overlapped therewith; a side light emitting body 5 for illuminating light from a side of the light guide panel 3 toward the light guide panel 3; and a plurality of lower light emitting bodies 7 which are provided at the positions corresponding to the characters or symbols on a lower side of the light guide panel 3.
That is, characters or symbols for displaying a shifting range are displayed and light to be diffused is supplied to the lens 1 through the light guide panel 3 wherein the light is supplied to the light guide panel 3 from the side light emitting body 5 to diffuse and disperse the light toward the whole light guide panel 3, and further the lower light emitting body 7 supplies directly light to the respective characters or symbols of the lens 1 and thus the corresponding characters or symbols of various colors are displayed on the lens 1 in a wholly luxurious light emitting state through the light concentrated wholly or locally on the light guide panel 3.
Here, a plurality of dent portions 9 a sectional face thickness of which decreases to one side are provided on the light guide panel 3 at every locations corresponding to the character or symbol of the lens 1.
In various embodiments, the dent portions 9 are provided on a lower side of the light guide panel 3 and a sectional face thickness of the light guide panel 3 decreases from a lower side toward an upper side thereof, and as shown in FIG. 4, the denting depth of the dent portion becomes gradually deeper in accordance to the distance spaced from the side light emitting body 5 which is determined per region.
The depth of the dent portion 9 that becomes gradually deeper in accordance to the distance space from the side light emitting body 5 serves such that the light emitted from the side light emitting body 5 is diffused and reflected to illuminate the light of a wholly similar level to an upper side of the light guide panel 3, irrespective of the spaced distance, and thus the light of an uniform level is illuminated toward an upper side of the light guide panel 3 even though small number of the side light emitting bodies 5 are used.
An embossing 11 of a plurality of convexo-concaves is formed on the dent portion 9 of the light guide panel 3 to diffuse smooth the light incident on the dent portion 9.
A shield layer 13 is further provided on a lower side of the light guide panel 3 to be overlapped therewith except for the dent portion 9 for shielding the light from the lower light emitting body 7 and reflecting the light from the side light emitting body 5, and the shield layer 13 may be overlapped with the light guide panel 3 as a separate plate or applied to the light guide panel 3. Of course, the present invention may be implemented without the shield layer 13.
The side light emitting body 5 and the lower light emitting body 7 are configured to emit the light of different colors, respectively wherein the lower light emitting bodies 7 are configured to emit light of at least one colors and thus the light of various colors are displayed on the lens 1 to direct luxurious atmosphere.
A lamp or light emitting diode may be used in the side light emitting body 5 and the lower light emitting body 7, and as shown FIG. 2, a circuit board for driving the side light emitting body 5 and a circuit board 17 for driving the lower light emitting body 7 may be provided separately or a single circuit board may be provided.
According to the present invention, various colors are illuminated on a character portion for displaying the respective shifting ranges to implement luxurious feeling of a vehicle greater than same level vehicle while relatively smaller number of the light-emitting bodies are used and as a result a complexity of the electric circuit for driving the light-emitting bodies is reduced to save cost and reduce manufacturing processes.
For convenience in explanation and accurate definition in the appended claims, the terms upper or lower, and etc. are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
