`
`Description
`
`
`The invention relates to a signal lamp
`
`for motor vehicles having a housing and/or a
`fastening means to be installed into or
`attached to a motor vehicle body, with at
`least one transparent end plate, and with a
`number of light sources that are developed
`as light-emitting diodes.
`patent
`
`The
`German
`published
`application DE 40 03 807 A 1 discloses a
`motor vehicle warning lamp that is used as a
`brake light. The signal lamp has a housing
`and a fastening means so that the signal
`lamp can be attached to the body of a motor
`vehicle or installed into a motor vehicle. The
`housing is developed in such a fashion that it
`has a transparent end plate in the direction of
`radiation of the light. To generate light, a
`number of light sources are arranged in the
`housing, which are developed as light-
`emitting diodes.
` With the known embodiment, it is
`disadvantageous that a large number of
`light-emitting diodes
`are
`required
`to
`generate a sufficiently high signal- and
`warning effect of the signal lamp. This leads
`to an expensive and high-effort construction,
`which furthermore has a high current
`consumption. With the known embodiment
`of
`the
`signal
`lamp,
`it
`is especially
`disadvantageous that because of the known
`radiating characteristics, the light-emitting
`diodes have to be arranged in a short
`distance to one another to obtain an even
`illumination of the transparent end plate, and
`a large radiating surface that also has a high
`signal- and warning effect can be obtained
`only if a large number of light-emitting
`diodes are arranged in the signal lamp,
`which increases the production cost and the
`current consumption.
`
`The invention is based on the task of
`creating a signal lamp for motor vehicles,
`which is simple and economical, has a high
`luminosity and a high signal- and warning
`effect, ensures an even illumination at a low
`current consumption, and is developed in an
`optimally flat and space-saving fashion.
`
`
` According to the invention, this task is
`achieved in that each light-emitting diode
`has an associated elongated light guide
`element; in that at least one face of each
`light guide element is developed as a light-
`coupling surface for the light of a light-
`emitting diode; in that the side of each light
`guide element facing away from the light-
`emitting surface has light-deflecting means;
`and in that at least two light guide elements
`are arranged in parallel side-by-side behind
`the end plate.
`light-
`that each
`
`It
`is advantageous
`emitting diode has an associated elongated
`light guide element because in this way, the
`light generated by each light-emitting diode
`can be converted in a simple and economical
`fashion via an elongated light guide element
`into a desired light distribution with a wide
`radiating area.
`
`In this context, it is advantageous that at
`least one face of each light guide element is
`developed as a light-coupling surface for the
`light of a light-emitting diode because this
`ensures the optimum utilization of the light
`provided by each light-emitting diode.
`
`The fact that the side of each light guide
`element facing away from the light-emitting
`surface has light-deflecting means results in
`the advantage that the light of the light-
`emitting diode coupled into the light guide
`element can be deflected into a specific
`light-radiating direction.
` Here, it is advantageous that at least two
`light guide elements are arranged in parallel
`side by side behind the end plate, which
`ensures
`a
`simple
`and
`economical
`construction and producibility; a
`large-
`surface signal lamp with high luminosity
`and a high signal- and warning effect can be
`constructed, which furthermore has only a
`low current consumption at an even
`illumination because due
`to
`the good
`utilization of the light of the light-emitting
`diodes, only a small number of light-
`emitting diodes are required. It is especially
`advantageous here that the signal lamp can
`be developed in a flat and especially space-
`saving fashion.

`
`It is advantageous if the light guide
`
`elements
`are
`developed
`cylindrically
`because
`this
`leads
`to a simple and
`economical producibility of the light guide
`elements and furthermore, an especially
`favorable light distribution for signal lamps
`can be achieved because on the one hand, an
`especially favorable distribution of the light
`is achieved in the light guide element
`because of the reflections occurring in the
`light guide element, and on the other hand,
`an especially large even distribution is
`obtained during the radiation when the light
`radiates across
`the
`face because
`the
`cylindrical form leads to a magnifying glass
`effect.
`light-
`the
`that
`is advantageous
`
`It
`deflecting means at the side of each light
`guide element facing away from the light-
`emitting surface are prisms because on the
`one hand, this leads to a simple and
`economic producibility because the prisms
`can be introduced into the body of the light
`guide element at the same time that the light
`guide element is produced, for example in
`an injection molding process, and on the
`other hand, the scattering angle and/or the
`deflection of light emitted by the light guide
`can be influenced in an especially simple
`fashion by varying the prism angles and/or
`the prism division and/or the prism depth,
`which means that depending on the required
`light
`radiation, varying
`light-radiating
`characteristics can be achieved
`in an
`especially simple and economical fashion.
`
`The fact that the light-emitting surface
`of each light-emitting diode protrudes into
`the light guide element, and that the form of
`the light-coupling surface of each light guide
`element is adapted to the form of the light-
`emitting surface and
`the
`light-radiating
`characteristics of the light-emitting diode,
`leads to the advantage that the light radiated
`by the light-emitting diode via its light-
`emitting surface is optimally coupled into
`the light guide element, depending on the
`type of the light-emitting diode being used,
`which means that the loss of light is kept
`relatively low.
`
`In this context, it is advantageous that
`each light guide element has a light-coupling
`
`area with a diameter that tapers toward the
`light-coupling surface because in this way,
`for example with light-emitting diodes that
`have a small light-emitting surface but
`radiate the light widely, the light that hits the
`walls of the light-coupling area cannot leave
`the light guide element because of the
`effective total reflections and is reflected at
`a favorable angle
`into
`the
`light guide
`element, which results in a particularly good
`utilization of the light made available and
`furthermore increases the even distribution
`of the light in the light guide element.
`
`The fact that all light-emitting diodes
`are arranged at one side of the light guide
`elements arranged in parallel leads to the
`advantage of an especially simple and
`economical structure of the signal lamp.
`
`It is advantageous that with adjacent
`light guide elements arranged in parallel, the
`light-emitting
`diodes
`are
`alternately
`arranged on both sides, which results. in
`particular with
`a
`large
`longitudinal
`expansion of the light guide elements and
`their parallel arrangements. in an especially
`even illumination.
`especially
`is
`it
`
`In
`this
`context,
`advantageous that the surface opposite the
`light-coupling surface is mirrored, which
`increases the evenness of the illumination
`with light coupled only at one side.
`
`It is advantageous that the light-emitting
`diodes are arranged on both sides of the light
`guide elements, which especially with light
`guide elements of a large length leads to an
`especially even illumination.
` An embodiment of the signal lamp that
`is especially simple and economical to
`produce is obtained when the light-emitting
`diodes are arranged in rows on at least one
`common printed circuit board.
`
`It is advantageous if the end plate has
`light-deflecting means; on the one hand, this
`increases the evenness of the illumination
`and on the other hand, specified and desired
`light distributions can be generated in a
`simple and economical fashion.
`light guide
`
`Because a number of
`elements arranged in parallel with light-
`emitting diodes of the same color forms a
`group that generates a uniform signal light, a

`
`signal lamp that is especially space-saving
`and has a flat structure can be produced,
`which has a specified illumination surface
`with especially even
`illumination and
`therefore a high signal- and warning effect.
`
`In this context, it is advantageous that
`the signal lamp has at least two groups with
`light-emitting diodes of the same or different
`color to produce especially space-saving and
`flat signal lamps that can display signal light
`of the same or different color, either at the
`same time or separately.
`
`The fact that the parallel light guide
`elements of one group are developed in one
`piece leads to the advantage that they can be
`produced
`in an especially simple and
`economical fashion.
`
`If the signal lamp is used as tail light
`and/or brake light and and/or blinker and/or
`rear backing up light in motor vehicles, it is
`advantageous
`if
`the
`signal
`lamp
`is
`constructed in a space-saving and especially
`in a flat fashion, has a low weight and has a
`low current consumption.
` According
`to
`the characteristics of
`Claim 16, the resulting advantages are that
`the light generated by the light-emitting
`diodes has a high intensity and a wide,
`conical radiation, which means that the
`number of light-emitting diodes can be kept
`low, and a wide, large-area radiation of light
`is obtained.
` An embodiment of the object of the
`invention is shown in the illustrations and
`explained below using the figures.
`
`The same or similar components have
`the same reference symbols in all figures.
`
`They show in

`
`an embodiment of a light-
`emitting diode.
`Fig. 1 shows an embodiment of a signal
`
`lamp according to the invention. It has a
`housing (G) with which the signal lamp can
`be installed into a motor vehicle body or
`attached to a motor vehicle body. With the
`embodiment shown here, the signal lamp
`has four groups (GP) that can generate light
`of the same or a different color at the same
`time or at different times. One of the groups
`can be a taillight, for example, whereas
`another one can be a brake light, another one
`can be a blinker, and another group (GP)
`represents a backing up light. As shown
`here, the individual groups can be covered
`by individual transparent end plates (A) of
`the same or different colors. However, in
`another embodiment, the signal lamp can
`have only one transparent end plate (A) that
`can be the same or a different color. The
`color of the end plate (A) may differ from
`the color of
`the
`light emitted by
`the
`respective group (GP) so that when the light
`generation by the respective group (GP) is
`turned off, the color may be a different color
`than when the light generation is turned on.
`
`In another embodiment of the invention,
`where the signal lamp is inserted into the
`opening of a car body, for example, a
`housing (G) is not necessary. In that case,
`the housing (G) can be replaced by a
`fastening means (B).
` As shown in the area designated Y in
`Fig. 1, each group (GP) has a number of
`light sources that are developed as light-
`emitting diodes (LED). Each light-emitting
`diode (LED) has an associated elongated
`light guide element (L) into which the light
`generated by the respective light-emitting
`diode (LED) is coupled. To obtain an even
`illumination, at
`least
`two
`light guide
`elements (L) are arranged in parallel side by
`side behind the end plate (A). With the
`embodiment shown here, ten light guide
`elements (L) per group (GP) and
`the
`associated light-emitting diodes (LED) are
`
`Page 4 of 19

`
`arranged in parallel behind the respective
`transparent end plate (A). In this way, a
`large-area even
`light signal source
`is
`generated, which has a space-saving and flat
`construction and a large signal- and warning
`effect.
`Fig. 2 shows the detail Y corresponding
`
`to Fig. 1 in an enlarged scale. The light-
`emitting diodes (LED) are arranged in rows
`and attached on a common printed circuit
`board (LP) with electrical contact. Here,
`each light-emitting diode (LED) has an
`associated elongated light guide element (L)
`that is developed in conical shape. The light
`guide elements (L) are arranged in parallel
`side by side, with the light being fed in on
`one side in such a way that with adjacent
`light guide elements (L) arranged in parallel,
`the light is fed in from different sides. In
`other
`embodiments,
`the
`light-emitting
`diodes (LED) can all be arranged at one side
`or at both sides.
`
`To fasten and securely space the light
`guide elements (L) arranged in parallel, they
`are mounted on a fastening means (B), as
`shown in the present example. In another
`example, the light guide elements (L) of a
`group (GP) can also be developed in one
`piece.
`Fig. 2 furthermore shows that the side of
`
`each light guide element (L) facing away
`from the light-emitting surface shown here
`has
`light-deflecting means which,
`for
`example, is developed here as prisms (P)
`that are arranged transversely to the main
`light-radiating direction.
`Fig. 3 shows, in an enlarged scale, a
`
`section through an embodiment of a light
`guide arrangement according to Fig. 2. The
`light-emitting diode (LED) has a base and a
`lensoid light-emitting surface. Said light-
`emitting surface protrudes into the light
`guide element (L). For an optimal utilization
`of the light emitted by the light-emitting
`diode (LED), the form of the light-coupling
`surface (LK) of the light guide element (L)
`is adapted to the form of the light-emitting
`surface and the light-radiating characteristic
`of the light-emitting diode (LED). With the
`embodiment shown here, the light guide
`element (L) has a light-coupling area (LB)
`
`with a diameter that tapers toward the light-
`coupling surface (LK). Depending on the
`development of the light-emitting surface
`and the light-radiating characteristic of the
`light-emitting diode (LED) being used, the
`light-coupling area (LB) can have a different
`shape than the conical shape shown here; for
`example, it can also be spherical. In another
`exemplary embodiment, a
`light-coupling
`area (LB) may not be needed at all,
`depending on the light-emitting diode (LED)
`being used. As already described under Fig.
`2, each light guide element (L) has prisms
`(P) at the side facing away from the light-
`emitting surface, some of which are shown
`here as examples. Depending on the desired
`light scattering and the light distribution to
`be generated, the scattering angle of the
`radiated light can be changed by changing
`the prism angles and/or the prism division
`the prism depth. Fig. 3 shows
`and/or
`examples of a few prisms (P). To elaborate
`on the path of the rays in the light guide (L),
`two light rays are drawn [in the figure] as
`examples, which are reflected by the prisms
`(P) in the direction of radiation and leave the
`light guide element (L). In the embodiment
`shown here, [they] are coupled into the light
`guide element (L) only at one side. To
`improve the even distribution of the light,
`the surface (F) opposite the light-coupling
`surface (LK) is therefore mirrored. The light
`guide element (L) is shown in a shortened
`fashion in Fig. 3. The required length of the
`light guide elements (L) can differ between
`different applications, as can the diameter of
`the light guide elements (4).
`Fig. 4 shows an example of an
`
`arrangement for a signal lamp according to
`the invention. With the arrangement shown
`here, the light guide elements (L) are
`arranged horizontally in parallel behind a
`transparent end plate (A). The end plate (A)
`can be part of a housing (G) and/or a
`fastening means (B).
`Fig. 5 shows a section through a signal
`
`lamp
`according
`to
`the
`invention
`corresponding to Fig. 4. Examples of the
`paths of the rays of the six light guide
`elements
`(L) shown here, which are
`arranged in parallel vertically behind the

`
`to guarantee an especially simple and
`economical producibility.
`Fig. 9 shows, with a section through the
`
`light guide arrangement according to Fig. 8
`that because of
`the magnifying effect,
`viewed from direction (R), the surfaces
`having the prisms (P) only need to take up a
`small portion of the rear side of the light
`guide elements (L), depending on
`the
`desired light distribution and the selected
`radius of the cylindrical light guide elements
`(L), to obtain a high even distribution of the
`radiated light.
`Fig. 10 shows a preferably useable light-
`
`emitting diode (LED). Said LED has a body
`(K); a semiconductor element (H); electrical
`connecting elements (M); a reflector (E);
`and a lens (I). The form of the reflector (E)
`and the form of the lens (I) are developed so
`that an optimally large light flux of the light
`generated by the semiconductor element (H)
`is radiated via the lens (I) with a wide,
`conical radiating characteristic.
`
`For example, a
`light-emitting diode
`(LED) by Hewlett Packard, type HPWR-
`A200, can be used.

`space requirement and in particular the flat
`structural form of the signal lamp, and on
`the other hand
`the
`even
`radiating
`characteristic obtained with simple means.
`In another embodiment, the transparent end
`plate (A) can have light-deflecting means for
`specifically scattering and/or deflecting the
`light from the light guide elements (L).
`Fig. 6 shows a light guide arrangement
`
`already known from Fig. 2 and Fig. 3, with
`the paths of the rays drawn in. The light
`radiated into the light guide element (L) by
`the light-emitting diode (LED) is reflected
`multiple times in the light guide, which
`leads to a high even distribution. The
`reflection of the light that hits the prisms (P)
`is determined by
`the
`form and
`the
`arrangement of the prisms (P) and leaves –
`as is shown – the light guide element (L) in
`the direction of light emission. To increase
`the even distribution of the light in the light
`guide element (L) when the light is coupled
`in on one side, the surface (F) opposite the
`light-coupling surface (LK) is mirrored.
`Fig. 7 shows the detail X corresponding
`
`to Fig. 6. In this representation, the path of
`the rays in the light guide element (L) and
`the reflection of the light rays that hit the
`prisms (P) are visible; because of the prism
`angles, said light rays are reflected in such a
`fashion that they leave the light guide
`element
`(L) with
`the desired
`light
`distribution
`in
`the direction of
`light
`emission. The prisms are advantageously
`arranged so that no free surfaces are created
`between the prisms, which could lead to
`undesired light effects.
`Fig. 8 shows an examp le of an
`
`arrangement for the light guide elements (L)
`of a signal lamp according to the invention
`where the light is coupled in at one side via
`the light-coupling surfaces (LK). It shows
`the rear side of the light guide elements (L)
`with a surface having prisms (P). In this
`embodiment,
`the
`surface
`(F)
`is also
`developed in mirrored fashion. The light
`guide elements (L) are cylindrical and
`adjacent
`light guide elements
`(L) are
`connected in one piece in this embodiment

`Beschreibung
`
`Die Erfindung betrifft eine Signalleuchte ffir Kraft-
`fahrzeuge mit einem Geh'ause und/oder einer Befesti-
`gungseinrichtung zum Ein- oder Anbau an oder in eine
`Kraftfahrzeugkarosserie, mit mindestens einer transpa-
`renten AbschluBscheibe und mit einer Anzahl Licht-
`
`quellen, die als Leuchtdioden ausgebildet sind.
`Aus der deutschen Offenlegungsschrift DE 40 03 807
`A1 ist eine Kraftfahrzeug-Warnleuchte bekannt, die
`Verwendung als eine Bremsleuchte findet. Die Signal-
`leuchte weist ein Gehéuse und eine Befestigungseinrich-
`tung auf, so daB die Signalleuchte an oder in eine Kraft-
`fahrzeugkarosserie an- oder eingebaut werden kann.
`Das Gehéuse ist dabei derart ausgebildet, daB es in
`Lichtabstrahlrichtung eine transparente AbschluBschei-
`be aufweist. Zur Erzeugung von Licht sind in dem Ge-
`hause eine Anzahl Lichtquellen angeordnet, die als
`Leuchtdioden ausgebildet sind.
`Bei der bekannten Ausffihrungsform erweist sich als
`nachteilig, daB zur Erzeugung einer groBem ausreichen-
`den Signal- und Warnwirkung der Signalleuchte eine
`groBe Anzahl Leuchtdioden verwendet werden muB.
`Dies ffihrt zu einer kostenintensiven, aufwendigen Kon-
`struktion, die zudem eine hohe Stromaufnahme auf-
`weist. Als besonders nachteilig erweist sich bei der be-
`kannten Ausffihrungsform der Signalleuchte, daB
