The intercalated screen is formed by a sheet of transparent material, the faces of which are moulded so as to define an array of converging lenses (42). The covering screen comprises a sheet formed by an outer layer (20) of opaque material and an inner layer (22) of transparent material. The outer layer has an array of through-holes (24), each of which is filled by a projection (26) of the transparent material of the inner layer. The converging lenses of the intercalated sheet are aligned with the projections to concentrate through each of the latter an elementary beam formed by part of the parallel beam of light from the parabolic reflector. <IMAGE>
Description
SPECIFICATION
Light unit for motor vehicles
This invention relates to a light unit for a motor vehicle of the kind comprising at least one light bulb, a parabolic reflector lying behind the light bulb to reflect the light in a substantially parallel beam, a covering screen which lies in front of the light bulb and has an array of small transparent areas, and an intercalated screen which is located between the light bulb and the covering screen and is formed by a sheet of transparent material, the faces of which are moulded so as to define an array of converging lenses, each aligned with one of the transparent areas to concentrate through the latter an elementary beam formed by a part of the parallel beam.
An arrangement of this kind is proposed in
German Patent No. 956,566. This patent refers to a rear lamp with a reflector, in which a covering screen has an array of reflecting prisms on its internal surface. Between the prisms, the internal surface of the covering screen has an array of planar or convex areas. In this lamp, the intercalated screen is moulded as an array of biconvex lenses, each of which concentrates a part of the beam from the reflector into an elementary beam which passes through the covering screen in the areas between the prisms.
It is foreseen that, in the near future, trends in motor vehicle styling, particularly in the field of light units comprising one or more lights such as side lights, direction indicators, rear fog lamps and reversing lights, will turn to products which may be defined as hidden or masked, or in which the unit has a light-emitting face which is the same colour as the bodywork or a matching colour. It is also foreseen that, in the production of these units, the trend will be towards black opaque surfaces which follow the design trends developing in respect of other details, such as bumpers, radiator grilles, shock-resistant side trimmings, etc.
A unit according to the German Patent No.
956,566 is not capable of satisfying the design requirements envisaged above, since the covering screen is of a coloured or colourless transparent material such as that used in the more traditional light units or ordinary reflectors.
The object of the present invention is to provide a light unit of the kind referred to which is capable of satisfying the aforesaid design requirements.
According to the invention in its broadest aspect there is provided a light unit of the kind referred to, characterised in that the covering screen comprises a sheet formed by an outer layer of opaque material and an inner layer of transparent material, the outer layer having an array of through-holes each of which is filled by a projection of the transparent material of the inner layer, and defines one of the transparent areas.
The invention enables a covering screen to be made with an opaque surface in whatever colour may be desired. The surface will exhibit a simple array of spots corresponding to the through-holes and the projections. With a strong concentration of light in very narrow elementary beams the exit points of the light on the outer surface of the covering screen may be so small as to be practically unnoticeable when the unit is unlit.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:
Figure 1 is an exploded perspective view of a light unit according to the invention
Figure 2 is a cross section through the screens of the unit on an enlarged scale, taken in the plane indicated by the line Il-Il of Figure 1 with the two screens assembled;
Figure 3 is a perspective view, on an enlarged scale, of a portion of the intercalated screen, and
Figure 4 is a cross-section, on an enlarged scale, of the area indicated IV in Figure 2, in which the transparent materials of the screens are unshaded for the sake of clarity.
Referring to Figure 1, a light unit according to the invention includes a box-like base 10 for fixing to the bodywork of a motor vehicle. In the base 10 are incorporated a pair of adjacent sub-units, each of which comprises a light bulb 12 and a parabolic reflector 14 lying behind it. Usually the two subunits 1 2, 14 have different functions; for example, one may be a side or tail light and the other a flashing direction indicator. In other examples the sub-units are stop lights, rear fog lamps and reversing lights.
A covering screen 18, shown in detail in
Figures 2 and 4, is fixed to the base 10 by screws 1 6.
The covering screen 1 8 comprises a facing sheet formed by an outer layer 20 of opaque material with a smooth external surface, and an inner layer 22 of colourless transparent material.
The outer layer 20 has an array of through-holes 24, each of these holes being filled by a projection 26 of the transparent material of the inner layer.
For reasons which will be explained later, the through-holes 24 and the projections 26 have a frusto-conical shape with the smaller ends situated at the external surface of the outer layer 20.
The external ends of the projections 26 are defined by flat, circular surfaces 27 which are flush with the external surface of the outer layer 20 and complete it. In this manner the external surface of the screen 1 8 is completely smooth, as is desirable if one is to avoid road dust and dirt collecting on it.
One arrangement of the array of holes 24 and projections 26 is shown in Figure 1, where the circular areas corresponding to the external end faces of the projections are indicated at 27. These areas are distributed over the whole external surface of the screen 1 8, although only a portion of the latter has been shown.
In alignment with the projections 26 and the holes 24, the internal surface of the inner layer 22 has an array of part-spherical concave areas 28, the centres of curvature of which are indicated by C1.
Preferably, the whole of the screen 1 8 is moulded in plastics material. There are various techniques which enable the simultaneous or successive moulding of an opaque plastics material, such as that in the layer 20, and a transparent plastics material, such as that in the layer 22 and its projections 26, to form a single piece. In particular, the layer 22 may be of polymethyl methacrylate, and the layer 20 may be of any suitable plastics material containing an opaque and colouring filler. Use may also be made of two distinct layers, such as 20 and 22, which are simply coupled together mechanically. In this case the opaque layer 20 may be of metal and the
layer 22 of glass or plastics material.
An intercalated screen 30 is arranged between the covering screen 1 8 and the light bulb 12, and
is made of a transparent material, preferably a
plastics material such as polymethyl methacrylate.
The screen 30 is in the form of a sheet fixed within
the confines of the screen 1 8, in the example
shown, by screws 32 and interposed spacers 40.
The two surfaces of the intercalated screen 30
are moulded so as to define an array of converging
lenses 42, each converging lens 42 being aligned
with a respective concave area 28 and a
respective projection 26. As will be appreciated,
each concave area 28 forms a diverging lens with
the external end face 27 of the respective
projection 26.
The converging lenses 42, as shown in
Figure 3, are convex menisci which face the
incident light from the reflectors 14. Their convex
surfaces 44 are part-spherical surfaces formed on
the internal surface of the intercalated screen 30
in a honeycomb-like hexagonal pattern 46. The
concave surface of the menisci are part-spherical
concave areas 48 formed on the external surface
of the intercalated screen 30. One arrangement of
the converging lenses 42 is shown in Figure 1,
with the concave surfaces indicated at 48. In this
case, also, only a portion of the lenses have been
shown although they occupy the whole screen 30.
In Figure 4, the centre of curvature of the
concave surface 44 is shown by C2, and the centre
of curvature of the convex surface 48, which
coincides with the second focal point of the lens
42, is shown as F1. This second focal point F, lies
within the transparent layer 22, that is, within the
thickness of the diverging lens 27, 28.
Figure 4 shows the limit rays L of a parallel
beam of elementary light incident from one of the
reflectors 14, which is transmitted through a
convergent-divergent lens arrangement
comprising the lens 42 and the lens 27, 28. The
lens 42 causes the elementary beam to converge
towards its second focal point F,, but the diverging
lens 27-28 displaces the focal point to F2, the second focal point of the convergent-divergent lens arrangement.The second focal point F2 is adjacent, and beyond, the external surface of the screen 1 8. The elementary beam which passes through the diverging lens 27, 28 is a conical beam of minute width, and the projection 26 and
its hole 24, having a similar taper, are arranged so
as to permit the passage of the whole concentrated elementary beam which, after passing through the convergent-divergent lens arrangement, emerges from the screen 1 8.
As stated in the introduction, one requirement which the covering screen 1 8 must satisfy is that the areas 27 on its external surface be practically imperceptible to the eye; this means that these areas must be extremely small. With a layer 20 of black or coloured opaque material, this requirement may be satisfied with areas 27 having a diameter 1 (Figure 4) of 1 mm. On the other hand, it is appropriate for the optical unit to be of compact dimensions, in the longitudinal direction of light emission as well as transversely, and also that substantially all the light emitted from one of the light bulbs 12 be reflected by the respective reflector 14 and emerge from the unit.
In order to achieve good longitudinal compactness, the intercalated screen 30 and covering screen 1 8 should be as close to each other as possible. The honeycomb arrangement of the converging lenses 42 need not be very wide, since it is known that such an arrangement permits the optimum usage of the area available.
Moreover, this arrangement has the advantage of avoiding dead spaces between one converging lens and another, so that the intercalated screen 30 is capable of transmitting practicaliy all the light.
By producing the intercalated screen 30 and the layer 22 of the covering screen 18 in polymethyl methacrylate, the aforesaid conditions may be satisfied, preferably with the following dimensions (Figure 4): - diameter 0, of the areas 27 1 mm - distance d1 between the sheets
18,30 4.2 mm - thickness d2 of the sheet 1 8 4 mm - thickness d2 of the transparent
layer 22 2.5 mm - thickness d4 of the opaque layer 20
and the length of the
projection 26 1.5 mm - overall thickness d5 of the
sheet 30 4.8 mm - distance d6 of the centres of
curvature C, of the concave areas
28 from the layer 22 2.1 mm - radius r, of the concave
areas 28 2.3 mm - distance d7 of the centres of
curvature F1 of the concave
surfaces 48 from the
sheet 30 6.1 mm - radius r2 of the concave
surfaces 48 7 mm - distance da between the centres of
curvature F1, C2 of the
concave surfaces 48 and the
convex surfaces 44 6.3 mm - radius r2 of the convex
surface 44 4.6 mm - diameter p2 of the circumscribed
circle of the hexagonal
pattern 46 8 mm
In a unit according to the invention which comprises two or more sub-units, each with a light bulb 12 and a reflector 14, it is possible to use each sub-unit for a different coloured light; the term "different colour" also including a white light.
For this purpose it is sufficient to produce the intercalated screen 30 with as many different coloured areas as there are sub-units which are to emit lights in these colours. For example, if the sub-unit 12, 14 on the left in Figure 1 is for a tail light and/or a rear stop light which should give off a red light, the left-hand area 30a of the sheet 30 will be red in colour; if the sub-unit 12, 14 on the right in Figure 1 is for a direction indicator which has to give off an orange light, the corresponding area 30b of screen 30 will be orange in colour.
Similarly, in the case of a front side light or a white reversing light the corresponding areas of the screen 30 will be colourless, and in the case of a red rear fog lamp the corresponding area of the screen 30 will be red.
Modern methods of moulding plastics materials enable a single intercalated screen 30 formed by several adjacent areas of differently coloured or colourless material to be produced easily. Thus, in
Figure 1 the broken line 30c shows the boundary between the two areas 30a and 30b of different colours.
The various colours of the intercalated sheet will not be visible through the common covering plate 1 8 when the respective lights are unlit and the surface will be seen with the uniform colour of its opaque material.
