Description
Vehicle light assembly and vehicle including at least one vehicle light assembly The present invention relates to a vehicle light assembly and a vehicle including at least one vehicle light assembly.
Vehicles, such as automotive vehicles, use many different interior and exterior lights and light assemblies for various purposes. Interior lighting assembiies include vanity mirror lights, reading lights and instrument panel lights. Exterior lighting assemblies, such as headlamps, turn signal indicators, brake lights and taillights, are provided for mainly safety purposes. However, the appearance of the exterior lighting assemblies is also taken into consideration during their design and construction, as the outer appearance of the vehicle can play a role in the decision to purchase one vehicle rather than another.
In some vehicle light assemblies, some of the light energy is wasted since it is not directed towards a particular target. This misdirected and, therefore, wasted light may cause diffi-culty in the form of glare so that masking is sometimes used to keep light emanating in a desired direction. However, masking does not aid in reducing the wasted energy.
US 6352,359 Bi discloses a vehicle light assembly including a diffuser surface structure.
The diffuser surface structure provides light homogenising, directing and shaping capabili- ties. Therefore, a vehicle light assembly can be provided which has an output shape distri-bution corresponding to the area to be illuminated. Less energy is wasted by misdirection of the light.
It is, however, desirable to further increase light usage of vehicle light assemblies. This may enable the energy consumption to produce the desired illumination level to be reduced.
A vehicle light assembly is provided that comprises a plurality of point light sources ar-ranged in a predetermined pattern, a light diffuser that homogenises light emitted from the plurality of point light sources to provide a smooth continuous pattern of light having a pre-determined distribution envelope and an outer lens. The light diffuser and the distribution envelope comprise at least one curved portion.
The light diffuser homogenises the light emitted from the plurality of point light sources so as to provide a single distribution envelope in which the light is uniformly emitted. There-fore, instead of a plurality of separate point light sources being visible when looking at the outer lens, a single illuminated area is observed. The distribution envelope of the light dif-fuser describes the spatial extent of the illumination.
The vehicle light assembly, therefore, has the advantage that the light emitted from the plu- rality of point sources is directed by means of the light diffuser so that the light actually leav-ing the vehicle light assembly is directed into a single predetermined distribution envelope.
Since the hght is homogenised by the light diffuser to provide a smooth, continuous pattern, illumination over the predetermined distribution envelope is provided. This makes better use of the light emitted from the plurality of point light sources.
Additionally, the light diffuser and the distribution envelope comprise at least one curved portion. This enables the vehicle light assembly to be used for vehicle lights having a com-plex form, such as panel display lights and daylight running lamps, which may be circular or have a complex curved contour around the forward and side facing surfaces of the vehicle.
In an embodiment, the light diffuser has a shape which corresponds to the pre-determined pattern of plurality of point light sources. For example, if a single row of point light sources is arranged in a semi-circle, the light diffuser may have the same or a similar semi-circle shape.
In an embodiment, the distribution envelope is elongate. The distribution envelope may have a strip-like form comprising at least one curved portion. The distribution envelope may have a length that is at least S times as long as its breadth, for example.
In an embodiment, the distribution envelope corresponds in its spatial extent to the shape of the light diffuser. The distribution envelope may be spatially larger than the spatial extent of the light diffuser.
The shape of light diffuser may also correspond to the predefined pattern of a plurality of point light sources. For example, if the plurality of point light sources is arranged in a semi-circle the light diffuser and the distribution envelope may be provided with a semicircular form. Therefore, a single illuminated semicircular area is provided by the plurality of point light sources due to the presence of the light diffuser.
In a further embodiment! the light diffuser further directs the light in a predetermined direc-tionality. Therefore, in addition to homogenising and smoothing the pattern of light within the predetermined distribution envelope, the light is also directed towards a predetermined target. This embodiment can be used to limit the spread of the light emitted over the distri-bution envelope and, for example, to reduce glare in unwanted directions.
The light diffuser may comprise a micro-sculpted surface. Methods of fabricating a suitable micro-sculpted surface are disclosed in US patents US 6,352,359 81, US 5,365,354 and is us 5,534,386, which are incorporated herein by reference in their entirety.
The light diffuser may be fabricated by producing a master diffuser by exposing photoresist material to a source of light and then replicating this master diffuser into one or more sub masters of a more durable nature. The master diffuser may be initially created optically, for example holographically. The master diffuser may also be created mechanically, for exam-ple, by patterning the surface of a copper blank with a laser.
The light diffuser may be provided in the form of a sheet which is positioned between the plurality of point light sources and the outer lens of the vehicle light assembly. A light dif-fuser in the form of an additional sheet is useful in that the light diffuser may be fabricated separately from the rest of the components of the vehicle light assembly. This enables the light diffuser to be provided as an option for the vehicle light assembly. Also, by providing the light diffuser in the form of a sheet, this may simplify the manufacturer of the light dif-fuser.
In an alternative embodiment, the light diffusion is integrally formed in a further component of the vehicle light assembly, for example, in an inner surface of the outer lens. This em-bodiment has the advantage that a further component does not have to be inserted into the vehicle light assembly during manufacture and aligned with the further components.
The light diffuser and the distribution envelope may comprise a curved portion positioned in a single plane. For example, the tight diffuser and the distribution envelope could comprise a segment of a circular ring.
The light diffusion and the distribution envelope may comprise a three-dimensional curved portion. This embodiment may be used to form complex curved contours for exterior vehicle lights such as daylight running lights.
The plurality of point light sources may be provided by a plurality of light emitting diode de-vices. Light emitting diode devices are useful in that they consume less energy for the amount of illumination provided compared to filament-based light bulbs.
The vehicle light assembly may also further comprise a nontransparent housing that is posi-tioned adjacent to a least one side of the outer lens. The nontransparent housing can be used to further increase the apparent illumination from the vehicle light assembly, particu-larly in the case that the housing has a dark colour. This embodiment may also be used to give a characteristic appearance to the vehicle light assembly and provide an additional recognition feature which may be representative of the particular vehicle or the particular manufacturing company.
The vehicle light assembly may also further comprise a reflector. The reflector is typically suitably positioned so as to reflect light from the plurality of light sources in the direction of the outer lens and further increase the illumination level and light usage.
As discussed above, the vehicle tight assembly may be an exterior light assembly or an interior vehicle light assembly. In one particular embodiment, the vehicle light assembly is a daylight running lamp.
A vehicle is also provided which includes at least one vehicle light assembly according to one of the embodiments described above.
Particular embodiments will now be described with reference to the accompanying draw-ings.

Figure 1 illustrates a schematic side view and figure 2 illustrates a schematic three-dimensional view of a light vehicle assembly 1 according to a first embodiment.
The vehicle light assembly 1 includes a plurality of point light sources 2. In this embodi-ment, each of the light sources is a light emitting diode (LED). The plurality of point light sources 2 are arranged in a predefined pattern. In this particular embodiment, the plurality of light sources 2 are arranged in a single row and form a segment of a circle, as is illus-trated in the three-dimensional view of figure 2.
The vehicle light assembly 1 further comprises a light diffuser 3 which, in this embodiment, has the form of a sheet with a micro-sculpted surface 4. The light diffuser 3 is positioned between the plurality of point light sources 2 and an outer lens 5 of the vehicle light assem-blyl.
The light diffuser 3 homogenises the light emitted from the plurality of light sources 2 to provide a smooth continuous pattern of light having a pre-determined distribution envelope.
The smooth and continuous pattern of the light in the distribution envelope is schematically indicated in figures 1 and 2 by the plurality of arrows 6. Therefore, the light diffuser 3 acts to homogenise and smooth the discontinuous light pattern emitted by the light emitting diodes so that a single uniform light envelope is observable from the outside the outer lens 5. The distribution envelope of the light is. therefore, elongate and strip-like due to the presence of the light diffuser 3.
Figure 3A illustrates a portion of a vehicle comprising a daylight running lamp 1' according to a second embodiment and Figure 38 illustrates the vehicle 7 comprising the daylight running lamp 1' according to the second embodiment.
The daylight running lamp 1' comprises a plurality of LED light sources 2 which are ar-ranged in a row, one behind the other, around an outer three-dimensional contour of the vehicle headlight B of the vehicle 7. The light sources 2 face to the front and to the side of the vehicle 7. The daylight running tamp 1' also includes a light diffuser 3' which has a curved contour that follows the pattern of the point light sources 2 in three-dimensions.
For illustrative purposes, four of the LEDs are left uncovered by the light diffuser 3' in Figure 3A in order to better illustrate the effect of the light diffuser 3'.
The distribution envelope 9 is illustrated in figure 3A and 38 which is created by the light diffuser 3'. Light diffuser 3' and the distribution envelope 9 have spatial extent which is which corresponds to one another. The light sources 2 which are covered with the light dif-fuser 3' provide a single contLnuous uniformly illuminated envelope 9 and a single, curved elongated stripe-like lamp effect.
In contrast, the distribution envelope 10 of the light produced by each the plurality of point light sources 2' which remain uncovered by the light diffuser 3' is circular resulting in indi-vidual illuminated areas that are separate from one another.
Figure 4 illustrates a vehicle light assembly 1" according to a third embodiment. The vehicle light assembly 1" according to the third embodiment differs from the vehicle light assembly 1' of the first and second embodiments in that the tight diffuser 3" is provided as an integral part of the outer lens 5'. In particutar, the inner surface 11 of the outer lens 5' is provided with a micra-sculpted surface 4 which provides the light diffusing and homogenising proper-ties.

FigureS illustrates a light diffuser 12 for use with the vehicle light assembly according to one of the embodiments described above. The light diffuser 12 is provided in the form of portion of a two-dimensional sheet 13. If the light diffuser 12 isto have a three-dimensionally curved contour in the vehicle light assembly, the two-dimensional sheet form is modified accordingly.
The light diffuser 12 may be fabricated by first producing a master diffuser comprising one or more micro-sculpted portions corresponding to the desired shape of the light diffusers for the particular vehicle tight assembly. This master diffuser may be used to produce sub rnas- ter diffusers or the final light diffuser by moulding, for example, plastic, onto the micro-sculpted master diffuser.
Figure 6 illustrates exemplary vehicle light assemblies 14, 15 comprising a non-illustrated light diffuser. These vehicle light assemblies 14, 15 comprise a housing 16 which surrounds the outer lens 5 of the vehicle light assembly 14, 15. The housing is non-transparent and, in this example, black. The housing acts not only to hold the vehicle lighting assembly in place, but also has the effect of increasing the apparent illumination from the outer tens 5.
Furthermore, the shape of the housing 16 and outer lens 5 of the vehicle light assembly 14, may be designed so as to have a pleasing appearance and also to provide a recognition feature of a vehicle, a model line or a vehicle manufacturer. In the embodiments illustrated in Figure 6, the vehicle light assemblies provide etongated strip-like illumination.
Figure 7 illustrates an exploded view and an assembled view of a further vehicle light as-sembly 17 comprising a light diffuser 3. The vehicle light assembty 17 comprises a black housing 16 which is positioned behind a printed circuit board 19 comprising a plurality of light emitting diodes 20 providing the point light sources.
The light diffuser 3 has a three-dimensional contour which follows that of the housing 18 and the printed circuit board (PCB) 19. The vehicle light assembly 17 further comprises an inner lens 20 having a base portion which has a contour corresponding to that of the hous- irig is, PCB 19 and the light diffuser 3 and which also has protruding portions 21. The vehi-cle light assembly also includes a front lens 22 which covers the other components. The assembled structure illustrates that the vehicle light assembly 17 comprises a complex three-dimensional form with three protruding regions illuminated homogenously and uni-formly by the plurality of point sources 2 due to the presence of the three-dimensional light diffuser 3.
Figure 5 illustrates the inner lens 20 of the vehicle light assembly 17 illustrated in figure 7.
The inner lens 20 comprises a clear double moulding 23 which includes black portions 24, for example provided by a black gloss paint, and chrome portions 25 in addition with to the transparent lens 22. The chrome portions 25 also function as reflector sidewalls for the ye-hide light assembly 17.
