Description

(54) A HEADLAMP IN PARTICULAR FOR MOTOR VEHICLES (71) We, FORD MOTOR COMPANY LIM ITED, of Eagle Way, Brenwood, Essex, CM13 3BW, a British Company, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The invention relates to a headlamp, in particular for motor vehicles, of the type comprising a reflector body having at least two part-reflectors, formed in one piece from synthetic material and mirrored at the reflector surfaces by a vapour deposition process, which is closed off at the front by a glass lens and at the rear by at least one bulb socket.
From DT-GM 1 753 612, already a headlamp of the kind introductorily described is known in which part-reflectors for main beam and dipped beam are arranged side by side and partially overlapping.
This known headlamp has the drawback that it is relatively wide and accordingly is difficult to incorporate into smaller vehicle models for stylistic reasons.
From FR-PS 1 511 607, a headlamp substantially of the kind introductorily described is known in which a part-reflector for the dipped beam is arranged at the top inside the conventional reflector for both main and dipped beams.
This known headlamp requires no more room than a conventional headlamp but, in accordance with a stage of development which at the present time has already been left behind, is designed as a so-called singlefilament halogen lamp and is not yet available in the form of a double-filament lamp corresponding to the well-known "Bilux"-bulb design ("Bilux" is a registered trade mark).
From DT-OS 2 457 292, likewise a headlamp substantially of the kind introductorily described is known, in which a part-reflector for the mainbeam function is located at the bottom inside a conventional reflector for the dipped beam.
With this headlamp again, the same applies as has already been said in respect of the lamp disclosed in the French Patent Specification.
Thus, the known headlamps of compact design simply fulfill the conventional headlamp functions such as providing dipped and mainbeam and possibly also parking light so that for other lighting functions such as flasher light or foglamp, additional light units have to be provided at the front end of a vehicle.
Because of the development which has taken place in modern vehicle design, triggered by the realisation of the general energy situation, towards progressively lower vehicle front ends with better streamlining, the accomodation of all the requisite lights in a stylistically acceptable fashion at the front ends of small vehicles, presents a number of problems.
The object of the present invention is to avoid these problems by commencing from the double-filament halogen bulbs which are available for motor vehicle headlamps, to form a highly compact and cheap headlamp which also incorporates additional lighting functions without increasing the amount of space required, In accordance with the invention, this object is achieved in that a headlamp of the type referred to in the introductory paragraph above exhibits the features discEosed in Claim I and the subclaims.
Through the use in accordance with the invention of the headlamp reflector section which is not required for the production of the dipped beam, in order to accomodate additional lighting functions such as flasher light or foglamp, an extremely compact and inexpensive unit combining headlamp and other lights, is created for small vehicle types. Because of the high performance of modern double-filament halogen bulbs and bearing in mind the fact that the traffic densities encountered nowadays only enable main beam to be used in rare instance, the impairment of the main beam performance, which results from the headlamp design proposed in accordance with the present invention, can be accepted without any objection.
The invention will be explained in more detail making reference to a number of embodiments illustrated in the drawings.
Figure 1 is a front elevation of a headlamp in accordance with the invention Figure 2 is a section on the line II--II of Figure 1; Figure 3 is a section on the line Ill-Ill of Figure 1; Figure 4 is a similar section to that of Figure 3, through a further headlamp in accordance with the invention; Figure 5 is a similar section to that of Figure 3, through yet another headlamp in accordance with the invention.
In the Figures, a headlamp 1 consists essentially ofa reflector body 2 with part-reflectors 3 and 4 which is manufactured in one piece from synthetic material and mirrored at the reflector surfaces by a vapour deposition process. The reflector body 2 is closed off in the conventional manner at its front end by a glass lens 5 and at its rear end by a bulb socket 6 which accepts a corresponding bulb 7.
The interior of the reflector body 2 is here subdivided by a partition wall 8 adjoining the part-reflector 3 required for the dipped beam, into a headlamp space 9 and a flasher light or foglamp chamber 10 with a partreflector 4 for the particular light.
A bulb socket 11 with a corresponding bulb 12 can be inserted into the flasher light or foglamp chamber 10. The front end of the flasher light or foglamp chamber 10 is here overlapped by part of the glass lens S, this part, depending upon the particular type of light, being provided with a corresponding optical design for having an additional lens 13 with a suitable optical design, arranged beneath it.
The partition wall 8 separating the headlamp space 9 from the light chamber 10, here extends rearwards from the axially further forward part-reflector 4 for the light, and carries the integrally formed masking cap 14 which is designed to screen out unwanted scattered light in foggy conditions.
The examples shown in Figures 4 and 5, of headlamps in accordance with the invention, correspond in fundamental design largely with the headlamp in accordance with the invention shown in Figures 1 to 3, so that corresponding components have been provided with the same reference but with the addition of an apostrophe. Accordingly, too, the general design of these headlamps is not recapitulated and reference is simply made to design differences.
In the case of the headlamp shown in Figure 4, with substantially vertical glass lens 51, the one-piece reflector body 21 of synthetic material is so designed that the additional lens 131 completely separates the light chamber 10 from the headlamp space 91 This may be convenient in certain circum stances although it is advantageous in the case of a headlamp as shown in Figure 3, where the headlamp space 9 communicates with the lightchamber 10, that simultaneously with the ventilation of the headlamp space 9 corresponding measures should be provided to simultaneously ventilate the light chamber 10.
In the case of the headlamp shown in Figure 5, with a steeply inclined lens 511, the one-piece synthetic material reflector body 211 is so designed that it forms a forward-extending spacer section 15. In this case, where a very steeply inclined glass lens 51l is used, the latter is conveniently not provided with any optical prism arrangement and instead the optical arrangements will advantageously be incorporated into an additional lens 1311 which extends both over the headlamp space 911 and over the lightspace 1011. The additional lens 1311 can here, in a manner known per se, consist of synthetic material, and, at the zone located at the front of the headlamp space 911, can consist of transparent material whilst that of its zones in front of the light chamber 1011 can consist of coloured material.
It goes without saying that the lens 1311, in the situation where a foglamp is arranged in the lightchamber, can be formed in one piece from synthetic material whilst in the event that a flasher light is provided instead it can be formed by injection-moulding two elements together, formed by sticking together different coloured elements or again by a colouring operation.
In addition, it should be pointed out that although the compact and inexpensive headlamp in accordance with the invention has preferentially been designed for the use of double-filament halogen bulbs, it is entirely open to the person skilled in the art to design a headlamp in accordance with the invention to used conventional bulbs of the type sold under the trade mark "Bilux". In so doing, essentially the same advantages of compact and cheap manufacture are achieved albeit at the expense of a reduction in optical performance.
A headlamp in accordance with the invention can be manufactured irrespective of the differences in the known headlamp designs in terms of the method of attachment of the individual headlamp parts.
WHAT WE CLAIM IS: 1. A headlamp, in particular for motor vehicles, comprising a reflector body having at least two part-reflectors, manufactured in one piece from synthetic material and mirrored at the reflector surfaces by a vapour deposition process, which is closed off at the front by a glass lens and at the rear by at least one bulb socket, characterised in that the interior of the one-piece synthetic reflector body (2) is subdivided by a partition wall (8) adjoining the part-reflector (3)
