Description
1 k.
AUTOMOBILE HEADLAMP 2337321 The present invention relates generally to automobile headlamps and more particularly to an automobile headlamp having an upper and a lower lamp, the upper portion of the headlamp being made smaller in width than the lower portion thereof.
In order to meet front-portion design requirements for recent automobiles, it has been desired that as shown in Fig. 8 a headlamp HL' disposed on both lateral sides of a radiator grille is formed in a triangular or trapezoidal shape in that the upper portion of the headlamp is made smaller in width than the lower portion thereof as seen from the front side of the automobile (hereinafter referred to as "in front elevation"). In the case of compact cars whose width dimension is restricted, the width dimension of the headlamp HL' is also designed so that a low and a high beam lamp are arranged vertically, for example, because of the restriction imposed on the width dimension of the car. Consequently, rotary parabolic reflectors Rl and R2 respectively constituting the low and high beam lamps are disposed vertically in the lamp body LB of a headlamp of the sort mentioned above.
However, arranging the two triangular or trapezoidal reflectors vertically in the lamp body will result in necessitating making smaller the width dimension of the reflector Rl of the low beam lamp installed on the upper side because the width dimension of the upper portion of the lamp body LB is smaller than that of the lower portion thereof. Therefore, the area of the reflector R1 of the low beam lamp is made smaller and this makes it hardly possible to secure not only a desired light distribution pattern but a desired quantity of irradiation light. If an attempt is made to secure a desired light distribution pattern and a desired quantity of irradiation light by increasing the vertical dimension of the upper reflector, the area of the lower reflector may be required to be decreased. If the vertical dimension of the upper lamp is set different from that of the lower lamp, the external appearance of the headlamp will be worsened when one of the lamps is lighted.
An object of the present invention is to provide an automobile headlamp that can be triangular or trapezoidal in front elevation and is also designed to not only secure a light distribution pattern and a quantity of irradiation light which are required for safety driving but also improve the external appearance of the headlamp when the headlamp is switched on.
An automobile headlamp according to the present invention comprises a floodlight type lamp principally constructed of a condenser lens and an elliptic reflector, and a ref lector type lamp principally constructed of a parabolic reflector, and is characterized in that the floodlight type lamp is disposed above the reflector type lamp. Preferably, the floodlight type lamp and the reflector type lamp are integrally installed inside one lamp body which is triangular or trapezoidal in front elevation. Further, an aiming mechanism for tilting the floodlight type lamp together with the reflector type lamp is provided inside the lamp body. Preferably, a pivotal fulcrum portion, a vertical aiming mechanism and a lateral aiming mechanism which constitute of the aiming mechanism are respectively disposed in positions around the floodlight type lamp.
An automobile headlamp that is triangular or trapezoidal in front elevation is accomplished by disposing the lightweight reflector type lamp under the floodlight type lamp which can make desired quantity of irradiation light obtainable and also covers small area in front elevation. Therefore, there is provided such headlamp as is capable of securing the desired quantity of irradiation light and is stable in light-distribution characteristics.

An embodiment of the present invention will now be described with reference to the drawings. Fig. 1 is an outside drawing of the front portion of an automobile f itted with a headlamp according to the present invention, wherein a left and a right headlamp HL are installed on the respective left- and right-hand sides of the radiator grille of the front portion of an automobile, the headlamp HL having a substantially trapezoidal shape whose inner side edge on the inside of a vehicle body is tilted. Each of the headlamps HL contains a low beam lamp TBL located on the upper side and a high beam lamp on the lower side. According to this embodiment of the invention, further, a turn-signal lamp TSL is installed in an area adjacent to the low and high beam lamps TBL and RBL on the outer side of the vehicle body.
3 - Fig. 2 is an elevational view of the right-side headlamp jut of both the aforementioned headlamps; Fig. 3, a horizontal sectional view taken on line A A of Fig. 2; Fig. 4, a vertical sectional view taken on line B B thereof; Fig. 5, an exploded perspective view of the principal part of the headlamp as seen from the front side thereof; and Fig. 6, an exploded perspective view of the principal part of the headlamp as seen from the back surface side thereof.
As shown in these drawings, the headlamp according to this embodiment of the invention incorporates the low beam lamp TBL, the high beam lamp RBL and the turn-signal lamp TSL in one lamp body 1. More specifically, the trapezoidal lamp body 1 in front elevation and a trapezoidal front lens 2 in front elevation which is fitted in the front opening of the lamp body constitute a lamp chamber. A floodlight type lamp as the low beam lamp TBL is installed inside the upper area of the lamp chamber, whereas a reflector type lamp as the high beam lamp RBL is installed in the lower area of the lamp chamber. Further, a reflector type lamp as the turnsignal lamp TSL is installed inside an area adjacent to the low and high beam lamps TBL and RBL. In this case, the front lens 2 is fitted tightly to the lamp body 1 by fitting a sealing leg 2a formed on the peripheral edge of the front lens into a sealing groove la which is formed in the peripheral edge of the opening of the lamp body 1 and filled with an adhesive.
The f loodlight type lamp 3 as the low beam lamp TBL comprises an elliptic reflector 31 formed by aluminum die-casting, a cylindrical portion 32 connected to the elliptic reflector 31, and a condenser lens 33 fitted to the cylindrical portion 32. The elliptic reflector 31 is in the formof a rotary elliptic reflective surface 31a and a bulb 34 is detachably fitted into a bulb fitting hole formed in the center of the elliptic reflector 31, the filament of the bulb 34 being set on the first focal point of the reflective surface 31a. A pair of fitting pieces 31b projecting outward are located at the respective lateral positions of the edge of the - 4 i opening of the elliptic reflector 31, and the cylindrical portion 32 is fixed thereto with mounting screws 35. The cylindrical portion 32 is made by aluminum die-casting and a holder 4 is incorporated with part of the cylindrical portion 32, which construction will be described hereinafter. Moreover, stepped swollen portions 32a directed to the outerdiameter direction of the cylindrical portion 32 are formed in positions opposite to each other on the outer peripheral side of the cylindrical portion 32.
The elliptic reflector 31 is fixed to the back surface side of the swollen portions 32a.
Further, the condenser lens 33 is disposed in the opening of the leading end of the cylindrical portion 32, and an annular mating edge 33a protruding in the outer diameter direction is provided in the outer peripheral portion of the base of the condenser lens 33. An annular retaining ring 36 having a pair of legs 36a is provided in the diametric position and the condenser lens 33 is fixedly supported at the front end of the cylindrical portion 32 by bringing the retaining ring 36 into contact with the front of the mating edge 33a of the condenser lens 33 and the leg portion 36a of the retaining ring 36 is tightened around the front end of the cylindrical portion 32 with a mounting screw 37. Reference numeral 38 denotes a shielding wall integrally formed with the cylindrical portion 32 and provided in proximity of the second focal point of the reflective surface 31a of the elliptic reflector 31. The light distribution pattern of the low beam is formed by shielding part of the light emitted from the filament of the bulb 34 and reflected by the reflective surface. The floodlight type lamp 3 can be made to provide a large quantity of irradiation light even when the area of the floodlight type lamp in front elevation is made smaller than that of the reflector type lamp because the reilective surface 31a is usable for reflecting the light emitted from the bulb 34 without loss and because the condenser lens 33 is usable for irradiation at a desired light distribution angle.
The platelike holder 4 is incorporated with the cylindrical portion of the floodlight type lamp 3. A cutout portion 41 like a substantially semicircular depressed portion is formed in the lower side portion of the holder 4, and three screw-fitting holes 42 are bored in position. A reflector type lamp 5 as the high beam lamp RBL is installed in the area extended from the lower side portion of the holder 4. The reflector type lamp 5 is fitted with a plastic parabolic reflector 51. The parabolic reflector 51 is opened forward so that it is rectangular in front elevation and that its inner surface is formed as a reflective surface 51a having a rotary parabolic surface. Further, a bulb 52 is detachably fitted in a bulb fitting hole formed in the central portion of the parabolic reflector 51, and the filament of the bulb 52 is disposed on the focal point of the reflective surface 51a. A fitting boss 57 is projected in three places on the back surface of the parabolic reflector 51, which is supported by the holder 4 by inserting and screwing mounting screws 58 into the respective screw-f itting holes of the holder 4 forward from the back surface of the holder 4. At this time, the swollen rear end portion of the parabolic reflector 51 has been passed backward through the cutout portion 41.
Further, light-distribution control prisms 21 for obtaining a desired light distribution pattern by refracting the direct light emitted from the bulb 52 and the light reflected from the reflective surface Sla are formed in the back surface area of the front lens 2 located opposite to the edge of the opening of the parabolic reflector 51, whereby the area in which the light-distribution control prisms 21 out of the whole area of the front lens 2 functions as the lens of the reflector type lamp 5. This reflector type lamp 5 is arranged so that the area of the parabolic reflector 51 in front elevation is set greater than that of the floodlight type lamp 3 so as to obtain the desired light distribution pattern and the desired quantity of irradiation light, and particularly the width dimension of the parabolic reflector I 51 is set greater than the width dimension of the floodlight type lamp 3 in the horizontal direction.
The reflector type lamp 6 as the turn-signal lamp TSI, extended over the vertical dimension of each lamp is installed inside an area adjacent to the floodlight type lamp 3 and the reflector type lamp 5. The reflector type lamp 6 is fitted with a reflector 61 formed with a reflective surface 61a having a desired curved surface, and a bulb 62 which is detachable from and placed in the vertical midposition of the reflector 61. Inner lenses 71 are disposed in the front position of the reflector 61 and along the inner surface of the front lens 2. The inner lenses 71 are formed as an extension member 7 simultaneously used as an extension for the floodlight type lamp 3 and the reflector type lamp 5. In other words, the extension member 7 is made of light transmitting plastics and formed with a circular cutout 72 made over a range in which the floodlight type lamp 3 is visually recognizable, and a substantially rectangular cutout 73 made over a range in which the opening of the parabolic reflector 51 in front elevation is also visually recognizable. The extension member 7 is supported with the back surface of the front lens 2 with screws in a plurality of places (not shown). Moreover, the inner lenses 71 including an upper and a lower rectangular light-transmitting section are vertically formed in part of the extension member 7. Around each of the inner lenses 71, there is formed a recessed groove 74 matching the rectangular shape over the whole periphery of the inner lens 71, and the whole surface of the extension member 7 excluding the light transmitting portions of the inner lenses 71 is covered with a black coating film with the recessed grooves 74 as a boundary. Thus, the light emitted from the bulb 62 is reflected from the reflective surface 61a and emitted through the upper and lower inner lenses 71. Consequently, the turn-signal lamp TSL becomes visually recognizable as if it appears to be independent of and adjacent to the floodlight type lamp 3 (the low beam lamp TBL) and the reflector type lamp 5 (the high beam lamp RBL).
on the other hand, there is also provided an aiming mechanism 8 for adjusting optical axes, that is, making an aiming adjustment by vertically and horizontally tilting the floodlight type lamp 3 and the reflector type lamp together with respect to the lamp body 1. In this aiming mechanism 8, a circular support hole 43 is formed in part of the holder 4 incorporated with the cylindrical portion 32 of the floodlight type lamp 3, that is, in an obliquely downward position of the cylindrical portion 32.
Moreover, a pair of rectangular support holes 44 and 45 are respectively formed on vertical and horizontal lines passing through the circular support hole 43. As shown in Fig. 7, the circular support hole 43 and the pair of rectangular support holes 44 and 45 are formed in regions equivalent to the respective apexes of a right triangle in such a way as to surround the floodlight type lamp 3, that is, its cylindrical portion 32 and moreover the hypotenuse of the right triangle is designed to pass the center of the circle of the cylindrical portion 32.
A plastic spherical-body receiving portion 81 is fitted into and supported by the circular support hole 43 of the holder 4, and a spherical recessed portion 81a is opened in the rear portion of the spherical-body receiving portion 81. A spherical body 82a formed integrally with the front end of a pivot shaft 82 projecting toward the inner surface of the lamp body 1 is rotatably fitted into the spherical recessed portion 81a whereby to form a pivotal fulcrum portion C. Plastic aiming nuts 83 and 84 are fitted into and supported by the respective rectangular support holes 44 and 45. Screw portions 85a and 86a at the leading ends of a pair of aiming screws 85 and 86 rotatably supported with the lamp body 1 are screwed into the respective aiming nuts 83 and 84. Thus, a vertical aiming-adjusting portion V and a lateral aiming- adjusting portion H are formed. Head portions 85b and 86b of the respective screws 85 and 86 are passed through the rear surface of the lamp body 1 and projected outward (into the engine room of an automobile), 8 so that each of the aiming screws 85 and 86 can be turned using a tool such as a screwdriver.
In this aiming mechanism 8, since the screw portions 85a and 86a are screwed into the aiming nuts 83 and 84 or unscrewed therefrom when the aiming screws 85 and 86 are turned, the holder 4 supporting the aiming nuts 83 and 84 is tilted with the pivotal fulcrum portion C as a fulcrum. In other words, since the aiming screws 85 and 86 are provided on the horizontal and vertical lines passing the pivotal fulcrum portion C, the holder 4 is tilted vertically and laterally with the horizontal and vertical lines as axes when the aiming screws 85 and 86 are turned and the optical axes of irradiation of the floodlight type lamp 3 and the reflector type lamp 5 can thus be adjusted.
Reference numerals 90 and 91 denote rubber waterproof covers which are fitted to sockets 38 and 53 for holding the bulbs 34 and 52 in order to waterproof the gap between the lamp body 1 and each of the bulb sockets 38 and 53.
in order to assemble the headlamp, the cylindrical portion 32 integral with the holder 4 is first mounted with the condenser lens 33 constituting the floodlight type lamp 3, and the elliptic reflector 31 fitted with the bulb 34. Then the parabolic reflector 51 fitted with the bulb 52 constituting the reflector type lamp 5 is mounted, and the spherical-body receiving portion 81 and the aiming nuts 83 and 84 constituting the aiming mechanism 8 are fitted in so as to form a sub- assembly. Further, a pivot shaft 82 is mounted on the inner surface of the lamp body 1, and the aiming screws 85 and 86 are inserted from behind the lamp body 1. The pivot shaft 82 is fitted into the spherical-body receiving 81 by inserting the sub-assembly from the front of the lamp body 1, and the aiming screws 85 and 86 are screwed into the aiming nuts 83 and 84 to have the sub-assembly supported in the lamp body 1. The extension member 7 is securely inserted from the front of the lamp body 1 after the reflector 61 constituting the turn-signal lamp TSL is mounted in the lamp body 1 with proper means such as screws - 9 :nd then the front lens 2 is fitted so as to cover the opening side of the lamp body 1. Then parts such as the waterproof covers are mounted to complete the assembly of the headlamp HL.
Since the floodlight type lamp 3 as the low beam lamp TBL is disposed above the reflector type lamp 5 as the high beam lamp RBL in the headlamp according to this embodiment of the invention, the triangular or trapezoidal headlamp HL whose upper width dimension is smaller in front elevation can be accomplished. Even in this case, it is possible to secure the quantity of irradiation light required for the headlamp HL as a substantially large quantity of irradiation light is obtainable from the upper floodlight type lamp 3 which is provided with the elliptic reflector 31 and the condenser lens 33, though the area of the floodlight type lamp 3 is small in front elevation. Even when the headlamp HL is partitioned into the upper and lower areas roughly with the center boundary, the quantity of irradiation light required for each of the upper and lower lamps can be satisfied and particularly when one of the lamps is lighted, the external appearance of the headlamp becomes improved.
As the aiming mechanism 8 is arranged so that the pivotal fulcrum portion C, the vertical and lateral aiming-adjusting portions V and H are disposed in positions around the floodlight type lamp 3 with the relatively heavy condenser lens 33 according to the aforementioned embodiment of the invention, the weight of the floodlight type lamp 3 is received by the aiming mechanism 8, whereby the floodlight type lamp 3 and the reflector type lamp 5 can be supported stably in the lamp body 1 since the floodlight type lamp is prevented from tilting forward or backward because of its own weight. Thus, the headlamp HL having stable light- distribution pattern characteristics is obtainable.
As it is only needed to mount the condenser lens 33 and the elliptic reflector 31 onto the cylindrical portion 32 integral with the holder 4 and to fit the parabolic reflector 51 and the component parts of the aiming mechanism 8 to the holder 4 when the - h dlamp is assembled according to the aforementioned embodiment of the invention, these assembled components as sub-assemblies can be integrally built in the lamp body 1 and this facilitates the work of assembling the lamp in comparison with a case where individual parts are assembled successively. The directions of irradiation of the lamps in the floodlight type lamp 3 and the reflector type lamp 5 are made collectively variable by building up the aiming mechanism 8 in the holder 4 integral with the cylindrical portion 32 of the floodlight type lamp 3 according to the aforementioned embodiment of the invention, moreover, it is also possible to decrease the number of parts constituting the aiming mechanism 8 as well as the number of steps of assembling the parts, and the weight of the headlamp.
Although a description has been given of a case where the floodlight type lamp is employed as a low beam lamp and the reflector type lamp as a high beam lamp, it may also be arranged to use the floodlight type lamp as a fog lamp as well as utilizing a bulb having two known filaments for the reflector type lamp whereby to provide a lamp having both functions of low and high beam lamps in combination according to the aforementioned embodiment of the invention. Although an example of arranging the front turn-signal lamp in the lamp body has been described according to the aforementioned embodiment of the invention, moreover, the front turnsignal lamp may be provided independently outside the lamp body. As it is only needed to ins-tall only the floodlight type and reflector type lamps in the lamp body in this case, the freedom of designing the layout of lamps and shapes of a lamp body and a front lens would be enlarged. Further, a material different from the material of the cylindrical portion may be used for the holder.
As set forth above, not only the desired light distribution pattern but the desired quantity of irradiation light can be secured since the headlamp is so constructed as to. place the floodlight type lamp above the reflector type lamp, and the headlamp which is triangular or trapezoidal and whose upper portion is smaller ir idth than the lower portion in front elevation can be accomplished. Even when the relatively heavy floodlight type lamp is located on the upper side, the floodlight type lamp can be supported stably since the aiming mechanism is disposed in positions around the floodlight type lamp. Thus, the headlamp having stable light-distribution pattern characteristics becomes accomplishable.
