Description
Technical Field
The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp externally mounted on a vehicle such as a truck, a taxi, or a bus.
Background
Conventionally, a side marker lamp has been known as a vehicle lamp externally mounted on a truck or the like. In general, a side marker lamp includes a housing, a light source unit, and an outer lens in a shell shape, and has a function of a marker lamp that is lighted at night to indicate a vehicle width.
Therefore, in the side marker lamp of patent document 1, although the annular reflector is provided near the housing, the outer lens is a general transparent or functional color lens, and there is a problem that the appearance does not change during the non-lighting time in the daytime.

Disclosure of Invention
Problems to be solved by the invention
Therefore, it is desired to develop a new vehicle lamp that ensures visibility at night when lit and has an appearance different from that of a general outer lens when unlit during the day.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle lamp having a completely new design.
Means for solving the problems
In order to achieve the above object, a vehicle lamp according to an aspect of the present invention includes: a light source; a housing provided with the light source therein; and an outer lens that forms a lamp chamber together with the housing, and has a semi-transparent metal layer on an entire outer surface of the outer lens, at least at a portion exposed to the outside of the vehicle body.
In the above aspect, since the semi-transparent metal layer (semi-transparent mirror deposited film) is formed on the outer surface of the outer lens, the outer lens gives a feeling like a mirror surface decoration when not lit, and functions as an illumination when lit, thereby providing an unpredictability as an appearance design when lit. Further, since the semi-light-transmitting metal layer is directly formed on the outer surface of the outer lens, an impressive appearance such as plating, which is not achieved by conventional vehicle lamps, can be realized. In addition, since a protective cover is not further provided, the cost can be reduced.
In the above aspect, it is preferable that the outer lens has a shape that the lamp chamber protrudes forward, and the outer lens is attached so as to be exposed from the vehicle body.
With this configuration, the illumination light from another vehicle is reflected at the time of non-lighting at night, and therefore visibility can be ensured even at the time of non-lighting.
In addition to the above, it is preferable that an optical step is formed on an inner surface of the outer lens.
With this configuration, the appearance of the mirror surface is provided when the lighting unit is not lit, and the texture formed by the optical steps can be visually recognized only when the lighting unit is lit.
In addition to the above aspect, it is preferable that the outer lens is made of a colored transparent material.
With this configuration, the liquid crystal display device has a mirror (metallic) appearance when not lit, and emits colored light when lit, so that the appearance changes greatly, giving a brand new impression to consumers.
In addition to the above aspect, it is preferable that the outer lens includes the semi-light-transmitting metal layer on an entire outer surface.
With this configuration, the entire lamp has an integral mirror surface appearance when not lit, and thus, at first glance, the lamp does not look like a lamp and can give a more brand new impression.
Effects of the invention
According to the vehicle lamp of the above aspect, a vehicle lamp having a completely new design can be provided.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings showing examples. The embodiments described below are not intended to limit the invention but to exemplify the invention, and all of the features and combinations described in the embodiments are not necessarily essential contents of the invention. The same components and members shown in the drawings are given the same names, and redundant description thereof is omitted. In the cross-sectional view, the members seen inside the cross-section are appropriately omitted for convenience of explanation.
In addition, the scale and shape of each portion shown in the drawings are set as appropriate for ease of explanation, and are not to be construed as limiting unless otherwise specified.
(example 1)
The present invention is applied to a side marker lamp of a truck 2 as a vehicle lamp 100 according to embodiment 1. As shown in fig. 1, the vehicle lamp 100 is attached to both sides (only the left side is shown) of the outside of the truck 2 via the attachment plate 3 so as to be exposed from the vehicle body. Alternatively, the mounting member may be directly attached to the vehicle body.
As shown in fig. 2 to 4, the vehicle lamp 100 includes an outer lens 10, a light source unit 20, and a housing 30.
The outer lens 10 is made of, for example, yellow transparent resin. As a material of the outer lens 10, a transparent resin such as colorless or colored acrylic resin (PMMA) or polycarbonate is preferably used. Further, as a material of the outer lens 10, a colorless or colored light-transmitting resin may be used.
The outer lens 10 has a shell shape protruding forward from the housing 30 and opening rearward.
The case 30 is made of an opaque resin such as polypropylene or polyethylene, and has a disk shape having a wall portion on the outer periphery. The lamp chamber of the vehicle lamp 100 is defined by the housing 30 closing the opening of the outer lens 10. As a result, the lamp chamber has a shape protruding forward.
As shown in fig. 2, the housing 30 has a disk shape having a diameter equal to the outer diameter of the opening of the outer lens 10, and has an outer peripheral wall 30a extending in the front-rear direction at the outer periphery. Ribs 31 extending in the front-rear direction are formed in a spider-web shape in the center of the housing 30 to reinforce the strength of the housing 30.
In addition, a hole 37 through which the wiring harness 34 passes is opened in the center of the housing 30. Further, two right and left screw holes 35 through which mounting screws 26 described later are inserted are opened so as to be opposed to each other in the radial direction at positions slightly inward of the outer peripheral portion of the housing 30.
The light source unit 20 is configured by mounting a substrate 22 on a disk-shaped base 21. On the substrate 22, LED (light emitting diode) light sources 23 and resistors 24 are mounted alternately every four at equal intervals in the circumferential direction, and are connected by wires 25. A wiring lead 34 is attached to the center of the base 21 via a wiring holding portion 33, and the wiring 25 is connected to the wiring lead 34 at the center of the base 21.
Screw holes 26a into which mounting screws 26 (threads are omitted in the figure) are inserted are provided at both left and right end portions of the base 21.
The light source unit 20 fixes the mounting screw 26 to the housing 30 by a nut 27 with a washer. Instead of the nut 27 with washer, a separate nut and washer may be used. The outer lens 10 and the housing 30 are bonded together by ultrasonic welding.
The vehicle lamp 100 is normally configured to be externally mounted on the truck 2 via the mounting plate 3 in a state where the housing 30, the light source unit 20, and the outer lens 10 are assembled together and the nut 36 with a washer is screwed and fixed to the mounting screw 26. Instead of the nut 36 with washer, a separate nut and washer may be used.
In general, the lower end of the mounting plate 3 is formed in a semicircular shape extending along the lower portion of the housing, and the upper end of a metal plate having a width substantially equal to the width of the housing 30 is bent at a right angle. Two mounting holes 3a are formed in the vertical surface of the mounting plate 3 at positions corresponding to the mounting screws 26, and an opening 3b through which the wiring harness 34 passes is formed between the mounting holes 3 a. Further, two mounting holes 3c for mounting the truck 2 are formed in the upper surface of the mounting plate 3.
The vehicle lamp 100 is attached to the attachment plate 3 by inserting the wiring harness 34 through the opening 3b, and then inserting the attachment screws 26 through the attachment holes 3a and tightening the nuts 36 with washers. Then, the vehicle lamp 100 is screwed to the truck 2 through the mounting hole 3c in a state of being mounted on the mounting plate 3.
As shown in fig. 4, a semi-transparent metal layer 12 that reflects a part of incident light and transmits a part of the incident light is directly formed on the outer surface (front surface) of the outer lens 10. The semi-light-transmitting metal layer 12 is a so-called semi-mirror vapor deposited film, and aluminum, silver, titanium, gold, or the like can be used as a metal material.
The transmittance of the semi-light-transmitting metal layer 12 can be arbitrarily set within the following range: the mirror surface is formed when the lamp 100 is not lit, making it difficult to visually recognize the inside of the lamp from the outside, and the mirror surface transmits a required amount of light when the lamp is lit. In view of the balance between the light transmittance and the concealing property, the range of 5% to 60% is preferable, and about 15% is particularly preferable.
Further, on the surface of the semi-light-transmitting metal layer 12, for example, silicon dioxide (SiO) may be formed to prevent generation of defects2) And the like as a protective film for a plating or vapor deposition film.
The surface of the outer peripheral wall 30a of the case 30 is subjected to surface treatment of a metallic tone similar to the color tone of the semi-light-transmitting metal layer 12 by plating or metal coating. In this way, the entire lamp has an integrally metallic mirror surface appearance when not lit, contributing to a brand new impression without giving the lamp an impression.
Next, an operation of the vehicle lamp 100 will be described. As shown in the left diagram of fig. 5, when the lighting is off, light from the outside is reflected by the semi-light-transmissive metal layer 12, and the mirror surface appearance is obtained.
On the other hand, at the time of lighting, light entering the optical step 14 among the light from the LED light source 23 is diffused in the optical step 14, passes through the semi-light-transmitting metal layer 12, and is irradiated toward the front of the lamp. The light incident on the optical step 13 is diffused in the circumferential direction of the lamp at the optical step 13, passes through the semi-light-transmitting metal layer 12, and is irradiated in the vehicle longitudinal direction. As a result, as shown in the right drawing of fig. 5, the light is emitted while reflecting the textures of the optical steps 13 and 14, and has an appearance that follows the function of a marker lamp for displaying a predetermined light distribution pattern.
Thus, according to the above configuration, it is possible to provide a vehicle lamp having a completely new appearance such that the mirror surface appearance is displayed when not lit and the appearance following the function appears when lit. The vehicle lamp according to the present embodiment has a mirror surface appearance as a whole when not lit, and therefore is not conspicuous as a lamp during daytime when it is turned off. In particular, drivers of large vehicles such as trucks prefer to use a decorative member finished by metal plating having a mirror surface appearance, and can exhibit an aesthetic appearance consistent with such a decorative member.
In the vehicle lamp 100 according to the embodiment, the semi-light-transmitting metal layer 12 is formed on the surface of the outer lens 10 by direct vapor deposition. Therefore, for example, a transparent cover made of resin is not provided further outside the vapor-deposited layer, and therefore, an unprecedented appearance can be provided as a lamp such as a so-called finish plating. Further, since it is not necessary to provide a resin protective cover or the like, the number of parts can be reduced, and the manufacturing cost can be suppressed.
Further, at night, even when not lit, the vehicle lamp 100 reflects light from the outside such as headlights and streetlights of other vehicles, and thus can ensure a certain visibility. In this case, the translucent metal layer 12 is formed entirely in the portion exposed to the outside of the vehicle, and therefore, no blind spot is formed. In particular, the outer lens 10 is advantageous because it has a shape in which the lamp housing projects forward and is exposed from the vehicle body. When applied to a side marker lamp like the vehicle lamp 100, the vehicle width can be easily recognized and an accident can be prevented even when the vehicle lamp 100 is turned off to park/stop.
As described above, the transmittance of the semi-light-transmissive metal layer 12 can be arbitrarily set within the following range: the mirror surface is formed when the vehicle lamp 100 is not lit, making it difficult for the interior of the vehicle lamp 100 to be visually recognized from the outside, and the mirror surface transmits a required amount of light as a marker lamp when lit. In view of the balance between the light transmittance and the concealing property, the range of 5% to 60% is preferable, and about 15% is particularly preferable. This is because, if the range is such, the internal structure is not normally visible under natural light at the time of non-lighting, and the unpredictability of the change in the external appearance can be secured.
The optical steps 13 and 14 applied to the inner surface of the outer lens 10 are not essential, and the function as a marker lamp may be ensured by controlling the light distribution by using another method such as a reflector or an inner lens. However, by forming the optical step, the lamp itself can exhibit a grain formed in accordance with the optical step at the time of lighting, and thus the impression of appearance change can be enhanced.
As described above, although a colored or colorless, transparent or translucent resin can be used as the material of the outer lens 10, the use of a colored transparent resin is particularly advantageous because the change between the appearance of a metallic color when not lit and the appearance when lit is significant.
(example 2)
As the vehicular lamp 200 according to embodiment 2, the present invention is applied to a decorative lamp externally attached to a vehicle such as a taxi. As shown in fig. 6, the vehicle lamp 200 is attached to a bumper of the vehicle 5 in a bilaterally symmetrical manner, is used decoratively, and has a function of a marker lamp that improves visibility of the vehicle 5.
As shown in fig. 7 to 9, the vehicle lamp 200 includes an outer lens 210, a light source unit 220, and a housing 230.
In addition, the vehicle lamp 200 has a laterally long rod shape with both ends tapered in a front view angle.
The outer lens 210 has a shape that follows the overall shape of the vehicle lamp 200 in a front view, and has a box-like shape that protrudes forward and opens rearward. As a result, the lamp chamber is formed in a shape protruding forward from the housing. In this example, the outer lens 210 is made of a colorless transparent resin. The material of the outer lens 210 can be selected from the same materials as those of the outer lens 10.
The housing 230 is made of an opaque resin such as polypropylene or polyethylene, and has a shape matching the opening of the outer lens 210. The lamp chamber of the vehicle lamp 200 is defined by closing the opening of the outer lens 210 with the housing 230.
Screw holes 235 through which the light source mounting screws 226 are inserted are formed near both ends of the housing 230. A through hole 237 through which a wiring lead (not shown) is inserted is formed in the center of the housing 230. Screw holes 238 for screwing mounting screws 205 mounted on the mounting plate 203 are provided on the rear surface of the intermediate portion between the through hole 237 and the screw holes 235 on both sides.
The light source unit 220 includes a substrate 221 having a shape corresponding to the front view shape of the lamp, and a plurality of (20 in the illustrated example) LED light sources 223 are arranged on the substrate 221 at equal intervals in a row in the left-right direction. Further, through holes 227 through which light source mounting screws 226 are inserted are formed at both end portions of the substrate 221.
The vehicle lamp 200 is generally distributed in a state where the housing 230, the light source unit 220, and the outer lens 210 are assembled together.
The vehicle lamp 200 is attached to the vehicle 5 via an attachment plate 203. Specifically, the mounting plate 203 is screwed by inserting the mounting screw 205 into the mounting hole 203a of the mounting plate 203, and then the mounting plate 203 is screwed by the body mounting screw 206.
As shown in fig. 7 (B) and 8, a semi-translucent metal layer 212 similar to the semi-translucent metal layer 12 of the vehicle lamp 100 is formed on the entire surface of the outer lens 210. As shown in fig. 7 (a) and (B), a plurality of optical steps 213 extending in a wavy line shape in the left-right direction are formed in parallel on the inner surface of the outer lens. In fig. 7 (a), although the optical step 213 is indicated by a broken line, the optical step 213 does not appear when the lamp is not lit.
As a result, as shown in the upper diagram of fig. 10, when the lighting is off, light from the outside is reflected by the semi-transparent metal layer 212, and the appearance of a mirror surface appears.
On the other hand, at the time of lighting, as shown in the lower diagram of fig. 10, light from the LED light source 223 enters the optical step 213, diffuses, and is irradiated forward through the semi-light-transmitting metal layer 212, so that the appearance is provided as a marker lamp that emits light reflecting the texture of the optical step 213.
As described above, the same effects as those of the vehicle lamp 100 can be obtained also in the vehicle lamp 200 having a different shape from embodiment 1.
While the preferred embodiments of the present invention have been described above, the above-described embodiments are examples of the present invention, and they can be combined based on the knowledge of those skilled in the art, and such a mode is also included in the scope of the present invention.
In the above-described embodiments, the example in which the present invention is applied to the side marker lamp and the decorative lamp has been described, but the present invention is not limited to this, and can be widely applied to various vehicle lamps such as a headlamp, an outline marker lamp, a tail lamp, a side turn signal lamp, a stop lamp, a daytime running lamp, a turn signal lamp, a hazard lamp, a position lamp, a backup lamp, and a fog lamp, as far as the law permits.
In the above-described embodiment, the semi-light-transmitting metal layers 12 and 212 are provided on the entire outer lens, but the semi-light-transmitting metal layers 12 and 212 may be formed at least on the entire portion exposed to the outside of the vehicle, and when the outer lens extends to a portion not exposed to the outside of the vehicle, the semi-light-transmitting metal layer 212 is not necessarily formed on the entire surface of the outer lens.
