Description

  The present invention relates to a vehicular lamp such as an automobile, and more particularly to a vehicular lamp that performs simulated lighting of a lamp using phosphorescence.

  A phosphorescent material is applied to a part of a headlight or a sign lamp of an automobile, and a pseudo-lighting is performed by using the light accumulated in the phosphorescent material (in this case, a state in which the lamp looks as if it is lit) ) Has been proposed. In Patent Document 1, a lamp reflector using an LED (light emitting diode) as a light source is formed of a transparent member, and the transparent member contains a phosphorescent material. When the LED emits light, the phosphorescent material is stored, and the LED does not emit light. Sometimes simulated lighting is performed with light emitted from the phosphorescent material. Further, Patent Document 2 proposes a lamp in which a phosphorescent material is applied to a portion that does not impede light distribution by a lamp component such as a light source, a lens, a reflector, and an extension. The sunlight is stored in the phosphorescent material, and the lamp is quasi-lit using the light emitted from the phosphorescent material when not lit.

Since the technology of Patent Document 1 contains a phosphorescent material in a transparent reflector, it cannot be denied that the reflection efficiency at the reflector is reduced and the illumination effect is reduced. On the other hand, since the technology of Patent Document 2 is formed in a portion where the light distribution material does not hinder the light distribution when the lamp is lit, the light distribution characteristic can be prevented from being deteriorated, but the light storage material is used as much. The area | region to apply | coat is limited and the light emission surface of a phosphorescent material becomes small, and the effect of the pseudo lighting by a phosphorescent material is reduced. Patent Documents 1 and 2 both have a structure in which a phosphorescent material that emits light in a single color is simply applied. Therefore, when the light is emitted, it only exhibits an appearance as a uniform simple color light-emitting surface, and has poor design. There is also a problem.

  An object of the present invention is to provide a vehicular lamp that has improved design on the appearance during pseudo lighting. Another object of the present invention is to provide a vehicular lamp that has improved design without degrading the light distribution characteristics of the lamp, and further has increased the light emitting area on the exterior to improve the visibility of pseudo lighting. Is.

The present invention relates to a vehicle including a reflector-type lamp unit that includes a base plate extending in a horizontal direction and having a light emitting element mounted on one surface thereof, and a reflector disposed on the one surface side of the base plate. The reflector includes a plate-like attachment portion attached to the one surface of the base plate, and a reflector that extends from the attachment portion and reflects light emitted from the light emitting element. A phosphorescent film that includes a reflective surface having a shape and that stores light in a portion of the attachment portion and the base plate close to the light emitting element and that emits the stored light toward the reflective surface. It is characterized by being arranged .

In the present invention, the phosphorescent film is disposed at a position that does not hinder the light distribution formed by the lamp unit. The phosphorescent film is disposed on the attachment portion. Alternatively, the phosphorescent film is disposed on the one surface of the base plate.

In the present invention, preferably, the phosphorescent film includes a plurality of phosphorescent films having different emission colors, a phosphorescent film having a non-uniform luminance distribution, a phosphorescent film having a non-smooth light emitting surface, and a phosphorescent film having a light emitting surface having a desired pattern. It is composed of at least one phosphorescent film.

According to the present invention, in a reflector-type lamp unit configured by a base plate extending in the horizontal direction and mounting a light emitting element, and a reflector, a plate-like attachment portion provided on the reflector is attached to the base plate. In this way, the lamp unit can be configured, and the phosphorescent film is formed on the base plate or the attachment portion, particularly in the vicinity of the light emitting element, so that the phosphorescent film is hardly observed directly from the front of the lamp. Therefore, the light emission area of the phosphorescent film can be increased to improve the visibility during pseudo lighting. Moreover, since the phosphorescent film is disposed at a position that does not hinder the light distribution by the lamp unit, the light distribution characteristics of the lamp are not deteriorated.

Further, according to the present invention, the phosphorescent film disposed in the lamp unit requires a plurality of phosphorescent films having different emission colors, a phosphorescent film having a nonuniform light emission luminance distribution, a phosphorescent film having a non-smooth light emitting surface, and a light emitting surface. Since the lamp unit is in a quasi-lighted state, the light-emitting surface of the light-storage film emits light of different color, non-uniform light emission brightness. In this state, the light emission surface is observed as if the areas of the light emission surfaces are different, the light emission surface emits light in a desired pattern, or a combination thereof. This makes it possible to enhance the design effect of the pseudo lighting as compared with a lamp having a phosphorescent film having the same color and uniform light emission luminance or light emission pattern.

(Embodiment 1)
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view in which a part of the schematic configuration of the lamp according to the first embodiment of the present invention is broken, and FIG. 2 is a longitudinal sectional view taken along line II-II in FIG. This lamp is configured as a headlamp HL of an automobile, and is disposed on the left and right of the front part of the automobile body not shown in the drawing. Although the left and right headlamps are formed symmetrically, the cross-sectional structures are substantially the same. 1 and 2 show an example of a left head lamp. A reflector type lamp unit 2 is built in a lamp housing 1 having a structure in which a transparent cover 12 is attached to a front opening of a lamp body 11. When the unit 2 is turned on, the headlamp HL is turned on. An extension 13 for covering the surrounding area of the lamp unit 2 is provided in the lamp housing 1.

  As shown in a schematic exploded perspective view in FIG. 3, the lamp unit 2 includes a base plate 21 extending in a substantially horizontal direction, and a reflector 22 attached integrally to the lower surface of the base plate 21. ing. The reflector 22 has a configuration in which a plurality of reflector portions 23, here, five reflector portions 23a to 23e are arranged side by side in the left-right direction. The reflector portion 23 is attached to a lower surface of the base plate 21 and is attached to an attachment portion 24 (24a to 24e) made of a rectangular frame plate, and extends from the attachment portion 24 in an inclined state toward the front of the lamp and downward of the lamp. It has the parabolic reflecting surface 25 (25a-25e) made.

  4 is an enlarged longitudinal sectional view of the lamp unit 2 shown in FIG. On the lower surface of the base plate 21, LEDs 26 (26a to 26e in FIG. 3) are mounted as light sources corresponding to the plurality of reflector portions 23 (23a to 23e in FIG. 3). Each LED 26 has a light emitting surface directed downward, and is disposed within the frame of the attachment portion 24 when the reflector 22 is attached to the base plate 21. Each LED 26 emits light toward the lower side of the base plate 21, that is, toward the reflection surface 25 when the LED 26 is supplied with power and emits light. In addition, five phosphorescent films 27 (27a to 27e) are disposed on the lower surface of the base plate 21 so as to be close to the plurality of LEDs 26, respectively. These phosphorescent films 27 are configured as phosphorescent plates in which a phosphorescent material is applied to the surface of a ring-shaped plate material, and are positioned so that the LED 26 is housed in the center hole, and then the lower surface of the attachment portion 24. It is affixed with an adhesive or the like. Details of this phosphorescent film will be described later.

  Each reflecting surface 25 of the plurality of reflector portions 23 is formed as a paraboloid having the corresponding LED 26 as a focal point, and reflects light emitted from the LED 26 toward the front of the lamp as will be described later. The reflecting surface 25 of each reflector unit 23 is basically designed to have substantially the same shape, but the size and shape of each reflecting surface 25 are one to form the required light distribution required for the lamp unit 2. The parts are different. And although illustration is abbreviate | omitted, the light of LED26 reflected toward the lamp front in the reflective surface 25 of each reflector part 23 mutually overlaps in the front area | region of a lamp, and the light distribution which illuminates the required area | region ahead of a motor vehicle Can be obtained.

  The phosphorescent film 27 is formed as a phosphorescent plate in which a phosphorescent material that accumulates or emits predetermined color light is applied to the surface of a generally annular plate having a center hole as described above. Since the back surface is bonded to the lower surface of the attachment portion 24, the phosphorescent surface, that is, the light emitting surface is directed downward. Further, the LEDs 26 are bonded so as to be disposed in the center hole of the phosphorescent plate 27, and the annular phosphorescent plate 27 extends around the LEDs 26. Since various materials have already been proposed for the phosphorescent plate 27, a suitable phosphorescent material can be selected in consideration of durability when used for a vehicle lamp. In addition, five types of phosphorescent materials having different emission colors are selected for the plurality of phosphorescent plates 27 provided in each reflector portion 23. Here, the five phosphorescent plates 27a to 27e are set with phosphorescent materials of yellow green color, blue color, purple color, red color, and yellow color in this order.

  According to the lamp unit 2 of the first embodiment, when the headlamp HL is turned on, that is, when the lamp unit 2 is turned on, as shown by a solid line in FIG. Are reflected toward the front by the reflecting surface 25 of the corresponding reflector portion 23, pass through the transparent cover 12 of the lamp housing 1, and irradiate the front area of the automobile. As described above, the light reflected by the plurality of reflectors 23 is superimposed to obtain a required light distribution. Further, at this time, the light distribution characteristic is not deteriorated because the light for the light distribution is not blocked or dimmed by the phosphorescent plate 27. When the lamp unit 2 is turned on, as shown by a broken line in FIG. 4, a part of the light emitted from the LED 26 or a part of the light reflected by the reflecting surface 25 is projected on each phosphorescent plate 27, Done.

  When the lamp unit 2 is turned off from the lighting state, the illumination by the light emitted from the LED 26 is terminated, but the phosphorescent plate 27 that has been stored at the time of lighting is emitted, and the light is reflected on the reflecting surface of each reflector unit 23. It is reflected by 25 and irradiated forward. As a result, when the headlamp HL is observed from the front of the automobile, the respective reflecting surfaces 25 of the reflector portions 23 (23a to 23e) are illuminated brightly as schematically shown in FIG. It looks as if it is lit, and the headlamp HL is in a pseudo-lit state. This pseudo-lighting makes it possible to visually recognize the area immediately before the host vehicle, and the presence of the host vehicle is recognized by other vehicles and pedestrians, which is preferable from the viewpoint of traffic safety.

  In this pseudo-lighting, each phosphorescent plate 27 of each reflex unit 23 emits light with each light emission color, that is, each color light of yellow green color, blue color, purple color, red color, and yellow color. Accordingly, when the lamp unit 2 or the headlamp HL is viewed from the front of the lamp, the reflecting surfaces 25 (25a to 25e) of the reflector portions 23 (23a to 23e) shown in FIG. The lamp unit 2 is observed in a state of being colored in red, yellow, and yellow, so that the entire lamp unit 2 is in a light-emitting state with rich colors, and the design of the lamp during pseudo lighting is improved.

  In the first embodiment, since the phosphorescent plates 27 are disposed close to the LEDs 26, these phosphorescent plates 27 are disposed at the focal position of the reflecting surface 25 of each reflector portion 23 or in the vicinity thereof. Therefore, the light emitted from the phosphorescent plate 27 is reflected forward on the reflecting surface 25 of the reflector portion 23 in the same manner as the light emitted from the LED 26. As a result, the light from the phosphorescent plate 27 is emitted toward a wide area in front of the automobile with the same light distribution as when the lamp unit 2 is turned on, and the headlamp HL is simulated from the wide area in front of the automobile. It becomes possible to improve the visibility of lighting.

  Furthermore, in the first embodiment, the phosphorescent plate 27 is disposed at a position on the lower surface side of the base plate 21 of the lamp unit 2, and this position is not exposed in front of the headlamp HL. The appearance of the headlamp HL due to the fact that the phosphorescent plate 27 is exposed through the transparent cover 12 when not lit is not deteriorated.

  In the first embodiment, a phosphorescent film may be formed by applying a phosphorescent material to the surface of the extension 13. Also in this case, the phosphorescent materials having different emission colors are appropriately divided and formed. In this way, a part of the light emitted toward the front of the vehicle when the lamp unit 2 is turned on is reflected by the transparent cover 12 and projected onto the surface of the extension 12, so that the coating formed on the surface is applied. The phosphorescent film is subjected to phosphorescence. Therefore, when the lamp unit 2 is turned off, the light emitted from the respective phosphorescent films from the surface of the extension 13 is irradiated forward through the transparent cover 12, and pseudo lighting with rich colors and high design properties is observed. It will be.

(Embodiment 2)
FIG. 5 is a longitudinal sectional view of a vehicular lamp according to a second embodiment of the present invention. As in the first embodiment, the present invention is applied to a headlamp of an automobile. Here, a projector-type lamp unit 3 of the second embodiment is housed in a lamp housing (not shown). The projector-type lamp unit 3 is already known and will not be described in detail. However, the projector-type lamp unit 3 includes a light source 31, a reflector 32, an irradiation lens 33, and a shade 34. Light emitted from the light source 31 is reflected by the reflector 32. Then, the light is condensed once, and part of light is shielded by the shade 34, and then light that is not shielded is irradiated forward through the irradiation lens 33 with a required light distribution.

  The light source 31 is composed of an LED, and the reflector 32 is composed of a spheroidal reflecting mirror having the LED 31 as a first focal point F1. The rear focal point of the irradiation lens 33 is substantially coincident with the second focal point F2 of the reflector. In other words, the shade 34 is disposed in the vicinity of the second focal point F2, that is, the rear focal point. Yes. The shade 34 is formed integrally with a holder 35 for supporting the irradiation lens 33 on the reflector 32, and shields ambient light that does not contribute to light distribution and passes through a region below the rear focal point. And it is provided to shield the light that illuminates the oncoming vehicle. Therefore, the shade 34 is configured as a substantially semi-circular shade plate that is erected along a region below the rear focal point in the circular opening of the reflector 32.

  A phosphorescent material is applied to the front surface of the shade plate 34, and a phosphorescent film 36 is formed by the phosphorescent material. In the second embodiment, one kind of phosphorescent material having a predetermined emission color is used as the phosphorescent material, and this phosphorescent material is applied to the front surface of the shade plate 34 in a required form. In this embodiment, a plurality of different forms are prepared, and the plurality of forms can be arbitrarily selected and applied. Here, only a part of the form will be described. However, a non-planar type in which the surface of the phosphorescent film 36 is formed in a curved surface and an uneven surface and a pattern type in which the phosphorescent film is formed in a desired pattern (pattern) are included.

  Here, the non-planar type will be described in which the surface of the phosphorescent film is formed in a convex shape, a concave shape, or an uneven shape. FIG. 6 is a cross-sectional view of the non-planar type phosphorescent film 36, and is a schematic sectional view when the shade plate 34 and the phosphorescent film 36 of FIG. 5 are cut along the line VI-VI. In FIG. 6A1, the front surface of the shade plate 34 is formed in a convex curved surface, and the surface of the phosphorescent film 36 is also formed in a convex curved surface. In FIG. 6B1, the front surface of the shade plate 34 is formed in a concave curved surface, and the phosphorescent film 36 is also formed in a concave curved surface. 6 (c1) shows that the front surface of the shade plate 34 is partitioned into, for example, a grid shape, and each partition is formed on a fine tapered (triangular) uneven surface, and the surface of the phosphorescent film 36 is also finely tapered. Formed on the surface. In FIG. 6D1, the front surface of the shade plate 34 is formed on a rough surface having irregular fine irregularities, and the surface of the phosphorescent film 36 is also formed on a fine irregular surface.

  The pattern type is a pattern in which the phosphorescent film 36 is formed into a required pattern (pattern). FIG. 7 is a view showing a pattern of the phosphorescent film 36 when the shade plate 34 is viewed from the front of the lamp. When viewed from the front of the lamp, the shade plate 34 is generally in the shape of a semi-circular upper chord, and in FIG. 7A, a phosphorescent material is applied to the front surface of the shade plate 34 in the form of vertical stripes to form a phosphorescent film 36. Yes. In FIG. 7B, the phosphorescent material is applied in a horizontal stripe shape to form a phosphorescent film 36, and in FIG. 7C, the phosphorescent material is applied in a downward arc stripe shape to form the phosphorescent film 36. .

  In the second embodiment, when the lamp unit 3 is turned on, the light emitted from the emitted LED 31 is reflected by the reflector 32 and collected at the second focal point F2, where a part of the light is blocked by the shade plate 34. Is done. Light that is not shielded is incident on the irradiation lens 33 in a diffused state, is refracted and transmitted there, and is irradiated to a front area of the automobile with a required light distribution. Since the phosphorescent film 36 is disposed on the front surface of the shade plate 34, the phosphorescent film 36 does not affect the light distribution. At this time, a part of the light incident on the irradiation lens 33 is reflected by the irradiation lens 33 and projected onto the front surface of the shade plate 34, that is, the light storage film 36 formed on the front surface, and the light storage film 36 stores the light. Is done.

  When the lamp unit 3 is turned off from the lighting state, the illumination by the light emitted from the LED 31 is terminated, but the light storage film 36 stored at the time of lighting is emitted, and the light is transmitted through the irradiation lens 33. Irradiated forward. Thereby, this irradiation light can be observed from the front of the automobile, and the lamp unit 3 is in a pseudo-lit state. At this time, when the light emitting surface of the phosphorescent film 36 is observed from the front of the irradiation lens 33, the light emitting surface is observed as a light emitting surface that is turned upside down.

  At the time of this pseudo lighting, the non-planar type phosphorescent film shown in FIG. 6 emits light in various forms as compared with the case where the phosphorescent film is formed in a plane. In the light storage film having a convex curved surface in FIG. 6 (a1), light emission is diffused and the light emission surface is enlarged as shown in FIG. 6 (a2). In the light storage film having a concave curved surface in FIG. 6 (b1), the light emission is condensed as shown in FIG. 6 (b2) to form a light emitting surface having a high brightness but a narrow light emitting surface. In the phosphorescent film in which the tapered uneven surface of FIG. 6 (c1) is formed in a grid shape, the light emitting surface is arranged in a grid shape as shown in FIG. 6 (c2). In the rough phosphorescent film of FIG. 6 (d1), the light emission surface is randomly generated as shown in FIG. 6 (d2). Thereby, it becomes an accentuated light emitting surface having a luminance distribution as compared with a phosphorescent film having uniform light emission luminance, and the design effect of the lamp unit 3 at the time of pseudo lighting is enhanced.

  Moreover, the light emitted from the pattern-type phosphorescent film becomes a light-emitting surface obtained by inverting the pattern shown in each drawing of FIG. Although illustration is omitted, the vertical stripe-shaped phosphorescent film of FIG. 7A emits light in a vertical stripe pattern corresponding to the vertical stripe. In the horizontal stripe-shaped phosphorescent film of FIG. 7B, light is emitted in a horizontal stripe pattern corresponding to the horizontal stripe. In the arc-striped phosphorescent film of FIG. 7C, light is emitted in an arc-striped pattern corresponding to the arc-striped pattern. Thereby, the luminance of the light emitting surface becomes a luminance distribution according to the pattern, and the light emitting surface is accented and the design effect is enhanced.

  Here, when forming a pattern-type phosphorescent film, it is not limited to a structure in which a phosphorescent material is simply applied in a pattern, and a configuration having a cross-section shown in FIG. 8 may be applied. FIG. 8 is a cross-sectional view of the same portion as FIG. In FIG. 8A, a groove having a required pattern is formed on the front surface of the shade plate 34, and a phosphorescent film 36 is formed by applying or filling a phosphorescent material into the groove. In FIG. 8B, a phosphorescent material 36 is uniformly applied to the front surface of the shade plate 34 to form a phosphorescent film 36. A mask of a non-translucent material having a required pattern is formed on the surface of the phosphorescent film 36. Pattern.

  It is also possible to form a pattern by making the distribution of light emission luminance on the light emitting surface non-uniform. That is, as shown in FIG. 8C, the phosphorescent film 36 is formed by continuously changing the film thickness of the phosphorescent material applied to the front surface of the shade plate 34. Alternatively, as shown in FIG. 8D, the phosphorescent film 36 is formed by changing the film thickness of the phosphorescent material stepwise. Or although illustration is abbreviate | omitted, instead of changing the film thickness of a luminous film, you may make it apply | coat to the state which put in order the luminous material from which luminous characteristics (accumulated light quantity per unit area and emitted light amount) differ. In this way, the amount of accumulated light in each part of the light emitting surface can be made different, the light emission luminance can be made different, and a light emitting surface with gradation can be formed, and the design effect at the time of pseudo lighting can be enhanced.

  In the second embodiment, the phosphorescent film 36 is formed on the front surface of the shade plate 34, and the shade plate 34 is an LED 31 as a light source disposed at the second focus F2 of the reflector 32, in other words, at the first focus F1. Are located close to each other at an optically equivalent position. Therefore, the light emitted from the phosphorescent film 36 is irradiated toward a wide area in front of the automobile by the irradiation lens 33 in the same manner as the light emitted from the LED 31. Thereby, it becomes possible to improve the visibility of pseudo lighting from a wide area in front of the automobile.

  Also in the phosphorescent film of the second embodiment, by forming a desired pattern by combining phosphorescent materials having different emission colors as in the first embodiment, various forms of emission color, emission luminance distribution, and emission pattern at the time of pseudo lighting are obtained. As a result, it is possible to further enhance the design effect. In the second embodiment, the phosphorescent film 36 is disposed at a position where it can be observed from the outside through the irradiation lens 33. However, the phosphorescent film 36 is difficult to see from the front of the lamp due to total reflection on the front surface of the irradiation lens 33. Therefore, the appearance of the lamp when the lamp is not lit is hardly reduced by forming the phosphorescent film 36.

  The present invention is not limited to the configurations of the first and second embodiments. For example, in Embodiment 1, a phosphorescent film may be formed by applying a phosphorescent material to the lower surface of the base plate of the lamp unit. In this case, the phosphorescent film may be formed in a required pattern, and the patterned light emission may be reflected by the reflector portion and lighted in a pseudo manner. Moreover, in Embodiment 2, you may stick the phosphorescent board which apply | coated the phosphorescent material previously to the front surface of a shade. In this case, a plurality of phosphorescent plates coated with phosphorescent materials having different emission colors may be arranged side by side.

  Regardless of the configuration of the first and second embodiments, the phosphorescent film according to the present invention can also be formed on other optical members constituting the lamp unit. For example, a phosphorescent film may be formed on part of the light transmission surface of the irradiation lens and part of the reflection surface of the reflector. Even in this case, the present invention can be achieved by forming the phosphorescent film with a phosphorescent film of different emission colors or forming it in a desired pattern. However, in these cases, it is important to set the formation region and type of the phosphorescent film so that the predetermined light distribution required for the lamp unit is not hindered. Furthermore, in the case of a phosphorescent material with high light transmittance, it is possible to form a phosphorescent film so as to cover the lens surface and the light source.

  In addition, the phosphorescent film in the present invention may be configured not only to store light emitted from the light source of the lamp, but also as a phosphorescent film that stores sunlight using daylight. In this case, a phosphorescent film can be formed on the surface of a constituent member such as an extension or a lamp unit cover provided in the lamp housing. Furthermore, a phosphorescent film may be formed on the inner surface of the lamp housing.

  The present invention can be applied to a vehicle lamp in which a phosphorescent material for performing pseudo lighting is provided on a lamp housing or a lamp unit.
