Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that since light distribution characteristics are formed by lens cut widely used for a fisheye lens and Fresnel lens to be applied to an outer lens in the case of a conventional tail lamp or the like, there is nothing new in appearance in each type of vehicle and assertion of individuality was difficult. <P>SOLUTION: This is a lighting fixture 1 composed of a light emitting part 3a in which light is irradiated from at least one light source 2, a first reflecting plate 4 directed from the light emitting part to a light emitting direction and mounted, and second reflecting plates 5U, 5D directed from a side part opposed to the light source to the same direction as that of the first reflecting plate and mounted open in a nearly V shape. A plurality of small reflecting plates to reflect light from the light emitting part to a direction of the second reflecting plate are installed at front and rear faces of the first reflecting plate, and since these three reflecting plates are made to be the lighting fixtures covered by the outer lens, unconventionally novel appearance is enabled to solve the problems. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a lamp called a tail lamp, a stop lamp, etc., which is employed for a vehicle or the like and is used, for example, to notify the behavior of the own vehicle to a following vehicle, a pedestrian or the like.

  FIG. 6 shows an example of the configuration of a conventional lamp 90 of this type, and the lamp 90 is provided with a reflecting mirror 91 such as a rotating paraboloid, and is placed at the focal position of the reflecting mirror 91. The light from the light source 92 is reflected as a parallel light beam in a direction intended for irradiation.

Further, an outer lens 93 is provided on the reflecting direction side of the reflecting mirror 91 so as to cover the reflecting mirror 91, and the parallel rays from the reflecting mirror 91 are transmitted in the irradiation direction. However, since the irradiation width is narrow and the behavior of the own vehicle cannot be announced in a wide range if the parallel rays from the reflecting mirror 91 remain as they are, the outer lens 93 is provided with a fish-eye lens cut 93a. By appropriately diffusing the parallel light rays from 91, the purpose of the lamp 90 can be achieved as a light distribution characteristic visible from a wide range.

  However, in the lamp 90 having the above-described conventional configuration, the surface on which the uneven fisheye lens cut 93a is applied is directed toward the reflecting mirror 91 for the purpose of preventing adhesion of dust and the like, such as in the daytime. When it is not lit, the surface of the outer lens 93 from the following vehicle appears as a flat surface, and the difference in design is not obvious when viewed from the following vehicle. For example, it is difficult to express the difference in vehicle case both day and night Was causing the problem.

  In addition, even when the lamp is lit, the joint line 43b between the fish-eye lens cuts 93a applied inward is only seen as a cross-shaped pattern or a hexagonal honeycomb-shaped pattern, and it still changes to the following cars. Only a flat impression without glare was given, and the novelty was poor.

  Further, in the conventional lamp 90 described above, in order to make the entire surface of the outer lens 93 emit light with uniform brightness, the reflecting mirror 91 having the same size as the outer lens 93 must be provided. Inevitably, the reflector 91 is inevitably deep. Therefore, the reflection mirror 91 must be embedded in the vehicle body such as a trunk room for installation, and by providing an opening in the vehicle body, the number of processing steps for waterproofing is increased, and the storage capacity of the trunk room is impaired. There are also problems.

  The present invention provides, as specific means for solving the above-described conventional problems, a light emitting portion that is irradiated with light from at least one light source, and a first reflector that is attached from the light emitting portion toward the light emitting direction. And a pair of second reflectors mounted in a substantially V shape in the same direction as the first reflector plate from opposite sides of the light source, the lamp of the lamp One reflector is provided with a plurality of small reflectors on the front and back surfaces that reflect the light from the light emitting portion in the direction of the second reflector, and the light reflected by the second reflector is By providing a lamp characterized by irradiating light in the direction of irradiation of this lamp, and these three reflectors being covered with an outer lens, a lamp that has an unprecedented appearance. As well as simplification of mounting to the car body. It is intended to solve the problem as ability.

  According to the present invention, the light from the light emitting unit is reflected in the direction of the second reflecting plate by the cut and raised small reflecting plate provided on the first reflecting plate, and the second reflecting plate is used. By using a lamp configured to reflect in the irradiation direction, the conventional monotonous light emission state is eliminated and the problem is solved as a lamp having a novel design in which the outer lens surface emits light randomly.

  Below, this invention is demonstrated in detail based on embodiment shown in a figure. What is shown by the code | symbol 1 in FIG. 1 is the lamp | ramp which concerns on this invention, This lamp | ramp 1 is divided roughly into the light source box 3 made into the box shape etc. in order to accommodate light sources 2, such as an LED lamp, and a 1st reflecting plate. 4 and a pair of second reflecting plates 5U, 5D that open in the irradiation direction at a predetermined angle, and cover the light source box 3, the first reflecting plate 4, and the second reflecting plates 5U, 5D from the front. The outer lens 6 is comprised.

  The light source box 3 has, for example, an elongated box shape, and both ends on the single side and three surfaces on the long side are formed of an opaque member, and the remaining one surface is formed of a transparent member such as a transparent resin as the light emitting portion 3a. Yes. A light source 2 such as an LED lamp is housed in the light source box 3 in a state where wiring is performed on the circuit board 2a and blinking can be freely performed from the outside.

  Further, from the light emitting portion 3a of the light source box 3, a first reflecting plate 4 formed in a plate shape with an opaque member is attached so that the thickness direction is directed to the irradiation direction of the lamp 1. Since the direction of the light emitted from the light emitting unit 3a and the first reflecting plate 4 are parallel to each other, only the light emitting unit 3a is substantially linear when the light source 2 is turned on. As a shining thing.

  Here, when the first reflector 4 is described, the first reflector 4 is subjected to mirror surface treatment 4b on the front and back surfaces, and is cut on three sides excluding one side on the light source box 3 side. Then, one side of the light source box 3 side is bent to form a cut-and-raised small reflection plate 4a (hereinafter, abbreviated as the small reflection plate 4a). In addition, as shown in FIG. 2, the said small reflecting plate 4a is considered so that the position and bending direction when providing in the 1st reflecting plate 4 may not overlap, and 2nd reflecting plates 5U and 5D. It is considered that the light reaches uniformly.

  Further, the angle of bending at one side of the light source box 3 at this time is emitted from the light emitting unit 3a of the light source box 3 whose traveling direction is changed by the small reflector 4a, for example, around 45 °. It is preferable that the light is within a range reaching the range where the second reflecting plates 5U and 5D exist.

  Further, as is clear from FIG. 2, the direction in which the small reflector 4a is bent may be upward or downward. Therefore, when bent upward, the reflected light from the small reflecting plate 4a reaches the upper second reflecting plate 5U, and when bent downward, the reflected light from the small reflecting plate 4a becomes the lower second reflecting plate 5U. Accordingly, the second reflecting plates 5U and 5D are subjected to mirror surface processing 5a on the surfaces facing each other.

  Here, the present invention does not limit the member forming the first reflecting plate 4 to an opaque member such as a metal, and although not shown, the small reflecting plate 4a is formed by, for example, resin injection molding. Then, the shape up to the bending is formed, and then the entire surface or a necessary portion is vacuum-deposited with aluminum, and the entire surface or the necessary portion may be mirror-finished. The small reflector 4a is cut and raised from the first reflector 4. However, the present invention is not limited to this, and the first reflector 4a is formed in a shape including the small reflector 4a by resin injection molding or the like. The reflecting plate 4 may be molded, and a mirror surface treatment may be performed on a necessary part.

  With the above configuration, in the lamp 1 of the present invention, when the succeeding vehicle or the like watches the lighted state, the light from the small reflecting plate 4a is projected onto the surfaces of the second reflecting surfaces 5U and 5D. As shown in FIG. 3, a plurality of positions of the second reflecting plates 5U and 5D become a mapping G that shines in a so-called spot shape. In addition, at this time, each spot has a different position depending on the position of the small reflecting plate 4a provided on the first reflecting plate 4 or the position projected on the second reflecting plates 5U and 5D. , A sense of depth and a three-dimensional feeling can also be obtained.

  FIG. 4 shows another embodiment of the lamp 1 according to the present invention, and is intended to further enhance the above-described depth feeling and stereoscopic effect. As described above, in the lamp 1 of the present invention, the irradiation direction side of the first reflecting plate 4 and the second reflecting plates 5U, 5D is covered with the outer lens 6.

  Therefore, if the lens cut 6a having an appropriate number of prisms or the like is formed at an appropriate position on the front surface or the back surface of the outer lens 6, the first reflector 4 is turned on when the lamp 1 is turned on. The light from the light source 2 passing through the second reflectors 5U and 5D shines, and a further sense of depth is obtained.

  5 shows an example in which the shape of the small reflecting plate 4a is changed. By making the shape of the small reflecting plate 4a an arbitrary shape such as a star as shown in the figure, this is shown. The shape and pattern are reflected on the second reflecting plates 5U and 5D and reflected on the outer lens 6. As shown in FIG. 5, for example, the function as a taillight can be performed brilliantly. Further, by changing the shape of the small reflecting plate 4a, it is possible to display a pattern 6b or the like according to the vehicle type name, grade, or option.

  Therefore, according to the present invention, the lamp 1 having the above-described configuration is used, so that the lamp can be displayed with a novel appearance that does not exist at the time of lighting or extinguishing. Ornaments and the like are unnecessary, and an effect more than that of attaching them can be achieved.
