Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a vehicle lamp that is installed on the fender and emits light toward the driver.

《Prior art》 This type of lighting equipment can be used to check whether or not a car headlamp is on at night, for example.
It is used to check the width of the vehicle. An example of such a conventional lamp is shown in FIGS. 4 and 5. This lamp m includes a light cable b for receiving and guiding light from a light source a of a headlamp (not shown), a housing c to which an end of the light cable b is attached, and a housing c installed in the housing c. lens e and this lens e
The housing c is provided with a cover d formed to open the front face thereof and cover the front face of the housing c. The lens e is integrally formed by fitting, for example, a colorless transparent lens part f and an orange transparent lens part g, and has a total reflection surface k, a light receiving surface l, and an output surface n. This lamp m
is fixed to the vehicle body i with a clip j by inserting a leg o provided on the back surface of the housing c into a mounting hole in the vehicle body i via a gasket h.

<<Problem to be solved by the invention>> However, the lens e of such a conventional lamp m has the flat surface of the lens e directly in contact with the end output surface of the light cable b that has guided the light from the light source a, Since this flat surface is used as the light-receiving surface l, a beam of light in a range corresponding to the diameter of the light cable b enters into the lens part f, is completely reflected on the total reflection surface, which is an inclined surface, and reaches the output surface n. The light enters the lens portion g and exits rearward with a light emitting area s, which is visually recognized by the driver.

In this way, the conventional lamp m has a light emitting area s that is approximately equal to the end emission area of the light cable b.
There are problems such as poor visibility from the driver's seat, and because the light has directionality in the direction of travel, it cannot be seen from a wide range, resulting in a lack of reliability. In particular, the light fixture m installed on the fender on the passenger seat side has extremely poor visibility from the driver's seat, so if this cannot be ignored, use a reflective surface with an appropriate reflection angle facing left and right. A lens provided with k must be used, and there was a problem in that the cost would be high because the left and right lenses could not be used in common.

Therefore, the purpose of this invention is to provide a low-cost vehicular lamp that has a simple structure, has a large light emitting area, can be seen from a wide range, and has good visibility.

<<Means for Solving the Problem>> In order to achieve this object, the vehicle lamp of this invention is provided with a lens provided on the fender for emitting light from a light source toward the driver; It is characterized in that a plurality of cylindrical holes are provided in front of a reflective surface that reflects light from a light receiving surface toward an output surface.

<<Operation>> The light from the light source is first reflected by the reflecting surface, then diffused by the plurality of holes, and emitted from the output surface, where it is visible from a wide range.

<<Example>> Hereinafter, an example of this invention will be described with reference to the drawings.

As shown in FIG. 1, a second light source made of optical fiber is located between a first light source 1, which is a light bulb of an automobile headlamp, and a lamp 10 placed and fixed on the fender panel 7 of the automobile. It is connected by a light cable 2. One end 21 of the light cable 2 receives light from the first light source and guides the light into the lamp 10. The other end portion 22 of the light cable 2 is inserted into an insertion hole 32 of a boss portion 31 provided in the housing 3 and fixed. A lens 5 is mounted on the front upper surface of the housing 3.
is fixed by its lower flange portion 51 being locked to the locking protrusion 33 of the housing 3. A box-shaped cover 4 is provided on the upper rear surface of the housing 3 so as to cover the reflective surface 54 of the lens 5, and its upper end 42 is engaged with the upper end of the reflective surface 54 of the lens 5. Protruding legs 41
is inserted into the hole 34 at the front of the housing 3 and fixed by caulking on the back surface of the housing 3. This lamp 10 has a housing 3 as in the conventional case.
A mounting leg 35 protruding from the back side of the fender panel 7 is inserted through a gasket 6 into a mounting hole of the fender panel 7, and is fixed to the fender panel 7 with a clip 8.

The output end surface of the end portion 22 of the light cable 2 faces into a recess 36 formed on the upper surface of the housing 3, and a portion of the flat bottom surface of the lens 5 faces there as a light receiving surface 53.

The lens 5 is formed of transparent acrylic resin into a substantially trapezoidal shape, and above the light receiving surface 53 is an output surface 5.
A reflective surface 54 is formed which is inclined toward 2. This reflective surface 54 is connected to the output surface 52 as in the conventional case.
It is a flat total reflection surface facing towards the exit surface 5.
As shown in the plan view of FIG. 2 and the bottom view of FIG. 3, 2 is a cylindrical lens surface that is convex toward the outside. And this reflective surface 5
A plurality of cylindrical holes 9 are provided at the front of the cylindrical hole 4 so as to be perforated approximately vertically from the bottom side at regular intervals and alternately.

Since the lens 5 is formed in this way, as shown in FIG. The light enters the lens 5, is totally reflected by the total reflection surface 54, which is an inclined surface, and then enters each hole 9 in front of it.
As shown in FIG. 2, a part of the light enters another hole 9 and is similarly diffused, and then a part of the light enters another hole 9 and is diffused in the same way. The light is diffused by the light emitting surface 52 and emitted. At this time, the area around the hole 9 lights up and is visible from a wide range.

Note that the light-receiving surface 53 may be a single spherical convex or concave lens that is integrally molded on the bottom surface of the lens 5 and faces into the recess 36 on the top surface of the housing 3. Further, the inner wall surface of the cylindrical hole 9 may be honed to further diffuse the incident light.

Further, in the above embodiment, the light cable 2 is used as the second light source, but a light emitting diode or the like connected in series with the first light source 1 may be used as the second light source.

<<Effects of the invention>> As explained above, the vehicle lamp of this invention diffuses the light from the light source through the plurality of cylindrical holes provided between the reflection surface and the output surface. Since the light emitting area becomes larger and can be seen from a wider range, visibility is greatly improved.
