A lens 5 is fitted to the inside surface of the housing 2 to improve light distribution characteristics.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an auxiliary stop lamp, commonly referred to as a high-mount stop lamp, which is installed at a higher position than the original stop lamp, for example, within the rear window.

[Conventional technology]

FIG. 5 shows an example of a conventional auxiliary stop lamp 90 of this type, which has a narrow vertical width and a wide horizontal width in order to not obstruct the driver's field of view and improve visibility from following vehicles. , a long lamp body 91 is fixed to the ceiling 11 of a car, for example, with a stay 92 so that the irradiation direction is directed toward the rear window glass 10, and the stay 92
is provided with a hinge portion 93 so as to be able to adjust the irradiation direction, thereby correcting the difference in inclination of the ceiling 11 depending on the vehicle type. Incidentally, the lamp body 91 of the auxiliary stop lamp 90 is a lens 9 that has a lens cut to satisfy the light distribution characteristics.
1a will be adopted.

[Problem to be solved by the invention]

However, the shape of the rear window glass 10 varies depending on the purpose of use of the vehicle, such as a passenger car or a cargo vehicle, or depending on the design, such as a sedan or a coupe. Stay 9
2, or in extreme cases, even the shape of the lamp body 91 must be changed. This makes the production line complicated and reduces sales. This has also become complicated, and solving this problem has become a problem.

[Means to solve the problem]

The present invention is a specific means for solving the conventional problems described above, and includes a housing formed of a transparent and flexible member in a substantially cylindrical shape, and a light emitting element mounted on a flexible substrate. and an inner lens formed of a transparent and flexible member, the light source is rotatably mounted within the housing approximately coaxially with the housing, and the inner lens is mounted within the housing so as to be rotatable approximately coaxially with the housing. By providing an auxiliary stop lamp characterized in that the light source is installed with a rotation correction means so as not to cause positional deviation due to rotation of the light source, an auxiliary stop lamp that can be installed on all types of vehicles is provided. As possible,
This solves the conventional problems mentioned above.

【Example】

Next, the present invention will be explained in detail based on embodiments shown in the drawings. The reference numeral 1 in FIG. 1 is an auxiliary stop lamp according to the present invention, and this auxiliary stop lamp 1 is different from the conventional example in that it is attached to the interior side of the rear window glass 10 of an automobile. Similarly, the housing 2 is formed of a transparent and flexible resin member or the like into a substantially cylindrical shape, and its cross-sectional shape is shaped like a water drop, for example, as shown in FIG. The flat surface 2a is directly attached to the rear window glass 10 by adhesive or other appropriate means. Further, the light source 3 is made up of a similarly flexible substrate 3a and a plurality of light emitting elements 3b, such as LEDs, mounted in a row on the substrate 3a, and has openings 2b at both ends of the housing 2. The housing 2 is rotatably mounted substantially coaxially with respect to the housing 2 by being pivotally supported by a cap 4 attached to the housing 2 . Here, to explain the housing 2 in more detail, with the above configuration, the housing 2 can have the same shape in all cross sections perpendicular to the cylindrical axis,
For example, it can be formed by means such as extrusion molding, and productivity can be improved by forming a long piece in advance and cutting it to the required length before use. On the other hand, when the housing 2 is formed by extrusion molding, the lens can be cut in the direction along the cylindrical axis, but it is impossible to cut the lens in the direction perpendicular to the axis, especially in the left and right directions. This may cause dissatisfaction with the light distribution characteristics of this type of auxiliary stop lamp 1, which is required to have a wide irradiation angle. In order to cope with the above situation, the present invention provides an inner lens 5.
In this embodiment, the inner lens 5 is formed into a flat plate shape with a lens cover 5a made of a transparent and flexible member similar to the housing 2, The inner lens 5 can be attached by utilizing its elasticity by being curved and engaged with a rib 2C provided on the inner diameter of the housing 2. At this time, as explained above, the light source 3 is rotatable with respect to the housing 2 and the mutual positions of both 2 and 3 change, so the inner lens 5 serves as a rotation correction means. The provided range covers at least the range of rotation of the light source 3. Next, the function and effect of the auxiliary stop lamp 1 having the above structure will be explained. According to the present invention, the housing 2, the light source 3, and the inner lens 5 are formed of flexible members. Since this auxiliary stop lamp 1 can be freely curved to follow the curvature of the rear window glass 10, it can be directly attached to any shape of the rear window glass 10, and furthermore, it can be attached directly to the rear window glass 10 of any shape. The difference in the angle of inclination will be corrected by the rotation of the light source 3, but at this time, the inner lens 5 will cover all the rotation angles of the light source 3, so that the light distribution characteristics will be corrected. No fluctuation occurs. What is shown in FIG. 3 is another embodiment of the present invention, which is different from the previous embodiment in which the inner lens 5 is fixed to the housing 2 side as a rotation correction means, and the inner lens 5 is arranged to cope with the rotation of the light source 3. In contrast, the rotation correction means of this embodiment has a claw portion θa formed on the inner lens 6 and is fixed to the substrate 3a of the light source 3, as shown in FIG. By doing this, the inner lens 6 also rotates as the light source 3 rotates, and the light distribution characteristics are maintained regardless of the degree of rotation. Note that the effects other than those described above are the same as those of the previous embodiment, so a detailed explanation will be omitted here.

【Effect of the invention】

As explained above, according to the present invention, both the transparent housing and the light source are formed of flexible members, and the light source is rotatable with respect to the housing, so that the housing can be attached, for example, by pasting. By adhering and attaching it to the rear window glass, it is possible to provide an auxiliary stop lamp whose irradiation direction can be adjusted correctly regardless of any inclination or curvature of the rear window glass,
In addition, by providing the inner lens that forms the light distribution characteristics with a rotation correction means that corresponds to the rotation of the light source with respect to the housing, even when the irradiation direction is adjusted by the rotation described above, the specified By making it possible to obtain light distribution characteristics and thereby making it possible to standardize this type of auxiliary stop lamp, it is extremely effective in promoting rationalization in terms of production and sales.
