Description

Detailed Description of the Invention [Industrial applications]

The present invention generally refers to a high mount stop lamp, and relates to an auxiliary stop lamp provided at a position higher than an original stop lamp, for example, in a rear window.

[Prior art]

An example of a conventional auxiliary stop lamp 90 of this type is shown in FIG. 5, which has a narrow vertical width and a wide horizontal width in order to improve visibility from a following vehicle without hindering the driver's view. The long lamp 91 is fixed to the ceiling 11 of an automobile, for example, with the stay 92 so that the irradiation direction is directed toward the rear window glass 10. The stay 92 has a hinge portion.
93 is provided so that the irradiation direction can be adjusted, and the difference in the inclination of the ceiling 11 depending on the vehicle type is corrected. It should be noted that the lamp body 91 of the auxiliary stop lamp 90 employs a lens 91a that is lens-cut to satisfy the light distribution characteristics.

[Problems to be Solved by the Invention]

However, the rear window glass 10 has various shapes depending on the purpose of use of a car such as a passenger car and a freight car, or a design such as a sedan or a coupe. Stay 92
It is necessary to prepare a large variety of products, such as preparing a large number of products, or even changing the shape of the lamp body 91 in an extreme case, which complicates the production line and increases the sales aspect. It has become complicated, and the solution to this point has been an issue.

[Means for Solving the Problems]

As a concrete means for solving the above-mentioned conventional problems, the present invention includes a housing formed of a transparent and flexible member in a substantially cylindrical shape, and a plurality of light emitting elements on a flexible substrate. It is composed of a mounted light source and an inner lens formed of a transparent and flexible member, the housing has substantially the same shape in a cross section orthogonal to a cylindrical axis, and the light source is in the housing. The inner lens is rotatably mounted substantially coaxially with the housing, and the inner lens covers the rotation range of the light source in the housing and has a lens cut in a direction orthogonal to the axis of the housing. By providing an auxiliary stop lamp characterized by, it is possible to provide an auxiliary stop lamp that can be attached to all vehicle models, and to solve the above-mentioned conventional problems. .

【Example】

Next, the present invention will be described in detail based on the embodiments shown in the drawings. Reference numeral 1 in FIG. 1 denotes an auxiliary stop lamp according to the present invention. The auxiliary stop lamp 1 is mounted on the inside of a rear window glass 10 of an automobile, which is different from the conventional example. Similarly, the housing 2 is formed of a transparent and flexible resin member into a substantially cylindrical shape, and the cross-section of the housing 2 is formed in a water drop shape as shown in FIG. 2, for example. The flat surface 2a is directly attached to the rear window glass 10 by an appropriate means such as adhesion. Further, the light source 3 includes a flexible substrate 3a and a flexible substrate 3a.
A plurality of light emitting elements 3b mounted on the 3a in a row, for example, LEDs, and the openings 2b at both ends of the housing 2
It is rotatably attached to the housing 2 substantially coaxially, for example, by being supported by the cap 4 attached to the housing 4. Here, the housing 2 will be described in more detail. With the above-described configuration, the housing 2 can have the same shape in all cross sections orthogonal to the cylindrical axis.
For example, it can be formed by means of extrusion molding or the like, and it is possible to improve productivity by forming a long one in advance and cutting it to a required length for use. On the other hand, when forming by the above-mentioned extrusion molding, the housing 2 can freely perform lens cutting in the direction along the cylindrical axis, but lens cutting in the direction orthogonal to the axis becomes impossible, and particularly in the left-right direction. There is a possibility of dissatisfaction with the light distribution characteristics of this type of auxiliary stop lamp 1 which requires a wide irradiation angle. In the present invention, in order to cope with the above situation, the inner lens 5
In this embodiment, the inner lens 5 is formed in a flat plate shape with a lens cut 5a using a transparent and flexible member similar to the housing 2. The inner lens 5 is attached by using the elasticity of the inner lens 5 by bending and engaging the rib 2c provided on the inner diameter of the housing 2. At this time, as described above, the light source 3 is made rotatable with respect to the housing 2 and the mutual positions of the two are changed, so that 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 configured as described above will be described. According to the present invention, the housing 2, the light source 3, and the inner lens 5 are made of flexible members. Since the auxiliary stop lamp 1 can be freely curved along the curvature of the rear window glass 10, it can be directly attached to the rear window glass 10 of any shape, and further the rear window glass 10 can be mounted. The difference in the inclination angle is corrected by the rotation of the light source 3, but at this time, the inner lens 5 covers the entire rotation range of the light source 3 to change the light distribution characteristic. Will never occur.

【The invention's effect】

As described above, according to the present invention, the transparent housing and the light source are both formed of a flexible member, and the light source is rotatable with respect to the housing. By adhering to the rear window glass and attaching it, it is possible to provide an auxiliary stop lamp that can correctly adjust the irradiation direction regardless of any inclination and curvature of this rear window glass,
In addition, since the inner lens forming the light distribution characteristic is provided with the rotation assisting means corresponding to the rotation of the light source with respect to the housing, even when the irradiation direction is adjusted by the rotation described above, This makes it possible to obtain a light distribution characteristic, and thus makes it possible to standardize this kind of auxiliary stop lamp, which is extremely effective in promoting rationalization in terms of production and sales.
