Abstract

PURPOSE:To form a reflex reflector regardless of the form of a front lens by forming the reflex reflector of a mirror surface so that it has an optical axis parallel to the advancing direction of a vehicle, and making the position corresponding to the reflex reflector of the front lens transparent. CONSTITUTION:A reflex reflector 4 is formed of a mirror surface so that it has an optical axis parallel to the advancing direction of a vehicle in which a vehicle signal light is mounted on a housing 1, and the position corresponding to the reflex reflector 4 of a front lens 3 is transparently formed. The reflecting surface 4b of the reflex reflector 4 is regularly held vertically to the optical axis (z) so that it is not influenced by the design of the front lens 3. Hence, correction of the design of the reflex reflector 4 for every kind of vehicle signal lighting fixtures is not required, and complication in designing can be eliminated.

Description

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

The present invention relates to a signal lamp such as a tail lamp mounted on a vehicle such as an automobile.

[Conventional technology]

FIG. 4 shows an example of a conventional vehicle signal lamp 90 of this type, in which a front lens 92 is attached to cover the front surface of a housing 91 in which a light source, a reflector, etc. are incorporated. In some cases, the front lens 92 is provided with a reflex reflector 93 that complies with the relevant regulations.
2 is integrally provided by utilizing the total reflection angle of the transparent resin member forming the transparent resin member 2.

[Problem to be solved by the invention]

However, in most cases, the shape of the front lens 92 is determined by giving priority to the design aspect, and is made to follow the shape of the vehicle body 10 as shown in FIG. The reflex reflector 93 that is integrally formed cannot necessarily be formed in an ideal direction, that is, as a surface perpendicular to and perpendicular to the traveling direction of the vehicle, and for this reason, the reflex reflector 93 is This creates a problem that makes design and mold production extremely difficult, and the solution to this problem has been a challenge.

[Means to solve the problem]

As a specific means for solving the above-mentioned conventional problems, the present invention provides a vehicle signal lamp that includes a housing and a front lens tracker and is provided with a reflex reflector, in which the reflex reflector is attached to the housing. A signal light for a vehicle is characterized in that the light axis is parallel to the traveling direction of the vehicle to which the signal light is attached, and is formed of a mirror surface, and a position of the front lens corresponding to the reflex reflector is formed as transparent. By providing this, the reflex reflector can be formed without being influenced by the shape of the front lens, thereby solving the conventional problems described above.

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the reference numeral 1 in FIG. 1 is a vehicle signal light fixture, and it is a conventional example that this vehicle signal light fixture 1 (hereinafter abbreviated as the light fixture 1) has a housing 2 and a front lens 3. However, the reflex reflector 4 is not provided integrally with the front lens 3, but in the present invention, the beam flex reflector 4 is provided integrally with the housing 2, as shown in the main part in FIG. It becomes. To explain the present invention in more detail below, the reflex reflector 4 provided integrally with the housing 2 is designed in consideration of the state in which the lamp 1 is installed in a vehicle (not shown). In this attached state, the flex reflector 4 is formed with its reflective surface 4a being perpendicular and perpendicular to the traveling direction of the vehicle.
a is perpendicular to the optical axis Z of the flex reflector 4. Further, since the housing 2 is normally formed of an opaque resin member, the reflex reflector 4 formed integrally with it is also naturally formed of an opaque resin, and is enlarged in FIG. As shown in FIG. 2, a reflective film 4b is formed on the reflective flex reflector 4, which has been formed by injection molding or the like, by vapor-depositing a material with excellent reflection efficiency such as aluminum, and this makes it a mirror surface with desired characteristics. It is assumed that it can be obtained. The housing 2 is provided with a socket for attaching a light bulb, a reflector for reflecting light from the light bulb toward the front lens 3, etc., but these are well known and do not directly relate to the present invention. Since it is not a part, detailed explanation will be omitted here. Further, the front lens 3 is formed of, for example, a red transparent resin according to a normal method, but since the reflex reflector 4 is provided in the housing 2 according to the present invention, the function of the reflex reflector 4 is improved. In order not to obstruct
A is transparent without any lens cut or the like. Although not shown, depending on the configuration of the lamp 1, an inner lens may be provided on the back surface of the front lens 3. In this case, the lens is cut as described in the section regarding the front lens 3. A similar transmitting portion that does not perform this may be provided in the inner lens as well. By configuring the lamp 1 in this way, for example, the irradiated light from a following vehicle first passes through the transmitting portion 3a of the front lens 3, and then reaches the flex reflector 4, which is provided integrally with the housing 2, and then reaches the flex reflector 4. After being reflected, the light passes through the transparent portion 3a again and reaches the following vehicle, thereby announcing the presence of the own troops. Next, the effects of the lamp 1 of the present invention having the above structure will be explained. According to the present invention, a reflex reflector 4 is attached to the housing 2.
By providing this, the reflective surface 4a of the reflex reflector 4 and the optical axis Z are influenced by the shape of the front lens 3, which was conventionally provided integrally with the front lens 3 and was made to follow the shape of the vehicle body, for example. This makes it difficult to make the reflex reflector 4 vertical for each model of the lamp 1.
This eliminates the need to make design changes depending on the angle. This also applies when manufacturing the mold for the reflex reflector 4, making it possible to use a common mold for all models of the lamp 1. Furthermore, by integrating the reflex reflector 4 with the housing 2, the reflex reflector 4 uses reflection on a mirror surface, and light leakage is higher than that of a conventional glue flex reflector that utilizes the total reflection angle of a transparent member. This improves the reflection efficiency.

【Effect of the invention】

As explained above, according to the present invention, the reflex reflector has an optical axis parallel to the traveling direction of the vehicle on which the vehicle signal light is attached to the housing, and is formed with a mirror surface, and the position corresponding to the reflex reflector of the front lens is By making the vehicle signal lamp transparent, firstly, the reflective surface of the reflex reflector and the optical axis are always kept perpendicular, so as not to be affected by the design of the front lens. This has the excellent effect of eliminating the need to make corrections to the design of the reflex reflector for each model of vehicle signal light equipment and eliminating the complexity of the design.Secondly, for the same reason, the mold of the reflex reflector It enables commonization, and it also makes it possible to fit this pre-formed part into the housing mold, making the mold inexpensive and, in turn, excellent at reducing the cost of the product. It will be effective. Further, by keeping the reflective surface and the optical axis of the reflex reflector perpendicular to each other, and in addition, providing specular reflection, the reflection efficiency is improved and the performance is also excellently improved.
