Abstract

PROBLEM TO BE SOLVED: To further enhance the viewability of a signal light. SOLUTION: The signal light 1 irradiates a globe 15 with light from the light source 11 through a light-passing member 12. An initial reflective surface 16 of the light-passing member 12 internally reflects part of the entered light toward the globe 15, passing the remaining light to a reflective member 13. A second reflective surface 17 of the reflective member 13 makes total internal reflection of the light passed through the initial reflective surface 16 toward the globe 15. The initial and the second reflective surfaces 16 and 17 are disposed overlapped as viewed from the axial direction, being mutually spaced apart in the axial direction. This makes it possible to secure a wide area for each reflective surface 16 and 17, and to irradiate light at plural positions separated in the axial direction. It is further made possible to secure a wide viewing angle and to make the size small.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed in an automatic machine, a production line, a parking lot, a dangerous place, and the like, and is used to signal various states such as a shortage of materials, a jammed work, a full load, and a danger. It relates to a signal indicator light.

[0002]

2. Description of the Related Art The above-mentioned signal indicator lamps include, for example, those having a cylindrical shape. 8 has a substantially cylindrical globe 91 capable of emitting light from the entire circumferential surface thereof, a light source 92 such as an LED disposed in the globe 91, and a light source 92. A plurality of total reflection surfaces 93 and 94 are provided for totally reflecting light from the globe toward the globe 91.

In the signal indicator light 90, light is dispersed and reflected at a plurality of positions (ranges 95 and 96 of the globe 91 corresponding to the respective positions) corresponding to the respective total reflection surfaces 93 and 94. By illuminating, the visibility can be improved as compared with the one having a single total reflection surface. For this purpose, the plurality of total reflection surfaces 93 and 94 are arranged in a stepwise manner apart from each other in the axial direction of the cylindrical shape of the globe 91. Further, in response to the light from the light source 92 being irradiated in the axial direction, the plurality of total reflection surfaces 93 and 94 are arranged so as to be shifted in the radial direction so as not to overlap each other.

[0004]

However, since the plurality of total reflection surfaces 93 and 94 are shifted from each other in the radial direction, if the size of each of the total reflection surfaces 93 and 94 is widened, the signal indicator lamp is turned on. It tends to be larger. On the other hand, if each of the total reflection surfaces 93 and 94 is made smaller to prevent an increase in the size, the range in which the reflected light from each of the total reflection surfaces 93 and 94 reaches correspondingly becomes narrower. In other words, the so-called viewing angle, which is the range in which the light having the high intensity can be visually recognized and the range around the signal indicator lamp, is narrowed.

It is an object of the present invention to solve the above-mentioned technical problems and to provide a signal indicator light which can be downsized while ensuring high visibility with a wide viewing angle.

[0006]

According to the first aspect of the present invention, there is provided a signal display lamp in which light emitted from a light source to a light transmitting member passes through a globe and emits light. A first reflecting surface provided to split light from the light source into transmitted light and reflected light toward the globe; and a second reflecting surface totally reflecting transmitted light from the first reflecting surface toward the glove. And a signal indicator lamp provided with the following.

According to the present invention, light can be dispersed and emitted from a plurality of positions corresponding to each reflecting surface by using a plurality of reflecting surfaces.
High visibility of the signal indicator can be ensured. In addition, since light can be transmitted through the first reflecting surface, the first reflecting surface and the second reflecting surface can be arranged so as to overlap when viewed from the light source while securing the size of each reflecting surface. Compared with the conventional configuration in which the total reflection surface is arranged, it is possible to reduce the size of the signal indicator while securing a wide viewing angle corresponding to the size of each reflection surface.

According to a second aspect of the present invention, in the signal indicator lamp according to the first aspect, the translucent member includes an incident surface through which light from the light source is incident, and the incident surface is provided on the incident surface. Forming a lens for converging or diffusing light;
Is characterized in that when transmitted through the incident surface, a part of the light converged or diffused by the lens is internally reflected toward the glove, and the remaining light is transmitted toward the second reflective surface. To provide a signal indicator light.

According to the present invention, the light can be enhanced by, for example, a lens that converges the light, so that the visibility can be further improved. Further, since the light spread angle can be widened by the lens that diffuses the light, the light can be emitted more widely. In addition, since the light-transmitting member can be used also as the lens supporting member, it is not necessary to provide a lens supporting member separately from the light-transmitting member, so that the structure can be simplified.

According to a third aspect of the present invention, there is provided the signal indicator lamp according to the first or second aspect, further comprising a support for supporting the light-transmitting member, and a tapered inclined surface extending to the support. A signal indicating lamp provided with two reflecting surfaces is provided. According to the present invention, it is possible to easily and simply assemble the two reflecting surfaces in alignment with each other simply by assembling the light transmitting member to the support. According to a fourth aspect of the present invention, in the signal indicator lamp according to the third aspect, the light transmitting member is attached to the support by fitting the fitting portions of the support and the light transmitting member to each other. The present invention provides a signal indicator light characterized by the following.

According to the present invention, the light transmitting member can be easily attached to the support by fitting the fitting portions together. Since the fitting portions can directly engage with each other, the two reflecting surfaces can be accurately positioned. In addition, since each fitting portion can be formed integrally with the corresponding support and the light transmitting member, the structure can be simplified.

The light transmitting member 12 is an annular member and has a fitting hole 40 (see FIG. 3) extending in the axial direction at the center.
The translucent member 12 has a substantially right-angled triangular cross-section taken in the circumferential direction. The light transmitting member 12 is made of a light transmitting synthetic resin such as methacrylic resin, for example, and is colorless and transparent. The light transmitting member 12 includes an incident surface 41 for receiving light from the light source 11 therein, the above-described first reflecting surface 16 for internally reflecting a part of light entering from the incident surface 41, And an emission surface 42 for emitting the light reflected by the reflection surface 16. An optical path for guiding light is formed inside the light transmitting member 12.

The incident surface 41 is located on the upper end surface in the axial direction, and is formed by a flat surface facing the light source 11. The emission surface 42 is arranged to face the inner peripheral surface 31 of the globe 15 and has a circular surface. The first reflection surface 16 is formed on a tapered inclined surface 43 formed of a conical surface. Translucent member 1
In 2, the light from the light source 11 (see L1 in FIG. 2) passes through the entrance surface 41, travels inside, and reaches the first reflection surface 16. Part of the light from the light source 11 is bent at a substantially right angle on the first reflection surface 16 and internally reflected toward the globe 15 to become reflected light (see L2 in FIG. 2). Further, the remaining light travels substantially straight on the first reflection surface 16 and is transmitted, and becomes transmitted light (see L3 in FIG. 2).

Here, the ratio of the light transmitted and reflected by the first reflection surface 16 depends on the material of the light transmitting member 12 and the first
Is appropriately determined according to the angle between the reflecting surface 16 of the above and the light rays entering the same. The column 14 is a cylindrical columnar member that extends through the fitting hole 40 of the translucent member 12 and extends in the axial direction. The second reflecting surface 17 is provided on a tapered inclined surface 45 such as a conical surface of the reflecting member 13 extending from the lower end of the support 14.
The support 14 and the reflection member 13 are integrally formed,
A connecting member 19 for connecting the display unit 2, the cover 3, and the case 4 adjacent above and below is configured.
The upper end of the support 14 of the connecting member 19 is connected to a substrate 18 on which the light source 11 is mounted. The connection member 19 of the upper display unit 2 is connected via the substrate 18.
At the lower end of the reflecting member 13 of the connecting member 19, a fitting recess 46 is formed in which the outer peripheral edge 37 of the substrate 18 of the display unit 2 adjacent below fits. Thus, the pillar 1

The reflecting member 13 is formed in a truncated cone shape.
The tapered inclined surface 45 of the outer peripheral surface is formed so as to face the tapered inclined surface 43 of the light transmitting member 12. The tapered inclined surface 45 and the outer peripheral surface 47 of the column 14 are, for example, aluminum vapor-deposited so as to be a total reflection surface that totally reflects light, and the second reflection surface 17 is provided on a part thereof. . The second reflecting surface 17 is disposed so as to overlap with the first reflecting surface 16 when viewed from the light source 11, and is substantially the same as the first reflecting surface 16, more specifically, the first reflecting surface 16. It is formed slightly larger than the surface 16. The tapered inclined surface 45 forms a predetermined angle with the axial direction so that the second reflecting surface 17 bends the light traveling in the axial direction outward in the radial direction at a substantially right angle and totally reflects the light. It is formed.

Also, the first and second reflecting surfaces 16, 17
Are arranged such that most of them do not overlap each other when viewed from the radial direction which is the side. Thereby, the reflected light from the second reflection surface 17 can be directly incident on the globe 15 without being substantially blocked by the first reflection surface 16. In addition, the first and second
The reflective surfaces 16 and 17 overlap with most of the vertical direction of the globe 15 when viewed from the side in the radial direction. Thus, the two reflecting surfaces 16 and 17 cooperate with each other so that light can be reflected toward substantially the entire globe 15.

The support structure 14 and the light transmitting member 12 are provided with a connection structure 20 for connecting to each other. Please refer to FIG. 2 and FIG. The connection structure 20 has fitting portions 48 and 44 formed on the column 14 and the light transmitting member 12 and fitted to each other. These fitting portions 44,
The light transmitting members 12 are attached to the columns 14 by fitting the 48 into each other. Fitting portion 48 of support 14
Consists of a fitting circumferential surface formed on the outer circumferential surface near the upper end of the column 14. In the vicinity of the upper end of the column 14, the engaging claw 4 is provided.
9 are formed. FIG. 2 is a cross-sectional view in which both the fitting portion 48 and the engaging claw 49 are illustrated. The fitting circumferential surface and the engaging claw 49 are formed side by side in the circumferential direction. The support 14 is formed with a groove extending in the vertical direction at a predetermined depth from the upper end thereof, and this groove separates the fitting circumferential surface from the engaging claw 49. Thereby, the engagement claws 49
Has flexibility due to its elasticity. Engaging claw 49
Are formed in a hook shape protruding radially outward. Further, the support 14 is formed with an annular seat 50 that receives and supports the light transmitting member 12.

The fitting portion 44 of the light transmitting member 12 is a peripheral portion of the fitting hole 40 formed at the center. In the connection structure 20, when the upper part of the support 14 is fitted into the fitting hole 40 of the light transmitting member 12 and the lower surface of the periphery of the fitting hole 40 is brought into contact with the seat 50 of the support 14, the periphery of the fitting hole 40 is The part and the fitting circumferential surface of the column 14 fit directly. Thereby, the light transmitting member 12
Are positioned without play in the radial direction. At the same time, the periphery of the fitting hole 40 is sandwiched and engaged between the seat portion 50 and the engaging claw 49, whereby the light transmitting member 12 is positioned without play in the axial direction.

The connection structure 20 is not limited to the above structure. For example, as shown in the perspective view of FIG. 4, the light transmitting member 12 has an annular shape through which the support 14 is inserted, and is formed by fitting a plurality of divided bodies 21 and 22 divided along the radial direction to each other. You may make it. Division 2
Pins 23 and holes 24 that fit each other may be provided for fitting between the first and the second 22. In addition, a known structure can be used for the connection structure 20. In the display unit 2, the light from the light source 11 is emitted downward in the axial direction. The light from the light source 11 is irradiated with a sufficient intensity to obtain visibility from the surroundings and in a wide angle range. The entire range in the radial direction of the first reflection surface 16 is included in the irradiation range of the light having the above-described intensity.
The light is split at the first reflection surface 16 into transmitted light and reflected light.

The transmitted light after branching of the first reflecting surface 16 (FIG. 2)
L3) is totally reflected by the second reflecting surface 17 (FIG. 2).
L4), light is mainly emitted from the lower part of the globe 15. Further, the reflected light after branching on the first reflection surface 16 (see L2 in FIG. 2) travels inside the translucent member 12 and passes through the light exit surface 4.
2 and is mainly emitted from the upper part of the globe 15. As described above, the light from the light source 11 is uniformly and widely emitted from almost the entire globe 15, and the light from the light source 11 is reliably emitted to the outside.

Also, the first and second reflecting surfaces 16, 17
Are arranged apart from each other in the axial direction.
The reflected light from the light sources 6 and 17, particularly the strong light among the light from the light source 11, is dispersed and emitted through the globe 15 at a plurality of positions separated from each other in the axial direction. Therefore, the visibility of the signal indicator lamp 1 can be enhanced by the plurality of strong lights. Further, in the display unit 2, since the plurality of light sources 11 are arranged in the circumferential direction, the globe 15 emits strip-shaped light extending in the circumferential direction.

Further, the light from the light source 11 is applied to both the reflection surfaces 1.
Light that is not directed to 6 and 17 is transmitted through the globe 15 directly or reflected by the reflecting surface of the support 14 and emitted from the globe 15. Further, the embodiment of the present invention shown in FIG. 5A and the conventional configuration having a plurality of total reflection surfaces 93 and 94 shifted in the axial direction shown in FIG. Compare as the same. In the present invention, the light from the single light source 11 in the range of the spread angle D1 is reflected or transmitted by the first reflection surface 16 while maintaining the spread angle of the light (the spread angle range D2 of the reflected light). (The spread angle range of transmitted light D3 = D1), and the transmitted light is reflected by the second reflection surface 17 as it is. As a result, the above-mentioned light from the light source 11 becomes two large spots on the outer peripheral surface 32 of the globe 15 as shown by hatching in FIG. On the other hand, in the conventional configuration, in the light from the single light source 11 in the range of the spread angle D1, part of the light is reflected by the total reflection surface 93 (angle range D5), and the remaining light is Is reflected by the total reflection surface 94 (angle range D6). As a result, the light from the light source is formed on the outer peripheral surface 32 of the globe 15 into two small spots as compared with the case of the present invention.

As shown in the sectional view of FIG. 6, the signal indicator lamp of the second embodiment has a convex lens 25 formed on the incident surface 41 of the light transmitting member 12 of the first embodiment. In the second embodiment,
The third embodiment differs from the first embodiment in the following points, and the other points are configured in the same manner, and the same reference numerals are given and the description is omitted. The same applies to other embodiments described below. The translucent member 12 includes an incident surface 41.
Has a convex curved surface 51 formed on the surface thereof. The convex curved surface 51 is disposed at a position facing the light source 11, and a plurality of convex curved surfaces 51 are provided corresponding to the plurality of light sources 11. The area of the light transmitting member 12 corresponding to each convex curved surface 51 is the convex lens 2 described above.
5. The light from the light source 11 is
The light is refracted by the convex curved surface 51 and enters the inside so as to converge inside. When transmitting through the entrance surface 41, the convex lens 25
A part of the light converged by is reflected internally by the first reflecting surface 16 toward the globe 15, and the remaining light passes through the first reflecting surface 16 and travels to the second reflecting surface 17.

The signal indicator of the third embodiment has a concave lens 26 formed on the incident surface 41 of the light transmitting member 12 of the first embodiment, as shown in the sectional view of FIG. The light transmitting member 12 is
It has a concave curved surface 52 formed on the incident surface 41. The concave curved surface 52 is arranged at a position facing the light source 11, and a plurality of concave curved surfaces 52 are provided corresponding to the plurality of light sources 11. The area of the light transmitting member 12 corresponding to each concave curved surface 52 constitutes the concave lens 26 described above. Light from the light source 11 is diffused inside the light transmitting member 12 so that the concave
Is refracted by and incident inside. Part of the light diffused by the concave lens 26 when transmitting through the incident surface 41 is internally reflected by the first reflecting surface 16 toward the globe 15, and the remaining light is transmitted through the first reflecting surface 16. It goes to the second reflection surface 17.

As described above, according to each embodiment of the present invention,
By using the plurality of reflecting surfaces 16 and 17 spaced apart from each other, light can be dispersed and emitted from a plurality of positions on the globe 15 corresponding to the respective reflecting surfaces 16 and 17, and high visibility of the signal indicator lamp 1 can be secured. In addition, since light can be transmitted through the first reflecting surface 16, the first reflecting surface 16 and the second reflecting surface 17 are arranged so as to overlap each other when viewed from the light source 11 while ensuring a large size of each of the reflecting surfaces 16 and 17. it can. As a result, as compared with the conventional configuration in which a plurality of total reflection surfaces are shifted in the radial direction, each reflection surface 16,
The signal indicator lamp 1 can be reduced in size while ensuring a wide so-called viewing angle determined according to the size of 17.

In other words, when the size of the signal indicator lamp 1 is made substantially the same, each of the reflection surfaces 16 and 17 can be enlarged, so that the so-called viewing angle can be widened accordingly, thereby improving the visibility. be able to. Note that, in general, the size of the reflection surface and the viewing angle are in a substantially proportional relationship. This is because the light from the light source 11 is irradiated with a sufficient intensity to obtain visibility and an angle range sufficiently wider than the angle range corresponding to the reflection surface.

Further, the second reflection surface 17 is a total reflection surface, and in particular, can totally reflect transmitted light from the first reflection surface 16, so that light can be prevented from being transmitted needlessly. Therefore, the light can be reliably and effectively used at the maximum efficiency as compared with the case where a reflection surface that transmits and reflects the same light as the first reflection surface 16 is provided instead of the second reflection surface 17.
Further, since the second reflecting surface 17 totally reflects light toward the globe 15, it is preferable for effective use of light.

In the second embodiment, since the light can be enhanced by the convex lens 25 that converges the light, the visibility can be further improved. Further, in the third embodiment, the concave lens 26 for diffusing the light can widen the range of the spread angle of the light, so that the light can be more evenly emitted. Moreover, in the second and third embodiments, the light-transmitting member 12 can be used also as the support member for the lenses 25 and 26, so that there is no need to provide a lens support member separately from the light-transmitting member 12, and as a result, the signal display lamp is provided. 1 can be simplified.

Further, in each embodiment, simply assembling the translucent member 12 to the column 14 can easily and easily assemble the two reflection surfaces 16 and 17 in a state where they are aligned with each other. The connection structure 20 is formed by fitting the fitting portions 48 and 44 of the support 14 and the light transmitting member 12 together.
The translucent member 12 can be easily attached to the column 14.

Further, since the fitting portions 48 and 44 can be directly engaged with each other, it is possible to accurately position the reflecting surfaces 16 and 17 with each other. Further, since the fitting portions 48 and 44 can be fitted to each other without play, positioning can be performed with high accuracy. In addition, since the fitting portions 48 and 44 can be formed integrally with the corresponding columns 14 and the light transmitting members 12, the structure can be simplified. Note that one light source 11 may be arranged on the axis, or may be arranged on a plurality of concentric circles.

Further, a plurality of at least one of the first reflecting surface 16 and the second reflecting surface 17 may be provided. Also,
The distance between the first reflection surface 16 and the second reflection surface 17 is not particularly limited. For example, most of the two reflecting surfaces 16 and 17 may be arranged so as to overlap each other when viewed from the radial direction. Further, the two reflecting surfaces 16 and 17 may be arranged so as not to overlap each other when viewed from the radial direction. In addition, various design changes can be made without changing the gist of the present invention.
