Utility Model Registration No. 3199430 Gazette

The above-mentioned light emitting lamp with a fall detection function is attached in a direction in which the light emitting surface faces the traveling vehicle (direction visible to the visual eye) in order to improve visibility from a visual operator such as a driver of the traveling vehicle. There is a problem that it becomes difficult to see the light emitting surface due to the sunlight on the light emitting surface in the daytime in fine weather. Further, in the case of nighttime, there is a problem that the driver of the vehicle traveling beside the light emitting light may be induced to look aside.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an electronic device capable of varying the visibility while ensuring the visibility of the light emitting portion of the electronic device installed outdoors. And.

The electronic device of the present invention is an electronic device including a housing having a window portion for radiating light emitted from the light emitting portion on the front surface and accommodating a circuit board assembly related to light emission of the light emitting portion.
The front surface of the housing is characterized by including an overhang portion that protrudes forward from one side and above of the window portion, and a recess that is adjacent to the overhang portion and in which the window portion is located. do.

According to the electronic device of the present invention, the presence of the overhang portion makes it difficult to be exposed to direct sunlight, the visibility of the light emitting portion is improved, and the presence of the recessed portion where the window portion adjacent to the overhang portion is located. The effect of making it difficult to see is obtained depending on the position facing the light emitting portion.

Hereinafter, the construction light assembly of the embodiment according to the present invention will be described with reference to the drawings. In the examples, components having substantially the same function and configuration are designated by the same reference numerals, so that duplicate description will be omitted.

As shown in FIG. 1, at a construction site or the like on a road RD, it is usual to install a plurality of cones 10 for the purpose of marking such as lane regulation. The light emitting surface of the construction light 20 is attached to each cone 10 in a direction facing the traveling vehicle (direction visible to the driver) in order to improve visibility from the traveling vehicle.

On the other hand, in addition to the construction light 20, an electronic device 40 having a light emitting portion may be attached to the cone 10. As shown in FIG. 2, the electronic device 40 is an electronic device 40 having a light emitting unit 22 on a side that does not face the traveling vehicle so that the driver of the traveling vehicle is difficult to see from the viewpoint of safety and prevention of inattentive driving. It is installed facing the front.

Further, it is necessary to ensure the daytime visibility of the light emitting unit (indicator) of the electronic device 40 by the construction worker, but there is a possibility that the visibility may be lowered due to sunlight. Further, the fact that the light of the light emitting portion of the electronic device 40 is visible from the oncoming lane may induce inattentive driving for the safety of the driver of the oncoming vehicle OCC.

By creating a shadow around the light emitting unit 22, the present inventors are less likely to be affected by direct sunlight and improve visibility, and the driver of the oncoming vehicle OCC is difficult to see and is not noticed. We devised an overhang structure for electronic devices that prevent operation.

FIG. 3 shows an embodiment of the present invention. The electronic device 40 includes a housing 40a having a window portion 22a for radiating the light emitted from the light emitting unit 22 on the front surface and accommodating a circuit board assembly related to the light emission of the light emitting unit 22. On the front surface of the housing 40a, the overhang portions 41 and 42 projecting forward from one side and above of the window portion 22a, and the recess 43 adjacent to the overhang portions 41 and 42 and where the window portion 22a is located. To prepare for. On the outermost front surface of the housing 40a, the upper overhang portion 41 and the side overhang portion 42 have a curved surface HC whose thickness is reduced at the left and right portions in the horizontal direction. A holding means for the cone 10 is provided on the rear surface of the housing 40a. The method of installing the electronic device 40 on the cone 10 is the same as that of the prior art, and the description thereof will be omitted.

In this embodiment, only the light emitting surface of the light emitting portion 22 of the electronic device 40 is lower than the front outermost surface of the housing 40a, that is, the overhang portions 41 and 42, and the upper overhang portion 41 and the side portion of the light emitting surface of the light emitting portion 22. It has the same height as the overhang portion 42 and has an uneven structure with respect to the concave portion 43. In order to realize this uneven structure, the components of the board (circuit board assembly) mounted on the electronic device 40 and the components built in the electronic device 40 are arranged separately according to the component height. That is, the parts having a high component height are arranged in the upper overhang portion 41 and the side overhang portion 42 of the light emitting surface of the light emitting unit 22, and the parts having a low component height are concentrated and collected in the vicinity of the light emitting surface of the light emitting unit 22. The heights of the light emitting surface (recessed portion 43) of the light emitting portion 22 and the front outermost surface (overhang portions 41, 42) of the housing 40a are provided with irregularities. As a result, the upper overhang portion 41 and the side overhang portion 42, that is, the oncoming lane side (oncoming vehicle OCC side) can be formed high, so that it is difficult for the driver of the oncoming vehicle OCC to see. Therefore, in this embodiment, the visibility changes depending on the position of the viewer, such as ensuring the visibility of the light emitting portion of the electronic device installed outdoors and making it difficult to see depending on the position facing the light emitting portion.

By adopting this structure, the light emitting surface of the light emitting unit 22 is less likely to be exposed to direct sunlight due to the influence of the upper overhang portion 41, and is likely to be shaded, so that the visibility of the light emitting unit 22 is improved. Further, since the side overhang portion 42 is on the oncoming lane side, it becomes difficult for the driver in the oncoming lane to see. Further, by mounting a component having a low component height inside the light emitting surface of the light emitting unit 22, the distance between the LED component on the substrate and the LED light guide lens (not shown) is shortened, and the brightness of the LED is reduced with less power consumption. It is also possible to secure.

In this embodiment, instead of the curved surface HC whose left and right portions become thinner in the horizontal direction, as shown in FIG. 4, the upper overhang portion 41 and the side overhang portion 41 are on the outermost front surface of the housing 40a. The portion 42 is the same as that of the first embodiment except that it has a curved surface HVC in which the left and right portions are thinned in the horizontal direction and the upper and lower portions are thinned in the vertical direction.

In this embodiment, instead of the curved surface HC whose left and right portions become thinner in the horizontal direction, as shown in FIG. 5, the upper overhang portion 41 and the side overhang portion 41 are on the outermost front surface of the housing 40a. The portion 42 is the same as that of the first embodiment except that it has a flat surface PL having a constant thickness in the horizontal direction and the vertical direction.

From the above, according to the above examples
1. 1. Since the upper overhang portion 41 is provided on the light emitting surface of the light emitting unit 22, it is difficult to be exposed to direct sunlight, and the visibility of the light emitting unit 22 is improved. By forming a concave-convex structure in which the light emitting surface of the light emitting portion is lowered and the upper portion thereof is raised, it is difficult to be exposed to direct sunlight and the visibility of the light emitting portion is improved.
2. 2. Since the side overhang portion 42 is provided on the light emitting surface of the light emitting unit 22, it is difficult for the driver in the oncoming lane to see and notice. By lowering the light emitting surface of the light emitting portion and raising the left portion (in the case of traveling on the left side), it is difficult for the driver in the oncoming lane to see.
3. 3. Since the distance between the LED component on the substrate and the LED light guide lens is shortened, it is possible to secure the brightness of the LED with less power consumption.
4. In the structure related to the visibility of the light emitting part of the equipment installed on the road during road construction, it is conceivable to form a thin eaves structure in order to improve the visibility of the light emitting part and prevent visibility from the oncoming lane. In the thin eaves structure, the cone may roll over, so the strength of the eaves is a concern. However, according to the present invention, there is no risk of damage or injury due to the damaged portion, and strength can be ensured in the structure for improving visibility.

In any of the embodiments, the width and thickness of the overhang portion in the housing can be secured, which is suitable for an antenna device and a wireless communication device.

In the above, all of the examples have been described using an example applied to a rectangular parallelepiped housing, but by chamfering the corners of the housing and changing the width and aspect ratio of the housing, the housings having various shapes can be used. It can also be applied to electronic devices that have a body.
