Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) TECHNICAL FIELD The present invention relates to terrestrial beacon lights for airports.

(Prior Art) A conventional terrestrial marker light installed at an airport is composed of a marker light body housing an optical system and a base for fixing the body to the ground. If these marker lights are classified according to their basic light distribution patterns, there are unidirectional types, bidirectional types, and all-round types.

The structure of the marker light body and its attachment differs for each light distribution pattern. Furthermore, if classified according to the installation location, there are multiple types such as approach lights, terminal lights, runway edge lights, taxiway nails, etc. Each type has different desired projection angles and optical system characteristics, so the structure and specific arrangement are different. The light is different.

For this reason, in the past, marker lights were manufactured separately to suit each purpose, making it complicated to adjust the projection angle and optical system. Then, the light projection angle and the optical system related to the light distribution characteristics had to be adjusted again, and because the workability was poor, inspection and replacement work was troublesome and took a long time.

In addition, although it is not an airport beacon light, it is
There were indicator lights as shown in the issue.

This product does not pass the wire through the ball shaft (8 shown in Figure 1 of the Publication of Japanese Patent Publication No. 24-2274), so the wire (14 shown in Figure 1 of the same publication) is not exposed outside the indicator light. There is a danger that the wires may break due to external force.

(Problems to be Solved by the Invention) The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and an object of the present invention is to provide a ground-type beacon light for airports that is safe and easy to maintain.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an airport beacon light that includes: a base having a common specification that is fixed to the ground; a support portion that is attached to the base so that its position can be adjusted; The marking lamp main body is detachably attached to the support part, an electric wire for supplying electric power to the marking lamp main body, and a fixing means fixed to the base.

The base has a cylindrical shape with a hollow part for passing electric wires from the lower part to the upper part, and the lower part is directly or indirectly fixed to the ground, and the upper part has a recessed part along a substantially spherical surface.

The support part has a convex part on the lower part that engages with the recessed part in a position-adjustable manner, has a first hole for passing the electric wire at the substantially lowermost part, and has a holder on the upper periphery for attaching the indicator light main body. It has a seat.

The marker light main body has a second hole corresponding to the first hole in the substantially central part of the bottom surface, and a base body whose bottom periphery is removably attached in close contact with the receiving seat of the support section; and a light source housed in the space formed by the light projecting part and the base body and energized by the electric wire, each of which imparts the desired optical characteristics. The bottom peripheral edge of the base body is removably attached to the receiving seat of the support portion. It houses an optical system that has the required optical characteristics. The optical characteristics of the optical system include, for example, one direction, two directions, and all-around direction, but various other characteristics such as light distribution characteristics, light output, light color, etc. can be applied.

The fixing means contributes to fixing the support part to the base after adjusting the projection angle by relatively adjusting the position between the convex part and the concave part.

In the present invention, the shape and specific structure of the base and the support part are arbitrary. Furthermore, the marker light main body can have any structure including the structure for attaching it to the support part. What is required is that the position between the base and the support is adjustable for adjusting the projection angle.

(Function) According to the present invention, the base is attached to the ground, and then the support section is attached to the base. Thereafter, the base of the marker lamp body, whose optical system has been adjusted in advance, is attached to the support section. After mounting in this manner, positional adjustment is performed between the base and the support portion to adjust the projection angle. Of course, the base of the marker light body may be attached to the support section in advance, and then the support section may be attached to the base. Note that the electric wire is connected to the light source from inside the marker lamp, that is, from the bottom of the base, through the first hole and the second hole. The means for connecting the electric wire to the light source is arbitrary.

The present invention provides, for example, runway lights in which bidirectional marker lights are used, approach centerline lights in which unidirectional marker lights are used, approach cross spar lights, approach side row lights, terminal lights, terminal auxiliary lights,
It can be applied to terminal lights, taxiway lights that use all-round marker lights, approach lights, etc.

In addition, the projection angle can be easily adjusted between the concave part of the base and the convex part of the support part, and if the optical adjustment of the indicator light body is done in advance at the factory, the projection angle can be easily adjusted at the site. It is easy to understand that all that is required is adjustment and attachment to the indicator light body and support. In addition, it is basically not necessary to adjust the projection angle when the marker light body is removed from the support and a new marker light body is installed, or when the marker light body is reinstalled after an inspection. Needless to say, there is no harm in implementing it.

Further, the internal space of the marker light body communicates with the outside only through the first hole at the approximate center of the bottom surface of the base, while the support part communicates with the outside only through the second hole at the bottom. By closely attaching the peripheral edge of the base and the receiving seat of the support, measures such as waterproofing can be easily achieved. Furthermore, since the electric wire is routed from the bottom of the base of the marker light via the second hole, first hole, and hollow part inside the marker light, if the electric wire is routed underground, the marker light Signal lights can be turned on without exposing electric wires to the outside.
