Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ground-type beacon light at an airport that uses a reflector to project beam 11 light in a specific direction.

Conventionally, edge lights on runways are installed on the sides of the runway and beams only in the longitudinal direction of the runway.
Beacon lights that are emitted in such a way are difficult to be recognized from any direction other than the direction in which the light is emitted, and therefore vehicles traveling within the port may not notice the presence of the beacon lights and may come into contact with them and be damaged.

Further, as described in 7 above, since this type of light projects only in the longitudinal direction of the runway, it does not serve as a beacon light for aircraft approaching the airport while turning.

In response to this, a conventional system has been proposed in which a Fresnel lens is used to project light from the beam source in a predetermined direction and also to project light to the upper periphery (Registered Utility Model Publication No. 36).
No. 3707). However, the design and structure of this Fresnel lens were extremely complicated, and the cost was unavoidable.

The present invention has been made in consideration of the above circumstances, and it uses a reflector to obtain a beam source in a predetermined direction (:, by projecting light to the surrounding area, it is possible to safely and easily control the light from a turning aircraft). The object of the present invention is to provide an inexpensive terrestrial beacon light at an airport without the need for a complicated Fresnel lens. This will be explained with reference to the figure. (1) is a cover made of translucent glass, for example. This cover is formed, for example, in a cylindrical shape with an opening at one end, and the opening is attached to the substrate (2). . (3) is a light source provided on the cover (1), and is supported by a holding part (4) (2) provided on the substrate (2). (51 and (5) are reflectors, respectively). It has a light projection opening (6) at one end and a notch (7) at the other end, and the notch (7) is provided to face the light (3). These reflectors (5)
, are the notches (7) and (7) in (5) at a certain interval? It is necessary to have and arrange it. and the reflector (5)
, (5) each converts a part of the irradiated light from the light source (3) into a beam source from the light projection aperture (6) and projects the light. The remainder of the light emitted from the light source (3) is projected upward or sideways in FIG. 1 from the gaps between the reflectors (5), (5). In addition, the reflector (
5) and (5) are constructed to obtain a desired light distribution, such as a paraboloid of revolution or an ellipsoid of revolution. Also, the reflector (5)
, (5) has, for example, an extension piece (8) that extends outward from the light projection opening (6), and this extension piece (8) allows the end upright piece (9) of the support part (4) to However, other fixing methods are of course possible.

aα is a base that is erected, for example, on a runway or the like. This base aα can be formed into a cylindrical shape through which wiring (not shown) can be inserted. (11 is a support member, which is located between the base QO) 2 and the substrate (2). The joint surfaces of this support member Uυ and the base a■ are formed in a spherical shape that can slide on each other, and the base 00 of the support member Uυ
) can be adjusted (-), i.e.
In Figure 1 (2), the through hole (12
1 is formed 11F, and the screw inserted from the support member 01) side (wing nut in 131) (141Y) is tightened and fixed, and if the wing nut) (141'& loosened and moved the screw (131), the transparent The position can be adjusted within the range of the hole az. (L9 is the cover (11)
This is a metal fitting for fixing the substrate (2) and the substrate (2). However, the configurations of the base aα, the supporting member (one member, etc.) are not directly related to the present invention, and it goes without saying that other configurations may be used.

Next, we will discuss the effect. Of the light emitted from the light source (3), the source that enters the reflector (5), (5) through the notch (7) is converted into a beam source by the reflector (5), (5), and is projected. Light is projected from the light aperture (6). For example, it is used as an edge light for a runway.

On the other hand, the notch (7) of the reflector (5), (51), (
Light leaking from the gap 7) passes through the translucent cover (1) and is projected upward and around. Such light illuminates the area above and around the marker light, making it possible for vehicles traveling at the airport to recognize the presence of the marker light. This makes it possible to recognize the position of the runway.

In this example, the light emitting aperture (6) of the reflector (5)
) and the cover (1) may be provided with a filter. Further, the entire or arbitrary portion of the non-coupling portion with the light projection opening (6) of the cover (11) may be processed with 70 strokes or the like to diffuse the light.

3 and 4 show other embodiments. The same parts as in the first embodiment are given the same reference numerals, and their explanation will be omitted. In this embodiment, an auxiliary reflector (2Iv) is provided to reflect the source that goes from X5 (3) to the bottom surface of the cylindrical cover (1) sideways.According to such a configuration (2), It is possible to increase the amount of light irradiated to the side.In addition, when the direction of the irradiation is set outward and above the runway for the edge light, it can be recognized by navigation aircraft making a turning approach. However, the irradiation method of the auxiliary reflector is not limited to this, and the position of the auxiliary reflector is not particularly limited. .

It should be noted that the present invention can be modified in various ways other than the above embodiments. For example, the number of reflectors may be one. Furthermore, even when a plurality of light beams are provided, the same light distribution is not necessarily obtained. Further, the shape of the cover is not limited either, and may be a cylindrical one with a light blocking member provided on the end face.

As detailed above, the present invention has a light projection opening at one end,
Since a reflector having a notch at the other end is used, and the notch of this reflector is provided facing the light source, a beam source in a predetermined direction can be obtained from the light projection aperture, and The remaining light that does not enter the notch can illuminate the surrounding area, so vehicles traveling at the airport will not recognize the presence of the marker lights and will not come into contact with them. On the other hand, ℃ can also be used to recognize airports and runways.
Since it is not something that people are required to use, it has a simple structure and can be provided at a reasonable price.
