Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an aviation beacon light system disposed on the landing surface of an aircraft such as a helicopter-1 airplane.

(Prior Art) Conventionally, in such a system, a plurality of floodlights that illuminate the landing surface and a plurality of boundary lights that show the outline of the landing surface are separately arranged around the landing surface, and the aircraft that is about to land is illuminated. Pilots inside the aircraft were informed of their general location from a distance using boundary lights, and at close range, the landing surface illuminated by floodlights informed them of the distance between the bamboo land surface and the aircraft.

(Problems to be Solved by the Invention) However, such a system requires a floodlight and a boundary light, resulting in high cost.

In addition, boundary lights have a horizontal range of 360 degrees and an elevation angle (
A plane parallel to the landing surface is defined as 0 degrees, and a line perpendicular to this plane is defined as 90 degrees. ) Although the light is projected in the range of 0 to 30 degrees, the light emitted from the lamp in the boundary light with an elevation angle of 30 degrees to 90 degrees is not particularly required.

The present invention has been made in view of the above problems, and its purpose is to provide an aviation beacon light system that is lower in cost than conventional ones.

[Structure of the Invention] (Means for Solving the Problems) The aviation beacon system of the present invention includes a plurality of light sources arranged along the circumference of an aircraft landing surface, a light source inside, and light generated by the light source. A marker light having a first optical means for outputting the light to the outside at an elevation angle of approximately 0 to 30 degrees; The angle of depression (if the plane parallel to the landing surface is 0 degrees, it will be 90 degrees in the vertical direction),
The landing surface is characterized by comprising second optical means for illuminating the landing surface.

(Function) By having a beacon light that incorporates the second optical means for illuminating the landing surface and the first optical means with an elevation angle of 0 to 30 degrees, the light can be used for both purposes, resulting in a low-cost system. can be provided.

(Example) A first example of the present invention will be described with reference to FIGS. 1 and 3. In FIG. 3, Y is the landing surface of the aircraft, A is the base, B is the support part, and C is the main body housing the optical means.

The base A has a spherical number ([I part 2
The digit part 2 has a pair of elongated holes 4. The threaded portion can be attached to the circumferential surface of the landing surface Y via a ball or other part provided upright on the landing surface Y or directly to the circumferential surface of the landing surface Y. Further, the inside of the cylindrical portion is hollow, and the electric wires]a and 1a can be inserted therethrough.

The support part B has a spherical mounting part 10 corresponding to the mounting part 2 of the base A, and further has an elliptical hole in the first part JO corresponding to the elongated hole 4. (not shown) is provided.

The main body C is mounted on the base A having such a structure and the support part B attached to the base A.

The main body C has a through hole 30 in the center, a substrate 31 that can be attached to and detached from the support section B, and a cylindrical light-transmitting cover that is open at one end and is attached to the substrate 3I. 32 and
A light source, for example, a halogen bulb 33, is inserted through the transparent hole 30 of the substrate 31 and detachably attached from the non-cover side of the substrate 31, and a light source 33 is provided opposite to the light source 33 to project the irradiated light. An umbrella-shaped upper reflector 34a and an umbrella-shaped lower reflector 34b made by pressing a disc.
and a band-shaped fixture 40 for removably attaching the board 31 and the cover. The interior of the main body C, which has a light emitting opening in the entire circumferential direction, is comprised of a polarizing plate 35 that bends the output light diagonally by 0 to 5 degrees, and a support part 36 that supports this polarizing plate 35. Second optical means 3
7 is attached, and a plurality of lights are arranged at equal intervals around the landing surface Y, and each main body C is attached to the landing surface so that the second optical means 37 illuminates the landing surface Y. It is located on the Y side. Note that the marker lights disposed near the corners of the landing surface Y are oriented toward the center of the landing surface when compared with other marker lights in the direction of light projection at the corners. The direction of the corner light projection of the other marker lights is perpendicular to the sides of the landing surface.

By doing this, it will be easier to install the marker lights. However, in order to illuminate the landing surface more efficiently, it is preferable to direct the light emitted from the corners of all the marker lights toward the center of the landing surface.

In this embodiment, a type of lighting equipment is used to indicate the landing surface direction and 0 to 3
It is possible to project light in the direction of an elevation angle of 0 degrees, and as a whole system, the lights are arranged around the entire circumference of the landing surface, so when the landing surface is viewed from a distance, the output light of any one of the lights will be the same no matter where you look at the landing surface. is recognized, so there is no practical problem.

The second optical means is not limited to a polarizing plate, and may be any lens, reflector, or other device as long as it can control light in a direction different from the main illumination direction.

A second example will be described.

The second embodiment is a marker light having a light source 330 built into the first optical means Fresnel lens shaped cover 320. Like the first embodiment, this one mainly distributes light in 360 degrees, and includes a reflecting plate 350 constituting the second optical means.
The light is projected at an angle of 0 to 5 degrees.

A plurality of these marker lights are arranged so as to project light onto the landing surface Y at an angle of 0 to 5 degrees. In this embodiment, the second optical means is composed of a reflector 350 and a reflector supporting member 360, but for example, the second optical means can be formed by attaching a lens or a vapor-deposited reflective film to the inner surface of the cover. It may be configured.

The second optical means of the present invention as described above can of course be applied to systems other than those shown in the above embodiments. For example, DESM1's product name RL30. ADB product name 0P200-H,
REE-2-1, 50, BBT product name BN-LE,
Regarding EB/IA, etc., when the second optical means is not used, the light is projected at an elevation angle of 0 to 30 degrees.
It is only necessary to arrange the optical means such that the light is projected at an angle of 0 to 5 degrees.
