An embedded marker lamp 2 having a lamp 4 built therein is mounted on the base 1 with bolts 3. The main body of the recessed type indicator light 2 is made of, for example, a high-strength aluminum alloy casting, and is solidly molded, and these tires slide or run on the indicator light when the aircraft is taking off and landing or when an automobile is running. I try not to damage it.

Further, a lamp 4 is provided on the body of the embedded marker lamp 2.
A light lead-out portion 5 for emitting light from the is provided. Although illustration is omitted, a reflecting mirror and a prism lens are provided between the lamp 4 and the light guiding portion 5, and the light from the lamp 4 is emitted in a predetermined direction through these. And
From the light lead-out portion 5, a wide vertical light is emitted in the vertical direction in the elevation direction and in a horizontal horizontal direction. Light derivation unit 5
Is provided, the main body of the embedded marker light 2 is slightly projected from the road surface. From this, the embedded marker light 2
The main body of the is formed with a tapered portion having a high central portion and inclined downward toward the peripheral edge so as not to hinder the traveling of an airplane or an automobile.

In addition, inside the embedded marker lamp 2, a secondary side 9 of a transformer 9 for outputting lighting power to the lamp 4 is provided.
b is arranged. Lighting power is output to the lamp 4 from the winding on the secondary side 9b of the transformer.

On the other hand, on the base 1, the primary side 9 of the transformer 9 is provided.
a is disposed, and the lighting power is output from the external terminal 7 to the winding on the primary side 9a through a wire (not shown). The wiring and the external terminal 7 output lighting power to the transformer 9 as a power output device. When the embedded marker lamp 2 is mounted on the base 1, the primary side 9a of the transformer 9 is
Is the secondary side 9b of the transformer 9 arranged in the recessed type indicator light 2.
And magnetically coupled to form a transformer 9. This allows the lamp 4 to move from the primary side 9a of the transformer 9 to the secondary side 9b.
It outputs the power for lighting.

FIG. 2 is a circuit diagram of a lighting power output circuit to the lamp 4 which is formed when the embedded guide light 2 is mounted on the base 1. The lamp 4 of the embedded guide light 2 is a transformer 9
The secondary side 9b of the transformer 9 is connected, and lighting power is output from the primary side 9a of the transformer 9 to the secondary side 9b.

FIG. 3 is an explanatory view of the iron core of the transformer 9, and FIG. 3 (a) shows an E-shaped iron core 10.
(B) shows the U-shaped iron core 12. Figure 3 (a)
Shows the state when the embedded marker lamp 2 is mounted on the base 1, and the primary side 9a and the secondary side 9b of the transformer 9 are shown.
E-shaped primary side iron core 10a and secondary side 1 provided in the
0b is a position where the embedded marker lamp 2 is faced with a predetermined gap when the embedded marker lamp 2 is mounted on the base 1.

A primary winding 11a and a secondary winding 11b are respectively wound around the central portions of the E-shaped iron cores 10a and 10b, and a magnetic circuit is provided between the E-shaped iron cores 10a and 10b via a gap. From the primary winding 11a to the secondary winding 11
Electric power is output to b.

On the other hand, when the embedded marker lamp 2 is removed from the base 1, the magnetic circuit between the E-shaped iron cores 10a and 10b via the air gap is not formed and the secondary winding from the primary winding 11a is not formed. The electric power is not output to the winding 11b.

Similarly, FIG. 3B shows a state in which the embedded marker lamp 2 is mounted on the base 1, and is provided on the primary side 9a and the secondary side 9b of the transformer 9. When the embedded marker lamp 2 is mounted on the base 1, the U-shaped primary iron core 12a and the secondary iron core 12b are facing each other with a predetermined gap.

2a and the secondary iron core 12b around which the secondary winding 11b is wound are configured so that a magnetic circuit is formed through an air gap. Therefore, since the electrical connection is insulated, rainwater does not infiltrate into the connection portion to prevent insulation failure.

Further, since the base 1 and the embedded marker lamp 2 are respectively provided with the primary side 9a and the secondary side 9b of the transformer 9 so that the transformer 9 can be separated, the replacement of the embedded marker lamp 2 is possible. Work can be done easily. Further, since the E-shaped iron core 10 or the U-shaped iron core 12 is used, the magnetic coupling force is increased, and it is possible to prevent disturbance to the magnetic circuit due to vibration or impact on the embedded marker light 2.

[0029]

As described above, according to the first aspect of the present invention, since the lamp and the power output device are electrically connected by the magnetic circuit of the transformer, the physical connection portion by the wiring is Absent. Therefore, the problem of insulation failure due to the influence of rainwater and the like is eliminated.

According to the second aspect of the invention, since the iron core of the transformer is formed in an E shape or a U shape, magnetic coupling between the primary side and the secondary side of the transformer can be properly performed, and loss due to magnetic leakage can be achieved. Can be minimized.
