Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recessed marker light such as an aviation beacon light, and relates to a configuration for embedding and bonding a lamp body.

[Prior art] This type of conventional embedded type marker light was developed in 1963.
As described in Publication No. 13130, a method of embedding and fixing the lamp body into an embedding hole formed in concrete or asphalt formed on a paved surface using adhesive has been explored, but conventional methods In the case of a recessed sign light, the bottom surface of the light body is formed into a flat shape, and in the case of a road sign body, the road surface and the light body are bonded with adhesive as described in Japanese Utility Model Publication No. 36-11313. Therefore, a structure in which radial grooves are formed is known.

[Problem that the invention seeks to solve]

In the conventional recessed sign light mentioned above, the bottom surface of the light body is formed flat, and the grooves on the bottom surface of the road sign body are formed at the same depth, so there is no air between the light body and the adhesive. There was a problem that air bubbles were formed in the adhesive without being ejected, making the attachment of bushes uncertain, and the lamp body did not have a rotation stopper, which could cause the lamp body to move freely.

The present invention was made in view of the above-mentioned drawbacks, and by forming a concave groove in the bottom outer surface of the lamp body, the depth of which gradually increases from the middle part of the bottom outer surface toward the outer circumference green, thereby forming a groove between the lamp body and the adhesive. To provide a recessed indicator light in which the air between the parts is smoothly discharged, no air bubbles are formed, the adhesive area is increased, and the lamp body is prevented from rotating and is reliably embedded and fixed. . [
Means for Solving the Problems] The embedded marker lamp of the present invention includes a lamp body having a transparent window and embedded in the road surface, and a lamp body disposed inside the lamp body and emitting light from the transparent window. A light source is provided, and a concave groove portion is formed on the outer surface of the bottom of the lamp body, the depth of which gradually increases from the middle portion of the outer surface of the bottom toward the outer circumference.

[Effect]

In the embedded type marker light of the present invention, the bottom of the hole for embedding formed in the road surface is filled with a bush adhesive such as epoxy resin, and when the light body is stored in the hole, the adhesive is absorbed into the recess on the outer surface of the bottom of the light body. invades the groove,
Air between the adhesive and the lamp body is discharged to the outside by the inclination of the groove.

Next, the gap between the outer peripheral surface of the lamp body and the hole is filled with a joint material such as asphalt. When the light source inside the lamp body embedded and fixed in this manner is turned on, light is emitted from the transparent window.

〔Example〕

Next, the structure of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a lamp body, which is composed of a holder 2, a lower case 3, an upper case 4, and a base 5. The holder 2 is formed into a flat cylindrical shape by casting iron, aluminum, etc., and an annular holder 6 is formed protruding from the lower part of the inner periphery of the holder 2 . The lower box 3 is made of cast metal such as iron or aluminum, and the open green part has a holding part 6 of the holding body 2.
An engaging edge 7 is formed to be engaged with.

The upper case 4 is made of cast iron, aluminum, or the like, and has an outer diameter that is iron-fitted to the holder 2.

A through-hole window 8 is formed on the front surface of the upper case 4.
The upper case 4 and the lower case 3 are connected via an annular base 9 with screws (not shown).
An optical system unit housing section 10 is formed inside. Further, an annular mounting plate 11 attached to the base plate 9 is fixed to this storage part 1. Further, on the bottom outer surface of the base 5, which is the lower surface of the lamp body 1, ribs 12 are formed radially from the middle part toward the outer periphery, and between the ribs 12, the depth becomes gradually deeper toward the outer periphery. A groove portion 13 is formed.

Further, a support edge 14 for supporting the holder 2 is formed on the upper part of the base 5 along the periphery of the upper closed portion. Further, 15 is an annular light control body disposed along the inner circumference of the upper case 4 and held between the upper case 4 and the base 9;
Molded from glass.

Next, 16 is a light source such as a halogen lamp,
It is attached to a socket 17 attached to the front mounting plate 11 so as to face the through-hole window 8 .

Further, reference numeral 22 denotes a reflecting plate, which has a reflecting surface in the form of a rotating feature surface or a spheroidal surface, is operatively disposed with respect to the lamp 16, and is fixed to the mounting plate 11.

Next, the operation of this embodiment will be explained. The bottom of the embedding hole 18 formed on the road surface 201 is filled with an adhesive 19 such as epoxy resin, and when the lamp body 1 is housed in the hole 18, the adhesive 19 is formed between the ribs 12 on the lower surface of the base 5. Concave groove part 13
The air between the adhesive 19 and the base 5 is discharged to the outside due to the inclination of the groove 13.

Next, the gap between the outer peripheral surface of the lamp body 1 and the hole 18 is filled with a joint material 21 such as asphalt. When the lamp 16 in the lamp body 1 embedded and fixed in this manner is turned on, the light passes through the light control body 5 and is emitted from the transparent window 8.

〔Effect of the invention〕

According to the present invention, since a concave groove is formed on the outer surface of the bottom of the lamp body, the depth of which increases gradually from the middle part toward the outer periphery, the lamp body can be embedded in a hole formed in the road surface by filling the hole with adhesive. When fixing, the air between the adhesive and the lamp body is discharged along the slope of the concave groove, preventing air from entering the adhesive as bubbles, ensuring that the lamp body is firmly attached. The adhesive enters the concave groove to ensure that the lamp body is prevented from rotating, the lamp body is firmly fixed, and the structure is simple and can be obtained at low cost without increasing the number of parts.
