Description

[Detailed description of the invention] [Industrial application field] This invention can be integrated with architecture, construction materials such as paving blocks, tiles, etc., or can be used on the ground to indicate road intersections, vehicle stop lines, road shoulders, etc. This invention relates to a light emitting device that is directly installed.

[Prior art and its problems]

As shown in FIG. 3, a conventional ground-mounted light emitting device has a cylindrical main body 92 erected on a support 91 made of mortar or the like buried underground, and a male threaded portion 93 at the upper end of the main body 92. Transparent lens 94 that is screwed on
and a light-emitting body 95 housed within the main body 92 (see Japanese Patent Publication No. 54-9402).

However, in the above-mentioned ground-mounted light emitting device, the main body 92 is simply installed upright on the support 91;
The main body 92 is not completely moisture resistant.
Moisture enters through the opening at the lower end, shortening the life of the light emitter 95 and other internal structures.

Moreover, before installing the main body 92, it was necessary to provide a hole in which to bury the support 91, which is larger than the main body 92, making the installation work extremely complicated.

Furthermore, when replacing or maintaining the light emitting body 95, the transparent lens body 94 is removed, but at this time, it is considered that the transparent lens body 94 and the surrounding ground are in close contact with each other, so it is impossible to remove it. Furthermore, foreign matter such as earth and sand around the male threaded portion 93 may fit into the thread groove, causing damage to the lens body 94 and the main body 92.
It was impossible to make a strong screw connection.

[Purpose of this invention]

The present invention was devised in view of the above-mentioned purpose, and its purpose is to provide a light-emitting device that is extremely easy to install, replace and maintain the light-emitting body, and has excellent impact resistance and moisture resistance. It is something to do.

[Specific means to achieve the purpose]

The specific means taken by the present invention to achieve the above-mentioned object include: an inverted conical bracket with a step formed on the inner wall; a substrate positioned in the step and having a socket; It consists of a light emitter that is detachably attached to the socket, a cap body having a light-transmitting window that is screwed into the upper opening of the bracket, and a mold part that seals the lower opening of the bracket. be.

〔Example〕

Hereinafter, the light emitting device of the present invention will be explained in detail based on the drawings.

FIG. 1 is a cross-sectional structural diagram of the light emitting device of the present invention.

The light emitting device includes an inverted conical bracket 1, a substrate 2 disposed within the bracket 1, a light emitting body socket 3 provided on the substrate 2, a light emitting body 4 detachably connected to the socket 3, and a light emitting body 4 attached to the bracket 1. It is comprised of a mold part 5 that seals the lower end opening, and a cap body 6 that is screwed onto the upper end opening of the bracket 1.

The bracket 1 is made of a corrosion-resistant metal such as aluminum, stainless steel, etc., and its shape is approximately an inverted cone (with a cutout at the top) to prevent underground subsidence. A positioning step portion 13 for positioning the positioning member 2 is formed.
Further, a threaded portion 19 into which the cap body 6 can be screwed is formed in the inner wall portion 11 near the upper end opening 16.

The substrate 2 is made of an insulating material such as glass-epoxy, and has a shape that allows it to be inserted into the stepped portion 13 from the lower end opening 15 side of the bracket 1.

A light emitter socket 3 is arranged on the substrate 2, and a waterproof lead wire 31 for supplying power to the socket 3 extends from the substrate 2 and is buried underground through the lower end opening 15 of the bracket 1. It is connected to a control device and a power supply device (both not shown).

The mold part 5 is the lower end opening 15 of the bracket 1.
The material used for this purpose is to completely block moisture from entering, and the materials used include insulating adhesive resins such as epoxy and acrylic, and butyl rubber, which have excellent moisture resistance. As a result, the lead wire 31 is also completely covered, and the waterproof lead wire 31 is also fixed.

The light emitter 4 is attached from the upper end opening 16 side of the bracket 1, and is detachably attached to a predetermined position of the socket 3.

The cap body 6 has an upper end opening 16 of the bracket 1.
It is for sealing, and is constructed by mounting a light projection window 62 made of a transparent lens body in a metal frame 61. A threaded portion 63 formed on the outer peripheral surface of the metal frame 61 is screwed into the threaded portion 19 of the bracket 1, thereby connecting the cap body 6 and the bracket 1.
become one. Incidentally, in order to improve the moisture resistance between the cap body 6 and the bracket 1, an O-ring 64 is arranged at the abutting portion of the two members. Further, in order to disperse external stress applied from above the cap 6 to the bracket 1, the bracket 1 is provided with horizontal step portions 65 and 66 that come into contact with the cap 6.

The light emitting device configured as above is placed directly on the ground.
Alternatively, as shown in FIG. 2, a predetermined shape is embedded in a bracket fitting hole 71 formed in the paving stone block 7 via an adhesive 72 such as acrylic or epoxy resin.

In addition, attach the bracket 1 to the fitting hole 7 using the adhesive 72.
1, it is effective to provide a V-groove 14 around the outer wall slope 12 of the bracket 1.

In the light emitting device having the above structure, the light emitting body 4 can be easily replaced by removing the cap body 6.

Further, the external stress applied from above the cap body 6 is propagated to the bracket 1 from the horizontal step portions 65 and 66, and further to the approximately inverted conical outer wall slope 1 of the bracket 1.
Disperses underground from 2. As a result, the impact resistance is improved, and the bracket 1 can be installed with just one hole, making the installation work extremely easy.

Also, the bracket 1, the board 2 and the cap body 6
Even if the internal pressure of the space surrounding the light emitting body 4 increases due to heat or the like, the volume of the molded part 5 changes to absorb the pressure, which will cause great damage to the light emitting body 4 and the socket 3. It is possible to achieve a longer lifespan.

In the above example, the light emitting device was installed directly on the ground or on a block laid on the ground, but its uses are wide-ranging, such as installing it on various buildings, construction materials, and the side walls and ceilings of buildings. be.

[Effect of idea]

As described above, since the bracket of the light emitting device of the present invention has a substantially inverted conical shape, external stress from the cap body is dispersed and propagated to the fitting hole, making it difficult to maintain the installation position. impact resistance is improved. Further, the bracket can be installed by an extremely simple operation of forming a fitting hole into which the bracket fits and installing the bracket in the hole.

In addition, the light emitting body can be replaced and maintained by simply removing the cap screwed onto the threaded portion of the inner wall of the bracket, and the work can be performed with good reproducibility with less foreign matter adhering to the thread groove of the threaded portion.

Furthermore, the molded part and the O-ring can completely block moisture from entering the bracket, improving moisture resistance.
