DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device provided with a globe.

[0002]

2. Description of the Related Art Heretofore, there has been a lighting device equipped with a truly spherical glass globe in a street light or the like. Spherical gloves are preferred and frequently used due to their simple design. In addition, a lighting device provided with a transparent spherical globe emits illumination light in a fairly wide range including the sky because there is no portion for controlling light emitted from the light source.

However, recently, obstacle light has become a social problem, and there is a demand for a lighting fixture that does not emit light in a direction other than a desired direction. In particular, there is a tendency for illumination light to be radiated to the sky.

[0004] Therefore, it is known to form a reflection film by vapor deposition of aluminum in the upper hemisphere portion of the inner surface of a spherical globe. With this glove, the problem of obstructive light in the sky direction can be solved. it can.

[0005] Further, there is a lighting fixture having a configuration in which annular louvers are arranged in multiple stages around a light source to suppress obstacle light.

On the other hand, there is a problem that glass gloves are easily damaged by stone throwing or the like.

[0007]

As described above, this type of conventional luminaire has problems that it emits obstructive light toward the sky and is easily damaged.

Further, a lighting apparatus having a reflective film in the upper hemisphere of a transparent glass globe has no problem of obstruction light toward the sky, but is easily broken.

Further, in a lighting fixture having a louver disposed in a glove, the glove must be removed first and then the louver must be removed in order to attach / detach a light source. Since it is necessary to increase the opening diameter of the glove, the design is restricted. If the glove is made of glass, there is also a problem of breakage.

[0010] As described above, there is no conventional lighting apparatus that solves all the problems of obstruction light in the sky direction, workability of attaching and detaching the light source, and damage to the glove.

According to the present invention, there is provided a lighting device which does not emit obstructive light toward the sky, easily attaches and detaches a light source, makes it harder to break the glove if necessary, and has a more elegant glove in design. It is intended to provide an instrument.

[0012]

According to a first aspect of the present invention, there is provided a lighting apparatus comprising: a base having a mounting portion at a lower end, a support portion in the middle, and at least a pair of arms rising from the support portion; A bowl-shaped translucent glove having a lower opening in contact with the upper end and opened and fixed between the arms; and a translucent glove which is covered with the translucent glove and fixed to the arm. A light-shielding cover in the shape of a bunk bowl that cooperates to form a glove; and a socket supported by a base.

In the present invention and each of the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

The lighting fixture of the present invention is suitable for outdoor lighting fixtures, especially garden lights, but is not limited thereto.
Suitable for street lights, brackets, etc. Furthermore, it is adapted for indoor use if necessary.

First, the base will be described.

The structure of the mounting portion at the lower end of the base is not limited as long as it is a portion that functions to mount the luminaire on a support or the like. However, when mounting on a pole,
Means such as forming into a cylindrical shape and fixing with a push screw can be used.

The supporting portion supports the light-transmitting globe by contacting the bottom surface of the light-transmitting globe, and can be waterproofly supported. However, it is not essential to provide waterproof support,
It is important to reliably drain rainwater that has entered the inside of the glove, and it is therefore preferable to form a drain hole in the bearing.

However, if light leaks from the drain hole, it is tempted by the light leaking from the drain hole, and insects easily enter the glove through the drain hole. Therefore, it is necessary to take light leakage preventing means.

The bearing is often formed integrally with the mounting part.

Next, at least one pair of arms is at least two
This means that there is only one arm, and three or more arms may be provided at equal intervals, for example. The arm portion stands up from the support portion, but may be formed integrally with the support portion, or may be formed separately and fixed to the support portion. And
The shape of the arm preferably conforms to the contour of the translucent glove.

When the arm is formed integrally with the support,
The base, the mounting part, the bearing part and the arm part can all be integrally formed by aluminum die casting.

In the case where the arm is formed separately from the support, the two may be fixed with a fixing tool such as a screw.
This also facilitates molding.

Next, the glove will be described.

[0024] The glove is configured to surround the light source with the translucent glove and the light shielding cover as main parts. The globe may have a true spherical shape or an elliptical spherical shape, but may have an arbitrary three-dimensional shape such as a square shape such as a cubic shape, a rectangular parallelepiped shape, an abacus ball shape, and a polygonal three-dimensional shape.

The upper end of the translucent globe, that is, the division line of the globe can be set at the center in the up-down direction of the glove, but can be shifted upward or downward from the center if necessary. Therefore, the position of the division line in the vertical direction of the glove is free.

The glove does not need to be composed of only the light-transmitting glove and the light-shielding cover. If the light-transmitting glove and the light-shielding cover constitute the main part of the glove, other secondary members are provided. May be interposed. For example, a ring body can be interposed between the translucent glove and the light-shielding cover. The ring body can be formed by molding or bending a light-shielding material such as a synthetic resin or metal.

When a ring body is interposed in the glove,
The ring body can be fixed to the light-shielding cover and then attached to the translucent glove. Further, the light-shielding cover can be attached to the ring body after the ring body is fixed integrally with the light-transmitting cover. Further, the ring body may be attached to the arm. When the latter configuration is adopted, the translucent glove may be sandwiched between the arm and the ring body.

Regarding the translucent glove The translucent glove is preferably made of a transparent, mechanically strong and transparent material such as an acrylic resin or a polycarbonate resin.
Also, the translucent glove may be mechanically reinforced glass.

The light-transmitting glove is not limited to a transparent material, but is made of a light-diffusing and transmissive material or a transparent material whose surface is processed to be light-diffusing and transmitting by sandblasting, prism molding, or the like. May be done.

Therefore, in the present invention, translucency means
Includes both transparent and light diffusive transmissive.

Further, the translucent glove may have a lower opening at the bottom surface and a bowl shape having an open upper end. The specific shape is not particularly limited, but may be substantially hemispherical. . In addition, it is desirable to form a concave groove on the outer surface of the translucent glove into which the arm of the base can be fitted.

Further, the light-transmitting glove has a lower opening in contact with a support portion of the base, and further has a groove between the arms when the light-transmitting glove has a groove. The arm is preferably fixed to the base in a state where the outer surface of the arm is fitted so that the outer surface of the arm is substantially flush with the translucent glove adjacent thereto.

As to the light-shielding cover, the material of the light-shielding cover is not limited as long as it is provided with a light-shielding property, but is preferably made of metal from the viewpoint that sufficient mechanical strength can be obtained. In the case of metal, a metal plate may be subjected to spat-drawing or deep-drawing by pressing, or may be cast as in aluminum die-casting.

The light-shielding cover covers the light-transmitting globe and forms a glove in cooperation with the light-transmitting glove. Therefore, the light-shielding cover is in the shape of a prone bowl. When trying to obtain a truly spherical globe in cooperation with the translucent globe, the light-shielding cover can be made substantially hemispherical. However, in the present invention, the shape of the glove is not limited to a true sphere as described above.

The light-shielding cover is fixed to the arm of the base. The fixing may be either direct or indirect. Directly means that the light-shielding cover is directly fixed to the arm by a fixing tool such as a screw. Indirect means that it is fixed to the arm via a member such as a bridge member or a ring body.

The light source and its relation will be described.

In the present invention, the light source used is not limited. For example, a light source such as a high-intensity discharge lamp such as a mercury lamp, a metal halide lamp, and a high-pressure sodium lamp, a compact fluorescent lamp, and an incandescent lamp can be used.

As the incandescent bulb, a general lighting bulb, a halogen bulb, a krypton bulb and the like can be used.

Therefore, an optimum socket and socket mounting position can be adopted according to the type of light source used and the power consumption.

Further, the socket only needs to be directly or indirectly supported by the base. Preferably, a socket mounting plate is fixed to a support portion of the base, and the socket is mounted on the socket mounting plate.

The operation will be described.

In the present invention, since the globe is composed mainly of a bowl-shaped light-transmitting glove and a cover-shaped light-shielding cover that covers the globe, the light-transmitting glove is fixed to the base in advance. be able to. The light source is attached and detached by removing the light shielding cover.

Therefore, since the open end of the translucent glove has a large diameter, the work of attaching and detaching the light source is easy. Also,
A light control member having an arbitrary structure and size such as a louver can be mounted around the light source as desired.

Further, the light-transmitting glove is easy to mount because the bottom surface abuts on the support between the arms of the base.

Further, the shape of the glove can be various shapes as well as a true spherical shape.

Furthermore, since the light-shielding cover is directly or indirectly fixed to the arm, and the translucent glove is fixed to the base, the glove can be mechanically firmly fixed.

Furthermore, since the upper half of the globe is formed by the light-shielding cover, it is possible to suppress the emission of obstacle light to the sky.

Further, by forming the light-transmitting glove with a synthetic resin having a high mechanical strength or the like and forming the light-shielding cover with a high-strength material such as a metal, the strength of the glove can be increased. For example, it can be made not to be easily damaged.

In the present invention, since the globe is a true sphere, the light-transmitting glove and the light-shielding cover can be formed substantially hemispherically. Here, a hemisphere does not need to be a complete hemisphere, but allows one to occupy a larger portion of the sphere than the other. Due to optical requirements, the translucent globe occupies more of the sphere than the light-shielding cover, that is, the dividing line can be positioned above the vertical center of the glove.

According to a fourth aspect of the present invention, in the lighting device according to any one of the first to third aspects, the light-shielding cover has a lower end peripheral edge fixed to the arm of the base. .

In order to fix the light-shielding cover to the arm, a portion of the lower end periphery of the light-shielding cover facing the arm can be recessed from the outside except for the end face. Then, the light-shielding cover can be easily fixed to the arm by screwing the light-shielding cover onto the upper end surface of the arm. However, if necessary, it may be fixed by a structure other than the above.

According to a fifth aspect of the present invention, there is provided the lighting device according to any one of the first to third aspects, wherein the light-shielding cover is fixed via a bridge member having both ends fixed to the arm portion of the base. It is characterized by having.

In the present invention, the bridge member is a member for bridging a plurality of arms facing each other, and can be generally formed of an elongated metal plate. Both ends of the bridge member are fixed to the end surfaces of the arms by, for example, screws, and a light-shielding cover is fixed to an intermediate portion thereof. The light-shielding cover can be fixed by screwing a screw into the bridge member from the center thereof, that is, from the top of the light-shielding cover.

If necessary, the bridge member can also serve as a reflector. That is, a desired reflector is fixed between the arms so as to be located above the light-transmitting glove, the light-shielding cover is covered with the light-transmitting cover so as to cover the reflector, and the reflector is formed using, for example, bolts. Can be fixed.
