[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lighting apparatus including a globe.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a lighting fixture provided with a spherical glass globe in a street lamp or the like.
Spherical gloves are preferred and used frequently because of their simple design. And since the lighting fixture provided with the transparent spherical globe has no part which controls the light radiated | emitted from a light source, it radiates | emits illumination light in a fairly wide range including the sky.
[0003]
However, recently obstructive light has become a social problem, and the appearance of lighting fixtures that do not emit light in directions other than the desired direction is desired. In particular, it tends to be avoided that illumination light is emitted to the sky.
[0004]
Therefore, it is known that a reflective film is formed by vapor deposition of aluminum on the upper hemisphere portion of the inner surface of a spherical globe. If this globe is used, the problem of obstructing light in the sky direction can be solved.
[0005]
Further, there is a lighting fixture configured to suppress obstacle light by arranging annular louvers around the light source in multiple stages.
[0006]
On the other hand, glass globes have a problem that they are easily damaged by stones or the like.
[0007]
[Problems to be solved by the invention]
As described above, this type of conventional lighting fixture has problems that it emits obstacle light in the sky direction and is easily damaged.
[0008]
Moreover, the lighting fixture provided with the reflective film on the upper hemisphere of the transparent glass globe does not have a problem of obstructive light in the sky direction, but is easily damaged.
[0009]
Furthermore, in a lighting fixture with a louver in the glove, in order to attach and detach the light source, the glove must first be removed and then the louver must be removed. Since it is necessary to increase the diameter, there are restrictions on the design. Moreover, if the glove is made of glass, there is a problem of breakage.
[0010]
As described above, there is no conventional lighting fixture that has solved all of the problems of obstacle light in the sky direction, workability of attaching and detaching the light source, and the problem of damage to the globe.
[0011]
The present invention provides a luminaire that does not radiate obstruction light in the sky direction, is easy to attach and detach a light source, and is less likely to break the globe if necessary, and further includes a design-friendly glove. The purpose is to do.
[0012]
[Means for achieving the object]
The lighting fixture of the invention of claim 1 is provided with a base having an attachment portion at the lower end, a support portion and at least a pair of arms raised from the support portion in the middle; a lower opening in contact with the support portion at the lower portion, and an upper end A hook-shaped translucent glove that is opened and fixed between the arms, and covers the translucent glove and is fixed to the arm and forms a glove in cooperation with the translucent glove And a socket supported by the base.
[0013]
In the present invention and each of the following inventions, the definitions and technical meanings of terms are as follows unless otherwise specified.
[0014]
Although the lighting fixture of this invention is suitable for an outdoor lighting fixture, especially a garden light, it is not limited to this. Applicable to street lights and brackets. Furthermore, it can be adapted for indoor use if necessary.
[0015]
First, the substrate will be described.
[0016]
The structure of the attachment part at the lower end of the base body is free as long as it is a part that functions to attach a lighting fixture to a column or the like. However, when attaching to a support | pillar, means, such as forming in a cylinder shape and fixing with a push screw, can be used.
[0017]
The support portion is a portion that supports the translucent glove by contacting the bottom surface of the translucent glove and can be supported in a waterproof manner. However, it is not indispensable to support in a waterproof manner, and it is important to surely drain rainwater that has entered the inside of the glove, and therefore it is preferable to form a drain hole in the support portion.
[0018]
However, if light leaks from the drain hole, it is attracted by the light leaking from the drain hole, and insects can easily enter the glove from the drain hole. Therefore, it is necessary to take measures to prevent light leakage.
[0019]
In many cases, the support portion is formed integrally with the mounting portion.
[0020]
Next, at least a pair of arm portions means that there should be at least two arm portions, and three or more arm portions 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 an arm part preferably corresponds with the outline of a translucent glove.
[0021]
When the arm part is formed integrally with the support part, the base, the mounting part, the support part and the arm part can be integrally formed by aluminum die casting.
[0022]
Moreover, when forming an arm part separately from a support part, what is necessary is just to fix both with fixing tools, such as a screw, and, thereby, shaping | molding becomes easy.
[0023]
Next, the glove will be described.
[0024]
The globe is configured to surround the light source with the translucent globe and the light shielding cover as main parts. The globe can have a true spherical shape or an elliptical spherical shape, but can have an arbitrary three-dimensional shape such as a square shape, a cubic shape, a rectangular parallelepiped shape, an abacus ball shape, a polygonal solid shape, or the like.
[0025]
The upper end of the light-transmitting glove, that is, the dividing line of the glove can be set at the center in the vertical direction of the glove, but can be shifted to the upper side or the lower side if necessary. Therefore, the position of the dividing line in the vertical direction of the globe is free.
[0026]
In addition, the globe does not need to be composed only of the light-transmitting globe and the light-shielding cover. If the light-transmitting globe and the light-shielding cover constitute the main part of the globe, other secondary members are interposed. It may be. For example, a ring body can be interposed between the translucent globe and the light shielding cover. The ring body can be formed by molding or bending a light shielding material such as synthetic resin or metal.
[0027]
When the ring body is interposed in the globe, the ring body can be fixed to the light shielding cover and then attached to the translucent globe. Moreover, after fixing a ring body integrally with a translucent cover, a light shielding cover can also be attached to a ring body. Furthermore, you may attach a ring body to an arm part. When the latter configuration is adopted, the translucent glove can be sandwiched between the arm portion and the ring body.
[0028]
About translucent globe
The translucent globe is preferably made of a transparent material having a high mechanical strength such as an acrylic resin or a polycarbonate resin. The translucent globe may be a mechanically tempered glass.
[0029]
In addition, translucent globes are not limited to transparent materials, but are manufactured from light-diffusing and transparent materials or transparent materials that have been processed to light-diffusing properties by sandblasting, prism molding, etc. It may be.
[0030]
Accordingly, in the present invention, the term “translucent” includes both transparent and light diffusive transparency.
[0031]
Furthermore, the translucent globe may have a bowl shape having a lower opening on the bottom surface and an open upper end, and its specific shape is not particularly limited, but can be substantially hemispherical. Further, it is desirable to form a concave groove in which the arm portion of the base body can be fitted on the outer surface of the translucent globe.
[0032]
Furthermore, the translucent glove has a lower opening in contact with the support portion of the base, and when the concave groove is formed in the translucent glove between the arm portions, the arm portion is in the concave groove. Preferably, the arm portion is fixed to the base body in a state of being fitted so that the outer surface of the arm portion is substantially flush with the light transmitting globe adjacent thereto.
[0033]
About shading cover
The material of the light-shielding cover is not limited as long as it has light-shielding properties, but is preferably made of metal in that sufficient mechanical strength can be obtained. In the case of metal, the metal plate may be deep drawn by a spatula or press, or cast like an aluminum die cast.
[0034]
In addition, the light shielding cover covers the light transmitting globe and forms the globe in cooperation with the light transmitting globe. Therefore, the shading cover has a face-down shape. When trying to obtain a true spherical glove in cooperation with the translucent glove, the light shielding cover can be formed in a substantially hemispherical shape. However, in the present invention, the shape of the globe is not limited to a true sphere as described above.
[0035]
Further, the light shielding cover is fixed to the arm portion of the base body, but the fixing may be either direct or indirect. Direct means that the light shielding cover is directly fixed to the arm portion by a fixing tool such as a screw. Indirect means to fix to an arm part via members, such as a bridge member, or a ring body.
[0036]
The light source and its relation will be described.
[0037]
In the present invention, the light source used is not limited. For example, light sources such as high-intensity discharge lamps such as mercury lamps, metal halide lamps, and high-pressure sodium lamps, compact fluorescent lamps, and incandescent lamps can be used.
[0038]
As the incandescent bulb, a general lighting bulb, a halogen bulb, a krypton bulb, or the like can be used.
[0039]
Therefore, an optimal socket and socket mounting position can be employed according to the type of light source used and the power consumption.
[0040]
Furthermore, the socket should just be supported by the base | substrate directly or indirectly. Preferably, the socket mounting plate is fixed to the support portion of the base, and the socket is mounted on the socket mounting plate.
[0041]
The operation will be described.
[0042]
In the present invention, the glove is composed of a bowl-shaped light-transmitting glove and a cover-shaped light-shielding cover that covers the glove, so that the light-transmitting glove can be fixed to the base in advance. . The light source is attached and detached by removing the light shielding cover.
[0043]
Therefore, since the open end of the translucent globe has a large diameter, it is easy to attach and detach the light source. In addition, a light control member having an arbitrary structure and size such as a louver can be mounted around the light source as desired.
[0044]
In addition, the translucent globe is easy to mount because the bottom surface abuts the support portion between the arm portions of the base.
[0045]
Furthermore, the shape of the globe can be changed to various shapes as well as a spherical shape.
[0046]
Furthermore, since the light shielding cover is directly or indirectly fixed to the arm portion and the light transmitting glove is fixed to the base, the glove can be mechanically firmly fixed.
[0047]
Furthermore, since the upper half part of the globe is constituted by the light shielding cover, it is possible to suppress the emission of obstacle light to the sky part.
[0048]
Furthermore, the strength of the glove can be increased by forming the light-transmitting glove with a synthetic resin having a high mechanical strength and the light shielding cover with a material having a high strength such as metal. It is also possible to make it not damaged.
