DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizont light as an illuminating device for illuminating a background wall in a stage or a studio, and more particularly to a reduction in the number of parts and a simplification of a manufacturing process to reduce the overall cost. Horizon Light that made possible.

[0002]

2. Description of the Related Art Conventionally, a horizont light is generally used as a lighting device for illuminating a background wall (also referred to as a horizont surface) of a stage or a studio. Such a horizont light is usually adjusted by operating a light control device for controlling the brightness of the illumination so as to have an optimal brightness according to a purpose of use (scene). This allows
By providing illumination light having the optimal brightness and color according to the scene on the background wall surface, it is possible to more effectively produce an event on the stage or in the studio.

[0003] Such a horizont light includes an upper horizont light (also referred to as UH) that illuminates the background wall surface from above and a lower horizont light (also referred to as LH) that illuminates from below. FIG. 3 shows a lighting system for a stage, a studio, or the like using such various horizont lights.

In a lighting system shown in FIG. 3, a horizont sheet suitable for projecting illumination from a horizont light is provided on a background wall such as a stage or a studio. Illumination light from a plurality of upper horizont lights 10a and lower horizont lights 10b is applied.

The upper horizont light 10a is installed at a predetermined position by being fixed to a light hanging baton 2 suspended from the ceiling via a hook (not shown). On the other hand, the lower horizont light 10b
Alternatively, a floor of a studio or the like is installed at a predetermined position of a place commonly called a pit formed to be depressed near the horizont surface.

[0006] These horizont lights 10a, 10b
Are provided with various color filters of R, G, B by a filter holder mounted on the main body, respectively, and are arranged in this R, G, B color order. Thus, by adjusting the brightness of the illumination light source of each horizont light, the background wall surface, that is, the horizont surface is projected so as to be in an illumination state according to the scene (for example, an illumination state like a sunset scene). And a further effect can be obtained.

FIG. 4 is a configuration diagram showing an example of the above-mentioned horizont light. The configuration of the common part of the upper horizont light and the lower horizont light will be described with reference to FIG.
As shown in FIG. 3, a substantially hexagonal trapezoidal housing body 11 formed of a metal plate and having an opening for transmitting illumination light, a detachably attached to the housing body 11, and a color filter 16 attached And a filter holder frame 14 formed of a metal plate so as to provide an opening for accommodating the filter holder 16.

A lamp (for example, a halogen lamp) 12 as an illumination light source is provided in the housing body 11.
A pair of sockets 13 for mounting the lamps 12 are provided on both side surfaces of the housing body 11. In addition, a plurality of exhaust ports 11a, commonly called “yoroido doors”, are formed on the upper and lower surfaces on the rear side of the housing body 11. In other words, although not shown, the plurality of exhaust ports 11 on the rear side upper surface
a, the gas whose temperature rises due to the heat generated by the emission of the lamp 12 is exhausted to the outside, and the outside air is sucked in through a plurality of exhaust ports 11a (see the drawing) on the lower surface on the rear side, thereby providing the illumination light source. The lamp 12 is cooled. Further, the shape of the exhaust port 11a is not a normal through-hole, but the exhaust port 11a is formed such that the extending surface of the main body metal plate projects from the surface position of the main body metal plate and has an opening. Has formed. That is, a special and complicated molding operation is required instead of an easy molding operation for simply providing a through hole.

On the other hand, the filter holder frame 14 is formed in a frame shape separately from the housing main body 11 as shown in the figure, and is provided with various color filters 17 of RGB. The holder 16 is housed in the frame through the opening. Further, a reflection plate 15 for reflecting light emitted from the lamp at an optimum angle when the filter holder frame 14 is assembled with the housing body 11 is attached to the filter holder frame 14. The reflecting plate 15 is formed by a single plate-like reflecting member having an appropriate curve near the lamp 12 and having an elliptical shape facing downward in the drawing.

Next, a method of assembling the horizont light will be described.

When assembling the above-described horizont light, first, the reflection plate 15 is attached to the filter holder frame 14 in advance.
Then, the filter holder frame 14 is mounted on the front surface of the housing body 11 having an opening.

In this case, the filter holder frame 14 is
Then, a screw hole 14a provided at a predetermined position of the filter holder frame 14 and a screw hole 11b provided at a predetermined position of the housing body 11 are screwed with a screw. Combine. Thereby, the filter holder frame 14 is mounted on the housing body 11. The lamp 12 is removed in advance, and is mounted on the socket 13 after the mounting of the filter holder frame 14.

After that, the assembled horizont light 10 is installed at a position corresponding to the purpose, and the filter holder 17 with the color filter 17 of the corresponding color is housed in the opening of the filter holder frame 14. The filter holder 17 may be stored in advance.

The horizont light 1 thus installed is
In the case of 0, at the time of illumination, after the light emitted from the lamp 12 is reflected by the reflection plate 15, the light is transmitted through the surface of the color filter 17 through the opening of the housing body 11 to irradiate the horizont surface shown in FIG. By doing so, it plays a role as a horizont light.

However, in such a conventional horizont light, since the housing body 11 and the filter holder frame 14 have a separate structure as described above, the number of related parts is large, and the assembling work is complicated. Will be. Further, since the exhaust port of the housing body 11 requires a special manufacturing process, the number of manufacturing processes such as a bending process of the housing body itself also increases. For this reason, there has been a demand for a reduction in the cost of the entire lighting system, but the manufacturing cost is high in manufacturing the horizont light, and the cost cannot be reduced. there were.

Further, the reflection plate 1 greatly affects the light emission characteristics.
6 is attached to the filter holder frame 14, so that when assembled, the socket 13 and the socket 13 are arranged in consideration of the positional relationship with the reflector 16 so as to obtain optimal emission characteristics. There is also a problem that a slight shift may occur between them, which may adversely affect the light emission characteristics.

[0017]

As described above, in the conventional horizont light, the housing body and the filter holder frame have a separate structure, so that the number of parts is increased and the assembling work is accordingly performed. Since it becomes complicated, and the exhaust port of the housing body 11 requires a special manufacturing process,
Since the number of manufacturing steps, such as the step of bending the housing body itself, also increases, the manufacturing cost becomes high in manufacturing the horizont light, and the cost cannot be reduced. was there.

Further, the reflection plate 1 greatly affects the light emission characteristics.
6 is attached to the filter holder frame 14, so that when assembled, the socket 13 and the socket 13 are arranged in consideration of the positional relationship with the reflector 16 so as to obtain optimal emission characteristics. There is also a problem that a slight shift may occur between them, which may adversely affect the light emission characteristics.

In view of the above, the present invention has been made in view of the above problems, and the housing body and the filter holder frame are integrally molded to facilitate the manufacturing process and reduce the number of manufacturing processes. It is an object of the present invention to provide a horizont light capable of reducing costs.

Another object of the present invention is to provide a horizont light which can be assembled accurately so as to obtain optimum light emission characteristics without adversely affecting light emission characteristics by employing an integrally molded structure.

And a filter holder frame formed in a frame shape.

According to the first and second aspects of the present invention, since the housing and the filter holder frame are integrally formed,
The number of parts is small and the assembling work is easy, and the number of manufacturing steps is reduced and the manufacturing steps are simplified, so that the manufacturing cost can be significantly reduced. In addition, since the reflection plate is designed to be mounted on the integrally molded housing, when mounted, the positional relationship between the housing socket and the reflection plate will satisfy the accuracy based on the dimensions at the time of design, That is, it is possible to obtain the optimum light emitting performance without causing the displacement between the lamp 12 and the reflecting plate 15.

It is possible to obtain optimal lighting performance.

[0026]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a structural perspective view showing an embodiment of a horizont light according to the present invention. In the horizon light shown in FIG. 1, the same components as those of the conventional device shown in FIG. 4 are denoted by the same reference numerals.

As shown in FIG. 1, the horizont light 20 of the present embodiment is integrally molded by subjecting a single metal plate to a manufacturing process such as bending or cutting. ing. In other words, by molding the conventional housing body and the filter holder frame integrally,
This is the Horizont light 20 of the present embodiment.

As a specific configuration, the horizon light 2
Reference numeral 0 denotes a substantially hexagonal trapezoidal housing 21 formed of a metal plate and having an opening for transmitting illumination light, as shown in FIG. A structure in which a plate is extended and formed in a frame shape, and a filter holder frame portion 22 formed so as to provide an opening for accommodating the filter holder 16 to which the color filter 16 is attached is integrally molded. It has become.

A lamp (for example, a halogen lamp) 12 as an illumination light source is provided in the housing 21, and a pair of sockets 13 for mounting the lamp 12 are provided on both sides of the housing 21. ing.

A plurality of through holes 21b are formed on the upper surface of the main body of the housing 21, and a plurality of slits 21a having a function as an exhaust port are formed on the upper and lower surfaces on the back side. . In other words, the plurality of through holes 21b or the plurality of slits 21a (not shown) provided on the upper surface on the rear side discharge the gas whose temperature rises due to the heat generated by the light emission of the lamp 12 to the outside. The lamp 12 as the illumination light source is cooled by sucking outside air through the slit 21a (see the figure).

Such a through hole 21b and a slit 21
The shape of “a” is the same as that of a conventional door (exhaust port 11 shown in FIG. 4).
Instead of a special shape as in a), it is formed in a shape penetrating a mere metal plate. That is, in the present embodiment, the plurality of through-holes 21b and the slits 21a are formed by a molding operation such as easy drilling or cutting without requiring a special and complicated molding operation as in the related art. Becomes possible.

On the other hand, as shown in the drawing, the filter holder frame 22 formed on the front surface of the
The filter holder 16 is provided with a storage portion and an opening for storing the filter holder 16 to which the various color filters 17 of B are mounted in the frame.

On the front side of both side surfaces of the filter holder frame 22, locking portions 22a for locking the housing state of the filter holder 16 when the filter holder 16 is housed as shown in the drawing. Are formed. This locking part 2
Reference numeral 2a extends from the side surface of the filter holder frame 22, and is formed by bending or cutting both side surfaces of the filter holder frame 22 as a metal plate by an easy molding operation. By forming such a locking portion 22a, the filter holder 1 accommodated in the frame is formed.
6 are locked by the locking portions 22a, it is possible to prevent the filter 6 from dropping from the filter holder frame portion 22.

Guide portions 22c for guiding the filter holder 16 into the frame while being in contact with the filter holder 16 when the filter holder 16 is accommodated are provided on the inner surfaces on both side surfaces of the filter holder frame portion 22. I have. These guides 22
c is formed so as to protrude inward in the frame, and is installed so as to be inclined with respect to the side surface of the filter holder frame 11.

The reason is that, for example, if the horizont light 20 shown in FIG. 1 is used as an upper horizont light, the upper horizont light may be provided in a two-stage upper / lower manner. In some cases, the upper horizont light installed at the lower end greatly affects the gas heated by the light emission of the upper horizont light at the lower end, and greatly affects the worst light emission performance. In addition, there is an inconvenience that the work of housing the filter holder 16 becomes difficult. Therefore, in order to solve such a problem, the lower upper horizont light is fixed to a baton or the like in a shifted state so that it is arranged before the upper horizont light.
Even in the case of such a two-stage arrangement system, the guide portion 22c is formed obliquely in order to easily accommodate the filter holder 16 in the filter holder frame portion 22. Also,
As shown in FIG. 2, by providing a through hole 22d for inserting the filter holder in the bottom surface of the filter holder frame 22, the filter holder 16 can be accommodated from either the upper or lower direction. Thereby, especially when applied to a two-stage type upper horizont light, the light emission performance is not adversely affected, and the filter holder 16 is not affected.
The work when accommodating is facilitated.

The positional relationship between the lamp 12 and the reflector 15 is one of the factors that greatly affect the light emission performance.
In the horizont light 20 of the present embodiment, this point is also improved. That is, in the present embodiment, even when the horizont light 20 is assembled, the positional relationship between the lamp 12 and the reflection plate 15 does not deviate, and the horizont light 20 can be assembled with high accuracy. Is obtained.

More specifically, as described above, a pair of sockets 13 are provided in the housing 21 with high precision, and the reflecting plate 15 is formed after the housing 21 is integrally molded. 21 at a predetermined position. That is, as shown in FIG. 4, the reflection plate is not mounted in the housing body 11 after the reflection plate is mounted on the filter holder frame 14, but simply placed in the integrally molded housing 21.
You only need to attach Therefore, the positional relationship between the socket 13 and the reflecting plate 15 in the housing 21 satisfies the accuracy based on the dimensions at the time of design.
It is possible to assemble the horizont light 20 having the optimum light emitting performance without causing a shift between the reflector 2 and the reflector 15.

Further, in the present embodiment, when the horizont light 20 shown in FIG. 1 is applied as an upper horizont light, the lamp as the illumination light source is efficiently cooled and the leakage which does not affect other objects is performed. Improvements have been made that do not produce light. Such an improved example will be described with reference to FIG.

FIG. 2 is a sectional view of the above-mentioned horizont light 20.

Normally, the upper horizont light takes in outside air into the housing incorporating the illumination light source and heats the housing heated by the illumination light source, as described above, in order to maintain stable operation of the illumination light source and to secure a service life. Although the gas inside the body is exhausted to the outside and the temperature of the gas inside the housing is always kept constant, depending on the arrangement of an exhaust port for taking in outside air or exhausting outside air, the gas from the illumination light source may be directly transmitted from the exhaust port. The light or the reflected light from the color filter 17 is projected as leakage light, and an object not requiring illumination may be projected.
For this reason, there is no particular problem with respect to the leakage light projected on the ceiling surface, but the leakage light in the downward direction illuminates another subject, which is an obstacle to the lighting setting of a stage, a studio, or the like. Further, when the cooling efficiency of the illumination light source 12 (lamp) disposed in the housing 21 is deteriorated, the gas temperature in the housing 21 is also increased. Then, the color filter 17
There is a possibility that the color may be discolored, which may adversely affect the lighting performance.

Therefore, in this embodiment, in order to eliminate such inconvenience, as shown in FIG. 2, a light shielding plate for shielding leakage light from the lower end surface of the filter holder frame portion 22 of the horizont light 20 is provided. An L-shaped member 23 and intake slits 24a and 24b are provided.

The intake slits 24a, 24b are provided for further taking in outside air for cooling the temperature inside the housing, and are provided with an intake slit 21a (see FIG. 1) on the rear side of the housing. By using them together, the outside air circulation inside the housing 21 can be improved, and as a result, the heat generation of the lamp 12 can be kept constant, and the operation stability can be maintained and the service life can be ensured. In addition, by improving the cooling efficiency, it is possible to prevent the color filter 16 from being discolored and the like, and the lighting performance is not degraded even when used for a long time.

The L-shaped member 23 is detachably provided on the lower end surface of the filter holder frame portion 22. The surface of the L-shaped member 23 is a coating material having a low reflectance and a good light absorption, such as a black gloss. Applying erased paint or having light absorption color,
The use of the material formed with the ancestral surface makes it possible to reliably block light leaked from the exhaust slits 24a and 24b.

Therefore, by providing the L-shaped member 23 and the intake slits 24a and 24b, it is possible to cool the illumination light source more efficiently than before, and to provide leakage light to other objects. Therefore, optimum illumination performance can be obtained, and furthermore, the color filter can be discolored and the service life of the color filter can be ensured by the efficient cooling.

Incidentally, in the upper horizont light 20 shown in FIG.
And a hook 26 for fixing to the baton, so that it is fixed to a light hanging baton hanging from the ceiling and arranged at a predetermined position. Although not shown, a connection cable connected to the lamp 12 protrudes from the rear surface of the housing 21, and the lamp 1 from the dimming room (not shown) is connected via the connection cable.
The light emission of the lamp 12 is controlled by supplying a dimming control signal for controlling the light emission of the lamp 2.

Next, a method of assembling the horizont light will be described. In this embodiment, since the casing 21 and the filter holder frame 22 are integrally molded, the casing as a molded product is formed. The reflector 15 is attached to the body 21, and then the lamp 12 is connected to the socket 13 in the housing 21.
The horizont light 20 can be assembled simply by attaching it to the horizont light 20.

After that, the assembled horizont light 20 is installed at a position corresponding to the purpose, and the filter holder 17 to which the color filter 17 of the corresponding color is attached is housed in the opening of the filter holder frame 14. The filter holder 17 may be stored in advance.

The horizont light 2 thus installed is
In the case of 0, at the time of illumination, the light emitted from the lamp 12 is reflected by the reflection plate 15 and then passes through the opening of the housing body 21 on the surface of the color filter 17 to pass through the horizont surface (see FIG. 3). Irradiation will serve as a horizont light.

Therefore, according to the present embodiment, since the casing and the filter holder frame are integrally formed as described above, the number of parts can be reduced and the assembling work can be easily performed. In addition, since the molding operation of the exhaust port and the like is easy, as a result, the manufacturing process can be simplified and the manufacturing cost can be significantly reduced. Further, since a structure for improving the outside air circulation action in the housing such as an L-shaped member and an exhaust slit is adopted,
The illumination light source can be reliably cooled, and the color filters can be prevented from being discolored. This allows
In addition to obtaining high-performance light-emitting characteristics, it is expensive to ensure the useful life of the lighting device.

In this embodiment, the integrated structure of the horizont light which can be used commonly for the upper horizont light and the lower horizont light has been described. However, the present invention is not limited to this.
The present invention can be applied to any lighting fixture that illuminates using an illumination light source, a reflector, and a color filter, and similar effects can be obtained.

[0052]

According to the first and second aspects of the present invention,
Since the housing and the filter holder frame are integrally molded, the number of parts is small and the assembling work is easy, and the manufacturing cost can be significantly reduced by reducing the number of manufacturing steps and simplifying the manufacturing steps. Become. In addition, since the reflection plate is designed to be mounted on the integrally molded housing, when mounted, the positional relationship between the housing socket and the reflection plate will satisfy the accuracy based on the dimensions at the time of design, That is,
According to the third aspect of the present invention, it is possible to obtain an optimum light emitting performance without causing a displacement between the lamp 12 and the reflecting plate 15, similar to the first and second aspects of the present invention. In addition to the effects, the exhaust port, the intake port, and the intake port slit can be formed by a simple molding operation, so that the manufacturing process can be further simplified, which greatly contributes to a reduction in manufacturing cost. In addition, by providing the exhaust port, the intake port, and the intake port slit, the external air circulation action in the housing is activated, so that the illumination light source can be efficiently cooled. Therefore, not only can the operation stability of the illumination light source be maintained and the service life can be ensured, but also the gas in the housing can be efficiently cooled, preventing the color filter from discoloring due to the heated gas. It is possible to obtain optimal lighting performance.
