Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lighting device for a production space such as a spotlight or a floodlight used in a production space such as a theater stage or a TV studio, and an improvement of a color filter used in the lighting device.
[0002]
[Prior art]
Conventionally, as a color filter used in this type of illumination device, a color filter obtained by applying a desired color to a film made of a synthetic resin such as polyester, polycarbonate, or polyethylene terephthalate is exchangeably held by a filter holder. 2. Description of the Related Art There is known a lamp used by being detachably attached to a front opening of a lamp body.
[0003]
However, the colored filter made of the synthetic resin film as described above may be melted because it directly receives the energy emitted from the light source, and particularly in a lighting device using a high-output light source or used continuously for a long time. There was a problem that such a phenomenon became remarkable.
[0004]
In order to solve such a problem, for example, Patent Document 1 describes that a synthetic resin material contains a flame retardant material to form a colored filter. When used in spotlights or floodlights that are used continuously for a long time, it is hard to say that the risk of melting is eliminated, and further improvements have been desired.

[Problems to be solved by the invention]
In order to solve the above problems, the applicant of the present application uses a dichroic-coated reflector to transmit heat rays and reflect only visible rays forward of the light emitted from the light source, so that the colored filter receives high heat. As a result of conducting research on the assumption that the influence can be reduced, it was found that melting of the colored filter could not be prevented only by removing heat rays.
[0007]
The present applicant further considers that the light energy contained in visible light greatly affects the burning of the color filter, the color filter color such as a cool color such as blue and green, the warm color such as red and orange, and the spectrum of a light bulb. From the intensity distribution, it was found that the wavelength range in which the energy absorbed by the coloring filter affects each color tone is different, and that the energy contained in visible light is particularly large in a dark color tone.
[0008]
On the other hand, when an attempt is made to reproduce a desired color tone using only an interference filter that does not cause energy absorption, color unevenness occurs on an irradiation surface due to a difference in optical path length between a central portion and a peripheral portion of the interference filter. There is a problem that a desired color tone cannot be obtained.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the conventional circumstances as described above, and its purpose is to reduce the energy absorbed by a colored filter in a lighting device that uses a high-output light source or is used continuously for a long time. It is an object of the present invention to provide a novel color filter which can reduce the color filter to prevent the melting of the colored filter and obtain a desired color without causing color unevenness on an irradiation surface, and a lighting device equipped with the color filter.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the first invention of the present application is a color filter for a lighting device for effect space, comprising a color filter made of a synthetic resin having a desired color, and a filter holder for holding the color filter interchangeably. So,
An interference filter for selectively transmitting visible light having a predetermined wavelength is attached to the light source side surface of the filter holder,
The interference filter is formed so as to transmit only visible light having a wavelength of a color component to be enhanced by the coloring filter and reflect visible light having other wavelengths.
[0011]
According to such a configuration, of the visible light emitted from the light source, only the wavelength of the color component to be emphasized by the color filter passes through the color filter, and the visible light of other wavelengths is reflected by the interference filter and removed. Is done. Therefore, since the light passing through the color filter is selected only for the wavelength of the color component to be emphasized by the color filter, the energy absorbed by the color filter is greatly reduced, and the light source has a high output or a long time. Even in the case of continuous use, it is possible to prevent the coloring filter from melting, and to obtain a desired color by the coloring filter.
Further, since the color filter and the interference filter are one set, it is not necessary to select the interference filter for each color of the color filter, and the handling when the color filter is used becomes easy.
Furthermore, since the coloring filter is held by the filter holder so as to be exchangeable, when the coloring filter is deteriorated due to long-term use, it is possible to use the interference filter as it is and replace only the coloring filter.
[0012]
The second invention of the present application is a color filter for effect space formed by laminating an interference filter that selectively transmits visible light of a predetermined wavelength on a light source side surface of a synthetic resin colored filter having a desired color. hand,

According to such a configuration, as in the first invention, of the visible light emitted from the light source, only the wavelength of the color component to be emphasized by the coloring filter passes through the coloring filter, and the visible light of the other wavelengths Are reflected and removed by the interference filter. Therefore, since the light passing through the color filter is selected only for the wavelength of the color component to be emphasized by the color filter, the energy absorbed by the color filter is greatly reduced, and the light source has a high output or a long time. Even in the case of continuous use, it is possible to prevent the coloring filter from melting, and to obtain a desired color by the coloring filter.
Further, since the color filter and the interference filter are one set, it is not necessary to select the interference filter for each color of the color filter, and the handling when the color filter is used becomes easy.
[0014]
In the third invention of the present application, in the first invention or the second invention, the coloring filter is colored in a cool color such as blue or green, and the short wavelength side of the interference filter has a transmission characteristic and a long wavelength. The side is formed as a reflection characteristic such that the boundary between transmission and reflection of visible light is within the range of 550 to 720 nm.
[0015]
According to such a configuration, only the wavelength of the color component to be emphasized by the cool color filter passes through the color filter, and visible light of other wavelengths is reflected and removed by the interference filter. That is, since the light passing through the coloring filter is selected only for the wavelength of the color component to be emphasized by the coloring filter, the energy absorbed by the cold tone coloring filter is greatly reduced, and Even when the filter is used continuously for a long time, it is possible to prevent the melting of the color filter having a cool color tone and to obtain a desired cold color tone.
[0016]
According to a fourth aspect of the present invention, in the case where the coloring filter is colored in a cool color such as blue, green, or the like, the interference filter reflects a wavelength including visible light exceeding 600 nm and emits a visible light having a wavelength of 600 nm or less. It is characterized in that it is formed to transmit only light rays.
[0017]
When the interference filter is formed in this way, it is possible to cope with a wide range of colored filters that are colored in a cool color such as blue and green, and it is not necessary to select an interference filter for each color. It will be easier.
[0018]
The fifth invention of the present application is the invention according to the first invention or the second invention, wherein the coloring filter is colored in a warm tone such as red or orange, and the short wavelength side of the interference filter has a reflection characteristic and a long wavelength. The side is characterized by being formed as a transmission characteristic such that a boundary between reflection and transmission of visible light is within a range of 500 to 550 nm.
[0019]
According to such a configuration, only the wavelength of the color component to be emphasized by the warm-tone coloring filter passes through the coloring filter, and visible light of other wavelengths is reflected and removed by the interference filter. That is, since the light passing through the coloring filter is selected only for the wavelength of the color component to be emphasized by the coloring filter, the energy absorbed by the warm-tone coloring filter is greatly reduced, and the light source has a high output. Even when the color filter is used continuously for a long time, it is possible to prevent the coloring of the warm color tone filter from being melted and to obtain a desired warm color tone.
[0020]
The sixth invention of the present application is directed to a sixth aspect of the present invention, wherein when the coloring filter is colored with a warm tone such as red or orange, the interference filter reflects a wavelength including visible light of less than 520 nm and a visible wavelength of 520 nm or more. It is characterized in that it is formed to transmit only light rays.
[0021]
When the interference filter is formed in this manner, it is possible to cope with a wide range of colored filters having a warm color such as red and orange, and it is not necessary to select an interference filter for each color. It will be easier.
[0022]
The seventh invention of the present application is a lighting device for effect space, which is provided with any of the color filters of the first invention to the sixth invention interchangeably.

Therefore, the light passing through the color filter is selected to be visible light having the wavelength of the color component to be emphasized by the color filter, so that the energy absorbed by the color filter is further greatly reduced, and the light source has a high output. Even when the color filter is used continuously for a long time, it is possible to more reliably prevent the color filter from melting, and to obtain a desired color by the color filter.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an example of an embodiment of a lighting device according to the present invention will be described with reference to the drawings.
The lighting device shown in FIGS. 1 and 2 is a spotlight A used in a production space such as a theater stage or a TV studio. The spotlight A is provided in a lamp body 1 formed in a long cylindrical shape. At least the light source 2, the reflector 3, the aperture plate 4, and the lens 5 are provided at predetermined locations, and the color filter 7 is detachably mounted on a filter holding portion 6 provided at the front opening of the lamp body 1. Is emitted through the aperture 8 of the aperture plate 4, the lens 5, and the color filter 7 to irradiate light of a desired color.
[0025]
The reflector 3 disposed in the rear of the interior of the lamp body 1 performs dichroic processing on the reflection surface, transmits heat rays of the light a emitted from the light source 2, and reflects only the visible light rays b forward. It is formed as follows.
[0026]
As shown in FIGS. 3 and 4, the color filter 7 attached to the front opening of the lamp body 1 is made of a synthetic resin colored filter 10 having a desired color and before and after the colored filter 10 is sandwiched. A filter holder 11 in which the side edges of the holding plates 11a and 11b are rotatably pivotally connected to hold the colored filter 10 in an exchangeable manner, and the holding plates 11a and 11b have openings 11d, and a visible wavelength of a predetermined wavelength. It is formed from an interference filter 12 that selectively transmits the light beam c.
[0027]
The coloring filter 10 is obtained by subjecting a film made of a synthetic resin having high flame retardancy and transparency, for example, a synthetic resin such as polyester or polycarbonate, to a desired coloring, and various colors such as blue, red, orange, and yellow are provided. A plurality of applied color filters 10 are prepared in advance, and a color filter 10 of an arbitrary color is selected and used.
[0028]
The interference filter 12 alternately laminates layers having a high refractive index (for example, a layer of titanium oxide (TiO ₂ )) and layers having a low refractive index (for example, a layer of silicon oxide (SiO ₂ )), and laminates the layers. The number is arbitrarily selected, and only the visible light c having the wavelength of the color component to be emphasized by the coloring filter 10 is transmitted, and the visible light d having the other wavelength is reflected.
[0029]
The interference filter 12 is integrally attached to the light source side surface of the filter holder 11, in this example, the outer surface side of the rear holding plate 11a by bonding or the like.
[0030]
According to the spotlight A of this example having such a configuration, of the light a emitted from the light source 2, most of the heat rays pass through the reflector 3 and are removed to the rear, and only the visible light b is reflected by the reflector. 3 and transmitted forward, and among the visible light b, only the visible light c of the wavelength of the color component to be emphasized by the coloring filter 10 passes through the interference filter 12, and the visible light of other wavelengths d is reflected by the interference filter 12 and removed.
[0031]
Therefore, the visible light c ′ passing through the coloring filter 10 is selected only for the wavelength of the color component to be emphasized by the coloring filter 10, so that the energy absorbed by the coloring filter 10 is greatly reduced.
Therefore, even when the light source 2 has a high output or is used continuously for a long time, it is possible to prevent the coloring filter 10 from being melted, and to obtain light c ′ of an appropriate color developed by the coloring filter 10.
[0032]
In addition, since the interference filter 12 is attached to the filter holder 11 and the color filter 10 is held by the filter holder 11, the color filter 10 and the interference filter 12 become one set, and the interference filter 12 is selected for each color filter 10 of each color. Less need to be done. Further, when the coloring filter 10 is deteriorated due to long-term use, the interference filter 12 may be left as it is, and only the coloring filter 10 may be replaced.
[0033]
The above-described color filter 7 may be configured as shown in FIG.
That is, the color filter 7 ′ is formed by laminating the interference filter 12 on the light source side surface of the colored filter 10.
[0034]
When such a color filter 7 ′ is detachably held on the filter holding portion 6 of the spotlight A, the interference filter 12 is laminated on the colored filter 10 in addition to the effect of the spotlight A. Therefore, there is no need to select an appropriate interference filter 12 for each of the colored filters 10 that have been subjected to various colors, and there is an effect that the handling of the color filters 7 ′ in the lighting site of the presentation space is facilitated.
[0035]
As described above, the interference filter 12 selects the number of layers of the high-refractive index layers and the low-refractive index layers that are alternately laminated for each color of the coloring filter 10, and selects the color component to be emphasized by the coloring filter 10. Is formed so as to transmit only visible light c having a wavelength of, and reflect visible light d having other wavelengths. In the case of using each of the colored filters 10 to which the color numbers in the “filter sample book” are applied (blue and green colors of No. 52 to No. 87), the boundary between transmission and reflection by the interference filter 12 is 550 to 720 nm. Within the range.
Further, when the interference filter 12-1 formed so as to transmit only the visible light c having a wavelength of 600 nm or less and reflect the visible light d having a wavelength exceeding 600 nm is used, coloring of a blue-green cool tone (for example, Color filter 10), which can be used in common for each of the colored filters 10 which have been subjected to the color numbers of No. 52 to No. 87 in the “color filter sample book”, which are colored blue and green. The operation of selecting an appropriate interference filter 12 for each filter 10 becomes unnecessary, and there is an effect that the handling of the color filter 7 at the lighting site in the presentation space becomes easy.
[0036]
In addition, each of the colored filters 10 to which a warm color tone of red and orange is applied (for example, red and orange colors having color numbers of No. 22 to No. 35 in the “color filter sample book”). When used, the boundary between transmission and reflection by the interference filter 12 is in the range of 500 to 550 nm.
When the interference filter 12-2 formed to transmit only visible light c having a wavelength of 520 nm or more and reflect visible light d having a wavelength of less than 520 nm is used, a warm color tone of red or orange is used (for example, , Which can be used in common for each of the colored filters 10 that have been given a color number of No. 22-No. The operation of selecting an appropriate interference filter 12 for each filter 10 becomes unnecessary, and there is an effect that the handling of the color filter 7 at the lighting site in the presentation space becomes easy.
