Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a border light or a horizont light, which is a lighting device for production used at altars, funeral halls, various banquet halls, stages of multipurpose halls and the like at funeral halls.

[0002]

2. Description of the Related Art Border lights and horizont lights have conventionally been used as lighting devices for stage performances.
Here, the border light 20 is a lighting device that is suspended from the baton 1 at the upper part of the stage as shown in FIG. 4 and uniformly illuminates the entire stage, and the horizont light 30 is a horizont that is the background of the stage. An illumination device for illuminating the curtain 40; an upper horizont light 30a suspended from the baton 1 and illuminating the horizont curtain 40 from above the stage; and a horizont curtain 40 installed on the floor of the stage
There are two types of lower horizont lights 30b that illuminate the light.

[0003] The conventional border light 20 and the horizont light 30 are each provided with a socket in a light cover divided into a plurality of sections, covered with a reflector, and an incandescent lamp or a halogen lamp is attached to the socket. Is a lighting device having an integrated structure of light sources. In general, light from a light source passes through a filter to become light of three primary colors of red, green, and blue, and is combined with these three primary colors to produce and produce various colors.

[0004]

However, in the conventional illumination using a light source, the temperature of a portion to be illuminated and the temperature around the stage increase due to the heat radiated by the irradiation light. Therefore, when it is desired to maintain the flowering state of the flowers displayed around the stage or the altar and to reuse the flower many times, the flowering state progresses rapidly and does not last long. Further, since the color temperature of the light beam is low, when white light is applied to a white object such as a curtain, the light may appear colored and yellowish. Furthermore, incandescent lamps and halogen lamps have a long life of about 1000 hours even if they are long,
Replacing border lights and horizont lights installed at high places for stage lighting was a time-consuming task.

SUMMARY OF THE INVENTION In view of the above problems, the present invention is to solve the following problems by using a fluorescent lamp. 1. The temperature rise due to irradiation light is reduced to reduce the influence on the flowers and the like that are displayed on the stage and altars. 2. The necessary range of illumination is provided by adjusting the illumination range. 3. Raise the color temperature of the illumination light to make it closer to natural light and improve the color tone by illumination. 4. Extend the lamp replacement maintenance cycle and reduce costs.

[0016]

As described above, the present invention relates to a border light that illuminates the stage, altar and the like evenly from above.
The outline of the border light is a border light using a fluorescent lamp, which is characterized by having a fluorescent lamp and a reflection plate or a light shielding plate. Therefore, it is possible to prevent an increase in the temperature of the border light irradiation surface. An experiment supporting this has been performed, and will be described with reference to FIG. FIG. 5 is a diagram showing the relationship between the distance from the light source and the irradiation surface temperature. It can be seen that when a conventional incandescent lamp is used, the irradiation surface temperature sharply increases as approaching the light source. On the other hand, when a fluorescent lamp is used, it can be seen that the irradiation surface temperature is maintained at substantially the room temperature level even when approaching the light source. In addition, the diffusion of the illumination light of the fluorescent lamp can be adjusted by providing a reflection plate or a light shielding plate. Further, the life of a conventional incandescent lamp or a halogen lamp is about 1000 hours, whereas the life of a fluorescent lamp is 12000 hours, which is 10 times or more.
The lamp replacement cycle can be lengthened, and the cost can be reduced. And the color temperature of the fluorescent lamp is 400
Since it is at a level of 0 ° K to 5000 ° K, which is closer to sunlight than the color temperature of 2700 ° K to 3200 ° K of incandescent lamps and halogen lamps, it is possible to improve the color tone by illumination.

Further, the border light may include a plurality of the fluorescent lamps, and may have an angle adjusting plate capable of changing an arrangement of the plurality of fluorescent lamps. Therefore, in the conventional border light, incandescent lamps or halogen lamps as point light sources are used in a line, and the spread range of the illuminating light is determined and fixed by the installation height of the appliance and the mounting direction of the entire appliance, whereas Therefore, the present invention can adjust the attachment angle of the fluorescent lamp individually according to the required illumination range with respect to the installation height of the fixture, so that the spread range of the illumination light can be adjusted. The degree of freedom in installation and lighting effects can be increased.

FIG. 6 shows that the border light according to the present invention has the same height as that of a conventional border light suspended at 4 m above the stage, where incandescent lamps (six 100 W) are used. The illuminance distribution when the lamps (five 40W) are used is shown, and it can be seen that the illuminance distribution is substantially the same as the border light using the conventional incandescent lamp. This is the reason why fluorescent lamps have not been used as border lights in the past.Fluorescent lamps support that the present invention sufficiently covers the drawback that illumination light is diffused. It also shows the effect that the power consumption can be suppressed to half or less with the illuminance distribution.

Further, the present invention provides a horizont light for illuminating a curtain at the back of a stage from an upper portion of a stage, an altar, or the like.
The horizont light has a gist of a horizont light using a fluorescent lamp, which is characterized by having a fluorescent lamp and a reflection plate or a light shielding plate, wherein the horizont light is provided with a plurality of the fluorescent lamps, Since the configuration may include an angle adjusting plate capable of changing the arrangement of the plurality of fluorescent lamps, the same effect as the border light can be obtained in the horizont light.

Further, the present invention provides a horizont light for illuminating a curtain at the back of a stage from a lower part of a stage, an altar or the like, wherein the horizont light has a fluorescent lamp. Therefore, the above advantages of the fluorescent lamp can be used in the lower horizont light.
