Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting device suitable for use on the ceiling of a hotel banquet hall or the like.

[Conventional technology]

BACKGROUND ART Conventionally, highly decorative lighting fixtures such as chandeliers have often been used as lighting fixtures placed on the ceiling in hotel banquet halls and the like.

By the way, year by year, hotel banquet halls are being used not only as banquet halls, but also for a wider range of purposes, such as conference halls, various ceremonies, and new product presentation halls. For this reason, it has become desirable for lighting equipment to not only be highly decorative, but also to have the ability to change the atmosphere of a venue through colored lighting.

However, when using colored lighting, it is difficult to harmonize the level of coloring used to create an atmosphere with the level of brightness to be ensured within the venue.

For example, if you place an appropriate number of colored lamps that emit light of a predetermined color toward the ceiling of a venue, and use these lamps to color the ceiling to create a predetermined atmosphere, the coloring will not be satisfactory. However, a situation may arise in which the desired brightness within the venue cannot be satisfied.

Therefore, in order to increase the brightness in the venue, dedicated lamps have been provided in addition to the coloring lamps. However, if another lamp is provided in this way, there is a risk that the light from this lamp will affect the coloring, making it impossible to achieve clear coloring, and the configuration will result in a mix of different types of lamps being arranged. Therefore, there is a risk that the construction work will become troublesome.

[Purpose of the invention]

This invention was made in view of the above circumstances,
It is possible to apply a clear color to the ceiling, provide the desired brightness in the room without affecting the color, and the fixture itself is highly decorative, providing sufficient lighting effects for a wide range of uses. The purpose is to obtain lighting equipment that can

In the figure, A is the ceiling body, and this ceiling body A has a structure in which a number of hexagonal concave surfaces B are connected in succession in a honeycomb shape when viewed from above, and each concave surface B has three diamond-shaped concave surfaces B. The plate-like structure 1 has a concave surface B
They are arranged 120 degrees apart from each other around the center of the center. The plate-like structure 1 is made of plasterboard, for example, and its surface is white so that it can reflect light of all colors, and has a rough surface so that it can reflect light diffusely. .

On the other hand, 3 is a lighting fixture according to the present invention, which is arranged corresponding to each of the concave surfaces B. This lighting fixture 3 is disposed below the center of the concave surface B and is supported by three pipes 5. Further, the base end side of the pipe 5 is attached to a tube body 6 disposed on the downward protrusion 4 of the ceiling main body A (see FIGS. 6 to 8). In addition, pipe 5
An electric wire for supplying electricity to the lighting fixture 3 is inserted through. The lighting equipment 3 is shown in Figures 3 to 5.
As shown in the figure, a frame body 7 hanging from the ceiling,
A lighting device comprising a main lamp 12 held at the center of the lower part of the frame body 7 to directly illuminate the room, and a plurality of decorative glass bodies 10 arranged in a ring around the frame body. The frame body 7 includes a reflecting plate part 11 that forms a downwardly facing depression for arranging the main lamp 12 and reflects the light emitted from the main lamp 12 downward; It includes a cylindrical outer wall portion 8 extending upwardly from the lower periphery while expanding in diameter, and a partition plate 13 that partitions the interior of the outer wall portion 8 into upper and lower parts to form a lamp accommodating portion 16 that is open upward. , a plurality of coloring lamps 1 for coloring the ceiling are installed in the lamp accommodating portion 16.
4, 15A, 15B, and 15C are provided below the upper edge of the outer wall portion 8, and further, the outer wall portion 8
A plurality of auxiliary lamps 9 for illuminating the glass body 10 are arranged at appropriate intervals at a position near the bottom of the glass body 10, and the light from the auxiliary lamps is reflected by the stepped portion 8a of the outer wall portion 8 and the outer circumferential surface 8b. It is configured so that it is reflected downward.

A plurality of the above-mentioned step portions 8a are provided so that the outer wall portion 8 has a step-like cross section, and each has the effect of reflecting light downward.

The partition plate 13 is formed by bending the periphery of a disc-shaped plate upward, and each coloring lamp 1
It also functions as a reflector that reflects the lights of 4, 15A, 15B, and 15C upward.

Coloring lamps 1 arranged on this partition plate 13

15C is arranged, the lamp 15A is red,
The lamp 15B emits blue light, and the lamp 15C emits green light, which are the three primary colors of light.

These lamps 14, 15A, 15B, 15C
The amount of light of each lamp is adjusted in relation to each other by a control device using a computer, so that one concave surface B of the ceiling body A facing the lamp can be illuminated with arbitrary color and illuminance. It is something. Further, each lighting fixture 3 is individually controlled by the white lamp 1 by the control device.
4 and colored lamps 15A, 15B, and 15C. The reason why the white lamp 14 is provided is that white light can theoretically be obtained by simply superimposing the three primary colors of light, but in reality, due to current fluctuations, manufacturing errors between lamps, etc. This is because it is difficult to obtain white light just by overlapping them.

The pipe body 6 is supported by the building frame via a support member (not shown) such as a hanging bolt,
In addition to the function of supporting the lighting fixture 3, it also has the function of supporting various equipment. That is, in FIG. 2, ◎ represents the lighting fixture 3, ○ represents the air conditioning outlet or inlet 21, sprinkler 22, and smoke detector 23. These devices are shown in FIGS. 6 to 8. As shown, it is attached to the tube body 6 using attachment members such as bolts, and is arranged in a well-balanced manner at a predetermined position on the ceiling surface. Further, 24 in FIG. 2 is a suspension body on which the name of the ceremony, etc. is drawn, and this suspension body 24 is suspended by a rope passing through the tube body 6.

With this configuration, the light emitted from the main lamp 12 and the sub lamp 9 is emitted only downward by the reflection plate part 11 and the stepped part 8a and outer peripheral surface 8b of the outer wall part 8, respectively. Become.

On the other hand, coloring lamps 14, 15A, 15B, 1
The irradiation range of the light emitted from 5C is narrowed to a predetermined range on the ceiling A side by the partition plate 13 and the upper edge of the outer wall part 8. Therefore, the light from the main lamp 12 and the light from the auxiliary lamp 9 are transmitted to the coloring lamps 14, 15A, 15B,
The effect of 15C on the coloring is negligible, and by using lamps installed for each purpose, the ceiling can be clearly colored, and the brightness in the venue can be adjusted to the optimal state.

Next, the coloring lamps 14, 15A, 15B, 1
The coloring of the ceiling using 5C will be explained.

(i) When illuminating the entire ceiling in white, the control device lights up the partition plate 1 for all lighting fixtures 3.
Among the lamps arranged above 3, white lamp 14
While energizing only the colored lamps 15, the other colored lamps 15
An operation is performed to stop the power supply to A, 15B, and 15C. As a result, all of the concave surfaces B can be illuminated in white, and by extension, the entire ceiling can be illuminated in white.

(ii) When illuminating the entire ceiling with any one of the three primary colors of red, blue, and green, the control device energizes only the colored lamps of the desired hue for all lighting fixtures 3, and also energizes the other colored lamps. perform an operation to stop energization. Thereby, all of the concave surfaces B can be illuminated with any one of the three primary colors.

(iii) When illuminating the entire ceiling with an arbitrary neutral color different from the three primary colors, each lighting fixture 3
For all, each colored lamp 15A, 15
The adjustment operation of the current supplied to B and 15C is similarly performed. As a result, each colored lamp 15
The light amounts of A, 15B, and 15C are adjusted, and the light emitted from each colored lamp 15A, 15B, and 15C is superimposed on each other and irradiated onto the concave surface B.
All of the concave surfaces B can be illuminated with the same arbitrary neutral color.

(iv) When each of the concave curves B arranged in a honeycomb shape is individually illuminated in a desired color to draw a single image on the entire ceiling, the control device controls the white lamp 14 and each Adjustment of the current supplied to the colored lamps 15A, 15B, and 15C is performed individually. As a result, for each lighting fixture 3, the white lamp 14 and each colored lamp 15A, 15B, 1
The amount of light of 5C is adjusted, and each concave surface B can be illuminated with any color and illuminance, thereby making it possible to draw one image on the entire ceiling (see FIG. 9).

(v) When changing a ceiling surface that is illuminated in one color (for example, red) to another color (for example, blue),
Alternatively, when changing the ceiling surface in the states (i) to (iv) above to another state, or furthermore, when changing the ceiling surface on which one image is drawn so that it is drawn on another image, The current to the white lamp 14 and the colored lamps 15A, 15B, and 15C may be changed instantaneously to switch the ceiling surface to another state, or the current may be gradually changed to change the color of the ceiling surface. You can also actively take advantage of the process of change.

In addition, in this embodiment, equipment such as air conditioning outlets, suction ports 21, sprinklers 22, smoke detectors 23, etc. are arranged on the protrusion 4 of the ceiling body A, which is the boundary between each concave surface B. Since the shadow of the equipment is prevented from appearing on the concave surface B, this is particularly preferable in terms of appearance.

In the above embodiment, the concave surface B has a hexagonal shape in a plan view, but the shape of the concave surface B is not limited to this, and may be, for example, a triangular shape in a plan view or any other arbitrary shape. .

Further, in the above embodiment, an example in which the present invention is applied to the ceiling of a hotel banquet hall is described, but the present invention is not limited to this, and can be applied to the ceiling of other rooms such as a conference hall or an entrance hall. Of course, it can also be applied to

〔Effect of the invention〕

In the lighting fixture of the present invention, in order to maintain brightness, the light emitted from the main lamp that directly illuminates the room and the auxiliary lamp that illuminates the decorative glass body is reflected by the reflector part of the frame body and the outer wall part, respectively. It will be emitted only downward.

On the other hand, the irradiation range of the light emitted from the coloring lamp is narrowed to a predetermined range on the ceiling side by the partition plate provided within the frame and the upper edge of the outer wall. Therefore, the light from the main lamps and the light from the auxiliary lamps has only a slight effect on the coloring by the coloring lamps, and the ceiling is clearly colored by lamps installed for each purpose, and the venue The brightness inside can also be adjusted to the optimum state. In addition, the glass body placed outside the sub-lamp has a decorative function as well as a function of preventing the light from the sub-lamp from directly entering people's eyes. At this time, since the glass body is transparent or semi-transparent, you can see the ceiling surface illuminated by the colored lamps through the glass body.
There is no problem in which the glass body becomes an obstacle to viewing the ceiling surface, which can be colored in various ways.

In addition, the light from the secondary lamp is reflected by the outer wall, which has multiple steps extending in the circumferential direction of the frame, and efficiently illuminates the decorative glass body while changing the illuminance in multiple stages in the height direction. , the fixture itself is highly decorative, and can now provide sufficient lighting effects for a wider range of uses.
