Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminaire used to illuminate a room, and more particularly to a luminaire provided with a portion whose color changes when a lamp is turned on or off.

[0002]

2. Description of the Related Art In a general lighting apparatus, a reflecting surface for reflecting light of a lamp, a baffle portion, and the like are merely coated with a single color such as white using ordinary paint. Therefore, there is a problem that lighting equipment with baffle part can not cut glare when lighting it by painting the baffle part white, and mood lighting equipment does not change color even when lighting and the effect of mood lighting is There is a problem of being low.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to change a color when a lamp is turned off and a color when the lamp is turned on to obtain a desired lighting effect. In order to provide a lighting fixture that can obtain

[0004]

To achieve the above object, the luminaire of the present invention is characterized in that a color change coating portion 1 of temperature-indicating paint that changes its color due to temperature change is provided in a portion where the lamp 2 is exposed to light. And

[0005]

When the lamp 2 is turned on, the heat of the lamp 2 changes the color of the color-changing paint portion 1 of the temperature-indicating paint, and the desired lighting effect can be obtained by changing the color when the lamp is turned off and when it is turned on.

[0006]

EXAMPLE First, the example shown in FIG. 1 will be described. The luminaire main body 3 is formed in a bottomed cylindrical shape whose lower surface is opened and whose upper surface is closed. In the lighting fixture body 3, the lamp 2 and the reflection plate 6 are provided. Reference numeral 8 is a socket, and 9 is a frame mounting spring. A baffle portion 7 is provided below the reflection plate 6, and the discoloration coating portion 1 made of temperature-indicating paint is provided on the inner surface of the baffle portion 7.
Is provided. It is preferable to use a reversible thermo paint as the temperature-indicating paint forming the discolored coating portion 1, but a quasi-reversible thermo paint may be used. In the case of the present embodiment, the discoloration coating part 1 uses a temperature-indicating paint which is white at room temperature and changes color to black when the temperature rises. Then, when the lamp 2 is turned off, the baffle portion 7 is white, and when the lamp 2 is turned on, the temperature rises and the color changes to black. As a result, the baffle portion 7 is white when it is turned off and matches the color of the ceiling 5 so that it blends into the space inconspicuously, and when it is turned on, the baffle portion 7 is black and cuts glare.

Next, the embodiment shown in FIG. 2 will be described.
In the case of the present embodiment, the discoloring coating portion 1 made of temperature-indicating paint is provided on the inner surface of the reflecting plate 6. A milky white cover 10 is attached to an opening on the lower surface of the lighting fixture body 3. Further, in the case of the present embodiment, the discoloration coating section 1 uses a temperature indicating paint which is red at room temperature and changes color to blue when the temperature rises. Therefore, the reflector plate 6 is red when turned off and blue when turned on. Therefore, since the milky white cover 10 is visible when it is turned off, it blends into the space inconspicuously. Further, when the lamp is turned on, red light is first reflected by the reflecting plate 6 so that red light is visible, and as the time passes, the discoloration coating portion 1 of the reflecting plate 6 turns blue and blue light is seen. For this reason, it is possible to create a mood and create an image of the sunset as the sun sets and the night goes on.

Next, the embodiment shown in FIG. 3 will be described. In the case of this embodiment, the main lamp 2a and the auxiliary lamp 2b are installed as the lamp 2. A decorative frame 11 is attached to the lower surface of the luminaire main body 3. A shade 12 is attached around the main lamp 2a so that the light of the main lamp 2a can make the decorative frame 1
Irradiation is performed from the opening 13 at the center of 1.
The light of the auxiliary lamp 2b is applied to the upper surface of the decorative frame 11. The upper surface of the decorative frame 11 is coated with the discoloration coating portion 1 of the temperature-indicating paint, and the lower surface of the decorative frame 11 is painted white. In this embodiment, the discoloration coating section 1 uses a temperature-indicating paint which is red at room temperature and changes to blue when the temperature rises. However, when the light is turned off, the white color of the lower surface of the decorative frame 11 is visible, so that it blends into the space inconspicuously. When the light is turned on, red light is first reflected on the upper surface of the decorative frame 11, so that red light is visible. The discolored coating portion 1 on the upper surface of the sheet turns blue and blue light can be seen. For this reason, it is possible to create a mood and create an image of the sunset as the sun sets and the night goes on. At this time, the discoloring coating portion 1 of the temperature-indicating paint may be provided on the inner surface of the shade 12.

Next, the embodiment shown in FIG. 4 will be described. A lighting device is attached to the wall surface 13, the outer surface of the shade 12 is painted white, and the inner surface of the shade 12 is painted with the discoloration coating portion 1. This discoloration coating part 1 is also red at room temperature,
A thermochromic paint that turns blue when the temperature rises is used. However, when the light is turned off, the white color of the outer surface of the shade 12 is visible, so that it blends into the space inconspicuously. When the light is turned on, red light is first reflected on the inner surface of the shade 12, so that red light is visible. The discoloration coating part 1 turns blue and blue light can be seen. For this reason, it is possible to create a mood and create an image of the setting sun setting and the night going on.

It is preferable to use a temperature-indicating paint that changes from red to blue when representing an image of the setting sun, but a color-indicating paint that changes from green to blue is used when representing an image of deep dive into the sea. It is preferable.
Further, the color change of the temperature-indicating paint is not limited to the change of two colors, but the color change of three or more colors is used during the temperature change (for example, red →
It is also preferable that (orange → blue → green).

[0011]

As described above, according to the present invention, the color change coating portion of the temperature-indicating paint whose color changes depending on the temperature change is provided in the portion where the light of the lamp is exposed. And a desired color can be obtained when the light is turned off and when the light is turned on, and an excellent lighting effect can be obtained.
