Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an illuminated sign post that has a built-in temperature sensor and emits light in a comfortable color tone according to the outside temperature.

[0002]

[Prior Art]

 The conventional illuminated sign posts and gate lights have a constant color tone, and there is a problem that incandescent lamps feel hot in summer and fluorescent lamps feel cold in winter. Therefore, the applicant of the present invention has previously devised a device as shown in FIG. This includes a fluorescent lamp 3a that emits green light, a fluorescent lamp 3b that emits red light, and a fluorescent lamp 3c that emits blue light inside the illumination unit 2 of the sign post 1, and the detection of the temperature sensor 4 is performed. The fluorescent lamps 3a, 3b, 3c are turned on / off according to the temperature, and an appropriate color tone is created by the three primary colors of red, blue, and green. ing.

[0003]

[Problems to be solved by the device]

 However, in the case of the structure shown in FIG. 4, there is a problem that the color may fluctuate near the temperature of the boundary of the color tone, and the color type is produced by turning on / off the fluorescent lamps 3a, 3b, 3c. However, there is a problem that a plurality of fluorescent lamps 3a, 3b, 3c are required.

The present invention has been made in view of the above problems, and an object of the present invention is to eliminate an unnatural color change near the temperature boundary point, and to adjust the temperature according to the temperature. An object is to provide an illuminated sign post that can be illuminated with various colors and can be illuminated with a single lamp.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the illuminated sign post of the present invention accommodates a lamp 3 such as a fluorescent lamp in an illuminating part 2 of the sign post 1 and is translucent, and its color tone continuously changes in the circumferential direction. A cylindrical color panel 5 is rotatably mounted around the lamp 3, and the temperature sensor 4 for detecting the temperature and the color panel 5 is rotated according to the temperature detected by the temperature sensor 4 to adjust the color tone according to the temperature. The illumination unit 2 is provided with a control unit 6 that controls so that the above portion faces the surface side of the illumination unit 2.

[0006]

[Action]

 When the temperature sensor 4 detects the outside air temperature, the color panel 5 rotates around the lamp 3 according to the temperature, and the color tone of the color panel 5 corresponding to the temperature faces the front surface side of the lighting unit 2 and the lamp 1 The light from the light source emits light in a color tone according to the temperature. At this time, since the color tone of the color panel 5 continuously changes in the circumferential direction, it is possible to eliminate an unnatural change in color even near the temperature boundary point, and it is possible to illuminate various kinds of colors.

[0007]

【Example】

 As shown in FIG. 1, there is an entrance 8 for postal matter in the upper part of the front of the sign post 1. The inside of the sign post 1 is divided by a partition plate 9 to form a storage part 10 for the postal matter and an illuminating part 2. It is provided. A lighting cover 11 is attached to the front surface of the lighting unit 2. A lighting fixture 3 such as a fluorescent lamp is provided inside the lighting unit 2, and a cylindrical color panel 5 is rotatably mounted around the lighting fixture 3. The color panel 5 is provided by continuously changing the color tone of a cylinder formed of a translucent material. For example, as shown in FIG. 2B, the color tone is continuously changed from blue (cold color) to white (intermediate) to red (warm color). A temperature sensor 4 for detecting the outside air temperature is mounted on the front surface of the lighting unit 2, and a control unit 6 for controlling according to the temperature detected by the temperature sensor 4 is provided in the lighting unit 2. The control unit 6 has a drive device for driving the color panel 5, and the color panel 5 is rotationally driven to an appropriate position according to the detected temperature. A cover plate 12 is arranged between the color panel 5 and the front lighting cover 11, and a slit 13 is provided in the cover plate 12. A light diffusion plate 14 is disposed in front of the slit 13.

The illuminated sign post is formed as described above, and the temperature sensor 4 detects the outside air temperature, so that the color panel 5 is rotated according to the temperature so that a portion having an appropriate color tone faces forward. When the light from the lamp 1 passes through the color panel 5, the light is emitted in a color according to the temperature and illuminated. In other words, according to the outside temperature, it is possible to illuminate with warm colors when the temperature is low and to illuminate with cold colors when the temperature is high. At this time, as shown in FIG. 3, the slits 13 are provided in front of the color panel 5, so that the color mixture is cut so that the mixture of colors is reduced. It is possible to prevent the color change.

[0009]

[Effect of the device]

 As described above, the present invention accommodates a lighting device such as a fluorescent lamp in the lighting portion of the sign post, and a translucent cylindrical color panel whose color tone continuously changes in the circumferential direction is provided around the lighting device. A control that attaches rotatably and controls the temperature sensor that detects the air temperature and the color panel that rotates according to the temperature detected by the temperature sensor so that the part of the color tone corresponding to the temperature faces the surface side of the lighting unit. Since the temperature sensor is used to detect the outside temperature, the color panel rotates accordingly and the color tone according to the temperature is directed toward the surface side of the illumination part and the color according to the temperature is detected. It can emit comfortable light by emitting the light of, and since the color tone of the cylindrical color panel changes continuously, it is possible to prevent the color from changing unintentionally even near the temperature boundary point. It can emit light of various colors and Lamp for structure the panel is rotated changing the color of light emission are those that can easily well-structured one.
