Some display devices with illumination include a human sensor for turning on the illumination device when a person approaches when the illumination device is turned off at night.
By providing a human sensor in the illuminated display device, the human sensor detects the person when the lighting device is turned off at night, and the lamp is detected based on the detection signal of the illuminance sensor. Can be turned on at sunset to illuminate a display portion such as a display panel.

In such a display device with illumination, the illuminance sensor and the human sensor are arranged in the housing of the display device in order to protect them from wind and rain.
When using these illuminance sensors or human sensors, it is necessary to provide an opening in the housing to ensure the detection range of the sensor.
If a separate opening is provided in order to secure the detection range of the sensor, the appearance deteriorates, so the drain hole provided in the bottom of the housing is also used as the sensor opening.

However, the drain hole is often provided at an arbitrary location by an operator at a construction site where the display device is installed.
For this reason, the operation | work which provides the drain hole in the position which corresponds with the position of an illumination intensity sensor or a human sensitive sensor has become complicated.

  The present invention has been made to satisfy the above-mentioned demands, and the purpose thereof is to provide an illumination device that can simplify the work at the installation site where it is installed and can reliably match the sensor in the housing with the drain hole. It is to provide a display device.

  The display device with illumination of the present invention is a display device with illumination comprising an illumination unit, a housing having an opening for housing the illumination unit, and a display panel provided in the opening of the housing, The illumination unit includes a light source that illuminates the display panel, a lighting circuit that controls the lighting of the light source, a mounting substrate that supports the light source, and an illuminance sensor or a human sensor for controlling the lighting of the light source. The housing has at least one sensor, the housing has a drain hole, and the detection range of at least one sensor of the illuminance sensor or the human sensor and the drain hole overlap. The mounting position of at least one sensor is supported so as to be variable.

At least one of the illuminance sensor and the human sensor was provided, and the sensor was supported so that the mounting position of the sensor was variable.
Thereby, since the position adjustment of the sensor can be easily performed, the work of overlapping the hole and the detection range of the sensor becomes easy.

  According to the display device with illumination of the present invention, the position of the sensor can be easily adjusted, so that the work at the installation site to be installed can be simplified, and the sensor in the housing can be surely matched with the drain hole. Has an effect.

Hereinafter, a display device with illumination according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 2, the display device with illumination 10 of the first embodiment is a signboard lamp used in a store or a station, and includes an illumination unit 12 and an opening 15 that accommodates the illumination unit 12. A housing 14 and a display panel 16 provided in an opening 15 of the housing 14 are provided.

The housing 14 includes a back wall 21, left and right side walls 22 (see FIG. 4 for the left side wall 22), a top 23 provided at each upper end of the back wall 21 and the left and right side walls 22, the back wall 21, and the left and right side walls 22. Are formed in a box shape at the bottom 24 provided at each lower end, and an opening 15 is formed at a portion facing the back wall 21 (that is, a portion corresponding to the surface).
A drain hole 26 for draining water is formed in the bottom 24 of the housing 14.

A display panel 16 is provided in the opening 15 of the housing 14.
The display panel 16 is a member provided at a location corresponding to the surface of the housing 14, and is a plate material on which characters or pictures for display are drawn and light emitted from the illumination unit 12 can be transmitted.

  The lighting unit 12 includes a lamp (light source) 28 that irradiates the display panel 16, a lighting circuit 29 that controls lighting of the lamp 28, a reinforcement channel (mounting substrate) 31 that supports the lamp 28 and the lighting circuit 29, and a reinforcement channel 31. The left and right fixed channels 33 provided horizontally in the lower part 31A of the first and second slide channels 35, a slide channel 35 spanned between the left and right fixed channels 33, and an illuminance sensor 38 supported by the slide channel.

The reinforcing channel 31 is a substrate that is provided on at least the left and right sides of the back wall 21 of the housing 14 and supports the lamp 28 and the lighting circuit 29.
Left and right fixed channels 33 are horizontally provided at lower ends 31A of the left and right reinforcing channels 31, respectively.

The left and right fixed channels 33 are members having a substantially U-shaped cross section that extend horizontally from the lower ends 31A of the left and right reinforcing channels 31 toward the opening 15 of the housing 14 (that is, the display panel 16). .
The left and right fixed channels 33 are arranged in parallel on the bottom 24 of the housing 14.
Slide channels 35 are spanned between the left and right fixed channels 33.

As shown in FIGS. 3 to 4, the slide channel 35 is a member having a substantially U-shaped cross section disposed in parallel with the bottom 24 (see also FIG. 2) of the housing 14.
The slide channel 35 is attached to be movable in the XX direction along the longitudinal direction of the fixed channel 33.

As a method of attaching the slide channel 35 so as to be movable in the X-X direction, for example, long holes 41 are formed in the left and right fixed channels 33 along the longitudinal direction.
And the slide channel 35 is attached to each long hole via the bolt 42 and the nut 43 (refer FIG. 2).
By loosening the bolt 42, the slide channel 35 can be moved in the XX direction along the longitudinal direction of the long hole 41, that is, the fixed channel 33.

The illuminance sensor 38 is attached so as to be movable in the YY direction along the longitudinal direction of the slide channel 35.

As a method of attaching the illuminance sensor 38 so as to be movable in the Y-Y direction, for example, a long hole 45 is formed in the slide channel 35 along the longitudinal direction.
An illuminance sensor 38 is attached to the long hole 45 via a bolt 46 and a nut (not shown).
By loosening the bolt 47, the illuminance sensor 38 can be moved in the YY direction along the longitudinal direction of the long hole, that is, the slide channel 35.

As described above, the slide channel 35 is attached to be movable in the XX direction, and the illuminance sensor 38 is attached to be movable in the YY direction, so that the illuminance sensor 38 is moved in the XX direction and the YY direction. It can be movably supported.
Therefore, the illuminance sensor 38 can be arbitrarily moved in the two-dimensional direction along the bottom 24 of the housing 14.

  Thus, by moving the illuminance sensor 38 in the XX direction and the YY direction, the illuminance sensor 38 can be positioned so that the detection range of the illuminance sensor 38 overlaps the drain hole 26.

As a result, the position adjustment of the illuminance sensor 38 can be easily performed, so that the work of overlapping the hole and the detection range of the sensor is facilitated.
Therefore, it is possible to simplify the work at the construction site where the installation is performed, and to reliably match the sensor in the housing with the drain hole.
