Abstract

PROBLEM TO BE SOLVED: To provide an illumination device capable of suppressing the occurrence of self-on/off even when a plug or an electric wire is connected.SOLUTION: A body 20 which can be mounted on an elevation surface 11 is mounted on the elevation surface 11 in such a manner that a sensor region RA comes above a light emitting region RB and a non-light emitting region RC. Therefore, in the case where the light emitting region RB is arranged below the sensor region RA, and the non-light emitting region RC is arranged below the light emitting region RB, even when a white-based plug and the like is connected to the non-light emitting region RC and the light from the light emitting region RB is reflected, a brightness sensor 28 on the opposite side of the non-light emitting region RC does not detect the reflection light. Also, in the case where the non-light emitting region RC is arranged below the sensor region RA and the light emitting region RB is arranged below the non-light emitting region RC, when the white-based plug 43 and the like is connected to the non-light emitting region RC, the light from the light emitting region RB is shielded by the plug 43 and the like, so that the reflection light from the plug 43 and the like is not detected. Thereby, a malfunction due to the detection of the reflection light from the plug 43 and the like can be prevented, and the occurrence of self on-off can be suppressed.

Description

  The present invention relates to an illuminating device that automatically senses when the surroundings are dark, such as at night, and illuminates the feet.

Conventionally, there is known an illumination device that detects brightness near the front by a brightness sensor, turns on a light source to illuminate the feet when the surroundings are dark, and turns off the light source when the surroundings are bright (for example, Patent Document 1).
As shown in FIG. 8, an LED footlight (illumination device) 100 described in Patent Document 1 is used by being embedded in a wall surface 101. The LED foot lamp 100 has an LED 102 as a light source at a lower portion and a brightness sensor 103 at a central portion. The LED foot lamp 100 has an outlet 104 on the upper side of the brightness sensor 103.
Further, the LED footlamp 100 has a decorative cover 105 on the outer peripheral portion, and a lens 106 in front of the LED 102.

Accordingly, when the brightness sensor 103 senses that the surrounding area has become dark, for example, in the evening, the LED foot lamp 100 turns on the LED 102 to illuminate the foot.
At this time, by passing the lens 106, the irradiation direction of the LED 102 is set to a substantially non-front direction so that the reflected light from the wall surface facing the front does not enter the brightness sensor 103.
As a result, the light emitted from the LED 102 that has been controlled to be turned on once prevents the brightness sensor 103 from turning off by recognizing that the surrounding has become brighter, and repeating this.

JP 2002-289031 A (FIG. 1)

However, as shown in FIG. 9, in the conventional LED footlight 100 (illumination device) as described above, a white plug 107 and an electric wire (not shown) may be connected to the outlet 104 in some cases.
At this time, when the light LB1 is irradiated from the LED 102 to the floor surface 108, a part of the irradiated light LB1 is reflected by the floor surface 108 (light LB2).
Then, a part of the reflected light LB2 hits the plug 107 or the like, and there is a problem that a part of the reflected light LB3 is detected by the brightness sensor 103 and self-flashing may occur.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide an illumination device that can suppress the occurrence of self-flashing even when a plug and an electric wire are connected.

  The lighting device of the present invention, a main body that can be attached to the vertical surface, a light emitting region that is supported by the main body and faces away from the vertical surface, a non-light emitting region that is disposed adjacent to the light emitting region, A sensor region that is disposed adjacent to one of the light-emitting region and the non-light-emitting region and has a brightness sensor that detects brightness on the side opposite to the elevation surface, and the brightness supported by the body. And a controller that turns on the light emitting area corresponding to the brightness detected by the sensor, and the main body is attached to the vertical surface so that the sensor area is above the light emitting area and the non-light emitting area. It is possible.

  In the illumination device of the present invention, the sensor region is disposed adjacent to the light emitting region on the opposite side to the non-light emitting region.

  In the illumination device of the present invention, the sensor region is disposed adjacent to the non-light emitting region on the opposite side to the light emitting region.

  Furthermore, in the illumination device of the present invention, an outlet is provided in the non-light emitting area.

  In the present invention, the illuminating device is attached to the elevational surface so that the sensor region is above the light emitting region and the non-light emitting region. Therefore, when a light emitting area is arranged below the sensor area and a non-light emitting area is arranged below the light emitting area, a white plug or the like is connected to the non light emitting area to reflect light from the light emitting area. However, the brightness sensor on the opposite side of the non-light emitting area does not detect a plug or the like. In addition, when a non-light emitting area is arranged below the sensor area and a light emitting area is arranged below the non-light emitting area, if a white plug or the like is connected to the non-light emitting area, the light from the light emitting area is plugged. The plug is not detected. Accordingly, it is possible to provide a lighting device that can prevent malfunction due to detection of reflected light from a plug or the like and suppress the occurrence of self-flashing.

(First embodiment)
Hereinafter, a lighting device according to a first embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the illumination device 10 </ b> A according to the first embodiment of the present invention is attached to a lower portion of a wall surface (elevation surface) 11 and can be used to illuminate the floor surface 12.
In the following description, the floor 12 side will be the bottom and the opposite side will be the top.

As shown in FIGS. 1 and 2, the lighting device 10 </ b> A includes a mounting bracket (main body) 20 that can be mounted in a mounting hole (not shown) provided in the wall surface 11.
The mounting bracket 20 has a rectangular plate-like base 21, and four sides are bent forward (irradiation direction) to form ribs 22. A rectangular first opening 23 is provided at the center of the base 21, and a rectangular second opening 24 is provided below the first opening 23.
In addition, the left and right outer edge portions of the first opening 23 are provided with attachment portions 25 that are bent rearwardly (back side of the base 21). Therefore, the mounting bracket 20 is fixed by mounting the mounting portion 25 in the mounting hole of the wall surface 11.

The first opening 23 of the base 21 accommodates and attaches a rectangular box-shaped case 26 opened forward (opening 261). A control board (control unit) 27 is attached to the opening 261 of the case 26.
A brightness sensor 28 is attached to the top of the control board 27. The brightness sensor 28 is controlled by the control board 27 and sends a detection signal to the control board 27. The brightness sensor 28 is preferably located at the end in the width direction.
A pair of protrusions 271 protruding forward are provided at both left and right ends of the control board 27.

  A rectangular plate-shaped light source unit 29 is attached to the protrusion 271 of the control board 27, and the light source unit 29 is controlled to be turned on by the control board 27. A rectangular frame 292 is provided at the center of the light source unit 29, and an LED 31 that is a light source is attached inside the frame 292. A pair of attachment holes 293 are provided on the upper side of the frame 292.

Further, a through hole 291 is provided at a position corresponding to the brightness sensor 28 of the control board 27 in the light source unit 29, and the brightness sensor 28 can protrude forward. A black cylinder 32 is attached to the through-hole 291 to protect the brightness sensor 28 protruding from the light source unit 29 and prevent light from entering from the side.
The black cylinder 32 is opaque and the inner surface is black. Thereby, the malfunction of the brightness sensor 28 is prevented. A lens 33 that covers the front of the brightness sensor 28 is attached to the tip of the black cylinder 32.

  A rectangular box-shaped terminal block 34 is accommodated and attached to the second opening 24 of the base 21. An outlet 35 is provided on the front surface of the terminal block 34.

A rectangular plate-like cover 36 is attached to the rib 22 of the base 21. The cover 36 accommodates the light source unit 29 and the terminal block 34 attached to the front surface of the case 26 and covers the front surface of the mounting bracket 20.
A round hole 37 for the brightness sensor 28 is provided in the upper part of the cover 36, and a part of the lens 33 projects forward from the round hole 37.
In this way, the sensor region RA for detecting brightness is formed in the upper part of the front surface of the cover 36.

A rectangular first opening 38 is provided at the center of the cover 36, and the frame 292 of the light source unit 29 fits inside the first opening 38. A milky white translucent panel 39 is disposed in the first opening 38. A pair of mounting pieces 391 project from the upper portion of the panel 39, and the mounting pieces 391 are inserted into the mounting holes 293 of the light source unit 29 so that they can be opened and closed.
Locking protrusions 392 are provided on the lower portions of both side surfaces of the panel 39 so as to protrude outward, and are locked in a closed state when the panel 39 is attached and closed.
In this manner, a light emitting region RB that emits illumination light is formed adjacent to the lower side of the sensor region RA on the front surface of the cover 36.

A rectangular second opening 41 is provided at the bottom of the cover 36. The second opening 41 is located in front of the terminal block 34, and the outlet 35 portion is inserted so that the front surface of the outlet 35 is exposed in front of the cover 36.
In this way, a non-light emitting region RC that does not emit illumination light is formed adjacent to the lower side of the light emitting region RB on the front surface of the cover 36.

Next, operation | movement of 10 A of illuminating devices is demonstrated.
The illuminating device 10A is attached to the lower part of the wall surface 11, for example. When the brightness sensor 28 in the sensor area RA detects that the area on the side opposite to the wall surface 11 (front side) has become dark, the control board 27 turns on the LED 31 provided in the light source unit 29 in the light emitting area RB. Let Thereby, the panel 39 emits light and illuminates the floor surface 12 on the opposite side (front side) to the wall surface 11.
Further, when the brightness sensor 28 in the sensor area RA detects that the surrounding area has become bright, the control board 27 turns off the LED 31 in the light emitting area RB.

  At this time, as shown in FIG. 3, for example, when a white plug 43 is inserted into the outlet 35, the light LBA 1 emitted from the light source unit 29 in the light emitting region RB hits the upper surface of the plug 43 and is reflected upward. (Reflected light LBA2). The reflected light LBA2 is reflected upward, but is not detected by the brightness sensor 28 in the sensor area RA.

The effect of 10 A of illuminating devices of 1st Embodiment which concerns on this invention is demonstrated.
The mounting bracket 20 that can be attached to the wall surface 11 includes a light emitting region RB, a non-light emitting region RC, and a sensor region RA.
The light emitting region RB is supported by the mounting bracket 20 and faces the opposite side (front side) from the wall surface 11. The non-light emitting region RC is disposed adjacent to the light emitting region RB. The sensor region RA is disposed adjacent to one of the light emitting region RB and the non-light emitting region RC, and has a brightness sensor 28 that detects the brightness on the side opposite to the wall surface 11.

Then, the control board 27 supported by the mounting bracket 20 turns on and off the light emitting region RB corresponding to the brightness detected by the brightness sensor 28. At this time, the mounting bracket 20 is attached to the wall surface 11 so that the sensor region RA is above the light emitting region RB and the non-light emitting region RC.
As a result, when the light emitting region RB is disposed below the sensor region RA and the non-light emitting region RC is disposed below the light emitting region RB, the white plug 43 or the like is connected to the non light emitting region RC to emit light. Even if the light from the region RB is reflected, the brightness sensor 28 on the opposite side of the non-light emitting region RC does not detect the plug 43 or the like.

Further, when the non-light emitting region RC is disposed below the sensor region RA and the light emitting region RB is disposed below the non-light emitting region RC, when the white plug 43 or the like is connected to the non-light emitting region RC, the light emission occurs. Since the plug 43 etc. blocks the light from the region RB, the plug 43 etc. is not detected.
As a result, malfunction due to detection of reflected light from the plug 43 or the like can be prevented, and the occurrence of self-flashing can be suppressed.

The sensor region RA is disposed adjacent to the light emitting region RB on the opposite side to the non-light emitting region RC. That is, the light emitting region RB is located below the sensor region RA, and the non-light emitting region RC is located below the light emitting region RB.
Therefore, as shown in FIG. 3, even when a white plug 43 or the like is connected to the non-light emitting region RC and the light from the light emitting region RB is reflected, the brightness sensor 28 on the opposite side of the non-light emitting region RC. Does not detect the plug 43 or the like.

Furthermore, since the outlet 35 is provided in the non-light emitting region RC, the plug 43 and the electric wire can be connected to the outlet 35. At this time, even if a white plug or the like is connected to the outlet 35, the brightness sensor 28 does not detect the plug or the like because the sensor region RA is located on the opposite side of the non-light emitting region RC across the light emitting region RB.
For this reason, malfunction due to detection of reflected light from a plug or the like can be prevented, and occurrence of self-flashing can be suppressed.

(Second Embodiment)
Next, the illuminating device of 2nd Embodiment which concerns on this invention is demonstrated.
In addition, the same code | symbol is attached | subjected to the site | part which is common in 10 A of illuminating devices of 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.
As shown in FIG. 4, in the illumination device 10 </ b> B of the second embodiment, the outlet 35 (see FIG. 1) is not provided in the non-light emitting region RC, and the lid 42 is attached.

As described above, according to the illuminating device 10B of the second embodiment of the present invention described above, the sensor region RA is located above the light emitting region RB. For this reason, the brightness sensor 28 is difficult to detect reflected light from the floor surface 12 when the light emitting region RB illuminates the floor surface 12.
Thereby, generation | occurrence | production of self-flashing can be suppressed.

(Third embodiment)
Next, the illuminating device of 3rd Embodiment which concerns on this invention is demonstrated.
In addition, suppose that the same code | symbol is attached | subjected to the site | part which is common in the illuminating device 10A of 1st Embodiment mentioned above, and the illuminating device 10B of 2nd Embodiment, and the overlapping description is abbreviate | omitted.
As shown in FIG. 5, in the illuminating device 10C of the third embodiment, two outlets 35 are provided in parallel in the non-light emitting region RC.
Therefore, parts such as the mounting bracket 20 and the cover 36 are wider than the lighting device 10A of the first embodiment.

As described above, according to the illuminating device 10C of the third embodiment of the present invention described above, it has the same operations and effects as the illuminating device 10A of the first embodiment described above, and a white plug or the like is connected to the outlet 35. Even so, the occurrence of self-flashing can be suppressed.
Moreover, since there are many outlets 35, the utility value as a power supply improves.

(Fourth embodiment)
Next, the illuminating device of 4th Embodiment which concerns on this invention is demonstrated.
In addition, the same code | symbol is attached | subjected to the site | part which is common in the illuminating device 10A of 1st Embodiment mentioned above-the illuminating device 10C of 3rd Embodiment, and the overlapping description is abbreviate | omitted.

As shown in FIG. 6, the illumination device 10 </ b> D of the fourth embodiment has a non-light emitting region RC in which an outlet 35 is provided at the center. The sensor region RA is provided above the non-light emitting region RC, and the light emitting region RB is provided below the non-light emitting region RC.
That is, the sensor region RA is arranged adjacent to the non-light emitting region RC on the opposite side to the light emitting region RB.

  As shown in FIG. 7, for example, when a white plug 43 is inserted into the outlet 35, the light LBD 1 emitted from the light source unit 29 in the light emitting region RB is irradiated downward and hits the floor surface 12. (Reflected light LBD2). The reflected light LBD2 goes upward, but hits the plug 43 and is blocked, so that the sensor 28 in the sensor area RA does not detect this.

  As described above, according to the illuminating device 10D of the fourth embodiment of the present invention described above, the same effect and effect as those of the illuminating device 10A of the first embodiment described above can be obtained. Even when connected, the occurrence of self-flashing can be suppressed.

The lighting device of the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
That is, in each embodiment mentioned above, although the case where it used as a foot lamp attached to a wall surface was illustrated, it does not restrict to this. For example, it can be used for passages, corridors, stairs, etc., whether indoors or outdoors.
