[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foot lighting device that illuminates a foot.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is known a foot lighting device that illuminates a foot with low illuminance at night and helps a user walk, etc. without feeling dazzling especially when waking up at night. Such a foot luminaire is conventionally configured such that a light bulb is used as a light emitter and switching between on / off is performed by a switch operation.
[0003]
[Problems to be solved by the invention]
Since the conventional foot luminaires as described above are configured to be switched on / off by a switch operation, normally, when the lamp is turned off, the switch operation is performed in a dark state when it is about to turn on. Difficult to do. Therefore, if the light is always turned on at night, the troublesome operation of the switch described above can be solved, but this is not preferable from the viewpoint of energy saving because of the increased power consumption.
[0004]
In order to solve the above problem, it is conceivable to detect a person and automatically switch on / off.
As such switches that detect a person and automatically switch on / off, for example, thermal sensor switches described in Japanese Patent Laid-Open Nos. 9-82188 and 9-50749 are known. This thermal sensor switch is configured to detect a heat ray radiated from a heat radiation body such as a person, strictly speaking, a human body, and to switch on / off a lighting fixture or the like.
[0005]
Therefore, the inventor of the present application considered applying the thermal sensor switch described in the above publication to the above-described lighting fixture as the first stage of the invention. By configuring in this way, it is possible to use such that the lighting is normally turned off at night, and the lighting is automatically turned on for a certain time only when a person comes. Operation is unnecessary and convenient, and power consumption can be reduced.
[0006]
However, as described above, even when the conventional lighting device is switched on / off by the conventional thermal sensor switch, there are problems to be solved as listed below.
B) Since it is necessary to provide a foot luminaire and a thermal sensor switch, installation takes time and the number of parts increases, which is disadvantageous in terms of cost.
B) When illuminating the feet, if the illumination light is directed upwards, people who have moved from dark places will feel dazzling. Especially, people who have reduced pupil adjustment ability, such as elderly people. When going to the bathroom in the middle of the night, once the light enters the eyes, the pupils may not be adjusted in time and may feel dazzling and may be invisible for a while. For this reason, it has been desired to provide a structure that reliably illuminates only the foot without diffusing the illumination light upward, but this has not been achieved sufficiently in the past.
C) As for the lighting equipment for the feet, the one using a light bulb as described above is generally used, and with use, the light bulb breaks, and it is necessary to replace the light bulb each time. It takes. In addition, it is necessary to take safety measures at the time of replacing the light bulb, resulting in a complicated configuration and an increase in cost.
[0007]
The present invention was made paying attention to the above-mentioned problems to be solved, and in addition to making it possible to reduce the power consumption and eliminate the troublesome operation of the switch in the foot lighting device, By integrating the lighting function of the foot and the function of the thermal sensor, the number of parts and installation time are reduced, and the illumination light is condensed in the foot direction without directly entering the human eye. Thus, the main purpose is to improve the antiglare performance and the foot lighting performance, and it is also intended to improve the maintainability and simplify the configuration without replacing the bulb.
[0008]

According to this configuration, it is possible to improve the lighting performance by collecting the light of the light emitter in the foot direction, which is a preferable direction for the foot lighting device, without undue diffusion by the arc-shaped inclined wall. .
[0013]
Further, as described in claim 3, in claim 1 or 2 feet luminaire according, the light emitting body, preferably constituted by a white LED. According to this configuration, it is not necessary to replace the light bulb, so that the maintainability can be improved, and the safety measures corresponding to the replacement of the light bulb are not required, and the configuration can be simplified.
[0014]
Further, as described in claim 4 , in the foot illuminator according to claims 1 to 3 , it is preferable that the connection terminal of the power source is disposed on the back surface of the inclined wall.
[0015]
Further, as described in claim 5 , in the foot illuminator according to claims 1 to 4 , it is preferable that an optical sensor is provided in parallel with the thermal sensor on the substrate. According to this configuration, it is possible to detect a state where it is unnecessary to cause the light emitter to emit light by the optical sensor, and to prevent unnecessary lighting even if a person is detected.

Further, in the present embodiment, a white one is used as the lamp hood 10, but it may be colored in other colors as necessary.
[0022]
Further, as shown in FIG. 3, a partition wall 31 is formed in the horizontal direction integrally with the shielding wall 33, and the inside of the cover 3 is partitioned vertically by the partition wall 31.
[0023]
A substrate 7 having electronic components is installed inside the container 1. The substrate 7 is configured by arranging a first substrate 7a and a second substrate 7b substantially in parallel. On the front surface of the first substrate 7a, a light emitting body 71 made of a white LED, a thermal sensor 72 for detecting heat rays, An optical sensor 73 for detecting light, and in the installed state, the thermal sensor 72 and the optical sensor 73 are disposed on the upper side of the partition wall 31 so as to face the upper opening 32a. A light emitter 71 is disposed below the partition wall 31 so as to face the inner surface of the shielding wall 33.
[0024]
Further, the cover 3 is formed with an inclined wall 34 at a position below the light emitter 71 and facing the lamp hood 10 (lower opening 32b). The inclined wall 34 reflects the light of the light emitter 71 and guides the indirect light obliquely downward through the lamp hood 10 (lower opening 32b), and does not diffuse the indirect light outside a predetermined range. As shown in the drawing, the front surface is inclined upward and is formed in an arc shape having a depressed center as shown in FIG.
[0025]
On the back side of the inclined wall 34, connection terminals 4 and 4 for connecting an electronic circuit provided on the substrate 7 and a power source are provided. As shown in FIG. 1, these connection terminals 4 and 4 are provided with protrusions 42 formed by cutting and raising provided on the front surface and columnar protrusions 43 in engagement holes 75 and 76 formed in the first substrate 7a. The protrusion 42 is inserted and soldered to a circuit pattern of an electronic circuit formed around the engagement hole 76 and fixed. In each connection terminal 4, the presser springs 5, 5 and the release member 6 are incorporated, and are accommodated in the terminal accommodating portion 21 of the case 2 in the assembled state. The presser springs 5 and 5 clamp the lead wires outside the drawing inserted from the lead wire insertion holes 23 provided on the back side of the case 2 shown in FIG. 4 in cooperation with the gripping pieces 41 of the connection terminals 4. The release member 6 is a member for releasing the holding of the conducting wire by bending the presser spring 5 by inserting a tool such as a screwdriver from a tool insertion hole 24 provided on the back side of the case 2. Further, in the case 2, reference numeral 22 denotes a substrate storage unit 22 that stores the second substrate 7 b.
[0026]
Next, the electronic components provided on the substrate 7 will be briefly described. The electronic components control the lighting / extinguishing of the light emitter 71. That is, when the thermal sensor 72 detects a person (heat ray), the electronic component performs control to turn on the light emitter 71 for a predetermined time from that time, and to turn off the light emitter 71 otherwise. At the same time, the lighting control is performed only when the light sensor 73 is dark, such as at night, when the amount of light exceeding a predetermined level is not detected.
[0027]
The foot illuminator A configured as described above is installed and used indoors, for example, at a low position near the floor in a hallway connecting a bedroom and a toilet. When installing the foot lighting device A of the present embodiment, the lighting part and the thermal sensor part are installed at the same time, and the mounting workability is excellent compared to the case where these are separated, and the number of parts It is possible to reduce costs and reduce costs.
[0028]
Also, the foot lighting device A automatically illuminates the foot by illuminating the light-emitting body 71 only at the time of detecting a person at night, so that there is no troublesome operation of the switch and it is lit only when necessary. Power consumption can be reduced.
[0029]
At the time of lighting, the light from the light emitter 71 travels outside the container 1 through the lamp hood 10, and in this case, as shown in FIG. The light reflected by 31 and directed downward and the light reflected by the inclined wall 34 and directed downward are directed downward as shown, and this light does not travel upward.
Therefore, the illumination range can be narrowed down to the feet, and the user does not feel the illumination light dazzling at night. This is particularly effective when the user is a person with reduced pupil adjustment function, such as an elderly person. By the way, for people with reduced pupil adjustment function, if the pupil enters the eye while waking up, the light cannot be closed instantly, so it feels very dazzling. At the same time, the eye is invisible for a while, and in this embodiment, such a state can be reliably prevented.
[0030]
Furthermore, in the present embodiment, the range illuminated by direct light at the time of lighting is narrowed by the shielding wall 33 and the lower opening 32b and illuminated by indirect light by the inclined wall 34 and the partition wall 31. By adopting widely, it is easy lighting with reduced illuminance. Therefore, this also provides high antiglare performance and increases the degree of freedom in setting the illuminance.
[0031]
In addition, in the present embodiment, since the inclined wall 34 for obtaining the indirect light is formed in an arc shape as described above, the illumination range is narrowed without diffusing the illumination range in the horizontal direction. This also provides high anti-glare performance and enhances the product quality as a foot lighting device.
[0032]
Further, in the present embodiment, since a white LED is used as the light emitting body 71, it is not necessary to replace the light bulb as compared with the case where a light bulb is used, and the maintenance performance is excellent. A configuration for safety measures at the time of replacement (for example, a configuration that detects when the bulb is replaced and cuts off electricity) can be omitted, and cost reduction can be achieved.
[0033]
In addition, the foot lighting device A of the present embodiment is provided on the plate D together with the outlet B, and is optimal for being provided in a place such as a corridor where the outlet and the foot lighting are necessary. Can also be omitted.
[0035]
