Description

  The present invention relates to a lighting device that illuminates a floor surface such as a foot.

  Conventionally, for example, in a hospital room in a hospital or a medical room of a medical welfare facility, when a patient goes to a toilet or the like at night, a nightlight or a footlamp is installed to prevent the room from being dark, and the patient is made safe.

  In this type of night light, a night light is provided on a luminaire installed on the ceiling of the room, or a foot lamp is installed below the wall surface to light up at night.

  However, in these lighting fixtures, light may enter the eyes of a patient sleeping in a bed and feel dazzling, which may prevent the patient from sleeping.

  In addition, foot lamps are usually installed on a wall surface about 300 mm above the floor surface, but patient beds in hospitals etc. are usually installed with the pillow side facing the wall surface. It was difficult to illuminate the entire floor, and there was no way to illuminate the feet in the patient's bed extensively at night.

  Therefore, a lighting system that illuminates the feet on the side panel of the bed, detects the movement of the patient, and turns on the footlamp only when the patient moves off the bed. (For example, refer to Patent Document 1).

Also, in general homes, there is known a lighting device installed on a handrail in order to effectively illuminate the feet of stairs and corridors (for example, see Patent Document 2).

  The lighting fixture 10 includes a gripping member 20 and a light source unit 11.

  First, the configuration of the light source unit 11 will be described with reference to FIGS. 1 and 2.

  The light source unit 11 includes a light source 12 and a main body case 13 that houses the light source.

 The light source 12 is a light-emitting diode (hereinafter referred to as “LED”), and in this embodiment, the light source 12 is composed of one white LED from which light is mainly emitted to the optical axis aa of the LED.

  The LED 12 is mounted on a disc-shaped printed wiring board with a chip element having a primary lens as a central part, and is inserted into a light input end of a lens body 12a to constitute a light emitting element 12b.

  The light emitting element 12b configured as described above is inserted and mounted inside a cylindrical light shielding body 12c made of synthetic resin or the like to constitute the light emitting portion 12d. The light emitting unit 12d is mounted at a substantially intermediate portion of the light blocking body so that light does not leak in the peripheral direction, and is arranged so that a cylindrical light blocking portion (shade) 12e is formed in front of the lens body 12a.

  Accordingly, the light emitting unit 12d using the LED 12 as a light source is configured to perform spot light distribution by the lens body 12a and the light shielding body 12c. The spot light distribution angle θ1 is preferably 15 to 45 degrees.

  The main body case 13 houses the light shielding body 12c to which the light emitting element 12b is mounted. The main body case 13 is composed of a cylindrical body having one end made of synthetic resin or the like, and the cylindrical light shielding body 12c is inserted into the open portion. In the state where the open portion of the light-shielding body and the open portion of the light shielding body are matched, the fixing is performed using a fixing means such as a screw or a heat-resistant adhesive such as silicone resin. The open part of the light shielding body 12c may be closed with a transparent plate made of transparent glass or synthetic resin.

  Thereby, the cylindrical central axis of the main body case 13 coincides with the optical axis aa of the LED, and the optical axis xx of the light source unit 11 is configured.

  In the space portion of the main body case 13, component parts 12e constituting an LED lighting circuit are incorporated.

  Reference numeral 14 denotes an attachment member for attaching the main body case 13 to a lower end portion of a gripping member 20 described later. In this embodiment, the other end portion of the main body case 13 is formed as a hemispherical spherical body.

  As described above, the cylindrical center axis of the main body case 13 is the optical axis xx of the light source unit 11, the light emitting unit 12 d using the LED 12 as a light source is configured at one end, and the light source unit 11 including the attachment member 14 is configured at the other end. Is done.

  The light source unit 11 having the above configuration is attached to the lower end portion of the handrail 20 to constitute the lighting fixture 10.

  That is, the handrail 20 constitutes the gripping member of the present invention, is constituted by a strong synthetic resin pipe, has a support portion 20a at one end, and is substantially L-shaped in a substantially right angle direction from the support portion. A grip 20b is formed by bending, and the other support 20d is formed integrally with the lower end of the grip, and the other support 20d is formed as a whole to form a handrail having a substantially U shape.

  The light source unit 11 is attached to the handrail 20 configured as described above.

  That is, as shown in FIG. 1, the attachment portion 20c formed at the lower end portion in the longitudinal direction of the handrail grip portion 20b is formed in a hook-like shape by cutting off the upper half of the cross section of the synthetic resin pipe having a circular cross section. It is configured.

  A fitting member 14 made of a hemispherical spherical body formed at the other end of the main body case 13 is fitted into the hook-shaped attachment portion 20c, and the shaft pin 30 is attached to one of the attachment portions 20c of the handrail. The spherical body of the instrument body is passed through, and is further pivoted through the other side of the handrail mounting portion 20c.

  Accordingly, the light source unit 11 is attached to the lower end portion of the handrail 20 so as to be able to rotate over a predetermined angle θ2 in the front-rear direction with respect to the vertical line zz (wall surface C) of the handrail.

  In this embodiment, the angle θ2 is configured to be rotatable over an angle range of about 60 degrees from the vertical line zz of the handrail, and the light source unit 11 is previously centered on the shaft pin 30 within the range of the angle θ2. It is set so that the spot light distribution of the light source unit 11 illuminates a portion D that becomes a foot while the patient is seated on the bed.

  Next, the lighting fixture 10 in which the light source unit 11 is set on the handrail 20 as described above is installed in each bed of the medical room A.

  As shown in FIG. 4, a plurality of beds B are installed in the nursing room A, and a handrail 20 is installed on a vertical wall C close to the head of the bed.

  The handrail 20 is installed with a distance dimension s from a position away from the extension line yy on the side of the bed, that is, a position D where the patient gets up from the bed and sits on the bed and becomes a foot.

  The handrail 20 is disposed on the wall surface C corresponding to the above-described position with one support portion 20a on the top and the other support portion 20d on the bottom, and the longitudinal direction of the grip portion 20b is a vertical line z-z along the wall surface Cz. It is installed so that it is parallel to the top and is a vertical handrail located on the bed head.

  As a result, when the patient gets up from the bed, the operation is facilitated by gripping the handrail grip 20b, which is vertically installed on the bed head, so that the patient can easily get up.

  Thereby, as shown in FIG. 5, the lighting fixture 10 of the said structure is each installed in the vertical direction on the wall surface C corresponding to the several bed B installed in the nursing room A (4 units in a present Example). The

  Although the power source of the light source unit 11 is not shown, a wiring cord is drawn from the wall surface C, passes through the other support portion 20d (downward) of the handrail 20, and is made of a hemispherical spherical body of the main body case 13. A wiring cord is introduced into the main body case 13 through the back surface of the member 14 and supplied to the lighting circuit of the LED 12.

  Further, since the lighting fixture 10 is used as a step lamp at night, it is OFF when the main lighting such as the ceiling lighting fixture is turned on during the day and at night, and is turned off when the main lighting is turned off at night and the main lighting is turned off. Furthermore, it is controlled in conjunction with a lighting control device or the like. It may be ON / OFF with a manual switch.

  As described above, the handrail 20 having the height dimension H of about 600 mm and the support sections 20a and 20d having the height dimension h of about 150 mm is installed in the vertical direction on the wall surface C close to the head of each bed B of the treatment room A. A lighting fixture 10 is configured in which a light source unit 11 having a spot light distribution performance with a length L of about 100 mm is installed below the handrail.

  The operation of the above-configured lighting fixture will be described.

  The lighting fixture 10 is OFF during main day lighting such as a ceiling lighting fixture during daytime and nighttime.

  At night, when the treatment room A is turned off, the main illumination is turned off, the light emitting unit 12d of the light source unit 11 is turned on, and the portion D that is a foot while the patient is seated on the bed on the side of the bed B is illuminated.

  At this time, since the light source unit 11 is set to be inclined obliquely toward the front, the light emitted from the LED light source is radiated toward the portion D which is a foot while the patient is seated on the bed, and The light source unit 11 uses an LED 12 with high directivity as a light source, and is irradiated with spot light distribution by the lens body 12a and the light shielding body 12c. Therefore, the light source unit 11 has a wide elliptical range E ( 4 (b) can be illuminated, and only the necessary feet are illuminated in a wide range along the side surface of the bed B. At this time, since the floor surface on the side of the bed B is irradiated with spot light distribution, light does not reach other than the feet, and the sleeping patient does not feel dazzling.

  Further, the light source unit 11 is set to be inclined in a direction away from the wall surface C, and is further spaced apart from the wall surface by the height dimension h of the handrail support portions 20a and 20d from the wall surface C, so that the light is applied to the wall surface. Reaching is suppressed, and no glare is felt from the wall surface.

  When the patient goes to the toilet at night, he can easily get up by gripping the handrail grip 20b installed vertically on the wall surface of the bed head, and slippers can be placed while sitting on the bed. The foot D on the side of the bed is lit reliably.

  As a result, the patient can get out of the bed while visually checking the place to get off, and can safely get off the bed and go to the toilet without tripping in the dark.

  Also, when returning from the toilet, the feet on the side of the bed are similarly reliably illuminated, and the feet can be confirmed and returned safely to a predetermined position on the bed.

  When it becomes brighter in the morning, the luminaires 10 in the treatment rooms are turned off all at once in conjunction with the lighting control device.

  Further, when the irradiation position is changed in accordance with the patient's height or the like, a necessary position is obtained by grasping the distal end portion of the light source unit 11 and adjusting the angle over an angle range of about 60 degrees from the vertical line zz. Set to. This work is performed, for example, when the nurse or patient turns on the lighting device at night.

  As described above, according to the present embodiment, the light source unit 11 uses the LED 12 as a light source, and the lens body 12a and the light shielding body 12c irradiate with spot light distribution. Thus, it can illuminate in a wide range E having an elliptical shape, and can sufficiently fulfill the function as a foot lamp that illuminates only a necessary foot in a wide range.

  In particular, since the LED 12 having high radiation light directivity is used as the light source, a more effective spot light distribution is possible, and the light source unit 11 is also a small light source that is not subject to restrictions such as installation space problems. The part 11 can be provided, and installation is possible even at a small space installation location on a handrail, handle, or the like.

  In addition, since the body case 13 is attached to the gripping member 20 so that the inclination angle of the optical axis xx can be varied by the attachment member 14, the light source unit 11 can be set obliquely and set in a spot arrangement. A wide light distribution range E having an elliptical shape by light can be obtained with certainty.

  In addition, the elliptical light distribution range E by spot light distribution is configured to be able to rotate over an angle range of about 60 degrees from the vertical line zz, so that it is necessary to adjust the angle at a necessary position. It can be reliably set within a certain range. In addition, this operation can be performed easily and easily even by a patient himself / herself or a nurse who is not used to handling this type of equipment.

  Further, since the light is irradiated with the spot light distribution, the light does not reach other than the necessary feet, and the sleeping patient does not feel dazzling.

  In addition, the light source unit 11 is inclined and set in a direction away from the wall surface C, and is further disposed away from the wall surface, so that light is suppressed from reaching the wall surface and does not feel dazzling from the wall surface.

  Since the main body case 13 is attached to the lower part of the handrail 20 by the attachment member 14, the light source unit 11 can be installed in the lower part of the room, and only the necessary feet can be more reliably illuminated and more reliably dazzled. It can be made not to feel it.

  At the same time, since it is attached at a position away from the handrail grip 20b, the light source 11 does not get in the way when it grips the handrail, and the light source 11 does not hinder the function as a handrail.

  As described above, it is possible to provide a lighting fixture that does not cause the patient to feel dazzling while sufficiently fulfilling the function as an original footlamp, and can provide a lighting fixture that does not hinder the function of the handrail.

  Further, as shown in Patent Document 2, when a lighting fixture is installed on the handrail itself, the lighting fixture itself must also have a handrail function, and a strong lighting fixture must be configured. According to the embodiment, it is not necessary for the lighting fixture to have a function as a handrail, and it is not necessary to provide a strong strength, and it is possible to provide a lighting fixture that is advantageous in terms of cost.

  In addition, when a lighting fixture is installed on the handrail itself, there is a risk of electric shock due to a direct grip of the lighting fixture in the event of a leakage, etc. According to this, the handrail and the lighting fixture are completely separated from each other, and the light source unit 11 is attached to the lower end of the gripping member that is not directly gripped by the hand. An excellent lighting fixture can be provided.

  In addition, assembling work of the light source unit 11 to the handrail 20 is performed by simply fitting the light emitting unit 12d, the lighting circuit unit 12e, and the like as the assembled light source unit 11 into the handrail mounting unit 20c, and using the shaft pin 30 as a shaft. Assembling can be performed by a simple work to be supported, and the assembling workability can be easily performed at the installation site, and a lighting apparatus having excellent workability can be provided.
