[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention, for example, to a lighting device for use in mounting the hospital bed head side or wall side or the like.
[0002]
[Prior art]
For example, when reading on a desk or performing various operations on a work table, a lighting device such as a table stand is prepared in addition to the room light, and the lighting device is turned on to partially illuminate locally to provide a predetermined brightness. The lighting environment is secured to enhance the visibility of the object, and various operations can be performed easily and reliably.
[0003]
As such a lighting device, for example, on a desk top surface, a device in which a spotlight is directly attached in a state where the head can be swung to a certain angle, a flexible light bent in a letter shape, and the like are known. If such a lighting device is used, the illumination light can be relatively concentrated and projected toward a desired portion.
[0004]
[Problems to be solved by the invention]
In such a lighting device, the transparent region is restricted to some extent and the irradiation region of the light to be projected is narrowed, but it is used only as a partial illumination, and fine work on a desk surface, for example, a local illumination light is used. It is not possible to easily perform the work by narrowing down to a very small distance.
[0005]
As lighting equipment in hospitals and the like, in addition to room lights embedded in ceilings and the like, for example, similar lighting equipment (spotlights, flexible lights, and the like) for patients to read books and the like are known. However, even with such a lighting device, for example, in the case where local care work (treatment) is performed at night, the care work (treatment) is performed in a dim light because the illumination light does not reach the desired affected part well. In addition, the interior lights must be turned on to disturb the sleep of other patients in the same room during sleep, so that care work (treatment) must be performed.
[0006]
In particular, in the case of a flexible light or the like, the light source can be moved within a certain range.However, since the light emitted from the light source is not sufficiently stopped, the affected part is illuminated with the diffused light, so that work can be performed. In some cases, the required brightness cannot be obtained (there is a risk of obstructing the treatment).
[0007]
In view of the above circumstances, the present invention switches between an illumination state in which diffused light is emitted according to work preference and an illumination state in which local illumination / light emission is performed by switching with a simple operation. An object is to provide a lighting device that can be easily performed.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a lighting device in which a base is attached to a tip portion of an arm via a swing mechanism, and a cover is attached to the base. The cover is rotatably held, and an umbrella-shaped heat shield plate is fixed in the cover so as not to rotate with the rotation of the cover. A light source is fixedly mounted on a socket provided at a position avoiding the above, and a light-transmitting member having an uneven area subjected to diffusion processing and a transparent area not subjected to diffusion processing is fixed to the opening of the cover, Providing a reflecting mirror to cover the light source, irradiating the light controlled by the reflecting mirror as spot light when the transparent area is positioned under the light source by rotating the cover, and rotating the cover. light source Irradiating the diffused light when positions the irregular region down, the part of the outer peripheral surface of the cover is provided with a handle for changing the rotational position of the cover.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows an illuminating device according to a first embodiment of the present invention. The illuminating device is also applicable to a wall surface of a hospital room (of a hospital or a clinic) (a head side of a bed, for example, a headboard or a floor stand). An arm 1 is attached to W), and a base 3 is attached to the tip of the arm 1 via a swing mechanism 2 that can freely move in a direction orthogonal to XYZ. The cover 5 is rotatably attached to the base 3 so that the center of the surface facing downward is the center of rotation of the cover 5.
[001 0 ]
The arm 1 is formed in a substantially letter shape, and is bent downward from an intermediate portion so that the light projecting position can be freely moved forward, backward, left and right. The arm 1 has substantially cylindrical joints which can be turned in the vertical direction at three positions of a base, an intermediate part and a distal end. A swing mechanism 2 is attached. An appropriate mounting portion 8 is provided at the base end of the arm 1, and the arm 1 is mounted on the wall surface W of the sick room with the mounting portion 8.
[001 1 ]
As shown in FIG. 2, the swing mechanism 2 is configured to move vertically, horizontally, and horizontally via three axes (not shown) provided in the X, Y, and Z directions between the distal end of the arm 1 and the base of the base 3. The light source 4 can rotate in three-dimensional directions with respect to the arm 1. Reference numeral 22 denotes a fixed knob.
[001 2 ]
The base 3 shown in FIG. 3 is configured to hold the cover 5 by a holding plate 34 described later provided at the tip . As is clear from FIG. 3, a holding plate 34 is attached to the shaft of the base 3, and a heat shield plate 31 is fixed to a tip portion of the shaft . Further, a socket 32 is fixedly provided at an arbitrary position other than the center of the heat shield plate 31.
[001 3 ]
The cover 5 has a substantially trumpet (cylindrical) shape in which the front end side is widened. In this embodiment, the cover 5 is 180 degrees with respect to the outer peripheral surface of the base 3 (in the present invention, the angle is not limited to this angle, and an arbitrary range is set. (Applicable). The light source 4 is attached to the socket 32. The light source 4 does not rotate with the rotation of the cover 5, and is fixedly attached to the position shown in FIG.
[001 4 ]
The opening of the cover 5, as shown in FIG. 3, the translucent member 51 is opening having an uneven areas subjected to diffusion treatment (may be constituted by a frosted glass) by fine roughened (51 B) , And is made of, for example, tempered glass or the like. Further, this position off the center of the translucent member 51, as shown in FIG. 4, is provided with a part only diffusion processing is not subjected to the transparent region 51 A. The transparent region 51 A has a light controlled by the reflecting mirror 33 is transmitted through, so as to irradiate light having a light distribution of locally narrow angle such as the affected area (spot light). A louver 52 formed in a substantially lattice shape is provided outside the light transmitting member 51. A hood 54 that is cut diagonally is attached to the open end of the cover 5.
[001 5 ]
Furthermore, a handle (operating operation) that has a substantially U-shape on a part of the outer peripheral surface of the cover 5 and allows the patient and a medical practitioner such as a doctor or a nurse to freely grip and change the rotational position of the cover 5. (Constituting means) 6. In other words, the movement of the cover 5 by the handle 6 allows the light projection state of the light from the light source to be switched between two types (a state in which the light from the light source is diffused and a state in which the light is narrowed down). A power switch S for turning on / off the power is attached to the cover 5 near the mounting portion of the handle 6. Further, the group member 3, dimmer switch for adjusting the illumination intensity of the light by the light source 4 in two steps (not shown) has been attached, this does not particularly needed.
[001 6 ]
Therefore, according to this embodiment, for example, as shown in FIG. 5, when the patient P raises his / her upper body from the bed and reads a newspaper or a book, the arm is extended and the handle 6 is grasped with one hand, The power switch S may be turned on by operating the arm 1 and pulling the cover 5. As a result, as shown in FIG. 6, the light from the light source 4 enters the frosted glass portion (the uneven region 51B) of the light transmitting member 51 immediately below, so that the soft diffused light L1 can illuminate the patient's hand or the like brightly. .
[001 7 ]
On the other hand, when the caregiver A or the nurse performs an appropriate operation, for example, observing the affected part or changing a bandage, as shown in FIG. 6, the arm 1 is operated, the cover 5 is pulled to the side, and the handle 6 is rotated by about 180 degrees. Thus, as shown in FIG. 8, since the transparent region 51 A of the tempered glass is to be positioned directly below the light source 4, it is possible to project a bright spot of light L2 from the light source to a desired site in direct patient it can.

【The invention's effect】
As described above, according to the present invention, in the lighting device in which the base is attached to the tip of the arm via the swing mechanism, and the cover is attached to the base, the holding plate is provided at the tip of the base. The cover is rotatably held by the holding plate, and an umbrella-shaped heat shield plate is fixed inside the cover so as not to rotate with the rotation of the cover. A light source is fixedly mounted on a socket provided at a position avoiding a certain central portion, and a light-transmitting member having an uneven area subjected to diffusion processing and a transparent area not subjected to diffusion processing is fixed to an opening of the cover. Then, a reflecting mirror is provided so as to cover the light source, and when the transparent area is positioned under the light source by rotating the cover, light controlled by the reflecting mirror is irradiated as spot light, and the cover is rotated. Movement Allowed by the diffused light is irradiated when the positions the irregular region below the light source, since there is provided a handle for changing the rotational position of the cover portion of the outer peripheral surface of the cover, depending on the preference of the user Anyone can switch between multiple lighting modes very easily.
[00 19 ]
Thus, in particular, for example when used in etc. hospitals and nursing homes in the vicinity of the bed, the hand when manipulating care assistant with uneven surface is rotated on hand of the patient is positioned on the emission optical path of the light source When turned, the transparent area is located on the emission optical path of the light source and the emitted light is projected on the affected part, so that the irradiation state can be switched by a very simple operation such as turning the handle near the hand . As a result, for example, when a patient uses for reading, etc., diffused light is incident and processed into soft light that does not burden the patient's eyes, and when nurses etc. provide care assistance Enables bright and local spot illumination and projection to the affected area.
