It is explanatory drawing shown.
The medical lighting apparatus of the present invention includes a plurality (four in this embodiment) of illuminating bodies A and a battery-type power supply device B that supplies power to the illuminating bodies A.
Each illuminating body A has a main body 1 with an LED surface emitting panel 4 attached to the inside of a frame 5 (frame body), and can hold the main body 1 and bend and adjust the position and orientation of the main body 1 by bending. And a support clip 2 that can be bent, and a fixing clip 3 provided at the base end of the support arm 2.

As for the said main body 1, the planar shape is a vertically long rectangular shape, The support arm 2 is connected to the short side part.
The LED surface-emitting panel 4 constituting the main body 1 is obtained by embedding a plurality of LED chips as light sources along the edge of the light guide plate 40, and the light of the LED chip 41 is transmitted to the light guide plate 40, so that the entire panel is uniform. The surface emits light. This LED surface emitting panel 4 can use a well-known thing. The illuminance of the LED surface light emitting panel 4 is not particularly limited, but from the viewpoint of use in medical activities in the field, etc., the illuminance of the LED surface light emitting panel 4 per one illuminating body A is generally about 20000 to 40000 Lx. It is.

The shape and size of the LED surface emitting panel 4 are not particularly limited, but a vertically long shape such as a rectangular shape is preferable from the viewpoint of illuminating a wide area. For example, in the case of a vertically long rectangular shape, it is generally appropriate that the aspect ratio is about vertical dimension / horizontal dimension = 2/1 to 3/1. Moreover, about 300-400 cm < ² > is suitable for the area of the LED surface emitting panel 4 per one illumination body A in general. The thickness of the LED surface emitting panel is usually about 4 to 6 mm. However, it is not limited to the above ranges.
The frame 5 constituting the main body 1 is a frame body that surrounds and holds the LED surface emitting panel 4, and is generally made of a metal or a resin material. As shown in FIG. 4, the frame 5 is configured by a channel-shaped (U-shaped cross-section) member, and the edge of the LED surface-emitting panel 4 is fitted into the groove of the channel-shaped member, whereby the LED surface-emitting panel. 4 is held in the frame 5.

The support arm 2 is a flexible arm that has a bendability and is maintained in a bent (bent) shape, and its tip is joined to a frame 5 constituting the main body 1.
The support arm 2 only needs to be able to freely adjust the position and orientation of the main body 1 by bending. Therefore, in addition to the flexible arm as in the present embodiment, for example, a plurality of arm materials (rigid materials) ) May be sequentially pivoted so that the entire support arm can be bent in different directions at a plurality of pivotal portions.

The fixing clip 3 is a means for fixing and fixing the illuminating body A at a place of use. In this embodiment, the pair of clamp rods 30 that can be opened and closed are urged and closed by the elastic force of a spring. It is made up of things to be made. According to such a fixing clip 3, the illuminating body A can be fixed and fixed at any location as long as there is a base (protruded portion) that can be clamped by the clamp rod 30.
The power supply device B is a battery-type power supply device, and includes a power switch, a converter and the like in addition to the battery, and supplies power to each illuminating body A through the wiring cord 6. In the power supply device B, the battery may be provided separately from a device including a power switch, a converter, and the like.
In the medical lighting apparatus of the present invention, the number of the illuminating bodies A is arbitrary, but generally 3 or more, preferably 4 or more are appropriate.
Moreover, if a solar cell for charging or the like is attached to the medical lighting device, the convenience is further enhanced.

The medical lighting apparatus of the present invention can be used as various illumination lamps for medical use, and is particularly suitable as a treatment lamp or a surgical lamp capable of performing shadowless illumination.
In the medical lighting apparatus of the present invention, normally, a plurality of illuminating bodies A are arranged so as to surround an object to be illuminated or a region, and light is irradiated from the plurality of illuminating bodies A to the object or region to be illuminated. FIG. 5 shows an example of a usage state of the medical lighting apparatus of the present invention, and each illuminating body A is fixed and fixed by clamping an appropriate base portion with the fixing clip 3. In FIG. 5, the table 7 is fixed to the edge, but if there is an appropriate base (protruded portion) that can be clamped by the fixing clip 3, it can be located in any place (for example, in debris). However, the illuminating body A can be fixed and fixed.

Hereinafter, the effect of the medical lighting device of the present invention compared to the conventional medical lighting device will be described.
Conventional medical lighting equipment (treatment / surgical lamps) that use light bulbs (halogen bulbs, etc.) generate heat (the heat of the light bulb itself and the heat generated by light) when trying to ensure sufficient brightness for medical purposes. Therefore, it is necessary to provide sufficient space in the lamp body and to take measures to remove infrared components with a filter, etc., which complicates the structure and increases the volume and weight of the entire device, as well as maintenance. There is a problem such as an increase in burden. Moreover, the cost of the whole apparatus and the running cost will also rise in connection with this. For example, as an example of a portable stand-type surgical light using a light bulb, there is a lightless lighting system using four 50 W light bulbs, and an illuminance of 95000 Lx at a distance of 1 m is obtained. Is as large as 600 mm and the weight is as heavy as 80 kg or more, so it is not easy to carry by hand when used outdoors. In addition, (i) The generator is indispensable for operation because it requires a 100V power source. (Ii) Since the diameter of the illumination lamp cannot be made too large, it is difficult to achieve complete shadowless illumination. However, there is also a problem that (iii) heat is generated even if the above measures are taken, and there is a restriction when used as a surgical light. In addition, as a portable stand-type surgical light with a miniaturized lamp and approaching the surgeon's visual axis to the surgical light axis, the lamp size is 27cm in length and 42cm in width with two 50W bulbs. Although there are those that can obtain 55000 Lx as illuminance in the case of 80 cm, the weight is 80 kg or more including the stand, and a 100 V power source is required like the portable stand-type surgical light.

In contrast, the medical lighting apparatus of the present invention has the following effects.
(A) It is a luminaire using an LED surface-emitting panel, and includes a plurality of illuminating bodies A that can be fixed to an arbitrary base, so that the illuminating body A is arranged and fixed around an illuminated object or region. By this, it is possible to illuminate the object or region to be illuminated with the necessary brightness, and since the LED surface emitting panel illuminates from a plurality of directions, shadowless illumination is also possible. That is, it can be used as an outdoor surgical light.
(B) Since it is illumination by the LED surface emitting panel, there is little generation of heat, and there is no problem even if it is installed near the illuminated object or region for treatment.

(C) The overall volume and weight of the device, including the power supply, is small, does not take up installation space, and is easy to carry. Specifically, the lighting device can be made thin and light enough to fit in the briefcase, and can be lit with a small battery (for example, about 12 V). In addition, it can be quickly deployed and used in the event of a disaster, including the absence of a generator or fuel. Furthermore, since it is small and light, it can be carried as part of a portable medicine, so that it can be used even in a situation where it is buried under debris, for example.
(D) The illuminating body A can be fixed and fixed at any location as long as it has an appropriate base (protruded portion) that can be clamped by the fixing clip 3 of each illuminating body A. For this reason, it can be easily placed and fixed in any place and can be used easily. For example, it can be installed under debris during a disaster.

(E) Since an LED is used as the light source, there are the following advantages.
-Due to the characteristics of the light spectrum, insects are less likely to come close when lit in the outdoors.
-It has robustness that can withstand outdoor use and performance that can withstand shock and vibration in the car.
・ Low power consumption allows long-term use.
-The light source has a long life and is maintenance-free or easy to maintain.

The medical lighting device of the present invention can freely adjust the position and orientation of the LED surface-emitting panel 4 by a support arm made of a flexible arm or the like, and is lightweight as a whole. There is an advantage that the optical axis of the shadowless lamp can be made closer.
In view of the above, the medical lighting device of the present invention is particularly suitable as a treatment lamp or a surgical lamp used for treatment in a field or a temporary tent in a disaster, or treatment in a patient transportation means such as an ambulance or an emergency helicopter. is there.
