Description

  The present invention relates to a table lighting device for nail care that is fixedly arranged on a table between a practitioner seated face to face and, in particular, to a table lighting device for nail care using an LED light source.

  Nail care that performs various cares of nails is known, such as nail art for decorating human hands and toenails. In such nail care, a practitioner and a practitioner are seated facing each other across a table, and various treatments are performed on the table. In many cases, a long fluorescent lamp with a straight tube has been used as an illumination device for this treatment. In other words, nail care requires a certain level of brightness in order to perform detailed work, and it is necessary to illuminate the left and right hands of the patient at the same time by irradiating light to the left and right of the table. This is why. On the other hand, if the size of the fluorescent lamp is increased in order to obtain brightness, the field of view between the practitioner and the patient is obstructed and uncomfortable, and the treatment is performed by ultraviolet rays emitted from the fluorescent lamp. In some cases, the UV curable gel hardened.

  Therefore, in recent years, LEDs are also used as light sources in such nail care desk lighting devices. By using the LED, even if it is used between the practitioner and the practitioner facing each other, the element is small and the light source can be made small. is there. Moreover, since it is a light source with high directivity, the amount of ultraviolet rays can be made smaller than that of a fluorescent lamp while ensuring brightness, and the curing of the gel can be suppressed.

  By the way, if it is going to make the work area irradiated with LED brighter, it will become easy to produce a shadow on the hand of the person who is a work object. In order to eliminate such a shadow, it is considered to irradiate light from a plurality of places on an object, such as using a plurality of light sources like a so-called shadowless lamp.

  For example, Patent Document 1 discloses an illumination device in which a substantially rod-shaped light guide body having a curved tip is attached to a base portion including an LED light source. It is said that light can be emitted from a plurality of locations toward the inside of the curve by using a plurality of diffuse reflection portions arranged inside the light guide to suppress the shadow of the illumination target.

  Patent Document 2 discloses a portable illumination device for performing shadowless illumination. In such an illuminating device, the surface emitting panel by LED is provided in the front-end | tip of the some bendable support arm which provided the clip for fixation in the base end part, and each is connected to the power supply device. Shadowless illumination is possible by attaching respective support arms to a plurality of locations at the end of the table and adjusting the arrangement of each illumination device.

  Patent Document 3 discloses an illumination device for a display in which light emitting devices using a plurality of LEDs are arranged along the extending direction of a flexible tube having flexibility. The flexible tube can be arranged along various shapes such as a shelf, and the usability of the lighting device can be improved. Even in such an illuminating device, since light is irradiated from a plurality of locations, the shadow of the object to be illuminated can be suppressed.

It becomes easy.

It is a side view of the illuminating device by this invention. It is a side view of the principal part of the illuminating device by this invention. It is a perspective view of the principal part of the illuminating device by this invention.

  Hereinafter, one embodiment of a lighting device for nail care according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the illuminating device 10 includes a clip 1 for fixing the illuminating device 10 to an end of a table 9 serving as a work table, and a first support tube 2 having one end fixed to the clip 1. And a round bar-shaped first light 3 having one end fixed to the other end, a second support tube 4 having one end fixed to the other end, and a round bar-shaped first light having one end fixed to the other end. 2 lights 5 and a power cord 6 extending from the clip 1.

  The first support tube body 2 and the second support tube body 4 are so-called flexible tubes having flexibility. For example, the first support tube body 2 and the second support tube body 4 are round tubular bodies in which a metal bellows body is coated with a resin. That is, the first support tube body 2 and the second support tube body 4 can be bent and extended so that the position and the angle can be adjusted while supporting the first light 3 and the second light 5, respectively. It has sufficient rigidity to hold the bent and stretched state, that is, has a resistance to bend and stretch. Furthermore, the rigidity of the first support tube 2 is higher than the rigidity of the second support tube 4.

  Thus, the first support tube body 2, the first light 3, the second support tube body 4, and the second light 5 constitute a series of flexible rod-like bodies, and the intermediate portion thereof. A certain first light 3 and a second light 5 that is a tip portion are respectively set as non-flexible portions. The first support tube 2 and the second support tube 4 have a power cord 6 for supplying power to the first light 3 and the second light 5 inserted therein.

  As shown in FIG. 2, the first light 3 (or the second light 5) includes a light body 31 (51) having a substantially round bar shape made of a resin having translucency and sandwiched from both ends in the axial direction. End member 34 (54) is included. A plurality of LED elements 35 (55) are arranged along the central axis inside the light body 31 (51), and light can be projected from the projection unit 32 (52) on the outer periphery of the light body 31 (51). A reflective seal that reflects light is attached to the inside of the light main body 31 (51) on the opposite side of the projection unit 32 (52) from the axis to form the reflective unit 33 (53). That is, in FIG. 3, light can be irradiated mainly toward the lower side of the drawing. The LED element 35 (55) has a highly directional light and a reflective seal, so that a sufficient amount of light can be secured as a lighting device for nail care. Further, by arranging the LED elements 35 (55) along the axis, the light irradiation range can be widened in the axial direction.

  The LED element 35 (55) is preferably a combination of, for example, elements capable of projecting the three primary colors of light, and further combining an ultraviolet LED element so that light of a plurality of frequencies can be projected. Thereby, the wavelength of the light to project can be adjusted and an ultraviolet light can also be projected.

  Here, referring to FIG. 1 again, the projection unit 32 of the first light 3 and the projection unit 52 of the second light 5 are in the same direction when the second support tube 4 is linearly extended. It is made to face. That is, as shown in FIG. 1, when the second support tube 4 is bent in the direction of the projection unit 32 of the first light 3, the optical axis by the projection unit 52 of the second light 5 is the first The light 3 intersects the optical axis of the projection unit 32 of the light 3.

  As shown in FIG. 3, the clip 1 includes a pair of clip bodies 11 connected by a shaft 14 so that the seesaw can move with respect to each other. The clip body 11 includes a pair of sandwiching portions 12 for sandwiching a fixed portion for fixing the lighting device 10 such as the table 9 and the other end for separating the sandwiching portions 12 from each other. And a pair of gripping portions 13. In addition, a spring (not shown) is provided between the clip main bodies 11 to urge the holding portions 12 in the direction in which they are brought close to each other.

  The first support tube 2 is fixed to the back surface of one clip body 11 by a fixed end 15. The power cord 6 disposed inside the first support tube 2 passes through the one clip main body 11 and is led out toward the grip portion 13 from the other clip main body 11. Note that the fixed end 15 preferably connects the clip 1 so as to be rotatable around the axis of the first support tube 2.

  Next, the usage method of the illuminating device 10 is demonstrated using FIG.

  As shown in FIG. 1, the lighting device 10 is first fixed by a clip 1 to a fixing part such as an end of a table 9. Further, a power supply is secured by inserting a plug (not shown) connected to the power cord 6 into a nearby socket.

  Further, the position and orientation of the first light 3 are adjusted so that light is projected onto the work area on the table 9 by being moved by bending and stretching the first support tube 2. In particular, in the nail care treatment, since the treatment is performed on the right hand and the left hand, it is preferable to easily move the work area from side to side. If the clip 1 is arranged on one of the left and right sides of the work area, it is preferable that the optical axis of the first light 3 can be moved left and right only by bending and extending the first support tube 2. At this time, the practitioner and the practitioner are respectively positioned in front of and behind the page, and face each other with the table 9 interposed therebetween.

  Next, the position and orientation of the second light 5 are adjusted by bending and extending the second support tube 4 so as not to cause a shadow on the object illuminated in the work area. That is, the direction is adjusted so that the optical axis of the first light 3 and the optical axis of the second light 5 intersect each other in the vicinity of the work basin, and the distance from the two to the work area is made equal to balance the amount of light. Adjust it. Here, since each of the first light 3 and the second light 5 is a rod-shaped light source that is long in the axial direction, a work area can be set wide in the left-right direction, and a shadow is applied to the subject's hand that is the object. It is easy to adjust the optical axis in the left-right direction so that it does not occur. Further, as described above, the projection unit 32 of the first light 3 and the projection unit 52 of the second light 5 are directed in the same direction when the second support tube 4 is extended linearly. Therefore, the adjustment can be easily performed by bending and extending the second support tube 4 in a plane including the optical axis of the first light 3. Thus, the work area can be suitably illuminated when performing a fine work in the nail care treatment accurately.

  Here, as described above, the rigidity of the first support tube 2 is higher than the rigidity of the second support tube 4. Thus, even if the second support tube 4 is bent and stretched after the position and orientation of the first light 3 are adjusted by bending and stretching the first support tube 2, the first support tube 2 is It is not bent and stretched. That is, the position and orientation of the second light 5 can be changed without changing the position and orientation of the first light 3, and adjustment can be performed more easily.

  Moreover, the wavelength of the light irradiated by the LED element 35 is adjusted, the wavelength of the light from the light source is adjusted according to the surrounding environment, or the wavelength of the light is adjusted so that the decoration applied to the nail of the patient can be easily seen. Can do. Moreover, it is also possible to cure the ultraviolet curable gel during or after the treatment by irradiating with ultraviolet rays as necessary.

  In addition, the illuminating device 10 is not suitable for using a fluorescent lamp as a light source. Fluorescent lamps contain a lot of ultraviolet light and promote unintended gel curing. Moreover, since the straight fluorescent lamp can irradiate uniform diffused light in the axial direction, it is suitable for suppressing the shadow in the axial direction on the object to be illuminated. That is, even if two straight fluorescent lamps are connected in the axial direction in the same manner as the lighting device 10 described above, the effect of eliminating the shadow cannot be obtained any more. On the other hand, by arranging two straight tube fluorescent lamps in parallel, it is possible to obtain an effect of eliminating the shadow in the direction orthogonal to the axial direction.

  On the other hand, in the illuminating device 10 according to the present embodiment using the LED element 35, the first light 3 alone has a high light amount even if a plurality of light sources are arranged along the axis of the rod body, and It is easy to produce shadows with highly directional light. Therefore, the shadow of the object illuminated by the light emitted from the second light 5 is erased.

  Further, in the lighting device 10, the first support tube 2 to the second light 5 form a series of rod-like bodies. Further, since the first light 3 and the second light 5 are LED elements 35 and 55 as light sources, they can be configured to have a thin rod-like body. One end of the rod-like body is fixed to one of the left and right sides of the space between the practitioner and the operator, and extends upward, and further extends toward the other of the left and right. That is, even if it is arranged in a narrow space between the practitioner and the practitioner, the space on the practitioner side and the practitioner side that is a direction intersecting with the extending direction of the rod-shaped body can be widened. Thereby, a large space can be given to a practitioner and a practitioner who face each other within a reachable distance. That is, the lighting device 10 using a rod-shaped body does not hinder the treatment. Furthermore, since the rod-shaped body is thin, it does not block the view of the operator and the patient and does not hinder the operation, and is comfortable.

  It should be noted that the lighting device 10 can be fixed not only to the table 9 but also to various parts around the position to be used as the work area by the clip 1 so as not to hinder the treatment.

  After the treatment, the practitioner can push up the series of rods upward with one hand. That is, the first support tube body 2 and the second support tube body 4 are extended. Thereby, the illuminating device 10 can be easily opened so as not to interfere with other operations.

  When the clip 1 can be rotated around the axis of the first support tube 2 at the fixed end portion 15, the above-described work area can of course be arranged on the table 9 as shown in FIG. For example, the work area can be arranged outside the table 9 by rotating the rod-shaped body with respect to the clip 1. As described above, when the lighting device 10 is fixed to various parts, if the fixed end portion 15 is rotatable, the projection unit 32 of the first light 3 and the projection unit 52 of the second light 5 are used. It becomes easy to orient in the intended direction.

  As mentioned above, although the Example by this invention and the modification based on this were demonstrated, this invention is not necessarily limited to this, A person skilled in the art will deviate from the main point of this invention, or the attached claim. Various alternative embodiments and modifications could be found without doing so.
