Description

The present invention relates to a lighting device, and more particularly to a lighting device suitable for cosmetological treatment and other work in a beauty salon and the like, and photography thereof.

Conventionally, as a lighting device for taking a picture of a person, for example, a half-body image taking device disclosed in Patent Document 1 is known. The bust imaging device of the same document covers a square front frame that can be moved by casters, a plurality of lights provided at least on the top, bottom, left, and right of the front frame, and the upper surface of the lower light among these plurality of lights. It has a diffuser plate. The light has a cylindrical shape and includes a xenon tube for a strobe and a modeling lamp inside the diffuser plate.

According to the bust imaging device of the same document, it is possible to easily capture a bust of a person by freely moving the front frame provided with a plurality of lights at predetermined positions, and it is possible to perform high-level lighting. it can. In addition, the light rays from the lower light are diffused through the diffuser plate to become soft light rays that soften the shadows under the chin, so that a half-body image in which the light is sufficiently rotated can be photographed.

Further, as an example of another prior art, Patent Document 2 describes a first frame on the front side and a second frame on the rear side, which are rotatably attached, and a light source attached to the first or second frame. A photographing assisting device including a light diffusing cover stretched over the first and second frames is disclosed. In this device, in a state where the first and second frames are fixed to each other while maintaining a predetermined angle in the front-rear direction, the first and second frames and the cover form a shooting space with an open front surface. Then, the light emitted from the light source is irradiated into the shooting space through the cover.

However, the lighting devices of the prior art disclosed in Patent Documents 1 to 3 are all devices for taking photographs, and are suitable for cosmetological treatments and other operations in beauty salons and the like and their photography. It wasn't a thing. Therefore, in order to use the conventional lighting device in a beauty salon or the like, there are some points to be improved.

Specifically, in the above-mentioned conventional lighting device, a space for a worker such as a beautician who performs a cosmetology to work in a lighting environment is not considered. For example, in the half-body image photographing apparatus disclosed in Patent Document 1, the desk portion integrally fixed to the front frame interferes with the work by a beautician or the like. Further, in the photographing assisting device disclosed in Patent Document 2, it is difficult to secure a space for a beautician or the like to enter inside the photographing space formed by the first and second frames and the cover. Further, in the photographic lighting device disclosed in Patent Document 3, since the right side and the left side are blocked by the light emitting wall, the movement of the beautician, the cart, etc. entering and exiting the lighting space is hindered.

Further, all of the lighting devices disclosed in Patent Documents 1 to 3 are configured on the assumption that they are photographed only from the front side, and appropriately irradiate the back side of the subject with light. I can't. That is, the lighting device of the prior art could not suitably irradiate the head of the user who is the object of cosmetology with light from all directions when performing cosmetology in a beauty salon or the like. In particular, since it was not possible to clearly illuminate the condition of the beautified hair in the lower part of the back of the head of the user, the conventional lighting device was not suitable for cosmetic treatment or the like.

In addition, a device that uses a flash from a strobe device, such as a conventional technique disclosed in Patent Document 1 or a general lighting device for photography, cannot continuously illuminate an irradiation target. Therefore, conventional lighting devices that utilize flashes are unsuitable as lighting for cosmetology and other work. In addition, a lighting device that emits a flash of light is not suitable as lighting for continuously shooting a moving image of a situation where cosmetology is performed.

In addition, Patent Document 3 discloses that constant light is used. However, the photographic lighting device of the same document uses a rod-shaped lamp, and the lamp is arranged in a light emitting wall unit on a substantially flat plate. Therefore, for example, the distance from the irradiation target such as the head of the user sitting in the illumination space to the lamp differs depending on the direction with respect to the irradiation target. Therefore, this type of lighting device has a problem that it is difficult to uniformly irradiate the irradiation target with light from all directions, and the brightness tends to be uneven depending on the direction. Therefore, the above-mentioned lighting device for photography is insufficient as a lighting device for cosmetology, which is required to clearly show the flow and overlap of hair in all directions of the head to be treated. ..

The present invention has been made in view of the above circumstances, and an object of the present invention is to be able to uniformly illuminate an irradiation target from all directions with suitable brightness and color tone, and for beauty in a beauty salon or the like. The purpose is to provide a lighting device suitable for treatment and other work and their photography.

The lighting device of the present invention includes a support frame having a plurality of columns erected on an installation surface, an upper frame provided above the support frame, and a plurality of suspension members suspended from the upper frame, and a spherical light source. A plurality of light source units having a cap body covering a part of the light source and attached to the holding member, and the light source unit opens the cap body toward an irradiation target below the upper frame. A plurality of the light source units are arranged on at least one of the hanging members, and the light source unit at the lowermost portion emits light from diagonally below with respect to the irradiation target. It is characterized by irradiating.

According to the lighting device of the present invention, the light source unit has a support frame having a support column erected on an installation surface, an upper frame provided above the support frame, and a plurality of suspension members suspended from the upper frame. Is suspended from the upper frame of the support frame via a suspension member. As a result, it is possible to form a lighting space having a size suitable for a worker such as a beautician to work under the upper frame. In addition, the surroundings of the lighting space are not blocked by walls, etc., and only the columns are erected on the installation surface, and there are no other obstacles, so the movement of beauticians, carts, etc. may be hindered. It is easy to get in and out of the lighting space.

Further, the plurality of light source units suspended from the upper frame by the suspension member are arranged in a dome shape so that the cap body covering the light source opens toward the irradiation target. It has a cap body that covers a part of the light source, and the opening of the cap body is directed to the irradiation target, so that a part of the light emitted from the light source is reflected and diffused by the cap body and is irradiated to the lower part of the upper frame. Is preferably irradiated. By arranging the light source units in a dome shape, it is possible to uniformly irradiate the irradiation target with light from a plurality of light source units arranged so as to surround the irradiation target. For example, it is possible to illuminate the head of a user who is the object of irradiation and the object of cosmetology with substantially uniform brightness and with few shadows not only in the front part but also in all directions such as the side part and the rear part. .. In addition, the configuration in which a plurality of light source units are arranged in a dome shape has the advantage that sufficient illuminance suitable for cosmetology can be obtained and the glare felt by users, beauticians, etc. can be reduced. ..

Further, according to the lighting device of the present invention, the light source units may be arranged so that the distances from the respective light sources to the irradiation target are equal. As a result, the light can be uniformly irradiated to substantially the entire circumference such as the front, back, left and right of the irradiation target.

Further, according to the lighting device of the present invention, the hanging member may be supported so as to be rotatable or linearly movable with respect to the upper frame. As a result, the light source unit can be moved by rotating the lower part of the holding member suspended from the upper frame so as to lift it upward, or by sliding the holding member in a substantially horizontal direction. With such a configuration, the position of the light source unit can be changed as needed to facilitate work by a beautician or the like and access to a lighting space such as a beautician or a cart.

Further, according to the lighting device of the present invention, a translucent screen that is attached to the upper frame and can be deployed and stored between the light source and the irradiation target may be provided. Thereby, the screen can be expanded or retracted according to the situation, and the irradiation of the light to the irradiation target can be appropriately adjusted. For example, the screen on the opposite side of the surface to be irradiated or photographed can be lowered to appropriately suppress backlight unnecessary for work or photography.

Further, according to the lighting device of the present invention, a light diffuser which is attached to the cap body and closes a part of the opening of the cap body may be provided. As a result, the direct light from the light source can be blocked and diffused by the light diffuser, and the partial brightness of the irradiation target can be suitably adjusted. For example, by providing a light diffuser so as to block the path of light reflected directly from the light source to the user's face, especially near the eyes, or by being reflected by a mirror or the like, an antiglare effect can be obtained and the user can use it. You can reduce the glare you feel.
