Description

Description: TECHNICAL FIELD The present invention relates to a vertical lighting device, and an object thereof is to be able to use the lighting device on a daily basis frequently in a limited narrow space with a small installation area. By changing the color, size, shape, etc. of the light emitted from the light source, it is possible to project the light with such a high effect with a wide range of projection angles, and to perform this projection over a wide range. An object of the present invention is to provide a vertical lighting device that can be used in a wide range of applications.

The vertical lighting device according to the present invention is used for displays in department stores, stores, exhibitions, stage lighting, production of ceremonies such as weddings, advertising towers, route guidance lights on roads, or warnings at the time of alarm. Can be particularly useful for a wide range of uses.

(Prior art) Conventionally, displays in department stores, stores, exhibitions, stage lighting, production of ceremonies such as weddings, advertising towers, route guidance lights on roads, products at the time of warning at the time of warning, stage, 2. Description of the Related Art Various lighting devices are used to complement or produce ceremonies, people, displays and the like.

Especially in the case of lighting methods that require highly effective lighting such as advertising towers and ceremonies, use a horizontal lighting device with a long focal length to locally illuminate products, people, objects, stages, ceremonies, displays, etc. The method of directing is widely used.

As such an illuminating device, for example, as shown in FIG. 10, there is one in which the converging device portion (b) is long and the size of the entire illuminating device (a) is horizontally long.

However, this illuminating device (a) often causes a problem in use unless a wide place such as the outdoors or a space for installing the illuminating device is secured due to the focal length and the like.

In many cases, the lighting device (a) may be installed on a table depending on the height and size of the object to be radiated, or another device such as a stand (c) may be attached to the lighting device (a). It was necessary to make adjustments, and the overall size of the lighting device (a) was expanded.

Moreover, since the illumination light always illuminates a certain place in a certain shape, the effect of the production was poor and it was difficult for the person to pay attention.

In light of such an actual situation, in Japanese Utility Model Publication No. 46-31512, a xenon lamp having a reflecting mirror is vertically installed on the lower bottom portion of a cylindrical lamp body having a light emitting port, and a lens is provided above the xenon lamp via a lens. There has been disclosed an illuminating device in which a plane reflecting mirror is pivotally mounted on the upper part of a lamp body so as to be rotatable and adjustable.

Further, in Japanese Patent Laid-Open No. 63-29403, a transparent plate for arranging in the light beam as a projection of an image silhouette on a stage, a screen or a background screen, and an image bonded to the surface of this transparent plate, Has an opening with a shape,
A light pattern generating device having a light reflecting layer adapted to pass a part of a light beam passing through the opening to generate a beam having an image shape and to reflect a part of the light beam not passing through the opening. Is disclosed.

Further, in Japanese Utility Model Laid-Open No. 62-57220, a supporting frame is provided in the front of the lamp as a lighting fixture in which the lighting pattern changes, and an annular spring is loosely fitted in the groove of the supporting frame and projected onto the outer peripheral surface of the annular spring. A luminaire with a patterning cap is disclosed.

(Problems to be Solved by the Invention) However, in the lighting device disclosed in Japanese Utility Model Publication No. 46-31512, although the direction angle of the light projected by the flat reflecting mirror can be arbitrarily changed, the lighting device emits light. Since the direction of projection of the dripping light is always constant, the angle of the light can be changed only within a certain range, and there is a problem that the light cannot be projected over a wide range.

Moreover, since the disclosed technique merely changes the projection angle of the light emitted from the xenon lamp in a specific direction, it is not sufficient in terms of effect.

Further, even in the technologies disclosed in JP-A-63-29403 and JP-A-62-57220, the light projected in a specific pattern can be projected, but the projection direction of the light is There is a problem that it is not always sufficient when lighting that has a high production effect such as a ceremony is always constant.

Therefore, a lighting device that can be used frequently on a daily basis in a narrow space with a small installation area,
In particular, by changing the color, size, shape, etc. of the light emitted from the light source, it is possible to project the light with such a high effect of directing at a desired projection angle, and furthermore, to project this light over a wide range. It has been desired to create a vertical lighting device that can be used for a wide range of purposes.
