By being arranged near the outer peripheral surface of the panel portion 2 and engaging with the outer peripheral panel portion 2 in a substantially outer fit state, the end panel portion 4 and the outer peripheral panel portion 2 are relative to each other in a plan view (top view). The position is positioned within a predetermined range. Further, the central protruding portion 43 of the end panel portion 4 is arranged near the inner peripheral surface inside the light source unit 1 and is engaged with the light source unit 1 in a substantially inwardly fitted state, whereby the end panel portion 4 The relative position of the light source unit 1 and the light source unit 1 in a plan view is positioned within a predetermined range.
As a result, the relative position of the light source unit 1 and the outer peripheral panel portion 2 in a plan view (top view) can be positioned at a regular use position having a predetermined range.
That is, the outer protruding portion 42 and the central protruding portion 43 of the end panel portion 4 are arranged above or below the light source unit 1 and the outer peripheral panel portion 2, and are flat surfaces of the light source unit 1 and the outer peripheral panel portion 2. The positioning unit 4A for positioning the relative position of the visual view (top view) to the normal use position is configured.

Therefore, the distance between the light emitting surface S1 of the light source unit 1 and the seat support surface S2 of the outer peripheral panel portion 2 can be made substantially equal between the respective parts in the circumferential direction to obtain an appropriate set interval P having a predetermined range. It is possible to appropriately exert the light effect of the period. Incidentally, in the present embodiment, the normal use position is set so that the center of the outer peripheral panel portion 2 and the center of the light source unit 1 are the same or close to each other in a plan view.

Further, as shown in FIG. 2, in a state where each end panel portion 4 is arranged above and below the light source unit 1 and the outer peripheral panel portion 2, the outer protruding portion 42 of the end panel portion 4 is used for directing. It is arranged outside each of the lower edge portion 3A and the upper edge portion 3B of the sheet 3, and the detachment movement of the lower edge portion 3A and the upper edge portion 3B to the outside is prevented from contacting.
That is, the outer protruding portion 42 of the end panel portion 4 is detachably installed on the seat support surface S2 of the outer peripheral panel portion 2 in a state of being arranged above or below the light source unit 1 and the outer peripheral panel portion 2. It constitutes a sheet holding portion 4B which is arranged outside the lower edge portion 3A or the upper edge portion 3B of the sheet 3 and prevents the lower edge portion 3A or the upper edge portion 3B from coming off from the outside.
Therefore, it is possible to efficiently prevent the effect sheet 3 from being unexpectedly detached from the seat support portion S2 of the outer peripheral panel portion 2.

Next, the change of the height dimension (elevation size) of the light effect device of the present invention will be described.
As shown in FIG. 3, when the height dimension of the light effect device is changed, a plurality of light source units 1 are assembled in a continuous state along the vertical direction to emit light having a desired height dimension. The surface S1 can be configured. Then, a plurality of light source units 1 assembled in a continuous state in the vertical direction, an outer peripheral panel portion 2'manufactured corresponding to the height dimension of the light emitting surface S1, and manufactured corresponding to the height dimension of the light emitting surface S1. By assembling the effect sheet 3'and the pair of upper and lower end panel portions 4, it is possible to easily configure an optical effect device having a desired height dimension.

At this time, if necessary, an intermediate positioning panel unit 5 for positioning the relative positions of the upper and lower light source units 1 in a plan view can be interposed between the upper and lower light source units 1.

For example, the intermediate positioning panel portion 5 includes a disk-shaped panel body 51 having an outer shape (outer diameter in this example) larger than the outer shape of the upper and lower light source units 1, and a light source unit on the lower side from the central portion of the panel body 51. A lower protruding portion (lower positioning portion) 52 projecting to one side and an upper protruding portion (upper positioning portion) 53 projecting toward the light source unit 1 on the upper side from the central portion of the panel main body 51 are provided. be able to.

In this way, in a state where the intermediate positioning panel portion 5 is interposed between the upper and lower light source units 1, the lower protruding portion 52 of the intermediate positioning panel portion 5 is internally fitted into the lower light source unit 1 and By fitting the upper protruding portion 53 of the intermediate positioning panel portion 5 into the upper light source unit 1, the relative positions of the upper and lower light source units 1 in a plan view can be positioned within a predetermined range.

Next, a change in the diameter dimension (an example of the plane size) of the light effect device of the present invention will be described.
When changing the diameter dimension of the light effect device, if only the diameter dimension of the sheet support surface S2 of the outer peripheral panel portion 2 is changed while keeping the outer shape of the light emitting surface S1 of the light source unit 1 (an example of the plane size), the sheet The distance between the effect sheet 3 installed on the support surface S2 and the light emitting surface S1 of the light source unit 1 changes, and the effect sheet 3 has insufficient light or excessive light, resulting in a desired light effect. It may not be obtained.

Therefore, as shown in FIG. 4, in the case of responding to the change in the diameter dimension of the light effect device, when assembling a plurality of flat light source plates 11 constituting one side of the light emitting surface S1 in the circumferential direction, the light effect is produced. The number of sheets to be assembled is changed according to the target plane size of the device, and the diameter dimension of the light source unit 1 is changed in the form of changing the number of angles of the polygon.

In this way, the distance between the light emitting surface S1 and the seat support surface S2 can be maintained at the set interval P regardless of the diameter dimension of the light effect device. Incidentally, FIG. 4A shows a case where the three light source plates 11 are assembled into a triangle in a plan view, and FIG. 4B shows a case where the four light source plates 11 are assembled into a quadrangle in a plan view. FIG. 4C shows a case where eight light source plates 11 are assembled into a quadrangle in a plan view.

Then, the light source unit 1 configured as described above, the outer peripheral panel portion (not shown) manufactured according to the diameter dimension of the light effect device, the effect sheet (not shown), and the pair of upper and lower end panels (not shown) are attached. By assembling, a light effect device having a desired diameter can be easily configured. Therefore, it is possible to easily configure a light effect device having a desired diameter dimension while avoiding a problem that a desired light effect cannot be obtained due to insufficient light amount or excessive light amount.
