In this Patent Document 1, a method of rotating a cylindrical body having a spiral colored surface of red, blue, and white irradiated by a fluorescent lamp by an electric motor and a gear mechanism is replaced with a light emitting diode. An electric motor that rotates the body and a gear mechanism are required. Further, a brush and a slip ring are required as a power supply device for maintaining current supply to the light emitting diode during the rotation, and it is manufactured for a mechanical mechanism. This is a complicated configuration.

It is an object of the present invention to provide a light-emitting display that does not need to be used.

Moreover, in patent document 1, since the light emitting diodes are provided in a spiral arrangement on the outer surface of the cylindrical body,
The mounting and arrangement of the light emitting diodes on the outer surface of the cylinder is troublesome. Furthermore, since the transparent cylinder arranged concentrically with the cylindrical body is arranged, the production of the transparent cylinder increases the cost. The present invention solves such a problem of Patent Document 1 by adopting a new configuration in which a plate-shaped light-transmitting body that replaces this and a light-emitting diode can be mounted on a plate-shaped substrate. Is.

To do.

The cover 3 may have a configuration in which a vertically flat plate-shaped left cover plate 2A and a vertically long flat plate-shaped right cover plate 2B are joined at a central joint 4A. In this case, if the left side cover plate 2A and the right side cover plate 2B are joined to the central joint portion 4A by an opaque joining member, the left side cover plate 2A and the right side cover plate 2B arranged left and right are discontinuous. In order to avoid this, the center joint portion 4A is formed by a method in which the left cover plate 2A and the right cover plate 2B are joined to each other by an adhesive, or a method of joining by a joining member constituted by a translucent member. The left cover plate 2 </ b> A and the right cover plate 2 </ b> B arranged in the left-right direction can be seen as a continuous cover portion 3.

The rear end portions of the left cover plate 2A and the right cover plate 2B are joined to the left side, respectively. The left end portion and the right end portion of the back plate 5 are joined by the portion 4B and the right joint portion 4C. The left joint portion 4B and the right joint portion 4C may have a structure in which the left and right ends of the back plate 5 made of an opaque member such as metal are integrally formed by bending, or a joint formed separately from the back plate 5 The configuration may be such that the rear end portion of the left cover plate 2A and the right cover plate 2B and the left and right ends of the back plate 5 are joined by members.

Similarly to the relationship between the red light emitting element 7R at the lower part of the substrate 6A1 and the red light emitting element 7R at the upper part of the substrate 6A2, the red light emitting element 7R at the upper part of A3 has a linear arrangement connection line that is inclined upward to the right.
With such connection, the arrangement of the red light emitting elements 7R on the substrates 6A1, 6A2, and 6A3 and the output terminals TS1, TS2, and the constant current drive circuits 10A1, 10A2, and 10A3 of the control unit 10
The connection to TS3 is a straight line connection in which the light emitting elements ascend to the right in parallel with equal intervals in the entire substrate 6A. Such connection is the same for the light emitting elements 7B and 7G of the light emitting unit portion 8 of the upper substrate 6A1, the middle substrate 6A2, and the lower substrate 6A3 constituting the left substrate 6A.

In such a connection, the three red light emitting elements 7R on the left and right (total of six) in a straight line arrangement with a diagonally upward right turn on at the same time. Is formed. The control unit 10 emits white light in parallel with the lower side of the red light emission band (or light emission line) formed by lighting the three right and left (six in total) red light emitting elements 7R in a linear arrangement diagonally upward to the right.

In this configuration, a linear white light-emitting band that is slanted to the right is formed.

Then, by the latch signal of the input line L1, O of the output terminals TS1, TS2, TS3
It is the same as described above that the pair of oblique band-like light emission bands (or light emission lines) move upward or downward by switching so that the terminals in the N state sequentially move upward or downward. Further, the switching speed is determined in advance by the control unit 10, and a series of these operations is performed while taking timing (synchronization) with the clock signal of the input line L2.

FIG. 10 also shows the arrangement of the red light emitting element 7R and the control unit 10 among the light emitting elements 7B, 7G, 7R of the light emitting unit 8 of the upper substrate 6B1, the middle substrate 6B2, and the lower substrate 6B3 constituting the right substrate 6B.

Further, by the blue light emitting element 7B of the left substrate 6A and the blue light emitting element 7B of the right substrate 6B,
The same applies to the case where a series of diagonal blue light-emitting bands (or light emission lines) are formed. That is, for example, three blue light emitting elements 7B (in the same position as 7R) surrounded by a dotted frame P11 of the left substrate 6A shown in FIG. 9 and a dotted frame P11 of the right substrate 6B shown in FIG. 3
The blue light emitting elements 7B in series (same position as 7R) are arranged in a straight line when viewed from the front of the light emitting display 1, and when they are simultaneously emitted, a series of diagonally upward straight lines are formed.

The light emitting elements 7B, 7G, and 7R of the light emitting elements 7B, 7G, and 7R simultaneously emit light), and a configuration in which a linear white light emitting band that rises obliquely to the right is formed is the same as described above.

The operation of the light emitting display 1 can be controlled by the remote controller 11. In this case, the control unit 10 receives a wireless signal or an infrared signal emitted from the remote controller 11 by the reception sensor 17, and controls the ON / OFF of the operation of the light emitting display 1 or the light emitting elements 7 </ b> B, 7 </ b> G of the light emitting unit 8. It is possible to change the light emission luminance of 7R, select a light emission pattern (select whether to emit light from the oblique light emission unit portions 8 or to emit light from two oblique light emission unit portions 8), and the like. The control unit 10 senses light around the light-emitting display 1 with the illuminance sensor 18, and when it is bright during the daytime or the like, the light-emitting elements 7B, 7G, and 7R of the light-emitting unit 8 are increased in luminance.
Further, when it is bright at night or the like, the light emission brightness of the light emitting elements 7B, 7G, and 7R of the light emitting unit 8 is lowered, and automatic control is performed so that the light emission state according to the surrounding situation is obtained.

The input line L3 of the constant current drive circuits 10A1, 10A2, 10A3 is connected to the illuminance sensor 1
