  The present invention relates to an optical ornament having the appearance of a candle. More specifically, the present invention has a thin plate having a flame shape, and an LED installed so as to illuminate the thin plate from substantially obliquely. It relates to optical ornaments.

  There are known optical ornaments and lighting devices that imitate traditional lighting fixtures using light emitted from LEDs. Since the light source of old lighting fixtures is mainly flames, the inventions and devices of such “optical decorations and lighting devices using LEDs” have many inventions and devices of how to reproduce flames.

  In addition, various “old lighting fixtures” have been adopted in order to increase the value mainly as a decoration in modern times. Such can include candles, lanterns, torches, lighting fixtures having them, and the like.

  Patent Document 1 describes an optical member having an incident portion where light from an LED enters, a scattering portion that scatters the light, and the like. Then, the fluctuation of the flame of the candle is simulated by changing the amount of current flowing through the LED chip, rotating the optical member by driving a motor, or making the apex of the optical member move regularly or irregularly. It can be done.

  Patent Document 2 describes a LED lighting device for a lantern that diffuses the direct light of the LED in a conventional candle lantern so that the inside of the lantern becomes evenly bright.

  Patent Document 3 describes a method of illuminating a god or other religious object (god and Buddhist ware) with LED light emission, and includes an electronic circuit for generating an LED drive signal, and a ROM in which data is written. Describes a configuration for obtaining fluctuation light emission based on data read out from.

  Patent Document 4 describes that a translucent or transparent enveloping body is provided asymmetrically with respect to the rotation axis to obtain a fluctuation light-emitting lamp, and describes that the LED is rotated on the rotation axis. Yes.

However, in the above technique, the fluctuation operation of the flame using LED (engineering member, enveloping body, etc.) is unnatural, the device is complicated, and there are many troubles. There was a problem.
Therefore, there has been a demand for an optical ornament using LEDs that has few failures and no problem in cost.

  In addition, “lighting fixtures from the old days” imitated by modern optical ornaments are limited to ordinary candles, lanterns, lanterns, and gods and Buddhist fixtures. )
