Abstract

PURPOSE:To reflect various shapes in a rainbow pattern with simple constitution by locking plural prisms at desired spots of a supporting tool to which they are attachably/detachably locked so that the shape of a numeral or a Roman letter, etc., may be formed and casting light from a specified direction so that the shape in the rainbow pattern by transmitted light may be reflected on a wall surface, etc. CONSTITUTION:This tool is constituted of plural prisms 2 and the supporting tool 3 to which the prisms 2 are attachably/detachably locked at the optional positions. By locking the respective prisms 2 at the desired spots of the supporting tool 3 and combining the plural prisms 2, the shape of the numeral or the Roman letter, etc., is formed. Then, the light is cast to the respective prisms 2 from the specified direction so as to reflect the shape of the numeral or the Roman letter, etc., in the rainbow pattern on the wall surface, etc. Thus, the numeral, the Roman letter, KATAKANA(square form of Japanese syllabary), HIRAGANA(cursive form of Japanese syllabary) or KANJI(Chinese character), etc., in the rainbow pattern by the light is reflected on the desired spot with the simple constitution.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an optical display device that can be used as a light display in various event venues, various product stores, and the like.

[Conventional technology]

Recently, displays at various event venues, shops, etc. have become more diverse and individualized. For this reason, various displays have been devised, and when installing these displays, consideration is given to the place of use, purpose, effect, etc., and displays suitable for various event venues and the like are designed. One such example is a display in which various patterns, characters, shapes of objects, etc. are drawn by combining lights of various colors.

[Problem to be solved by the invention]

However, the above-described light display using a combination of lights of various colors has the problem that the device is large-scale and the construction cost is also high. Furthermore, in the current state of displays, there is a desire for displays with a variety of different effects based on light. The present invention was developed in view of the above-mentioned circumstances, and its purpose is to simplify the structure and to make it possible to project various shapes such as numbers and letters in a rainbow pattern at desired locations. An object of the present invention is to provide an optical display device that can perform the following functions.

[Means to solve the problem]

Therefore, in order to effectively achieve the above object, the present invention has the following configuration. That is, a plurality of prisms,
It consists of a support that can detachably lock these prisms in any position, and each prism can be locked at a desired location on the support to form numbers, alphabetic letters, etc. by combining multiple prisms. The structure is such that each prism is irradiated with light from a predetermined direction, and the shapes of rainbow-patterned numbers, alphabetical letters, etc. are projected onto a wall surface or the like by the transmitted light.

[Effect]

With the above configuration, by transmitting light through the prisms arranged in the form of numbers, letters, etc. on the support, it is possible to project a rainbow pattern of desired numbers, letters, etc. on a wall surface, etc.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is an optical display device according to an embodiment of the present invention, and is composed of a plurality of prisms 2 and a support 3 that can detachably lock these prisms 2 in any position. The size and material of the prism 2 may be changed in various ways. Moreover, as a light source that passes through these prisms 2, it is preferable to use sunlight or light light of about several hundred watts. The support 3 consists of a rectangular frame 3a and support line parts 3b that can detachably lock each prism 2, and the support line parts 3b are arranged in parallel at a predetermined interval within the frame 3a. It is. Prisms 2 are arranged between each of the support line parts 3b so that desired numbers, alphabetic characters, katakana, flat names, kanji, and other various characters and simple figures can be formed by combining a plurality of prisms 2. do. Then, both ends of the long side of each prism 2 are positioned on the rear side of the support 3, a transparent plate 4 is attached to the back side of the support 3, and the transparent plate 4 and each support line part 3b each form a prism. Hold 2. Reference numeral 5 denotes support legs that can support the support tool 3 by changing its angle. By shining sunlight or a light beam of about several hundred watts onto the plurality of prisms 2 arranged on the support 3 as described above, the light A transmitted through each prism 2 becomes a spectrum and is emitted from the wall surface, etc. Rainbow-patterned numbers, English letters, katakana, flat names, kanji, and other various characters and simple shapes will be projected on the screen.

【Effect of the invention】

In this way, the present invention has a simple configuration and can project rainbow-patterned numbers, alphabetic characters, katakana, flat names, kanji, etc. in desired locations using light, making it possible to create a variety of displays with different tastes than ever before. It can be applied to many places, and its utility value is great. Therefore, it can be used as a display at various event venues, various product stores, etc., or as a light interior for the living room of each home.

Claims (1)

[Claims] (1) Consists of multiple prisms and a support that can detachably lock these prisms in any position. Each prism is locked at a desired location on the support and the combination of multiple prisms is used to create numbers and numbers. An optical display device characterized by a configuration in which the shapes of alphabetic letters, etc. are formed, and each prism is irradiated with light from a predetermined direction, so that the transmitted light projects the shapes of rainbow-patterned numbers, alphabetical letters, etc. on a wall surface, etc. .
