Abstract

The utility model designs a LED calligraphy and painting imitating device comprising a housing (1), a LED array circuit board (7) is arranged inside the housing (1), parallel connection is applied between LEDs on the LED array circuit board (7), the LED array circuit board (7) is connected with a supply hub (3) through a power switch (4), the supply hub (3) is arranged outside the housing (1) and is connected with a power source (8), and a top of the housing (1) is provided with a ground glass (2). The LED calligraphy and painting imitating device employs LEDs as light source, so calligraphies of templates can be clearly seen no matter a thin paper or a thick paper is used when people imitate the calligraphy and painting, and the device greatly facilitates calligraphy and painting learners to imitate. The LED calligraphy and painting imitating device is simple in structure, can be processed to a very thin device, and the device has advantages of easy usage and low cost.

Description

An LED calligraphy and painting copying device

technical field

The utility model relates to calligraphy and painting copying equipment, in particular to an LED copying and learning device for painting and calligraphy.

Background technique

With the development of computers, many people like to use computers to type, but the handwriting function is gradually degraded. In order to inherit and carry forward the calligraphy and painting traditions of our Chinese nation, copying writing and painting booklets on the market, as well as concave-shaped calligraphy boards, etc., they are all There is a fatal problem that the handwriting of the template cannot be seen clearly, and the paper used for copying must be special thin paper, and the handwriting of the template cannot be seen clearly on thicker paper.

Utility model content

The purpose of the utility model is to provide an LED calligraphy and painting copying device, which can clearly see the handwriting of the template no matter it is thin paper or thick paper when copying and painting, which is very beneficial for those who learn to copy and paint. Moreover, the structure is simple and the cost is low.

The utility model provides an LED copying device for calligraphy and painting, which comprises a shell, and an LED array circuit board is arranged inside the shell. The jack is arranged on the outside of the shell, the power jack is connected to the power supply, and frosted glass is arranged on the top of the shell.

A potentiometer can be connected in series between the LED array circuit board and the power supply circuit to control the brightness and safety of the LEDs.

The bottom of the shell can be provided with rubber foot pads.

The frosted glass can be replaced by frosted plexiglass or transparent plastic.

When in use, place a paper calligraphy and painting copy sample on the frosted glass, place a thin transparent film on the copy sample, and then place a blank paper on the transparent film, and then you can start copying practice. Copying can be repeated as long as the paper is changed. Continuous use for three months will significantly improve the calligraphy and painting ability of the imitator.

Advantages and effects of the utility model compared with the prior art:

The utility model LED painting and calligraphy copying device adopts LED as light source, and people can clearly see the handwriting of the model no matter it is thin paper or thick paper when copying and painting, which is very beneficial for those who learn to copy and paint. In addition, the LED calligraphy and painting copying device has a simple structure, can be processed into a very thin device, is convenient to use, and has a low cost.

Utilizing the LED painting and calligraphy copying device to practice writing and drawing is suitable for primary school students, middle school students and adults, and the ability of writing and drawing can be significantly improved in a short period of time.
