The present invention relates to a rotatable LED module string, and more particularly, rotatably installing a housing connected to a power cord to which power is supplied, and to irradiate light generated from an LED by magnetically attaching an LED block to the housing. The present invention relates to a rotating LED module string, in which the direction of the LED block can be easily changed as well as the direction can be selectively adjusted.

Lighting devices are used to improve visibility in the room or at night, and these lighting devices are generally provided with one or more than two.

On the other hand, the signboards are installed in order to easily attract the attention of the sales place or sales content of the company or shop, etc., and the signboards have various kinds according to the installation place, the internal structure, the advertisement contents, As the business environment becomes more complex and intense, the situation is diversifying.

The kinds of signboards are classified into exterior signs attached to the outer wall of the building and inner signs attached to the wall of the room, depending on the installation position thereof.

The exterior signboard is installed on the upper side of the doorway or on the outer wall of the building to inform others of the store's name, phone number, and handling items, so as to obtain the effect of the advertisement. .

The internal sign is attached to the interior wall of the store and is installed for the purpose of advertising the photographs, trade names, and various pictures and texts of the products.

These signs are divided into panel signs and channel signs according to their form.

Panel signage is to install the advertisement in the form of a plate inside the frame consisting of a square or a circle.

In addition, the channel signboard is manufactured (bending, cutting) and attached to the wall surface according to various letters or patterns, and in recent years, the channel signboard has been widely used.

In addition, the signboard is based on differentiated identification or visibility, and an illumination device that enables the consumer to easily recognize the contents even at night is an essential element.

The lighting device of such a signboard is largely classified into an external lighting device and an internal lighting device, and a representative example of the lighting device used as an internal lighting device so far may include a fluorescent lamp and a neon lamp.

However, the above interior lighting panel using fluorescent or neon lamps has a short repair cycle because the life of fluorescent or neon lamps is relatively short, so that economic and time losses are not small, and heat is generated and relatively power is generated. There was a problem that the maintenance costs are high because of the large consumption.

Accordingly, recently developed is an internal lighting sign that uses an LED lamp (hereinafter referred to as 'LED') as a backlight.
