The present invention relates to a rotatable LED module string, and more particularly, rotatably installing a housing connected to a power supply cord to which power is supplied, and detachably installing an LED block to the housing, thereby generating light from the LED. It selectively relates to the direction of irradiation of the LED module as well as a rotating LED module that can be replaced easily.

In order to improve visibility in the room or at night, a lighting device is used, and one or two or more lighting devices are generally installed and used.

On the other hand, in places such as companies and shops, signs are installed as signs that are installed to easily attract the attention of the customers who are being sold, and there are various kinds of signs depending on the installation location, internal structure, and advertisement contents. As the business environment becomes more complex and fierce, it is diversifying day by day.

On the other hand, the type of signboard is classified into an outer sign attached to the outer wall of the building and an inner sign attached to the wall surface of the room according to the installation position thereof.

The external signage is installed on the upper side of the entrance or the outer wall of the building to inform others of the store's name or phone number and handling items, so as to obtain the effect of the advertisement, its size is large and accordingly heavy.

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.

A channel sign is a frame (bending, cutting) attached to a wall surface according to various letters or patterns. Recently, a channel sign is 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 signs using fluorescent or neon lamps have a short repair cycle because the lifetime of the fluorescent or neon lamps is relatively short, so that economic and time losses are not small, and heat is generated and power consumption is relatively low. Because of this size, there was a problem that takes a lot of maintenance costs.

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

In particular, the LED is widely used as an internal lighting device of the channel signboard as well as indoor and outdoor lighting, hereinafter will be described as an example of the LED embedded in the channel signboard.

Therefore, in the related art, after cutting the substrate 301 so that the LED module 300 is embedded in the channel board, a separate power line (not shown) is connected to the side of the substrate 301.

On the other hand, since most of the channel board is formed in a bent or arc shape (including a circular shape), the cutting of the substrate 301 and the connection of the power line to the substrate 301 to be embedded in the channel board must be repeatedly performed. There was a problem.

When the power line is connected to the substrate 301 as described above, when the channel signboard is installed outside, the rainwater flows into the channel signboard in case of bad weather, and the LED lamp 302 is caused by the short circuit. Damage, of course, there was a problem such as a fire occurs in severe cases.

In addition, since the conventional LED lamp 302 is maintained in a fixed state on the front of the substrate 301, since the irradiation direction of the light generated from the LED lamp 302 are all the same, there is a limit that can be produced by using light There was.

Therefore, the conventional general lighting device and the signage lighting device has been a problem of a lot of power consumption and heat generation, there are various problems such as short life and require attention to handling.
