Description

Detachable LED lighting device {LED LIGHTING APPARATUS WITH DETACHABLE STRUCTURE}

The present invention relates to a detachable LED lighting device, and more specifically, by improving the fastening structure so that a separate wiring is not required between the main body and the base plate, connecting and disconnecting the power source in the process of combining and separating the main body from the base plate. It relates to a removable LED lighting device that can be made together.

Until now, as lighting equipment, the inside of a light bulb was vacuumed and electric current was applied to the filament to generate heat, and incandescent lamps using light emitted from the filaments and electrons emitted from the filaments of one electrode collided with mercury vapor filled in the glass tube to obtain energy. Fluorescent lamps using the phenomenon of emitting light while losing were mainly used.

Lighting equipment using incandescent and fluorescent lamps has a limitation in durability that can not be used for a long time because of high power consumption, low illumination, and short filament life.

Accordingly, in recent years, energy consumption is less than that of a conventional light source, and because of the advantage of being able to express various colors, lighting lamps using LEDs (Light Emitting Diode) are widely used as lighting devices.

The LED lighting device is most preferred as a lighting device because it can obtain high illuminance with a small electric power and its life is almost semi-permanent, and is manufactured in various forms.

The LED lighting device may be divided into a direct method and an edge method according to the light transmission method.

The direct method is an illumination method in which LEDs are arranged as much as the entire area of the luminaire and directly irradiates a light emitting surface. It has the advantage of being capable of designing with high illumination with less light loss than the edge method. There are disadvantages of high power consumption, heavy weight and thick thickness.

The edge method is a lighting method designed to uniformly project light without loss by repeating diffuse reflection and refraction through a light guide plate by placing a one-dimensional light source on the side and scanning light horizontally onto a two-dimensional light guide plate. There are advantages in that at least 144 to 160 LEDs are used, the price or power consumption is lower than that of the direct method using LEDs, the price and power consumption are low, and the thickness of the overall appearance is thinner compared to the direct method.

Most of these LED lighting devices, in order to fix the main body of the LED lighting device to a ceiling or a wall, must be coupled to a fixing device installed on the ceiling or the wall.

However, in the conventional LED lighting device as described above, since the electrical wiring for supplying power to the LED protrudes outward from the ceiling or the wall during the installation process, the electrical wiring causes inconvenience to the installation of the LED lighting device. .

In addition, even when the main body is separated from the fixed equipment due to a failure in the process of using the LED lighting device, there is a problem in that the operator must perform maintenance while paying attention to safety due to the electric wiring protruding outside.

Therefore, in the present invention, by improving the fastening structure so that no separate wiring is required between the main body and the base plate, power connection and separation are performed together in the process of combining and separating the main body from the base plate, thereby installing and maintaining the LED lighting device. I would like to suggest a way to easily perform.

In particular, the present invention allows the main body to be fixed by being coupled to the base plate, and at the same time, the electrodes formed on each of the main body and the base plate are brought into contact with each other, so that there is no separate wiring between the main body and the base plate.
