Description

Chandelier using LED {CHANDELIER USING A LED}

The present invention relates to a chandelier using an LED, which does not need to provide an LED device module having a predetermined density to provide a predetermined illuminance, and can emit light with a warm feeling while using a white LED. The present invention relates to a chandelier using LEDs that can provide lighting of various colors and various directions.

In general, the chandelier is installed on the ceiling of the room is used to beautifully illuminate the room, especially the appearance is luxurious and colorful, widely used as an interior member for interior decoration.

Conventional chandeliers not only consume a lot of power, but also require frequent replacement of the bulb, but since the chandelier is suspended from the ceiling, the replacement of the bulb is not easy, and there is a problem that it is not easy to repair in case of other component failures, and provides various colors. There is a problem that cannot be done.

Therefore, the application of LED devices with low power consumption, semi-permanent, and capable of outputting light of various colors to chandeliers has been studied.

By the way, the chandelier has been used to reflect the light from the LED module by using a LED module equipped with a PCB substrate of a predetermined density LED in order to provide a predetermined illuminance.

However, due to the structural characteristics of the LED device, since light has a straightness, it is difficult to perform a constant lighting as a whole in a room where lighting is required.In the case of using a white LED for high illumination, it is not white light close to natural light due to the nature of a white LED. It produces pseudo white light close to blue light, which increases eye fatigue and is not suitable for indoor lighting.

For this reason, in the case of LED lighting, if you want to perform bright lighting (high illumination), the intensity of light output of each LED device is lowered, while the density of the arrangement on the illumination surface of the LED device is increased. There is a risk of fire because a large amount of heat is released from the devices.

In addition, there is a problem that a separate heat dissipation means is required to dissipate such heat.

The present invention has been made to solve the above problems, an object of the present invention is to produce a predetermined white light of a predetermined illuminance and warm without the configuration of the LED module, and to allow the light to diffuse in all directions for a certain space It may be, and may not be provided with a separate heat dissipation means, to provide a chandelier using an LED that is beautiful in appearance and can produce a variety of colors, lighting in various directions.

The chandelier using an LED according to an embodiment of the present invention for achieving the above object is connected in series with a frame composed of at least one stage and a converter for converting AC current into DC current along the frame. A cable, a plurality of branch cables branched from the main cable and arranged at predetermined intervals, at least one LED element connected to an end of the branch cable, and a filament for reflecting light of the at least one LED element An LED lamp comprising a spherical body portion for receiving a spiral and a plurality of transparent receiving members having a neck portion connected from the body portion, and a suspension member having one end fastened to the neck portion of the receiving member and the other end hanging on the frame. It is characterized by.

According to one embodiment of the present invention, LED elements may be received in parallel in a plurality of transparent receiving members with respect to a frame composed of at least one stage, thereby providing a predetermined illuminance without configuring an LED module.

According to an embodiment of the present invention, since the plurality of LED elements are flexible and are suspended on branch cables having different lengths, the LED elements can reflect light in all directions, and the filament spirals provided in the transparent receiving member are used to By diffusely reflecting light, it can provide light close to natural light and at the same time, it can dissipate heat generated from the LED device.

Various colors of each of the plurality of LED elements may be provided to provide various lights.

According to an embodiment of the present invention, it is possible to provide a predetermined illuminance without configuring the LED module, to allow the light to diffuse in all directions for a predetermined space, and may not be provided with a separate heat dissipation means, appearance It is possible to provide chandeliers using LEDs that can produce beautiful, diverse colors and various directions of illumination.
