[0001] EDGE TYPE LED ILLUMINATOR [0002]

The present invention relates to an indoor lighting system, and more particularly, to an indoor lighting system capable of easily mounting a structure itself on a ceiling, facilitating removal and attachment of an LED unit, Type LED lighting fixture.

In general, a lighting lamp converts electric energy into light energy, so that it can identify an object even in a dark place, and recently, it is widely used to produce an interior decoration or a cozy atmosphere.

Normally, the light source used for illumination is manufactured in various forms such as incandescent lamps, fluorescent lamps, halogen lamps, and three-wavelength lamps. Since gas is injected into a vacuum glass tube, Or cause air pollution.

In addition, incandescent lamps are inexpensive to manufacture, but when energy is converted into electric energy, much heat is generated and the use of fluorescent lamps is limited. In the case of fluorescent lamps, energy conversion efficiency is higher than incandescent lamps, There is a problem that it is consumed and its life is short.

In order to solve these problems, recently, a light emitting diode (LED) capable of obtaining a high luminance with a semi-permanent lifetime and low power has been actively developed, and has advantages such as a high processing speed of an LED device and low power consumption Of course, it is environmentally friendly, but it is also attracting attention as a next-generation strategic product because of its high energy saving effect.

The ELD device consists of p-type and n-type semiconductor junctions. When a voltage is applied, the energy corresponding to the band gap of the semiconductor is emitted in the form of light by the combination of electrons and holes As a kind of optoelectronic device, various color LED devices have recently been developed to enable the display of natural color, and it is applicable to a variety of applications such as large outdoor signboards, traffic lights, automobile instrument panels, home appliances, neon signboards, medical equipment, .

In addition, the illumination lamp using the LED device is attracting attention as a lighting apparatus because it has a low power consumption of about 20% to 40% and a semi-permanent life span of 50,000 hours or more and environment-friendly characteristics compared to conventional incandescent lamps or fluorescent lamps. In general, it can be classified into a direct type in which light is directly irradiated according to an arrangement method of an LED element and an edge type in which a light guide plate is used.

With respect to the above-mentioned LED lighting apparatus, Korean Patent Registration No. 0961236 discloses a lighting system having various shapes and shapes, a unit lighting system in which an LED module can be appropriately arranged in such a frame, In addition, in the case of the registered patent No. 1369422, the circuit board is fixed so as to be closely attached to the bottom of the heat radiating frame without the fastening member such as a bolt or a screw, thereby improving the heat conduction performance A light scattering loss can be prevented, and the illuminance can be improved.

Discloses a technique for providing a highly efficient illumination by reducing the overall thickness of the illumination lamp and effectively reflecting the light by constituting the illumination light on the mutually corresponding positions so as to reflect the light according to the light source of the LED illumination.

However, in the conventional lighting apparatuses as described above, since it is difficult to radiate light with a uniform illuminance as a whole, the size of the product is limited, and one or more circuit boards must be installed to match the size of the lighting apparatus There is an economical loss, and there is a problem that the heat generation structure is very weak.

In addition, since the fabrication process of the LED lighting apparatus is generally complicated, the assembling work efficiency is not efficient. Therefore, the manufacturing cost is increased. In order to cool the high heat generated from the LED module, But it fails to exhibit a sufficient effect, causing failure of the LED module due to overheating, shortening the life span.
