In general, a halogen lamp, a fluorescent lamp, or a three-wavelength lamp is used as a luminaire. However, they consume more power and have a shorter lifespan than light emitting diodes. Therefore, the cost of replacing them is continuously generated. Especially in the case of halogen lamps, heat is generated and ultraviolet rays are generated. There is a concern.

The light emitting diode has a high photoelectric conversion efficiency, so the power consumption is very low, less than 2W for a single device, and because it is not light emitting due to thermal discharge, there is no need for preheating time, so the lighting and lighting speed are fast. Is coming out a lot, and is emerging as a technology to replace most of the lighting fixtures in the future.

Such a light emitting diode, or LED, is a photoelectric conversion semiconductor device having a structure in which an N-type semiconductor in which a plurality of carriers are electrons and a P-type semiconductor in which a plurality of external carriers are holes are bonded to each other. A semiconductor device using emission light generated when electrons and holes injected into a junction recombine.

In particular, the light emitting diode can be driven at a relatively low voltage, but has a low heat generation and a long life due to high energy efficiency, and has been developed to provide white light with high luminance, which has been difficult to implement in the past. The application is expanding.

For example, as a luminaire using the light emitting diode, Patent No. 10-0348504 discloses an LED luminaire using an LED and a diffusion sheet, and Patent Publication No. 10-2004-0037523 discloses a luminaire using an LED as an indoor or outdoor interior device. Patent Application Publication No. 20-0369140 discloses a bulb-type LED bulb in which a constant current circuit is incorporated as an interior lighting and decorative lamp.

However, the conventional luminaire using a light emitting diode is most of the open type without a case for protecting the light emitting diode (LED), or the method of inserting the light emitting diode in a transparent tube tube is mostly used.

Therefore, in the case of the open type without the protective case of the light emitting diode, there is a problem that the light emitting diode and the substrate coupled thereto may be easily broken or damaged by external force.

In addition, in the case of inserting the light emitting diode into the transparent tube tube, since the transparent tube tube has a circular shape, it is difficult to install on a flat surface and is not sensitive to heat because it is not a structure for dissipating heat generated by the substrate.
