However, the LED has a disadvantage that the overall efficiency is lowered because the LED is used.

In addition, as the conventional LED light source, there is a light emitting diode (LED) which is radially arranged inside as disclosed in Korean Patent Publication No. 26300 (published on March 23, 2006) or registered patent No. 897919 (published on May 18, 2009) Emitting diodes are stacked in multiple layers or radially arranged LEDs are formed as a single layer and convex diffusion plates are provided on the outside, and an integral cap having a transparent outer side of the light source is provided. However, such an integral type of transparent In particular, the cap of the registered patent No. 897919 has a plurality of mountain-shaped protrusions on its outer side, which is called a fresnel lens. In the case of such a Fresnel lens, it is difficult to mold because of the need to form elongated mountain-shaped projections on the outer surface in the circumferential direction, The cost is further increased, and in addition, the molding accuracy is lowered at the time of manufacturing, which causes the efficiency of light condensation to be lowered. As a result, there has been a problem in that the response of the product is lowered.
