The invention is installed in the luminaire, such as the illumination of the automotive interior and exterior lighting, or furniture will be the light sources to illuminate the light, it is possible to produce a compact by a simple structure that is formed to the terminal is exposed at both sides of a substrate having an LED element small size the installation of the lights will be on for the lighting bulbs suitable fuse type.
The present invention to solve this objective; As for a lighting bulb, it has a one side open to the interior space, and the first fitting portion 120, the base 100, protruding from each side; The covers the open side of the base 100, provided with the LED element 210 to the exposed surface substrate 200, and; Sikimyeo cover the exposed surface of the substrate (200) emitting light of the LED element 210 to the outside, and on both sides of the second fitting portion 320 is formed projecting lens 300, respectively; The first and second doedoe each fitted fixed to the outer periphery of the fitting portion (120 320), the board 200 while electrically connecting to the pair terminal 400 for supplying external power to the substrate 200 and the lens (300 ), the refracting part (500) for scattering by refracting the light from the LED element 210 in the direction in which the plurality of circular protrusions 510 are formed to be extended to the same center, with the circular projection 510 in the inside of the It is configured to include.
