If the Fresnel lens method does not have a curved top surface, it is possible to set various light diffusion angles, and thus it is desirable to have an advantage of designing an efficient and simple shape.

The basic configuration using the drawings as described above will be described in detail again.

In general, a conventional light bulb using a filament is composed of a lens that is a socket and a body portion is mounted in a closed space portion, the filament is heated when the power is applied, and accordingly the temperature radiation is made to emit light (發光). Therefore, it takes a predetermined time to perform the temperature radiation when the power is applied, there is a problem that the response is inferior, the life of the lamp is reduced by maintaining the high temperature state of the closed space by the heat generated from the lamp, Due to frequent parts replacement, there was a problem that the maintenance cost increased.

An electric device is installed; A lead wire (2, 71) exiting the electrical device; The LED light emitting device, the electric device, and the non-conductor socket part 11 are formed into a body part 5 which is solidified in one body. At this time, the solidifying material includes an epoxy dome lens shown in the LED structure of FIG. It is preferable to use an epoxy such as an epoxy dome lens, and the reason why the socket portion 11 is a non-electrically conductive non-conductor is that the body portion is solidified by integrating a substance such as epoxy, which is a non-conductive material; Fixing the body portion (5) to the conductor socket (6) and the conductor socket base (9); And an integrated super bright LED bulb and a method of manufacturing the lead wires (2, 71) connected to the lower end (91) of the conductor socket base (9) and the side end (7) of the conductor socket. do.
