The present invention relates to a bulb-type lamp with a double-curved structure and, more specifically, to a bulb-type lamp with a double-curved structure capable of maximizing the heat radiation efficiency by, during the manufacturing of a bulb-type lamp, making the lamp body of the lamp in one body without joints using a double-curved structure and transferring the heat generated by an LED module which emits light to the curved structure, which is a heat radiation body, of the lamp body. The present invention includes: an LED module which includes a plurality of LEDs and emits a certain amount of light; a lamp body which is made from an aluminum board without joints in one body, of which the outer shape is composed of a lamp outer body lateral surface part to form the conical outer part, a lamp outer body small diameter part to form the small diameter part of the conical shape, and a lamp outer body large diameter part to form the large diameter part of the conical shape, of which the inner shape is made by an LED module mounting part to form the cylindrical top part, and which is fixed in a way that the bottom surface of an LED PCB is in surface-contact with the LED module mounting part; a spreading cover which is combined to one side of the lamp body and spreads the light emitted from the LED PCB; and a base which is attached to the lamp outer body small diameter part while being insulated and is connected to an external power to supply power to the LED PCB. |
