An LED bulb comprises a lamp holder (1), a core column (10), and a glass bulb (2). The core column (10) and the glass bulb (2) form a sealed body. The lamp holder (1) and the glass bulb (2) are connected by using glue to form the LED bulb. A luminous body is disposed below the core column (10) in a fitting mode. The luminous body consists of a substrate (7) and an LED (8). An LED driving plate (6) is welded above the substrate (7). The LED driving plate (6) is connected to a steel needle (4) in the middle of the core column (10) by using a chuck (5). Two wires (3) led out from the LED driving plate (6) are welded with one ends of two static wires (11) on the core column (10), and the other ends of the two static wires (11) are welded with the lamp holder (1). By means of a structure of making a bulb by using an LED lamp, light can be emitted in an omnibearing mode, energy consumption is reduced, the luminous efficiency is enhanced, and the cost is reduced. |
