Provided is an LED bulb (100), comprising: a lamp cap (1), a lamp shade (2), an LED filament (3) arranged inside the lamp shade (2), and a power source drive module converting an alternate current into a direct current, wherein the LED filament (3) is electrically connected to the power source drive module; and the LED filament (3) comprises a substrate and several LED chips arranged on the substrate. There is no need for the LED bulb (100) to have a radiator installed, so that the lamp shade (2) can wrap around the LED filament (3) at a wider angle, and therefore, the light-emitting angle of the LED bulb (100) can reach 360°. In addition, compared with an incandescent lamp, the LED bulb saves more energy, is more environmentally friendly and has a longer service life by using the LED filament (3) as a light-emitting light source. |
