An LED
bulb lamp comprises a
lamp shell, a lamp head connected with the
lamp shell, a core column, conductive supports, LED filaments and
cantilever arms, wherein the core column comprises a core column bottom and a core column top which are opposite to each other, the core column bottom is connected with the lamp head, and the conductive supports are connected with the core column top. Each
LED filament comprises a filament body and filament electrodes, wherein the filament electrodes are located at the two opposite ends of the filament body, the two filament electrodes are connected with the two conductive supports, the core column is surrounded by the filament bodies, one end of each
cantilever arm is connected with the core column, and the other end of each
cantilever arm is connected with the corresponding filament body. In the height direction, the distance from the bottom of the
lamp shell to the top end of the lamp shell is H, a first
height difference ranging from 0 to 1 / 10H exists between every two corresponding filament electrodes, each filament body is bent up and down and has a highest point and a lowest point, a second
height difference exists between the highest point and the lowest point, the first
height difference is smaller than the second height difference, and the second height difference ranges from 2 / 10H to 4 / 10H. The LED
bulb lamp is good in glowing effect, easy to make and large in light emergent angle.
