Abstract

See full text

An LED light bulb includes a bulb shell, a bulb base, two conductive supports, a stem, and an LED filament. The bulb base is connected with the bulb shell. The two conductive supports are disposed in the bulb shell. The stem extends from the bulb base to inside of the bulb shell. The LED filament includes a plurality of LED chips and two conductive electrodes. The LED chips are arranged in an array along an elongated direction of the LED filament. The two conductive electrodes are respectively disposed at two ends of the LED filament and connected to the LED chips. The two conductive electrodes are respectively connected to the two conductive supports. The LED filament is curled to satisfy symmetry characteristics. Surface roughness of segments of a portion of the LED filament in different quadrants in a top view or in a side view is in line symmetry or in point symmetry.
