Abstract:
A light string, comprising a light bulb. The light bulb comprises a cap (100) and a globe (200); the globe (200) is connected to the cap (100); the inner wall of the cap (100) is provided with a first flange (110) and a second flange (120); a first abutting surface (210) and a second abutting surface (220) are formed on the outer wall of the globe (200); the first flange (110) abuts against the first abutting surface (210), and the second flange (120) abuts against the second abutting surface (220); the first abutting surface (210) is a tapered surface; the diameter of the position of the globe (200) corresponding to the first abutting surface (210) is gradually reduced in a direction close to the cap (100); the included angle between the first abutting surface (210) and the second abutting surface (220) is an obtuse angle. When the globe (200) is gradually screwed into the cap (100), the contact between the first abutting surface (210) of the globe (200) and the first flange (110) becomes tight gradually; the deeper the globe (200) is screwed in, the more tightly the first flange (110) and the second flange (120) are connected to the outer wall of the globe (200).
