Abstract: Disclosed is a filament support and a lamp with the filament support. The filament support may include a main rod, a plurality of branch rods and a plurality of support members. The plurality of branch rods are all installed on the main rod; the support members are arranged at ends of at least some of the branch rods, both ends of the support member are curved or bent towards a same side, resulting in that the support member surrounds to form a penetrating zone, and an opening for communicating the penetrating zone is formed between both ends of the support member. Both ends of the support member are curved or bent towards a same side, resulting in that the support member surrounds to form a penetrating zone, and an opening for communicating the penetrating zone is formed between both ends of the support member.

Abstract: A lamp and a lamp string are disclosed. According to the lamp base and the lampshade of the disclosure, the lampshade is connected with the lamp base, an inner wall of the lamp base is provided with a first flange and a second flange, an outer wall of the lampshade is formed with a first abutting surface and a second abutting surface, the first flange abuts against the first abutting surface, and the second flange abuts against the second abutting surface. The first abutting surface is a conical surface, a diameter of the lampshade at a position corresponding to the first abutting surface gradually decreases along a direction towards the lamp base, and an included angle between the first abutting surface and the second abutting surface is an obtuse angle.

Abstract: A ceiling lamp is disclosed including a first lamp, a second lamp, and an angle adjusting and locking device. The first lamp and the second lamp are arranged at an interval, and the second lamp and the first lamp are rotatable with respect to each other. The angle adjusting and locking device is connected with the first lamp and the second lamp, and the angle adjusting and locking device is configured for locking the first lamp and the second lamp after they are rotated with respect to each other.

Abstract: A discrete component linear circuit of a line is provided, including a switch S1, a fuse F1, a varistor MOV1, a rectifier DB1, a triode Q1 to a triode Q6, and a resistor R1 to a resistor R6, wherein an input end of the switch S1 is connected to an input end L of a power supply for input, and an output end of the switch S1 is connected to an input end of the fuse F1. When an input voltage increases, a current increases, and resistance values of a thermistor T1, a thermistor T2 and a thermistor T3 increase due to temperature rise. The resistance increases synchronously when the voltage increases, so that the current is maintained in a relatively stable interval. Therefore, the voltage bearing capacity when an LED lamp works is increased, and more LED lamps may be used in parallel.
