Abstract: An LED filament, comprising a plurality of light-emitting chips, a metal electrical terminal, a fluorescent glue, an insulating substrate and an electrically and magnetically conductive connector. The plurality of light-emitting chips are connected in series, and encapsulated and fixed on a surface of the insulating substrate by the fluorescent glue, one face of the electrically and magnetically conductive connector is fitted on the other surface of the insulating substrate, the metal electrical terminal is electrically connected to a light-emitting chip at one end of the insulating substrate. Also provided is an LED filament light, comprising a plurality of LED filaments and a permanent magnet. The LED filaments are magnetically and movably connected by means of magnetic attraction via the permanent magnet, and are capable of automatic sliding adjustment during thermal expansion and elongation.

Abstract: An LED light including: a light-emitting bulb including a shell; a lamp holder connected to the light-emitting bulb and including external thread; a power driver disposed in the lamp holder; a stem including a wire; and a light-emitting component. The stem and the light-emitting component are disposed in the shell. One end of the stem is connected to the power driver, and the other end of the stem is connected to the light-emitting component. The light-emitting component includes at least two bar-type LED filaments. The at least two bar-type LED filaments are connected in series or in a combination of series and parallel connections. The at least two bar-type LED filaments are connected to the power driver through the wire of the stem.

Abstract: A parallel-connected LED illuminant, including: a parallel-connected bracket, LED light emitting unit groups, and fluorescent powder layers. The parallel-connected bracket includes two or more than two linear substrate monomers. The linear substrate monomers are disposed in parallel. Each of the LED light emitting unit groups is disposed in the straight line on each of the linear substrate monomers along the long axis thereof. The LED illuminant is connected in series with electrode pins disposed at two ends of the parallel-connected bracket. The surface of each linear substrate monomer where each LED light emitting unit group is disposed is coated with each of the fluorescent powder layers.
