An LED filament and an LED light bulb applying the same are provided. The LED filament includes a at least one LED section, wherein the at least one LED section comprises at least two LED chips electrically connected to each other through a first wire, and at least two conductive electrodes, wherein each of the at least two conductive electrodes is electrically connected to corresponding one of the at least one LED section; and a light conversion layer, covering the at least one LED section and a portion of each of the at least two conductive electrodes, a portion of the first wire is exposed outside the light conversion layer.

The present disclosure discloses an assembled visual machete, including a first machete body and a second machete body; the first machete body and the second machete body are integrally assembled through a detachable bridging part; light emitting diode (LED) light strips are arranged on the first machete body and the second machete body; a control board and a battery are arranged in the bridging part; and the battery and the LED light strips are electrically connected to the control board. Therefore, when it is necessary to package and transport the entire assembled visual machete, the first machete body and the second machete body at both ends of the bridging part can be directly removed, and the bridging part, the first machete body and the second machete body in a detached state are placed in a package.

A lighting device with improved luminous performance is provided, which includes a first light path, a second light path and a plurality of first light sources and second light sources. The first light path includes a plurality of first bending portions and second bending portions arranged in staggered arrangement. Each first bending portion and each second ending portion protrude from one side and the other side of a first reference line respectively. The first light sources are distributed over the second bending portions. The second light path is connected to the first light path in parallel, and includes a plurality of third bending portions and fourth bending portions arranged in the staggered arrangement. Each third bending portion and each fourth bending portion protrude from one side and the other side of a second reference line respectively. The second light sources are distributed over the third bending portions.

The one or more LED filaments (110) are arranged to form an inner space. At least one of the one or more LED filaments (110) is arranged as a LiFi transmitter. The LiFi device (100) further comprises a light sensor (120) arranged within the inner space. The light sensor (120) is arranged as a LiFi receiver. The LiFi device further comprises an envelope arranged to envelope the one or more LED filaments (110) and the light sensor (120). The one or more LED filaments (110) are further arranged such that the LED filament light is directed towards the envelope.
