Abstract: A method for creating a lighting effect by two segments on one filament, comprising a first fluorescent rubber strip and a second fluorescent rubber strip installed by butting, and a chip support arranged between the first fluorescent rubber strip and the second fluorescent rubber strip; a plurality of LED chips are evenly arranged on the chip support, and the LED chips are in positive and negative parallel connection with each other by conducting wires; and metal wire lugs are installed at both ends of the chip support. Compared with the prior art, the method can be applied to some special application scenarios, such as a light which can illuminate without a drive. By arranging the LED chips in positive and negative inverse parallel connection on the same light-emitting filament, light emitting by two or more segments on one filament or light emitting at intervals is realized, so that non-polar light emitting of the filament is realized.
