LED filament and LED light bulb

An LED light bulb, comprising:

• a lamp housing with a central axis;
• a bulb base connected to the lamp housing;
• a stem disposed in the lamp housing along the central axis of the lamp housing;
• two conductive supports disposed in the lamp housing, the two conductive supports having opposite polarities;
• a driving circuit disposed in the bulb base and electrically connected to the two conductive supports;
• and
• a flexible LED filament disposed in the lamp housing and electrically connected to the two conductive supports, the flexible LED filament comprising:
• an LED section comprising a plurality of LED chips connected in series and a light conversion layer wrapping the plurality of LED chips;
• a first conductive electrode disposed at one of two ends of the LED section and electrically connected to the plurality of LED chips and one of the two conductive supports, wherein a portion of the first conductive electrode is wrapped by the light conversion layer;
• a second conductive electrode disposed at the other one of the two ends of the LED section and electrically connected to the plurality of LED chips and the other one of the two conductive supports, wherein a portion of the second conductive electrode is wrapped by the light conversion layer;
• a conductive portion electrically connected between two adjacent LED chips, the conductive portion comprising two end portions;
• and
• a first solder layer disposed on one end portion of the conductive portion,
• wherein an LED chip among the plurality of LED chips has an electrical connecting portion, the one end portion of the conductive portion is connected to the electrical connecting portion and the first solder layer is disposed on the end portion of the conductive portion, and the end portion of the conductive portion is sandwiched between the electrical connecting portion of the LED chip and the first solder layer.
