Abstract
A lighting bulb is provided. The lighting bulb has a housing, a lighting unit and an electrical connector. The housing is configured for accommodating a circuit board and a heat-dissipating sealant is filled in the housing. The lighting unit is coupled to the circuit board for emitting the light and the electrical connector is configured for providing power to the circuit board and the lighting unit. A protruding member disposed on the inner surface of the housing and the circuit board form a mechanical interference against the floating force of the heat-dissipating sealant to the circuit board.
