A light bulb apparatus has a plurality of LED modules, a substrate, a driver circuit board, a plastic piece, a radiator and a lamp cap. The substrate has aluminum material for mounting the plurality of LED modules, a first connection end and a second connection end. The first connection end and the second connection end are electrically connected to the plurality of LED modules. The plastic piece with a guiding groove is used for inserting the driver circuit board. The radiator has a top plate and a side wall. The substrate is fixed on the top plate, and the side wall are connected to the plastic piece.

Light bulb apparatus

A light bulb apparatus has a bulb shell, LED modules, a light source plate, an inner tube and an outer cup. The light source plate has a substrate plate. The substrate plate and the inner tube are made of heat dissipation material like metal material. There is a pressing portion of a lateral side of the substrate plate pressing against an inner side of the inner tube part and there is a spacing portion of the lateral side of the substrate plate not engaging the inner side of the inner tube. The outer cup part has top part and a bottom part. The inner cup is placed inside the top part of the outer cup and pressing against the outer cup.

A method of installing a light emitting diode light bar into a bulb is provided. Place the light bar module into the light bulb shell. The light bar module has a plurality of light emitting diode light bars and an expansion structure. The expansion structure is not expanded and is disposed among multiple light emitting diode light bars. Each light emitting diode light bar has a certain degree of flexibility. Expanding the expansion structure then, therefore multiple light emitting diode light bars are individually bent and deformed toward the bulb shell direction. Next, remove the expansion module and install other components of the bulb.

A LED filament light has a bulb shell, a base portion, a filament module, a top spreading structure, a bottom spreading structure, a lamp cap and a driving piece. The filament module is placed in the containing space formed by the bulb shell and base portion. The filament module is composed of a plurality of filaments. The top of the plurality of filaments connects to the top spreading structure. The bottom spreading structure extends from the base portion, the bottom of the plurality of filaments connect to the bottom spreading structure. The top spreading structure is supported only by the plurality of filaments. The driving piece is placed in the lamp cap to provide electric power required for the plurality of filaments.
