Abstract (en)
A LED bulb apparatus has a bulb shell (8801), a head cap (8802), a driver circuit (8803) and at least one light strip (8804) having multiple LED modules (8815) mounted on a substrate (8812). The bulb shell (8801) has a light passing shell (8805) and a bottom portion (8806). The head cap (8802) has a neck portion (8807), a first electrode (8808) and a second electrode (8809). The neck portion (8807) of the head cap (8802) is connected to the bottom portion (8806) of the bulb shell (8801) forming a container space (8811). A fluorescent layer (8816) covers the multiple LED modules (8815). The driving current is transmitted via at least one of the top end (8813) and the bottom end (8814) of the light strip (8804) to the LED modules (8815). The substrate (8812) has a light transmittance less than 50%.
