Abstract
The invention disclosures an LED imitation filament bulb which belongs to the field of lighting appliance technologies, it solves the problem that LED imitation filament bulb produces the poor line pattern, the LED imitation filament bulb, including a glass shell, a lamp holder fixedly connected to the glass shell, and a LED lamp bead connected within the glass shell, where the LED lamp bead is electrically connected to the lamp holder; at least one imitation filament connected to the lamp holder is disposed within the glass shell; the imitation filament is transparent; the imitation filament is disposed in a bent manner; and a luminous surface of the LED lamp bead faces an end surface of the imitation filament. the LED imitation filament bulb has a luminescence effect of a traditional filament bulb; and the imitation filament bulb is more energy-saving compared with a traditional filament bulb.
