Although the shape of the LED filament lamp is consistent with that of the traditional glass-encased bulb lamp, due to the poor heat conduction and heat dissipation capabilities of the LED filament, the electrical input power has remained at about 4W and the luminous flux is about 500LM so far, which cannot greatly increase the luminous flux. The limitation of factors such as materials and manufacturing process, the price is relatively high, which affects its further promotion and use. What method should be used to design and produce LED bulbs whose shape and light intensity are consistent with those of traditional glass bulbs, and which have high input power and low cost are exactly the problems that people are exploring.
