Description

TECHNICAL FIELD

[0001] The utility model mainly relates to a kind of LED bulb lamp structure. BACKGROUND

[0002] In recent years, a kind of LED filament that can make LED light source similar to traditional tungsten filament bulb emit light and achieve full-angle illumination is increasingly valued by the industry. The manufacture of this LED filament (i.e. lampwick) is to fix a plurality of LED chips in series on a narrow and slender substrate, then wrap the entire glass substrate with silicone containing fluorescent powder, and then complete the electrical connection. However, since the existing filament substrate only has LED chips on one side, and LED light has the characteristics of point light source and directionality, in order to completely replace traditional incandescent lamps and achieve full light distribution, multiple filaments must be arranged in one bulb. These LED filaments are fixed on the stem in series or parallel or series-parallel combination, driven by an LED driving power supply, which is placed in a plastic housing for connecting the bulb shell and the lamp cap. Although the LED filament has wide-angle illumination, the light directed to the position of the lamp cap is wasted since it is not transparent. Therefore, improvements have been made to the LED bulb lamp structure to make full use of the light emitted by the lampwick. SUMMARY
