Embodiment
[0029] like figure 1 As shown in the present invention, a miniaturized LED filament lamp drive power supply and its assembly process, the zero wire connector N and the live wire connector L are connected to the rectifier circuit DB1 on the bridge, and the output terminal of the rectifier circuit DB1 on the bridge passes through the filter capacitor C4, the resistor After filtering, R1 is connected to the filament interface LED+ and LED- of the LED lamp, and there are parallel step-down capacitors C1, C2, and C3 between the live wire connector L and the rectifier circuit DB1 on the bridge, and three step-down capacitors C1, C2, and C3 A step-down capacitor bank is formed; a fuse FR1 is also set between the zero line connector N and the rectifier circuit DB1 on the bridge. This embodiment adopts a double-sided circuit board, and SMD chip components are respectively pasted on the top layer and the bottom layer of the double-sided circuit board. Capacitor pins are covered with Te...

The invention discloses a drive power supply for a miniaturized LED filament lamp and its assembly process, including a zero line connector N, a live line connector L, the neutral line connector N, and the live line connector L are connected to the rectifier circuit DB1 on the bridge, and the rectifier circuit DB1 on the bridge The output terminal is filtered by the filter capacitor C4 and the resistor R1, and then connected to the filament interface LED+ and LED‑ of the LED lamp. The present invention cancels the connecting piece between the lamp cap and the LED hair bulb, and the finished lamp is closer to an incandescent lamp, and the appearance is beautiful and generous, making it easier for consumers to accept; at the same time, because the connecting piece is removed, the production process is also closer to that of an incandescent lamp. The production process of incandescent lamps is conducive to the use of automated equipment to achieve mass production.
Description
technical field [0001] The invention relates to an LED filament in the lighting field, in particular to a driving power supply for a miniaturized LED filament lamp and an assembly process thereof. Background technique [0002] In recent years, LED filament lamps have become a development hotspot. With their advantages of high brightness, high luminous efficiency, health and energy saving; The structure of a traditional incandescent lamp is a metal lamp cap with a transparent glass bulb, and the glass bulb contains a glass stem and a tungsten wire. There is no other structural parts such as power supply between the metal lamp cap and the glass bulb shell, and the lamp cap and the glass bulb shell are formed by heating, curing and bonding the lamp cap mud. [0003] There is an LED driving power supply between the metal lamp cap and the glass bulb of the LED filament lamp that replaces the incandescent lamp. According to different regions, the shape of the lamp holder connect...
