Abstract

A method for constructing an LED filament lamp and the LED filament lamp. A lamp bulb housing (101) and a lamp holder (108) are disposed outside an LED light source core assembly, and the LED light source core assembly is connected to the lamp holder (108) by means of a wire, so as to form an LED filament lamp. The LED light source core assembly consists of an LED filament set (420), a built-in LED driving power supply module (410), and wiring terminals (44). Two ends of the LED filament set (420) are connected to fixed welding points of the built-in LED driving power supply module (410) by means of the wiring terminals (44) playing a supporting role; or, serial-connection points of the LED filament set (420) are also connected to the fixed welding points of the built-in LED driving power supply module (410) by means of the wiring terminals (44) playing the supporting role. The construction complexity of the LED filament lamp is reduced; When LED filament lamps of different typical forward voltage grade requirements are constructed by means of non-voltage-reduction rectifying power supply under different mains supply voltage grades, an LED filament can have higher universality and interchangeability.

Description

technical field

[0001] The invention relates to a construction method of an LED filament lamp and an LED filament lamp, belonging to the technical field of LED lighting. Background technique

[0002] In the past, to achieve a certain illuminance and illumination area for LED light sources, it was necessary to install optical devices such as reflective surfaces and lenses, which affected the lighting effect and reduced the energy-saving effect of LEDs. Multiple LED chips or LED PN junctions are packaged on a strip-shaped substrate in the form of an LED series group, preferably a transparent strip-shaped substrate, to form an LED filament. The LED filament can emit light at all angles of 360°. It emits light at a large angle without adding a lens, realizing a three-dimensional light source and bringing an unprecedented lighting experience.

[0003] It is the best solution for general lighting to supply LED filament lamps directly with the mains power supply. If the LED filame...
