Abstract

The invention belongs to the technical field of illumination and provides an LED filament strip. LED filaments are distributed to form a long strip shape, and electric connection points at the two ends of each LED filament are connected through a wire. An LED filament lamp is manufactured through the LED filament strip and comprises a lamp holder, a lamp base and a supporting rod, the LED filament strip is arranged around the supporting rod, and an upper guide wire and a lower guide wire of the supporting rod are connected with an upper wire and a lower wire of the LED filament strip respectively. A method for manufacturing a core filament includes the steps that a core is prepared, an LED filament strip workpiece is cut, the cut LED filament strip workpiece is wound on the periphery of the core, an upper guide wire and a lower guide wire of the core are welded to wires at the upper end and the lower end of the LED filament strip workpiece respectively, and the core filament is manufactured. According to the LED filament strip, the LED filament lamp and the method for manufacturing the core filament of the LED filament lamp, procedures are simplified, welding human factors are reduced, products are good in uniformity, installation is firm and reliable, the structure is reasonable, product quality and production efficiency of the LED filament lamp are greatly improved, and great application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of lighting and relates to an LED filament lamp. Background technique [0002] With the advent of LED white light, the lighting industry has set off a second revolution. As a light source, LED is not only energy-saving and environmentally friendly, but also has a long service life, which is in line with the environmental protection, energy saving and low-carbon products advocated by the state. The cost of LED lamps will decrease with the continuous improvement of LED technology, and energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps. At present, the country pays more and more attention to lighting energy saving and environmental protection issues, and has been vigorously promoting the use of LED lamps. In particular, the government's street lamp renovation project is first of all LED street lamps, and it is specified that LED street lamps must be used. It can be seen that LED...
