The invention discloses an LED (Light Emitting Diode) filament lamp. The LED filament lamp mainly comprises a lamp cap, a glass bulb and a filament lamp bracket which is arranged in the glass bulb and is fixedly arranged on the lamp cap, and is characterized in that the filament lamp bracket is formed by connecting an upper clamping plate and a lower clamping plate through a middle stand column, wherein the upper clamping plate and the lower clamping plate consist of printed circuit boards respectively; the respective outer edges between the upper clamping plate and the lower clamping plate are connected with uniformly distributed multiple LED filaments; the two ends of the LED filaments are welded to the upper clamping plate and the lower clamping plate by reflow soldering or a drying box through solder paste printed or spotted on the bracket and are mutually connected by a copper foil wire on the upper clamping plate and the lower clamping plate; the filament lamp bracket structure is fixedly arranged on the lamp cap through a glass core column; the copper foil wire on the lower clamping plate is connected to an electrode in the lamp cap through a core column lead-out wire; a core column exhaust tube is connected below the filament lamp bracket structure. The LED filament lamp has the characteristics of rational structure, capability of improving the labor production efficiency, easiness in automatic production and the like.
Description
technical field [0001] The invention relates to an LED filament lamp, which is used for lighting and decoration. Background technique [0002] As a green energy-saving light source, LED lamps are widely used at home and abroad, and filament-shaped LED lamps are more popular with consumers because of their high luminous efficiency and small size, which are similar to incandescent lamps and can be directly and conveniently replaced by incandescent lamps. Due to its inherent characteristics, the LED filament lamp needs to be spot-welded to the wick bracket with a spot welding machine. The work efficiency is low, it is easy to weld and desolder, and it is difficult to automate production. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a reasonable structure, easy to use, neither need to use the spot welding machine to spot weld the filament, but also solve the low work efficiency of the sp...
