Embodiment Construction

[0011] like figure 1 As shown, a dedicated stem for LED filament lamps, including an inverted trumpet tube 1 and an exhaust rod 2, the exhaust rod 2 is vertical in the horn tube 1, and the two sides of the exhaust rod 2 are provided with wires 3 parallel to each other. A wire node 4 is arranged on the top, and a solid mandrel 5 is placed on the top of the trumpet tube 1, and the upper end of the solid mandrel 5 is bonded with a short nickel wire 6.

[0012] Put the trumpet tube 1, exhaust rod 2, guide wire 3, and solid mandrel 5 into the corresponding equipment of the core column machine, and make it unbonded by preheating, heating, flattening, blowing, drilling, and annealing. The stem of wire, then the solid mandrel 5 is heated and bonded with short nickel wire 6 to make a special stem for LED filament lamps.

Abstract

The invention discloses a special stem for an LED (Light Emitting Diode) filament lamp, including an inverted bell pipe and an exhaust pipe, wherein the exhaust pipe is vertically arranged in the bell pipe, wires are arranged on the parallel positions on two sides of the exhaust pipe, wire nodes are arranged on the wires, a solid core rod is placed on the top of the bell pipe, and the upper end part of the solid core rod is stuck with a short nickel wire. The special stem of the LED filament lamp has the advantages that: the LED filament lamp made from the special stem has the effects on saving energy and reducing emission, the LED filament lamp has the characteristics of small current and high voltage, the special stem is low in cost, long in service life, simple to operate and saving in cost.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a stem dedicated to an LED filament lamp. Background technique [0002] The filaments of traditional lighting fixtures are generally composed of tungsten wires and other metal wires that can directly emit light. Such filaments generally have defects such as short life and high power consumption, and generally only emit yellow light, with poor color rendering. Because LED has the characteristics of energy saving, longevity, environmental protection, and solid-state packaging, LED lights are gradually replacing traditional lighting fixtures. Existing LED lights are generally equipped with light-emitting modules, including square or round brackets, and LED chips set on one side of the bracket. , and the lens wrapped on the surface of the LED chip. With the development of science and technology, the technology of LED patch and welding is becoming more and more mature. In the existing technol...
