LED lamp filament, LED lamp and fabrication method therefor

Abstract

The invention discloses an LED lamp filament, an LED lamp and a fabrication method therefor, and belongs to the technical field of illumination. The LED lamp filament comprises a metal substrate, a first electrode and a second electrode, a first LED light emitting module and a second LED light emitting module and multiple wires, wherein the first electrode and the second electrode are connected to the first end and the second end of the metal substrate respectively; the first LED light emitting module and the second LED light emitting module are fixedly arranged on the surface of the metal substrate separately; and the multiple wires are used for electrically connecting the first LED light emitting module and the second LED light emitting module to the first electrode and the second electrode. By virtue of the LED lamp filament, the high-effect and low-cost LED illumination lamp can be realized.

Description

technical field [0001] The present disclosure relates to lighting technology, in particular to an LED filament, an LED lamp and a manufacturing method thereof. Background technique [0002] The main lighting tools currently on the market are generally traditional tungsten filaments, energy-saving tubes and traditional LED bulbs. Ideal LED lighting tools have many advantages over the above lighting tools, such as low energy consumption, long life, and environmental protection. It is an ideal light source substitute in the future. LED lighting tools have developed rapidly in the global lighting industry in recent years, and their products involve backlights, signal lights, landscape lighting, general civil lighting and other fields. [0003] But at present, LED lighting fixtures have not enough advantages in replacing traditional light sources in terms of production cost and product stability, and their luminous efficiency is less than half of the theoretical value, which nee...

Problems solved by technology

[0003] However, at present, LED lighting fixtures have not enough advantages in replacing traditional light sources in terms of production cost and product stability, and their luminous efficiency is less than half of the theoretical value, which needs to be further improved

People generally start to improve the luminous efficiency of lamps from the following aspects: First, start from the improvement of the quality and structure of the chip itself. The second is to
