Problems solved by technology

[0002] Since the Litz wire used for the LED lamp electronic transformer produced by the existing low-heat grade line is used on the LED lamp, long-term operation at high temperature will shorten the service life of the LED lamp; secondly, the LED lamp electronic transformer uses stranded wire to operate at high temperature. When the coil is prone to loose phenomenon, which is not conducive to safety

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0012] Example. A special enameled wire for LED energy-saving lamps, such as figure 1 As shown, it includes more than 7 single wires 1 twisted together (7 are taken as an example in the figure), each single wire 1 includes a copper round wire 101 and a composite paint layer outside the copper round wire 101, and the composite paint layer Including polyesterimide paint layer 102, polyamideimide paint layer 103 and thermosetting self-adhesive paint 104 successively from inside to outside, such as figure 2 As shown; the thickness ratio of the polyesterimide paint layer 102, the polyamideimide paint layer 103 and the thermosetting self-adhesive paint 104 is 50:25:25. The diameter of the single wire 1 is 0.31mm, and the stranding pitch is 12-16mm. The total thickness of the polyesterimide paint...

Abstract

The present invention discloses a special enameled wire for an LED energy-saving lamp. The special enameled wire comprises more than 7 threads of twisted single wires (1), wherein each single wire (1) comprises a round copper wire (101) and a compound paint layer outside the round copper wire; and each compound paint layer comprises a polyester imide paint layer (102), a polyamide imide paint layer (103) and thermosetting self-adhesive paint (104) in sequence from inside to outside. The thickness ratio of the polyester imide paint layer (102) to the polyamide imide paint layer (103) to the thermosetting self-adhesive paint (104) is 50 to 25 to 25. The special enameled wire for the LED energy-saving lamp has a longer service life and a higher security, and is very applicable to an electronic transformer of the LED energy-saving lamp.

Description

technical field [0001] The invention relates to an enameled wire, in particular to a special enameled wire for an LED energy-saving lamp. Background technique [0002] Since the Litz wire used for the LED lamp electronic transformer produced by the existing low-heat grade line is used on the LED lamp, long-term operation at high temperature will shorten the service life of the LED lamp; secondly, the LED lamp electronic transformer uses stranded wire to operate at high temperature. , the coil is prone to looseness, which is not conducive to safety. Therefore, there is an urgent need for a long-life and safer lead wire for LED energy-saving lamps. Contents of the invention [0003] The object of the present invention is to provide a special enameled wire for LED energy-saving lamps. The invention has higher service life and higher safety, and is very suitable for electronic transformers of LED energy-saving lamps. [0004] The technical solution of the present invention:...
