Abstract

The utility model relates to an LED strip, which comprises an inner core, an outer sheath covering the inner core, a copper stranded wire penetrating through the inner core, and an LED lamp bulb arranged in the inner core, wherein the copper stranded wire is composed of a copper wire and a soft insulation wire; the copper wire is formed by stranding 16-25 strands of the copper lines with a cross section with a diameter of 0.16 mm and has a conductive cross area of 0.32-0.5 mm<2> to meet the requirement of current conduction of LED lamp string. The soft insulation wire can enhance the tension bearing capacity of the conductor, and can reduce the use amount of the copper wire by 39-63% in comparison with the conductor of the tungsten filament bulb strip. Accordingly, the production cost of the conductor can be reduced by 39-63%.

Description

A kind of LED flexible lighting product

Technical field

The utility model relates to decorating lighting lamp, especially a kind of LED flexible lighting product.

Background technology

Flexible lighting product is the linear decoration light fixture that is made of soft ambroin, copper stranded conductor and some miniature bulbs; because its lamp body is transparence; and can bend, twist; lamp body is under the protection of crust; effect with excellent waterproof, dustproof and insulation, so flexible lighting product is widely used in the decoration of profile and various signboard patterns etc.Because early stage flexible lighting product all is to adopt the tungsten filament miniature bulb as light emitting source, therefore the lead in the flexible lighting product lamp body is what to need to conduct than higher electric current, must bear certain pulling force, so the number of share of stock of copper stranded conductor is many, and the sectional area of single strand of copper wire is also bigger, in general, be used on the osram lamp copper stranded conductor by, the diameter of section of single strand of copper wire is 0.20mm or 0.254mm.When adopting diameter of section to be the single strand of copper wire of 0.20mm, copper stranded conductor is formed by 17～24 bursts of strand systems, and the electric current conductive cross-section is long-pending to be 0.52～0.75mm ²When adopting diameter of section to be the single strand of copper wire of 0.254mm, copper stranded conductor is formed by 12～14 bursts of strand systems, and the electric current conductive cross-section is long-pending to be 0.52～0.75mm ², this becomes a kind of habitual lamp string guide wire already.

Present stage, because the technical development of lighting field, a kind of new light emitting source is progressively replacing osram lamp commonly used, and that is light emitting diode (LED) bulb, also is like this in the flexible lighting product.Because the LED bulb has extremely low energy consumption, so the required relative osram lamp of current value of driving LED is very little, so also adopt LED as light emitting source in LED flexible lighting product lamp body.But owing to adopt osram lamp as the manufacture craft of light emitting source full maturity, even if light emitting source is changed to LED, the manufacturing process of LED flexible lighting product is still continued to use the osram lamp flexible lighting product.The copper stranded conductor of flexible lighting product is wasted one's talent on a petty job for having seemed for the LED conductive electric current like this, has wasted conductor material significantly, has increased cost of manufacture.

Summary of the invention

The utility model provides a kind of LED flexible lighting product at the problems referred to above, and it has saved the making material to a certain extent with respect to the osram lamp flexible lighting product, has reduced cost of manufacture.

In order to achieve the above object, the utility model adopts following scheme: a kind of LED flexible lighting product, comprise inner core, be coated on crust and the copper stranded conductor in the inner core on the inner core and be installed in LED bulb in the inner core, the lamp base of LED bulb is electrically connected with copper stranded conductor, it is characterized in that being provided with in the described copper stranded conductor one soft insulated wire at least; Described copper stranded conductor is formed by 16～25 bursts of copper cash strand systems, and the diameter of section of this copper cash is 0.16mm; Described inner core be provided with transverse holes in a lateral direction, the surface is provided with longitudinal fluting above described inner core.

With respect to osram lamp flexible lighting product and early stage LED flexible lighting product, LED flexible lighting product of the present utility model adopts the single strand of copper wire of 0.16mm, 16～25 of copper cash bursts of strand systems form thus, cooperate the pulling force ability to bear of soft insulated wire with the raising lead, and its conductive cross-sectional area are 0.32～0.5mm ², can save 39%～63% copper cash use amount like this, and can also satisfy the pulling force requirement.The use amount of copper stranded conductor is bigger in flexible lighting product, therefore can save a large amount of costs of manufacture.

The specific embodiment

The lamp body structure of flexible lighting product such as Fig. 1 in the utility model, Fig. 2 and shown in Figure 3, comprise inner core 1, be coated on the crust 2 on the inner core 1, and the copper stranded conductor in the inner core 3 and be installed in LED bulb 4 in the inner core, the lamp base of LED bulb 4 is electrically connected with copper stranded conductor 3, be provided with transverse holes 11 in a lateral direction at described inner core 1, the surface is provided with longitudinal fluting 12 above described inner core 1, LED bulb 4 is arranged at transverse holes interior 11, the lamp base of adjacent LED bulb 4 is twisted joint together, and it twists leg and 41 is positioned at longitudinal fluting 12, its manufacture craft and structure are identical with the osram lamp flexible lighting product, and difference is copper stranded conductor 3.As shown in Figure 4, copper stranded conductor 3 in the utility model comprises copper cash 31 and soft insulated wire 32, the copper cash 31 consistent diameter of sections that adopt are the copper cash of 0.16mm, there are 16～25 strands, the soft insulated wire 32 general nylon fiber lines that adopt, diameter of section is 0.2mm, and after copper cash and soft insulated wire strand system formed lead, its cross section conductive area was 0.32～0.5mm ², can satisfy the electric current conduction demand of LED lamp string, and compare with the lead described in the background technology, saved 39%～63% copper cash use amount, can also satisfy the pulling force requirement, therefore on the cost of lead, can reduce by 39%～63% cost of manufacture.
