1How we will install it 我们的安装方式

We will hang the 40mm neon horizontally between rigging points, so it looks like power lines between poles. The neon hangs in the air with a natural sag. At each end we attach with 2 stainless rigging rings (doubled) plus 2 safety cables.

我们会把 40mm 霓虹灯管水平悬挂在吊点之间，外观像电线杆之间的电力电缆。灯管在空中自然下垂。每端使用 2 个不锈钢吊装环（双重）加 2 条保险绳固定。

2What we need from you 我们需要的数据

To rig this safely without damaging the LED, we need two numbers from your engineers for NL-Ws2811-60φ40:
为了安全吊装且不损坏灯珠，我们需要贵司工程师提供 NL-Ws2811-60φ40 的两个数据：
  • Weight per meter (kg/m) of the finished product. 成品的每米重量 (kg/m)。
  • Maximum safe pulling force (axial tension, in kg or N) the product can hold long-term without damage to the silicone tube or the LED strip inside. 产品可长期承受、且不损坏硅胶管和管内灯条的最大安全拉力（轴向张力，kg 或 N）。
This is a technical question only. Nothing changes on order US0185.152603.07A02. 这只是技术咨询，订单 US0185.152603.07A02 的内容不变。

3Why the pulling force matters 为什么拉力很重要

The tension is much more than the weight. The flatter (tighter) we pull the neon, the higher the force at each end. The table below shows the tension at each end for different spans and sag amounts, using an assumed weight of 1.2 kg/m (please confirm the real weight).

拉力远大于自重。灯管拉得越平（垂度越小），两端受力越大。下表按假设重量 1.2 kg/m 计算不同跨距和垂度下每端的拉力（请确认实际重量）。

Span跨距 Tight look · sag 2.5%较直 · 垂度 2.5% Normal · sag 5%正常 · 垂度 5% Relaxed · sag 10%宽松 · 垂度 10%
5 m 30 kg (66 lb) sag 0.13 m 15 kg (34 lb) sag 0.25 m 8 kg (18 lb) sag 0.5 m
8 m 48 kg (106 lb) sag 0.2 m 24 kg (54 lb) sag 0.4 m 13 kg (28 lb) sag 0.8 m
10 m our target 目标 60 kg (133 lb) sag 0.25 m 31 kg (68 lb) sag 0.5 m 16 kg (36 lb) sag 1.0 m
11 m 66 kg (146 lb) sag 0.28 m 34 kg (74 lb) sag 0.55 m 18 kg (39 lb) sag 1.1 m

Values are the tension pulling on each end of the neon, calculated with the standard cable formula T ≈ w·L² / (8·s). Example: a 10 m span pulled fairly tight (0.25 m sag) puts about 60 kg of pull on the neon ends. That is why we need the maximum rating.

表中数值为灯管每端承受的拉力，按标准悬索公式 T ≈ w·L² / (8·s) 计算。例如：10 米跨距拉得较直（垂度 0.25 米）时，灯管两端各承受约 60 公斤拉力。因此我们需要知道最大承受值。

4Questions for your engineers 请贵司工程师确认的问题

  1. What is the weight per meter of NL-Ws2811-60φ40 (kg/m)? NL-Ws2811-60φ40 的每米重量是多少 (kg/m)？
  2. What is the maximum pulling force (kg or N) the silicone tube can safely hold long-term, hanging continuously? 硅胶管在长期连续悬挂状态下可安全承受的最大拉力是多少（kg 或 N）？
  3. Under tension, which part fails first: the silicone tube, or the LED strip / solder joints inside? What is the safe limit for the complete product? 在拉力作用下，哪个部分会先损坏：硅胶管，还是管内的灯条/焊点？整个产品的安全拉力上限是多少？
  4. What maximum span between hanging points do you recommend for this install style? 对于这种安装方式，贵司建议的两个吊点之间的最大跨距是多少？

Our rigging rings and safety cables carry the vertical load at the attachment points. This question is only about the pulling force along the neon itself. If you have a datasheet or test report for the silicone tube tensile strength, please share it.

吊装环和保险绳承担吊点处的垂直载荷，本咨询仅针对灯管本身承受的轴向拉力。如有硅胶管抗拉强度的规格书或测试报告，请一并提供。
