There are many wires inside the LED lamp holder, and if it is to be able to operate normally, it needs correct wiring. So, what standard should the internal wiring of the LED lamp holder meet? There is a detailed introduction in the following, we can come to understand in detail.

According to the requirements of the GB7000.1 standard, when the normal current of the positive bayonet lamp holder is less than 2A (generally the operating current of the LED lamp holder does not exceed 2A), the nominal cross-sectional area of the internal wire is not less than 0.4mm2, and the thickness of the insulating layer is not less than 0.5mm . Moreover, from the perspective of insulation, because the aluminum shell is a touchable metal part, the internal insulation cannot be touched directly with the aluminum shell. This requires that the internal wires must be two-layer insulated wires, unless there is a relevant certificate that can prove that the insulation layer of the wire can be used. To meet the requirements of reinforced insulation, it is also possible to use single-layer insulated wires for internal wires. However, the internal wires used by LED lamp holders on the market rarely take into account the requirements of cross-sectional area, insulation thickness and insulation wire level at the same time.

In addition, when the internal wires of the LED lamp holder are routed, attention should be paid to prevent the wires and the internal power supply components from directly touching the heat, such as transformers, filter inductors, bridge stacks, heat sinks, etc., because these components are in the LED lamp holder During operation, the temperature is likely to exceed the heat-resistant temperature value of the internal wire insulation material. When the internal wires are routed, do not touch the parts with high heat generation, which can prevent the insulation layer from being damaged due to local overheating of the insulation layer, and safety problems such as leakage or short circuit.
