The common safety hazards encountered within the E27 Lamp holder area unit are sometimes divided into the subsequent points: structure, internal wiring, anti-shock protection, insulation resistance, and electrical strength. Therefore, let's take a glance next.
Here is that the content list:
Insulation resistance and electrical strength
Protection against electrical shock
Internal wiring
Mainly mirrored within the electrical classification, the light-emitting diode Led E27 Lamp holder belongs to the II kind of anti-shock sort, which needs the input of the light-emitting diode E27 Lamp holder to the accessible components and also the input to the installation surface to fulfill the strengthened insulation level of insulation. Electrical phenomenon and insulator strength necessities. At present, several light-emitting diode E27 Lamp holders will pass the insulation resistance check, however, the insulator strength check fails, principally thanks to the choice of the electrical device with the inbuilt power offer and also the installation position of the metal substrate of the light-emitting diode module. Several firms favor using non-isolated transformers for cost-saving or high power offer potency, which can cause the inbuilt power offer to fail to fulfill the necessities of the strengthened insulation level between the input and output terminals. At an equivalent time, thanks to the direct contact between the metal substrate of the E27 Light Lamp holder module and also the metal shell throughout installation, the insulation level between the input terminal and also the accessible components cannot meet the necessities of the strengthened insulation level.
In terms of protection against electrical shock, the light-emitting diode E27 Lamp holder could also be unqualified. One is that the unreliable association between the lamp holder and also the lamp body, which ends up in the direct removal of the lamp holder by human hands, that ends up in direct contact with internal live components within the check. The second is that the interior insulation of the E27 Lamp holder isn't done well, leading to an outflow of the shell.
According to the necessities of the GB7000.1 customary for the interior wiring of the E27 light-weight Lamp holder, the interior wiring employed by the light-emitting diode lamp holder must be evaluated in four aspects: wire diameter and insulation thickness, mechanical injury, the heating temperature of the insulation layer, and whether or not the insulation meets the necessities. Typically speaking, there'll be no issues with the interior line within the protection of mechanical injury, and also the main issues can exist the opposite 3 aspects. In step with the necessities of the GB7000.1 standard, once the conventional current is a smaller amount than 2A (generally the operating current of the light-emitting diode lamp cap doesn't exceed 2A), the nominal cross-sectional space of the interior wire isn't but zero.4mm2, and also the thickness of the insulating layer isn't but zero.5mm. Moreover, from the attitude of insulation of the E27 Light Lamp holder, since the metal shell is Associate in Nursing accessible metal half, the interior basic insulation of the E27 light-weight Lamp holder cannot directly contact the metal shell, which needs the interior wires to be double insulated wires, unless the relevant certificate will prove it .The insulation layer of the wire will meet the necessities of strengthened insulation, and it's additionally attainable to use a single-layer insulated wire for the interior wire. However, the interior wires employed in this light-emitting diode E27 Lamp holder on the market seldom take into consideration the necessities of cross-sectional space, insulation thickness, and insulation wire level at an equivalent time.
