1、 ScopeThis standard is used to provide unified inspection items and instructions for the lighting fixtures produced by the company. This standard specifies the technical requirements, experimental methods, inspection rules, marking methods, packaging, transportation, and storage conditions for LED lamps p> LED lamps refer to lighting fixtures that use LEDs as light emitting devices. Compared with traditional lamps that use high-pressure sodium lamps and metal halide lamps as light sources, they have advantages such as energy conservation and environmental protection p>

4. Inspection instructions: 1. Electrical parameters:⑴ DC power supply lamps controlled by external power sources: voltage and current measured with voltage and ampere meters.
Attention: To measure the current, it is necessary to measure the current of a single LED lamp and a single color and record it.
⑵ For AC lamps with built-in power control, use a digital power meter to measure the voltage, current, power, power factor, and other parameters of the lamp p> ⑶ Class I lamps must undergo electrical strength, leakage current, and insulation resistance tests. The electrical strength is the breakdown phenomenon between the 220V terminal and the shell at 1500V and 1MIN. Leakage current ≤ 1.0MA. Insulation resistance ≥ 2M Ω p> The safety level of lighting fixtures can be divided into four types:
Class 0 lighting fixtures: ungrounded lighting fixtures that rely on basic insulation as protection against electric shock. This means that the easily accessible conductive parts of the lamp are not connected to the protective conductor in the fixed circuit of the facility, and in the event of basic insulation failure, they will have to rely on the environment p> Class I lamps: Ground wire lamps. The anti electric shock protection of lamps not only relies on basic insulation, but also includes additional safety measures, that is, connecting easily accessible conductive parts to the protective grounding conductor in the fixed line of the facility, so that easily accessible conductive parts do not become electrified in the event of basic insulation failure p> Class II lamps: ungrounded lamps, with electric shock protection not only based on basic insulation, but also with additional safety measures, such as double insulation or reinforcement, but without protective grounding measures or relying on installation conditions p>
Class III lighting fixtures: Lighting fixtures that rely on power supply voltage as a safe ultra-low voltage [AC voltage effective value less than 50V] for electric shock protection and do not generate * * SELV voltage p>
