Test item: street lamp test
This standard specifies the technical requirements, experimental methods, inspection rules, marking methods, packaging, transportation and storage conditions for LED lamps.
LED lamps refer to lighting lamps that use LEDs as light-emitting devices. Compared with traditional lamps with high-pressure sodium lamps and metal halide lamps as light sources, they have the advantages of energy saving, environmental protection, and long life.

⑷The safety level of lamps can be divided into four types:
Class 0 lamps: non-ground wire lamps, relying on basic insulation as protection lamps against electric shock. This means that the accessible conductive parts of the luminaire are not connected to the protective conductor in the fixed line of the facility, and in case the basic insulation fails, it has to rely on the environment.
Class I lamps: lamps with a ground wire. The electric shock protection of lamps not only relies on basic insulation, but also includes additional safety measures, that is, connect easily accessible conductive parts to the protective grounding conductor in the fixed line of the facility to make it easy to reach The conductive parts in the basic insulation will not be charged in case of failure of the basic insulation.
Class II lamps: non-ground wire lamps, anti-shock protection not only depends on basic insulation, but also has additional safety measures, such as double insulation or reinforcement, but there is no protective grounding measure or depending on installation conditions.
Class III lamps: Anti-shock protection depends on the power supply voltage being a safe and extra-low voltage (the effective value of AC voltage is less than 50V), and it will not produce lamps with a voltage higher than SELV.
