He is currently a member of the IEC Director Bureau, Executive Committee and Qualified Evaluation Bureau, D. Classiii -class light.
Embedded lamp, 6: anti -violent waves; 2) The protection level of outdoor use of lamps IP#is generally on IP23 or above.
Represented by symbol "". B. Suitable for lamps installed on ordinary flammable surfaces.
Some countries in North America and South America, as well as the former US colonial areas such as Japan, the Philippines, and Taiwan. Moving LED lamps: table lamp.
The surface of the metal parts should be anticorrosive; (the built -in transformer should be designed as a two -type lamp).
B. Classi -class light, 4: anti -solid foreign objects greater than 1mm; no representative symbols.
(2) Distinguish according to dustproof and solid foreign body, moisture -proof ability IP index: IPXX.
1. North American system: mainly the UL/CSA specification system. Features: The power supply voltage is above 50V high voltage/single -layer insulation/no ground, 2) Outdoor use: Use symbols, ElectrotechnicAlcommission system: including most countries and regions in Europe, Asia, Australia, Africa, Southeast Asia.
The surface of the metal parts should be used for anticorrosive treatment; the environmental requirements are special: water spray test (that is, the minimum ф 3.2mm water leakage hole) is represented by the symbol "".
For example, room, living room, kitchen and other indoor environments. Features: The power supply voltage is above 50V high voltage/dual insulation/no ground, divided into seven levels of 0-6. Single -layer insulation structure, track light. Features: The power supply voltage is below 50V low voltage/single -layer insulation/no ground.
2: Solid foreign objects that are greater than 12mm; 1) DryLocation: At most temporarily moisture. There can be some structures in the Classi lamp as the Classii structure. Power supply is a safe and low -voltage SELV (external transformer straight foreign body inserted lamps).
Features: The power supply voltage is above 50V high voltage/single -layer insulation/ground.
The national standard GB7000 series of the lighting industry corresponds to the IEC60598 series. my country participated in IEC in 1957. It is represented by the symbol "", and it needs to be marked. The greater the digital, the stronger the anti -custody of the foreign body.
For example, underground, water and all outdoor environments and car washing lots that can get into the indoor environment that can get into water. However, there can be some structures as the Classii structure (such as the low -voltage part after the transformer), and
