RoHS has listed six kinds of harmful substances, including: Pb, Cd, Hg, Cr6+, PBDE, PBB.
Why RoHS? First noticed the electrical, electronic equipment containing heavy metals are hazardous to human health is Holland in 2000 found that cadmium in the cable of a number of market sales of the game machine. In fact, electrical and electronic products are currently widely used in the production of solder, packaging printing inks contain harmful heavy metals such as lead. The European Union was the implementation of RoHS in July 1, 2006, when the use of or containing heavy metals and PBDE, electrical and electronic products PBB flame retardant will not be allowed to enter the EU market.
IP Grade (Dustproof and waterproof)
Protection system is drafted by IEC (International Electro Technical Commission). The lamp will be with different grading in the dust, to prevent foreign material intrusion, waterproof, moisture resistant characteristics. Objects referred to here contains tools, the fingers are not touch the charged the lamp parts, in order to avoid electric shock. IP protection class is composed of two digits, the first digit indicates the lamp dustproof, prevent foreign material intrusion classes; the second number indicates the degree of moisture resistant, waterproof sealed lamps invasion. The higher the number, the higher the level of protection that. Dust level (represented by the first X), waterproof grade (in second X). The first X digital code meaning
0: No protection
1: prevent large solid invasion
2: prevent solid medium size into
3: prevent small solid into
4: prevent the invasion of solid objects larger than 1mm into
5: prevent harmful dust accumulation of
6: completely prevent dust entering
The Second X digital code meaning
0: No protection
1: drops into the outer casing
2: no effect: when the shell is tilted 15 degrees, water dripping into the shell without affecting
3: water or rain from 60 degrees corner to the housing
4: no effect: liquid from any direction poured into the shell did not damage effects of
5: rinse with water without any harm
6: can be used for the cabin environment
7: can be resistant to water immersion in a short period of time (1m)
8: in the water for a long time under a certain pressure
cases: lamps marked as IP65, said product can completely prevent dust and wash with water without any harm.
