What does IP means in LED drivers

The waterproof level of LED drivers is specified by two numbers known as Ingress Protection (IP) ratings, which are a measure of the environmental protection that the driver provides.

The first number of the IP rating specifies the driver’s protection against solid materials, whereas the second figure specifies protection from liquids. A description of the levels of each of these two numbers is shown in the table below.

IP First number – Protection against solid objects

0No special protection
1Protected against solid objects   over 50 mm, e.g. accidental touch by a persons hands.
2Protected against solid objects over 12 mm, e.g.   persons fingers.
3Protected against solid objects   over 2.5 mm (tools and wires).
4Protected against solid objects over 1 mm (tools,   wires, and small wires).
5Protected against dust limited   ingress (no harmful deposit).
6Totally protected against dust.

IP Second number – Protection against liquids

0No protection
1Protection against vertically   falling drops of water e.g. condensation
2Protection against direct sprays of water up to 15o   from the vertical
3Protected against direct sprays   of water up to 60o from the vertical
4Protection against water sprayed from all directions –   limited ingress permitted
5Protected against low pressure   jets of water from all directions – limited ingress
6Protected against temporary flooding of water, e.g. for   use on ship decks – limited ingress permitted
7Protected against the effect of   immersion between 15 cm and 1 m
8Protects against long periods of immersion under   pressure
