What does the luminaire protection rating IP mean

It belongs to the electrical safety protection level specification, the IP protection level is composed of two numbers, the first number indicates the level of electrical dust and prevention of foreign intrusion, the number is from 0-6, the second number indicates the airtightness level of the electrical appliance against moisture and waterproof intrusion, the larger the number means the higher the protection level, the number is from 0 to 8.

The degree of protection of the luminaire.

IP65 is contact protection and foreign object protection class 6, the protection range is medium base dust enclosure, and dust should not enter the cabinet at a low pressure of 20 mbar. The waterproof protection level is level 5, and the protection range is to protect against water jets, and water jets aimed at the cabinet from every direction should not cause damage.

The protection level of the lamp IP55 is contact protection and foreign object protection level 5, the protection range is to protect against dust, it is impossible to completely prevent dust from entering, but the amount of dust entering will not cause harm to the equipment. The waterproof protection level is level 5, and the protection range is to protect against water jets, and water jets aimed at the cabinet from every direction should not cause damage.

Extended Information: Principles for the Selection of Lamps and Lanterns:

In the lighting design, the lamps and lanterns that not only meet the requirements of the use function and lighting quality, but also facilitate installation and maintenance, and have low long-term operation costs, should be considered

1) Optical characteristics, such as light distribution and glare.

Control; 2) Economy, such as lamp efficiency, initial investment and long-term operating costs, etc.;

3) Special environmental conditions, such as fire hazard, dangerous environment, dust, moisture, vibration and chemical corrosion environment;

4) The appearance of lamps and lanterns should be coordinated with the building;

5) High efficiency of lamps and lanterns: =l o, depending on the shape and material of the reflector, the light outlet.

size, diffuser or grille shape and material;

6) IP level that meets environmental conditions.

IP is the abbreviation of Ingress Protection, IP rating is the level of protection against foreign objects in the enclosure of electrical equipment, ** is the International Electrotechnical Commission standard IEC 60529, this standard was also adopted as the American National Standard in 2004. In this standard, for the protection of electrical equipment enclosures against foreign objects, the format of the IP rating is IPXX, where XX is two Arabic numerals, the first number indicates the range of the equipment against fine dust, or the degree to which people are protected from hazards in a sealed environment; i stands for the level of protection against the ingress of solid foreign matter, and the highest level is 6; The second number indicates how waterproof the device is; P stands for the level of protection against water ingress, and the highest level is 8. For example, the protection level of the motor is IP65, the protection level is IP55, etc.

IP65 and IP55 test levels separately. The first number indicates the dust resistance level: 5 Dust resistance cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the electricity; 6 Dustproof Completely prevent dust ingress.

The second number, 5, indicates a waterproof rating of 5 to prevent water from splashing in all directions.

IP5X6X grade is generally tested with dustproof test chambers, and Lishan's SC series dustproof test chambers fully meet IEC60529 and the corresponding national standard GB4208, and are specially designed for IP5X and IPX6 tests for lamps and other electronic products.

The IPX5 waterproof level is generally tested with the anti-flush test system, and Lishan's JL-X series waterproof test equipment fully meets the IEC60529 and the corresponding national standard GB4208, and can be tested from IPX1 to IPX8.

It can do IP55, and IP54 can also do.

I can do the IP protection level test of lamps and lanterns here, and the state-owned third-party authoritative testing agency has a high authority in issuing reports.

In the Fire Emergency Lighting and Evacuation Indication System GB17945-2010.

Each component of the system shall have protection level requirements, and the protection level of the enclosure shall not be lower than the IP30 requirements specified in GB 4208-2008; and should meet the requirements of its nominal protection level.

The protection level of the shell of the fire emergency lamps installed on the indoor ground shall not be lower than IP54 specified in GB 4208-2008, and the protection level of the shell of the lamps and lanterns installed on the outdoor ground shall not be lower than IP67 specified in GB 4208-2008, and shall comply with its nominal protection level.

In the Technical Standard for Fire Emergency Lighting and Evacuation Indication Systems GB51309-2018.

The level of protection of the lamps and their connecting accessories in paragraph 7 shall comply with the following provisions:

1) When set up outdoors or on the ground, the protection level should not be lower than IP67;

2) When installed in tunnel sites and wet places, the protection level should not be lower than IP65;

3) The protection level of Type B lamps should not be lower than IP34.

The selection of emergency lighting controller shall comply with the following provisions:

3. In tunnel sites and wet places, products with a protection level of not less than IP65 should be selected; In the electrical shaft, products with a protection level of not less than IP33 should be selected;

When the lamps are powered by their own batteries, the design of the emergency lighting distribution box shall comply with the following provisions:

1. The selection of emergency lighting distribution box shall comply with the following provisions:

2) In tunnel sites and wet places, products with a protection level of not less than IP65 should be selected; In the electrical shaft, products with a protection level of not less than IP33 should be selected;
