Ingress Protection

6

First Number: 

Solids

5

Second Number:

Liquids

  • The first number identifies the protection degree against the entry of solid objects
  • 1. Protection against the entry of solid bodies with dimensions more than 50mm.
  • 2. Protection against the entry of solid bodies with dimension more than 12mm.
  • 3. Protection against the entry of solid bodies with dimension more than 2,5mm.
  • 4. Protection against the entry of solid bodies with dimension more than 1mm.
  • 6. Complete protection against the entry of dust.
  • The second number identifies the protection degree against the entry of liquid
  • 0. No protection.
  • 1. Protection against vertical falling of water drops.
  • 2. Protection against the falling of water with maximum inclination of 15°.
  • 3. Protection against rain.
  • 4. Protection against water splashes.
  • 5. Protection against water jets.
  • 6. Protection against big waves.
  • 7. Protection against the effects of limited periods of immersion.
  • 8. Protection against the effects of total submersion indefinitely.

Accent Lighting:

It focuses light on a specific object or area. It is commonly used to create visual interest in galleries and visual displays.

Ambient Temperature:

It is the air temperature surrounding a lighting fixtures. The majority of LED light bulbs have incorporated heat sinks that help them dissipate hear and perform perfectly even under extreme temperatures.

Beam Angle:

Is is the measure of how light is distributed from a bulb. A small beam angle means the beam of light emitted is narrow and very focused, while a larger beam angle covers a wider area.

Filament:

It is a conducting wire or thread with a high melting point that glows in an incandescent lamp when an electrical current is passed through it.

DEGREE OF ELECTRICAL PROTECTION

Class I:

Luminaires that require an earth connection. All parts of this type of product where conductive parts could be touched, and in case of defect can cause an electric shock, require earth protection.

Class II:

Luminaires that do not require earth connection. Double insulated materials are used in fabrication, therefore no parts could cause an electric shock by accidental touch.

Class III:

Luminaires for low voltage use (not exceeding 24V) supplied through a safety transformer such as LED’s or low voltage lamps.

Light Output:

Kelvin (K):
Represents the colour temperature of a light source.

Below is a breakdown of typical colour temperatures used:

3000K – Warm white light

4000K – Natural white light

6000K – Cool white light

Colour Rendering Index:

Colour Rendering Index (CRI) is a measure of the ability of a light source to reveal the colours of the environment around it accurately. It has a maximum score of 100, where any value above 90 is considered excellent. Any score below 80 is generally considered poor.

Dimmable:

The ability to fix a compatible dimmer switch onto a light bulb and use it to vary the light output.

RGB:

Red, Green, Blue (RGB), the three hues of light that can be combined to create different colours.
