What does LED mean?
LED means "Light Emitting Diode". Basically it is a semiconductor which emits light of narrow spectrum of radiation when an electrical voltage is supplied in the direction of forward bias (forward-biased).
What is Lumen (lumen)?
The Lumen (symbol: lm) (lumen) is the unit of luminous flux (luminous flux). It measures the power of light as it is perceived by the human eye. The luminous flux is different from the radiation flux. It measures the total power of radiated light. To Lumen defined in relation to the Candela.
lm = cd x sr (where sr = solid angle = solid angle).
What does Lux (lux)?
To Lux (symbol: lx) is the unit of SI (International System) measurement of the light power per unit area. It is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.
Why to choose LED lighting products?
- We save money thanks to low power consumption
- They have a long life span (30,000 hours)
- They placed directly and easily
- They emit little heat
- They do not emit ultraviolet (UV) radiation and do not contain mercury
- Recommended for all areas
What is the life span of LED products?
With an operating time of 2.7 hours / day, the life span of a LED product is estimated at 30,000 hrs.
How to determine IP rating?
The IP rating specifies the strength of the housing, which protects the active parts from foreign bodies, dust and the influx of water. The IP rating defined by two digits:
The first digit takes values from 0 to 6. On the one hand, defines how much the housing prevents access to dangerous parts, either preventing or limiting the input of body parts (eg. Finger) or objects held a person (eg screwdriver). On the other hand, specifies how much the housing protects the live parts from dust.
The second digit takes values from 0 to 8. Determine how much the housing protects the conductive parts of the incoming water and the damage water could cause.
The European standard EN 60529 specifies how to install housing during tests, the atmospheric conditions should prevail, the size and dimensions of the different objects that can be used, and also the proper allocation of water or dust to simulate actual operating conditions.
