Light flux of the LED
• It is necessary to enter the parameters in millilumens (mLm) or millicandelas (mCd).
• It is necessary to specify the half-brightness angle of the LED ( as a rule, specified in the specifications ).
Lumen (lm) — is a unit of measurement of light flux in the Measurement System (SI). It shows how much light a lamp can emit in all directions.
Candela (cd) — is a unit of measurement of light intensity in the Measurement System (SI). It indicates how much light a lamp can emit in one direction.
Formula used to convert lumens to candelas:
Fv= i *2π(1-cos(a))
Components of the formula:
Fv - light flux
iv - light intensity
a - half-brightness angle
The modern market offers a huge variety of lighting types, so one of the main tasks is a responsible approach to placing lighting in your space. By selecting the right light with the necessary power, you guarantee yourself an adequate and pleasant atmosphere for your space, as well as increase productivity in offices and enterprises.
When choosing light, conventional incandescent lamps are usually used, which, when selected correctly and in the right quantity, provide good lighting, and this is quite easy to do. But there are more advanced and modern types of lighting that require careful calculation. We are talking about LED lighting, thanks to the calculator the calculation will not require additional knowledge and skills.
