There are only two, one larger unit and one smaller unit. Since there are many different types of lighting, each with its own strength, there are also different units for candela. The three terms indicate how much light a lamp emits and how much light it produces. So the three terms all have different meanings, but they are related. When a light beam with a strength of one lumen falls on an area of exactly one square metre, you are dealing with one lux. This therefore helps to determine the light pattern to determine. The number of lux indicates how much light reaches the desired surface. This is therefore different from the total luminous intensity. Lumen represents the total luminous flux of a light beam. This is because the three terms are closely related. When it comes to candela, the terms lumens and lux is also often mentioned. Relationship between candela, lumen and lux The other basic units are: time in seconds, length in metres, mass in kilograms, electronic current in ampere, absolute temperature in kelvin and amount of substance in mol. Candela is also one of the seven basic units of the SI system. But what exactly is the luminous intensity? The luminous intensity indicates how much light is contained in each section of the light beam. This is why one candela corresponds to the luminous intensity of a normal candle. The word comes from Latin and literally means candle. It does not store any personal data.Candela is the unit of luminous intensity and is indicated by the letters CD.

Iv (cd) = фv (lm) / 2∏ (1 – cos (Ө/2)), where the luminous intensity in candela is calculated by dividing the luminous flux in lumens by two time pi multiplied by one minus the cosine of half the cone apex angle in degrees. Ω (sr) = 2∏ (1 – cos (Ө/2)), which means that the solid angle in steradians is calculated by multiplying two times pi by one minus the cosine of half the cone apex angle in degrees. Iv (cd) = фv (lm) / Ω (sr), which means that for a uniform isotropic light source, the luminous intensity in candela is calculated by dividing the luminous flux in lumens by the solid angle in steradians. This calculator uses a particular formula in performing the calculations. The luminous intensity result in candela will be Afterwards, click the ‘Calculate’ button. When using the calculator, you will first enter 455 in the luminous flux in lumens text field and apex angle respectively. If the luminous flux in lumens is 455 lm with an apex angle of 56°, determine the luminous intensity in candela. Your luminous intensity result in candela will be displayed in the bottom platform of the calculator below the two controls. If you want to perform new calculations, the ‘Reset’ button will be useful in erasing all previous data in the text fields. Afterwards, click on the ‘Calculate’ button to initiate the conversion. Proceed to the next text field where you enter the apex angle in degrees. The initial step is to enter the value of luminous flux in lumens. Since lumens and Candela are of different quantities, they cannot be converted directly and requires the apex angle in degrees. It is a conversion calculator that converts the luminous flux in lumens (lm) to the luminous intensity in candela (cd).
