Illumination Problem Solving

What is the value of luminous flux of a light source with 1 candela intensity and viewing angle of 40ยฐ?

NOTE:

Luminous flux:

It is the measure of the perceived power of light or the total amount of light a lamp puts out.

The SI unit of luminous flux is the lumen (lm).

One lumen is the luminous flux of the light produced by the light source that can emits 1 cd of luminous intensity over the solid angle of 1 sr.

Viewing angle:

It is a angle between the axis of the light source that can gives out a highest luminous intensity and the axis where luminous intensity decreases to 50%.

The viewing angle is also called as apex angle and the SI unit of apex angle is steradians (sr):

#### Problem Answer:

The value of luminous flux of a light source is equal to 0.38 lumen.
