Luminous Intensity in Direction at Angle

Go Luminous Intensity at Angle = Luminance Normal to Surface*Surface Area*cos(Angle to Normal)

Luminous Flux Transmitted by Object

Go Luminous Flux Transmitted by Object = Transmission Factor*Luminous Flux Incident upon Object

Luminous Flux incident upon Object

Go Luminous Flux Incident upon Object = Luminous Flux Transmitted by Object/Transmission Factor

Transmission Factor

Go Transmission Factor = Luminous Flux Transmitted by Object/Luminous Flux Incident upon Object

Luminous Intensity in Direction Normal to Surface

Go Luminous Intensity Normal to Surface = Surface Area*Luminance Normal to Surface

Reflected Luminous Flux

Go Reflected Luminous Flux = Incident Luminous Flux*Reflection Factor

Incident Luminous Flux

Go Incident Luminous Flux = Reflected Luminous Flux/Reflection Factor

Reflection Factor

Go Reflection Factor = Reflected Luminous Flux/Incident Luminous Flux

Area Projected at solid angle

Go Area Projected at Solid Angle = Magnetic Flux/Luminous Intensity

Intensity on Solid Angle

Go Luminous Intensity = Magnetic Flux/Area Projected at Solid Angle

Flux at Solid Angle

Go Magnetic Flux = Luminous Intensity*Area Projected at Solid Angle

Photoelectric Sensitivity

Go Photoelectric Sensitivity = Photoelectric Current/Luminous Flux

Photoelectric Current

Go Photoelectric Current = Luminous Flux*Photoelectric Sensitivity

Light flux

Go Flux = Photoelectric Current/Photoelectric Sensitivity

Illuminance

Go Illumination = Magnetic Flux/Surface Area

Area affected by Light Incident

Go Surface Area = Power/Irradiation

Irradiation

Go Irradiation = Power/Surface Area

Light Power

Go Power = Surface Area*Irradiation

Luminous Flux Transmitted by Object Formula

Luminous Flux Transmitted by Object = Transmission Factor*Luminous Flux Incident upon Object
L_t = τ*L_i

What is Luminous Flux?

Luminous Flux is the total amount of visible light emitted by a source per unit of time, measured in lumens. It represents the overall brightness of light emitted, regardless of its direction, and is essential for assessing the light output of lamps and light fixtures.

How to Calculate Luminous Flux Transmitted by Object?

Luminous Flux Transmitted by Object calculator uses Luminous Flux Transmitted by Object = Transmission Factor*Luminous Flux Incident upon Object to calculate the Luminous Flux Transmitted by Object, The Luminous Flux Transmitted by Object formula is defined as is the measure of the perceived power of light. It differs from radiant flux, the measure of the total power of electromagnetic radiation, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. Luminous Flux Transmitted by Object is denoted by L_t symbol.

How to calculate Luminous Flux Transmitted by Object using this online calculator? To use this online calculator for Luminous Flux Transmitted by Object, enter Transmission Factor (τ) & Luminous Flux Incident upon Object (L_i) and hit the calculate button. Here is how the Luminous Flux Transmitted by Object calculation can be explained with given input values -> 32.34 = 4.2*7.7.
