【Technical Information】What is total luminous flux? What is total radiant flux?
How can we define the brightness of a light source that has an individual and unique directionality?
We will introduce the light source, total luminous flux, and total radiant flux of LEDs. Each light source has its own unique directionality. Directionality refers to the variation in the intensity of light emitted from a light source depending on the direction. (Light emitted only in a specific direction, such as from a laser, is described as having good directionality.) To compare the "brightness of the light source itself," it is necessary to measure the "amount of light emitted in all directions from the light source." 【Measurement Methods】 ■ Total luminous flux (total radiant flux) measurement using an integrating sphere - By homogenizing the directionality of the light source being measured, it allows for easy measurement of total luminous flux. ■ Total luminous flux (total radiant flux) measurement using a photometric measurement system - A system that measures the light distribution characteristics (directionality) of the light source. *For more details, please refer to the external link or feel free to contact us.
