The work of a light meter

Key Ingredients Metering The photo sensor and the measurement display. The light-emitting diodes have the function of receiving light, which is a form of energy converted into an analog electrical signal. And processed by a controller that converts brightness to digital. By the display. Depends on manufacturer design.

แสง Properties of the wave. And the energy depends on the frequency of the light. Based on the assumptions of Max Planck (E = nhf). Measurement unit of light There are several measurement units, including:

1. Brightness temperature (temperature)

2. Illuminance (illuminance or illumination) (SI unit: lux)

3. Luminous flux (SI units: lumen)

4. Luminous intensity (SI units: candela)

5. Brightness of light (brilliance) or amplitude (amplitude)

6. Color or frequency.

Polarization (polarization) or angle of vibration (angle of vibration)

In general, the use of light metering for the analysis of tasks such as the quality control of the production of light bulbs. Quantity Survey Light Intensity Research into devices that affect the organism, etc. Light intensity, depending on the intensity of light from the source directly. The illumination range also affects the light intensity that reaches the object or the measuring device. So, the environment in use. Metering That's what the user must take into account.
