PWM is the abbreviation of Pulse Width Modulation, and refers to

the method of controlling signal intensity by controlling the ratio

between the ON period and OFF period of a pulse signal.

A pulse signal is a signal which repeatedly alternates between ON

and OFF, and the percentage of ON period during a single cycle is

referred to as the "duty cycle".

PWM-controlled lighting is a method for controlling the brightness

of a lamp by controlling the duty cycle (lit time) of light from a

pulse-emission source. As the lit time becomes longer, the light

becomes brighter, and conversely, as the lit time becomes shorter

the light becomes darker.

System diagram

Illuminance Meter T-10A series

Ideally, the relative spectral responsivity of the illuminance

meter should match V (λ) of the human eye for photopic vision.

As shown in the graph above, the relative spectral responsivity

of Konica Minolta Illuminance Meters T-10A/10MA is within

6% (f1´) of the CIE spectral luminous efficiency V (λ).

CIE ; Commission Internationale de I´Eclairage
f1´(CIE symbol) ; The degree to which the relative spectral

responsivity matches V (λ) is characterized by means of the error f1´.

Since the brightness at the measurement plane is proportional

to the cosine of the angle at which the light is incident, the

response of the receptor must also be proportional to the

cosine of the incidence angle.

For Konica Minolta Illuminance Meters T-10A/10MA, the

cosine response f2 is within 3%.

The graph above shows the cosine correction characteristics

of Konica Minolta Illuminance Meters T-10A/10MA.
