| الوصف: | Temporal light modulation (TLM) is a change in the luminous quantity or spectral distribution of light with respect to time of either a light source or a lighting system. These changes arise because of the device or system design, including drivers and control gear, and because of fluctuations in the electrical supply. In former times, families of lighting products all exhibited the same (or approximately the same) TLM characteristics: For example, AC-powered incandescent lamps shared the property of TLM in a sinusoidal wave at twice the mains frequency and 4%–10% modulation depth. T8 fluorescent lighting systems with electronic ballasts operated with a dominant frequency between 20 kHz and 40 kHz and little modulation depth. Previously, knowing the lighting technology provided sufficient information about the TLM properties of a lighting system; today, this is impossible without measuring the system directly. |
