CONTROL TWEAKS

摘要

The Many Advantages of light-emitting diodes (LEDs) for general illumination have outweighed their limitations, except when it comes to dimming. Though they have not been without challenges in the area of controls, new solid-state lighting standards and expanded retrofit dimming capabilities are designed to position LEDs for greater compatibility as incandescent technologies phase out of existence. Performance enhancement, industry experts contend, will not be a quantum leap. LEDs are functionally friendly with controls in two important ways. First, LED luminaires are high-efficiency, instant-on devices. The lamps are rated at hours per start and can be switched on and off repeatedly without affecting their lamp life, unlike compact fluorescent lamps (CFLs) or high-intensity discharge (HID) lamps; these lamps' rated life is an average that decreases as switching frequency increases.
