How a Dimmer Works
There are several types of dimmers generally available. Those employing triac or thyristor devices operate in a very similar fashion. These are used for resistive, and inductive loads, such as incandescent, cold cathode and low voltage (inductive) lamp sources. Note that not all electronic transformers used for low voltage lamps are suitable for dimming by triac or thyristor dimmers. Specialist...
متن کاملAutomatic Headlight Dimmer a Prototype for Vehicles
Headlights of vehicles pose a great danger during night driving. The drivers of most vehicles use high, bright beam while driving at night. This causes a discomfort to the person travelling from the opposite direction. He experiences a sudden glare for a short period of time. This is caused due to the high intense headlight beam from the other vehicle coming towards him from the opposite direct...
متن کاملSensitivity and Removed THD of a Phase- Cutting Dimmer
In this paper, we consider a designed and implemented phase-cutting dimmer. In fact, the dimmer is closed loop and a microcontroller calculates and then regulates the firing delay angles of each channel. Depending on the firing angle, the harmonic distortion in the input current will not comply with international standards, such as IEC 61000-3-2 (class C equipments). For solving this problem, e...
متن کاملDIMMer: A case of turning off DIMMs in clouds
Lack of energy proportionality in server systems results in significant waste of energy when operating at low utilization, a common scenario in today’s data centers. However, even during times of low utilization, servers cannot be powered off because of unpredictable spikes in instantaneous demand on some of the resources (e.g., file storage). To mitigate energy waste, unused processor cores tr...
متن کاملThe differential diagnosis of nummular keratitis (Dimmer) and epidemic keratoconjunctivitis.
Very rarely have two eye diseases been so widely confused as nummular keratitis (Dimmer) and epidemic keratoconjunctivitis. Confusion in the literature has there fore occurred and this has made studies on etiology more difficult. The mistaking of these two diseases is surprising in view of Dimmer's excellent description of his cases in 1905, and in view of Salzmann's presen tation of more tha...
