Which lamps can be dimmed
The second type is a digital signal that move light, I have seen in the history of the existing four kinds, one is 0-10 v, one is the DSI, a DALI protocol is now gm Europe, one is the American general ECO agreement. The categories mainly dimmer (or modules) that move light output control signals for transformer (or load drive), thus transformer according to the corresponding voltage signal output to load, realize the dimmer. The difference is that 0-10v and DSI are not addressable, and DALI and ECO addressable.
Dimming way I'm currently on the market only met two categories, one is the voltage adjustment, is what you say, thyristor dimmer, cut points front and along the cut after the phase two voltage waveform of the dimming ways, direct connect wire after the output voltage to load dimmer.
LED light source, can be made to adjust the light basically, can not adjust the light is all in the power supply.
Want to see the switch of lamps and lanterns, want this of my home this kind of rotation: when open slowly, turn slowly dark until close.
