Leds can be used to adjust the brightness with a normal incandescent light dimmer.
In not, want to use cheap ordinary dimmer, then you might also use halogen lamp cup shoots the light, technology is mature, the dimming effect is better, while demanding more electricity, but light also cheap ah, only 3 to 4 yuan a, it is important to the dimming effect is good, stable, color is also the highest, much better than common LED to shoot the light.
So, be cautious if it don't go with LED lamp dimming, unless you use the LED light source manufacturer specifically recommended combination of transformer and dimmer, otherwise, can need not to test. Lights are old expensive, spend money not worth it.
Because, currently on the market for the most part common dimmer and transformer is after cutting, and also is uneven levels, coupled with the decoration of the LED three bead lamp manufacturing estimate is not a big company, compatibility cannot guarantee, so the judgment on the basis of my experience, 99% installed, shoot the light will be flashing, if that move light will flash more severe; If you run into a poorly protected LED or dimmer, it's not a good thing to do, it's not the LED light that's burnt, it's the dimmer that's burned by the big current.
LED light, you mean low voltage 12V or 230V? If it's 12V, the light dimmer is not enough, you have to connect the transformer in the circuit, otherwise the light will burn. Instant connections, estimates that 99% is not enough, because want to let the LED MR16, MR11 shoot the light and the combination of dimmers + transformer matching without flashing, is a technical difficulties, and the head of the LED light source manufacturer will publish a and LED lamp dimmer and transformer matching brands, types and models of CRT, want to match all 100%, in the present on the earth is not human can do, see later, (want Daniel)
