Amongst the issues of led power supply 12v is one of the latest challenges still yet to be fully solved. Dimming LEDs is theoretically easy, because analogue dimming, which is the adjustment of current, is definitely an option. However, this technique only works safely when combined with one LED bulb. Systems of LEDs require a more sophisticated method of dimming. The two basic forms of dimming are definitely the PWM or Pulse-Width-Modulation as well as the analogue dimming, both of which are switched-mode regulators. Both of these types are similar in the sense that they both control the time-averaged current through the diode.

Analogue dimming is definitely a simple method of dimming, this is the adjustment of cycle-by-cycle in the LED current regulated with a potentiometer. The current is adjusted to the LED increasing and decreasing its intensity.

The disadvantage of analogue dimming is it only works safe as long as we dim just one light bulb. Systems of Leds need a more refined technique. The difficulty of dimming a system of LED lights is there are various types of LEDs, requiring various ways for dimming. If you have a system of lights we wish to dim, the many LEDs may react diversely towards the equivalent amount of current, and because the current is reduced some LEDs can make off later or earlier than others. Also, analogue dimming largely changes the colour from the light, similarly to after it is used in combination with incandescent lights.

Probably the most frequently used manner of LED dimming diver is Pulse-Width Modulation, which is simply the cutting of the phase at a certain frequency. PWM switches the devices between fully on and fully off with a frequency that should not be told by the human eye, therefore LED bulbs always run on the forward current recommended. The frequency of switching determines the brightness of light, therefore the longer the lighting is “on” the brighter the lighting will likely be. This is actually the same technique used in incandescent light dimmers too, other than incandescent lights respond to current more slowly, and therefore need a different frequency.

Two kinds of Pulse-With Modulation signals are used often with dimming light: the leading-edge and also the trailing edge techniques. Both of these will vary methods for cutting the phase, and lead to separate dimming technologies. By far the most frequently used dimmers of LEDs use solely the top-edge technology.

Dimmers marked as R or RL are compatible with most dimmable LEDs, given that they work together with the key edge technology and do not include electronic transformers. TRIAC drivers, or devices governed from the DMX and digital addressable lighting interface (DALI) protocols and, in the future, may include wireless (RF) as a control option, that is certainly dimmers that turn or slide using a knob, all assist dimmable LEDs. Alas leading edge technologies controlled with a touch or push button, are nzyjty powered by an electric powered transformer, excluding many dimmable LEDs.

Another type of phase-cutting strategy is trailing edge technique, usually utilized in MOSFET or perhaps is not suitable for almost all dimmable LEDs. One of the latest inventions appearing on the marketplace is the RAIS lamp technology. RAIS lamps offer a higher amount of functionality and seem to work with all types of dimmers available on the market. However RAIS technology is still new, along with its long term influence on LEDs have not been fully tested. Should they end up being trustworthy their application both domestically and commercially, can come to be much safer and much easier than previous dimmable LED lights’.

In the ever-evolving technologies of Leds, LED dimmable divers are still to become designed to further compatibility and better performance. Since there is no general rule for which dimmer your LED might be ideal for, check the technical details using the distributor. Use of Leds with non-compatible dimmers might ruin the LEDs, plus they are, at the moment, not the most affordable solution of lighting.
