New and specialty ones take customer needs in mind, and fix or improve or add features that make the electronics work with a dimmer, with either resisted or pwmed dimmers. In many cases, if the fixture is compatible with 0-10V dimming, you can use any 0-10V dimmer compatible with that technology. Since they are all manufactured differently, they will all react differently to the dimming signals that our controls create resulting in varying. This may be included in the fixture, or external as is the case with LED tape light. As of now, there is no industry standard with LEDs. That’s why some people think LEDs flicker more than older light sources. For a fixture to be compatible with 0-10V dimming, it needs to have a 0-10V LED driver. So if connected directly to an AC mains-electricity supply, an LED will switch on/off 50 times each second enough to be visible to the sildenafil uk order human eye. Fall out of that range, and it won't work, and can cause damage. When the power supply to an LED is switched off, the light output stops instantly.
The ones that arn't designed for dimmers have a very very small input range (110~120 AC ± a few volts) that the electronics inside are designed for. Not just resistors, but rectifying the AC voltage, stepping it up/down, current control, ballast, etc. LED and CFLs on the other hand, have control electronics in them. A dimmer basically cuts the voltage in half (or a certain percentage depending on how much you are dimming) by resistance or by a solid state relay cutting the voltage on/off as needed (PWM, averaging the on/off periods), but the bulb still works by the filament heating up as normal, just less brightly. Nothing but metal and the filament in the bulb. A lamp or lighting fixture is directly connected to the wiring in your home, and that's it. The reason for this is that a standard incandescent bulb works off direct (AC) voltage. Controlling light intensity through a dimmer is directly related to the current being fed to the LED and when you dim your lights, you also reduce the power and as a result of this, your lamps will remain efficient.
#WHY DO YOU NEED A SPECIAL DIMMER FOR LED LIGHTS DRIVERS#
Some will work with standard incandescent dimmers, some need specific CFL or LED dimmers. 0-10v dimming drivers for LEDs allow you to create lighting to suit a mood or activity through a reliable technology. Short answer, you need special CFL or LED bulbs to work with dimmers.
