Talk about intelligent dimming of LED lights

Dimming is standard in high-end smart home systems.

Led dimming refers to the brightness, color temperature and even color of LED lamps and lanterns can be adjusted. Only lamps and lanterns that can be dimmed, to be able to slowly light up, slowly shut down, different scenarios to provide different brightness different color temperature, and light switch can be smooth transition, so, high-end smart home system, standard dimmable lighting system.

For a dimmable LED lamp, at least includes dimming drive components and light-emitting components, some are further subdivided into dimming components, drive components and light-emitting components. For example, the following picture of the dimmer system, dimmer for 0-10V dimmer, the driver is LED dimmer power, and then connected to LED lamps.

Of course, most smart dimmable lights can be integrated directly into a single light fixture and connected directly to a network such as wifi or ZigBee. This dimmable light fixture is very convenient to use, the dimming control can be realized through the smart home system simply by connecting the lamp to the power supply and then to the network.

LED driver

And for some individual LED lamps, lamps and so on, does not have the dimming component, theoretically still can adjust the light. From the basic principle, there are three ways of LED dimming, which are linear dimming, PWM dimming and SCR Dimming. Linear dimming has been gradually eliminated because of its low efficiency and poor dimming effect. SCR dimming can be applied to ordinary incandescent lamps and LED lamps, so it can be directly replaced, but its dimming effect on LED lamps is not ideal, so the application is also less; the most widely used, dimming the best performance is PWM dimming.

Color temperature adjustment and color adjustment, in essence, is a separate multi-channel LED brightness. For example, color temperature regulation, is through two dimmers, one is white LED, the other is warm yellow LED, through the brightness of the two LED to create different color temperature, of course, these leds are done together, adjustable temperature light band, you can see white LED and warm yellow LED. Color is RGB three-color LED or RGBW four-color LED with different brightness, essentially three-way or four-way LED brightness adjustment.

There are three common ways dimmer modules can be plugged into smart home systems:

One is to integrate the communication module directly with the dimming driver module, that is, the dimming module and the intelligent control module together, directly through wifi or ZigBee, etc. , intelligent dimmer lamps are essentially of this kind;

The second is 0-10V, dimming drive to receive 0-10V analog control signal to control lamp brightness, this way if you want to access the need to add an intermediate component, to achieve network communication and 0-10V signal conversion;

The third is Dali, pure digital dimming, each lamp has an address, through the pure digital control bus and other ways to achieve the precise control of each lamp, high cost, good performance, mainly for wired control.

Of course, there are other ways to access it, which are relatively niche, so I won't go into too much detail here.

At present, for the smart home access of dimmable lamps, in addition to the smart dimmable lamps that can be directly accessed, it mainly relies on the dimmable modules integrated with intelligent control modules, that is the first kind of above and 0-10V access module, that is, the second kind of above said.

The recently launched light dimming system by AQARA is one of the components mentioned above, such as the integrated intelligent dimming driver, which can directly interface with common LED downlights, spotlights, light strips, etc. , Zigbee 0-10V module, can be connected to a variety of 0-10V dimmer driver, so that dimmer lamps can be greatly improved in the optional range.
