8 pilnīgi dažādi veidi, kā aptumšot LED lentes


Triac_dimmer_led_strip_lightJa vēlaties uzzināt vairāk par aptumšojošiem LED slokšņu lukturiem un aptumšojamiem draiveriem, šis raksts ir paredzēts jums. Ir viegli tikt pārņemtam ar milzīgo informācijas apjomu internetā. Lai to sarežģītu, liela daļa no tiem ir nepareizi, novecojuši vai vienkārši sajaukti. Un vēl ļaunāk ir tas, ka gandrīz viss paredz, ka jums jau ir zināmas zināšanas un pieredze elektronikā.

In this article we'll cover the many different ways you can dim your LED light strips, including TRIAC and pulse-width modulation (PWM) dimmers. BASICS Why do we need a method to dim our LEDs? Even if your LEDs were designed for outdoor or commercial use, it doesn't mean that you can use them like that all the time. If you're planning a party, for example, it'd be nice to increase or reduce the brightness of your lighting as needed. The same goes for an office environment: some people work better in bright conditions and thrive during daytime-like levels of illumination, while others can't concentrate unless there's enough subdued light.

Aptumšojošo LED slokšņu apgaismojuma priekšrocības

Aptumšojams apgaismojums sniedz iespēju pielāgot apgaismojumu jūsu konkrētajai darbībai. Varat vēlēties spilgtu gaismu kā uzdevumu apgaismojumu, bet vāju, relaksējošu gaismu vakara pusdienu laikā.

Aptumšošana tiek plaši izmantota arī komerciālās un rūpnieciskās telpās. Piemēram, regulējams apgaismojums nodrošina jūsu biroja telpu elastību. Tas nodrošina optimālu apgaismojumu, kas atbilst jūsu darbinieku vajadzībām.

Tas ir īpaši svarīgi, ja vienā telpā ir vairākas darbstacijas. Spējot pielāgot katras galda lampas spilgtumu, jūs varat nodrošināt, ka katram darbiniekam darba laikā ir pietiekami daudz gaismas, neliekot citiem justies neērti vai nepietiekami apgaismotiem.

1. Vai visas LED sloksnes ir aptumšojamas?

Atbilde ir jā, visi lentes apgaismojumi ir aptumšojami, spilgtumu var regulēt, nodrošinot saderīgu līdzstrāvas signālu. LED sloksnes gaismai ir divi veidi, kā to aptumšot: viens ir izmantot dimmer kontrolleri un otrs ir izmantot PWM vadības metodi. Pirmais veids ir izmantot reostata regulatoru, kas tieši regulē barošanas avota spriegumu. Otrs veids ir izmantot PWM vadības metodi (impulsa platuma modulāciju), kas tieši kontrolē katra impulsa darba ciklu.

2. Faktori, kas jāņem vērā, izvēloties aptumšošanas metodi

Izvēloties aptumšošanas metodi, jāņem vērā šādi faktori:

Jūsu projekta lielums: Jūsu projekta lielums ir svarīgs faktors, kas noteiks izvēlētās aptumšošanas sistēmas veidu. Jo lielāks ir jūsu projekts, jo lielāka iespēja, ka jums būs nepieciešama īpaša shēma, lai kontrolētu tā apgaismojuma elementus. Turklāt, ja plānojat vienā ķēdē uzstādīt vairākus dažādu veidu apgaismojumu (piemēram, kvēlspuldzes un dienasgaismas spuldzes), iespējams, vēlēsities apsvērt cita veida dimmeru izmantošanu.

Jūsu izvēlētais reostata interfeisa veids: Daži cilvēki dod priekšroku pārslēgšanas slēdzim, savukārt citi dod priekšroku rotācijas pogai. Ja meklējat ērtības un vienkāršību, vislabāk ir izvēlēties gaismas regulatoru ar rotējošu pogu, jo tas ļauj lietotājiem pielāgot gaismas intensitāti, vienkārši pagriežot plaukstas locītavu. No otras puses, pārslēgšanas slēdžus ir vieglāk uzstādīt nekā grozāmās pogas, jo tiem nepieciešams mazāk vadu un savienojumu.

Jūsu budžets: Dimmeri ir pieejami dažādos cenu diapazonos; tādēļ ir svarīgi nodrošināt, lai jūs iegūtu tādu, kas atbilst jūsu vajadzībām par pieņemamu cenu.

3, dažādas aptumšošanas metodes

Since LED strip lights are now becoming increasingly popular, many people are curious about them and want to know more about the different dimming methods for LED strip lights. Today, we will introduce some dimming methods for LED strip lights.

3.1 Triac Dimming

Most wall dimmers available today use the TRIAC dimming signal. You’ll need to find a dimmable power supply for these wall dimmers.

  • The TRIAC dimmable power supply has two functions:
  • Change 120V/220V AC to 12/24V DC signal for led strip lights.
    Interpret dimming signals produced by the Triac wall dimmer and then translate that into the LED strip’s output.

You’ll need to connect the TRIAC dimmer to the dimmable power supply, then link the power supply’s output to the LED strip.

To avoid voltage drops, ensure that your power unit stays close to your strip lights. Here are the two types of Triac dimming options.

3.2 Low-Voltage PWM Dimming

PWM, or “pulse width modulation” is a dimming method used for many LED strip applications. PMW is a digital signal that “talks” to your strip’s power supply to adjust brightness. You can install a DC PWM dimmer between a standard, non-dimmable power supply, and the LED strip. It usually has a turn dial (potentiometer) that adjusts the LED strip brightness. The power supply can be any standard DC power unit and does not need to be dimmable.

Compared to TRIAC dimmable power supplies, these cost cheaper and are readily available. This simple circuit design works well for portable installations where you don’t have to build a dimmer into a wall. DC PWM dimmers are very simple to assemble, easily connecting to the power supply and LED strip.

3.3 RF Dimming

RF or “radio frequency” dimming provides a remote way to adjust your strip brightness.

Unlike the wired inline LED dimmers, you can dim the led strip by remote control, the distance can get as far as 20 meters in diameter.

3.4 WIFI Dimming

A smart dimmer allows you to control your LEDs remotely via a WiFi connection. When setting up a “smart” home or office lighting system, these dimmers are necessary.

You can operate the dimming by using a mobile app. This feature lets you adjust brightness using Alexa or Google Assistant voice controls.

3.5 0/1-10V Dimming

0-10V dimming lets you adjust brightness by altering DC voltage powering your strips.

It can vary voltage between zero and ten volts – zero being “off” and ten at 100% brightness output.

3.5 DALI Dimming

DALI dimming is a step further from the 0-10V system. Like the 0-10V, this dimmer allows you to adjust many LED strips over a wide area using a central controller.

This method also allows individual users to adjust brightness for specific zones using smaller LED dimmers.

3.6 DMX Dimming

“DMX 512” also works by regulating voltage in the transformer to reduce brightness.

Despite being an old dimming method, DMX is still used today. Applications include large-scale installations, such as concerts, theatres, and other performance venue lighting. This method allows for independent control of different areas of the lighting project. It can run up to 512 DMX receivers, also called channels.

There are two ways to wire this dimming system: daisy-chaining and splitting.

The Daisy Chain method requires connecting the wires of each fixture from a loop of the previous one. By wiring this way, you’ll get a line of fixtures that connects to the receiver, decoder, and console of the DMX system. It has a limitation, though. You won’t connect more than 32 fixtures in one chain. Going over this limit will hinder the signal strength required for DMX communication.
DMX splitting is needed if you need to connect more than 32 fixtures. Splitting allows you to expand the communication network by duplicating the DMX output many times.

Regarding LED lighting systems, you may be confused about the terms “controller” and “dimmer.” Simply put, both terms mean the same thing. Both devices allow you to manipulate the settings and brightness of your installation.

Controllers are often used to manage multiple lights at once, while dimmers can simply turn lights on and off.

A controller is a device that allows users to change the color temperature of a light installation with a touch of a button or remote control. Controllers have become increasingly popular in recent years as more people are looking for ways to customize their homes with unique colors and effects. LEDs can be controlled using software that allows users to save and recall presets for different moods or occasions.

Dimmers are devices that allow users to adjust the intensity level of light sources like incandescent bulbs or fluorescents by turning them up or down manually. They work by altering an electrical signal from its source so that more current flows through it when turned up — making it brighter — while decreasing current flow when turned down — making it dimmer.

Secinājums:

Reading through this article should have given you an excellent idea of what dimming LED lentes gaismas and drivers are all about. LED light has finally entered the mainstream for home illumination, but there are still a lot of people who don't know much about them. It's important to learn as much as you can so that you can make informed decisions when there's no one else around to rely on.
