Many lighting designers use LED strips as one of the elements of indoor and outdoor lighting design. LED strips that support dimming are preferred. Because dimmable LED strip lighting options can enhance lighting design. While saving energy, the brightness of LED strips can be adjusted in time according to changes in time and environment.
How to Dimmable LED Strip Lights?
To dimmable the brightness of the LED strip. First, we need to make sure that the LED strips you purchased support dimming. More details, pls check How to Choose the Perfect Flexible LED Strip Lights?
In fact, we want to adjust the brightness of LED strips to create a softer atmosphere for the space and save energy. If you want to adjust the brightness of LED strips. You can refer to the following methods to see which one is most convenient for you.
Use a dimmer
- When you have purchased a dimmable LED light strip, you will need to purchase a dimmer.
- Make sure the dimmer is compatible with the voltage and power of the LED strip.
Use a PWM dimming controller
- PWM controller is also commonly used, which can quickly switch the power supply of LED strip to adjust the brightness.
- It does not change the voltage, but adjusts the working time of LED strip.
Smart Dimming
- With a smart light control system, you can adjust the brightness of the LED light strip through a mobile phone app or voice assistant.
- But this also requires the purchase of a compatible controller, which you can set up and control through a mobile phone app.
Why Can’t Some LED Strip Lights be Dimmed?
All of our LED strips are dimmable. However, some LED strips on the market are not dimmable. Of course, you may have purchased LED strips that support dimming. Why can’t LED strip lights be dimmable?
LED strip circuit does not support dimming
The LED strip’s driving circuit determines the stability of its current and voltage. Some LED strips use driving circuits that are not designed to regulate current or voltage, so they cannot be dimmed.
With constant current power supply
If the LED strip uses a constant current power supply, adjusting the voltage or current will not affect the brightness of the strip. Therefore, such LED strips are usually not dimmed using ordinary dimmers. If you need choose the power supply, pls read How to Choose a Power Supply for LED Strips
Insufficient dimmer compatibility
Not all dimmers are suitable for all types of LED strips. Some LED strips may require specific types of dimmers, such as pulse width modulation (PWM) dimmers, while other dimmers cannot effectively adjust the brightness of these strips.
Low-quality LED strips
Low-quality LED strips may not be designed and manufactured with dimming in mind. Because the cost of such strips is low, the driving circuit may not be complex or stable enough to support dimming.
Limitations of LED chips
Some LED chips are simple in design and only support switching operations, so they do not support dimming. These chips cannot adjust the brightness proportionally when the voltage or current changes, resulting in the inability to dim.
Summary
Dimmable the brightness of LED strip can not only create an ideal atmosphere for the space, but also save energy and extend the use time of the light strips. But first make sure that your LED light strip supports dimming, and then use the appropriate dimmer, PWM controller, or smart dimming device to effectively adjust the brightness of the LED tape. When adjusting the brightness of the light strip, be sure to ensure the compatibility of all devices to avoid uneven brightness, flickering, or damage to the light strip.
