Dimming LED Strip Lights with the Mean Well PWM

‘How do you dim LED Strips?’

This is a common question we receive multiple times a day. Simple 12V LED systems (like the flex strips) can be dimmed, but it requires the right power supply and setup. Through the years working with LED strips there were two options:PWM dimmer in series with LED Strip Lights

  1. Using a PWM dimmer in-series with the LED Strips.
  2. Buying a pricey AC dimmable power supply.

Both options are adequate in providing quality dimming, but still might not be right for everyone. Using a PWM dimmer in-series typically works better from a remote dimmer. Using a PWM wall dimmer requires excessive wiring and limits the load that can be handled. AC dimmable power supplies are great if there is already a common residential dimming setup within the home, otherwise this route can be very expensive.

Mean Well developed a unique AC to DC switching power supply that transmits a PWM style constant voltage output. This is a way to beat the system as the PWM output can be controlled by non-PWM dimmers like our affordable 0-10V dimming control. Let’s see how this power supply works to dim LED strip lights in a way otherwise not possible. Continue reading

Common BMW LED Tail Light Repair: $6 Replacement for bad circuit board

As LED lighting continues to improve and grow in popularity, more and more manufacturers are utilizing them in larger scale products such as household appliances and cars. Unfortunately, many manufacturers take shortcuts when designing these parts, using poorly designed and built electronic components. Not only do these failed parts damage the reputation of LED lighting but they also create short term problems for the owners as they now must deal with partially broken products that could be expensive to fix.

One of these types of issues has been identified in BMW models (2011-Present). The second generation BMW X3 F25 (years 2011-2017), like many other BMW models, added new style features to the high end mid-size SUV. One of these added features was LED lighting within the tail light assembly. Unfortunately, the BMW X3 LED tail lights have become notorious in failing as early as 60,000 miles after purchase. This issue has left many faithful BMW owners frustrated and looking for a solution. Continue reading

Dynamic LED Light Housing: The Interchangeable LED Module

LEDSupply offers many high power LEDs from the likes of top manufacturers such as Cree and Luxeon. These surface mount LEDs are not finished products, rather the light source for whatever lamp or light emitting product you plan to build. These component LEDs are mounted on a 20mm star board—a small aluminum based circuit board (MCPCB). In order to illuminateled-light-kit-parts these LEDs and keep them running safely there are multiple components needed: LED drivers, power supplies, optics, and heatsinks…just to name a few. With multiple working parts, not to mention all the wiring, comes the need to put it all together into a finished product without it looking like a crazy science experiment. That is where dynamic LED housings can come in handy, making for a sleek LED module with multiple purposes. Continue reading

Installing LED Flex Strips: Mounting Techniques

led-strip-adhesive-backingLED flex strips are extremely popular in home lighting applications. LED strip light applications continue to grow because of their ease of use. The low-profile design, flexibility, efficiency and adhesive backing make them a no-brainer for many DIYers looking to put LEDs in their home. Like any other product, the whole is only as good as the parts. A common failure for these strips is that their adhesive backing fails on some surfaces or tends to give way over time. Luckily, here at LEDSupply we have taken feedback and found additional ways to mount these LED strips. Use some of these methods in installing LED strips to enjoy for years to come! Continue reading

Automatic Lighting with Motion Sensor LED Light Strip Module

I work with LED lighting everyday and am still continually amazed at the sheer amount of lumens LEDs can emit. Take for example our new LED Motion Sensor Strip Light, with just a 20″ section and a 8AA battery-pack, this motion activated light boasts as much light as a 40-Watt incandescent bulb; plus it can run over 30+ hours before needing to be recharged. Since it’s wireless, super-bright, battery-powered, custom, inexpensive and activated by motion there are literally tons of lighting applications to consider. But first, lets look at the main components that make-up this module and then look closer at all its benefits, features and applications. Continue reading

LED Strips in Automotive Applications

LED Strip Automotive Applications a Cause for Concern

LEDs on a boatWhen using Led Strips in automotive or boating applications there can be concern about over-voltage and sharp voltage spikes. These are fast, short duration electrical transients in voltage and happen anywhere there is an alternator to charge the battery and other components like fans, solenoids and relays. In a 12V strip application, over-voltage and spikes can deliver too much power to the LEDs. This will lower their output faster over-time and in some cases result in thermal runaway, which ends badly. Given the awesome amount of fun automotive LED strip applications there are (think cars, motorcycles, atv and boats), we have a few easy solutions for you, so you can rest easy and be assured that your voltage stays at 12V and keeps those LED strips running well.

Hard Wired LED Power Sources from Mean Well

When installing LED lighting in or around the home, there will always be a need to switch the available AC line voltage down to a safe direct current (DC) power for the lights. One way of doing this is to hardwire in an AC to DC converter. These switching power sources can be grouped into two main categories: constant current LED drivers and constant voltage power supplies. Learn more about the difference between these two options and discover which type of power your LEDs need here. When LEDSupply became an authorized Mean Well distributor our LED driver and power supply catalog grew significantly. As one of the industry leaders in LED transformers, Mean Well has many options to choose from, whatever your LED application may be. Continue reading

120V LED Light Strips: Long run strips for indoors and out!

led-strip-lightingWith the constant improvement in LED strip lighting, linear lighting applications continue to increase in popularity. LED flex strips have become the standard for adding indirect, accent lighting around your home. These low voltage, 12V strips are used a lot in under cabinet lighting, back-lighting and shelf lighting…a big drawback is that they do not come in long lengths, the longest available single run option being only 16.4 feet (5m). Standard density strips can connect up to 32 feet long but that is still too short for applications like crown and cove lighting, outdoor deck lighting, or any application requiring a long string of lights. Luckily there is an AC powered LED strip that boasts a much heavier duty design that I would have no problem putting in any elements, plus it can run in long lengths all the way up to 150 feet!

How To Choose an LED Power Supply

Whether you are building your own LED fixture, fixing and retrofitting existing fixtures, or purchasing new LED lights, you will need to find the correct power source for your LEDs. You will either need a constant current LED driver or a constant voltage power supply (or a combination of both) in order to make your LEDs work properly. There are many different factors to consider when choosing a power supply for LED lighting. This post will go through those many factors and help you select the right power supply for your LEDs!

12 Volt LED Light Strips: Powering and Wiring

 

LED strip lights have become a quick and efficient answer to providing accent lighting around cool-white-flexible-led-strip-light-non-waterproof-led-ribbon-light-12volt-300leds-5050your home. A relatively low cost option is low voltage, 12 volt LED strip lighting. These discrete strips are sometimes called led ribbon lights or flexible led strips, referring to the ease at which they form to any surface to provide a soft, smooth accent light. Their low 12VDC power input makes them run at an efficient rate while 5050 LEDs keep it running cool and safe to run in tight spaces. All of these factor into what makes 12V LED strips so great for under cabinet lighting, accent lighting, bookshelf lighting, task lighting, cove lighting and so much more. Since they are 12VDC powered they are also popular in car and boat applications. Throughout this post we will go through how to make sure you are powering your LED strips correctly and different ways of wiring your strips to make for the best LED lighting set up. Continue reading
