AC driven LEDs are rare but popular in certain applications. Designers focus on LEDs because of their advantages like direct, brilliant light, strong color saturation, slim measurements, dynamic lighting scenes and in total all the design possibilities that are thinkable. The only restrictions are made by the heat that needs to be dissipated by surface, natural or forced ventilation and the driver’s measurements. The driver is mostly not slim at all. That is why AC driven LEDs can be a smart consideration.

Conventional LEDs, Modules and Light Engines are driven by DC (direct current) power supplies. The LED characteristics are highly dependent on these components as they control the inrush current, convert the alternate current down to DC voltage and stabilize the current the LEDs are driven with. The efficiency of the system is dependent on the driver too as the power factor is one part in the total sum. Most conventional DC power supplies support LED systems with power factors (PFC) of 0.9 and higher.

The lifetime of LED lighting systems is defined by electronic devises. The LED can last up to 100,000h but if the driver needs a replacement after 50,000h the system is only half worth the maintenance. Without any driver at all the problem is solved completely. Power supplies need space, no matter how small, the driver is mostly bigger than the LED modules and electronic component’s wiring needs space too. Without this item there are not restrictions in design any more than heat dissipation. Designers can release their full creativity.

AC driven LEDs are of advantage concerning design and lifetime options. The more complex the circuit, the higher the possibility of system failure and electrical noise. On the other side, the efficiency of AC driven LED modules is not that high like DC driven ones. The performance achieves 110 lm/W these days which is good compared to other light sources but behind DC driven LEDs with up to 140 lm/W and more. AC driven LEDs are a thinkable substitute in applications like bulb lights, downlights, ceiling lights and industrial lighting systems.

With the holiday season approaching, some people get really excited to celebrate the time of year. For some people, this includes decorations and lighting appropriate for the specific holidays they celebrate, for religious reasons or otherwise. Once the lighting has been set up and is functioning properly, it can be a beautiful display. Setting the lighting up will be fun, but in some cases can pose challenges and require creative solutions.

The Fun of Setting up Lights for the Holidays

Holiday lighting can be a personal project, a time for the whole family to come together as a team, or even a community effort for the whole neighborhood. Think of it as a creative craft project, but rather than something you work on at a kitchen table or work bench, it's the size of the entire house. Some decorations are bought, others are built, and they all have to go up to form a visually appealing end result based on the imagination of whoever is in charge. Beyond the cosmetic appearance, there is a practical nature to the project of getting everything plugged in while keeping the wires discreet and without overpower any circuit line of electric power in your home.

The Draw of Lighting on Circuit Breakers

There are some jobs out there that you can very well do all on your own. But there are others that need the guidance and experience of a certified electrician in Gaithersburg. Considering a renovation or remodel for your home and not sure what you’ll need an expert for? Follow along with the team at Kolb Electric to find out!

It can be tempting to try your hand at electrical work, particularly if you think a job is simple. But at Kolb, our team would really, really recommend that you almost never attempt electrical work on your own.

Why? Primarily because of safety. It can be very easy to get an injury when doing electrical work, even for a professional. But also because a lot of work requires certain certification for the job to be within electrical code, which is a legal matter you don’t want to be on the wrong side of.
