Know All About Isolated & Non-isolated LED Drivers

Currently in the general LED lighting market, there are non-isolated designs and isolated drivers. Non-isolated designs are limited to dual-insulation products, such as replacements for light bulbs, where the LED and the entire product are integrated and sealed in a non-conductive plastic, so the end-user does not have any risk of electric shock.

The secondary products are all isolated and relatively expensive, but they are essential where the user can access the LEDs and output wiring (usually in the case of LED tube light driver lighting and street lighting applications).

An isolated driver or an electrically isolated LED driver means that the LED can be touched directly without touching the battery. The LED driver power supply without the isolation transformer can still achieve partial mechanical insulation by means of the protective casing, but the LED at this time cannot be directly contacted during operation.

Transformer-based isolated LED driver power supply will be the mainstream

Both isolated and non-isolated LED driver power solutions have advantages and disadvantages.

The industry believes that

1. Class II will be the mainstream because it simplifies LED cooling.

2. Class I or II systems rely on grounding systems and, in most cases, are closely related to the     installation location.

3. Class II is more common and requires two-stage or reinforced isolation, which requires transformer magnetic windings, insulation tapes, and physical isolation.

4. Class I systems require a grounded enclosure and/or mechanical barrier that is not required by the Class II system.

There are several trends that are driving the development of the LED lighting market. The first is the continuous improvement of high-brightness LED efficiency and the emergence of highly efficient high-reliability constant-current LED drive power, followed by global legislation prohibiting incandescent lighting (due to its low efficiency) and the gradual fading out of CFL energy-saving lamps (if broken) If it does, it will emit mercury that is harmful to the environment). The combination of these factors is making LED lighting a long-term trend.

Of course, low system costs (including LEDs, thermal management systems, and LED drivers) are always the driving force for consumers to adopt LED general lighting.

In fact, in many LED lighting products, failure is a common phenomenon, mostly because of the failure of the power supply, not the failure of the LED. It’s providing high efficiency, but they also generate more heat transfer than incandescent or energy-saving lamps.

Since many LED lighting applications are enclosed in a small space, it is difficult to dissipate heat by ventilation. Without careful thermal design, LEDs and power drive circuits can easily degrade or permanently fail due to high temperatures.
