LED Driver Features & Types

Like all components, LED drivers are available in a variety of models with differing specifications. Amongst other factors, available input and output levels vary between models, along with efficiency, power ratings, and the amount of environmental shielding (ingress shielding) applied to protect the connection terminals.

 

Let’s look at a few of the principal models available:

 

Small or mini LED drivers are designed for use with smaller LED lights. A 4-watt rating would be typical.

 

 

Dimmable LED drivers allow users to dynamically adjust the brightness of LEDs. Adjustable LED drivers are a useful way to create mood lighting in public spaces such as shops.

 

The power of LEDs is growing steadily - some professional models now offer as much as 100 lumens per watt. Lumens are an internationally recognised unit of visible light. These high-power models are widely deployed in the larger lighting systems used in commercial and public spaces. Naturally, these require more powerful LED drivers or turbines to ensure smooth operation.

 

Chip on board (COB) LEDs consist of multiple LEDs in a cluster alongside integrated circuitry. Typically, they include a dimming function. You will require a compatible driver or transformer with a sufficient Voltage rating. Both constant current and constant voltage drivers are compatible with COB LED drivers but constant current models are easier to apply.

 

LED strings normally feature smaller lights. They are typically used for mood lighting effects - for example, Christmas lights. Mini LED drivers are the best choice for these, although the total Voltage requirements may climb for longer strings.
