Ballast = Control gear for LED - dimmable

An electronic ballast (EB) is known from the fluorescent tubes / energy saving lamps technology and had the task of ignition of the discharge lamps. That was yesterday.

Today, we generally understand this to mean an upstream device for operating LEDs. However, a closer distinction must be made here:

1.LED control gear as constant current source/driver for currents of e.g. 350mA/700mA etc. (mostly LED recessed spots, LED panels)
2.LED control gear as constant voltage power supply with DC voltage values of 12V/24V etc. (mostly LED strips/LED modules)
3.LED ballast as transformer with 12V AC voltage for operation of e.g. 12V LED retrofit lamps (GU5.3, GU4, ..)

This depends on the type of LED technology used.

If the ballast LED should be dimmable, so we offer various control options such as DALI, 1-10V, touch dimming, Triac, but wireless solutions such as Casambi.

Electronic LED ballast and what we mean by it

A ballast is generally understood to be an operating unit that is connected upstream of another module (e.g. LED module or fluorescent tube). Without further specification of the function. These differ among other things in

LED control gear as Conventional Ballast:

Conventional ballast equipped with reactors, transformers, etc. Often known in connection with operation of fluorescent lamps. High losses.

LED control gear as Electronic Ballast:

Electronic ballast, does not require heavy chokes. The input voltage is rectified and converted back into AC voltage of higher frequency. This can then be transmitted with small transformers and low loss. Low-loss control of the output variables is also possible via the clocking ratio (PWM).
Disadvantage: Conventional ECGs usually require a minimum load at the output and are the reason why, when converting to e.g. LED lamps, these suddenly no longer work and then have to be replaced by a special LED ECG, often known as an LED driver or LED transformer.

Ballast or control gear for LED:
Are therefore LED power supplies that are connected upstream of an LED module. The term does not explain whether this is a constant voltage source (for e.g. LED strips), or a constant current source for direct operation of LEDs or LED boards.

This product category does not distinguish between the different types, but represented all devices that deserve the name LED ballast or electronic ballast.

However, the following tabular link overview helps to make the desired preselection via the stored filter functions, or allows a refinement/adjustment of the selected filter (e.g. power range, dimming technology, etc.).
