Now led dimmable driver is getting more and more popular, and there are many optional led dimmable driver available in the market, so which led dimmable driver suitable for you? Let’s tell you step by step.

The most optimal led dimmable driver can boost the dimming performance, color rendering, and consistency of a range of indoor and outdoor lighting applications, addressing some of the challenges associated with color and brightness control.

Most led dimmable driver manufacturers agree that once the LED is selected there are four key specifications that LED lighting users need to know—input voltage range, output voltage of the LED string, current, and dimming option—in order to narrow down the list of optimal led dimmable driver for the application.

As a user, you should think these questions of led dimmable driver as below,

What is the input supply voltage range to the led drive circuit?

What is the LED load configuration and characteristics?

What is the min/max LED string voltage?

Is dimming required? If so, by what means: analog, PWM, combination, other?

What (if any) are the fault detection, protection, and reporting requirements?

This goal is to match the customer’s need with the best led dimmable driver. If you consider the question above, you will face the determination of constant current or constant voltage led dimmable driver.

All drivers are either constant current led dimmable driver or constant voltage led dimmable driver, or both. This is one of the important factors you need to consider in your decision making process. This decision will be determined by the LED or module you will be powering, the information for which can be found on the LED’s datasheet.
