Are all drivers dimmable?

Are all drivers dimmable?

Are all drivers dimmable?

Both constant-current and constant-voltage LEDs and drivers can be made with a dimming capability, though both LEDs and drivers must specify that they are dimmable on the product datasheet for that assertion to be made. If the specs don't mention dimming at all, it is safe to assume that the product is not dimmable.

What is constant-current driver?

A constant current LED driver is an LED power supply that regulates the current flowing through an LED array so as to maintain a desired level of light output. ... It provides accurate output current control regardless of the supply-voltage fluctuations and the changes in other operating conditions.

Are LED driver dimmable?

Dimmable LED drivers allow you to easily adjust the brightness of your LED lights. Our mains dimmable drivers, also known as TRIAC can be used to dim LED tape along with an LED compatible dimmer switch or home automation system.

What are dimmable drivers?

Dimmable drivers offer superior dimming and control to inexpensive PWM dimmers that install on the low voltage (12V or 24V DC) side of the circuit. They're a permanent and elegant solution that keep wires hidden away inside your walls, and dimming control where you expect it - right at the switch.

Do all LED lights need a driver?

Because LEDs require a constant DC of 12v or 24v, LED drivers are required in all LED systems (except those which are specifically developed to be controlled by mains voltage power supplies such as mains voltage tape or LED bulbs).

What causes LED drivers to fail?

It is very rare that agood quality LED driver fails because of a manufacturing fault. In most cases the failure is caused by a problem with the installation, or there are some environmental factors at play. ... You should also make sure that there are not too many lights on the output of the LED driver.

Are LED drivers constant current?

LEDs are constant current devices with a forward voltage drop. This means the voltage supply must exceed that drop in order to allow current to flow, and by controlling the current, you control the intensity.

Can constant current LEDs be dimmed?

Although both constant-current and constant-voltage drivers can be made with a dimming feature, not all LEDs are dimmable — and the ones that are capable of dimming must be used with the proper dimming technology (e.g., PWM or CCR).

When do you need constant current LED drivers?

When your LED light engine needs constant current drive and control as part of the assembly, our constant current LED drivers are the appropriate LED driver solutions. We maintain a broad selection of stocked LED drivers.

Which is an example of a constant voltage driver?

Constant Voltage Drivers switch this alternating current voltage (VAC) to a low direct current voltage (VDC). The driver will always maintain a constant voltage no matter what kind of current load is put on it. An example of a constant voltage power supply is below in the Mean Well LPV-60-12.

Which is better constant current or constant voltage for LEDs?

Constant current and Constant voltage drivers are both viable options for a power supply for LED light sources, what differs is the way in which they deliver the power. LED drivers are the driving force that provides and regulates the necessary power to make sure the LEDs operate in a safe and consistent manner.

What kind of drivers are used for LEDs?

Constant voltage drivers are designed for a single direct current (DC) output voltage. Most common constant voltage drivers (or Power Supplies) are 12VDC or 24VDC. An LED light that is rated for constant voltage usually specifies the amount of input voltage it needs to operate correctly.
