The reason external dimmable LED drivers are used is that they can be located away from the light source, often in a more convenient location. They are also useful when upgrading older lighting to LED, or when installing new lighting in a large area where multiple fixtures will be used. If your LED does not have a built-in driver, you will need to use an external driver with a compatible dimmer switch.Įxternal dimmable drivers are used when an internal driver is not suitable or practical. Lighting fixtures with internal dimmable drivers include: The reason internal dimmable LED drivers are used is to provide a space-saving and often more aesthetically pleasing solution, as well as reducing installation costs. Internal drivers cannot be accessed or replaced without potentially nullifying the warranty. To dim an LED with an internal driver, you will need a compatible dimmer switch, and be sure to check that it is indeed dimmable. Many LEDs come with built-in drivers that allow them to be dimmed using one of the many methods available. The driver is either incorporated internally in the product or you have to pair a suitable external driver with the LED fixture or series of fixtures being installed. When dimming lighting, the driver has to be compatible with the control method being used in the room or building. Most LEDs in use today are constant current or constant voltage and require a power supply called a ‘ driver‘ to convert the AC current from a lighting circuit into a low voltage DC current that is suitable for the type of LED chips being used in the fixture. Mains voltage LED AC Current, either at 110V or 230V.However, LED requires careful planning and there are a variety of types to be aware of. LED is now the primary source of lighting and it can be dimmed. The overall light output is reduced by reducing the voltage to the LED or by reducing the reducing the AC current. These days smart phone or tablet apps are popular whilst sophisticated systems integrate wider building control through wall mounted touch screens. How Does Dimming Work?ĭimming works by reducing the amount of power that is supplied to the light source controlled in a number of ways, commonly using a wall mounted dimmer switch. In lighting design, there are two main types of dimmed lighting: active dimming and passive dimming.Īctive is where the power to the light source is actively reduced and there are many ways of doing this, while passive relies on a material that absorbs light to reduce the output. When a lighting fixture or bulb is dimmed, the lumen output of the light source is decreased, lowering the lighting levels in a room.ĭimming can be used for a variety of purposes, such as reducing energy consumption, creating different lighting effects, or extending the life of light bulbs. Dimming is the method of reducing the output of light from an artificial lighting source.
