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.
