An LED (Light Emitting Diode) is a solid state device, or
semiconductor, which converts electricity passed through it into
visible light. To maintain the light output, colour, efficiency and
maximise the life of an LED, three factors must be controlled:
1. The manufacturing process and composition of the LED itself
2. Thermal management of the heat generated by the LED
3. The electrical supply to the LED
The driver is the device used to control the electrical supply to the
LED. The majority of luminaires in the Eatons LED ranges require
an LED driver. Some luminaires are supplied complete with the
appropriate driver, whilst others indicate on the product pages if a
driver is needed.
Driver Types
There are essentially two basic types of driver, those supplying a
constant current and those supplying a constant voltage. These
are then subdivided by other capabilities such as dimming or
colour changing.
Within the Eatons range there is a wide selection of drivers
offering different features and characteristics to provide the right
product for the application. There is a choice of constant current or
voltage outputs, different levels of Ingress Protection, Dimming
methods and Colour Changing versions as well as different
physical sizes.
