Controller/Driver Electronics

Since LEDs are electronic devices, they require electronics to monitor and control their performance. Continental specifies the design and layout of the Printed Circuit Boards (PCBs) to match product performance specifications.

The electronics applied to an LED light provides controls to manage the pre-determined electrical power to the LEDs and protect them from any undesirable power surges that could cause damage. The electronics will set the power output to the LEDs at a level to achieve the performance specified in the system design. It may require the conversion of the power from alternating current (AC) to direct current (DC). It may also require the reduction in voltage from 120V to 12V to match system requirements. Filters are used to eliminate the potential for unwanted electrical power surge or spikes in current from power sources. These are some of the basic functions to achieve the desired output and longevity of the LEDs.

Second, there are a number of “smart” functions that can be added to the electronics that can control or drive light behavioral activities. These functions help tailor the light fixture to optimize its performance in an application. These include, but are not limited to an internal clock to determine when a light should come on or go off, the ability to change color and the ability to change brightness.

Through a remote control device, these functions can be changed at any time. The use of multiple LEDs in a product offer opportunities to customize the application of these functions to achieve spectacular lighting effects not easily achieved with traditional light sources.
