Power Source

The most common source for powering LED lighting systems is the traditional on-grid electric utility. Expanding use of LEDs as a substitution for incandescent light sources has the potential for significant energy savings and indirectly, a cleaner environment.

Conversion of power from AC to DC is required. Depending on the application, a light fixture may also require a step down to a 12V system. If not integrated into the light source electronics, a separate device may be required in the power line.

Alternative energy sources such as solar or wind can be a viable alternative source of power. These sources typically have intermittent power generation capability requiring a battery to store energy for later use or connect to an on-grid utility as a back-up.

Since a battery already stores its power as DC current, conversion would not be required to power LED lighting. The reduced energy requirement to power a comparable incandescent light source makes the LED a very attractive option when alternative powers sources are considered in lighting applications. Additional electronic functions can be efficiently integrated into the lighting PCB to accommodate battery power management requirements, as required.

Continental has experience to assess the value of both on-grid and alternative energy power source use in LED lighting applications.
