LED Selector Guide
LED Design Selector
PI's LED Design Selector allows engineers to enter selection criteria and drill down to the best choice from Power Integrations' library of reference designs for LED lighting. The LED Design Selector lists designs according to three major areas of application: residential, commercial, and industrial. For each list, users can sort data and filter results using different parameters.
Alternately, PI has added an LED Bulb Design Selector. This tool lets design engineers choose from images of the most common types of light bulb or lighting application and then view a list of appropriate designs. |
