Improve LED Public Lighting Performance by Learning The Basis of Ballast Resistance
Specifying resistors seems easy, but for many uses it is necessary to understand all aspects of the application requirements. This is especially true in newer markets, such as high-power Led Public lighting(CLASSIC).
This article will examine how LEDs work and how to properly bias LEDs for optimal illumination performance. This article will also study the operating characteristics of LEDs to find the optimal topology for the lighting device and how to drive the LEDs in series to drive them more efficiently. It will show the importance of temperature stability in maximizing output, as well as maintaining color rules, increasing reliability and extending service life.
Understanding the principles behind LED-based solid-state lighting biases will show that ballast resistors will be responsible for consuming several watts. To perform this task, you need to use a high-power resistor that may require heat dissipation. This requirement complicates the design but is necessary for optimal operation of the LED.
It is important to show practical solutions along with theoretical examples. For these practical examples, this article will use resistors from resistor manufacturer and supplier Riedon. The main areas that will stand out are UT series wirewound resistors that can consume up to 13W, and a range of PF power films that can dissipate 20W. Alternatives are also available for applications that require heat or surface mounting.
