How do I choose the right LED?
In order to choose the right LED for your product or application, you should have a general understanding and knowledge of the different types of LEDs, their typical applications, and their differences in electrical, physical, optical and thermal characteristics. There are many different types and brands of LEDs on the market today and finding the LED that best suits your particular project’s requirements is essential for achieving the maximum performance, longevity and overall success of your LED product or application.
The first consideration when choosing an LED is to determine if a particular wavelength or color is desired for the application. Determining a specific color range (wavelength) or temperature range (degrees kelvin) of light to be used will significantly narrow the range of available LEDs that are suitable, and that can be considered for the application.
Next, the type of available power and drivability of the LED needs to be determined. LEDs of different wavelenght (color) and type have different power requirements, electrical charcteristics and thermal management requirements. The type of available power is a major factor in determining the best LED or LED circuit configuration for the application. In higher voltage applications, it may be more suitable to use many smaller LEDs, in place of one or two larger LEDs, to reduce the amout of power and heat that needs to be regulated.
Refer to the LED manufacturers’ specifacation documentation for information on electrical, physical, optical and thermal charcteristics in order to become familiar with the LEDs that are being considered for the application, or contact LuxDrive Support for more information on how to choose the right LED and driver for the job.
