FUNCTIONAL VERSION Introduction The Feasa Low Light Analyser is an instrument that tests the Color and Intensity of Light Emitting Diodes (LEDs) in a Test Process. It has been specifically designed to test Leds in low light situations such as backlit Switches and Panels. -
Page 6: Important Information For Programmers
FEASA LED ANALYSER LOW LIGHT FUNCTIONAL VERSION IMPORTANT INFORMATION for Programmers set / put Commands The Set / Put commands are used to adjust various settings in the LED Analyser such as Intensity, Exposure and offsets. The Set commands are written to the on-board Flash. -
Page 7: Colour And Saturation
– the greater the amount of white the closer it will be to the center. The Feasa Led Analyser output of Saturation is NOT part of the International System of Units. and is not an absolute or traceable unit of colour measurement. It is part of the Hue Saturation and Relative intensity (HSI) system of describing colour. - Page 8 FEASA LED ANALYSER LOW LIGHT FUNCTIONAL VERSION The RGB and Hue values in Figure 2 show how different Colour LEDs can be identified. SATURATION 100% Green Blue Yellow Orange White See Page 10 Figure 2. The RGB or Hue values are used to identify different Colour LEDs.
-
Page 9: Intensity
FEASA LED ANALYSER LOW LIGHT FUNCTIONAL VERSION Intensity Intensity is a measure of the amount of light being emitted by the LED. The Analyser tests the Intensity of each LED and outputs this value to the Test System. The value is output as a number in the range 0-99,999. -
Page 10: White Led's
FEASA LED ANALYSER LOW LIGHT FUNCTIONAL VERSION White LED's White LED's must be treated differently to coloured LED's when being tested. White is not a colour – it is a mix of all other colours. The three Primary colours Red, Green and Blue will be mixed in approximately equal proportions to display a White colour. - Page 11 64000 56000 Bright LED Figure 5b. Note:- the Relative Intensity Value will depend on the Range selected. Note:- Feasa recommends selecting a Capture Range to achieve Relative Intensity Reading of 55K to 85K for the best results.
