Here is a good reference for color space conversions:
Once you understand the basics of color spaces and converting between them, writing a short function to do a conversion from sRGB to Lab should be quite easy.

You can find "book formulas" here: http://www.easyrgb.com/index.php?X=MATH First go from RGB to XYZ, then go from XYZ to Lab.
