Abstract
A heat sink containing a woolen material is provided for a band-pass filter in a curing lamp. Light having a particular wavelength(s) is transmitted through the band-pass filter and into the heat sink whereas light having other wavelengths is reflected by the band-pass filter. The heat sink absorbs the light transmitted through the band-pass filter and dissipates the heat associated therewith.
