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.
Claims27
A lamp light trap and heat transfer apparatus comprising:
- a light source adapted to radiate light having a plurality of wavelengths including light having a wavelength in a first range and a wavelength outside of the first range;
- a band-pass filter positioned in the path of at least some of the light which the light source is adapted to radiate, the band-pass filter being adapted to reflect light having wavelengths in the first range and to transmit light having wavelengths outside of said first range;
- a heat sink provided proximate the band-pass filter, wherein the heat sink is formed of a woolen material adapted to absorb the light transmitted by the band-pass filter.
A method of irradiating an object with light having a wavelength in a first range, the method comprising the steps of:
- generating light having a plurality of wavelengths including light having a wavelength in a first range and a wavelength outside of the first range;
- filtering the light so that light having wavelengths in the first range is directed toward an object to be cured and light having wavelengths outside of the first range is not directed to the object;
- absorbing the light having wavelengths outside of the first range by a heat sink comprising a woolen material;
- dissipating heat generated when the light having wavelengths outside of the first range is absorbed by the heat sink;
- and
- irradiating the object with the light having a wavelength in the first range.
