    摘要: A smoke detector includes a smoke detection chamber containing a white light LED and a light detector. The light detector detects light within at least two distinct optical wavelength bands, and generates respective signals indicative of the intensities of the detected light. An analyzer determines, based on the measured light intensities of the different wavelength bands, whether a dangerous smoke/fire condition is present.
