ABSTRACT:
A humidifier comprising an electric lamp, a protector in the form of a dome-shaped member surrounding the glass bulb of the electric lamp, an evaporation layer made of capillary substance closely contacted with the outer surface of the protector to cover the same, and a water-holding saucer for immersing a portion of the evaporation layer in water or a tightly closed tank having a water supply port at the lower end thereof which communicates with the outer surface of the evaporation layer in sealed relation to the outside. By making the protector of light transmitting material, the humidifier can be used also as an all-night light. The evaporation layer is surrounded with an ornamental cover having water vapor outlets.
