A vehicle lampis provided with: a ventilating unitthat is provided with a first openingof a closed case, prevents entry of liquids and solids to an inside space S within the case, and allows circulation of air between the inside space S and an outside space of the vehicle lamp; and a dehumidifying unitthat is provided in a second openingof the casedifferent in position from the first openingand has an electrolysis dehumidifying element for discharging water vapor in the inside space S to the outside of the vehicle lampby electrolysis. Thus, a dehumidifying device and a lamp that can rapidly discharge water vapor that has entered the inside of a housing to the outside of the housing can be provided.

Dehumidifying device and lamp

The present invention relates to an organic electroluminescent device comprising a substrate, an organic electroluminescent element, and a photocatalyst layer, wherein the organic electroluminescent element includes: a first conductive layer provided on the substrate; an organic electroluminescent layer provided on the first conductive layer; and a second conductive layer provided on the organic electroluminescent layer, wherein the photocatalyst layer covers all or part of a light-emitting region of the organic electroluminescent element, and contains a photocatalyst and a co-catalyst, and wherein an absolute value of the difference (|R1&#x2212;R2|) between the refractive index (R1) of the photocatalyst and the refractive index (R2) of the co-catalyst at a wavelength of 589 nm is 0 to 0.35.
