LAMP
Document Type and Number:
WIPO Patent Application WO/2023/080039
Kind Code:
A1
Abstract:
This lamp has a light source (4) provided inside a lamp chamber (7) formed by an outer lens (2) and a housing (3), and a humidity-regulating mechanism (6) for regulating the humidity inside the lamp chamber. An evaporation port (8) that allows the lamp chamber (7) to communicate with the outside is provided to the housing (3). The humidity-regulating mechanism (6) has a movement mechanism for causing a moisture-absorbent material to move to a first position at which the moisture-absorbent material is exposed from the evaporation port (8) toward the lamp chamber (7), and a second position at which the moisture-absorbent material is exposed from the evaporation port (8) toward the outside. The humidity-regulating mechanism (6) is configured such that the size of a space occupied by the humidity-regulating mechanism (6) does not change irrespective of whether the moisture-absorbent material is located at the first position or at the second position.
