Document Type and Number:
WIPO Patent Application WO/2019/024280
Kind Code:
A1
Abstract:
Disclosed are a lens device, a photography apparatus, and an unmanned aerial vehicle, wherein the lens device is applied to the photography apparatus, and the photography apparatus comprises a host (60). The lens device comprises a lens module (10) assembled at the host (60), a housing (20) fixedly connected to the host (60), and a lens assembly (30) connected to the housing (20) in a sealed manner, wherein the lens assembly (30) is arranged opposite the lens module (10), and a closed accommodation space is formed between the lens assembly (30) and the lens module (10). A closed accommodation space (21) is formed between the lens assembly (30) and the lens module (10), and air in the accommodation space (21) is not circulated with the outside, thus, the water vapour content in the space is constant. When the lens assembly and the lens module are assembled, water vapour condensing on and fogging up the lens assembly can be ameliorated or avoided by means of controlling the water vapour content in the air, thus keeping the imaging effect of the lens module stable.
