Title:
DUSTPROOF AND ANTI-FOGGING STAGE LAMP
Document Type and Number:
WIPO Patent Application WO/2021/147317
Kind Code:
A1
Abstract:
Disclosed is a dustproof and anti-fogging stage lamp, comprising a lamp holder (100), wherein a light source (200) and a light emitting lens (300) are respectively arranged at two ends of the lamp holder (100); a hydrophilic coating is arranged on a side of the light emitting lens (300) close to the light source (200); and an anti-static coating is provided on a side of the light emitting lens (300) away from the light source (200). According to the dustproof and anti-fogging stage lamp, water vapor in the lamp holder (100) tends to be condensed on an inner side of the light emitting lens (300), such that the hydrophilic coating is provided on the side of the light emitting lens (300) close to the light source (200), the height of water drops condensed on the inner side of the light emitting lens (300) is reduced by utilizing the hydrophilic property of the hydrophilic coating, and unnecessary light scattering caused by refraction of the water drops is reduced; and charged dust or charged liquid drops are generally located in the external environment and tend to be attached on an outer side of the light emitting lens (300) with accumulated static electricity, such that the side of the light emitting lens (300) far away from the light source (200) is provided with the anti-static coating to reduce the accumulation of static electricity on a surface of the light emitting lens (300), thereby preventing of the attachment of the charged dust or charged liquid drops and preventing light blocking or light refraction.
