PROTECTIVE DEVICE FOR A GROUND-DEPOSITED LIGHT.

摘要

Protection device for a tag. Such a tag, for example a signal light used in airports, generally comprises a housing (2) having a cover (3) provided with an opening (5) for the passage of light rays emitted by a lamp (4) placed inside the housing. To protect the lamp from rain, snow and dust, the opening is closed by a translucent material. To protect the translucent material of mechanical influences, grains of a material stronger than the translucent material are partially embedded in said translucent material.
