The light fitting having a closed lamp house in which a lamp bulb is displayed is provided with a water-proof breather comprising a cylinder (22) extending from the back of the housing (20) rearwardly and having an air-path communicating with a the lamp house and the atmosphere through a mazy passage, and a cap (44) fitted onto the cylinder. The outlet (46) of the air-path is so formed as to open in the lower outer circumference of the cylinder (22). Therefore, the cylinder provides for both breathing and water-proofing functions. Rain water can be perfectly blocked from entering the light assembly. And since the dimensions of the water-proof breather only depends upon the outside dimensions of the cylinder, the lighting fitting with the water-proof breather can be installed in a minimum space. |
