Background

Light fixtures used in outdoor, bathroom, etc. environments are directly exposed to locations that may be splashed with rain or domestic water. Generally, a lamp used in such an environment is sufficiently designed to be waterproof at a globe portion or the like, but when the lamp is mounted, it is necessary to peel off a portion of the power supply line and the lamp wire, and to electrically connect the exposed wire core with a connector. Thus, the core of the wire at the joint is exposed, a gap is left between the core and the outer cover, and water vapor can still enter the lamp through the lamp joint.

In addition, when the lamp is alternately opened and closed, the temperature in the lamp changes repeatedly, so that the air pressure in the lamp changes, air pressure difference is formed between the inside and the outside of the lamp, a siphon phenomenon is generated, water is sucked into the lamp through the space between the outer cover of the wire rod and the wire core, and accumulated water and even water mist are formed. The water drops are likely to be condensed on the lens to influence the lighting effect, devices such as the lens and a light source are likely to be corroded to reduce the service life of the lamp, and even the lamp is likely to be short-circuited to influence the electricity utilization safety when the accumulated water is excessive.

In addition, if only the wire core and the outer cover are sealed, although water is difficult to enter the lamp temporarily, when the lamp works, high pressure caused by high temperature inside the lamp still causes damage to devices such as a lens and a light source, and therefore the service life of the lamp is shortened.
