Abstract
The present invention discloses a lamp, comprising: an optical cover; a cap for connecting to electrical power; a tubular housing comprising an upper end connected to the optical cover hermetically, a lower end connected to the cap, and at least one vent opening located at a lower portion of the tubular housing; an air flow path inside the tubular housing for communicating an inner surface of the optical cover and the at least one vent opening; and a light source module and a driving module connected to the light source module inside the tubular housing. The present invention also discloses a lighting fixture comprising the above lamp and a lamp holder. The lamp and lighting fixture of the present invention are water resistant. When the gas inside the lamp causes the internal pressure to change due to expanding with heat and contracting with cold, the hermetically connected portions of the lamp are not easy to be damaged.
