Abstract
The present invention relates to an outdoor lamp with an improved watertight mechanism. Its peculiar watertight structure is formed by a lower-cap and an upper-cap, wherein a slope shaped on an anti-water rim of the upper-cap to facilitate rainwater slipping, out of the slope and gravity, directly to the ground. A convex bottom is further formed on the anti-water rim of the upper-cap causing rainwater, being unable to flow inwards cross the convex, to fall directly to the ground, thereby preventing rainwater from streaming to the lower-cap. Combining the slope and convex thereof, rainwater flowing into a joint surface thereby being reduced significantly. Additionally, the joint surface is formed with a two-step structure to curtail capillarity, thereby minimizing rainwater permeating inside to damage the lamp.
Claims6
An outdoor water tight lamp comprising:
- a) an upper cap having an upper cap sealing rim having:
- i) an exterior sloped surface protruding outwardly from an outer periphery thereof;
- ii) an upper cap joint surface located around an inner periphery thereof;
- and
- iii) a convex portion located between the exterior sloped surface and the upper cap joint surface;
- b) a lower cap having an lower cap sealing rim having a lower cap joint surface located around an inner periphery thereof and engaging the upper cap joint surface and creating a water tight seal there between;
- and
- c) a lamp base connected to the upper cap and the lower cap and located there between.
