Crest lampshade has been made into integration above the upper shell, lampshade sets tapered crest structure, be easy to dust or Dropped down onto under rainwater at grid；Its top of the upper shell is provided with circuit board, and is connect with the lamp plate of circuit board electrical connection and power supply Head；The power connection is connected to civil power through isolation cabin, and power connection and upper stressed plate, lower stress plate and upper limit ring, The junction of lower limit ring is provided with waterproof nozzle, prevents dust or water droplet from entering from junction.

As preferred embodiment, its outside of the upper shell has been made into integration outer barrel, improves overall stability And firmness；The upper shell and its junction of outer barrel are provided with grid, and the dust or rainwater fallen from crest lampshade can be from Fallen at grid, prevent the accumulation of dust and rainwater.

Further, the upper stressed plate and upper sealing ring along upper shell its inwall be move upwardly until upper stressed plate with Its lower surface of upper limit ring is bonded.

Further, the lower stress plate and lower sealing ring moved down along lower house its inwall until lower stress plate with Its upper surface of lower limit ring is bonded.

As preferred embodiment, radiating fin is installed at its outer wall of the upper shell, accelerates radiating.

The utility model compared with prior art, water proof and dust proof underground lamp of the present utility model so that air bag can be filled out Full of whole isolation cabin, leave no gaps, improve water resistance；By setting upper sealing ring and lower sealing ring so that in isolation cabin Sealing space is formed, effectively prevents dust or water droplet from entering from lower house in upper shell；Power connection and upper stressed plate, lower stress Plate and upper limit ring, the junction of lower limit ring are provided with waterproof nozzle, prevent dust or water droplet from entering from junction；Crest is set Lampshade and grid, it is easy to dust and water droplet to fall.
