As specializing, described sealed guide post is for being provided with externally threaded hollow stud.

As improvement, the part of described sealed guide post in first housing and second housing is equipped with the nut that matches with the sealed guide post.

As improvement, described first back cover and fore shell are equipped with the tapped installing hole that matches with the sealed guide post.

As improvement, the wire column installing hole edge of described heat abstractor is provided with sealed adhesive slot; In sealed adhesive slot, be provided with O-ring seal.

As further improvement, the wire column installing hole of described heat abstractor is provided with the internal thread that matches with the external screw thread of sealed guide post.

Compared with prior art, the utility model has been set up the sealed guide post, and the power supply of LED electronic devices and components and the lead of signal in the LED lamp pearl group and second housing in connection first housing are arranged in the sealed guide post.Advantage of the present utility model exists: owing to be located at wire column installing hole and the O-ring seal that sealed guide post between first housing and second housing is furnished with heat abstractor, this structure has solved the waterproof difficult problem that split-type structural brings, reached the purpose of three layers of waterproof, guarantee to pass the safety of the circuit lead of sealed guide post inside, more guaranteed the water resistance of housing.
