Claims (2)

A lighting unit that emits light for operation of street lights and traffic lights;
In the device for preventing condensation of street lights and traffic lights using a ventilation mechanism,
a unit enclosure provided in a shape to protect the lighting unit;
An air circulation unit installed in the unit housing to prevent condensation by generating convection;
In the device for preventing condensation of street lights and traffic lights using a ventilation mechanism,
The air circulation unit,
an air tank installed in the unit enclosure to filter, store, and supply external air;
a tank motor integrally formed at the front end of the air tank to generate air supply force and rotational force;
a supply pipe extending integrally with the air tank to move supplied air;
a compression member inserted along the rotational screw thread 230a formed on the inner circumference of the supply pipe;
a first rotation unit that is inserted into the central portion of the compression member and rotates in an elastic manner;
a plurality of second rotation units spaced apart from each other and inserted along the circumference of the compression member to rotate elastically;
a rotational shaft inserted into the first rotational unit and rotated by rotational force generated by the tank motor to rotate the first rotational unit;
including,
The supply pipe,
a rotation shaft fixing member formed to fix the rotation shaft;
a support frame extending in all directions to support the rotating shaft fixing member at the rear end of the supply pipe;
including,
The compression member,
flow grooves to allow the air supplied from the supply pipe to flow at regular intervals along the edges of the circumference;
protruding grooves at regular intervals along the circumference to insert a plurality of second rotational parts;
a rotating part groove so that the first rotating part is inserted into the central part;
is formed,
The first rotating part,
a first main rotating part having a rotating screw thread 251a to be inserted into the groove of the rotating part of the compression member;
a first sub-rotation unit that is stretchably inserted into the first main rotation unit and has a shaft groove for inserting the rotation shaft in a center portion;
including,
The second rotating part,
a second main rotation unit rotatably engaged with the rotation screw thread 251a of the first main rotation unit;
a plurality of second sub-rotators inserted into the second main rotation unit in an elastic manner and having an insertion protrusion formed at a central portion to be inserted into the protrusion groove;
including,
The air circulation unit,
The rotational shaft rotates by the rotational force of the tank motor, the first rotational part rotates, and at the same time, the plurality of second rotational parts rotate along the rotating screw thread of the first rotational part to move forward and backward,
As the first sub-rotation unit and the second sub-rotation unit move forward and backward under control, the compression member compresses the air supplied from the supply pipe and circulates the air into the unit enclosure to prevent internal condensation. Further comprising, condensation prevention device for street lights and traffic lights using a ventilation mechanism. delete
