Over-temperature protection LED driving power source

Abstract

The invention provides an over-temperature protection LED driving power source. The over-temperature protection LED driving power source comprises a hose, a connecting pipe, an airbag, air jetting holes, an air jetting pipe, a filtering cover, round holes, a filtering screen, a desiccant bag and an air inlet hole; the right end of the connecting pipe is provided with the airbag; the lower end of the hose is installed at the middle of the annular side surface of the connecting pipe; the upper end of the hose passes through the lower end surface of the filtering cover and is connected with the air jetting pipe; the air jetting pipe is arranged at the left side of the filtering screen; and the air jetting holes are formed at the right side of the annular side surface of the air jetting pipe. According to the over-temperature protection LED driving power source of the invention, a dust back-blowing function is additionally realized; the air inlet hole is formed at the right end surface of a shell; the filtering cover is assembled at the right end surface of the shell; the filtering screen is installed at the right side of the interior of the filtering cover; the desiccant bag is assembled at the left side of the interior of the filtering cover; and the round holes are formed at the right end surface of the filtering cover. The over-temperature protection LED driving power source of the invention can filter heat-dissipating air. The over-temperature protection LED driving power source of the invention has the advantages of long service life, high stability and high reliability.

Description

technical field [0001] The invention is an over-temperature protection LED drive power supply, which belongs to the technical field of lighting. Background technique [0002] The LED drive power supply is a voltage converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Usually: the input of the LED drive power supply includes high-voltage power frequency AC (that is, mains power), low-voltage DC, high-voltage DC, low-voltage high-voltage frequency AC (such as the output of an electronic transformer), etc. The output of the LED drive power supply is mostly a constant current source that can change the voltage with the change of the LED forward voltage drop value. [0003] In the prior art, there are still many deficiencies in the LED drive power supply. During the heat dissipation process, the dust and moisture in the air cannot be filtered, causing the dust and moisture to enter the power supply, resulting in short circu...

Problems solved by technology

[0003] In the prior art, there are still many deficiencies in the LED drive power supply. During the heat dissipation process, the dust and moisture in the air cannot be filtered, causing the dust and moisture to enter the power supply, resulting in short circuit or poor heat dissipation; the existing The heat dissipation port of the LED drive power supply cannot be closed automatically when it is not working, and the practicability is not strong; at the same time, the existing LED drive power supply does not have a built-in dust cleaning function, which causes air inflow to be blocked and affects the service life. Temperature protection LED drive power supply to solve the above problems
