LED drive power supply with overheating protective function

Abstract

The invention discloses an LED drive power supply with an overheating protective function. The LED drive power supply comprises an LED drive power supply shell, wherein the top of the inner part of the LED drive power supply shell is fixedly connected with a heat dissipating box through a bolt; a gasbag is arranged inside the heat dissipating box; a gas tube is mounted on the outer wall of one side of the gasbag; one end, away from the gasbag, of the gas tube is equipped with a one-way valve; the bottom of the heat dissipating box is embedded with a heat absorbing plate; the position, close toone side of the gas bag, of the top of the inner part of the LED drive power supply shell is fixedly connected with a fan box; and a fan is fixedly connected on the inner wall of one side of the fanbox through a bolt. According to the LED drive power supply disclosed by the invention, the gasbag, the heat dissipating box, the heat absorbing plate, the gas tube and the one-way valve are arranged;in use, on one hand, the problems that electric energy is consumed as electric heat dissipation is adopted, mechanical faults are more and energy conservation and environment protection are not achieved are avoided through breathing type heat dissipation of the gasbag, on the other hand, the problem that the LED drive power supply is damaged as water leakage is easily caused by water-cooling heat-dissipating is avoided.

Description

technical field [0001] The invention belongs to the technical field of LED driving power supply, and in particular relates to an LED driving power supply with overheat protection function. Background technique [0002] LED drive power supply is a power converter that converts the power supply into a specific voltage and current to drive LED to emit light. Usually, the input of LED drive power supply includes high-voltage power frequency AC, low-voltage DC, high-voltage DC, and low-voltage high-frequency AC. [0003] In the Chinese patent with the patent number CN201720010529.0, a LED drive power supply with overheat protection function is mentioned. By increasing the air flow inside the LED drive power supply box, a good heat dissipation effect can be achieved to prevent the LED drive power supply from being overheated and causing The service life of the LED driving power supply is shortened. The water cooling device can effectively cool down the temperature of the LED drivi...
