Waterproof shell structure capable of balancing internal and external pressure and LED (Light Emitting Diode) driving power supply

The invention relates to the field of LED driving power supplies, and in particular relates to a waterproof shell structure capable of balancing internal and external pressure and an LED driving power supply. The waterproof shell structure comprises waterproof side covers and a shell with through holes at two ends; and the waterproof side covers are respectively arranged over the through holes at two ends of the shell. By applying the technical scheme in the embodiment, the waterproof effect is realized by combining the waterproof side cover with the shell; the waterproof side cover comprises a cover plate and a waterproof gasket, which are mutually laminated to form a cavity; the waterproof gasket is provided with a groove and a bump; in the same way, when the driving power supply generates high temperature, positive pressure is generated in the driving power supply; the bump of the waterproof gasket can be concave downwardly; the cavity is deformed, such that buffering of positive pressure is realized; when the driving power supply stops working, the cavity can be reset or kept in the present state, such that generation of negative pressure can be prevented; because positive pressure and negative pressure are inhibited, water or water vapour cannot enter the power supply; therefore, the sealing property is higher; and the service lifetime is longer.
