Abstract
The invention discloses a device capable of keeping balance of internal and external pressure of a lamp. A pressure regulating device of the device is located on the inner portion or the outer wall of a lamp casing (1). A method keeping balance of the internal and external pressure of the lamp is further disclosed. Firstly, an air bag (2) is installed in the lamp casing (1), and an inlet of the air bag (2) is communicated with the outer portion of the lamp casing (1). When a lamp tube (5) is powered on and gives out light, air in a cavity of the lamp casing (1) is heated by heat of the lamp tube (5) to expand so as to extrude the air bag (2) and discharge air in the air bag (2), and pressure balance is kept. After a lamp tube (5) is powered off, the air in the cavity of the lamp casing (1) is shrunk due to cooling, and the air bag (2) expands due to suction of external air so as to keep pressure balance. The method and device capable of keeping balance of the internal and external pressure of the lamp can keep pressure balance in the lamp, improves tightness of the lamp, and reduces maintenance cost.
