Abstract

The invention relates to the technical scheme of pressure balance devices, and discloses a pressure balance device and a lamp with the pressure balance device. The pressure balance device comprises a balance component and a mounting component, wherein when pressure of an inner cavity of the lamp is smaller than external pressure of the lamp, the balance component carries out automatic adjustment, and the mounting component is fixed to a lamp shell. The mounting component comprises a main body and a casing shell, wherein the main body is provided with a penetrating through hole, and an opening is formed in one end of the casing shell. An air guide groove for being communicated with the casing shell is formed in the hole wall of the outer end of the through hole, and the balance component comprises a spring, a sliding block and a sealing piece; and the spring, the sliding block and the sealing piece are arranged in the through hole in sequence. The invention further provides the lamp. The lamp comprises a shell body and a light-emitting component which is fixedly arranged in the shell body. A mounting hole is formed in the shell body, and the pressure balance device is fixedly arranged on the mounting hole. According to the device, internal pressure and external pressure of the cavity of the lamp are balanced, and the suck-back phenomenon is avoided; the service life of the lamp is prolonged; and the pressure balance device is simple in structure and good in sealing performance, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of an air pressure balance structure, in particular to an air pressure balance device and a lamp using the air pressure balance device. Background technique [0002] Considering factors such as dustproof and waterproof, the inner cavity of many lamps often adopts a sealed design. Due to factors such as self-heating of the bulb in the inner cavity of the lamp, the temperature of the inner cavity of the lamp rises, and at the same time, the air inside is heated and expands. This will reduce the service life of the bulb; when the bulb stops working, the temperature of the inner cavity of the lamp will drop, and the inner cavity of the lamp will be in a negative pressure state relative to the outside, that is, the air pressure outside the lamp is higher than the air pressure in the cavity of the lamp, which will easily lead to Suckback phenomenon, at this time, water vapor and dust in the environment are easily ...
