Problems solved by technology

[0002] At present, in the existing technology, the outdoor lamps and lanterns are mainly sealed and waterproof for the components of the shell. However, outdoor lamps experience temperature changes and power-on heating in the use environment, and the internal air pressure of the lamps often changes, resulting in pressure that repeatedly squeezes the shell and damages the structure of the lamp. , which eventually leads to the failure of the seal of the component, which seriously causes the casing to rupture. After cooling down again, the negative pressure will attract the moisture attached to the casing to cause leakage or short circuit.

Embodiment

[0022] Such as figure 2 , as shown in Fig. 4 and Fig. 5, several lamps 4 are communicated by ventilating electric wires 5, and the other end of lamps and lanterns 4 draws ventilating electric wires 5, and electric wires 5 pass through a profile on the bottom box 9 of ventilating junction box 8, which is sealed in the shape of "I". The ferrule 6 introduces gas and electricity into the box, and the common power line enters the box by the sealing ferrule 7 and is connected with the ventilation wire to supply electricity. There is a hole 11 on the box cover 10, and a microporous filter element 12 is installed outside the hole 11, which can filter Moisture in the air, the bottom box 9, the sealing ring 15, the box cover 10, and the filter element 12 form a breathable dry space. The enclosure 13 protects the filter element 12 from rainwater and splashing water. The blade 14 gap detours the junction space between the enclosure and the box cover 10 and enters the enclosure, and the r...

Abstract

The invention provides a dynamic waterproof method for a light fitting, comprising an aeration pipe with one end communicated with an inner cavity of a shell of the light fitting and the other end extended to dry place. Because the structure is adopted, when the temperature of the light fitting rises, and the pressure inside the shell of the light fitting increases, air in the shell of the light fitting is discharged through the aeration pipe for decompressing; when the temperature of the light fitting decreases, and the pressure in the shell of the light fitting reduces, air in the dry place enters the inside of the light fitting through the aeration pipe so as to dynamically balance the air pressure inside and outside the shell of the light fitting and eliminate the deformation of the shell of the light fitting suffered by air pressure, thereby preventing the decline of sealing property of the light fitting, and preventing damages of the light fitting caused by the decline of the sealing property of the light fitting, such as water seepage, creepage and short circuit.

Description

technical field [0001] The invention relates to a lamp, which is a waterproof method for the lamp. Background technique [0002] At present, in the existing technology, the outdoor lamps and lanterns are mainly sealed and waterproof for the components of the shell. However, outdoor lamps experience temperature changes and power-on heating in the use environment, and the internal air pressure of the lamps often changes, resulting in pressure that repeatedly squeezes the shell and damages the structure of the lamp. , which eventually leads to the failure of the seal of the component, which seriously causes the casing to rupture. After cooling down again, the negative pressure will attract the moisture attached to the casing to enter, causing leakage or short circuit. Contents of the invention [0003] The purpose of the present invention is to provide the lamp with a ventilating pipe connected to the dry atmosphere, release the gas pressure inside the lamp at any time, ensur...
