Abstract
The present invention provides a dynamic waterproof method for a light fitting, comprising a shell of the light fitting and an aeration pipe with one end communicated with an inner cavity of the 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 low pressure water sucking inside the light fitting and damages caused by the low pressure water sucking, such as creepage and short circuit, and prolonging the service life of the light fitting.
Description
Technical field
The present invention relates to light fixture, particularly is a kind of light fixture venting and waterproof device and method.
Background technology
Present prior art, the light fixture of outdoor use mainly is the assembly airtight waterproof of shell, but outdoor lamp is in environment for use, experience temperature Change and heating power influence, lamp interior air pressure often changes, and produces pressure and pushes shell repeatedly, destroy the structure of light fixture, finally cause the assembly seal failure, the serious outer casing rupture that causes, the cooling back produces moisture that negative pressure will attract to adhere on the shell and causes electric leakage or short circuit in going into once more.
Summary of the invention
The present invention seeks to: provide breather pipe to be communicated with dry atmosphere to light fixture; at any time discharge the gas pressure intensity of lamp interior; guarantee the light fixture internal and external pressure balance; dynamically eliminate the suffered gas pressure of lamp outer casing; the sealing property that prevents lamp outer casing descends; prevent negative pressure suction, the damage of can not leaking of protection light fixture.
The present invention is achieved in that a kind of light fixture venting and waterproof device, comprises lamp outer casing, and breather pipe is arranged on lamp outer casing, and breather pipe is communicated with light fixture inner chamber to a dry place.
The present invention is characterised in that: also have an installing hole on the lamp outer casing, one end of ventilation mouth is installed on the installing hole, the other end extends to dry place, and dry place can be the building interior space of no rainwater, also can be the artificial no rainwater guard space of all kinds of dryings that is provided with;
The present invention is characterised in that: breather pipe and lamp outer casing are integrated into;
The present invention is characterised in that: some light fixtures are connected by breather pipe, communicate with dry place by breather pipe again;
The present invention is characterised in that: breather pipe and electric wire are integrated into the ventilation power line;
The present invention is characterised in that: the ventilation electric wire enters lamp interior by installing hole, and the other end extends in the wire junction box of ventilation;
The present invention is characterised in that: passage is arranged on the wire junction box, and passage covers the gas-liquid separation material with microcellular structure, and the ventilative casing of dash, forms a ventilative dry place in the middle of the box, and the ventilation electric wire is communicated with box and light fixture;
The present invention is characterised in that: some light fixtures are communicated with by the ventilation electric wire, and are communicated with one or several above-mentioned ventilation terminal box;
The present invention is characterised in that: some light fixtures pass through waterproof butt joint energising air guide by the ventilation electric wire, and are communicated with one or several above-mentioned ventilation terminal box;
A kind of ventilation waterproof method of light fixture venting and waterproof device, when lamp temperatures raises, the lamp outer casing internal pressure increases, gas in the lamp outer casing is discharged pressure release by breather pipe, when lamp temperatures reduces, pressure in the lamp outer casing reduces, and the air of dry place enters lamp interior by breather pipe, dynamically balance lamp outer casing inner and outer air pressure.
Lamp dynamic water-proof device method of the present invention comprises a breather pipe, and breather pipe one end communicates with the lamp outer casing inner chamber, and the other end extends to dry place.Owing to adopt such structure, when lamp temperatures raises, the lamp outer casing internal pressure increases, and the gas in the lamp outer casing is discharged pressure release by breather pipe, when lamp temperatures reduces, pressure in the lamp outer casing reduces, the air of dry place enters lamp interior by breather pipe, and dynamically balance lamp outer casing inner and outer air pressure is eliminated the gas pressure distortion that lamp outer casing is subjected to, prevented sealing performance of lamp decline, and prevented that the light fixture water inlet electric leakage, the short circuit that therefore cause from damaging.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, a kind of light fixture venting and waterproof device comprises lamp outer casing 1, and a breather pipe 2 is arranged on lamp outer casing 1, and the other end of ventilation mouth 2 extends to dry place 3, has ventilative function, eliminates lamp interior air pressure at any time, prevents the negative pressure suction.
Embodiment
As Fig. 2; Fig. 4; shown in Figure 5; some light fixtures 4 are communicated with by ventilation electric wire 5; the other end of light fixture 4 is drawn ventilation electric wire 5; electric wire 5 pass the ventilation terminal box 8 end box 9 on a profile be " worker " font sealing ring 6; gas; electricity is introduced in the box; normal power cord by sealing ring 7 enter in the box be connected with the ventilation electric wire to; on the lid 10 porose 11; the hole 11 outer micropore filter elements 12 that are equipped with; vaporific moisture in can filtered air; end box 9 and sealing ring 15; lid 10; filter core 12 is formed a ventilative dry place; casing 13 protection filter cores 12 are not subjected to rainwater and the water that splashes drenches saturated actual effect; air enters in the casing by the detour space, joint portion of casing and lid 10, blade 14 gaps of blind shaped, and the rainwater that drenches on the box 8 is drained along constant slope blade 14.
Fig. 3 is respectively two cores, three cores, the four-core sectional view of ventilation electric wire; the dry place of passage 16 conducting light fixtures and terminal box wherein; its profiled-cross-section prevents that in addition the electric wire bending from blocking the effect of pore; metal-cored lead 17 is supplied to light fixture 4 with the power supply in the terminal box, and 19 of insulating barrier 18 and crusts support protective effect.
Said structure can dynamically be released lamp interior because the gas pressure that variations in temperature produces prevents the negative pressure suction, prevents that sealing performance of lamp is destroyed, prolong light fixture service life, and do not change production, the mounting process that has light fixture now, and not changing the outward appearance of light fixture, cost is low.
