Abstract
The utility model relates to lamp fittings, in particular to a lamp respirator capable of enabling air pressure inside the inner chamber of a sealed lamp to be balanced with the atmosphere. The lamp respirator comprises an air chamber, a breathing film and a connecting pipeline, wherein the breathing film is arranged inside the air chamber, and the connecting pipeline is connected between the air chamber and the inner chamber of the lamp. The lamp respirator is provided with a filtering chamber, and a cavernous body is arranged inside the filtering chamber; and an air gap is arranged at the connecting part of the filtering chamber and the connecting pipeline. According to the lamp respirator provided by the utility model, while harmful gas inside the chamber of the lamp is discharged through breathing, the waterproof and dust-proof effects of the lamp can be achieved, the purposes of lowering the temperature inside the chamber of the lamp or refraining the concentration of mixed gas inside the chamber of the battery can be achieved, the lamp is enabled to achieve an IP 65 seal rating effect, and an excellent lamp protecting effect can be achieved.
Description
Technical field
The utility model relates to a kind of lamp fittings, particularly a kind of light fixture respirator that is used for making sealed lamps inner chamber air pressure and atmospheric equilibrium.
Background technology
At present in the design of light fixture is used; The sealing property design is very high; So light fixture is in the use of lighting field; The inside cavity gas temperature of light fixture is normally very high, and the parts of lamp interior produce harmful effect to the performance and the safety of light fixture easily under the condition of high temperature, even causes light fixture Yin Gaowen actual effect or because of air pressure is high explosion takes place damaging.Light fixture is along with the increase of power can produce more heat in work.Because the cavity sealing property is high, the pressure of internal gas can increase because of the rising of temperature, produces draught head with extraneous gas, makes the air pressure disequilibrium of lamp chamber inside and outside portion.Especially the mist in the lead-acid battery chamber of light fixture (hydrogen that separates out when promptly charging and airborne mist) excessive concentration then can be blasted, and therefore makes light fixture in the process of using, have very big potential hazard.
Existing application number/patent No. is 2,009,203,065 13 the closed respirator that has membrane structure, has provided a kind of closed type lamp respirator that has membrane structure, makes that gas in the light fixture cavity cushions in the cavity of closed respirator, balance.This light fixture respirator volume is big, can not guarantee light fixture inner chamber inside and outside air pressure balance; The pernicious gas that the light fixture inner chamber produces can not be discharged; Break down to be difficult for discovering and change, lost the effect of light fixture respirator with in time repairing.
Summary of the invention
The main purpose of the utility model is to overcome the design defect of prior art, and a kind of light fixture respirator that is used to make sealed lamps inner chamber air pressure and atmospheric equilibrium that provides.
The purpose of the utility model can realize through following measure:
A kind of light fixture respirator of the utility model comprises air cavity, respiratory membrane, connecting line, and respiratory membrane is located in the air cavity, and connecting line is connected between air cavity and the light fixture inner chamber.Described light fixture respirator is provided with filter chamber, is provided with cavernous body in the filter chamber; Filter chamber and connecting line junction are provided with air gap.
The air gap of described filter chamber is communicated with the light fixture inner chamber through connecting line, and the air gap other end is through cavernous body and atmosphere.
Described air gap is crosswise, also can be lattice-shaped, is arranged in the internal diameter of connecting line.
Described connecting line is provided with external screw thread, is being provided with flexible seal ring with the filter chamber junction.
A kind of light fixture respirator of the utility model; Realizing the water proof and dust proof effect of light fixture simultaneously through breathing the pernicious gas of getting rid of the light fixture inside cavity; Reach and reduce lamp chamber internal temperature or suppress mixed gas concentration in the battery cavities; Make light fixture can reach the effect of IP65 sealing grade, have good light fixture protective effect.
Description of drawings
Fig. 1 is the explosive view of the utility model.
Fig. 2 is the respiratory organ structure profile.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
According to accompanying drawing, the light fixture respirator of the utility model comprises air cavity, respiratory membrane, connecting line 3, and respiratory membrane is located in the air cavity, and connecting line 3 is connected between air cavity and the light fixture inner chamber.The light fixture respirator is provided with filter chamber 2, is provided with cavernous body 1 in the filter chamber 2; Filter chamber 2 is provided with air gap 4 with connecting line 3 junctions.The air gap 4 of filter chamber 2 is communicated with the light fixture inner chamber through connecting line 3, and air gap 4 other ends are through cavernous body 1 and atmosphere; Air gap 4 is crosswise, also can be lattice-shaped, is arranged in the internal diameter of connecting line 3.
Connecting line 3 is provided with external screw thread, is being provided with flexible seal ring 6 with filter chamber 2 junctions.
In the practical implementation, filter chamber 2 is fixedly connected on the light fixture cavity 5 through nut 7, and sealing ring 6 prevents that under the thrust effect of nut 7 rainwater from passing through installing hole and flowing into light fixture cavity 5 inside.After light fixture cavity 5 temperature inside raise; Light fixture cavity 5 internal gas pressure are higher than light fixture cavity 5 atmosphere outside pressure; Then light fixture cavity 5 gas inside are discharged in the outside atmosphere after passing air gap 4, cavernous body 1 through respirator; Make light fixture cavity 5 inner with outside gas pressure intensities reach consistent, reach stability (like Fig. 2).The pore of air gap 4 designs is cross or lattice-shaped, can well prevent cavernous body 1 because gas pressure causes bad phenomenon such as distortion.
The light fixture respirator of the utility model, sealing ring 6 can prevent fully that outside water spray from waiting liquid to get into light fixture cavity 5 inside through respirator connecting line 3.The use of sealing ring 6 can effectively improve waterproof ability, reaches higher waterproofing protection grade.Cavernous body 1 is set in filter chamber 2 can reaches well dustproof grade.
The beneficial effect of the light fixture respirator of the utility model is; Realize the water proof and dust proof effect of light fixture simultaneously at the pernicious gas of getting rid of the light fixture inside cavity through respirator; Reach and reduce lamp chamber internal temperature or suppress mixed gas concentration in the battery cavities; Make light fixture can reach the effect of IP65 sealing grade, light fixture is had good protective action.
Carried out detailed description although it is pointed out that the light fixture respirator to the utility model here, with regard to this area staff, the similar modification of making on this basis of class Sihe all should belong to protection domain of the present invention.
