Abstract
The utility model discloses a waterproof LED lamp housing. The waterproof LED lamp housing comprises a housing body and pressure balancing device. The housing body is composed of a light transmitting cover and a bottom cover, the light transmitting cover is clapped on the bottom cover to form a closed space with the bottom cover, and the bottom cover is provided with a balancing hole. The pressure balancing device is provided with an air duct and fixed onto the bottom cover, the air duct is inserted into the balancing hole to enter the inside of the lamp housing, and the joint portion of the air duct and the balancing hole is sealed. According to the waterproof LED lamp housing, the pressure balancing device can maintain the constant pressure of the closed space inside a lamp all the time to guarantee the tightness of the lamp and avoid water inflow.
Description
Technical field
The utility model relates to field of illumination lamp technology, especially relates to a kind of Waterproof LED lamp housing.
Background technology
To bulb, lamp housing being set is a kind of common safeguard measure; lamp housing is Packed; also blow-by has been arranged; generally all adopt airtight lamp housing in order to reach good waterproof effect now; yet can generate heat in the process that light fixture uses, air also can expand thereupon, and closing rear light fixture can be cooling; if things go on like this gummed place of light fixture is squeezed and can produces crack, water can be sucked in lamp after the cooling contraction of light fixture.
The utility model content
The utility model provides a kind of Waterproof LED lamp housing, can remain the constant voltage of confined space in light fixture by pressure equaliser, guarantees the sealing of light fixture, prevents into water.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
The Waterproof LED lamp housing, it is characterized in that: comprise housing, pressure equaliser, described housing is comprised of diffuser and end cover, diffuser is stuck in that end cover is upper hood-shapedly becomes an airtight space end of with, have balance pipe on end cover, described pressure equaliser is provided with wireway, and pressure equaliser is fixed on end cover, wireway inserts balance pipe and enters lamp housing inside, the junction sealing of wireway and balance pipe.
Preferably, cover with the junction of described diffuser and be provided with one deck fluid sealant at the described end.
Preferably, described diffuser is lucite, and cover of the described end is engineering plastics.
Preferably, described balance pipe is circular, and diameter is 8mm.
Preferably, described wireway adopts rubber tube.
Preferably, cover top outer rim of the described end is provided with external screw thread, and the lower internal edge of described printing opacity photograph is provided with internal thread.
The beneficial effect that the utility model reaches is: can guarantee constant pressure in lamp housing to guarantee reliable sealing by pressure equaliser, prevent that lamp housing from leaking.
Description of drawings
Fig. 1 is the structural representation of the utility model Waterproof LED lamp housing;
Fig. 2 is the structural representation of the utility model diffuser and end cover.
The specific embodiment
, in order to further describe technical characterstic of the present utility model and effect, below in conjunction with the drawings and specific embodiments, the utility model is described further.
﹠lt, b TranNum="73" ﹠gt, ﹠lt, / b ﹠gt, see figures.1.and.2, the utility model Waterproof LED lamp housing, comprise housing 1, pressure equaliser 4, housing 1 is comprised of diffuser 2 and end cover 3, described diffuser 2 materials are lucite, lower internal edge is provided with internal thread, end cover 3 materials are engineering plastics, the top outer rim is provided with external screw thread, diffuser 2 is connected together by internal thread and external screw thread with end cover 3, the inner confined space that forms, bulb is arranged in confined space, in order to reach better sealing effectiveness, in diffuser 2 and the junction 8 of end cover 3, one deck fluid sealant is set, have the circular balance pipe 5 of diameter 8mm on end cover, described pressure equaliser 4 is provided with rubber wireway 5, pressure equaliser 4 is fixed on end cover 3, wireway 5 inserts balance pipe and enters lamp housing inside, wireway 5 seals with the junction of balance pipe, in lamp housing, temperature rising volume of air expands when light fixture is worked, this moment, pressure equaliser 4 meetings kept the shell internal pressure constant air intake in shell by wireway 5, pressure equaliser 4 can enter air to keep constant pressure by wireway 5 in lamp housing 1 when light fixture cooling-air volume contraction.
Adopt the Waterproof LED lamp housing of above technical scheme to guarantee constant pressure in lamp housing by pressure equaliser, guarantee the sealing of light fixture, prevent that lamp housing from leaking.
Above-described embodiment does not limit the utility model in any form, all take to be equal to replace or technical scheme that the form of equivalent transformation obtains, within all dropping on protection domain of the present utility model.
