Abstract
A pressure balancing breather for a light-emitting diode (LED) lamp comprises a connector connected with a lamp body, and is characterized in that the connector is a 'cross'-shaped hollow connector; a ceramic filter is sleeved at a longitudinal end of the hollow connector; a compressing cover is arranged at the periphery of the ceramic filter, and is connected with a transverse end of the hollow connector by covering a part from the ceramic filter to the middle of the hollow connector; the other end of the hollow connector in the longitudinal direction is connected with the lamp body; through holes are respectively formed in the top and the bottom of the longitudinal connecting end of the hollow connector; and the through hole in the bottom of the longitudinal connecting end is communicated with the inside of the lamp body. By the structure, the pressures on the inner side and the outer side of a shell are balanced when the temperature and the pressure of a lamp housing are changed. As long as air is in contact with the filter, the air inside the lamp body and the air outside the lamp body can be freely exchanged. The ceramic filter can effectively filter water and dust, and the corrosion resistance and the weather resistance of the ceramic filter are higher than those of a breathable film, so that the lamp can stably run for a long time.
Description
Technical field
The present invention relates to LED lamp applications field, particularly a kind of LED light fixture pressure balance respirator.
Background technology
The housing of luminaire of outdoor layout is bearing extraneous temperature and pressure continually to be changed.Temperature, dust, dirt and the moisture that constantly changes affects stability and the life-span of outdoor lighting lamp widely.For example, the rainfall meeting causes housing of luminaire to produce rapid drop in temperature.The rapid reduction of temperature can cause the inner 150mbar of generation of case even larger vacuum.Like this, air and moisture just enter casing inside by seal clearance.Moisture is attached on the inwall of casing and condenses into the globule.This will have a strong impact on the performance of product.And the continuous variation of temperature makes sealing strip along with STRESS VARIATION, that sealing strip is produced is tired-this means to be not only moisture, comprise that water and various liquid finally can see through the slit and enter case inside, because present light fixture has electronic devices and components, be exactly liquid and electronic devices and components are afraid of most, liquid flow into behind the electric component directly that consequence is short circuit, finally causes light fixture to burn inefficacy.The existing solution in market is to adopt a kind of nano ventilated film to realize the purpose that water proof and dust proof is ventilative, this ventilated membrane extremely easily lost efficacy under rainwash in real world applications, mainly be that water droplet can be attached on the ventilated membrane easily, because ventilated membrane is surperficial smaller, under heavy rain washes away to adhere to water droplet too large, under normal circumstances under the effect of rainwater, light fixture self-temperature suppression ratio is very fast, therefore under the effect of temperature difference, be easy to suck moisture or directly stop up the air exchange mouth, thereby lost the effect that respirator should play.
Summary of the invention
In order to solve the above problems, the object of the present invention is to provide a kind of LED light fixture pressure balance respirator, the negative effect that the pressure reduction that it can protect housing of luminaire to avoid causing owing to variations in temperature effectively brings to light fixture.The present invention makes the pressure of housing of luminaire both sides, balance shell inside and outside when temperature and pressure changes under the effect of the ceramic filter that adopts ceramic post sintering to form.Reduce the stress that sealing strip bears, and dewfall is down to minimum.And under the washing away of heavy rain, because that the ceramic filter that ceramic post sintering forms has adopted is columnar structured, just can allow air free exchange inside and outside lamp body as long as realized that air contacts with filter.Ceramic filter is the invasion of filtered water, dust effectively, and its corrosion resistance, weatherability are more excellent than ventilated membrane, thereby realizes the purpose of light fixture operation steady in a long-term.
The present invention solves the technical scheme that its problem adopts:
A kind of LED light fixture pressure balance respirator, comprise the connector that is connected with lamp body, it is characterized in that: described connector is the hollow connector that is " ten " font, the vertical end of described hollow connector is socketed with a ceramic filter, ceramic filter is arranged with a gland outward, and described gland is connected with hollow connector transverse end by covering ceramic filter to hollow connector middle part; The vertical other end of described hollow connector is connected with lamp body, vertically all is provided with through hole on the link top and bottom, and described bottom through-hole communicates with lamp body inside.
As improvement of the technical scheme, described hollow connector is provided with external screw thread with the lamp body link and is connected with lamp body.
As improvement of the technical scheme, described hollow connector transverse end is connected by the fastened by screw mode with gland.
As improvement of the technical scheme, described ceramic filter is dome-shaped or polygonized structure.
As improvement of the technical scheme, the corresponding ceramic filter of described gland is dome-shaped or polygonized structure.
As improvement of the technical scheme, described gland transversely have a through hole, described number of openings is minimum to be 1.
As improvement of the technical scheme, the junction of described hollow connector and gland, lamp body is provided with silica gel and encloses the cushion seal effect.
As improvement of the technical scheme, described hollow connector top through hole is lower than more than the degree of depth 3mm of ceramic filter.
The invention has the beneficial effects as follows: the invention provides a kind of LED light fixture pressure balance respirator, the negative effect that the pressure reduction that it can protect housing of luminaire to avoid causing owing to variations in temperature effectively brings to light fixture.The present invention makes the pressure of housing of luminaire both sides, balance shell inside and outside when temperature and pressure changes under the effect of the ceramic filter that adopts ceramic post sintering to form.Reduce the stress that sealing strip bears, and dewfall is down to minimum.And under the washing away of heavy rain, because the filter that ceramic post sintering forms has adopted cylinder or polygon barrel structure, just can allow air free exchange inside and outside lamp body as long as realized that air contacts with ceramic filter.Ceramic filter is the invasion of filtered water, dust effectively, and its corrosion resistance, weatherability are more excellent than ventilated membrane, thereby realizes light fixture operation steady in a long-term.
