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 application, particularly a kind of LED lamp pressure balance respirator.
Background technology
The housing of luminaire of outdoor layout subjects extraneous temperature and pressure change continually.The temperature of continuous change, dust, dirt and moisture affect stability and the life-span of outdoor lighting lamp widely.Such as, the temperature that rainfall can cause housing of luminaire to produce sharply declines.The sharply reduction of temperature can cause casing interior to produce the even larger vacuum of 150mbar.Like this, air and moisture just enter casing internal by seal clearance.The inwall that moisture is attached to casing condenses into the globule.This will have a strong impact on the performance of product.And the continuous change of temperature makes sealing strip along with STRESS VARIATION, finally to make sealing strip produce tired-this means to be not only moisture, comprise water and various liquid finally can enter casing interior through gap, because present light fixture has electronic devices and components, and electronic devices and components are afraid of most is exactly liquid, after liquid flow into electric component, direct consequence is short circuit, finally causes light fixture to burn inefficacy.The existing solution in market adopts a kind of nano ventilated film to realize the ventilative object of water proof and dust proof, in real world applications, under rainwash, this ventilated membrane extremely easily lost efficacy, mainly water droplet can be attached on ventilated membrane easily, because the surface of ventilated membrane is smaller, attachment water droplet under heavy rain washes away is 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 direct blocking air exchange mouth, thus lose 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 lamp pressure balance respirator, the negative effect that it can protect housing of luminaire to bring to light fixture from the pressure reduction caused due to variations in temperature effectively.The present invention, under the effect of ceramic filter adopting ceramic post sintering, makes the pressure of housing of luminaire both sides, balance shell inside and outside when temperature and pressure changes.Reduce the stress that sealing strip bears, and condensation is down to minimum.And under the washing away of heavy rain, the ceramic filter due to ceramic post sintering have employed columnar structured, as long as achieve air and filter contacts just can allow air free exchange inside and outside lamp body.Ceramic filter can the invasion of effectively filtered water, dust, and its corrosion resistance, weatherability comparatively ventilated membrane are more excellent, thus realizes the object that light fixture long-term stability runs.
The present invention solves the technical scheme that its problem adopts:
A kind of LED lamp pressure balance respirator, comprise the connector be connected with lamp body, it is characterized in that: described connector is the hollow connectors in " ten " font, the longitudinal one end of described hollow connectors is socketed with a ceramic filter, be arranged with a gland outside ceramic filter, described gland is connected with hollow connectors transverse end by covering in the middle part of ceramic filter to hollow connectors; The longitudinal other end of described hollow connectors is connected with lamp body, and longitudinal link top and bottom is all provided with through hole, and described bottom through-hole communicates with lamp body inside.
As the improvement of technique scheme, described hollow connectors is provided with external screw thread with lamp body link and is connected with lamp body.
As the improvement of technique scheme, described hollow connectors transverse end is fixed by screw mode with gland and is connected.
As the improvement of technique scheme, described ceramic filter is dome-shaped or polygonized structure.
As the improvement of technique scheme, the corresponding ceramic filter of described gland is dome-shaped or polygonized structure.
As the improvement of technique scheme, described gland transversely have through hole, described number of openings is minimum is 1.
As the improvement of technique scheme, the junction of described hollow connectors and gland, lamp body is provided with silica gel and encloses cushion seal effect.
As the improvement of technique scheme, described hollow connectors 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 lamp pressure balance respirator, the negative effect that it can protect housing of luminaire to bring to light fixture from the pressure reduction caused due to variations in temperature effectively.The present invention, under the effect of ceramic filter adopting ceramic post sintering, makes the pressure of housing of luminaire both sides, balance shell inside and outside when temperature and pressure changes.Reduce the stress that sealing strip bears, and condensation is down to minimum.And under the washing away of heavy rain, the filter due to ceramic post sintering have employed cylinder or polygon barrel structure, contact with ceramic filter just can allow air free exchange inside and outside lamp body as long as achieve air.Ceramic filter can the invasion of effectively filtered water, dust, and its corrosion resistance, weatherability comparatively ventilated membrane are more excellent, thus realizes light fixture long-term stability and run.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
