Abstract
The invention discloses a flameproof lamp which comprises a lamp body, a luminous source mounted in the lamp body, and a seal cover arranged on a flameproof casing outside the luminous source. Air pressure in the flameproof casing is higher or lower than atmospheric pressure outside the flame-proof casing, an air pressure sensor for sensing an air pressure difference between inside and outside of the flameproof casing in real time is mounted on the lamp body, and the air pressure sensor is connected with an alarm. The flameproof lamp is capable of monitoring whether the lamp is damaged or not in real time and is high in safety.
Description
Technical field
The present invention relates to a kind of light fixture, particularly a kind of explosion-proof lamp.
Background technology
Explosion-proof lamp refers to the hazardous area for imflammable gas and dust existence, can prevent imflammable gas and dust that the inner issuable electric arc of lamp, spark and high temperature ignite in surrounding environment, thereby reach the light fixture of requirement of explosion proof, as: the explosion-proof flashlight being used under the explosion-proof illuminating lamp that chemical plant is used and ore deposit.
Explosion-proof lamp generally consists of parts such as lamp body, light emitting source and flameproof enclosures, and wherein flameproof enclosure and lamp body are sealedly and fixedly connected and seal closure is located at light emitting source outside.Under normal condition, the gas in flameproof enclosure and the imflammable gas outside flameproof enclosure or dust are mutually isolated, thereby extraneous imflammable gas or dust can not enter the inner generation of avoiding blast of flameproof enclosure.Yet, sometimes can be because all unexpected factors cause the sealed environment in flameproof enclosure destroyed, as: flameproof enclosure breaks, gap etc. appears in flameproof enclosure and lamp body junction, and staff can not find this problem very timely, so, extraneous imflammable gas or dust will enter flameproof enclosure inside, are easy to produce blast after bright light.
Summary of the invention
The present invention seeks to: for the problems referred to above, provide a kind of explosion-proof lamp that can Real-Time Monitoring light fixture damages situation.
Technical scheme of the present invention is: a kind of explosion-proof lamp, the light emitting source and the seal closure that comprise lamp body, be contained in this lamp body are located at the flameproof enclosure outside described light emitting source, gas pressure in described flameproof enclosure is higher or lower than the atmospheric pressure outside described flameproof enclosure, the poor gas pressure sensor of the described flameproof enclosure inner and outer air pressure of real-time induction is installed on described lamp body, and this gas pressure sensor is connected with an alarm.
As preferably, the gas pressure in described flameproof enclosure is than the high 2～50kpa of the atmospheric pressure outside flameproof enclosure.
As preferably, the gas pressure in described flameproof enclosure is than the low 2～50kpa of the atmospheric pressure outside flameproof enclosure.
As preferably, described alarm is audible-visual annunciator.
Described light emitting source, for being LED light source, can be also the various light sources such as golden halogen light source.
Advantage of the present invention is: this explosion-proof lamp of the present invention, if the sealed environment of its flameproof enclosure inside is destroyed, the inside and outside gas of flameproof enclosure no longer mutually completely cuts off and can mutually flow so, finally making the inside and outside gas pressure difference of flameproof enclosure is zero, the gas pressure sensor being arranged on lamp body senses that the inside and outside gas pressure difference of flameproof enclosure has occurred after variation, by this communication to alarm, there is again sound and light signal and remind corresponding personnel that this explosion-proof lamp damages in alarm, need repairing or change, thering is very high security.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of the embodiment of the present invention;
Wherein: 1-lamp body, 2-light emitting source, 3-flameproof enclosure, 4-gas pressure sensor.
The specific embodiment
Embodiment: as shown in Figure 1, this explosion-proof lamp that the present embodiment provides, the light emitting source 2 and the seal closure that comprise lamp body 1, be contained in this lamp body are located at the flameproof enclosure 3 outside described light emitting source, and wherein light emitting source 2 can adopt the various forms such as LED light source, golden halogen light emitting source.
The key improvements of the present embodiment is: the gas pressure in described flameproof enclosure 3 is higher than the atmospheric pressure outside (or lower than) described flameproof enclosure 3, the poor gas pressure sensor 4 of described flameproof enclosure 3 inner and outer air pressures of real-time induction is installed on described lamp body 1, and this gas pressure sensor 4 is connected with an alarm (not shown in FIG.).Described alarm can adopt multiple alarm form, and in this example, this alarm is the audible-visual annunciator that can send acoustic alarm signal, visual alarm can occur again.Certainly, described alarm also can adopt other versions, such as: the computer being connected with described gas pressure sensor 4.
If flameproof enclosure 3 self breaks, or there is gap with lamp body 1 junction in flameproof enclosure 3, and cause the sealed environment of flameproof enclosure 3 inside destroyed, the inside and outside gas of flameproof enclosure 3 no longer mutually completely cuts off and can mutually flow so, finally making flameproof enclosure 3 inside and outside gas pressure difference is zero, the gas pressure sensor 4 being arranged on lamp body 1 senses that flameproof enclosure 3 inside and outside gas pressure difference have occurred after variation, by this communication to alarm, there is again sound and light signal and remind corresponding personnel that this explosion-proof lamp damages in alarm, need repairing or change.
Generally, the gas pressure in flameproof enclosure 3 is more best than the atmospheric pressure outside flameproof enclosure 3 high (or low) 2～50kpa.
Certainly, above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow people can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformation or modification that according to the present invention, the Spirit Essence of main technical schemes is done, within all should being encompassed in protection scope of the present invention.
