Description
Technical field
The utility model relates to a kind of explosion-proof lamp, especially relates to flameproof LED anti-explosion lamp.It is applicable to the places such as underworkings, chamber, concentrator station, electric substation, pump house; Also be applicable to containing in the hazardous environment such as damp or steam, and illumination use is done in various indoor and outdoor operation (industry such as electric power, metallurgy, railway, mine, harbour, municipal administration) plant area, station, venue and the place such as railway tunnel, bridges and culverts.
Background technology
LED anti-explosion lamp kind of the prior art is more, and its top of explosion-proof lamp the most common is the shell of spherical cap shape, and housing exterior is designed with reinforcement, and the top of shell is the female tubulose mounting bracket of band; Be connected with Transparent Parts below shell, the vertical extension of Transparent Parts is longer, and therefore Transparent Parts outside is covered with protection network.Transparent Parts internal light source generally still adopts conventional light source, as fluorescent lamp, Metal halogen lamp etc.
Assembly structure and the prior art of Transparent Parts of the present utility model and shell are different.Prior art generally adopts the upper plane of Transparent Parts to do explosion suppresion surface or does hermetically-sealed construction by plane pressure seal ring in Transparent Parts.Transparent Parts is become concordant with shelling machine, and due to the characteristic of Transparent Parts processing technology, Transparent Parts flange face cannot be accomplished smooth, and deflection is within 2mm, though manual polishing do not accomplish yet with casing explosion-proof face gap 0.2mm within.So uniformity is just difficult to ensure.
Above-mentioned explosion-proof lamp of the prior art to design by the carrying out of GB GB3836.1-2000 and certification, do not meet the requirement of Kunming Market GB3836.1-2010, and field of employment limitation is large, if by I class Explosion-proof Design, can only be used for coal mine gas gas environment; By II class Explosion-proof Design, other explosive gas atmosphere except coal mine gas gas can only be used for, as ethene, hydrogen etc.There is following defect in this external technical elements:
1. adopt conventional light source, light fixture optical efficiency is low; Light fixture is work in 24 hours, not energy-conservation.
2. mounting means is single, can not meet the need of market.
3. be with protection network, the dust of Transparent Parts surface accumulation is not easy cleaning, affects whole light effect.
4. light fixture is in rated operation always, and the light source normal phase is in operating temperature ratings state, and the service life of whole lamp is lower.
Utility model content
It is good that the purpose of this utility model is to provide a kind of explosion-proof performance, the circular explosion-proof lamp of the one that use cost is lower.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of circular explosion-proof lamp, it comprises shell and Transparent Parts, and shell upper is fixedly connected with lifting bolt, airtightly with Transparent Parts under shell is connected, and it is characterized in that: shell is made up of the upper casing connected successively from top to bottom, mesochite and lower casing; Upper shell upper portion connects lifting bolt, and upper casing bottom is combined with mesochite by plane flame-proof faying face, and plane flame-proof faying face is provided with sealing ring; The left and right sides of mesochite is designed with cable interface respectively, and the cable interface of side is connected with introducing device, and lead-in cable penetrates on the binding post that is connected in mesochite inner chamber from introducing device, and binding post is connected with driving power; The cable interface of opposite side is closed by clamp nut and plug, and plug and cable penetrate the sealing gasket being provided with annular between mouthful sidewall; Mesochite bottom is connected with lower casing by cylindrical flameproof joint, and cylindrical flameproof joint is provided with " O " RunddichtringO; Lower casing inner chamber is provided with driving power; Lower casing inside middle portion is designed with the horizontal annular plate of one, and annular slab is downward-sloping extends into dish, and the dish wall of inclination is provided with optical system, and optical system comprises LED light source and reflector; Spherical crown shape Transparent Parts covers on the outside of optical system, the horizontal outer of Transparent Parts is fixed by pressing plate, the rubber cushion of annular is housed between the horizontal annular plate lower surface inside the horizontal outer upper surface of Transparent Parts and lower casing, and horizontal outer sidewall and the lower casing madial wall of Transparent Parts adopt adhesive joint face to be connected; Pressing plate is threaded with lower casing.
The circular explosion-proof lamp of above-mentioned one, it is characterized in that: introducing device is made up of clamp nut, packing ring and cable sealing ring, be threaded with cable interface at clamp nut, the packing ring of annular and cable sealing ring are pressed on cable interface madial wall by clamp nut, and cable sealing ring and lead-in cable are tightly connected; Be provided with intelligent dimming module in the bottom of lower casing, intelligent dimming module is made up of microwave induced module and control circuit, and be plate aerial in the middle part of microwave induced module, intelligent dimming module is connected with driving power by input-output line group; Intelligent dimming module installs rear plate antennas orthogonal downward.
The left and right sides of the utility model mesochite is designed with cable interface respectively, generally, only needs the cable interface of side to connect lead-in cable, is compressed by clamp nut.Opposite side blocks with plug at ordinary times, when light fixture needs in parallel, is taken down by plug, connects shunt cable.Greatly reduce cloth electricity workload.
Because Transparent Parts adopts spherical cap shape, can improve the effective rate of utilization of light on the one hand, make the light full illumination of light fixture in long and narrow tunnel, avoid waste irradiation, in the tunnel of same distance, the light fixture quantity of use is little, reaches energy-saving effect.Transparent Parts surface area reduces greatly on the other hand, and structural strength increases, and no longer needs protection network, then add whole lamp degree of protection and reach IP66, facilitate client to rinse the dust of Transparent Parts surface long time integration in use with giant, effectively can improve the lumen utilization rate of light fixture.
Owing to having installed intelligent dimming module additional, when light fixture works at ordinary times, can two states be in: 20% brightness time entirely bright, idle during work, idlely specifically need bright how much can carrying out to arrange (from 0-100%).When there being people to come into field of illumination, light fixture is entirely bright.And underworkings major part region and most of the time are all depopulated zones, as: gallery, inclined shaft lane, electric substation, pump house etc., these light fixtures are in idle condition at ordinary times, greatly can save electric energy, directly produce economic benefit.
