Abstract
The utility model relates to a spark-less anti-explosion LED (Light Emitting Diode) lamp, which comprises a light-distributing lens, a lampshade, a driving power supply box, a mounting handle, a lens fixing plate, an LED light source module, a driving power supply and an anti-explosion cable entry, wherein the light-distributing lens is made of toughened glass; a through hole radiating lampshade is served as the lampshade; the LED light source module is directly fixed at the bottom at the center of the lampshade through a bolt; a driving power supply is poured with epoxy resin and is mounted in the driving power supply box; an anti-explosion cable inlet is formed at the top of the driving power supply box; and a threaded anti-explosion joint plane is at the joint of the anti-explosion cable inlet and the anti-explosion cable entry. Reliable anti-explosion measures are taken for all electric elements, so that the lamp can efficiently prevent sparks from generating and can avoid the illuminating fault at dangerous temperature, caused by the heating of the LED lamp, the range of application of the LED lamp is widened, and the lamp can be used in gas or dust explosion dangerous places and is safe and reliable.
Description
Technical field:
The utility model belongs to field of light fittings, is specifically related to a kind of no-spark anti-explosion LED lamps that can avoid producing spark.
Background technology:
In technique known; Normally used LED lamp, because of it has advantages such as energy-conserving and environment-protective, volume is little, the life-span is long, the application in production, storage, rescue, road, operating mode, tunnel, communication, automobile is more next extensively; But because the LED lamp can produce electric spark inevitably or form red-hot surface when work; In case meet with damp, will cause the generation of explosion accident, cause any property loss and life security; The 2nd, the brightness of LED lamp is big especially, is easy to make that luminous energy becomes heat energy, at this moment; If the LED lamp can not dispel the heat as early as possible; Its life-span will reduce greatly, and LED lamp of the prior art, because of its architectural characteristic is limit; Radiating effect is bad, causes the lamp interior junction temperature too high and explosion caused easily; The 3rd, the common LED lamp, because of to damp short of reliable explosion precaution, being in operation to produce electric spark or dangerous temperature, if damp is arranged, just has potential safety hazard on every side, and then causes outside danger easily.Therefore, the common LED light fixture is not because of possessing the hazardous area that explosion prevention function can not be used to exist damp.
The utility model content:
The purpose of the utility model is the deficiency that is to overcome above-mentioned prior art, provides a kind of rational in infrastructure, good heat dissipation effect, and can use at gas or dust explosion risk place, and safe and reliable no-spark anti-explosion LED lamps.
The technical scheme that the purpose of realization the utility model is taked is: this anti-explosion LED lamps is by light-distribution lens, lens holder plate, led light source, lampshade, driving power box; Driving power, mounting knob, anti-explosion cable introducing device are formed, and wherein, light-distribution lens adopts the safety glass goods; Lampshade adopts via hole heat radiation lampshade; Led light source adopts the Modular LED light source, and is fixed on the bottom in lampshade centre through screw, and driving power adopts epoxy resin to water envelope and handles and be installed in the driving power box; Be provided with anti-explosion cable at the top of driving power box and introduce the hole, threaded flameproof joint is adopted in the junction of this hole and anti-explosion cable introducing device.
Said via hole heat radiation lampshade adopts the three-dimensional through-hole structure of multiaspect of die cast.
Sealing ring is equipped with in said junction between light-distribution lens and lens holder plate.
The no-spark anti-explosion LED lamps of processing according to such scheme; Can quicken the natural air convection current through the lampshade of the three-dimensional through-hole structure of multiaspect on the one hand; Take away the heat that the LED lamp produces when illumination; Make the light source module of LED lamp when work, can reach desirable radiating effect, improved the practical function of LED lamp heat radiation greatly, prolonged the service life of LED lamp thus.On the other hand through each electrical equipment of this light fixture is increased reliable explosion precaution; Can prevent effectively that electric spark from producing; Avoid occurring the light failure of dangerous temperature because of the heating of LED lamp; Widened the scope of application of LED lamp thus, it can be used in the hazardous area that has damp, and security reliability has been high.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the cross-sectional view of Fig. 1.
The specific embodiment
Referring to Fig. 1,2; The no-spark anti-explosion LED lamps of the utility model; Form by light-distribution lens 1, lampshade 2, driving power box 3, mounting knob 4, lens holder plate 5, led light source 6, driving power 7, anti-explosion cable introducing device 8; Wherein, light-distribution lens 1 adopts the safety glass goods, in order to improve impact resistance; Sealing ring 9 is equipped with in junction between light-distribution lens 1 and the lens holder plate 5, can improve degree of protection and security reliability.Led light source 6 adopts the Modular LED light sources, and is fixed on the bottom in lampshade 2 centres through screw, and lampshade 2 adopts via holes heat radiation lampshades; Be to constitute by the three-dimensional through-hole structure of the multiaspect of die cast; Be beneficial to heat radiation, lampshade 2 adopts the three-dimensional through-hole structure of multiaspect, and is big with the air contact area on the one hand; Can quicken natural convection air, good heat dissipation effect; The heat that the LED lamp is produced directly distributes through via hole heat radiation lampshade, avoids the temperature of LED lamp too high.Driving power 7 adopts epoxy resin to water envelope and handles, and is installed in the driving power box 3, can limit effectively electric spark generation and with the contacting of extraneous damp, improved security.Be provided with anti-explosion cable at the top of driving power box 3 and introduce the hole, threaded flameproof joint is adopted in the junction of this hole and anti-explosion cable introducing device 8, guarantees safe and reliable.Anti-explosion cable introducing device 8 in this case adopts known INCREASEDSAFETY anti-explosion cable introducing device, and its structure repeats no more.This anti-explosion LED lamps is whole through the explosion-proof processing of no-spark; Can implement lighting at explosion hazard area; Widened the scope of application of LED light fixture thus; Can be widely used in the hazardous area that has damp, also can spread all among particular job occasions such as being applied to explosion-proof, field work, mine, military behave or the abominable working environment.
