Description

The LED explosion-proof lamp of good heat dissipation effect

Technical field

The utility model relates to a kind of explosion-proof light device, the LED explosion-proof lamp of especially a kind of simple in structure, high-power, high brightness, good heat dissipation effect.

Background technology

At present, most of explosion-proof lamp still adopts conventional bulb to make, and its efficient is low, caloric value is big, the life-span is short, driving voltage is high, be prone to produce spark and electric arc; During like improper use or voltage instability, even can blast, therefore need be at the outside explosive-proof protector of making of bulb; Promptly adopt implosion guard and metal jube lamp device; Has complex structure, troublesome maintenance, shortcomings such as use cost height.Because LED is the solid cold light source, have electric light conversion ratio height, advantages such as caloric value is little, operating voltage is low, long service life, therefore, existing at present part explosion-proof lamp uses LED as lighting source.But; The light source of existing LED explosion-proof lamp and the heat conduction bad connection of power supply and shell; The heat that internal light source and power supply are produced can't be derived by housing immediately; Not only can make the too high and decay of led light source temperature or lost efficacy, but also possibly blast because of the ignition temperature that reaches extraneous damp.When particularly being lighting source with LED high-power, high brightness, above-mentioned phenomenon is even more serious.

Summary of the invention

The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, and the LED explosion-proof lamp of a kind of simple in structure, high-power, high brightness, good heat dissipation effect is provided.

The technical solution of the utility model is: a kind of LED explosion-proof lamp of good heat dissipation effect; Metab is arranged, on metab, be connected to metal shell, be connected to lampshade with metal shell; The heat sink that places on the metab is arranged in the metal shell; On heat sink, be provided with vertical cylindricality radiator, be equipped with the LED illuminating module in the front end face and the side of cylindricality radiator, the driving power that joins with the LED illuminating module places on the heat sink; On metab, be embedded with the sealed insulation body, binding post passes the sealed insulation body.

The utility model is simple in structure; The heat that the LED illuminating module is produced conducts on the heat sink through the cylindricality radiator, and the heat that driving power produced simultaneously also reaches on the heat sink, and the heat on the heat sink then sheds through metab and metal shell; Good heat dissipation effect; Can reduce the enclosure interior temperature, guarantee each electronic devices and components steady operation, prolong the service life of LED illumination light-emitting module; Even adopting LED high-power, high brightness is lighting source, can not produce various bad phenomenon because of temperature in the housing is too high yet.The all-sealed structure of the utility model can further improve the security reliability of light fixture.

The specific embodiment

Below with the specific embodiment of accompanying drawings the utility model.As shown in Figure 1: the metab 1 that metals such as useful aluminium alloy are made; On metab 1 through the sealing ring and the metal shell 2 that has been threaded; Be bonded with the lampshade 3 that clear glass is processed with metal shell 2, lampshade 3 compares at least greater than 1/2 with the length of cylindricality radiator 4.The heat sink 4 that places on the metab 1 is arranged in metal shell 2, between metab 1 and heat sink 4, heat conductive silica gel is arranged.On heat sink 4, be fixed with vertical cylindricality radiator 5 through screw, cylindricality radiator 5 is the external fin structure of hollow cylinder.Front end face and side at cylindricality radiator 4 all are connected to LED illuminating module 6, and promptly the Lights section exceeds metal shell 2, avoids its shading, and the illumination energy that is produced all radiates through transparent lampshade 3.The driving power 7 that joins with LED illuminating module 6 also is fixed on the heat sink 4, is embedded with sealed insulation body 8 in the centre of metab 1, and binding post 9 passes sealed insulation body 8, and power supply wiring can join through binding post 9 and driving power 7.
