Description

A kind of great power LED explosion-proof lamp of high cooling efficiency

Technical field

The present invention relates to a kind of lighting, relate to the great power LED explosion-proof lamp of the high cooling efficiency of explosion-proof environments such as a kind of tunnel that is applied to the colliery, gas station, oil field specifically.

Background technology

Explosion-proof lamp is meant the light fixture for the various certain measures that prevent to light explosive mixture on every side such as explosive gas atmosphere, explosive dust atmosphere, methane gas etc. and take.Very important explosion-proof principle is exactly the temperature on the restriction case surface, component surface or the electronic devices and components surface that contact with damp, explosive dust in the explosion-proof lamp, and limits electric contact surface temperature and be lower than its minimum ignition temperature or ignition temperature.

Along with the raising of semi-conducting material and packaging technology, good technical background is provided for the development that high-brightness LED especially throws light on W level white light.Luminous flux and the light extraction efficiency of LED improve gradually, and cost of manufacture reduces gradually, add the advantage of energy-conserving and environment-protective, make its favor that more and more receives society, particularly in recent years, undergo an unusual development rapidly.The structure of LED lamp generally is made up of lamp housing, light source, lens, driving power etc.; The node temperature of led chip is one of main factor that influences light fixture service life; Therefore, the LED lamp generally can be designed with thermal component the temperature of chip is derived and distributes, for high-powered LED lamp; Particularly those need the high-powered LED lamp of long-time illumination continuously, and thermal component is even more important.Therefore, how improving radiating effect, reduce the chip node temperature, improve light fixture service life, is the key technology that present high-powered LED lamp needs most breakthrough.The method to set up and the structure thereof of existing thermal component generally are in the bulb periphery fin to be set, on housing wall, to offer louvre or to set up the device that is specifically designed to heat radiation, so that the heat that in time node is produced leaves, guarantee the operate as normal of lamp.

" the great power LED explosion-proof lamp of high cooling efficiency " of Chinese patent numbers 2007201826014 done good design on radiator structure.Its structure comprises shell, luminescence component, fin, and luminescence component comprises reflector, led light source and lens.Its technical characterictic is that fin is arranged in the outer shell passage radially; Dock with the inwall of shell the outer end of every fin; Inner and the external wall of a ring-type copper links, and the front end face of all fin forms the anchor ring of a taper indent, and reflector is arranged on this anchor ring; The front end face of annular barrel is plane, and led light source and lens are installed on this plane.Compared with prior art, communicate before and after in shell, being provided with, the fin of radiation barrier shape, more help air and do all around to flow and the transmission of heat and distributing around fin.

But this radiator structure still has deficiency in practical application; Because the odjective cause of contact-making surface is arranged between led chip and the fin; Make this contact-making surface become the bottleneck that transmits heat; The heat of led chip can not in time be transmitted on the fin fast, and the package dimension of led chip own is limited, and thermal capacitance is just limited; Working long hours to cause chip temperature slowly to rise, and makes lamp casing structurally have all over the body good heat radiation ability in vain and can not obtain chip heat fast timely and distribute.

Summary of the invention

The technical problem that the present invention solves provides a kind of great power LED explosion-proof lamp of high cooling efficiency, and this structure has radiating efficiency height, long service life, energy-conservation, antidetonation, explosion-proof characteristics.

In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of great power LED explosion-proof lamp of high cooling efficiency; Comprise lamp body, be fixed on the positive high-power LED bulb of lamp body, be installed in the light-passing board that the lamp body front is used to protect high-power LED bulb, it is characterized in that said light-passing board is an armorplate glass; Said light-passing board is embedded on the said lamp body through heat-conducting block; Said lamp body one end is provided with the cavity of opening, and binding post, power supply, lead sealing ring and lead compressing member are installed in the said cavity, and said binding post and power supply are fixed in the said cavity through the lead sealing ring; Said lead compressing member is fixed on the outside of said lead sealing ring, and said lead passes the lead compressing member successively and the lead sealing ring is electrically connected with said binding post, power supply and high-power LED bulb.

Preferably, the positive bottom of said lamp body is provided with reflector, and said high-power LED bulb is fixed on said reflector surface.

Preferably, on the said high-power LED bulb optical lens is installed also.

Preferably, be arranged at intervals with the radiating fin that increases area of dissipation at the back side of said lamp body.

The present invention's beneficial effect compared with prior art is: because light-passing board is embedded on the said lamp body through heat-conducting block, can improve the radiating efficiency of explosion-proof lamp like this.Non-maintaining, solve the problem of the original perishable frequent change of light source, reduced the maintenance cost of manual work and material.Long service life, have energy-conserving and environment-protective, antidetonation explosion-proof characteristics more than 50,000 hours theoretical service life.Brightness constancy adopts the constant pressure and flow drives, and light-source brightness is constant, has reduced kopiopia, improves the security of producing.The light source works temperature is low, and operating temperature has only about 50 degree, has stopped minute surface fouling and the fragmentation of chance water that high temperature causes.Be suitable under the severe environmental conditions and work, have the illumination of damp flame proof environment like the tunnel in colliery, gas station, oil field etc.Environment temperature subzero 20 is to 40 degrees centigrade above freezing, and degree of protection is more than or equal to IP65.
