Description
Technical field
The present invention relates to technical field of semiconductor illumination, specifically belong to a kind of integral LED bulkhead lamp capable of high efficiency and heat radiation.
Background technology
Traditional Mining lamps and lanterns; Its light source adopts high-pressure sodium lamp or the metal halide lamp and the 1000W iodine-tungsten lamp etc. of high-power (about 400W) mostly; The thick heaviness of processing of bulkhead lamp capable lamp, power consumption is big, maintenance cost is high, environmental pollution is serious, and illuminating effect is all unsatisfactory at aspect such as color transformed.
Nineteen sixty-five, global first item commercialization light emitting diode (LED) is born, and along with continuous advancement in technology, the development of LED is quite rapid, and in recent years, the luminous efficiency of the LED of some color substantially exceeds incandescent lamp, even reaches the luminous efficiency of fluorescent lamp.Compare with traditional bulkhead lamp capable electric light source, the basic nonhazardous of led light source, no electromagnetic pollution and have that volume is little, energy consumption is low, light efficiency is high, caloric value is relatively low and many-sided advantage such as long service life can substitute conventional light source fully and make bulkhead lamp capable.
Consider that the single chip LED luminosity is not enough; The LED light fixture generally adopts led array formula structure; Produced thus that LED light fixture heat is concentrated, local temperature is too high, thereby caused that circuit control system is unstable, energy consumption is excessive, problems such as lamp life reduction; Thus, how to solve heat radiation and then become the required difficult problem of facing of array-type LED light fixture.
In recent years, white light, glory LED use in the Projecting Lamp field to some extent, but relevant led light source heat radiation, and the led light source heating does not obtain more perfectly solving to the problems such as influence of electric component.
In one Chinese patent application publication number CN1594962A document; Related to a kind of bar-shaped LED light fixture, its light fixture does not have radiator structure, and electric component and led light source are integrated in a circuit board simultaneously; Led light source warming-up effect electric component causes very big unstability.
In one Chinese patent application publication number CN1734846A document, related to a kind of bar-shaped LED projecting light, electric components such as its power supply and drive circuit are not arranged at etc. in the body, but outside independent setting of light fixture.Though this kind split-type design method has reduced the influence of led light source heating to electric component, has brought inconvenience to cost control and lamp installation etc.
In one Chinese patent application publication number CN1767815Y and CN2886319Y document, each discloses a kind of linear LED Projecting Lamp, in these two kinds of schemes; Led light source and electrical part have partly been carried out spatial separation; But do not design radiator structure, therefore, waiting the alluvial of body internal heat; Led light source heating still exists the influence of electrical part, and the power consumption of light fixture, stability, service life, various aspects of performance still can be affected.
In one Chinese patent application publication number CN1760585A document; Disclose a kind of bar-shaped LED light fixture, it places the closed chamber of falling heat-transfer iknsulating liquid with electric component, separates with led light source to reach electric component; Though this method can effectively realize heat radiation and isolate; But production cost is too high, and extremely inconvenience of processing, maintenance is not too suitable in present stage popularity production.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art; Provide a kind of and have that high efficiency and heat radiation effect, energy consumption are low, long service life, optical energy attenuation be little, the integral LED bulkhead lamp capable of cheap relatively, the simple relatively powerful high efficiency and heat radiation of processing of production cost simultaneously.
The technical scheme that the present invention adopts is following:
A kind of integral LED bulkhead lamp capable of high efficiency and heat radiation; Comprise lamp body mounting disc, mounting bracket, power pack loam cake, power pack sealing ring, LED power supply and Drive and Control Circuit, power pack lower cover, lamp body shell, led light source, lamp body sealing ring, light management assembly, light penetrating panel; Said led light source is arranged on the lamp body outer casing inner wall along the sealing chamber array of lamp body enclosure; Be close to the lamp body outer casing inner wall and form thermo-contact; It is indoor that LED power supply and Drive and Control Circuit are positioned at another enclosed cavity; It is indoor that the cable-through hole that power line is reserved through mounting bracket is linked into another enclosed cavity that LED power supply and Drive and Control Circuit are set, and the power line other end is linked into electrical network and forms the lighting circuit connection.
The upper surface of described lamp body shell inner cavity is provided with the heat radiation rib, and radiating ribs is isolated the sealing chamber of settling led light source and another sealing chamber of settling LED power supply and Drive and Control Circuit.
Described LED power supply and Drive and Control Circuit directly are arranged on the lamp body outer casing inner wall, are integrally formed the formula structure.
Described led light source can be single led light source and arranges, and also can be a plurality of modularity led light sources and arranges, and can also arrange with the integrated LED light source.
Said lamp body shell is that rigid, heat-conductive material is processed.
The material of said light penetrating panel is safety glass or acryl.
Said light management assembly is lens, reflector or grid.
Compared with present technology, beneficial effect of the present invention is following:
Led light source of the present invention and lamp body shell directly carry out thermo-contact; The aluminium base of filling in the LED light fixture as none; Wherein directly contact wall outside heat radiation rib in traditional LED Mining lamps and lanterns difference in its led light source and lamp body shell; Cancel the aluminium base of traditional LED light fixture and the filler of aluminium base and lamp body contact portion, made the conduction of heat reduce flow process, effectively accelerated heat radiation; Led light source and electrical equipment line parts are positioned on the lamp body surface, directly need place the surface coverage circuit of light source at lamp body, hinder thereby add the circulation of having lacked heat conduction, have reduced technology, have increased production efficiency.Easy making process, cost are comparatively cheap, are applicable to commercial production in enormous quantities, install simply, and it is convenient to safeguard, is applicable to widespread adoption.
LED power supply of the present invention and Drive and Control Circuit are distributed on the inwall of lamp body shell; The electronic devices and components assembling wherein directly generates the control circuit unit; Thereby reduced heat-transfer path because electronic devices and components and lamp body become one, reduced thermal resistance, radiating effect significantly improves; And production technology is simplified greatly, and production efficiency significantly improves.
