Description
Technical field
The present invention relates to a kind of LED light fixture, relate in particular to a kind of LED light fixture that utilizes ultrasonic wave heat radiation.
Background technology
As everyone knows, LED light fixture has advantages of that efficiency is high, the life-span long, energy-conserving and environment-protective, and its use is more and more extensive.LED light fixture is in the time lighting, and LED lamp pearl is changed visible ray into the electric energy of 30% left and right, and approximately 70% electric energy changes heat into, and therefore, LED light fixture can produce very large heat in the time lighting, and LED lamp pearl volume is little in addition, makes heat flow density large.If LED light fixture can not dissipate heat in time, can aggravate the light decay of LED lamp pearl, greatly shorten lamp life.
Current modal radiating mode is that according to the shape of the configuration design radiator of LED light fixture, metal material generally uses aluminium alloy conventionally for LED lamp pearl adds metal radiator, and for the ease of heat radiation, the material of printed circuit board (PCB) also adopts aluminium base conventionally.The heat that LED lamp pearl produces is dispersed into space outerpace after metal radiator derives again, and normally utilizes nature conduction, radiation and three kinds of forms of Natural Heat Convection, sometimes also adds that small fan utilizes forced convertion to dispel the heat.But, on the one hand, due to LED lamp interior narrow space, restrict the volume of fan, therefore can not produce very large air quantity, be difficult to ensure radiating effect; On the other hand, fan life is short, difficult mate with the LED life-span, and the noise of fan disturbs people, and these are all the defects of fan cooling.
Although certain thermolysis has been played in above-mentioned measure really, the effect of heat radiation is unsatisfactory, need to seek better radiating mode.
Summary of the invention
For above deficiency, the invention provides a kind of LED light fixture ultrasonic wave auxiliary heat dissipation, good heat dissipation effect that utilizes.
The present invention achieves the above object by following scheme:
A LED light fixture that utilizes ultrasonic wave heat radiation, comprises the LED light fixture that is provided with metal radiator, and LED light fixture has been embedded in supersonic generator.
Preferably, described supersonic generator comprises ultrasonic transducer, triode, multivibrator.
Further preferred, frequency of sound wave is higher, and in direction of sound propagation, in air, the vibration frequency of each particle is just higher, and the convection coefficient of air is larger, and therefore, described ultrasonic transducer is ultrasonic transducer more than frequency 100KHz.
Preferably, be provided with one or more lamp housing passages at lamp housing top.
Further preferred, on lamp pearl plate, be provided with one or more lamp pearl plate passages.
Further preferred, on plastic hoop, be provided with one or more plastic hoop passages.
Further preferred, described LED light fixture is bulb lamp.
The present invention will metal radiator as main radiator, adopt supersonic generator to carry out auxiliary heat dissipation, thereby the radiating effect of LED light fixture further strengthened.At present, ultrasonic transducer manufacturing process maturation, product variety is abundant, frequency having from tens of KHzs to hundreds of KHzs, volume is small and exquisite, the convenient LED lamp interior that embeds.
The present invention utilizes forced convertion that ultrasonic wave causes to improve the radiating effect of LED light fixture, at thermal source, place arranges supersonic generator, utilize ultrasonic wave energy to produce high-frequency vibration, strengthen the convection coefficient of air, change the physical state of propagation medium air, make air-dispersion effect stronger, air produces forced convertion, thereby heat is distributed.
The LED light fixture that utilizes ultrasonic wave heat radiation provided by the invention, the heat radiation for LED light fixture by ultrasonic technology that takes the lead in, facts have proved, its good heat dissipation effect, and easily realize.
