Description
Technical field
The present invention relates to the electrical lighting light fixture, the long-lived great-power electronic lighting of particularly a kind of efficient energy-saving.
Background technology
LED (light emitting diode) is a kind of semiconductor devices of solid, and it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, is that entire wafer is by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form one " P-N knot " between them.When electric current will send energy with the form of photon then by lead, the luminous principle of LED that Here it is, and the color of light wavelength decision light determines by forming P-N knot material.
Main feature: characteristics such as the application LED light fixture of LED lamp display screen, traffic signal display light source has that antidetonation is shock-resistant, speed of photoresponse is fast, power saving, reliability height and life-span are long are widely used in various indoor, outdoor display screens.The at present direct target of LED lamp is led light source replace incandescent and fluorescent lamp, and this alternative trend has begun development from the topical application field.Can save several hundred billion and rise the energy of crude oil every year, and can reduce the generation of carbon dioxide and other greenhouse gases.The indoor photograph of family expenses the LED product come more welcome, the LED Down lamp, the LED Ceiling light, the LED fluorescent lamp, LED optical fiber lamp enters family stealthily! LED is encapsulated in the epoxy resin the inside fully, and is all firmer than bulb and fluorescent tube.Do not have loosening part in the lamp body yet, make LED not fragile.Led light source can utilize the red, green, blue principle of three primary colours, realizes colourful dynamic change effect and various image.But along with the power of LED lamp increases, the heat dissipation problem of existing LED lamp technology can not get solving, and semiconductor devices can not be kept operate as normal, thereby has limited the development of high-powered LED lamp.
HF lamp without electrodes is the novel light source of high-tech that integrates up-to-date electronics power-saving technique and electric light source technology, and it adopts magnetic field to come energizing gas discharge, luminous without filament.HF lamp without electrodes is made up of excitation power supply, power coupler and bulb three parts, and driving source produces the above electricity of 2MHz electric current frequently, and it delivers to power coupler through feeder line.When the electronics of high frequency electric by bubble internal discharge space quickened by electric field, when energy reaches certain value, bump with gas molecule in the container, the gas avalanche ionization forms plasma in the bulb.When the plasma excited atom is returned ground state, spontaneous ejaculation ultraviolet light, it excites the fluorescent material on the bulb walls to send visible light.
Main feature: electrodeless in the electrodeless lamp, the life-span with overlength.Good energy-conserving effect.The luminous efficiency height.Flicker free helps vision health.Start and restart superior performance, can instantaneously light.High-color rendering can be applicable to all kinds of places.The reliability requirement that is particluarly suitable for throwing light on is higher, needs long-term illumination and the place of keeping in repair, change the light fixture difficulty is used.
Road as from the foregoing, HF lamp without electrodes needs an electromagnetic field of high frequency to come activated plasma, and high frequency magnetic field is produced by power coupler, the power-conversion efficiencies of power coupler has also directly determined the Energy Efficiency Ratio of HF lamp without electrodes in addition, so the quality of power coupler is one of key problem in technology of HF lamp without electrodes.Power coupler itself is the inductor of high frequency oscillation circuit, both is made of lead institute on the soft magnetic ferrite.Hence one can see that, and the power-conversion efficiencies of power coupler mainly is subjected to the influence of soft magnetic ferrite electromagnetic property.
Current, external general employing 3F4 power manganese-zinc ferrite is applied to prepare the power coupler in the HF lamp without electrodes, its resistivity is lower usually, and this causes ferritic eddy-current loss sharply to rise because the operating frequency of HF lamp without electrodes is generally 2.5～3MHZ, thereby greatly reduces the efficient of light fixture.In addition, eddy-current loss by the fourth manganese-zinc ferrite is very big, and eddy-current loss mainly is converted into heat, this causes ferritic in the course of the work temperature can reach 100 unexpectedly " more than the C; thus make the power manganese-zinc ferrite in the assembling power coupler, just must will carry out special insulation processing and skeleton support; cause technology comparatively complicated, increased production cost.
Simultaneously since electrodeless lamp is born, heat dissipation problem just is accompanied by it always, and HF lamp without electrodes is along with power is increasing, and prior art exists heat dissipation problem more and more outstanding, a large amount of heats that power coupler produces can not in time distribute, and cause the magnetic core temperature to surpass Curie point and lose efficacy.At present typical technical scheme is that coupler magnetic core and higher temperature line produce high frequency magnetic field, and the unnecessary heat energy that coil produces is transmitted to the aluminum base outside by the copper heat conductive rod or the heat pipe of centre.Base has two kinds of functions: the one, guarantee being connected of bulb and coupler; The 2nd, unnecessary heat is passed to fin or light fixture.Such structure thermal contact resistance is big, and the space is narrow and small, and heat flux is little, complex structure, and the power of doing maximumly in the market bubble shape 185w, annular 210w, thus limited the application of LED lamp HF lamp without electrodes.
