Description
Technical field:
This patent is the omnipotent special power supply of great power LED, is used for driving great power LED.Do not need retrieval, all do not have both at home and abroad at present.
One of background technology (electronic transformer):
First electric ballast is PHILIPS Co.'s development in the world.So someone is with the local circuit that just becomes electronic transformer of changing of the high-frequency oscillating circuits of electric ballast.
The main distinction of electronic transformer and electric ballast: in the one electronic transformer oscillation circuit without fluorescent tube.Adding around secondary coil on its two oscillating magnetic fluxs core crab is output, and the secondary coil number of turn is the reduction formula less than number of primary turns, otherwise is boost type.
The electronic transformer initial stage is mainly used on the neon sign electron transformer product.Neon lamp tube starting voltage and operating voltage are all very high.The secondary high pressure envelope curve circle number of turn is around getting a lot.Drag 12 meters long Ф, 10 caliber neon light tube electronic transformers, its power output is more than 120W, and primary coil is about 85 circles, and secondary high pressure envelope curve circle is about 3200 circles.And high voltage package connects neon light tube and can not open a way, in case open circuit, the epoxy resin moment spontaneous combustion of enamelled wire and encapsulation and burn out the components and parts such as the interior triode of electronic transformer in the high voltage package.
Recently during the last ten years because the extensive use of new light sources low-voltage halogen tungsten, such as the supporting demand of the halogen tungsten bulbs such as the 10W 20W 30W of specification 12V and 50W, so on the oscillating magnetic flux core coil again around on some circles, its output has just become the working power of tungsten halogen lamp.
Such as the halogen tungsten bulb of 24V, 250W, 300W, its electronic transformer is output as 12V and 24V in the high-power projecting apparatus of the usefulness of giving lessons, and is with a hand switch, and initial start 12V is manually switched to 24V operation work a moment later.Can not burn out too greatly 250W, 300W halogen tungsten bulb and electronic transformer because of starting current like this.
Because the electronic transformer circuit is simple, production cost is low, and technology maturity is the same with electric ballast, so be widely used.The useful life of electronic transformer also should be much longer than the useful life of electric ballast, because in the electronic energy-saving lamp fluorescent lamp there be in the oscillation circuit of tube filament string, filament one is bad, and electric ballast also is burned simultaneously.
Two (great power LEDs) of background technology
Over nearest six, seven years, the LED development is very fast, and production technology is also more and more improved advanced.High-power LED chip has 1W and above.
High-power LED lamp is expensive, and general common 12PCS is 12W, and price is about 50-70 unit.The LED light fixture comprises three parts, i.e. LED aluminium base, driving power plate and shell aluminium alloy heating panel thereof.
The power drives plate, its kind description is also Duoed also complicated than the electronic transformer electric ballast.Some producer constant-current source driving LED, constant-current driving power supply plate price straight line rises so.Moreover powerful constant-current source energy ably done such as capacity such as 20W, 50W, 100W? is its volume weight price again how much? although the LED development speed is very fast, also do not resemble and be used widely the electronic energy-saving lamp fluorescent lamp, its basic reason, expensive.And the shared production cost share of driving power plate is very large!
Summary of the invention
The purpose of its invention: because high-power LED driving power source (plate) is too expensive at present, can adopt prior art and new departure to substitute.Driving power (plate) price straight line descends, and this patent universal type special power supply is the scheme of excellent the best, pioneering scheme.
New technical scheme: in brief, be direct current by rectification again with the high-frequency alternating current of electronic transformer output, drive and light LED.
Description of drawings
Fig. 1: square frame DB represents commercially available electronic transformer.A and B represent power frequency 50-60Hz, the alternating current input of 110-277V.(is there 110V in Japan? China 220V, West Europe 240V and even 277V peak voltage).C is that high frequency square wave exchanges output with D, again through D
1-D
4Diode rectification is direct current.Only drawing two groups of LED meters 4 minutes among the figure is connected in the circuit loop.Electronic transformer is jumbo words, can drive the LED of 300W.The LED number of elements can not limit, but combination in any and connection in series-parallel.
