Led panel light supply is ¬†well know as long time . Stable cold mild source, epoxy resin, light physique and no loose components, there isn’t any filament mild easy to burn, heat accumulation, gentle and rapid decline of errors errors, life of up to 50,000 to a 100,000 hours, longer life than typical light sources greater than 10 times. Drive energy requirements chip itself is lower than 0.5w, switching frequency necessities mandate larger than the 120hz, in order that while the prevalence frequency disturbance could be seen blinking.

Led panel light constructed-in driver IC chip bundle should help drive the short cooling die, if the die (die) within the copper binding on the indirect and indirect extension of a pin to bundle, straightforward to oblique welding in the pcb board thermal conductivity of copper rapidly (Figure 1). If the same 4x4mm silicon die on Britain to end eternal sub-300-1000ma of present, confirmed the power to determine the need heat the chip itself, the physical structure of cooling can be important.

Led panel light lamps on the low-voltage driver IC necessities:

1.Led panel light driver chip space which ought to be the nominal output voltage to meet the dc8-40v, use the realm to cover the needs of extra strain if larger than 45v; ac12v or 24v output complex with the bridge rectifier output voltage Energy voltage fluctuation, particularly at excessive voltage DC output voltage will be excessive if you cannot drive much less responsive ic extensive voltage areas, typically overstating the facility off when energy will be breakdown, led gentle supply additionally led to survival.

Led Panel light technical details of the trade-off lighting design is led panel light, led light source know-how more and more childish, LED lumens per watt has increased rapidly, rising year by yr to advertise its depreciated value. To 1wled light supply, for instance, the spring of 2008, the price is the price of one-third of the spring of 2006, spring 2009 to fall 2006 quarter.

Led panel light of high power: DC drive, extremely-low power (0.03 W -1 watt single tube) electro-optical power conversion verge of a hundred%, the identical light vitality than traditional lighting impact more than eighty%.

Lighting led panel light supply voltage could be very low vf, peculiar vf = 2.Seventy five-three.8v, if the 15-1400ma; which led drive the output voltage is vfxn ic, or vfx1, if constant within the 15-1400ma. Led panel light led light supply utilized in a small energy (if = 15-20ma) and power (if> 200ma)) two small energy led to do extra led fluorescent lamp, decorative lamp, grid lamps; power led to doing household lights, spotlights, underwater lights, wall lights, road lamps, pure gentle, automotive mission lights. Power led light supply is a low voltage, high current-driven device, the light intensity led by a present flowing by means of the scale of alternative, present too strong could cause attenuation of mild led panel light, led the current is too weak affect the luminous depth, thus, led the drive required to supply constant current power supply to Baoguan of energy led to make use of of Enron, while aspiring to realize luminous depth. Led lighting in the areas of vitality effectivity and lengthy life to replicate the traits of life, good display screen driver ic led panel light is essential, not a great driver ic’s matches, led panel light can’t replicate some great benefits of lighting.

2. Driver chips required is larger than the nominal output current 1.2-1.5a, because the lighting of the led light, 1w energy led mild of its nominal mission current 350ma, 3w power led mild of its nominal mission present 700ma, the necessity for more massive power present, which led driver ic lighting selected should have enough current output, design products to make the drive ic mission within the negative output of 70-ninety% over the best mission space. Use at full output present drive ic heat in poor lighting small spaces, simple deserting and late entry into drive.

Led panel light advantages of environmental safety: led is a kind of green mild, higher environmental advantages. Spectrum violet inside and pink paint is just not low in calories and no strobe, no radiation, and survival of absorption materials can be accepted, no clean components don’t contain mercury, chilly light source, you can safely contact, is a mannequin of inexperienced lighting.

. Driver IC’s personal anti-emi, musical, low strain may contact resistance to the whole success of Britain led lighting merchandise late ce, ul certification, which drive chip itself ought to use good beginning within the design of the topology of the production of low end negotiations process.

. Led panel light of the mass market and the necessity to proceed steady rise for several years would be the integrated circuit business, following vcd, dvd, mobile phones, mp3 funeral of battle after electronics market ultrasonic tsunami!

Led panel light was galloping development within the close to future, led a clear and green mild is broadly acknowledged. led light long life, energy saving, handy to make use of advanced, the usage of capital is low, so the household will receive a flood of gentle use, OSRAM optical semiconductor company in 2008 question statistics, the global annual family picture led panel light led the technical details of selection Block lamp lighting design ship is about 50 billion.

led driver chip to the inexperienced gentle to advertise progress of modern design, led lighting is inseparable from the drive chip, requiring a variety of features led light driver ic. led lamps use 36v AC energy supply can Hydraulic Fittings think of the next non-reduce off power supply, such as the use 220v and 100v AC energy provide lower off electricity payments thinking. Oblique use ac100-220v driver chip, the use of volume of luxurious, while the higher technical calls for, the higher the issue, now out in the due diligence to open up within the capital. Massive lighting needs of the market led to the success of all IC design corporations the opportunity once more, fast transformation, early merchandise, the chance to win lots.

led lighting Mission Features

three. Driver IC output present must be a life time constant, led to stable mild supply, light will not flash; the same variety of driver chips utilized in commonplace circumstances, the size of the output current might be divided to do, which is discrete to be small, in order that bulk lively production line can produce useful and orderly; for discrete output current has a particular must-driven chips at the manufacturing unit or manufacturing line earlier than the sub-file, the mediation board pcb present setting resistor (rs) of the impedance values, led to the manufacturing of light constant current led driver board on the identical gentle source luminance differences and maintain the ultimate product of divergent.

Led panel light of the high-vitality, long life, superior performance advantages of environmental safety have been recognized Centrifugal Fan all over.
