Led Tube: Led panel mild source is called lengthy life lamp. Stable cold mild supply, epoxy resin, mild physique and no loose components, there isn't any filament gentle easy to burn, heat accumulation, mild and rapid decline of errors errors, life of up to 50,000 to 100,000 hours, longer life than conventional light sources greater than 10 instances. Drive energy requirements chip itself is lower than zero.5w, switching frequency requirements mandate greater than the 120hz, in order that while the incidence frequency disturbance can be seen blinking.
Led panel light built-in driver IC chip package ought to help drive the quick cooling die, if the die (die) within the copper binding on the indirect and indirect extension of a pin to package, straightforward to indirect welding within the pcb board thermal conductivity of copper rapidly (Figure 1). If a similar 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 bodily structure of cooling can be essential.
Led panel mild lamps on the low-voltage driver IC requirements:
1.Led panel gentle 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 pressure if better than 45v; ac12v or 24v output complex with the bridge rectifier output voltage Power voltage fluctuation, especially at high voltage DC output voltage can be high if you cannot drive much less responsive ic extensive voltage areas, usually overstating the ability off when energy might be breakdown, led gentle source additionally led to survival.
Led Panel gentle technical particulars of the commerce-off lighting design is led panel light, led gentle source know-how more and more childish, LED lumens per watt has increased quickly, growing yr by 12 months to advertise its depreciated worth. To 1wled gentle source, for example, the spring of 2008, the value is the price of one-third of the spring of 2006, spring 2009 to fall 2006 quarter.
Led panel gentle of high energy: DC drive, extremely-low energy (zero.03 W -1 watt single tube) electro-optical energy conversion verge of a hundred%, the identical light energy than conventional lighting impact more than 80%.
Lighting led panel mild supply voltage is very low vf, strange vf = 2.Seventy five-three.8v, if the 15-1400ma; which led drive the output voltage is vfxn ic, or vfx1, if constant in the 15-1400ma. Led panel mild led mild source utilized in a small power (if = 15-20ma) and energy (if> 200ma)) two small power led to do more led fluorescent lamp, decorative lamp, grid lamps; energy led to doing family lights, spotlights, underwater lights, wall lights, road lamps, pure gentle, automotive mission lights. Power led mild supply is a low voltage, high current-pushed gadget, the sunshine depth led by a present flowing through the scale of selection, present too sturdy may cause attenuation of gentle led panel gentle, led the present is too weak have an effect on the luminous intensity, thus, led the drive required to provide constant current power supply to Baoguan of energy led to make use of of Enron, while aspiring to achieve luminous depth. Led lighting in the areas of energy effectivity and long life to replicate the traits of life, good display driver ic led panel light is crucial, not a good driver ic's matches, led panel gentle cannot replicate the benefits of lighting.
2 x 2 led panel lighting [www.loevet.com]. Driver chips required is better than the nominal output current 1.2-1.5a, as the lighting of the led light, 1w power led mild of its nominal mission current 350ma, 3w power led light of its nominal mission current 700ma, the necessity for more giant energy current, which led driver ic lighting selected must have sufficient present output, design products to make the drive ic mission in the adverse output of 70-ninety% over the most effective mission space. Use at full output current drive ic heat in poor lighting small areas, easy deserting and late entry into power.
Led panel light benefits of environmental protection: led is a kind of green gentle, higher environmental advantages. Spectrum violet inside and purple paint is not low in calories and no strobe, no radiation, and survival of absorption materials might be accepted, no clean components do not contain mercury, chilly light source, you can safely touch, is a mannequin of green lighting.
. Driver IC's own anti-emi, musical, low pressure can also contact resistance to the whole success of Britain 1x4 led panel light 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 need to continue steady rise for several years will be the integrated circuit industry, following vcd, dvd, cellphones, mp3 funeral of battle after electronics market ultrasonic tsunami!
Led panel gentle was galloping progress within the near future, led a clear and green gentle is extensively recognized. led light long life, energy saving, handy to use advanced, the usage of capital is low, so the family will obtain a flood of mild use, OSRAM optical semiconductor company in 2008 query statistics, the global annual family photo led panel light led the technical details of choice Block lamp lighting design ship is about 50 billion.
led driver chip to the green mild to advertise progress of progressive design, led lighting is inseparable from the drive chip, requiring quite a lot of functions led light driver ic. led lamps use 36v AC power supply can Hydraulic Fittings consider the following non-minimize off energy supply, such as the use 220v and 100v AC energy supply reduce off electricity bills considering. Oblique use ac100-220v driver chip, the use of volume of luxury, while the upper technical demands, the higher the problem, now out in the due diligence to open up in the capital. Huge lighting needs of the market led to the success of all IC design companies the opportunity once more, fast transformation, early merchandise, the opportunity to win heaps.
led lighting Mission Options
three. Driver IC output current should be a life time fixed, led to stable mild source, mild will not flash; the identical number of driver chips used in normal circumstances, the size of the output current will be divided to do, which is discrete to be small, in order that bulk energetic manufacturing line can produce helpful and orderly; for discrete output current has a particular should-pushed chips at the manufacturing unit or manufacturing line before the sub-file, the mediation board pcb present setting resistor (rs) of the impedance values, led to the production of mild constant current led driver board on the identical gentle supply luminance variations and maintain the ultimate product of divergent.
