Abstract
The utility model relates to a multiplex drive LED light belonging to a light with LED as light source, which utilizes a drive circuit to drive a plurality of LED lights. A drive power source is connected with more than two resistors in parallel. Each resistor string with parallel connection is connected with more than two LED lights. It is proposed to arrange the output drive voltage of the drive from 9.8V to 14.8V. The utility model outputs basically constant voltage and current, which will not increase due to the input voltage rise, thus slowing LED aging speed and prolonging LED service life. The utility model has the advantages of higher electrical-to-optical converting efficiency, stability, luminance, LED heat radiation, etc. compared with circuits without drives, hence saving more electric power.
Description
Technical field:
The utility model relates to illuminator lamp, especially adopts the illuminator lamp of LED as light source.
Background technology:
At present, Chang Yong semiconductor lamp is divided into two kinds of high-power and small-powers.All must be behind power conversion by supply convertor, for light-emitting diode provides stable unidirectional drive electric current, guarantee that luminous tube works under than higher luminous efficiency and lower light decay.
Make semiconductor lamp with large-power light-emitting diodes and can use the AP-2B320 driver, this driver is powered with 220 volts of electric mains, provide 320mA stable unidirectional current to light-emitting diode, can contact drives only 1 watt large-power light-emitting diodes work of 10----40.Be fit to make 10-40 watt semiconductor lamp.This driver uses the stability of high-frequency convertor technology maintenance output current, the efficient height, and volume is little.This driver is a modular construction, no peripheral component.
The light-emitting diode that adopts large-power light-emitting diodes making semiconductor lamp to use is few, does not have peripheral component, and is simple in structure, makes easily.But the large-power light-emitting diodes price is higher relatively at present, therefore, and the cost height of lamp.
The pipe number of using with low power LED making high power semi-conductor lamp is a lot, so will use the series/parallel structure.Two kinds of reasonable technical schemes are arranged at present:
First kind of scheme is to use the ZL-220V/0.5A rectifier with the electric main rectifying and wave-filtering, re-uses a plurality of driver drives luminous tubes.Driver is special-purpose low power LED driver, uses the stability of high-frequency convertor technology maintenance output current, the efficient height, and volume is little.High voltage direct current power supply, input voltage range are that direct current 240-350 lies prostrate, and the output of 72mA unidirectional current can in parallelly drive 4 string low power LEDs, and every string tandem tube number is 5-50, drives 200 small-power luminous tubes at most.This driver is a modular construction, and 4 lead-in wires are arranged, and two lines connect power supply, two line sending and receiving light pipes.Energising gets final product work.
The power of small-power luminous tube input has only about 50 milliwatts, need be with 600 low power LEDs, 3 drivers of 600 small-power luminous tubes needs if make 30 watts semiconductor lamp.The rectifier that also will join the filtering of a band in addition.Because input current is little, supporting rectifier continuous operation electric current gets final product greater than 300mA.
Another kind of scheme is to use the aforesaid driver 18--20 of driving string directly in parallel small-power luminous tube, and every string pipe is only counted 10--50.Can be with 1000 small-power luminous tubes at most.
The structure of this scheme lamp is simpler, and cost is also low than the scheme that adds rectifier with a plurality of small-power drivers.
Because luminous tube during fabrication also can not be just the same with a kind of cast forward voltage drop, and the tube voltage drop of light-emitting diode has negative temperature coefficient, electric current when this can cause in parallel use of many string luminous tubes between each string is inconsistent, therefore, go here and there luminous tube every string light-emitting diode resistance of will connecting that uses in parallel goes here and there electric current between the luminous tube with balance more.
The components and parts that the small-power luminous tube is manufactured the use of high power semi-conductor lamp are many, complex structure, assembling trouble.But because small-power luminous tube price is low, the production cost of lamp is low.
This no driver module circuit is along with the rising of input voltage, and circuit voltage, electric current, power, LED illumination is also along with rising, stable extreme difference.
Summary of the invention:
The purpose of this utility model is: the LED illuminating lamp that the multichannel that provides drive circuit of a kind of usefulness to drive the driving of LED multi-path lamp simultaneously drives.
It drives many group LED lamps by a drive circuit; Its circuit adopts following electrical connection: 1 pin of integrated circuit (IC) connects the end of R3, C1, C2, fuse F1, do 4 pin of IC connect R4, C5, R6, R7, C3, C? an end, 5 pin of IC connect the other end of R4,6 pin of IC connect the other end of R3, the end of the negative pole of 7 pin, the 8 pin connection D1 of IC, inductance L 1, R5, the other end of R5 connects the end of C4, the other end of L1 connect the other end, the J2 of an end, C5, the R6 of C6, C7 1 pin, 2 pin ,+the 10.4V power supply, 3,4 pin of J1 connect the other end of VCC12V-16V power supply, F1; 1 pin, 2 pin of J1,3 pin, 4 pin of J2, C6, C7, R7, C4, C3, C1, C2, C? the other end, the positive pole of D1,2, the 3 pin ground connection of IC; + 1 0.4V driving power R1-Rn resistance in parallel; The other end of R1-Rn resistance D1-Dn the LED lamp ground connection that just is being in series again.
