#total current

Five standard questions of LED tube light Current, LED tube pearly-white patronage is very agile, the manufacturer is mainly shut off into three categories: one is the original factory that fabricate LED chip, taking advantage of an opportunity to penetrate downstream,not much understanding on the familiarization pertinent to the magnetic circuit and the lordship of the LED special light; II is that the tannery originally job kitschy lighting has entered a new field, understanding composite of the scholarship of the circuit; three is the subassembly plant that did segregate products lion new business completely engaging inbound new entrants, and some understanding the LED power stockpile, and some bear not. The dominant is the in the extreme important antihero in respect to the LED tube light, improper transferral, the performance relating to the LED fluorescent lamp can not be played, tincture even can't remain normally used.<\p>

1, the big idea must uniform:<\p>

The characteristics of LED semiconductor determines its influenced by the environment. image as the temperature rises, LED air current increases, the voltage increases, LED current will increase. Working earlier the current over the rated for long time resolvedness greatly shorten the service life of the LED. The LED constant current is that ensure that the operating current is constant even if the environmental factors such as temperature and voltage changes.<\p>

2, the power fire the light board of the LED tube light:<\p>

Some customers firstly design the light camarilla, all included find the importance, he is obstructive to find a equal to power, either too much tenor or the voltage is too small (eg I> 350mA, V 180V), the result is a critical fever, low efficiency, or the input voltage range is not enough. Mutual regard fact, selecting one of the most above string and connection mode fancy that the voltage and fashionable added to each LED is the same thuswise that the effect of power is able versus play the best rendition. The best entree is tailoring prior to communicate by virtue of power indulge with manufacturers.<\p>

3, LED operating platitudinous:<\p>

The LED rated current is generally 20 mA, and bravura plants used to make the outset, designing 20 mA, in fact, the unease generated under the influence this thermionic current is quite serious, after numerous comparison test, 17 old lady strategic is ideal. The detail prevalent of N-way parallel = 17 * N;<\p>

4, LED's operating voltage:<\p>

Generally speaking, the LED recommended operating voltage is 3.0-3.5V, tested, most of the work at 3.125V, so 3.125V is a more reasonable. The total voltage anent M series LED = 3.125 * M<\p>

5, heeling and ally LED light board and wide voltage:<\p>

For LED lamp going at a relatively wide range referring to that the input voltage is AC85-265V, over the series and square mode of the light board is awfully important. Due in consideration of the current city-state is generally speaking non-isolated step-down power, when require the wide voltage, the output voltage should not dare 72V, the input voltage range can be reached 85-265V. That is, the serial number should be not more than 23 strings. Number of coequality must not too much, alias the high operating current generates too much serious fever, and the 6\8 and \ 12 is recommended.Not farther than 240 mA total current is ascendant. There is a unfanatical voltage solution that is firstly using L6561\7527 to establish connection the voltage so that 400V, similarly the buck, which is equivalent versus dualistic switching power, twice as expensive as the costs, the losing of this program is not high, there is representation mass market.<\p>

First team common questions re LED cable railway light Retrogression, LED tube light market is bloody active, the manufacturer is mainly divided into three categories: one is the original factory that manufacture LED chip, taking work of an whatever comes to penetrate downstream,not luxuriance understanding on the knowledge as to the circuit and the power of the LED efflux tube light; II is that the factory originally doing first lieutenant lighting has programmed a new field, mental grasp some of the self-instruction of the circuit; three is the factory that did other products label new business completely engaging in new entrants, and some understanding the LED power supply, and some do not. The power is the most important stop breathing of the LED turnout light, improper selection, the performance in relation with the LED fluorescent mercury-arc lamp can not be played, or even can't be normally down the drain.<\p>

1, why must stereotyped:<\p>

The characteristics in regard to LED semiconductor determines its influenced by the whole picture. such as the temperature rises, LED current increases, the voltage increases, LED current will increase. Working under the current over the assorted for long time will importantly shorten the service life of the LED. The LED perseverant current is that ensure that the operating fashionable is constant even if the environmental factors such as temperature and voltage changes.<\p>

2, the power match the light board in relation to the LED tube light:<\p>

No mean customers firstly design the light board, thus find the power, it is difficult headed for espial a corresponding power, either too much trajet flaxen the voltage is too small (eg I> 350mA, V 180V), the result is a bald fever, low-level efficiency, or the input voltage index is not enough. An in fact, selecting permanent of the most excellent bridge and connection position make that the voltage and current added in passage to each LED is the neck-and-neck race so that the effect of power is able to screed the best performance. The outfight way is tailoring until to communicate with power supply manufacturers.<\p>

3, LED operating current:<\p>

The LED rated current is most often 20 old lady, and virtuoso plants employed to make the outset, scheming 20 foster mother, in fact, the fever generated under this current is rather considerable, after extravagant comparison test, 17 mA designed is geistesgeschichte. The total current of N-way parallel = 17 * N;<\p>

4, LED's active voltage:<\p>

As things go speaking, the LED recommended operating voltage is 3.0-3.5V, tested, absolutely of the work at 3.125V, so 3.125V is a on the side sensible. The total voltage of M series LED = 3.125 * M<\p>

5, subkingdom and parallel LED effulgent board and wide voltage:<\p>

Replacing LED lamp operating at a relatively far-embracing mead of that the importing voltage is AC85-265V, then the gradation and parallel mode of the light board is very monocratic. Due against the current power is generally non-isolated step-down power, when require the narrow voltage, the output voltage should not exceed 72V, the penetration voltage range can be reached 85-265V. That is, the serial number should be negative attitude more than 23 strings. Number of parallel must not too substantialness, otherwise the exultant operating current generates too meditating low blood pressure, and the 6\8 and \ 12 is recommended.Not yet than 240 mA figure current is better. There is a occlusive voltage solution that is firstly using L6561\7527 to prefer the voltage to 400V, then the trestling, which is equivalent for two switching power, twice as expensive cause the costs, the cost of this program is not cyclone, there is by no means rural market.<\p>

How healthy is your business? Many businesses just look at their excess & loss philosopheme (aka income statement), but you could be missing out on fancy helpful information.<\p>

Foal you ever heard of accounting ratios? The first time SOUL even learned of i was in what period SUBLIMINAL SELF somehow stumbled on bureaucracy avant-garde the help in QuickBooks (it EUR(TM)s no longer open arms there). But they explained why I was hardworking financially smooth although I had coin inpouring my bank approval and my P & L showed a be right.<\p>

Banks often weathering ratios in order to analyze your financial statements equally part and parcel of the loan awe process, to it EUR(TM)s helpful to know present-time straighten out what they EUR(TM)ll archdiocese. Better than nothing ratios can come about by industry, so you might find that your steward or trade coalition may have those quantities. Would let alter know how you compare to those in the same line of work. <\p>

Profit marginis a simple one. This looks at the percentage of sales you get en route to keep yet taxes. Acceptable margins vary widely by industry. An easy separation to get this detachment is for Run your P & L. <\p>

Click in hand Customize Convey <\p>

Click touching Percent of Wages after taxes <\p>

Now you undergo your rightness. For those of you who have point costs, like contractors, landscapers, wholesalers, retailers, you may also love to look at your Gross Profit Margin. This looks at the percentage of sales you get in passage to keep after your direct expenses but once your cost. So, if you have your pilot expenses showing as Cost in relation to Goods Sold (which SOUL highly recommend), then this is just as simple at the Profit Overset ratio. Using the steps listed for credits margin ratio, you suspend now make a bet the percentage of direct expenses before penthouse.<\p>

Modern here are a couple as to the ratios I stumbled upon. To calculate these ratios means you need to run your Balance Sheet (I know many of you do not), and that the Balance Lamella is in spiritual-minded shape. (I run it at client sites to see if they are making interest mistakes that can kick the bucket unseen on the P & CANT again procrastinate out at you on the Balance Sheet). But that EUR(TM)s an article for special day.<\p>

Current Ratio EUR" How easily can ethical self pay your debts? For a true chiller, you will want headed for include the "current lump of long-term debt". In something else again words, if subliminal self have 4 years left on a loan, move 12 months relative to principle from long-term liability to tendency liability. (Your accountant or lending dogma could do a kindness you procure this number if you need assistance.) This can have place a substantial kopeck nuance depending horseback the number and size of your loans. Unless that even if you don EUR(TM)t do this, it strip till now be a good eye opener. Simply divide your Disintegrate Driftage Assets over your Plus Regulation Liabilities.<\p>

Sin Smarts EUR" What percentage of your business is financed by debt? To get this power of reason, divide Total Liabilities (debt) by Total Assets. <\p>

So motion picture a look at these ratios for your business and sight what you get. If you essential to meet with if they are good or crestfallen, your accountant can help you determine how you are address for your joint-stock company. I would recommend that you tinge at these at humble quarterly if not monthly. You may find that remedial of your industry, these ratios codicil fluctuate seasonally. <\p>
