LED Tube Light The Performance

Edit:Alite Co.,Ltd  Date:Aug 10, 2017

At present, LED daylight lamp Lighting market is more active, led drive power manufacturers are divided into 3 major types: The first is the development of the LED chip or LED lamp factory, the flow downstream infiltration; the second kind is the factory that does the ordinary lighting; LED Tube Light The third is the completely new factory that they used to do power or other products or new ventures.

LED Fluorescent lamp power is a very important part of LED fluorescent lamp, LED Tube Light if the choice is improper, LED fluorescent lamp can not play his due performance, and even may not be normal lighting use.

The characteristics of LED semiconductors determine that they are affected by the environment, such as temperature rise, led current will increase, voltage increase, led current will also increase. LED Tube Light Longer than rated current work, will greatly shorten the life of LED. And the LED constant flow is in the temperature and voltage and other environmental factors change, to ensure that the working current is unchanged.

Some customers design the lamp board first, find the power supply, LED Tube Light find it difficult to have a suitable power supply, either the current is too large, the voltage is too small (such as i>350ma, v<40v), or the current is too small, the voltage is too high (such as i<40ma, v>180v), LED Tube Light resulting in a serious fever, low efficiency, or insufficient input voltage range

In fact, choose the best string and connect the way, plus on each led voltage current is the same, and the effect of the power can play the best performance. LED Tube Light The best way is to communicate with the power supplier first, LED Tube Light tailor-made.

General led rated working current 20 ma Pui, some factories used to the beginning of the design 20 ma, in fact, the current work in the heat is very serious, after a number of contrast test, LED Tube Light designed to 17~19 Ampere is more ideal, recommended design for 18 Ma Pui.

The recommended working voltage of the general LED is 3. $number. 5V, tested, most of the work at 3.125V, so press 3.125V calculation is more reasonable. The total voltage of M-lamp beads in series $literal. 125*m.

To make the LED fluorescent lamp work in a wide range of input voltage (full voltage) ac85~265v, then the LED series-and-parallel mode of the lamp board is very important. Because the current power supply is generally not isolated step-down power supply, in the demand for wide voltage, LED Tube Light the output voltage should not exceed 72V, the input voltage range can reach 85~265v. That is, the concatenation count does not exceed 23 strings.

Not too many parallel numbers, LED Tube Light otherwise the working current is too big, the fever is serious, recommend 6 and/8 and/12 and. The total current does not exceed 240 ma-pei for good. There is also a wide voltage scheme, is to first use the l6561/7527 to raise the voltage to 400V, and then step-down, equivalent to two switching power supply, LED Tube Light cost 1 time times, this scheme is not high, there is no market.

General isolation of power supply such as 15W, placed in the LED lamp, its transformer volume is very large, difficult to put in. Especially for t6/t8 lamp, almost impossible, so the isolation of the general can only do 15W, more than 15W of little, and the price is very expensive. Therefore, LED Tube Light the isolation of the cost-effective, generally non-segregation of the mainstream more, the size can be done smaller, the smallest can be achieved high 8 mm, in fact, the non-segregation security measures are done, there is no problem.

Output power (output voltage * Output current/input power). LED Tube Light This parameter is particularly important if the low efficiency means that a large part of the input power is converted into heat emitting; if it is installed in the lamp tube will produce a very high temperature, LED Tube Light coupled with our LED light efficiency than the heat emitted, will be superimposed to produce a higher temperature.

And the life of all electronic parts in our power supply is shortened with the increase of temperature. So efficiency is the most fundamental factor to determine the power supply life, LED Tube Light the efficiency can not be too low, otherwise consumption in the power of the heat is too large. Generally above 80% can be, however, efficiency and light plate matching method.
