FAQ

Waterproof LED lamp belt used after a period of time, there is a part of the lamp with white into orange, what's the matter?
Waterproof lamp with 3 waterproof glue, waterproof casing, gluewaterproof.The three lights in the process of using the glue properties will produce oxidation, with epoxy glue, glue, glue sleeve.After the oxidation may have a slight color, slightly yellow, light color after visual orange emission through the surface of the glue in may.
Why does the length of the LED band fade with length?
When the supply current increases, the internal resistance remains unchanged, resulting in a decrease in the output voltage. The LED and resistance of the light belt are fixed. So the current will be small
What is the material of LED lamp belt?
Sort:LED lights are divided into two types of flexible LED lamp band and LED hard light strip, but they also contain the old band with wire connecting LED, such as flat three wire, flat four wire band and so on.Difference:1, flexible LED light strip is done using FPC assembly line board, with patch LED assembly, the thickness of only one coin thickness, Mitutoyo LED lamp with space; general specifications 30cm 18 LED, 24 LED and 15 LED 50cm long, 24 LED, 30 a LED. There are 60cm, 80cm and so on, different users have different specifications. The utility model can be cut at will, and can be extended at any time, and the luminous effect is not affected. The FPC material is flexible and can be bent, folded and wound freely. It can be moved and stretched freely in three-dimensional space without breaking. The utility model is suitable for irregular places and space narrow places, and can also be arbitrarily bent and winding, and is suitable for arbitrarily combining various patterns in advertisement decoration.2, LED light bar is PCB hard to do assembly circuit board, LED SMD LED assembly useful, but also useful in line LED assembly, as required by different components and different. The advantage of hard light bar is easier to fix, and the processing and installation are more convenient. The disadvantage is that it can not bend freely and is not suitable for irregular place. Light bar with patch LED with 18 LED, 24 LED, 30 LED, 36 LED, 40 LED and so on many kinds of specifications; used in line LED 18 star, 24 star, 36 star, 48 stars of different specifications, also have a positive side, and side light called the Great Wall lights.
Is the LED belt with a constant voltage transformer or a constant current transformer?
LED lights with all kinds of varieties, with high and medium pressure, low voltage, AC and DC, lamp with internal general only by the current limiting resistor to protect the LED chip, is not reliable, of course, preferably with constant current drive lights, but seldom have this right drive, generally uses the switching power supply has regulated performance they are very sensitive to the change of the LED drive, the power supply voltage, the voltage variation of the weak will bring great changes in current, exceed the rated current of LED is very easy to damage. So the requirements of power supply better performance (in order to avoid the current instability), a better solution is to lower the power supply output voltage, the LED voltage derating, even if the impact is not accidental, overcurrent, caused damage to the LED, such as the low voltage of 12V can be adjusted to use low 11.5V. This will extend the service life.
LED light is still a weak light after the switch is closed. What's the matter?
LED has normal light after power failure. The solution is...1, with a grounding wire, you can understand?2, test pencil, measure will be changed to FireWire, FireWire disconnection switch circuit3, in the case of unprofessional, use method 1
Which is good for low voltage lamp belts 5050 and 3014?
1, indoor installation: LED lights for indoor decoration, because of not having to undergo the installation is very simple so exposed to wind and rain. The LED lamp Guanghong electronic production zone as an example, behind each LED lamp belt are affixed with self-adhesive 3M double-sided adhesive, the installation can be directly off the surface of the 3M double-sided adhesive stickers, and then the lamp strip is fixed on the installation place, by hand press flat on the line. If some places need a corner or a long range, simply put the LED band into 3 groups of LED in series and parallel form, because every 3 LED can be cut and used separately.2, outdoor installation: outdoor installation due to withstand wind and rain, if using 3M glue to fix, a long time will cause the decrease of the 3M adhesive LED lights off, so often used for outdoor installation fixed card slot, need to cut and connected place, method and indoor installation, but also need to equipped with waterproof glue, waterproof effect to consolidate the connection point.
LED current increases beyond 20MA, or when 30MA-50MA has consequences for LED lights?
The high power LED does not matter, but the straw hat, like 5mm small LED lamp is fatal, usually these small LED rated current is 20mA, a do make it work on the 15--18ma, you need to 30MA-50MA, it is early light oh, quickly over the
How much is the output voltage of the LED lamp belt driver?
3V to 36V, more LED products technical problems, consult the selected lighting
