FAQ

The difference between high voltage and low voltage LED light belts

Low voltage lamp with 12V and 24V, 12V low voltage work, step-down instability, leading to the front and rear light uneven.24V step-down stabilization. Uniform brightness. Long service life. It is recommended to use 24V light belt.

What are the specifications of the LED lamp band and which ones are more commonly used?

LED lamp belt is divided into flexible LED light band and LED hard light strip two kinds, but generally also contain wire to connect LED old lamp belt, such as flat three wire, 4.3W/ meters, flat four lines, 6.48W/ meters, flat five line, 8.64W/ meters, lamp belt and so on.

How do you fix the LED band when you step on the stone?

First, put the lamp belt trough on the marble surface, then the LED lamp is then put into the lamp belt trough. This method is suitable for the occasion that needs LED lamp belt to be fixed to marble for a long time;

How to distinguish between colorful LED lamp band and RGB lamp band?

Definition: RGB lamp with RGB lamp belt refers to each LED LED lamp belt welding is composed of red, green and blue three chips, they can emit red, green and blue three kinds of monochromatic light can shine together three chips, combined into white. If coupled with the controller, you can achieve red, green, blue, white four colors in turn and flicker effect. RGB means red, green and blue. It doesn't represent colorful.

Led how much is the band of light a metre?

With a LED lamp, SMD3528/5050 lamp light source is, the more expensive 20-30/ meters

Troubleshooting of LED light belt

Mainly from the following aspects to identify:1, look at solder joints. Regular LED lamp manufacturers with LED light band produced by SMT patch process, produced by solder paste and reflow soldering. Therefore, the solder joint on the LED light band is smoother and the solder flux is not much, and the solder joint is in an arc shape extending from the FPC pad to the LED electrode.2, look at the quality of FPC. FPC points of copper and rolled copper two kinds, copper plate copper is protruding out, look carefully, from the pad and FPC connection to see. The rolling copper is closely connected with FPC, and can be bent at any time without the phenomenon of pad falling off. If the copper plate is bent too much, the pad will fall off and the temperature will be too high to cause the pad to fall off.3. Look at the cleanliness of the surface of the LED lamp. LED band produced by SMT process, its surface cleanness is very good, can not see what impurities and stains. Hand soldering process to produce a cottage version of the LED lamp band, no matter how the surface cleaning, will remain stains and traces of cleaning.4. Look at the packing. The regular LED lamp belt will be packed with an antistatic coil tray, 5 meters roll or 10 meters roll, and the outer packing will be sealed with anti-static moisture proof packing bag. LED version of the cottage version of the band with recycled reel, there is no anti-static moisture-proof package, a closer look at the reel, you can see the appearance of cleaning labels left traces and scratches.5. Look at the label. Regular LED lights, bags and rolls have printed labels, not printed labels.6, look at the attachment. LED lamp with formal will attach instructions and specifications in the lights inside the boxes, also equipped with LED lights with a connector or card holder; not the accessories and LED lamp with copycat version of the box, because some manufacturers still can be saved.

LED soft light belt?

Note: the installation of the LED lamp with LED lamp belt compared to traditional lighting, or are in the development of new products, so many consumers on how to install the LED lamp belt is not very understanding, in the installation process may occur in a variety of problems led lights with LED can not be used, the correct use and installation of the LED lamp belt extend the LED lamp with life, we also need to understand the problem. LED lamp belt at the time of installation, must be in accordance with the concise, use the correct method to carry out the installation, if excessive distortion or incorrect use of the installation method, are easy to light with losses, reduce the lamp with the use of time, is not conducive to the maintenance of the lights.

How about the wattage of the hidden LED lamp belt?

The LED has different chips that cause different currents. For example: there are 0.011A; 0.015A; 0.028A and so on, it should be said that different batches of LED chip will have different values of the current, so each batch should be measured by instruments. In general, the 30 light / meter band will use a larger current of LED. For example: 0.028A, calculate the power per meter (30 / 3: lamp lamp group) * (12V * 0.028A) =3.36W; and 60 meters of lamp / lamp with LED will use less current to produce, for example: 0.011A, calculate the power per meter (60 / 3: lamp lamp group (x) 12V * 0.011A =2.64W). The use of resistance but also according to your current input voltage and depending on LED, because LED rated current is 20MA, but the actual application generally do not use 20MA, usually 15--18MA! To the series resistance, by Ohm's law can be counted by U=IR.
