LED products are widely used in finance, advertising media, stadium, stage background, municipal engineering and other fields. It can be said that modern life cannot be separated from the application of LED, LED products are composed of many LED beads, LED products will be related to how to install and maintain LED bulbs. The following is a brief introduction.

LED lamp bead installation and maintenance and LED lamp bead selection guide

LED lamp bead installation and maintenance

     High power LED lamp installation

When we use LEDs, the driving current should not exceed the maximum specified current. It is best not to exceed 20mA. The recommended drive current is between 10-20mA and each LED has a different VF value. Therefore, when applying a real circuit, it is best to design lamps with similar VF values in the circuit to match different values. Resistance, in order to achieve the purpose of cross flow; Note that LED polarity should not be wrong, in general, the lamp foot slightly longer end is positive, slightly shorter is negative, if the two bare feet long, to carefully identify the mark.

When installing LED lamp beads, we should pay attention to the layout of external lines of various equipment to prevent polarity misalignment. The equipment should not be too close to the heating elements and the operating conditions should not exceed the specified limits. In case of pin deformation, it is important not to install the LED. When deciding to install in the hole, calculate the dimensions and tolerances of the holes on the surface and on the board to prevent the bracket from being subjected to excessive pressure. When installing LEDs, guide sleeves are recommended. The LED must be protected from any vibration or external forces until the welding temperature is restored to normal.
      Precautions for SMD LED lamp

LED bead has a variety of packaging forms, generally not outside the foot type and patch type, foot type can be perforated and welded on the circuit board, the back of the PCB circuit connection, insulation board can also be installed and fixed with the insulation board, and vice versa. The side of the foot is connected to the wire, and another SMD LED bead is attached and welded to the PCB. The surface of the PCB surface is composed of PCB circuits. High-power LED lamps also need to use high thermal conductivity aluminum based circuit board to HEA. T conduction. In addition, a radiator can be used to dissipate heat. Regardless of the type of lamp, LEDs need to use a constant current power supply to ensure a stable working state.

In the process of using LED lamp bead, we will encounter the situation that the lamp bead breaks. We need to repair and replace the LED lamp beads according to the actual situation.

1. If the LED power supply is damaged, buy the same parameters as voltage, current, etc., and replace it.
2. If the LED lamp is damaged more and the damaged LED patch lamp is concentrated in the same area, the damaged part can be cut off and re-welded.
3. If you have some basic knowledge of electronics, buy the same type of LED lamp, take the soldering iron and re-solder it. But again, there are many LED SMT components on each LED strip, one or two broken, which have little effect on the brightness.

In the LED lamp installation and maintenance problems, should take the corresponding measures according to the actual situation. For safety reasons, it is recommended to have the installation and maintenance performed by a professional. In use, we should not only consider the influence of the heat of LED itself on the lamp, but also consider the environmental temperature on the photoelectric performance of the lamp. Ringing.

LED lanterns are very familiar products in the LED industry. It can be composed of different LED products through various combinations. For many customers of LED products, we hope to buy high quality LED beads, to avoid the death of LED products and color difference, improve the life of the product, improve the competitiveness of the product. So, how to buy LED beads?
LED lamp bead selection guide

1. Look at the stand

There are aluminum brackets, brass brackets and copper brackets. Aluminum scaffolds have the worst heat conduction and the worst heat dissipation, followed by brass and copper. There's a lot of publicity in the market. Brass or adulterated copper may also be used.

2. Look at the chip
Look at the chip and the size of the chip, the quality of the chip also determines the quality of the beads, in general, the greater the stability of the chip, the stronger the brightness, the better the heat. This is the most important because the chip directly determines the color rendering index, brightness, and attenuation. This chip has domestic and Taiwan chip and imported chip (including the United States chip, Japanese chip, German chip, etc.). Different chips, the price is very different. Currently, the most expensive chips in the United States, followed by Japanese and German chips, are the least expensive chips in Taiwan with poor heat dissipation performance. What chip does it use? To what effect? Before you buy, you must remember.

3. Look at the welding production line
Welding wire is used to weld chips and brackets with gold wire, mainly depending on the quality of the gold wire. LED beads sometimes need to flicker, constantly lit, if the quality of the gold wire is poor, easy to burn out the dead light, the gold wire has alloy wire and pure gold wire, pure gold wire size is 0.7, 0.9, 1, 1.2, etc., and the quality is not the same, so also need to pay attention to.
4. See the brightness
The price of LED lights varies by brightness. There is a big price difference between regular brightness and bright LEDs. So, when you buy it, you have to know exactly what brightness you need, how much LM you can achieve, and LM as a measure of the brightness of the bead.

5. The color temperature
See whether the uniform color of the light is consistent, the quality of good light is very uniform, the color is consistent, which is related to the light splitor, there are many small packaging factories because there is no light splitor, so whether it is light separation, or external hair, so the quality is difficult to guarantee. LED has no chromatic aberration and poor color consistency. In the case of a poor bulb quality, a light bulb will appear that is on and off. Luminous color is not uniform, there will be obvious dark areas.

6.Look at the glue

Glue is made of domestic glue and imported glue. Encapsulated LED lamp beads do not deform the hand. If the quality of the glue is low, it will deform and even crack.

7. Look at the packaging technology

LED lamp packaging is divided into resin packaging and silicone packaging. Silicone packages have good heat dissipation and are slightly more expensive than resin packages. Packaging effect is closely related to packaging equipment. Good equipment to ensure the stability and consistency of products in a variety of procedures, to ensure the excellent rate of products.

The above introduction of the choice of LED lamp beads need to pay attention to, when it is difficult to identify the quality of LED lamp beads with materials, it is recommended to choose a regular, high visibility industry, strong manufacturers, product quality assured, and relatively safe after sale.
