With the rapid development of representative electronic products such as intelligent communication, 5G Internet, and digital electronics, basic electronic components have entered a stage of faster transformation and development. The LED SMD lamp beads produced by Hongfucheng Optoelectronics are also favored in the field of electronic products, especially the 3528 Symphony LED SMD lamp beads have become a popular product. So how to distinguish the quality of LED SMD lamp beads when purchasing?

The distinction of lamp bead bracket materials: At present, there are aluminum brackets, brass brackets, copper brackets, etc. on the market. Aluminum brackets are cheap, and copper brackets are expensive, and the prices are several times apart. Even if it is a copper bracket, the price of silver plating will vary. The market is usually called a good bracket, and most of them are made of silver-plated brass.

The distinction of welding wire data: The chip and the bracket are connected by gold wire welding process to complete the electrode connection. At present, there are two kinds of alloy wire and pure gold wire on the market, and pure gold wire is the best. Hongfucheng Optoelectronics uses pure gold wires to be divided into 0.7, 0.9, 1.0, 1.2, etc. according to the thickness.

Distinction of chip size: The reported chip size is usually in mil. If there is no high-magnification measuring microscope, it is usually impossible to distinguish. The larger the chip, the brighter. We can compare the chip size by calculating the chip area, such as 23X10, the area of the chip is 230 square mil, and it is a good way to distinguish the chip size by the chip area.

Model specifications of color separation, partial pressure and light separation: (1) Color separation: it is the color temperature classification, such as 3200K-3350K is the first file, the regular packaging factory will provide the color temperature BIN code, the smaller the color temperature classification, the better, the color temperature The bins are small, and the color uniformity of the light source light given is good. (2) Voltage division: It is the voltage binning of the chip, such as 3.0V-3.15V. For the light source is a hybrid interface, the voltage binning is controlled within 0.15V, so that the current distribution of the light source is uniform, which is beneficial to improve the light source. life. (3) Splitting: It is the brightness of the lamp beads, which is divided into lumens or light intensity. For the light source used for lighting, choose lumen. It is recommended to purchase LED SMD lamp beads, or based on light efficiency, products with high light efficiency will save energy and have a long life.
