What are the advantages of COB surface light sources?

With the rapid development of science and technology, the energy problem in our country is also a huge problem that major enterprises need to face. Of course, SMD LEDs , plug-ins, SMDs, and high-power lamp bead products are also included, so in recent years, large or small enterprises are turning to energy-saving and low-consumption. In indoor and outdoor lighting fixtures, such as downlights, fluorescent tubes and street lamps, COB light sources have a wide range of applications. Compared with the traditional LED package, COB surface light source has gradually entered people's field of vision, so what advantages does it have compared with traditional LED devices? We together look.

First, the light quality of COB surface light source

Traditional LED lamp beads are used to mount multiple discrete devices on a PCB to form a light source component for LED applications. This can cause problems with spotlight, glare, and ghosting. The COB surface light source is an integrated package, and the surface light source has a large viewing angle and is easy to adjust, which reduces the loss of light refraction.

Second, the application cost of COB surface light source

Taking the needle lamp cob surface light in a haystack as an example, the process of patching and reflow soldering is omitted at the application end, thereby greatly reducing the production and manufacturing costs of the application end, which will facilitate the popularization of LED lighting as soon as possible. With the improvement of LED luminous efficiency, many new LED lighting fixtures have been developed, but the technical and cost barriers that hinder the promotion and application of LED lamps still need to be further overcome. The process using COB surface light source can reduce thermal resistance, improve light efficiency, prolong life and reduce application cost, greatly improve cost performance, and is beneficial to the popularization and application of LED lighting.

Third, the production efficiency of COB surface light source

The COB LED lamp bead is basically the same in production process as the traditional LED lamp bead. The efficiency of the COB LED lamp bead is basically the same in both the die bonding and wire bonding processes, but the efficiency of COB LED is much higher in dispensing, separating, splitting and packaging. The cost of labor and manufacturing of traditional LED lamp beads accounts for about 15% of the cost of materials, while the cost of COB surface light source is only about 10% of the cost of materials.

Fourth, the low thermal resistance of the COB surface light source

The thermal resistance of the traditional LED lamp bead system is: chip, solid crystal glue, solder joint, solder paste, copper foil, insulation layer and aluminum material, while the system thermal resistance of COB light source is: chip, solid crystal glue and aluminum material. It can be seen that the system thermal resistance of the COB light source is much lower than that of the conventional LED lamp bead, thus greatly improving the life of the LED.

We all know that high-power LED lamps have the disadvantage of glare, but our new light source solves this problem very well. At the same time, the problem at the cost is that it is also a product that is different from the previous LEDs in terms of volume and cost, and it can save cost and not to make some parts. Moreover, in the choice of materials, a new anti-aging material is used, which not only increases the service life of the product, but also has a great auxiliary effect on the diffusion of the light source.

Of course, in the production of the manufacturer, such products are integrated with each component, so those application manufacturers do not need to consider installation and other issues, which reduces the cost to a certain extent. Therefore, in terms of cost and application, COB is very likely to become the mainstream of the lighting market in the near future.
