COB LEDs

In fact, COB stands for Chips on Board, a new technology of arranging LED chips on the screen or the board.

In this method, unlike SMD LEDs, the chip connections are sharply compressed and smaller, and light up evenly, like a one-piece LED panel.

In COB chips, the semiconductor chip is attached directly to the main board using a high-temperature thermal adhesive, and the connection to the PCB is made by wire. This wire is made of gold and is micrometer thick, which establishes electrical connection. Finally, all parts are covered with a layer to protect against damage and contamination. To create this layer, a method called so-called barrier and filling is used, by first drawing a barrier all over the parts, then covering the surface of the parts with a viscous material, and then filling the middle space with liquid. Which gradually hardens, filling.

COB lights can save up to 30% on operating costs. This savings occurs mainly in the cost of LED packaging and secondary lighting costs, which is an important issue for semiconductor applications and upgrades.

Basically, the purpose of producing COB lights is to have high-efficiency light sources, so that by reducing the current consumption and heat generated, the lighting produced by the new product is completely economical.

A COB light provides a better light source, resulting in more focused light, and the reflector can be controlled using a reflector.

Chrome reflectors around the diode can also be replaced and placed at different angles to make the light beam narrower or wider.

With bright lenses, more light can penetrate, which means they work better in rooms with high ceilings.

Among the products manufactured by Noorfan Company, various Street lights and Floodlights are produced using COB LEDs.
