SMD LED, also known as SMD LED, is a simple lamp. Its light-emitting principle is to pass current through compound semiconductors. Through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of light emission.

Characteristics of SMD LEDs:

①The principle of luminescence is cold luminescence, not by heating or discharge, so the life of the component is about 50-100 times longer than that of a tungsten bulb, which is about 100,000 hours.

②No warm-up time is needed, and the lighting response speed is faster than ordinary lamps (about 3 ~ 400ns).

③ High electro-optical conversion efficiency, low power consumption, saving about 1/3 ~ 1/20 of energy consumption than light bulbs.

⑤ Good shock resistance, high reliability, and low system operating cost.

⑥Easy to be small, thin, lightweight, without shape restrictions, and easy to be made into various applications.

SMD LEDs are affixed to the surface of the circuit board, suitable for SMT processing, and can be reflowed. SMD LEDs solve the problems of brightness, viewing angle, flatness, reliability, and consistency. Compared with other packaged devices, it It has the advantages of strong anti-vibration ability, low solder joint defect rate, and good high-frequency characteristics. It encapsulates more LED chips in a smaller area, uses lighter PCB and reflective layer materials, and shows that the reflective layer needs to be filled. There is less epoxy resin. By removing the heavier carbon steel material pins and reducing the size, the weight of the product can be easily reduced by half. The volume and weight are only about 1/10 of the traditional plug-in components. After the use of SMD packaging, The volume of electronic products is reduced by 40% to 60%, and the weight is reduced by 60% to 80%, which ultimately makes the application more perfect.

The package of the in-line LED adopts the form of potting. The potting process is to first inject liquid epoxy resin into the LED molding cavity, then insert the pressure-welded LED bracket, put it in an oven to allow the epoxy resin to cure, and then separate the LED from the mold cavity and form it. Due to the relatively simple manufacturing process and low cost, it has a high market share.

Shenzhen Xiangguan Optoelectronics Co., Ltd. was founded in 2007. It is a national high-tech enterprise integrating R&D, production and sales.
