Introduction to Top-Emitting PLCC SMD LED

Top-Emitting PLCC SMD LED is a type of surface mount LED with a unique design that allows for light emission from the top surface. Unlike traditional LEDs that emit light from the side or bottom, top-emitting PLCC SMD LEDs provide a more uniform and efficient light distribution. This is achieved by using a reflective lens or a reflective pad on the top surface of the LED package.

The PLCC (Plastic Leadless Chip Carrier) package is a popular choice for SMD LEDs due to its compact size, ease of assembly, and cost-effectiveness. The top-emitting design of PLCC SMD LEDs further enhances their performance and versatility in various applications.
