Introduction to Top-Emitting Chip SMD LED

Top-Emitting Chip SMD LED is a type of LED that emits light from the top surface of the chip, as opposed to the traditional side-emitting or bottom-emitting LEDs. This design allows for better light extraction and higher efficiency, making it ideal for applications where a wide viewing angle and high brightness are required.

Working Principle of Top-Emitting Chip SMD LED

The working principle of Top-Emitting Chip SMD LED is based on the semiconductor properties of the material used, typically gallium nitride (GaN). When an electric current is applied to the LED, electrons and holes recombine at the junction, releasing energy in the form of light. In a top-emitting chip design, the light is directed towards the top surface, allowing for better light extraction and higher efficiency. The top-emitting structure typically involves a transparent conductive layer, a semiconductor layer, and a reflective layer. The transparent conductive layer allows for the passage of electricity, the semiconductor layer emits light, and the reflective layer helps to direct the light upwards.
