Through hole LED, also known as through hole light emitting diode, is a widely used type of LED with a traditional through hole structure. It has been playing an important role in the lighting industry for many years. In this article, we will introduce the basic concept, application fields, and development trends of through hole LED, hoping to provide readers with a comprehensive understanding of this product.

Basic Concept of Through Hole LED

Through hole LED is a kind of LED with a traditional through hole structure. The LED chip is mounted on a lead frame with a lead wire, and then encapsulated with epoxy resin. This kind of LED has the advantages of high brightness, low cost, and easy assembly. It is suitable for various applications in the lighting industry. The main structure of through hole LED includes the following parts: 1. LED chip: The core part of the LED, which is responsible for emitting light. 2. Lead frame: A lead frame is used to hold the LED chip and lead wire. 3. Lead wire: The lead wire is used to connect the LED chip and the external circuit. 4. Encapsulation: The encapsulation is used to protect the LED chip and lead wire, and improve the heat dissipation performance.
