Introduction to Fill Lights

1. Fill lights are mainly divided into ring fill lights, flat panel fill lights, bar fill lights, etc. The ring fill light, due to its unique ring design, can create beautiful catchlights in the eyes of the subject, and is often used in scenarios such as live - streaming makeup and self - shooting. The flat panel fill light is thin, portable, and provides uniform light, making it suitable for indoor and outdoor shooting fill light. The bar fill light is small, flexible, and convenient for adding light in narrow spaces or at special angles.

2. In terms of application scenarios, fill lights are not only active in professional photography studios but also widely used in daily live - streaming and short - video shooting. Whether it is a beauty blogger showing off a delicate makeup look or a foodie shooting an attractive dish, the fill light can make the picture clearer, the colors more vivid, attract the attention of the audience, and improve the content quality.

Ultrasonic welding fill light

3. In the connection of the core components of the fill light - the LED lamp beads and the substrate, ultrasonic welding performs the best. It can accurately weld the LED lamp beads to the substrate, ensuring the reliability of the electrical connection, greatly reducing the contact resistance and thermal resistance. This means that the LED lamp beads can emit light more efficiently, and at the same time, the heat dissipation performance is significantly improved, effectively avoiding the light decay phenomenon caused by overheating, and enabling the fill light to always maintain a high - brightness and high - quality lighting effect.
