LED (or light-emitting diode) is the most commonly used indicator in electronic products. However, LEDs themselves are rarely used in camera signal jammer devices. They are usually used in combination with LED light pipes: the unique structure increases visual feedback on the user interface. In this article, we define light pipes as a tool and discuss its applications and benefits to engineers.
What is an LED light pipe? LED light pipes (also known as light guides) are transparent coverings or structures with excellent light transmittance, which can be used to transmit light from surface-mounted monitoring shield systems or through-hole LEDs to the user interface (eg "ON/OFF" Indicator light) LED light pipe is a cost-effective, efficient and flexible solution that can be used for visual indications in a variety of electronic devices and equipment. There are two main types of LED tubes: rigid and flexible. The rigid light pipe is made of glass or polycarbonate and is directly mounted on the camera. Due to the rigid design of the former, they have a vertical or right-angle direction, so they are not suitable for transmitting light in sharp bends. On the other hand, flexible light pipes are made of optical grade fibers. They are connected to the LED adapter mounted on the PCB and can transmit light between sharp bends and steep angles. Factors to consider when choosing LED light pipes Electrical engineers should consider the following factors to help them choose the best camera shield light pipe for their design.
Placement is one of the most important considerations when choosing a light pipe is knowing how to place it. In addition, the supervisory shield design engineer should know the maximum distance between the light pipe and the LED. Rigid-that is, a vertical or 90-degree light pipe is suitable for LEDs mounted directly on the PCB behind the panel. In addition, flexible light pipes are ideal for LEDs mounted at a wide angle from the front of the panel (or relatively far away). Luminous rate: Another factor to pay attention to is the amount of light emitted by the light pipe. The luminosity depends on the material type of the light pipe and the shape of its lens (the front part of the light pipe). The light pipe should at least capture the light emitted by the light source.
