Light pipes provide efficient light transport for applications such as machine vision, lighting, and medical imaging. A light pipe can be thought of as a light conduit, where light entering one end is transmitted between two points without significant absorption or scattering. The PLPC2-7MM is a light pipe designed to transmit data in the visible light spectrum.

The PLPC2-7MM is a plastic light guide, offering a mounting size of 19.2mm x 7.5mm. The light pipe fits a standard medium-base socket and has a maximum output of 3.25 lumens. It can be tweaked for higher power applications with the addition of a PLPC amplifier. The product is used in numerous industries such as medical, automotive, CCTV, and IoT applications.

The product features an internal reflecting surface which reduces the total optical losses compared to other light guides. The light pipe features a 25° viewing angle and 35° total beam angle giving it impressive lighting and light transmission performance. This makes the product suited for applications such as replacing medical lighting, backlighting displays, automotive interior lighting, or general lighting automation.

The PLPC2-7MM light pipe uses a combination of total internal reflection (TIR) and transmittance in order to efficiently transmit the light from the source to the target. Total Internal Reflection occurs when light is incident on a medium boundary that has a higher refractive index than the incident medium. When the light strikes the surface, part of it is reflected while part of it is pushed to the boundary. The light is then reflected internally and sent towards the output of the light pipe. The transmission and reflection of the light through the light guide then determines the location of the output.

The light pipe is also designed to minimize the amount of light loss that can occur. This is achieved by using reflective materials on the inside of the light guide, such as aluminum and other reflective coatings, to direct the light within the light pipe to the output. This process helps to keep the light in the optical path, preventing it from spilling out and therefore, decreasing the amount of light losses.

In addition, an additional layer of plastic is added on top of the reflective layer to increase the lifespan of the light guide and make sure that a consistent light output is achieved. This is done by minimizing the scattering process of the light within the guide and consequently preventing significant heat build up and light loss that can occur with other light guides.

The PLPC2-7MM is the perfect light pipe for applications requiring a reliable light transmission over a distance of up to 2 metres. Its efficient light transmission ensures that the light is delivered accurately to the target and ensures a bright and consistent output. It can be used in multiple applications such as medical lighting, automotive interior lighting, backlighting displays, and other similar lighting applications requiring efficient light delivery.
