LightFair, Fundamentals of Luminaire Design.
LightFair International (LFI) is the premier lighting exhibition in the US and it draws thousands each year. LFI is equal lighting education and product showcase with the first half of the conference filled with panel discussions, keynote events, and seminars with topics ranging from aesthetic lighting design to detailed lighting controls. As part of an […]
Bidirectional Scattering Distribution Function
Bidirectional Scattering plays a crucial role in evaluating the performance of optical systems and assessing the quality of optical components. As optical engineers, we are responsible for more than just the design and implementation of these systems for specific applications; we often rely on techniques ranging from simple interferometric setups to electron microscopes for surface […]
Expanding Zemax Capabilities with User Defined Objects
To assist with the computation of the paths of millions of light rays, optical engineers use specialized software to design and simulate optical systems. Zemax is the most popular optical design software and the one I prefer. It includes many built-in functions and objects but sometimes more specific objects are required. Zemax therefore allows user […]
Aviation Light Optic Design
Aviation Light is a critical component in ensuring the safety and efficiency of air travel. In the last month, I have had the need to travel several times by airplane. So, after several hours enjoying $15 sodas and $30 hamburgers at the airport gates, I started paying more attention to the different aviation light systems […]
Understanding STVZO Bike Light Pattern and Optical Design
STVZO (Straßenverkehrs-Zulassungs-Ordnung) is one of the most critical standards in the realm of bicycle lighting, ensuring compliance with legal requirements while enhancing the safety and convenience of cyclists. Adhering to these stringent standards is essential for providing effective illumination and meeting the necessary regulations for bike lights. Designing an STVZO-compliant light involves a deep understanding […]
How does a light pipe overmold work?
One common production method for light pipes is the overmold . This method uses an inexpensive light diffused plastic overmolded with a black case to generate a light-pipe. The “Win” keyboard key is one good example. “Win” key appearance to the observer. The black key body has a hole; during manufacturing, this hole is filled […]
