Optical
Overview
The optical design of the High Power LED fixture drives other processes that will occur throughout the development process.
Selecting the right emitters and developing optics that maximize lumen output efficiency and consistency of light patterns will largely determine overall performance of your luminaire.
The process of defining the lighting needs and components to be utilized along with subsequent optical modeling and simulation is a fundamental piece of the overall project
Optical Process
Heatron provides services from beginning to end, through the entire development process, which saves you time and money.
- Pattern Definition

LED Emitter Selection
When working through the design process, Heatron’s design team selects or guides the customers’ emitter selection by first prioritizing the emitter performance characteristics
- Lumen Maintenance
- Reliability
- Efficiency
- Maximum life operating temperature
- Total Lumen output
- Beam pattern from LED
- Manufacturability

Light Pattern Definition
The development is started with a clear definition of the desired end result. The application determines the degree of freedom allowed in the pattern shape, intensity and light quality. 
- Transportation/Signaling/Automotive/Aviation – DOT, SAE and other regulatory agencies have well defined specifications controlling light output and pattern.
- Area/Street Lighting – The IES handbook defines various light patterns and requirements
- Architectural - IES provides definitions for various light patterns. There’s a high degree of freedom that is accepted and housing aesthetics often play an important part in tradeoff decisions. Light quality (CRI, CCT, Uniformity, Glare) are key factors.
- Medical/Industrial – The end customer controls pattern definition.
