Heatron|Optical Lighting Capabilities from Heatron

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. 

This process of defining the lighting needs, components to be utilized and subsequent 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
• Emitter Selection
• Modeling & Simulation
• Photo-Realistic Rendering
• Standard vs. Custom

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.

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

Standard vs. Custom

Standard Lens Designs are available from many sources

Criteria for choosing between off-shelf optics and custom:

• Need to offer a light pattern specific solution
• Light output can differentiate end product in the market
• More robust product design with integration of custom optical solution
• Efficiency - Limit coupling losses often experienced with OTS optics
• Control over efficiency influences generating a higher overall efficacy
• Anticipated production quantities
• Development Time Schedule
