Planning a Custom LED Lens? These 5 Factors Are Critical

Designing a custom LED lens isn’t just about choosing a beam angle — it’s a strategic process that requires careful planning. At Brightlx, we’ve helped clients around the world develop tailored lens solutions by starting with five core design inputs that make or break a project.

Whether you're building linear lights, floodlights, grow lights or more, here's what you need to consider:

1. LED Chip Type and Package

The shape and size of the LED (COB, SMD, CSP, etc.) affect how light is emitted and how it can be collected and redirected by the lens. We design the lens geometry to fit the specific LED footprint for optimal performance.

2. Target Beam Angle

Do you need a 10° spotlight or a 170° wide beam? Custom lenses allow you to achieve ultra-narrow, symmetric, asymmetric, or batwing distribution — all based on your application.

3. Mechanical Constraints

What is the maximum height, diameter, or mounting method? Do you need space for waterproof sealing or a specific holder structure? Mechanical integration is just as important as optical performance.

4. Application Environment

Is the fixture used outdoors? Will it be exposed to UV light, salt spray, or chemicals? We offer custom materials such as UV-resistant PMMA, PC, depending on durability needs.

5. Optical Requirements

How important is uniformity? Do you need to eliminate yellow rings, hot spots, or dual shadows? We can simulate and refine lens designs until your performance standards are met.

Final Thoughts

With proper design inputs, custom LED lenses can dramatically improve your product's visual and functional impact. Our team works closely with you from concept to production, making sure every detail is considered.
