Application engineering

Bridgelux specification services, expressed as testable inputs

Project support is organized around photometric targets, electrical interfaces, thermal constraints and validation evidence. Each stage produces information that a lighting designer, luminaire engineer or controls specialist can review.

A four-gate validation method

  1. 01

    Define the operating point

    Record drive current, expected case temperature and required lumen package. Nominal source output without these conditions is not a sufficient design input.

  2. 02

    Model the distribution

    Use the applicable photometric file in the project model, then check task illuminance, uniformity, UGR and spill-light constraints.

  3. 03

    Build and measure

    Prototype the intended optic, thermal path and driver. Measure electrical power, output and color after thermal stabilization under documented ambient conditions.

  4. 04

    Freeze the specification

    Capture approved operating limits, component references and verification criteria for procurement and production control.

Scope boundary: Simulation files predict performance from measured source or luminaire data; they do not replace complete luminaire testing. Final results depend on optics, thermal design, driver tolerances and installation conditions.

A source-level LM-80 record and a TM-21 projection describe lumen-maintenance behavior under defined case temperatures. They cannot establish L70 lifetime for a finished product without the luminaire thermal path, drive profile and duty cycle. Likewise, a nominal 150 lm/W source point is not a system efficacy claim after optical, driver and thermal losses.

Sample validation should state stabilized ambient, measurement instrument, drive current and warm-up time. The project owner then determines whether an LM-79 report, safety evaluation or controls commissioning test is required.

Prepare a reviewable LED source brief

Include flux, CCT, CRI, drive current, dimming method and thermal envelope so the first review can focus on measurable fit.
