i < mpn.length() && i < 4; i++) { if (Character.isLetterOrDigit(mpn.charAt(i))) { series.append(mpn.charAt(i)); } } ``` ### L1/L2-Prefix Series (Newer Products) For MPNs starting with `L1` or `L2`, extract the first 4 characters: ```java // L1T2-3070000000000 → L1T2 // L1M1-xxx → L1M1 // L1V0-xxx → L1V0 return mpn.substring(0, 4); ``` ### Numbered Series (Mid-Power) For MPNs starting with `L` followed by digits, extract until non-alphanumeric: ```java // L130-5780003000W21 → L130 // L135-xxx → L135 // L150-xxx → L150 for (char c : mpn.toCharArray()) { if (Character.isLetterOrDigit(c)) { series.append(c); } else { break; } } ``` --- ## Color Code Extraction Color codes are typically found after a dash in the MPN: ### For LUXEON Z and Rebel (LXZ1, LXML) Color code is the first character after the dash: ```java // LXZ1-PB01 → P (Power) or B (Blue) depending on interpretation // Extract position dash+1 int dashIndex = mpn.indexOf('-'); if (dashIndex > 0 && dashIndex + 2 <= mpn.length()) { return mpn.substring(dashIndex + 1, dashIndex + 2); } ``` ### For Mid-Power (L130, L135) Color code is positions 4-5 (after series prefix): ```java // L130-5780003000W21 → positions 4-5 after prefix if (mpn.length() >= 6) { return mpn.substring(4, 6); } ``` --- ## Compatible Series (Replacement Logic) The handler recognizes these cross-series compatibilities: | Series 1 | Series 2 | Compatibility Notes | |----------|----------|---------------------| | LXML (Rebel) | LXZ1 (Z) | Similar flux, different footprint | | L130 (3030) | L135 (3535) | Same technology, different size | **Note**: Cross-series compatibility indicates similar electrical characteristics but may require PCB redesign due to different footprints. --- ## Supported Component Types The handler supports these ComponentType values: | Type | Description | |------|-------------| | `LED` | Generic LED type | | `LED_HIGHPOWER_LUMILEDS` | Lumileds-specific high-power LED | --- ## Handler Implementation Notes ### Pattern Registration All patterns are registered for both `LED` (base type) and `LED_HIGHPOWER_LUMILEDS` (manufacturer-specific type): ```java // Each series is registered twice registry.addPattern(ComponentType.LED, "^L1T2.*"); registry.addPattern(ComponentType.LED_HIGHPOWER_LUMILEDS, "^L1T2.*"); ``` ### getSupportedTypes() Issue **Known Bug**: The handler uses `HashSet` instead of `Set.of()`: ```java // Current (mutable, non-deterministic order) Set<ComponentType> types = new HashSet<>(); types.add(ComponentType.LED); types.add(ComponentType.LED_HIGHPOWER_LUMILEDS); // Should be (immutable, deterministic) return Set.of(ComponentType.LED, ComponentType.LED_HIGHPOWER_LUMILEDS); ``` ### Package Code Extraction Notes 1. Series-based extraction takes precedence over suffix extraction 2. If no series match, suffix is extracted via regex `^[A-Z0-9]+` 3. Unknown suffixes are returned as-is (no default) --- ## Related Files - Handler: `manufacturers/LumiledsHandler.java` - Component types: `LED`, `LED_HIGHPOWER_LUMILEDS` - Similarity calculator: `LEDSimilarityCalculator.java` --- ## Learnings & Quirks ### MPN Format Variability - LUXEON MPNs have varying levels of detail after the dash - Some MPNs include flux bins, CCT values, and packaging codes - The same LED may have many MPN variants for different bins/CCT ### Low-Power Series Pattern The `LW Q18` pattern includes a space, which is unusual: ```java registry.addPattern(ComponentType.LED, "^LW Q18.*"); ``` This may cause issues with MPN normalization that removes spaces. ### Color Bin vs CCT - Color LEDs use color codes (R, G, B, A=Amber, PC=PhotonConversion) - White LEDs use CCT bins in the MPN (2700K, 4000K, 5000K, etc.) - The handler's `extractColorCode()` method handles both patterns ### Automotive Qualification - LXA2 and LXA3 series are AEC-Q102 qualified - Automotive MPNs may have additional suffixes for qualification level ### Handler Test Coverage As of January 2026, LumiledsHandler does not have dedicated tests. When adding tests: 1. Place tests in `handlers` package, NOT `manufacturers` package 2. Use `MPNUtils.getManufacturerHandler("LXML-PWC1")` for handler access 3. Test all series prefixes: L1T2, L1M1, L1V0, LXML, LXHL, LXZ1, LXCL, LXI8, LXA7, L130, L135, L150, LW Q18, LXA2, LXA3 ### Cross-Manufacturer Equivalents LUXEON LEDs compete with: - Cree XP-E, XP-G series - OSRAM OSLON series - Nichia 757 series - Samsung LM301 series These are NOT direct replacements due to different footprints and optical characteristics. <!-- Add new learnings above this line -->
