**Improved Thai translation:**
โปรไฟล์วงรี LED สีเต็ม
**Explanation:**
- Removed "รูป" (unnecessary classifier before วงรี; ellipsoidal is already a shape descriptor)
- Kept the concise nominal form appropriate for product naming
- "LED สีเต็ม" (full-color LED) maintains proper Thai word order for technical specifications
- The improved version is more natural in Thai technical terminology while preserving all technical accuracy
