GETIAN High Power LED Material Introduction & Comparison
|
Chip |
Getian/ Reliable Products | Bridgelux /Epistar |
Getian has got certificate of Authorization from Bridgelux and Epistar. Build strategic partnership with Bridgelux. High reliability. |
|
Others/Poor Quality Products |
Other brand/Â fake Bridgelux & Epistar |
Fake chips cost much less. A huge price gap.The actual power is much lower than claimed.(eg:100w usually 70w actual.)Shorter life span with great light decay. |
|
| Notes | Fake chips lack reliability. Be cautious especially when using outdoor. Hard and costly to maintain. | ||
|
Phosphor/Â Silica gel |
Getian/ Reliable Products |
Intermatix/ patented recipe and improved technique. Find a best combination of the ratio between phosphor and silica gel. | When temperature goes high, phosphor can resist it and keep the CCT value stable and even from different angle. |
| Others/Poor Quality Products | Intermatix/ others (recipe unknown) | Color temperature will drift when temp. goes high. CCT not even distributed from every angle. | |
| Notes | Our phosphor recipe has been successfully applied for 10 years. | ||
| Gold Wire | Getian/ Reliable Products |
1.2mil 1W /Â 1.5mil COB / Purity 99.99% |
High purity gold wire has better ductility. Resist high current shock. |
| Others/Poor Quality Products |
1.0mil 1W/Â 1.2mil COB / Al alloy |
Easy to break, more likely lead to led failure. |
|
| Notes | About 80% led failure comes from the break of the gold wire. | ||
| BBOS Technique | Getian/ Reliable Products | Gold wire double attach method and small arc, soldering ball | BBOS technique increases reliablity and decreases the risk of the break of gold wire. |
| Others/Poor Quality Products | One time soldering | Higher risk of the break of gold wire. | |
| Notes | No extra soldering ball or small arc added will cause potential risk of wire soldering point falling off. | ||
| Copper Base/ Soldering Pins | Getian/ Reliable Products | Red Copper/ Copper covered with silver/ PPA (white part) | High heat conductivty. Red Copper: 400W/mK |
| Others/Poor Quality Products | Yellow Copper (brass) / Aluminum, Steel | Low heat conductivity. Yellow Copper: 100W/mK. Aluminum: 205W/mK. Steel is easy to corrode. | |
| Notes | The heat conductivity of red copper is nearly 4 times higher than brass. PPA material has good high temperature resistance | ||
| Color Separation | Getian/ Reliable Products | 2 times | Guarantee good color unity. Normal range within + -250K |
| Others/Poor Quality Products | mostly 1 time | Wider range or not so consistent. | |
| Notes | Phosphor Spraying (first time check); Binning (Second time check.) | ||
| Reliability/ Â Warranty | Getian/ Reliable Products | 4 years warranty | Real Life test report, RoHS, SGS,LM-80 Certification |
| Others/Poor Quality Products | Unknown | / | |
| Developing Ability | Getian | Brand-New flip chip led released. Max power up to 300W. Lighting area 1.4mm². High luminous intensity: 50LM/mm² | Strong developing team. Improve current production line. And release new and high-end products regularly. |
| Others Company | Unknown | / | |
