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/ 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/ 
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 / 
1.5mil COB / Purity 99.99%
High purity gold wire has better ductility. Resist high current shock.
Others/Poor Quality Products
1.0mil 1W/ 
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/  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 /
Notes
First one in China. (Especially for stage light, projector and track light)
