7) Straight plug is easy to install.

8) Dust-proof design, easy to keep the lighting surface clean.

Development concept:

Chip-on-board (COB) light sources have a small light-emitting surface (LES) and large luminous flux, so they are often used in directional lighting fixtures. However, keeping the COB small is extremely challenging because the compact arrangement accelerates heat buildup and impairs performance. Therefore, when designing COBs, improving luminous flux and reliability while controlling LES has always been the focus.

Based on this principle, GETIANLEDS high lumen density COB was developed.

GETIANLEDS flip chip COB package features:

1. Compared with standard front-mount LED packaging technology, GETIAN LEDS flip-chip packaging technology avoids wire bonding, so there is no risk of gold wire breakage.

2. Compared with standard flip-chip packaging technology, the eutectic bonding between LED chip and substrate in GETIANLEDS flip-chip packaging technology makes the whole device have excellent thermal conductivity.

3. For high-power COBs, the culprit of reliability degradation is heat:

The heat transfer efficiency of the AlN substrate of COB is as high as about 300W/(m•K), which is twice that of the Al substrate and six times that of the Al2O3 substrate.

Why is the Light Emitting Surface (LES) small?

1. Manufacturing cost:

Easier optical design: Smaller LES means easier secondary optical design, enabling more compact and portable luminaires.

2. Higher mobility:

Lower Manufacturing Costs: More compact luminaires should use less BOM and lower manufacturing costs.

Not only is it small, but it also achieves excellent performance

* High color rendering index

With reliable phosphor performance, proper mixing ratio and unique packaging process technology, the COB has a color rendering index (Ra) as high as 95 even at a CCT of 5600K.

* High reliability

The initial lumen flux maintenance rate of the high lumen density COB is greater than 98% after continuous lighting for 9000 hours at a driving current of 12 amps.

* Minimal color shift

The high lumen density COB shows a color temperature shift of less than +/-50K after 9000 hours and a chromaticity shift of less than +/-0.001 on the black body curve.
