Fabricant de luminaires led utilisant la téchnologie cob.

Garnatiled arose from the synergy of a french team settled in spain, a specialist of semi conductors with a research and development department settled in hong-kong and an assembly plant 80 kms away from hk allowing a coordination and an implementation of immediate process.
all our products are for the european ce standards.
garnatiled is working for you to get the last led technologies allowing you to obtain the equivalent of a classic bulb.

Garnatiled use cob technology:

With this technology, the led chips are in the form of a semiconductor chip, which is neither encased nor connected. the semiconductor chip is described as a "die". this led chip is processed by means of a special procedure which is called "die bonding". here the individual chips are placed on the pcb and using the wire bonding method, connected to the contact surface of the pcb, which are described as "pads". gold wires in the micrometer range are used for contacting. the cob technology allows for virtually limitless freedom of scope for the pcbs and thus serves as the basis for totally unique led solutions.

Reliability test

If requested, the resistance of the cob led modules against environmental influences at garnatiled can be verified in the form of various simulation tests such as a test with defined moisture (climatic exposure test cabinet test), temperature cycle test or the wet high temperature operating life test.

Photometry, radiometry and colorimetry

To ensure that our cob led modules are manufactured within the specified tolerances, photometric parameters such as luminous flux and colorimetric parameters such as the colour rendering index (cri) or the cie colour coordinates are measured and documented.
