how to get paid with amazon pay: al203 alumina(thanks to this similar expansion-coefficient substrate which can avoid dead light ;darkness & have less light decreasing in case chips can be snapped of welded joint under the condition of temperature change , it can make the led chip have very good stability
ceramics cob optical light source has very super-high luminous efficiency:110lm/w because of the broad light source.
ceramics cob led plane light source belongs to integrated led light source module ,so the installation is very easy, it’s not necessary to consider the other things like technics design.
cob power led optical light source with ceramics base is very soft & uniform with very wide viewing angle.
2% light decreasing -10000 hours, 3 years warranty
emitting color :pure white and warm white
sensitive to esd
cob led with ceramics substrate is sintered at high temperature then covered silver heat can be dissipated very fast because chips get in touch with how to get paid with amazon pay straightly. when cob ceramic optical light source working, the nodal point between fluorescent powder & silica gel can be less than 120â°; led chips can be worked normally at about 80-90â°
cob flat surface light source can be broken down voltage at about above 4000v,
it has very high light conversion efficiency so that it can cut down the cost by matching no-isolated power supply with low current, high voltage
all products aging more than 8 hours before shipment to ensure reliable quality
providing technical support, such as choice of heat-sink, driver or lens
