Thermal Shock Test Both of the PCB and dies substrate is ceramic, which similar in the thermal expansionCoefficient. No temperature shock will cause the dies failure and luminous decay and dead light Thermal expansionCoefficient of the Aluminum PCB is 4 times higher than the dies ceramic substrate; the temperature shock will cause the reliability problems Same as Aluminum PCB COB Light Engine
85℃ high temperature and 85% humidity Test Use of high quality packaging materials and result of high weatherability The market value of the light engine is lower than US$0.85/W might have a sever luminous decay in a short time The market value of the light engine is lower than US$0.60/W might have a sever luminous decay in a short time
Thermal Resistance Very low Low High
Thermalconductivity high thermal conductivity with large conductivity area for effective heat dissipation, ease of thermal management and low cost   Thermal conductivity is lower than the ceramic; large conductivity area for heat dissipation, ease of thermal cooling and low cost Thermal conductivity is low, thermal area is small and the heat is concentrated. More difficult thermal design, cooling costs are high
High voltage resistance >4000V <600V 6<00V
Finishedlampsproduct design with non-isolated power forUL / GScertification Qualify Difficult Difficult
Finishedlampsproduct design with isolated power forUL / GScertification Qualify Qualify, but Loss oflight efficiency Qualify, but Loss oflight efficiency
Power Matching Withhighvoltagesafety, any ceramicCOB5W and aboveare designed toVf> 24V,low currenthigh voltageto match thenon-isolated power supply to reducepowercosts, improvepower efficiency, enhance power supplyreliability In order to qualify the UL / GScertification, isolated power must be use; in result loss of power efficiencyand reliability.particularlyevident in highwattagefinished lampsproduct Same as Aluminum PCB COB Light Engine

Cooling cost Resistance is small, thermal path short with large thermal dissipation area; the cost of cooling can effectively reduce. Thermal path short with large thermal dissipation area, but resistance is larger than ceramic. Higher cooling cost than ceramic. Large thermal resistance and long thermal path, small thermal dissipation area, highcooling costs
Installintegration costs Directmountingon theheat sink and low cost. Directmountingon theheat sink and low cost. First solder on FR4 PCB or MCPCB and then fixed on the heat sink, the high cost is high
Cost of power supply matching ForUL / GScertification, non-isolated power supply can be used. Low cost. Non-isolated power supply must be used to qualify for the UL / GScertification. High cost. Non-isolated power supply must be used to qualify for the UL / GScertification. High cost.
