How to set the thermal resistance of COB?

Release date: 2017-11-15 Source: External station sharing:

When simulating a COB light source , its own thermal resistance is found in the specification, assuming 5 degrees per watt, when 14W is required  

1: How is the final thermal resistance calculated?
2: If the COB light source is ceramic, how much thermal conductivity should be set?
3: Area refers to the largest area of ​​the COB or the effective area of ​​the lamp bead.

For finite element analysis, you can try to use ansys to do it;

Actual measurement, environmental factors, test points, test errors, etc. have a greater impact on the final test results, and the final simulation results are difficult to explain what problems;

It is recommended to apply empirical values ​​or design in combination with ansys simulation, through physical evaluation;
