Cob Led Heat Sink Calculator

Below are 2 illustrations of cob leds mounted to a heat sink with a layer of thermal interface material tim in between.

Cob led heat sink calculator.

Suitable candidates include the mechatronix lpf6050 zhc. This simple yet powerful calculator allows the rapid design and analysis of heat sinks by novices and experts in thermal analysis. Introducing the heatsinkcalculator an online calculator used to design analyze and optimize heat sinks in various flow conditions. The heat sink size calculator is based on a well established equation for estimating heat sink volume during the early stages of heat sink design.

For example let s say we are selecting a heat sink for an osram prevaled core z3 1100 led cob module which is 1100 lumens. The dissipated power pd pe x efficiency where the efficiency of the cob is around 32 or 17 75w x 0 68 12 07w. A led luminaire can be seen as an electrical scheme with the thermal resistances of the led internally the interface material and the led cooler is series. Calculate the required led heat sink the basics to do that is to understand the scheme at the right each part of the design adds up some heat due to individual thermal resistances of each material.

A reference link has been placed below the calculator for further reading. In our experience it generally estimates the overall heat sink volume within 15 of a final design. Some heat is also radiated to the ambient.
