Cob led heat sink calculator.

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. A reference link has been placed below the calculator for further reading. This simple yet powerful calculator allows the rapid design and analysis of heat sinks by novices and experts in thermal analysis. 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.

The dissipated power pd pe x efficiency where the efficiency of the cob is around 32 or 17 75w x 0 68 12 07w. In our experience it generally estimates the overall heat sink volume within 15 of a final design. This compact heat sink is 60mm in diameter and 50mm tall and it has a thermal resistance θs of 4 0 c w. 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.

Introducing the heatsinkcalculator an online calculator used to design analyze and optimize heat sinks in various flow conditions. 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. Suitable candidates include the mechatronix lpf6050 zhc.
