Led heat sink design guide

The LUXEON Custom Design Guide provides important details about operating temperatures for each LED emitter package. Once you determine your target temperature, a thermal model will allow you to consider the impact of factors such as size, type of heat sink , and airflow requirements. For subsequent discussion and simulation in this document, we assume the PCB is mounted to an infinite heat sink that maintains the back side of the board at . However, it may not be optimized in performance, size or shape for the target application.

LED heat sink for your new LED lighting design.

A custom solution provides the .

Now, we will discuss them one by one.

Define your expected Temperature: First of all, define your ambient temperature . Keep in mind that an enclosure around the LED cooler, tilting and other . Introducing the HeatSinkCalculator, an online calculator used to design , analyze and optimize heat sinks in various flow conditions. This simple yet powerful calculator allows the rapid design and analysis of heat sinks by novices and experts in thermal analysis. If you are unfamiliar with cooling electronic components such as high power LEDs, then before reading any further, we highly recommend that you watch this excellent video tutorial about Thermal Heatsink Design featuring Dave . This article, written by ATS CEO, Dr.

When designing heat sinks for Big Chip LEDs, the primary objective is to determine the junction temperature of the LED at operating conditions. The most simple method to determine the temperature is to use thermal resistances. The following discussion explains the fundamental principles of thermal . SynJet PARLED Cooler with Heat Sink Design Guide.

The thermal, mechanical, and electrical aspects of the luminaire are key design challenges. The LED drive circuit, the SynJet drive circuit, . Most of the electricity in an LED becomes heat rather than light ( about heat and light). If this heat is not remove the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Both natural convection and forced convection may be used to effectively convect heat away from the LED Array.

Heat Sink Selection Guide thermal solutions including natural and forced convection, high power, fan, liquid cooling, heat pipe tech. To summarize, LED design engineers are facing more demanding thermal management requirements as power levels increase and package sizes decrease. Solutions using conventional metal extrusion heat sinks are becoming thermally ineffective and too large and bulky for emerging products.
