On Factors Influencing Thermal Resistance of LED Components

The thermal resistance of a material is its resistance against thermal conduction. The unit of thermal resistance is degree per watt, representing the temperature difference across a structure when a unit of heat energy flows through it in a unit time. After the LED is lighted and the thermal conduction stabled, as every watt of power on the chip surface being consumed, the temperature difference between the PN junction and the linking bracket or heating panel is the thermal resistance value of the LED.

LED Streetlights Cooling Design

When it comes to LED lights, many people focus on lumens and pay less attention to cooling.  In fact, LED lumens are increasing rapidly.  In 2006, lumens per watt in mass production reached 50 and it is still going up fast.  Heat transfer theory has matured, its channels are clear: conduction, convection, radiation and phase change (such as heat pipes).

Advantages and Weaknesses of LED Application

Unlike conventional incandescent lamps which need to convert the electricity into thermal energy first and then to light, LED illumination is achieved when a semiconductor crystal is activated so that it directly produces visible light in a desired wavelength range. With the continuous development of lighting technologies, more possible future applications of LEDs will be seen. Advantages and disadvantages of using LEDs are to be discussed as follows. Advantages of LEDs 1. Long Lifespan
