Energy Advantage™

Our process of Heat Spreader™ material to dissipate heat from LEDs is unmatched by current technology available in the United States.

Junction temperature is the temperature at the point where an individual diode connects to its base. Maintaining a low junction temperature increases output and slows LED lumen depreciation. Junction temperature is a key metric for evaluating an LED product’s quality and longevity.

 

The three things affecting junction temperature are: drive current, thermal path, and ambient temperature. In general, the higher the drive current, the greater the heat generated at the diode. Heat must be moved away from the diode in order to maintain expected light output, life, and color.

 

The amount of heat that can be removed depends upon the ambient temperature and the design of the thermal path from the diode to the surroundings. (Source: DOE)

The Department of Energy advises: “Heat management and an awareness of the operating environment are critical considerations to the design and application of LED luminaries for general illumination. Successful products will use superior heat sink designs to dissipate heat and minimize junction temperature. Keeping the junction temperature as low as possible and within the manufacturer specifications is necessary in order to maximize the performance potential of LEDs.”

Benefits of Our Heat Spreader™ Technology

LED chips emit light after wired with power. About 75% of the electric power is turned into heat energy. In LED fixtures commonly used today, this heat energy is trapped in the fixture itself, limiting the LED’s performance and lifespan.

Our Heat Spreader™ technology moves the heat energy away from the LEDs, providing extended longevity and lumen output. The heat energy from the LED is transferred to the heat sink, instigating the Heat Spreader™ process." The temperature drop through this is about 1 degree C which is transferred through the back of the LED and solder of the heat sink.

Heat flow continues along the aluminum alloy heat sink, then transfers to the shell of the Heat Spreader™. The temperature drop through the shell is about 2 degrees C.

Heat flow enters the imbibition wick, which is made of a metal screen and adhered to the inner chamber of the Heat Spreader™. The heat flows to the work liquid inside the imbibition wick.

After the vapor has condensed back to liquid, the liquid naturally returns to the imbibition area to restart its process, absorbing heat and starting a new heat transfer cycle.

Our LED Lighting performs at one degree C above ambient temperature through the Heat Spreader™ technology .
